141 : User Wants to set the starting day in Calendar as “Monday” instead of “Sunday”. How to get it done?
Ans : Change the user locale to “English ( United Kingdom ) ” in Personal information or User record.

142 : Why CSS is not working in PDF created by Visualforce ?
Ans : In Many cases, i have observed problems faced by my colleagues and complaining that CSS is not working when they try to render any Visualforce page as “PDF”. Same Question is asked many times in Interviews also. Basically there are two ways:

1. Use “apex:stylesheet” tag to import external CSS file
2. Wrap “Style” tag inside “Head” tag in Visualforce

143 : How to get Ip Address of User in Apex?
Ans :

String ipAddress = ApexPages.currentPage().getHeaders().get('X-Salesforce-SIP');

True-Client-IP has the value when the request is coming via the caching integration.
X-Salesforce-SIP has the value if there is no caching integration (sandbox, developer edition orgs) or via the secure url.
Thanks to TechNrd for this tips.

144 : How to get total number of Child records in Lookup relationship?
Ans: As Rollup Summary field is only supported in Master detail, we cannot use it for Lookup. There are following two ways (If anyone has any other idea please comment).

1. Inline Visualforce page
2. Trigger on Child Object, which will update field in Parent record if child record is inserted, deleted or undeleted.

145 : System admin has created a Visualforce for Account. In future he created few more new Fields. How could System admin can code Visualforce so that in future if any new field is added or existing field deleted. It should reflect in Visualforce without changing anycode?
Ans : It can be done with help of Field Sets. Please read this article.

146 : Once you convert lead, Few fields on lead should be reset so that sensitive information should not be queried using SOQL. How to get this done?
Ans : Once lead is converted, its READ ONLY. we cannot update it using Apex or Trigger. However we can use “Before Update” trigger on lead and check for fiels “IsConverted“. If its true means lead is going to be converted so reset all fields in that case.

147 : How to convert carriage returns in Textarea to Line Breaks in Visualforce?
Ans : We can use “<apex:outputField>” instead of “<apex:outputText>”. It will maintain formatting automatically.

148 : How to handle comma within field while uploading using DataLoader ?
Ans : Data Loader cannot handle this implicitly because there is no logical path to follow. In case your Data Loader CSV file for import will contain commas for any of the field content, you will have to enclose the contents within double quotation marks ” “. Data Loader will be able to handle this.

For example :

Column_1__c,Column_2__c,Column_3__c
Shiva,"Jitendra, Minal",Soft

If you are creating the import CSV in Excel, the quotation marks will be inserted automatically by Excel whenever a comma is detected in any cell – Saving the CSV in Excel and opening the same in Notepad reveals the enclosing quotation marks for cells containing commas.

149 : In Master Detail Relationship :
OWD for Parent is public Read Only.
If User has – Create, Edit Permission on Master as well as Detail Object.

While creating record for detail object he selects parent record which is not created by him. What will happen in this case ?

Ans : He will get an error, because in order to add child record user must have edit permission in parent master record.

150 : Difference in “Export” and “Export All” in Data Loader in Salesforce?
Ans :
Export : It is used to export the Salesforce Data(excluding recycle bin’s data) into your local system.

Export All :  It is used to export the Salesforce Data(including recycle bin’s data) into your local system.

Many time, we need something like get all cases related to Parent Account of Opportunity. We can simply create a report for Case and add Condition for Account Name. Using Some Custom Link, we can always Change Account Name and same report can be used many times.

While navigating to community i found very interesting and useful information regarding dynamic Filter in Reports.I thought that Dynamic Filters inside Salesforce is not possible but It is Possible.

Salesforce does not have any official documentation on this, but here how it works.

Lets have look in below image:

Dynamic Filter in Reporting

Above report have three Filters. First Filter will be considered as “pv0″, second filter will be considered as “pv1″ and so on.

In URL, we can provide parameter for Pv0, Pv1 like in above image.

Now, we can create a formula field to create a dynamic link which will open report. Something like

https://ap1.salesforce.com/{!ReportId}?pv0={!MergeField0}&pv1={!MergeField1}

In this example, we will create a simple List View button and add on “Search Layout” of that object.

Salesforce Mass Delete Button – List View

So, create a new Custom Button with following property:

1. Display Type :  List Button
2. Behavior : Execute JavaScript
3. Content Source :  OnClick JavaScript

and use below Source code:

{!REQUIRESCRIPT("/soap/ajax/21.0/connection.js")}

//Below ObjectType can be replaced by anyObject. I have used "Test Name"
var records = {!GETRECORDIDS($ObjectType.Test_Name__c)};

if (records[0] == null) {
    alert("Please select at least one record.")
} else {

    var opt = confirm("Are you sure you want to delete selected records ?");
    if (opt == true) {
        var errors = [];
        var result = sforce.connection.deleteIds(records);
        if (result && result.length) {
            var numFailed = 0;
            var numSucceeded = 0;
            for (var i = 0; i < result.length; i++) {                 var res = result[i];                 if (res && res.success == 'true') {                     numSucceeded++;                 } else {                     var es = res.getArray("errors");                     if (es.length > 0) {
                        errors.push(es[0].message);
                    }
                    numFailed++;
                }
            }
            if (numFailed > 0) {
                alert("Failed: " + numFailed + "\nSucceeded: " + numSucceeded + " \n Due to: " + errors.join("\n"));
            } else {
                alert("Number of records deleted: " + numSucceeded);
            }
        }
        window.location.reload();
    }
}

In above code, we only need to change line number 4 for Object Type.
Once you are done with above button, add button in Search Layout’s List View as shown in below Image.

