Q. How do I use the _MSC_VER predefined macro?
A. The help file says:
Reports the major and minor versions of the compiler.
For example, 1310 for Microsoft Visual C++ .NET 2003. 1310 represents
version 13 and a 1.0 point release.
There is code around that seems to think its hex - eg 0x1310. This WRONG!
(WINVER is like that.)
The simplest way to use it is to test if you are using a Microsoft compiler or not:
#ifdef _MSC_VER
// Using some version of Microsoft Visual C++
#else
// NOT using some version of Microsoft Visual C++
#endif
If you need to check the version, do this:
#if (_MSC_VER >= 1400)
// This is Visual C++ 8.0 (Visual Studio 2005)
#elif (_MSC_VER >= 1310)
// This is Visual C++ 7.1 (Visual Studio .NET 2003)
#elif (_MSC_VER >= 1300)
// This is Visual C++ 7.0 (Visual Studio .NET 2002)
#else
// This is Visual C++ 6.0
#endif
