• Scott1978 What's the point of Finally?

  I was wondering, what is the point of having a "Finally" section in a Try-Catch-Finally block I was taught that a Finally block is for where you want the code to end up regardless of if an exception was caught or not. But if that's all we want to do, why not just let it continue after it falls out of the entire Try block For example, what's the difference between these two sections of code Sub FileCopyWithFinally()    Try    ...Show All

  Do you need to use AcceptChanges after a TableAdapter.Update I know it's an option for DataAdapters, but I'm guessing it's automatically called during a TableAdapter.Update.

• Scott Cairney Toolbar buttons fail to recieve buttonclick event.

  I just discovered a nasty quirk that can mysteriously kill toolbar buttons. If you raise a MessageBox while processing the Load event while launching a form, the toolbar buttons on the form no longer receive the buttonclick event after it appears on screen. They depress and display tooltips, but don't produce any action. I am using Visual Basic .NET in Visual Studio 2003.   This actually makes sense, si ...Show All