Code taken from Salesforce Cookbook

Before going ahead let’s see the drawbacks of “Standard Mail Merge”:

1. It runs on Client side and needs ActiveX Control
2. It needs Internet Explorer
3. It does not work with Office 2010, it works only for Office 2003 and 2007
4. Windows 7 is not supported and causes unexpected error many times. It supports Windows XP and Windows Vista only

The solutions to all above problem is “Extended Mail Merge (XMM)” template which is free and native Salesforce solution.

Following are the advantages of “Extended Mail Merge (XMM)”:

1. It runs on server side and does not require installation of any ActiveX Control
2. It runs on almost al major browsers including firefox, Chrome
3. It supportes Office 2007 as well as Office 2010 (document must be saved in a 97-2003 DOC format)
4. We can save output into “Document” tab
5. XMM can send final word document in email itself

NOTE: Mail Merge & Extended Mail Merge uses same templates: “Setup | Communications Templates | Mail Merge Templates”

There are few limitations in XMM also like:

1. At a time, it can merge only 1000 records.
2. Template size cannot exceed 1MB of size.
3. It will access only those fields for which current user have access, it respects Field level security (FLS)

How to enable “Extended Mail Merge (XMM)” ?
We have to contact Salesforce to enable this feature in our Salesforce Organization.

How to activate “Extended Mail Merge (XMM)” , once it is enabled by Salesforce?
Navigate to “Setup | Customize | User Interface” and select checkbox “Activate Extended Mail Merge”. We can also select to save XMM result in Document tab as shown in below snap.

Insert Field in Extended Mail Merge Salesforce

Activate Extended Mail Merge – User Interface – Salesforce

Before using XMM , we have to create template in Microsoft Word. So, lets see how to create template.

For this article, let’s say our template is going to be used by “Contact” object and content should be as simple as :

Hello «Contact_FirstName»,
Phone Number - «Contact_Phone»
Regards
Shivasoft

In above paragraph, “CONTACT_Name” needs to be replaced by actual contact name. For this, we need API name of that field from Salesforce which is “Name”. Now create above template in Microsoft word and place the cursor where we want value to be appeared and navigate to “Insert | Quick Parts | Fields”.

Insert Field in Extended Mail Merge Salesforce

New window will appear, select MergeField and enter API Name as shown in below image.

Note : While entering API name of any field, It should be prefixed by Object name and Underscore  . For Example, API Name in Contact Should be referred as Contact_Name. (Object_FieldAPIName) .

Insert Field in Template – Salesforce

Now, go to Salesforce and navigate to “Set up | Communication Templates | Mail Merge Templates” and Upload recently created template.

Now to check that whether template is working or not. Navigate to Contact Tab and select “Mass Mail Merge” link present at bottom.

Step 1:
Select List of Contacts for which you want to run “Mail Merge” template.

Step 2:
Select Document Types to Generate. The Supported document types are documents, envelopes and labels. You can also select if you want to Log an activity that mail merge documents were generated for those records.

Step 3:
Select Document templates to be used by “Mass Mail Merge” which we have created in this article. In this step we can select that all documents to be generated in single word document or we have to create separate word files.
Once we click on finish button, we will get messag that email will be sent to email id once document is generated.

Extended Mail Merge – XMM Confirmation Window

Point to Remember:

• Prefix the field label with the type of record. For example, “Account_MarketCap” for an account field named MarketCap.
• Convert all spaces to underscores. For example, a custom opportunity field named “Product ID” becomes “Opportunity_Product_ID”.

However, Thanks to Salesforce that we have “Field Set”.

With the Help of “Dynamic Visualforce Binding” and “Field Set” we can create effective Visualforce pages with ability to change Fields and its Sequence any time without modifying any code.

Let’s start with using Field set in Salesforce.

Step 1: Creating Field Set

First we need to create a field set. For this article, I am using custom object named “Question__c”.

We have to navigate to setting page of that object and then “Field Sets”. Create a new Field Set and add required field in Sequence as displayed in below image.

Create Field Set in Salesforce

Assume that field set name is “Add_Question”.

Step 2: Use Field Set inside Visualforce using Dynamic Binding

Now, we are ready to use Field Set inside our Visualforce code. Following is code snippet of one of my Visual force page :

<apex:repeat value="{!$ObjectType.Question__c.FieldSets.Add_Question}"  var="f">
			<span  class="label" style="align:right"> {!f.label}  </span>
			<apex:inputField value="{!que[f.fieldPath]}" required="{!OR(f.required, f.dbrequired)}"/>
</apex:repeat>

As you can see in above code snippet, Field set can be accessed inside Visualforce like “{!$ObjectType.Question__c.FieldSets.Add_Question}”.

To get label of field, simply we can use “{!f.label}”.

To check, if field is required we can use “required” or “dbrequired” property.

We are getting fields dynamically by notation “{!que[f.fieldPath]}”. Where “que” is object defined inside Apex class.

Step 3 : Using Dynamic SOQL to get value – Optional

This step is Optional. If your VF page is working in “New or Insert” mode then there is no need to populate values inside variable “que”. However what if VF page works in Edit mode? How do we know, which fields are accessed? In this case we have to use Dynamic SOQL.

First we will get list of all fields used inside Field set using below method:

/**
*
* Get Fields from Field Set. It is not used on VF, It used to create Dynamic SOQL for Edit mode.
*/
public List getFields() {
	return SObjectType.Question__c.FieldSets.Add_Question.getFields();
}

Now, we will try to create Dynamic SOQL which will get record on basis of Id and will be assigned to object “que”.

/**
* On basis of field set, Create Dynamic SOQL
*/
private Question__c getQuestion_DynamiCSOQL(String quesId) {
	try
	{
		String query = 'SELECT ';
		for(Schema.FieldSetMember f : this.getFields()) {
			query += f.getFieldPath() + ', ';
		}
		query += 'Id, Name FROM Question__c WHERE Id = \''+quesId+'\'';
		return Database.query(query);
	}
	catch(Exception e)
	{
		Utility.addError('There is error while Fetching existing Question using Dynamic SOQL in Field Set. Error Detail - '+e.getMessage()); //This is Utility Method to display error message on VF Page
	}
	return null;
}

I hope, this article will help you. However, there are cases when you need to access Field Set even though Object name and Field Set name will be supplied dynamically.

