Graceful Exit

Having one entry and one exit point to a sub or function is very good
programming practice. Where errorhandlers are concerned this practice
sometimes gets bent a little and I'd like to share a very, very simple solution
to ensure a nice flow and exit from a routine.....no exit sub or exit function
statements to be seen.
Function Test()

' Dim your local vars etc

On Error Goto ErrorHandler:

' Do the stuff in the function.

ErrorHandler:

' Check to see if an error has been raised.
If Err <> 0 Then

' Do the Error Handler stuff here.

End If

' Turn off the Error Handler.
On Error Goto 0

' Gracefully drop out of the routine.

End Function
