SYMPTOMS

The Shell statement can cause a Invalid Procedure Call even though the Shell statement successfully started the desired application.

WORKAROUND

To work around this bug, turn error trapping on and trap the Invalid Procedure Call error as in this example:

   On Error Resume Next 
   Shell("C:\WINDOWS\NOTEPAD.EXE")
 ' Invalid Procedure Call:
  
   If Err <> 5  Then
 
      ' Insert code to handle other errors here.
      ' Exit if fatal

   End if