Get Fieldset Fields in Apex dynamically when Object Name and FieldSet name is supplied at runtime

public static List readFieldSet(String fieldSetName, String ObjectName)
{
    Map<String, Schema.SObjectType> GlobalDescribeMap = Schema.getGlobalDescribe();
    Schema.SObjectType SObjectTypeObj = GlobalDescribeMap.get(ObjectName);
    Schema.DescribeSObjectResult DescribeSObjectResultObj = SObjectTypeObj.getDescribe();

    Schema.FieldSet fieldSetObj = DescribeSObjectResultObj.FieldSets.getMap().get(fieldSetName);
    return fieldSetObj.getFields();
}

We can test above code in Developer Console as below:

 List fieldSetMemberList =  Util.readFieldSet('Account_FieldSet','Account');
for(Schema.FieldSetMember fieldSetMemberObj : fieldSetMemberList)
{
    system.debug('API Name ====>' + fieldSetMemberObj.getFieldPath()); //api name
    system.debug('Label ====>' + fieldSetMemberObj.getLabel());
    system.debug('Required ====>' + fieldSetMemberObj.getRequired());
    system.debug('DbRequired ====>' + fieldSetMemberObj.getDbRequired());
    system.debug('Type ====>' + fieldSetMemberObj.getType());
}

You can read Apex Documentation regarding FieldSet here

Prerequisites:

• Heroku Account, you can sign up here – https://api.heroku.com/signup/devcenter
• Eclipse 3.7 or Higher
• E-Git Plugin , more information on set up of E-Git – http://shivasoft.in/blog/salesforce/salesforce-git-eclipse-egit-better-and-distributed-source-control/

Installation and Set up:
First we will need to Install Heroku Plugin in Eclipse. To install it, Navigate to “Help | Install New Software” and click on “Add” button.

Give any name in website like “Heroku Plugin” and enter this URL in Location https://eclipse-plugin.herokuapp.com/install and click on “Ok” and Finish Installation. It will install the Heroku Plugin required to start your first Plugin.

Next step is setting up your Credentials for Heroku :

Navigate to “Window | Preferences | Heroku”, Here either enter your UserName and Password of Heroku Account and click on “Login” or enter you API key, which you can find by logging into your Heroku Account.

Setting up Credentials for Heroku in Eclipse

Creating SSH Key :

Heroku uses Git to push and pull code from Heroku. For this you can use E-Git plugin of Eclipse. You can also visit this article for complete tutorial. So, for communication between Heroku and Git we need SSH. Navigate to “Windows | Preferences |General | Network Connections | SSH2 ”. Navigate to “Key Management” tab and click on “Generate RSA Key”. After Generation of key click on “Save Private Key”.

Generate SSH Key in Eclipse for Heroku

Now, after generation of RSA key Navigate to “Heroku” and click on “Load SSH Key” and select file which you have saved recently.

Load SSH Key in Heroku using Eclipse

Now, till this we have done all the configurations. Start with creating our first “Hello World” program from Template using Jetty.
Navigate to “New | Project | Heroku | Create Heroku App from Template” and click on Next.

Select Application template from new Heroku Project

On Next screen select “Embedded Jetty-Servlet application” and click on Finish. After creation of sample project, open “Main.java” file and run it.

Now open browser with URL http://localhost:8080/ and you should able to see Jetty Page. If you are able to see the Jetty Startup page, means everything is good. Now navigate to http://localhost:8080/hello , you will see text “Hello Heroku” just like below screen.

Getting Started with Embedded Jetty in Heroku

You can make modifications in “HelloServlet.java” by replacing below line with some other Text.

<br />out.write("Hello Heroku".getBytes());<br />

Deploying Modifications to Heroku from Local System:

Now, as we are done with making modifications in local code, commit the changes in Git by “Right Click on Project | Team | Commit”. You need to Enter Commit Message like this:

Commit Changes to Git – Heroku

After Committing the Changes, Navigate to “Right Click on Project | Team | Push to Upstream”.

Push to UpStream in Git for Heroku

Now, if everything is good, Heroku will receive all you local Changes and build application again on its server.

Heroku Build Succeed

Now you can run this application by logging into Heroku and make modifications that’s suits you like Salesforce Integration or any other.

You can also visit this official Heroku tutorial, which explains in very detail about Heroku Deployment using Eclipse and other important Configurations.

131. What will happen if you try to update record in After Trigger Context?
Ans : You will get an error saying “record is Read only”.

132. Let’s say we have to update the same record in After Trigger context. Is there any way or workaround?
Ans : If we create a new instance of an SObject in the Apex Trigger in memory using the Id of the newly created record as provided in the After Trigger context, we can perform an Update DML statement and not get a read only error. This is because in Apex, the SObject is seen as a new reference (even though the records have the same SFDC ID) and therefore is eligible for DML operations. The below snippet of code illustrated this working and not working.

List<Contact> originals = new List<Contact>();
if(mirrorResultMap.values().size() > 0)
{
	for(Contact origContact : contactRecs.values())
	{
		Contact mirrorContact = mirrorResultMap.get(origContact.Id);
		//origContact.Linked_Contact__c = mirrorContact.Id; //Link the Original Record tot he Mirror Record WILL FAIL
		Contact origContactUpdate = new Contact(Id=origContact.Id, Linked_Contact__c = mirrorContact.Id); //This will WORK
		originals.add(origContactUpdate);
	}
	//update contactRecs.values(); //Update the Records -> THIS WILL FAIL AS ITS ORIGINAL RECORDS IN MEMORY
	update originals;
}

133 . When loading data into date fields such as Opportunity Close Date using the Data Loader, the date displayed in the application is sometimes one day earlier than the date in the file. What may be the reason and solution ?
Ans :
The reason for this is that fields such as Close Date are actually date/time fields. When a date is loaded without specifying the time, the time is defaulted to 00:00 – midnight. When another user is in a time zone which is behind the current user’s time zone, the date will show on the previous day. For example:

20 August 2008 00:00 in Paris is 19 August 2008 23:00 in London

Similar issues can arise when daylight savings time begins or ends.

