Is it possible to redirect standard output to the output window from Visual Studio?
I use OutputDebugString in my program, but I use some libraries that
Yes. I'm assuming that you're working on a Win32 GUI application.
Your C implementation defines three handles for standard input, standard output, and standard error. Win32 defines equivalent handles, which define where the actual physical input/output will appear. C functions, such as 'printf', use these Win32 handles to perform I/O. Basically, you have to create a console for output, and then redirect where the Win32 standard output points to. And then getting the handle to the C standard output and associating this with the Win32 standard output.

You'll need to add two new files to your application (the link contains the listings).
