Hello.

I have two classes:
ClassA (Include 2 method: M1, M2)
ClassB (Include Implement of ClassA + New Method M3)

In my program I define the class (as written in MSDN) like this:

Dim ObjA as ClassA
Dim ObjB as new ClassB

set ObjA = ObjB




The problem is that ObjA don't recognize the method M3 !!!
What can I do ???

Thanks for any help.