Two simple solutions to this are:
1) Specify a time as well as a date when loading dates using the Data Loader.
or
2) Switch your PC’s time zone to Hawaiian time before starting up the Data Loader.

134 : System.debug() statements are included against script count?
Ans : Any statement ending with semi-colon will be included against script count. There is very good article by Abhinav explaining this here.

135 : While trying to access javascript code from some CDN like Google, we get error something like “attempt to run uG request”. How to resolve it ?
Ans : While providing URL, do not specify the protocol. Use like this:

<script type='text/javascript' src= '//ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js'></script>

136 : Explain ActionFunction, ActionSupport and ActionPoller in Visualforce.
Ans:

apex:ActionFunction : This component helps to envoke AJAX request (Call Controllers method) directly from Javascript method. It must be child of apex:form. Read here – www.salesforce.com/us/developer/docs/pages/Content/pages_compref_actionFunction.htm

apex:ActionSupport : This component adds Ajax request to any other Visualforce component. Example : Commandlink button has inbuilt AJAX functionality however few components like OutputPanel does not have inbuilt AJAX capabilities. So with the help of this component, we can enable AJAX. Read more here.

apex:ActionPoller : This is timer component which can send AJAX request on pre-defined interval. Minimum interval is 5 sec and default is 60 sec.

137 : In how many ways you can invoke Controllers / Controller Extensions method from VF?
Ans : Javascript Remoting, ActionFunction, ActionSupport, ActionPoller.

138 : What is the use of apex:detail component ?
Ans : With the help of this Visualforce component, we can diretly get complete behavior of page layout defined for logged in users profile. There is no need to add fields, related lists explicitly. Read more here.

139 : What is the difference between “apex:dataTable” and “apex:pageBlockTable” components in Visualforce?
Ans : Both component is used to render data in tabular format. dataTable will render records in simple HTML table format whereas the “pageBlockTable” possess default look and feel of salesforce standard CSS and must be written inside “apex:pageBlock” componet.
You can read more here.

140 : User have all the permissions to see the Dashboard and Source Folder still when he wants to see dashboard, its not visible. What might be the cause?
Ans : It is possible that Salesforce User license for Dashbaord running user is different than User wants to access Dashboard. Example – Running User license is “Salesforce” and user trying to access Dashboard is “Salesforce Plateform”.

Steps to resolve:

1. Open folder by running this text (without Quotes) in Search Explorer of Window “%USERPROFILE%\.m2″.
2. After running above command, “m2″ folder of maven will open. Now search for file (without Quotes) “*.lastUpdated”.
3. In this step, delete all the files found by running Step 2.
4. Now go to Eclipse project and select “Maven | Update Dependency” or “Maven | Update Project”.

By now, your issue will be resolved.

Happy Coding !!!

1. Log-in to the Data Loader and use the Insert function.
2. Click “Show all Salesforce objects and select “Forecasting Quota (ForecastingQuota)”.
Note: Only Data Loader version 25 and above can be used for importing Quotas in Collaborative Forecasting
3. Select the import csv file and click Next (click OK in the pop-up that shows the number of records detected in the file).

Note: The import csv file should contain the following columns:

• Currency ISO Code
• Quota Amount
• Owner ID
• Quota Month (Start Date, In Date Format)

Import Quota Using DataLoader for Forecast 3

4. Click “Create or Edit a Map”.
5. Click “Auto-Match Fields to Columns” or drag-and-drop to specify field mapping.
6. Close the mapping window and click Next.
7. Select a directory on where the error and success files will be saved.
8. Click Finish.

Note : While importing quota, on safer side, don’t select date as first of any month instead use 2nd or 3rd of month. Otherwise, it may happen that Quota of February will be inserted in month of January.

After Importing Quota, you can see in Forecast Tab for that User.

Forecast In Forcasting 3

You can see list of all supported currency by Salesforce here. (After writing this article, it might be possible that supported currencies are updated, so its suggested to visit Salesforce documentation)

For purpose of this article, i am using one manage package from AppExchange to show how it works.

Before performing any operation on installed package, just open the “Developer Console”. Once you are done, check the logs. You will see something like below screen shot and you will be able to debug at least till some level.

Salesforce like Helptext – Tooltip using JQuery

Download Salesforce Helptext like Tooltip using JQuery – Source Code

Most of the time when i override Visualforce page, customers many time demand for same Standard page layout.

apex:inputField and apex:outputField shows their help bubble (if applicable) when nested within a pageBlockSection component automatically.

If you want to provide your own text instead you can by utilizing the helpText attribute on pageBlockSectionItem. Also you can access the help text within an expression by using the respective $ObjectType global as such:

$ObjectType.Account.Fields.myField__c.inlineHelpText

However, there are scenario when we cant use pageBlockSection component. So, i came up with my own helptext CSS and javascript. For this post i am using JQuery and JQuery tooltip plugin.

First we will need to setup the OAuth permission so that our local J2EE application can interact with Salesforce. For this login to Salesforce account and Navigate to “Set up | App Set up | Develop | Remote Access” and enter the information. Be careful about the “Callback URL”. It must match in your code. After creating the “Remote Access”, note “Consumer Key” and “Consumer Secret” which will be needed in your code.

