I need code for a basic window.

I'm starting to build up my reference library and I was wondering if anybody could show me the code for making an empty window in C++ to put the program in.

Put the program in? Up until there it seemed like you just wanted some kind of normal window, but now I'm not so sure.

If you do just want a normal window, it'll be OS dependent or at least require an external library.

Here is the window skeleton I found. It compiled fine with MS Visual C++ 2012 Express. Hope it helps you out.

Thanks, this looks like it should.
