OT: Defined before windows

[JKop]

I hear that to write a proper C++ program for Windows, you
should declare certain macros before including "windows.h".

Could some-one please tell me what these are and/or point
me to a nice site that would explain them.


Thanks,

Check MS newsgroups. However my recommendation on the subject is .NET.

This would be better suited to a Windows group.

It's not really necessary, afaik. What you mean however is most likely the
version macros. It is recommended to define the _WIN32_WINNT macro or the
_WIN32_WINDOWS macro ìn addition to the WINVER macro to hold the value of
the Windows version you're targetting, like this:
#define _WIN32_WINNT 0x0501
#define WINVER 0x0501

See:

There's also the WIN32_LEAN_AND_MEAN macro that most people define before
#include <windows.h> because it instructs it to leave out certain rarely
used parts which greatly improves compile time.
