Multiple address on Visualforce Page with GMAP in apex salesforce

2012-06-07T00:16:00.003-07:00

Hi guys ,

Look at standard visualforce page for showing multiple address on Gmap.

<apex:page standardController="Account" sidebar="false">
<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=ABQIAAAAzr2EBOXUKnm_jVnk0OJI7xSosDVG8KKPE1-m51RBrvYughuyMxQ-i1QfUnH94QxWIa6N4U6MouMmBA&sensor=false" type="text/javascript"></script>

Calculate Hour Minute In Apex Salesforce

2012-05-29T04:45:00.000-07:00

Hi ,

As I had gone to search that how to separate hour and minute in apex , I was trying to search any method which could be return after decimal value so that I could calculate all values after decimal place as total number of minute and then extract the hour from total number of minute divide by 60 and separate again hour and minute !

Then I wrote some logic which is explained below !

We have a class contains two methods returnCheckDecimalValueForMin(string val) and returnCheckDecimalValueForHour(string hour) .

public class className {

public string returnCheckDecimalValueForMin(string dayVal){                      
                string[] ss = new string[]{};
                if(dayVal !='' && dayVal!=null){
                        if(dayVal.contains('.')){                         
                         string sss = dayVal.replace('.',',');
                         ss = sss.split(',');              
                         return ss[1] ;                                         
                        }else {
                                return dayVal ;
                        }
                        if(ss.size()>0){
                                return ss[1];
                        }else {return '';}
                }else { return '';}                                           
        }
       
        public string returnCheckDecimalValueForHour(string dayVal){
                string[] ss = new string[]{};
                if(dayVal !='' && dayVal!=null){
                        if(dayVal.contains('.')){                         
                         string sss = dayVal.replace('.',',');
                         ss = sss.split(',');           
                         return ss[0] ;                                                   
                        }else {                                
                                return dayVal ;
                        }                      
                }else { return '';}                                    
        }
}

Now let say we have a list of decimal values like 34.46 , 34.56 , 45.57

so what we need to do actually to separate

34+34+45 =   113

46+56+67 =  169

integer i = math.mod(169,60);

integer returnHr = 169/60 ;

Integer TotalHours = 113 + returnHr.intvalue();

Integer remainingMinutes = 169 - 60*returnHr.intvalue() ;

User Photo Not Visible On Force.com Site From Rest API In Apex Salesforce

2012-05-25T21:11:00.001-07:00

Hi All ,
I was accessing the photourl through force.com site !

"photo": {
        "largePhotoUrl": "https://instance_name/profilephoto/729D00000000BDV/F",
        "photoVersionId": "729D00000000BDV",
        "smallPhotoUrl": "https://instance_name/profilephoto/729D00000000BDV/T"
},

Now if we expose these photo url on visualforce page would render properly but if we try to get the same of public force.com site these photo url does not exist because session does not maintain .Images look like burst and does not show properly. So what we can do , we can append either oauth_token or sessionid at the last of the photourl as a parameter. Let say our photo url is "largePhotoUrl":

"https://instance_name/profilephoto/729D00000000BDV/F",

so we need to append the oauth_token like :

largePhotoUrl": "https://instance_name/profilephoto/729D00000000BDV/F'?oauth_token=00DV0000004RJpB!ARMAQFwrXxu7t6DAjWcseeWxXTo9UtSh4xZbrWJqHRnCulQ16yKqq97wIWIREdPtKfQ7BcFffyD9Y43MVBfa4hmHaPLfkT6C';

Now you can access the image as public with the help of oauth_token . Thanks

Product And Campaign Tab Not Visible For Partner Portal Tab In apex Salesforce

2012-05-23T23:15:00.001-07:00

Hi ,
Very first think you need to check that Customize Portal Tab for partner portal if any of the tab is not available in the left or right drop down then its mean those tabs are not available for portal user .

We have alternate option to do the same that we can create a simple VF page with the standard controller of that particular object and redirected page url to the url comes when clicking on product or Campaign Tab generally .

Below is example for product tab :

VF Page :

<apex:page standardController="Product2" extensions="ProductTabCls" action="{!ProductRrl}">


</apex:page>

Class Code :

public class ProductTabCls {

    public ProductTabCls(ApexPages.StandardController controller) {

    }   

    public pagereference ProductRrl(){

        pagereference page = new pagereference('/01t/o');

        page.setRedirect(true);

        return page;

    }   

}

Now Create a Visualforce Tab by selecting the newly created VF page !

visualforce dynamicComponent in apex salesforce

2012-03-23T03:59:00.000-07:00

Hi all ,
This post is regarding the Visualforce Tag <apex:dynamicComponent> which is very useful feature in Visuaforce developement.
Hava a look on this.

