Visual C++ file selection dialog

In Visual C++ 6.0, I require to select a file to open and would like to use the standard file selector dialog to get a filename. What function do I call for that? Does anybody know of a web page with some sample code, or just the function name that I could look up?

GetOpenFileName, look it up in the MSDN.

or CFileDialog which is an MFC wrapper around GetOpenFileName.

and ditch Visual C++ 6.0, it's a buggy broken compiler. Get the free visual studio 2005 express instead (or dev-cpp)

CFileDialog won't work in the free Visual Studio 2005 Express though

The CFileDialog requires that I add an #include<afxdlgs.h>, but the latter does not permit me to include windows.h which I need with CreateThread and CreateSemaphore. What do I do?
