Where is Winnt.h file in VS2005

Question

I am reading Charles Petzold's Programming windows. 5th Edition. And there is a statement to Windows.h file.

It said.

There is a WINNT.H file included in Windows.h file.

And the WINNT.H file used to define Unicode support.

But I can't find it in Visual Studio 8.0 Windows.h file.

And the file (WINNT.H) is not existing in Windows.h in VS 8.0, How can the Unicode support function be realized?

Answer 1

If you have the Visual C++ component of Visual Studio installed (i.e. if you can compile .cpp files), then you have WINNT.H. As well as Windows.h (which implicitly #include's WINNT.H for all Win32 targets).

It should be under "\includes" in your MSVS install directory.

In earlier versions of MSVS, 8-bit ASCII was the default, and you had to explictly "#define _UNICODE" (e.g. as a compile option). Newer versions (I believe starting in MSVS2005, but certainly now in MSVS2008 and MSVS2010), 16-bit Unicode is the default.