This tag acts as a placeholder for your dynamic Apex components. It has one required parameter componentValue which accepts the name of an Apex method that returns a dynamic component.

Page:
====

<apex:page standardController="Contact" extensions="dynamicSample">
   <apex:dynamicComponent componentValue="{!headerWithDueDateCheck}"/>
   <apex:form >
        <apex:inputField value="{!Contact.LastName}"/>
        <apex:commandButton value="Save" action="{!save}"/>
    </apex:form>
  
     <apex:pageBlock title="This is dynamic Page Block Table">
     <!--<apex:pageBlockTable ></apex:pageBlockTable>-->
       <apex:dynamicComponent componentValue="{!PageBlockDate}"/>
     </apex:pageBlock>
 
</apex:page>

Class Code: ========

public class dynamicSample {

    public dynamicSample(ApexPages.StandardController controller) {
      
        public Component.Apex.PageBlockTable getPageBlockDate(){
            List<Contact> lstContact = [select id,Name,FirstName,LastName from Contact];
            Component.Apex.PageBlockTable pbTable = new Component.Apex.PageBlockTable();
            pbTable.value = lstContact ;
            pbTable.var = 'x';
            pbTable.columns =3;
            pbTable.border= '10' ;           
            Component.Apex.Column firstNameCol = new Component.Apex.Column();
            firstNameCol.expressions.value = '{!x.FirstName}';
            Component.Apex.Column firstNameCol1 = new Component.Apex.Column();
            firstNameCol1.expressions.value = '{!x.Id}';
            pbTable.childComponents.add(firstNameCol);
            pbTable.childComponents.add(firstNameCol1);
            return pbTable;
        }
  
        public Component.Apex.SectionHeader getHeaderWithDueDateCheck() {
        date dueDate = date.newInstance(2011, 7, 4);
        boolean overdue = date.today().daysBetween(dueDate) < 0;

        Component.Apex.SectionHeader sectionHeader = new Component.Apex.SectionHeader();
        if (overdue) {
            sectionHeader.title = 'This Form Was Due On ' + dueDate.format() + '!';
            return sectionHeader;
        } else {
            sectionHeader.title = 'Form Submission';
            return sectionHeader;
        }
    }
}

Record type for creating test class data in Apex Salesforce

2012-03-20T21:27:00.001-07:00

Hello guys ,
We have some important consideration while creating test data in our test classes.
So let say if we need to create a record based on the record type id , what we do normally , we query on record type object based on SobjectType and the record type Name.
for example :
let say we have a Account Record Types A & B Not if we need to create a Account Record with record type A or B . We normally query like this .

RecordType rt = [select id,Name from RecordType where SobjectType='Account' and Name='A' Limit 1];

And now use this value further while creating the Account Record.

Account acc = new Account(Name='Test' , recordTypeId=rt.id);

To avoid this query in test class we can the same in some other manner .

Schema.DescribeSObjectResult cfrSchema = Schema.SObjectType.Account; 
Map<String,Schema.RecordTypeInfo> AccountRecordTypeInfo = cfrSchema.getRecordTypeInfosByName();

Now to get the recordTypeId we will have to use a method getRecordTypeId.

Id rtId = AccountRecordTypeInfo .get('A').getRecordTypeId(),

Now Use can insert Account Record like

Account Acc = new Account(Name='test',recordtypeid=AccountRecordTypeInfo .get('A').getRecordTypeId());
insert Acc;

Thanks

Export Data in CSV or Excel In Apex Salesforce

2012-03-13T00:08:00.001-07:00

Hello guys ,
This articles lets you know how to export data in csv or excel.

See Example Below .
Copy paste code according to your data structure.

For Excel :
Note : Make sure if you are on MAC then do not use pageBlock and pageBlockTable other wise you get an issue with extra content on visualforce page like if(!window.sfdcPage){ window.sfdcPage = new ApexPage(); }
So to avoid this issue just use DataTable instead of pageBlock and PageBlockTable.

