Question: Catching errors from a VB ActiveX control in Visual C++ using MFC
I am not sure what you mean by using Try and Catch in VB, it does not use
those as keywords. So far as catching you can implement it kind of. Using
your example
Function SomeFunction() as Boolean
On Error Goto Catch
SomeFunction = True
....Some Code
Err.Description = "Device not Found on " & m_Port
Err.Raise vbObjectError + 7
SomeFunction = False
Exit Function
Catch:
...Error Handling Routine For above Function Here
End Function
Hope this helps you......
