I don't really understand what you want. if you are looking to call a C++ method from your C# code and you have the C++ DLL and .h files, we need to know what the method is you want to call, it's return type, and any parameters it takes. normally the .h file will have this information.

Was there a problem with the reply I made in your original thread? It's rather complicated, and requires that the C# DLL be properly built to support being called from C++.

Well in the other thread someone did ask that he post here to get help.

Basically if you are using mannaged C++.Net then it is no problem to call C# dll from C++.

HOWEVER if you are working with non-mannaged C++ then it does become a little complicated since the C# dll will need to run on the .Net framework.

Why are you mixing languages? Why not just use 1 or the other. Chances are you can do what you need in C# rather than using C++ unless you need to do something outside of the .net framework in which case this will get complicated.

Please don't create duplicate topics, it doesnt help you to get help any faster, and can actually slow it down since people don't know which thread to reply to smile.gif I'm merging the two topics smile.gif

NickDMax is pretty much spot on.

The only other way I can think of doing this is by using COM. Your C# dll Will have to use COM and Interop.

Let me google and see what I find: ... ah here we go

If you don't know COM or how it works this may not be the best solution for you.
