Hello
I am getting this error
_WIN32_WINNT not defined. Defaulting to _WIN32_WINNT_MAXVER (see WinSDKVer.h)
I was already defined this _WIN32_WINNT in Preprocessor definitions as
_WIN32_WINNT=0x0502
why i am still getting this error?
please reply me.

On reflection, and based on your comment below, I suspect you have added this to your Project properties. However, it is likely that you added it to the properties of the Debug build but not the Release one.

good catch, but he shouldn't define there anyway, so your solution is better :)

I'm just trying to cover all the bases. :)

Solution 2

The correct format for the define is

#define _WIN32_WINNT 0x0502

and this statement must come before any #includes in the StdAfx.h, or whatever include you use to build the precompiled headers.

My code is working in debug mode but in release mode it shows like that why

Albert Holguin 25-Apr-11 10:20am

debug must be ignoring your invalid macro statement all together

We cannot guess what is happening, please post the code you are using (edit your original question above, and add the detail there).
