Alright so I have this C++ image capturing class. I was wondering if I could get some help..I know basic C++ (I have done one intro to c and one intro to c++ class) and I have NO idea how to do this:

I need to use this class (ie create a new c++ project in my solution) and use c# to reference it and use it to save a screenshot of the screen.

When I try to add a new project I dont know which one to choose (win32, mfc, atl, clr, abc, xyz, and so on) .

The image capturing class is here: http://pastebin.com/m72414ab

I don’t know if I need to create .h files or just a .cpp file would do.. like honestly I have no clue where to start lol. I am looking for a solution, but i want to learn in the process so I dont have to ask next time (not to mention that I like c++ so I am gonna continue coding with it)

  1. You cannot easily use C++ classes from C# without knowing some somewhat specialized information about C++/CLI – either rewrite your C++ class in C and use P/Invoke, or find a fully C# solution.

    But I’d like to use this c++ class for speed and memory.

    I question this, unless you are capturing images thousands of times a second, there’s no way choosing C++ would be of any benefit, and it makes your program much more complicated. Stick with C# until you know you need the slight performance boost.
