//Assume you have managed to somehow pass a function pointer from C++ as Cplussplusfunctionptr to C#. In my case I was lucky, becoz I had managed C++ as a mid layer to convert void* to IntPtr;

IntPtr func = Cplussplusfunctionptr;
 
GuiFactoryOnNotify delegateOnNotify = (GuiFactoryOnNotify)Marshal.GetDelegateForFunctionPointer
                (func, typeof(GuiFactoryOnNotify)); 
 
 
Thanks to cory nelson in stack overflow for the original tip.

Thanks for the reply.
Lemme explain a bit further:
I have a running application (written in C) exposing some normal and call back functions. What I have managed was able to refer the LIB/TLB to my C# application and call the functions, using DllImport and this is done using the application executable from the same folder of my C# application.
 
As the application is already running under Windows, I think I need some IPC kind of thing in order to directly communicate to the Running Instance of the application.
