Show Dialog

I have the following code:

Code:

---

#include "stdafx.h"

int APIENTRY WinMain(HINSTANCE hInstance,
                    HINSTANCE hPrevInstance,
                    LPSTR    lpCmdLine,
                    int      nCmdShow)
{
       
        return 0;
}

---

Is it possible to show a Dialog based on this, or do I first have to write a Window Class for the "base window"???

You can make a modal dialogue box using DialogBox, where the function doesn't return until it's closed (you still need to provide a dialogue box procedure, similar to a window procedure).
A modeless box is created using CreateDialog, and this returns a window handle as normal. For this you have to use a message loop as well.
