The Workflow status are constants (integers), So you'll need to refer to a list like:

1. Status: Value

3. Failed On Start: 1

4. In Progress: 2

5. Error Occurred: 3

6. Canceled: 4

7. Completed: 5

8. Failed On Start(Retrying): 6

9. Error Occurred (Retrying): 7

10. Canceled: 15

11. Approved: 16

12. Rejected: 17

ECMA SCRIPT SHAREPOINT 2010

SharePoint provides two sets of JavaScript file: minified and unminified/debug version.
For example sp.js file is minified and sp.debug is minified and debug version. The default master page in SharePoint has a scriptmanager in the page and whose ScriptMode is set to auto, as a result the minified version of js file loaded.
If you want to use debug version you can add the <deployment retail="false" /> in the <system.web> section of the web.config. In the production you need to remove this entry to make sure minified version is used.

Managed Client
DLL's needed : Microsoft.SharePoint.Client.dll, Microsoft.SharePoint.Client.Runtime.dll. Find these files in the 14/ISAPI folder. Usually, the location would be at "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI".

Silverlight
Microsoft.SharePoint.Client.Silverlight.dll and Microsoft.SharePoint.Client.Silverlight.Runtime.dll. They find at "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\ClientBin".

ECMAScript
SP.js file - The file fund at "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS".

Debugging Feature Receivers

Feature receivers can be difficult because they are often executed within a separate process. To see an example of this problem put a breakpoint on the first line of our FeatureActivated method and try debugging using Visual Studio.  The code will be deployed and the feature will be activated, but execution will not stop at the breakpoint.  Visual Studio makes use of a separate process, VSSPHost.exe, to automate the deployment only, and therefore the breakpoint is never hit but the code still execures.

        We can work around this issue in one of two ways: we can either attach a debugger to the appropriate process, or we can ensure that our feature receiver runs in the W3SVC process. To ensure  that a debugger is attached to the correct process, we can take the following steps:

   

            1.   Add the following line of code to the method to be debugged:

    Debugger.Break();

   When error window open then select “Debug the Program”