Above servlet is starting/landing servlet and authenticate your application with Salesforce using Consumer Key and Consumer Secret. After Authentication using OAuth it will call another servlet to merge PDF and save back in Salesforce.

Now, create a new Servlet which will actually read the attachment Ids from parameter and merge PDF using “iTextPDF” jar and save back again in Salesforce.

                ioe.printStackTrace();
            }
        }
    }	
}

you will also need to map the Servlet URL in “web.xml” file, which you can find in source code attached.
To run above application, enter this URL in address bar “https://localhost:8443/PDFMerge_J2EE/“.

After running above code, first time it will ask you to enter the username and password of salesforce account to allow access to your local application and then it will get all the attachments specified in code and after merging it will again attach it to parent id passed in parameter.

jar files needed to run above code:

• commons-codec-1.1.jar
• commons-codec-1.6.jar
• commons-lang3-3.1.jar
• commons-lang3-3.1-javadoc.jar
• commons-lang3-3.1-sources.jar
• commons-lang3-3.1-tests.jar
• commons-logging-1.1.1.jar
• fluent-hc-4.2.1.jar
• httpclient-4.2.1.jar
• httpclient-cache-4.2.1.jar
• httpcore-4.2.1.jar
• httpmime-4.2.1.jar
• itextpdf-5.1.0.jar

Also, please note that Salesforce OAuth can be run only on “https” protocol. Below articles are also recommended to read :

In this article, i will explain in detail on how to use Data Loader from command line.

The most important part of setting up Command line Data loader is to generate the encrypted password using utility provided by the Data Loader.

Commandline Data Loader tools

This directory contains two utility batch file : “encrypt.bat” and “process.bat”

Navigate to “Program Files | Data Loader | bin” in command prompt and run command.

encrypt.bat –g YOURSECRETKEY

Commandline Data Loader generate Secret key

The secrete key provided can be anything of your choice. Copy the generated Text and paste in new file “Key.txt”.

Now run again above command to generated encrypted password with following command:

encrypt.bat -e password "C:\Users\shiva\Desktop\Data Loader Documents\Try\Key.txt"

Commandline Data Loader generate Encrypted Password

Now, note this password somewhere, as it is going to be used in remaining part of configuration.
If you are using proxy server and it uses the password, then repeat same step for generating encrypted password.

Create file – “config.properties” :

This file contains all the common configurations settings like UserName, encrypted password. This file can also be kept as blank however it is good practice to write all common configurations in this file. Keys in this file will be same as of “Process-config.xml” as described at the end of this article.

Example:

#Loader Config
#Wed Sep 19 2012
sfdc.debugMessages=true
process.encryptionKeyFile=C:\\Users\\shiva\\Desktop\\Data Loader Documents\\Try\\Key.txt
sfdc.debugMessagesFile = C:\\Users\\shiva\\Desktop\\Data Loader Documents\\Try\\AccountExport.log
sfdc.endpoint=https://login.salesforce.com
sfdc.username=ilovenagpur@gmail.com
sfdc.password=7b5693f0cad856dc778d4b8506f2c976
sfdc.proxyUsername=proxyUserName
sfdc.proxyPassword=encrypytesPassword
sfdc.proxyHost=proxyhostName
sfdc.proxyPort=123
sfdc.loadBatchSize=200
sfdc.timeoutSecs=600

Create file – “process-conf.xml” :

This file contains all the information regarding import or export. In this article I am exporting the Account data, so sample file is

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="Account"
	class="com.salesforce.dataloader.process.ProcessRunner"
	singleton="false">
		<description>Export Account Data</description>
		<property name="name" value="Account"/>
		<property name="configOverrideMap">
		<map>
			<entry key="sfdc.enableLastRunOutput" value="false"/>
			<entry key="sfdc.entity" value="Account"/>
			<entry key="process.operation" value="extract"/>
			<entry key="sfdc.extractionRequestSize" value="500"/>
			<entry key="sfdc.extractionSOQL" value="SELECT Id FROM Account"/>
			<entry key="dataAccess.name" value="D:\Data Load\Seed Data\NPower Production - 16 Aug 12\AccountExport.csv"/>
			<entry key="dataAccess.type" value="csvWrite"/>
			<entry key="dataAccess.writeUTF8" value="true" />
		</map>
		</property>
	</bean>
</beans>

At the end of this article, you can see the description of all parameters. Assuming that we are inside the bin folder of dataloader then run below Command:

Process.bat “directory path where we have file process-config.xml”  process Name

In our case the process name is Account, process name is nothing but the property “name”.

Run Commandline Data Loader

After running the above command your data will be exported in file provided in configuration “process-config.xml” file.

While working with command line dataloader, there are chances that you get few error. So i am also inclusing few common error and there solutions:

Error 1:
Dataloader error: “javax.crypto.BadPaddingException:”Or error loading parameter of sfdc.password
Solution :
Add “process.encryptionKeyFile=C:\\Users\\315447\\Desktop\\Data Loader\\key.txt” Either in “config.properties” or “process-conf.xml”

Error 2:
Error in query: query is empty
Solution:
Occurs, If “sfdc.extractionSOQL” key in beans node does not have valid SOQL.

Parameters for Process-config.xml:

Parameter	Description
<bean id="PROCESSNAME" class="com.salesforce.lexiloader.process.ProcessRunner" singleton="false">	This first line uniquely defines the process in the XML file. This has to be unique and will be used to call the process later on. Only change the PROCESSNAME and leave all other parts the same.

So, in this article i will extend the previous one by showing how to connect git using “SSH” protocol. In this article i am referring Unfuddle.com

We will need to generate the private key (RSA) which will be unique and locked with the help of secret passphrase.

In Eclipse, Navigate to “Windows | Preferences | General | Network Connections | SSH2”.