<apex:page controller="exportExcel" action="{!exportToExcel}" readOnly="true" contentType="application/vnd.ms-excel#ConsignmentSearchData.xls">

    
    <apex:pageBlock >
        <apex:pageBlockTable value="{!lstwrapper}" var="x">
           <apex:column headerValue="shipTo">
                {!x.shipTo}
            </apex:column>
             <apex:column headerValue="searchNumber">
                {!x.searchNumber}
            </apex:column>
             <apex:column headerValue="accountName">
                {!x.accountName}
            </apex:column>
             <apex:column headerValue="businessUnit">
                {!x.businessUnit}

                {!x.expirationDate}
            </apex:column>
             <apex:column headerValue="expirationEndDate">
                {!x.expirationEndDate}
            </apex:column>
            <apex:column headerValue="expirationStartDate">

                {!x.invoiceNumber}
            </apex:column>
        </apex:pageBlockTable>
    </apex:pageBlock>

Remove Attachment Button From Attachment Related List in salesforce

2012-02-16T03:32:00.000-08:00

Hi Guys ,
We can remove attach button from Notes And Attachment Related List from any object by creating a visualforce page.
Create a visualforce page RemoveAttachBTN with object standard controller .

<apex:page standardController="Account">       
<apex:relatedList list="NotesAndAttachments">
  <apex:facet name="header">&nbsp;</apex:facet>    <!--This line of code removing the attachment header-->        
 </apex:relatedList>
</apex:page>

https://ap1.visual.force.com/apex/RemoveAttachBTN?id=RecordIdofStandardController

Now go to the Edit Layout of the record and add this visualforce page by creating any section , the only drawback is that this section would be between Standard Button of page layout . We can put visualforce just like related list of record.

Dynamic Visualforce Page In Apex Salesforce

2011-11-30T23:46:00.001-08:00

Hi Guys ,
We can create Visualforce Pages dynamically . Just need to write the script in Apex Class and avoiding on Visualforce Page.

Here I am just creating a list of string with the Account Object Fields with their API name and passing this on Visualforce page .

Controller : =======

public class DynamicPage{

    public DynamicPage(ApexPages.StandardController controller) {
  
    }
  
    public Account acc {get;set;}
    public List<String> threeFieldList {
    get {
        if (threeFieldList == null) {
            threeFieldList = new List<String>();
            threeFieldList.add('Industry');
            threeFieldList.add('AnnualRevenue');
            threeFieldList.add('BillingCity')
        }
        return threeFieldList;
        }
        private set;
    }
 }

Page Code : =======

<apex:page standardController="Account" extensions="DynamicPage">

<apex:form >
    <apex:pageBlock title="Binding Input Field Dynamically" mode="edit">
        <apex:pageBlockSection columns="1">
                <apex:inputField value="{!Account.Name}" />
                    <apex:repeat value="{!threeFieldList}" var="afield" >
                        <apex:inputField value="{!acc[afield]}" />
                    </apex:repeat>
        </apex:pageBlockSection>
    </apex:pageBlock>
</apex:form>

</apex:page>

So when we need to add another field just need to add that field API Name in threeFieldList which passing in repeater.

           break;
        } else if (reader.getEventType() == XmlTag.CHARACTERS) {
           //book.name = reader.getText();
           book.name = getDecodedString(reader);
        }
        reader.next();
     }
     return book;
   }

  
   public XmlStreamReaderDemo(string data){
        XmlStreamReader xsr = new XmlStreamReader(data);
        listRecords = parseBooks(xsr);
    }
   
    public void testBookParser() {
     String str = '<books><book author="Chatty">Foo bar</book>' +
        '<book author="Sassy">Baz</book></books>';
     XmlStreamReaderDemo callxml1 = new XmlStreamReaderDemo(str);
     system.debug('callxml1 callxml1 :'+callxml1);
     List<Lead> leadtoInsert = new List<Lead>();
     for(XmlStreamReaderDemo.Book b : callxml1.listRecords) {           
           Lead Ld = new Lead();
           ld.Company = 'x';
           ld.LastName = b.name;
           leadtoInsert.add(ld);         
        }
        system.debug('*********** ::: '+leadtoInsert.size());
        system.debug('*********** ::: '+leadtoInsert);
        if(leadtoInsert.size() >0){
       insert leadtoInsert;
   }
   }
  
     String getDecodedString(Xmlstreamreader reader)
      {
        return EncodingUtil.urlDecode(reader.getText(), 'UTF-8').trim();
      }
}

Use Anonymous Block to execute this code :

XmlStreamReaderDemo  obj = new XmlStreamReaderDemo ( '<books><book author="Chatty">Foo bar</book>' +
        '<book author="Sassy">Baz</book></books>');
obj.testBookParser();

Now you will see two Lead records have been inserted.

