Triggering events when a job from SQL server finishes

I am writing an application that shows a list of jobs available from SQL server. It allows the user to select a job and start it. My question is how do I let the user know that the job has finished before executing the next job. I know that in VB 6 you had some events that were triggered by a connection object(Execute_Complete) but that is not the case in vb.net. Is there a way that this can be done?

Thanks

Well if you are just looking for an equivalent of Execute_Complete you can use StateChange event of the Connection object.

For eg
Say you have a connection...
Dim Cn as SQLConnection=New SqlConnection(ConnectString)

Create a Handler for StateChange Event...
AddHandler Cn.StateChange, New StateChangeEventHandler(AddressOf OnStateChange)

Then..
Public Sub OnStateChange(sender As Object, args As StateChangeEventArgs)
       Here Check if args.CurrentState is not one of Connecting,Executing and Fetching, it means it is idle
       Also to be sure you can check if args.OriginalState was either Executing or Fetching based on your query

End Sub
