I'm not exactly sure what you can (or should) do with *.rc files. Most Win32 example code, including Visual Studio templates, creates the main window programmatically in WinMain. I could create a dialog in the resource script and just show it in WinMain, but I'm not sure if that's the best idea, since dialogs are treated differently than windows. Is there a way to put controls in the main window from a resource script, or should I just create it as a dialog?