Visual Workflow In salesforce apex

2011-10-07T06:10:00.000-07:00

Hello Guys ,
We have some pretty much interesting topic in salesforce its Visual Workflow.

Visual Workflow:

Flows represent your business processes and run in your Salesforce organization as rule-based applications.Flows are built in a graphical interface and require no programing skills.They can be built quickly and are easily maintained.

With Visual Workflow you can outline and manage procedures such as approval processes, interviews, or call center questionnaires.

For better understanding just download the pdf in which steps are clearly defined to make better understanding and implementation.

Just go to Salesforce PDFs Tab on start of the page and Click on Visual Workflow Book.

Must implement the topic its just 30 min task.

New Release Winter 12 In Apex Salesforce

2011-10-03T03:09:00.000-07:00

Hello folks,
We have some new important features in Winter 12 Release.

1. Read Only Mode :
By default, Visualforce pages have a limit of 50,000 records that can be queried in a single request, and iteration components such as <apex:pageBlockTable> are limited to 1,000 iterations. For pages that do not need to modify data, you can now enable read-only mode for the page, using the new readOnly attribute :

<apex:page controller="SummaryStatsController" readOnly="true">

      <p>Here is a statistic: {!veryLargeSummaryStat}</p>

</apex:page>

Setting a page to read-only mode relaxes the query limit to 1 million rows, allowing you to work with much large of data. It also expands the iteration limit to 10,000 iterations.

2. label attribute for input components :

Support for overriding the default form field label has been added to <apex:inputField>. With this change, all form input components support this attribute.

3. tabOrderHint attribute for <apex:inputField>

Another change for <apex:inputField> is the addition of the tabOrderHint attribute. This attribute lets you
specify the relative order of form fields on a page, for the purposes of tabbing through the form. It does not allow youto specify the actual value of a field's tabIndex HTML attribute. Instead, Visualforce uses the tabOrderHint to calculate an appropriate HTML tabIndex for the field.

tabOrderHint is not supported inside iteration components like <apex:pageBlockTable> or <apex:dataList>.
tabOrderHint is not currently available for input components other than <apex:inputField>. Other input
components like <apex:inputText> can use the tabIndex attribute instead.

4. Package Install Improvements : New IsTest(OnInstall=true) Annotation

Using the IsTest(OnInstall=true) annotation, you can control which Apex tests are executed during package installation. This annotation is used for tests in managed or unmanaged packages. Test methods with this annotation, or methods that are part of a test class that has this annotation, will always be executed during package installation. Tests annotated to run duringpackage installation must pass in order for the package installation to succeed. It is no longer possible to bypass a failing test. during package installation. A test method or a class that doesn't have this annotation, or that is annotated with isTest(OnInstall=false) or isTest, won't be executed during installation.
This annotation applies only to packages uploaded in Winter '12 or later. Packages uploaded prior to Winter '12 aren't yet affected by this annotation and all their tests run during installation.

Note: Starting with Spring '12, tests won't automatically run when a customer installs your package. If you want to run tests upon package installation, we strongly recommend that you add the @isTest(OnInstall=true)
annotation to all test classes or test methods that you want executed, and subsequently, package and release a new version of your app before Spring '12.

5.Visualforce Charting—Pilot :

The Winter '12 release has a new pilot feature, Visualforce Charting. Visualforce charting is a collection of components that provide a simple and intuitive way to create charts in your Visualforce pages and custom components. Visualforce charting gives you an easy way to create customized business charts, based on data sets that you can create directly from SOQL queries, or by building the data set in your own Apex code. By combining and configuring individual data series, you can compose charts that display your data in ways meaningful to your organization.

Charts are defined using Visualforce components, which generate JavaScript that renders the chart within the browser. Here's what a simple chart might look like:

<apex:page controller="PieChartCtlr" title="Pie Chart">

        <apex:chart data="{!pieData}">

             <apex:pieSeries labelField="name" dataField="data1"/>

         </apex:chart>

</apex:page>

Note : Contact salesforce.com to have Visualforce charting enabled for your organization.

