how i can get any exception error using try and catch
From the OLR:
The following catches any exception in the code block:
Try Dim d As Date d.TotalSeconds = 1000 Catch e As RunTimeException If e IsA EndException Or e IsA ThreadEndException Then Raise e // Re-raise the exception for the framework End If MsgBox(e.Message) End Try
Of course, you could adjust the Catch section for far more exceptions. The special sauce here is to raise the exception so that the framework can do what it needs to do after you’ve handled the ones that you are interested in trapping.
In that example, only “EndException” and “ThreadEndException” would be raised while any other would simply be reported and ignored.
