Description

Enables or disables error handling within a procedure.

If you don’t use an On Error statement or a Try...Catch block in your procedure, or if you have explicitly switched off error handling, the Visual Basic runtime engine will automatically handle the error. First, it will display a dialog box containing the standard text of the error message. Second, it will terminate the application. So any error that occurs in the procedure will produce a fatal runtime error.