6. New Sites Methods
The following new methods have been added to the Sites class:

• getAdminEmail: Returns the email address of the site administrator.
• getAdminId: Returns the user ID of the site administrator.

Additionally, createPortalUser now has an additional optional argument of type Boolean, which determines whether a new user email is sent to the portal user.

7.New System Methods: isBatch, isFuture, and isScheduled
The following methods have been added to the System class:
• isBatch: Determines if the currently executing code is invoked by a batch Apex job. Since a future method can't be invoked from a batch Apex job, use this method to check if the currently executing code is a batch Apex job before you invoke a future method.

• isFuture: Determines if the currently executing code is invoked by code contained in a method annotated with @future. Since a future method can't be invoked from another future method, use this method to check if the current code is executing within the context of a future method before you invoke a future method.

• isScheduled: Determines if the currently executing code is invoked by a scheduled Apex job

8.Common Test Data Creation Methods in Public Test Classes.

Classes annotated with @isTest no longer have to be private. You can now create public test classes that expose common methods for test data creation. These public methods can be called by tests outside the test class for setting up data that the tests need to run against.

Methods of a public test class can only be called from a running test, that is, a test method or code invoked by a test method, and can't be called by a non-test request.
This is an example of a public test class that contains utility methods for test data creation:

@isTest

public class TestUtil {

public static void createTestAccounts() {

// Create some test accounts

}

public static void createTestContacts() {

// Create some test contacts

}

}

9. Higher Governor Limits in Some Categories
The following governor limits are higher for Batch Apex and future methods:
• Total number of SOQL queries issued is 200 instead of 100.
• Total number of executed code statements is 1,000,000 instead of 200,000.
In addition, the heap size limit is now doubled and is raised for Batch Apex and future methods
• Total heap size is 6 MB.
• Total heap size for Batch Apex and future methods is 12 MB.

10.Method Size Limit

The size of a method is limited to 65,535 bytecode instructions in compiled form. Large methods that exceed the allowed limit cause an exception to be thrown during the execution of your code.

11. New Schema Methods
The following new method has been added to the Schema.ChildRelationship class:
• isRestrictedDelete: Returns true if the parent object can't be deleted because it is referenced by a child object, false otherwise. This prevents users from deleting any records that are part of a lookup relationship.
The following new methods have been added to the Schema.DescribeFieldResult class

• isCascadeDelete: Returns true if the child object is deleted when the parent object is deleted, false otherwise. This allows a cascade delete when a parent lookup record is deleted, allowing users to delete large numbers of records without regard for sharing or visibility constraints.

• isRestrictedDelete: Returns true if the parent object can't be deleted because it is referenced by a child object, false otherwise. This prevents users from deleting any records that are part of a lookup relationship.

12. Getting the Currency Code for Single Currency Organizations

The UserInfo getDefaultCurrency method now returns the organization's currency code for single currency
organizations.

For Apex saved using Salesforce API version 22.0 or earlier, getDefaultCurrency returns null for single currency organizations.

13. String Conversion of Number Fields

Previously, when String.valueOf was called with a field of type Number of an sObject, it incorrectly treated the number field as a Decimal when converting it to a String and used the String.valueOf(Decimal d) method to perform the conversion to a String. Apex now correctly converts a number field to a Double before performing the conversion and uses the corresponding String.valueOf(Double d) method to convert the Double value to a String. One side effect of this change is that converted String values of number fields that have no decimal fraction now have a decimal point (.0) in them where they didn't before.

14. Fix for Uncaught Exception Bug for Apex Code Saved Using Salesforce API version 20.0 or earlier

Exceptions were not being caught in the catch block under a certain condition for Apex code saved using Salesforce API version 20.0 or earlier. The exception wasn’t being caught in the catch block if the try block also threw an exception. This bug has now been fixed for all versions of Apex.

Make Select List Required On Visualforce Page in Apex Salesforce

2011-09-27T02:42:00.000-07:00

Hello guys ,
If we are creating a select list on Visualforce page its not possible to make it required by setting its attribute required="true".

So we have to alter some code in that.
For example :

<apex:selectList value="{!countries}"  multiselect="false" size="1">

            <apex:selectOptions value="{!items}"/>

</apex:selectList>

items - > list of your selected items
countries - > variable which hold the selected value.

required="true" - > Did not work in this way ..

