Sorry in advance! I did solved thread before I checked if the code somebody said worked. It turned out they didn't help much. The problem is MattyRobot gave me code to open a new window. Now it opens with CMD to; I only wanted the window. I will give you the code, and would appreciate if you edited so the cmd window does not open with the window. So basicly I want a code where just the window opens. If you could sort out the one i was given, would be appreciated. Just sort it out and post it back on this forum.
Thanks!

    ShowWindow(hwnd, SW_SHOW);
    UpdateWindow(hwnd);


    while(GetMessage(&msg, NULL, 0, 0) > 0)

        DispatchMessage(&msg);

}

Sorry, forgot to add; please dont comment if you dont understand. Nevertheless if you can help, feel free to :)

I'm afraid the code is correct :)
The problem is a compiler setting, make sure the project is a "Windows Application".

And if you seriously can't figure out the compiler option (and you're using VC++), add this line of code to the very start of your program.
