How to integrate VB.NET with C++
-
Hi I am in the process of adding video capture functionallity with the use of the DirectShow API. My program has been written in VB.NET, but due to compatibility issues I have been writing code in C++ so that I can fully access the directshow api. But I seem to have hit bit of a brickwall in attempting to integrate the code. I thought it was possible to be able add the c++ project into the VB.NET project, and be able to make function calls from the VB.NET GUI interface with the C++ code. Is this possible? Another option that I am now considering is exporting the c++ code as a DLL file and from there I can access the c++ as a library file? Although I would prefer my first suggestion if this is possible? Any suggestions would be greatly appreciated Cheers boyindie

Yes, you use pinvoke for that, and yes, your C++ code needs to be in a dll. Or, you can make your code C++/CLI, then you can call it directly, but it still needs to be a dll
