Hi, Since I couldn't find any solution to the problem, nor are there any replies here in this forum :(, I finally decided to go in for a C# based P/Invoke method of calling the native DLL. I know it sucks compared to the MC++ wrapper solution, but hey, at least it works! For those who are stuck in a similar situation, they can try using the [PInvoke Interop Assistant]. This is a wonderful open source tool that makes it really simple to create an automated wrapper for native dlls. There are a few articles in MSDN magazine on how to use this tool too. It comes with a command-line interface that allows easy porting of entire header files in the easiest manner possible. Just supply your header files to this tool, and it'll write out almost the entire wrapper declarations. Just to make sure though, you should manually examine all the ported declarations, ensuring that no mistakes are present.
