For Example:

<apex:column title=”{!$ObjectType.OpportunityLineItem.fields.Quantity.label}” headerValue=”{!$ObjectType.OpportunityLineItem.fields.Quantity.label}” width=”50px”>

It also avoids hard-coded labels and make it more flexible.

<script type=”text/javascript” src=”http://www.google.com/jsapi”></script>

with

<script type=”text/javascript” src=”https://www.google.com/jsapi”></script>

Its really frustrating. Dont know this is the solution for this or not. But it worked for me!!

{faultcode:'sf:INVALID_SESSION_ID', faultstring:'INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session', detail:{UnexpectedErrorFault:{exceptionCode:'INVALID_SESSION_ID', exceptionMessage:'Invalid Session ID found in SessionHeader: Illegal Session', }, }, }

The exception was resolved when I added following statement before using the “sforce.connection” object in the JavaScript.

sforce.connection.sessionId = “{!$Api.Session_ID}”

myDateTime.ToString(“u”)

OR

string strDate = DateTime.UtcNow.ToString(“yyyy’-'MM’-'dd’T'HH’:'mm’:'ss’Z'”, DateTimeFormatInfo.InvariantInfo);

The custom format string is “yyyy’-'MM’-'dd HH’:'mm’:'ss’Z'”.

(?!^[0-9]*$)(?!^[a-zA-Z]*$)^([a-zA-Z0-9]{8,20})$

The above RegEx requires at least one digit, at least one alphabetic character, no special characters, and from 8-20 characters in length.

Awsome explanation of Salesforce working!

I solved this by right clicking on the project in eclipse then on going to the properties.  And configuring the Framework linkage to merge in code value. I dont know this was the correct way to do that or not.

System.debug(DateTime.now().format(‘yyyy-MM-dd\’T\’hh:mm:ss\’z\”));

I hope this will save your time.

This makes it easy to backup more of your key files online, from large graphics and raw photos to unedited home videos taken on your smartphone. You might even be able to replace the USB drive you reserved for those files that are too big to send over email.
