When I close my application, it always gives me this error at line...

MyBase.Dispose(disposing)

The error...

An unhandled exception of type 'System.NullReferenceException' occurred in
system.windows.forms.dll

Additional information: Object reference not set to an instance of an
object.


Here is what I am doing in the form...
I have a Datagrid on a form. I have a DataSet that I am constantly updating
the rows with data I am pulling from some webservices.

Thank you for your help.
 
Oh, I have a Timer (System.Timers.Timer) that runs every 10 seconds that
calls the sub that updates the DataSet.
 
Make sure you stop the timer before you Close or Dispose the form.
I'd do this in the Form_Closing Event - just Timer.Stop or Timer.Enabled =
False.
If that doesn't help, trace the error back through the call stack using the
debugging features of the IDE.
