undeclared identifier

All,

I could use some direction here. I am learning C++, although I have
programmed in C for some time.

I am also working with ATL objects and have been doing quite well.

My problem is that I am getting "Undeclared Identifiers" on function names
and structures for NetWkstaUserGetInfo, NetApiBufferFree, and others
although I have <windows.h> and <lm.h> included. I looked at <lm.h> and it
includes <lmwksta.h> which has the actual definitions in it.

I have used the API call GetUserName with success.

My question is what in the blazes am I doing wrong?

TIA,

Justin

Chances are that the compiler doesn't realize that you target Windows
NT/2000/XP/2K+3

Try adding this line

#define _WIN32_WINNT 0x0400

ahead of the place in your source where you included <windows.h> or a header
that includes it.

Will

William,

Thanks for the response. I tried your suggestion. Still received the same
errors.

I created a blank console program and tried the code and it compiled with
success. I created a new ATL project and tried the same code and it gives
the compile errors of undeclared Identifier.

I don't know if it something to do with the ATL configuration or what.

The strange part is that if you hold the cursor above the definition, it
lists the typedef. So, I know it is finding the header file and definition.

I do appreciate the time.

Justin

The solution was found.

It appears that with pre-compiled headers, header includes must come after
StdAfx.h.

Thanks all,

Justin

This is a kind of oddity with the MS compiler. If you're using precompiled
headers, the compiler will simply ignore anything above the #include
"stdafx.h" line (or whatever filename you're using).

You could write, literally:

THIS IS GARBAGE....
#include "stdafx.h"

and you'll get no errors.