Configure Push for SSH Authentication in Git

Click on button “Generate RSA Key” and after that provide secret Passphrase (dont forget this passphrase), now save the “private key”, if possible in “.ssh” folder which is located at “C:\Users\UseName\.ssh”.

For SSH login, let’s take example of “Unfuddle”, where we need to connect to Git using SSH protocol.

In Unfuddle, navigate to “Personal Setting” and at the bottom of page you will find option to add “public Keys”. Copy the key generated in above screen and paste it in Unfuddle personal Setting.

Follow all steps of setting up Git as per previous article.

The only change we need to configure is while setting up Push or fetch URLs.

Configure Push for SSH Authentication in Git

As you can see in above image, we have used the protocol “SSH” instead of “https” as compared to our last article.

I hope, it will help many users to set up Git for Salesforce using eclipse in case they need “SSH” authentication.

121 : Consider we have overall 90% code coverage however there is one class which have 0% code coverage. Can we still able to deploy that class on production?
Ans : Yes. Minimum 1% required for every trigger and there is no such restriction for Apex class.

122 : How to get selected records ID from List View using Javascript / Ajax Toolkit, when custom button is added on List View page?
Ans : Create a new Button on Lead of type List Button. Add the button on Lead List View Layout and write below Javascript code:

{!RequireScript("/js/functions.js")}

var recordsSelected = {!GetRecordIds($ObjectType.Lead)}
for(var i=0; i < recordsSelected .length ; i++) {
     alert('Selected ID '+recordsSelected[i]);
}

123 : In Ajax toolkit for custom Javascript button, you have to explicitly login to API because global Session variable is not available. In that case it is security vulnerable because anybody logged in can see the javascript code and your username and password. So is there any way to avoid this?
Ans: We can create a visualforce page with output type as JavaScript. Global session variable is available in VF page. Initialize the global javascript variable in that VF page. include VF page as a javascript file and we are done!

124 : In Custom Component How we can return value to Custom Controller or Controller Extension?
Ans: In Apex, Objects are passed by reference (read this article to understand Pass by Value and Pass by reference in Salesforce and also read this Salesforce blog article). So supply an argument of wrapper class (object) type to custom component. If its value is changed in Custom component we will get updated value in controller also.

125 : Lets consider you had created outbound changeset previously. After that, some class is modified which is part of that old changeset. If you clone that Changeset, current updated class will be included or that previous class will be included in changset?
Ans : Once changeset is created it cannot be modified. After creation of changset, if we modify any component it will not reflected and when we clone the changeset, all components (offcource old copy of component) will be added to changeset.

126 : We have a “Time Based Workflow” and there is Action scheduled to be executed. If we Deactivate the workflow, Scheduled actions will be removed from queue or not?
Ans : Even after deactivation of workflow, its action will be active in queue.

127 : We have “Time Based Workflow” and there is action scheduled to be executed. Can we delete that workflow?
Ans : If a workflow have any pending time dependent action, then we cannot delete the workflow.

128 : How to clear the Time based workflow action queue ?
Ans : Two ways to achieve this : 1. Make criteria false for all those records. 2. Navigate to “Set up | Monitoring | Time Based Workflow”, search for scheduled actions and remove from queue.

129 : While creating workflow on Task, what difference observed on available actions?
Ans : “Send Email” action is not available while creating workflow on task.

130 : In trigger, lets say we have system.debug() statement after adderror() method. Will system.debug() be statement executed in Trigger after adderror() method?
Ans: adderror() method is not error statement rather its normal execution flow and all the statements written after adderror() will be executed normally.

Year Range in Salesforce Date Picker

So, lets start to resolve this problem. The only thing we will need is Javascript based Home page Component.
Navigate to “Set up | App SetUp | Customize | Home | Home Page Components”.
click on “New” Custom Component. In Next screen you will prompted with the type of Homepage component.

Homepage Component Type in Salesforce

Select “HTML Area”.
In Next screen, click on checkbox “Show HTML” as shown in below image.

Javascript code in Home Page component – Salesforce

Now write below Javascript code in HTML area :

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
<span id="hideThisHomePageComp"></span>
<script type="text/javascript">
$j = jQuery.noConflict();
$j(document).ready(function() {
                var startYear=1985;
                var endYear=2024;
                var htmlStr='';
                if(startYear<endYear){
                                for(i=startYear;i<endYear+1;i++){
                                                htmlStr += "<option value=\""+i+"\">"+i+"</option>";
                                }
                                $j('#calYearPicker').html(htmlStr);
                }
                $j('#sidebarDiv #hideThisHomePageComp').parent().parent().hide();
                }
);
</script>

Note:

• While importing JQuery from Google or any other CDN, don’t write “http” protocol. It will automatically detect the protocol.
• Don’t write any single line comment, as Salesforce will internally convert above Javascript code into single line. And if you write any single line comment then everything after that will be commented. Multiple line comment will work.
• If you are using Datepicker in custom Visualforce page and if sidebar is not enabled then above work around will not work.
• We are hiding the home page component itself by line “parent().parent().hide()”, as there is no need to show this component to end user.

Era of Git

Git has emerged as the most powerful source code repository and widely accepted by the developer communities. If I will talk about Git this article is going to be out of discussion scope.

Architecture of GIT

Above figure describes Architect of Git. The one thing to notice in above figure is that Git has local repository as well as remote repository which make it better and more flexible than any other code repository tool.

Remote and Local Repository in GIT

As you can see in above diagram also, user can work on completely different branch which is stored on his local repository and when he thinks that he is ready to push the code on Git, just commit the changes on remote repository.

Step 1:
So, let’s start with using Git with Salesforce using Eclipse plug-in EGit.

EGit is an Eclipse Team provider for the distributed version control system Git. EGit allows performing Git commands from the Eclipse IDE.

EGit is based on the JGit library. JGit is a library which implements the Git functionality in Java.
Most Eclipse 4.2 packages from Eclipse.org contain EGit in there default configuration. In this case no additional installation is required.

