Resuming from an error

In VB6 one could use 'Resume Next' to have program execution resume at the
statement following where an error occurred. Is there something comparable
in VB .NET?

Try

i = 0 / 0

DoEvenMore

Catch ex As Exception



End Try

If the eval of i creates an error how do I have the Catch block resume
execution at the procedure DoEvenMore?

You know, you can do an On Error GoTo and Resume Next, which you'll have to
get rid if the try/catch.

Try

i = 0 / 0

Catch
'no code here. ignore exception.
End Try

DoEvenMore


Don't be surprised if you don't get an exception in this case at all...

How about

Try
i = 0 / 0
Catch ex As DivideByZeroException
' i = 0 ?
Finally
DoEvenMore()
End Try

ACK, but you'd have to put each statement in a separate 'Try...Catch' block
in order to receive a behavior similar to those of 'Resume Next'.

Yes.

"On Error Resume Next"

Yes, it /still/ works; if you really, /really/ want to.

More likely, though, you'll want to use Try .. Catch ... won't you!?

Sub X()
Try
DoSomethingDodgy()
Catch ex As Exception
' Do Nothing
End Try

DoEvenMore()

End Sub

Unless you [re-]throw the Exception out of the Catch, execution
continues with the next statement /after/ the End Try.
