I have a VB6 EXE project with a large amount of classes – everything compiles to an EXE, there are not COM DLLs built.
Some of the classes implement the IDataProcessing interface. How can I programmatically determine the classes that implement that interface?
You could use TypeOf SomeClass Is IDataProcessing if you have access to both classes or interfaces.
Or are you just wanting to iterate through all classes and check which implement that interface? There is no way to do that with classes in an EXE that I’m aware of.
