Problem with recompiling OCX - CLSID

[yapp]

Hello there.

I have created some controls (like coolbar, subclassing, hooking controls).

However, If I recompile the source, the classes in the control get a new CLSID. Old programs can't use my control anymore.

How can I recompile without needing to recompile the other programs aswell. I have heard something about working with typeLibs. Can anyone explain that topic aswell?

hi there yapp,
I think what u want to do can be achieved by setting the OCX/DLL projects Version Compability mode to Binary Compability

MSDN

Binary Compatibility — Useful for maintaining compatibility among projects that have been compiled using your component.

I have been using that. Thanks for your fast reply anyway

Binary compat. is not exactly what I want.
I have seen some magic with type libaries...

Binary compatibility recompiles the project, but creates a new version of the VTABLE for each class. The VTABLE is a table with data about all the methods attached to a class.

I want to create a fresh new file, with is still compatible with the previous file. Off course I can't change the method names or parameters, but it would be nice If I can even overrule that...