If EGit is missing in your Eclipse installation, you can install it via the Eclipse Update Manager via: Help ?Install new Software. EGit can be installed from the following URL: http://download.eclipse.org/egit/updates

Step 2:
Gets the Salesforce code in local workspace using force.com IDE.

Step 3:
Now, it is the time to configure repository on your local system which is also known as “Local Repository”. Navigate to “Right click on Project | Team | Share Project”

Share Salesforce Project in Eclipse

On the basis of your eclipse configuration, you will get options like CVS, Git, SVN etc. Select “Git” and click on Next button.

Step 4:
Click on “create” button as shown in below image

Configure Git Repository in Eclipse

A new pop up will open where we can give Local repository name as well as location where we want to save the local repository. In this article, I am using the name “GITDemo” name. Now click on Finish button.

Non Indexed Local GIT Repository

If you check the Salesforce project, the folder will look something like above image with questions marks (“?”) on folders. Question marks means Git does not know what to do with files, either you can schedule them for commit or add few of them in ignore list (means they will not saved in Git).

Step 5:
Now we will commit our files and folder in Local repository. Before commit we have to mention that which files and folder should be committed and ignored. In this case I am adding complete salesforce directory for commit. To do this, write click on “Project | Team | Add to Index”. After this operation your icons should be something like below image:

Indexed but Non Committed changes in GIT – Eclipse – Salesforce

It’s time to commit all indexed files and folders in local repository. Again navigate to “Project | Team | Commit”. New Popup window will appear and ask for comment. It is mandatory to provide meaningful comment for each commit as it will be very easy for diagnosis in case needed in future.

Commit Changes to Git Repository – Eclipse – Salesforce

After commit the folder structure will appear with following icons:

Committed folders in Salesforce Eclipse using Git

Step 6:
Until here, we have done configuration for Local repository. Let’s move on to create a remote repository. There are lots of options available for hosting your code which supports Git. Few of them are

1. GitHub
2. BitBucket
3. Unfuddle

Choice is up to us, which depends on license cost and many other factors. For demo, I am using the “BitBucket”.

Create a free new account at “BitBucket” and create a repository. After successful creation of Git repository you will get the URL for your repository. There will be two URL provided, https and SSH.
For this demo, I am using https URL. The URL format will be something like

https://YOURUSERNAME@bitbucket.org/YOURUSERNAME/YOUR_REPOSITORY_Name.git

In Eclipse, at upper right corner, change the perspective to “Git Repository Exploring” as shown in below image.

Git Repository Perspective in Eclipse

You will get the list of all Local Repository in this perspective. Now in Remotes, right click to create new Remote as shown in below image.

Create Remote Git Repository Eclipse for Salesforce

One new popup will appear like below

Git Create New Remote in Eclipse – Salesforce

First select the option “Push” and give name of remote repository Name. “Push” means you are going to save changes on remote repository and “Fetch” means you are going to fetch code from remote repository.
When you will click on Ok button new window will open.

Configure Push for remote repository – Git – Eclipse – Salesforce

In new window click on “Change” (1) button as shown in above image. Again new pop up window will open. At location 2 provide your complete Git https URL. At location 3 provide your username and password. Don’t forget to check the box at location 4 which says “Store in Secure Store”. Now click on Finish Button.

Git Ref Mappings – Eclipse – Salesforce

On Parent window click on Add (1) button. In new window, in Local branch text box and Remote branch enter “refs/heads/master” or you can press “Ctrl + Space Bar”.

After everything, click on “Dry-run” button to check, whether everything is properly configured or not? If everything is properly configured then it will show the repository name else it will show the error message.

Now click on “Save and Push” button to move changes from local repository to remote repository.

In the same way you can configure “fetch” to get the code from remote repository.

I hope it will be help full for learners. I am waiting for your feedback. In next article I will show how to connect using SSH instead of https protocol.

Map<String, Schema.SObjectType> m  = Schema.getGlobalDescribe() ;
Schema.SObjectType s = m.get('API_Name_Of_SObject') ;
Schema.DescribeSObjectResult cfrSchema = s.getDescribe() ;
Map<String,Schema.RecordTypeInfo> RecordTypeInfo = cfrSchema.getRecordTypeInfosByName();
Id rtId = RecordTypeInfo.get('Record Type Name').getRecordTypeId();

112 : Write Apex code which will take the RecordID as input and on the basis of that it will print the Object name and field names of sObject.
Ans:

List<Schema.SObjectType> gd = Schema.getGlobalDescribe().Values();
Map<String,String> objectMap = new Map<String,String>();
for(Schema.SObjectType f : gd)
{
     objectMap.put(f.getDescribe().getKeyPrefix(), f.getDescribe().getName());
}

String sampleId ='00390000003LIVw';
String prefix =  sampleId.substring(0,3);
String objectName = objectMap.get(prefix);
System.debug('** SObject Name ** '+objectName);

Map<String, Schema.SObjectField> desResult = Schema.getGlobalDescribe().get(objectName).getDescribe().Fields.getMap();
List<String> fieldList = new List<String>();
fieldList.addAll(desResult.keySet());
for(integer i =0;i<fieldList.size();i++)
{
    System.debug('** Field Name ** '+fieldList[i]);
}

113. Consider a scenario where you have created a Visualforce page and Controller. You want to restrict the controller action for users which are logged in using “Grant Login Access”. How to acheive this?

Ans:

When System admin logged in on the behalf of any other user. On upper right corner message is displayed that user is logged-in on behalf of some other user. In Visualforce page we can search for the element with class name present or not? If the element with that Class name exist means logged-in user is not a actual user.

114. How to get “https” link instead of “http” for Visualforce page using URLFOR() in Email Template ?
Ans: When you create the Link using URLFOR() in Email Template, it creates link in “http” format instead of “https” and thus causes end user to logged into salesforce again.

