Question

I’m working on a directx application and was wondering how I could add a regular window to the application, one which has text boxes, command buttons and all.

Answer 1

For a window to exist it will require a windows forms message pump :

A Win32 message pump typically looks something this and was the heart of win32 programming.

MSG msg;
while(GetMessage(&msg, hwnd, 0, 0))
{
    TranslateMessage(&msg);
    DispatchMessage(&msg);
    // do stuff
}

Today, the C# language tends to abstract the message pump away but you can still get to it.

    protected override void WndProc(ref Message m)
    {
        base.WndProc(ref m);

  // do stuff

    }

You need a call to application.run to launch a windows forms with active message pump. see :
