Trying to use an SPWeb object that has been closed or disposed and is no longer valid.

Hi Guys,

You may have faced this kind of error while coding the webparts and provisioning them in SharePoint pages. May be you will face this issue while trying to edit a page, that having the webpart with below code

using(SPWeb web = SPContext.Current.Web)
{
//Your code here
}

Issue is with using statement, its disposing your SPWeb object automatically when you leaving using block. Use below than the above block

SPWeb web = SPContext.Current.Web

Hope you will figure it out within your code.

Happy coding guys,

Debugging a Timer job

Hi Friends,

May be you are running with the time for creating Sharepoint timer job creation. You have started to create a feature with Event receivers, feature receivers and basic timer job class structure like below.

public class TimerJobClass : SPJobDefinition
{
      //Your contructors to handle different combinations of parameters
      public TimerJobClass()
     {
     }
    
     public TimerJobClass(string jobName, SPService service, SPServer server, SPJobLockType targetType)
            : base(jobName, service, server, targetType)
     {
     }

     public TimerJobClass(string jobName, SPWebApplication webApplication, string targeturl)
            : base(jobName, webApplication, null, SPJobLockType.Job)
        {
            this.Title = "Timer Job Name";
        }
    
      public override void Execute(Guid contentDbId)
      {
            //Things need to do.
      }
}

After this structure declaring, you may be started with sample method designing and try to debug the timer job with below line

System.Diagnostics.Debugger.Break();

You may be wonder that you have copied the dll to GAC and did a IISRESET, and ran the sp timer job definition but the debugging engine of the VS 2010 never fires even after run the timer job.

I know your problem, Restart the "Sharepoint 2010 Timer" job  and then start the IISRESET. ....magic appears.....there you get the debugger fires upon the timer running.

Happy coding,