So instead of

<a href='{!URLFOR('/apex/SomePage', null, [id=Some_Object__c.Id,retURL="/apex/SomeOtherPage"])}'>Go to SomePage here!</a>

We can use something like :

<a href='{!SUBSTITUTE(URLFOR('/apex/SomePage', null, [id=Some_Object__c.Id,retURL="/apex/SomeOtherPage"]),'http:','https:')}'>Go to SomePage here!</a>

115. What is the best way to check whether organization have PersonAccount enable or not using Apex?
Ans:

Method 1:

// Test to see if person accounts are enabled.
public Boolean personAccountsEnabled()
{
    try
    {
        // Try to use the isPersonAccount field.
        sObject testObject = new Account();
        testObject.get( 'isPersonAccount' );
        // If we got here without an exception, return true.
        return true;
    }
    catch( Exception ex )
    {
        // An exception was generated trying to access the isPersonAccount field
        // so person accounts aren't enabled; return false.
        return false;
    }
}

Method 2:

// Check to see if person accounts are enabled.
public Boolean personAccountsEnabled()
{
    // Describe the Account object to get a map of all fields
    // then check to see if the map contains the field 'isPersonAccount'
    return Schema.sObjectType.Account.fields.getMap().containsKey( 'isPersonAccount' );
}

116 : When you get the error “Non-selective query against large object type”? how to resolve it?
Ans : Whenever an object has greater than 100K records any query on that object must be “selective”. For a query to be selective it must have enough indexed filters (where clauses) so that less than 10% of the records (in our example 10K) are returned before applying the limit statement.

117 : How to get the debug log of Connection user in salesforce to salesforce Integration?
Ans : When configuring Debug Logs, you cannot choose a Salesforce to Salesforce Connection User from the User Lookup, but there is a workaround to

achieve this.

To begin capturing Debug Logs for a Connection User open the following URL in your browser:

https://XXX.salesforce.com/p/setup/layout/AddApexDebugLogUser?retURL=%2Fsetup%2Fui%2FlistApexTraces.apexp&UserLookupInput_lkid=YYYYYYYYYYYYYY
&UserLookupInput=Connection%20User

Replace XXX with your salesforce instance, UserLookupInput_lkid is the ID of the Connection User and UserLookupInput is the User name. You can find

the user ID of the connection user, by inspecting the CreatedById for a record created by this user. (eg. via eclipse or Force.com explorer)

118 : In Controller extension, you are getting the error “SObject row was retrieved via SOQL without querying the requested field” while accessing the field of parent Custom Object or standard Object for which the Controller extension was written. How to resolve that?
Ans : In Constructor of the Controller extension, only Id of Custom Object is supplied. We need to query all the required field explicitly in order to use in remaining part of the code.

119: Using Apex how you can determine that user is in Sandbox or production?
Ans : read this URL for answer

120: Can you use aggregate expressions inside inner query?
Explanation – Can you use Group by clause inside inner query in SOQL?
Example : Something like :

 SELECT Id, Name,(SELECT Count(Id),Name FROM Contacts Group By Name Having count(Id) > 1 ) FROM Account

Ans:  No. only root queries support aggregate expressions. Return type is List<AggregateResult> for above query However the root result expects List<Account> and there is no syntax or provision available in Salesforce to specify that child results are of type “AggregateResult“.

Step 1:

Run tool “Keytool” provided by the JRE to create a “keystore file”.
The command to run tool is:

keytool -genkey -alias tomcat -keyalg RSA -keystore D:/.keyStore

Where “D:/.keystore” is the path where file should be created.
Instead of alias “tomcat” any other name can be used.
After running above command, you will be asked many questions, so answer them correctly as shown in below image:

Tomcat SSL keytool to create keystore file

Remember the password provided, as it will be needed in next step.

Step 2:

Now, in next step go to “conf” folder of tomcat, and open file “server.xml”.
There you will find lines of code something like:

<-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 -->
<!--
<Connector
           port="8443" minProcessors="5" maxProcessors="75"
           enableLookups="true" disableUploadTimeout="true"
           acceptCount="100" debug="0" scheme="https" secure="true";
           clientAuth="false" sslProtocol="TLS"/>
-->

So, to enable the SSL, uncomment above code and tweek like below:

<Connector
	protocol="org.apache.coyote.http11.Http11Protocol"
	port="8443" maxHttpHeaderSize="8192"
    maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
    enableLookups="true" disableUploadTimeout="true"
    acceptCount="100" scheme="https" secure="true"
    clientAuth="false" sslProtocol="TLS"
	keystoreFile="F:\eclipse\Frameworks\apache-tomcat-5.5.31 - SSL Configured\.keyStore"
	keystorePass="YOURpwd"/>

As you can see, I have added few more attributes like:

Protocol : If the APR (Apache Portable Runtime) is enabled in tomcat (maximum time it is enabled by default), then this approach will not work. so configure tomcat that we want to use Java (JSSE) connector, regardless of whether the APR library is loaded or not.
keystoreFile : Full path of the keystore file creates in step 1.
keystorePass: Password used while creating file in step1.

After these changes, save Server.xml and navigate to: https://localhost:8443/ , As you can see in below image, SSL is enabled.

https protocol in Tomcat – SSL Enabled

Now, as you can see, although we have created SSL certificate for local server, browser is showing that it is not secured.

SSL verifies the authenticity of a site’s certificate by using something called a “chain of trust,” which basically means that during the handshake, SSL initiates an additional handshake with the Certificate Authority (CA) specified in your site’s certificate, to verify that you haven’t simply made up your own CA (Which actually we have done in our case ).

If you want to remove error, you have to get certificate from some Certificate Authority so that during handshake, accuracy of your certificate can be validated.
If you have valid certificates then please read this article.