Now I am writing some think like this..

<apex:form >



<apex:pageBlock >

        <apex:pageBlockSection >

      <apex:outputPanel styleClass="requiredInput" layout="block" id="pwPanel" >

   <apex:outputPanel styleClass="requiredBlock"/>

                    <apex:selectList value="{!countries}" multiselect="false" size="1">

                              <apex:selectOptions value="{!items}"/>

                       </apex:selectList>

    </apex:outputPanel>

        <apex:commandButton value="Test" action="{!test}" rerender="out" status="status"/>

        </apex:pageBlockSection>

        </apex:pageBlock>

    </apex:form>

Now this select list values will display as required even no need to put the required attribute.

Attach document in Attachment Object using Visualforce page in Salesforce Apex

2011-09-12T03:50:00.000-07:00

Hello folks,

We have interesting here...
Today I am going to attach the file to any object related list in attachment object.

Whole code is given below.

You just need to copy and paste this code in your visualforce page.

Note: Please ware in mind you must have an object Id in your VF page URL like

https://ap1.visual.force.com/apex/InputFileAttachment?id=AnyObjectSFDCId

It mean you are calling this VF page by sending the CurrentPage Id which would work as ParentId for the Attachment Object.

VF page:
=======

<apex:page Controller="InputFileAttachment"> 
  <apex:sectionHeader title="Attach File "/>
  <apex:form >
  <apex:pageBlock >
      <apex:pageBlockButtons >
          <apex:commandButton value="Attach New File" action="{!AttachNewFile}"/>
      </apex:pageBlockButtons>

      <apex:pageBlockSection >     
          <apex:inputFile value="{!Attach}"></apex:inputFile>         
      </apex:pageBlockSection>    
  </apex:pageBlock>
  </apex:form>
</apex:page>

Controller :
========

public class InputFileAttachment {
    public blob Attach {get;set;}  
    string CurrentId ;
  
    public InputFileAttachment ()
    {      
        CurrentId = ApexPages.CurrentPage().getParameters().get('Id');      
    }   
    public pagereference AttachNewFile()
    {
        try
        {
        delete [select id from Attachment where ParentId=:CurrentId];
        Blob b = Attach;
        Attachment At = new Attachment(Name ='NewFile'+'.jpg',body = b,parentId=CurrentId);
        insert At;       
        }Catch(Exception ee){}
        return null;
    }
}

toolbar background color in visualforce apex Salesforce

2011-09-08T10:06:00.000-07:00

Dear guys..

I had a big issue while working with <apex:toolbar>. The default appearance is green-to-black gradient.
If we are setting in

<apex:toolbar style="background-color:blue"> or any hexadecimal Number it does not works.
In this style sheet we have to include something else too.
<apex:toolbar style="background-color:gray;background-image:none">

The whole example is given below.

<apex:page id="thePage" standardstylesheets="true" showheader="false">

    <apex:toolbar id="theToolbar" height="50px;" itemSeparator="disc" style="background-color:gray;background-image:none">

        <apex:outputText value="Sample Toolbar"/>

        <apex:toolbarGroup itemSeparator="disc" id="toobarGroupLinks">

            <apex:outputLink value="http://www.salesforce.com"><span style="color:Blue">salesforce</span></apex:outputLink>

            <apex:outputLink value="http://developer.salesforce.com"><span style="color:Blue">apex developer network</span></apex:outputLink>

        </apex:toolbarGroup>

        <apex:toolbarGroup itemSeparator="disc" location="right" id="toobarGroupForm">

            <apex:form id="theForm">

                <apex:inputText id="theInputText">Enter Text</apex:inputText>

                <apex:commandLink id="theCommandLink"><span style="color:Blue">Search</span></apex:commandLink>

            </apex:form>

        </apex:toolbarGroup>

    </apex:toolbar>   

</apex:page>

Changing Date Format On Visualforce Page in Salesforce Apex

2011-09-05T05:27:00.000-07:00

Dear Guys....

We have a some idea regarding date format on visualforce page.Usually when we display the date field value on visualforce page it make the date format.
In case we dont want to see this format we need to show only the format which should be easy to understand to all like some different formats.
MM-DD-YYYY or YYYY-MM-DD Like these format.

We have to ways to achieve the date.
1. We can create a method by passing parameter type Date or Date Time whatever you passing depend on you.
And then call this method before showing the date field value of visualforce page.

