Create Windows Program with GUI but use 'main()' (in D)?

Question

Is it possible, to in Windows, create a GUI program, which has it's entry point in 'main()'? How do I do this?

My use for this is that I want a cross-platform application, with one uniform entry point.

Answer 1

1. Write your application using main() and all the GUI calls in there that you would have used in WinMain. This will create an application with both a GUI and a console window.
2. Use the Windows SDK tool editbin /SUBSYSTEM:WINDOWS appname.exe to change the subsystem flag in the PE header, so Windows won't create a console window automatically.
3. If you want to have a working stdout for debug message or the like, you can either use freopen to direct stdout to a file, or AllocConsole when you decide a console window is needed (for example, after an error occurs).

BTW: This thread indicates that the DMD compiler will prefer main() over WinMain() anyway if it finds both.
