Viv,
Like I said. Even if it compiles it doesn't mean it is good code :)

>I can see that, in this case, the 'return' will never execute (incidently VB.NET doesn't flag this up). But I was under the impression that a 'return' would never work in a try block (help states "You cannot branch out of a TRY block, into a CATCH block, or into or out of a FINALLY block"). However it looks like I was wrong:

>    MsgBox("Back to Outer")
>  Finally
>    MsgBox("Outer Finally")
>EndTry
>MsgBox("Normal Return")
>End Sub

>This VB code runs both Finally blocks then executes the Return (ie "Back to Outer" and "Normal Return" don't execute). Oh well, live and learn....