Opportunity opp =  [select CloseDate from Opportunity Limit 1];
string DateString1 = ConvertDateFormat(opp.CloseDate);
public string ConvertDateFormat(Date d){ 
string DateString ;
string month;
  if(d!=null){
     integer d1 = d.day();
     integer d2 = d.month();
     if(d2 == 1)
      {
        month = 'january';     
    }
    if(
        d2 == 2){month = 'February'; 
     }
    if(
        d2 == 3){month = 'March';   //so on.............................
     }
    integer d3 = d.year();
    DateString = string.valueOf(d1)+'-'+month+'-'+string.valueOf(d3);
}return DateString;

}

system.debug('***********'+DateString1);

So guys in this why we can format our date as we need.
2. Apart from this code we have another way to directly format the date on visualforce page.
We have a Apex Tag <apex:parma> which pass the value to the output text..
Lets say we have a date Field we can directly pass it to the visualforce tag.

<apex:outputText value="{0,date,dd-MMMM-yyyy}">
                  <apex:param value="{! Opp.CloseDate}" />
</apex:outputText>

Highlighted text decided the in what way your date format would be display on visualforce page. You can this format by replacing the value in the format.
{0,date,dd-MMMM-yyyy}
{0,date,MMMM-dd-yyyy}
{0,date,MMMM-yyyy-dd}

{0,date,dd-MM-yy}
{0,date,MM-dd-yyyy}
{0,date,MM-yy-dd}

You can check more probabilities by your self will make better understanding for you.

Please promote it this post help you and also let me know if I am doing something wrong in the post.

Thanks

Custom Settings in salesforce apex

2011-09-02T01:52:00.000-07:00

Hello folks..
We have some interesting here......

Some times we need to configure some custom objects which are apart from any relationship. Suppose we need to configure a object Name System Configuration where we are putting some values . Dynamic values mean we can change these values based on our requirement.

Now while development we are setting the criteria based on these values.

Lets say we a object Name System_Configuration in which we have two date type field.
Start_Date
End_Date

Now we are querying the Any List of object suppose

List<Opportunity> lstOpprtunity = [select id,Name,Stage from Opportunity where CloseDate Start_Date And CloseDate <=End_Date];

So the thing is first you will have to query on the System_Configuration Object to pick the Field values Start_Date And End_Date and only then you can use these values in your filter criteria.

Now if we want escaping these kind of unnecessary queries we have the SALESFORCE CUSTOM SETTINGS .

These custom setting are just like salesforce custom object but these object have limited number of data type.
And having different type of methods which provide you convenience way to extract the data of these custom setting objects.

Why I am referring custom setting while we can do this by using salesforce custom objects. The reason is give below with the more descriptive definition of Custom setting.

Custom settings are similar to custom objects and enable application developers to create custom sets of data, as well as create and associate custom data for an organization, profile, or specific user. All custom settings data is exposed in the application cache, which enables efficient access without the cost of repeated queries to the database. This data can then be used by formula fields, validation rules, Apex, and the Web services API.

The best example of custom setting is given below link :

Go a head the try it your self.

Query String Parameters in Apex Salesforce And Param Visualforce Component.

2011-08-29T01:55:00.000-07:00

Hello guys.....
Its much interesting topic for the beginner of salesforce developer.

Have a look on Qurey String Parameter :
Create a visualforcve page with Account as Standard Controller to show the All contact link and their phone no detail for a single account Id.

I am creating a simple visualforce standard controller of Account Object.

<apex:page standardController="Account">
    <apex:pageBlock title="Contacts">
        <apex:form>
         <apex:dataTable value="{!account.Contacts}" var="contact" cellPadding="4" border="1">
         <apex:column><apex:facet name="header">Name</apex:facet>
            <apex:commandLink>
                     {!contact.Name}<apex:param name="cid" value="{!contact.id}"/>
            </apex:commandLink>
         </apex:column>
           <apex:column>
              <apex:facet name="header">Phone</apex:facet>
                  {!contact.Phone}
               </apex:column>
         </apex:dataTable>
        </apex:form>
    </apex:pageBlock>
    <apex:detail subject="{!$CurrentPage.parameters.cid}" relatedList="false" title="false"/>
</apex:page>

After creating the visualforce page ur URL would be somthing like this..
https://ap1.visual.force.com/apex/QueryStringParameters
put any of salesforce Account SFDC id which contains number of contact in query string like this .. ?id=00190000005g1db
Now url would be

https://.visual.force.com/apex/QueryStringParameters?id=00190000005g1db

this is ur account Id starting from 001

Now will can see the details Contact Name in First Column and Phone in second column.
Now Name column is a link when u click on this link ...u can see the detail of that particular contact. Now the thing is how is this happening.

