ActiveX

I using ActiveX DLL B in application A. After make EXE file A, i change DLL B and recompile it. Every one time recompile B i must remake application A
Help me !

in the IDE go to the Project Properties dialog an from the "Component" tab select binary compatibility.
(and read the online docs about compatibility)

Thanks for your help me !!!

When an Application is using your component(DLL),You Should Change the Name of the Existing Method/Property/Class. If you change, existing application may not work properly.

And it is not that every time when you Modify&Compile your component you should re-compile your application(Which is impossible in real-time scenario).

All that you will have to do is Set the Version Compatibility Option Available in the Project-Component of the Component(DLL) to Binary Compatibility.

Now if you re-compile your COMPONENT you need not re-compile existing application. Reason When You select Binary Compatibility option CLASSID & GUID are Preserved. It does't generate a new ones.