When u click on that link u r passing a query stinng parameter through Apex Param tag.
<apex:param name="cid" value="{!contact.id}"/>

Its send the contact Id to the cid parameter which pass in to the

 <apex:detail subject={!$CurrentPage.parameters.cid}" relatedList="false" title="false"/>

Visualforce Tag. U can see {!$CurrentPage.parameters.cid} is the standard format to get the query string as parameter.

Apex heap size too large And Too Many Script Statement in apex salesforce

2011-08-27T08:01:00.000-07:00

Hi guys these kind of error I had faced many time because of the large data in organisations. When ever we process the number of records governor limit hit these kind of error.

Normally we queried the records like.

List<Account> lstAcc = [select Id,Name from Account];
for(Account Acc :lstAcc){
    //your code here     Running statement for each records. And Hitting the script statement limit

}

We can use this in another way by which we can escape two kind of error mentioned above.
We can do a SOQL inside the for loop something like this.

for(List<Account> lst :[select Id,Name from Account]){
     // Loop first statement having 200 records in single batch.
}

This way is only for when you are not tracing one by one object and making calculation. We can use this ways if we are adding all records in a new list .

for(List<Account> lst :[select Id,Name from Account]){
   newList.addall(lst);
}

Suppose we have 500 records to process the this loop will run max 3 time.

This line of code reducing the script statement because this structure make the batch of 200 record for a single statement. And This is also reducing the Apex Heap size.

Cheers..........................

Best Practice of escaping the govenner limits in apex salesforce

2011-08-27T07:46:00.000-07:00

Hi guys I have a interesting topic to escaping the governor limits hitting in our apex script.
I just have the trigger on object Account which exposing some limits hitting in apex. And we can escape it by inspecting the limits while executing the script.

trigger LimitExample on Account (after delete, after insert, after update) {

      

    System.debug('Total Number of SOQL Queries allowed in this apex code context: ' +  Limits.getLimitQueries());

    System.debug('Total Number of records that can be queried  in this apex code context: ' +  Limits.getLimitDmlRows());

    System.debug('Total Number of DML statements allowed in this apex code context: ' +  Limits.getLimitDmlStatements() );

    System.debug('Total Number of script statements allowed in this apex code context: ' +  Limits.getLimitScriptStatements());   

  

   //This code inefficiently queries the Opportunity object in two seperate queries

    List<Opportunity> opptys = [select id, description, name, accountid,  closedate, stagename from Opportunity where accountId IN :Trigger.newMap.keySet()]; 

    System.debug('1.Number of Queries used in this apex code so far: ' + Limits.getQueries());

    System.debug('2.Number of rows queried in this apex code so far: ' + Limits.getDmlRows());

    System.debug('3. Number of script statements used so far : ' +  Limits.getDmlStatements());     

  

   //NOTE:Proactively determine if there are too many Opportunities to update and avoid governor limits

   if (opptys.size() + Limits.getDMLRows() > Limits.getLimitDMLRows()) {



            System.debug('Need to stop processing to avoid hitting a governor limit. Too many related Opportunities to update in this trigger');

            System.debug('Trying to update ' + opptys.size() + ' opportunities but governor limits will only allow ' + Limits.getLimitDMLRows());

            for (Account a: Trigger.new)

                a.addError('You are attempting to update the addresses of too many accounts at once. Please try again with fewer accounts.');

    } 

    else{

        System.debug('Continue processing. Not going to hit DML governor limits');

        System.debug('Going to update ' + opptys.size() + ' opportunities and governor limits will allow ' + Limits.getLimitDMLRows());

        for(Account a : Trigger.new){

            System.debug('Number of script statements used so far : ' +  Limits.getDmlStatements());                       

            for(Opportunity o: opptys){

                if(o.accountid == a.id)

                   o.description = 'testing';

           }         

        }

        update opptys;

        System.debug('Total heap size: ' +  Limits.getLimitHeapSize());

        System.debug('Final number of script statements used so far : ' +  Limits.getDmlStatements());
