Hi,

I am trying to use CoInitializeEx but VC++ 6.0 compiler always complaining
error C2065: 'CoInitializeEx' : undeclared identifier.

According to MSDN
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/com/htm/cmf_a2c
_5iyg.asp),
CoInitializeEx is in "ole32.lib" and I have it in my "Project -> Settings ->
Link -> Object/library modules".

Is there anywhere else I forgot to include?

Please advice, thanks!
-P

Somewhere before that ill-fated usage, write
#define _WIN32_WINNT 0x0400
#include <ole2.h>

You might want to study the following screen-scrape and
think about the implication a little bit.
=====================================
[C:\tmp]

> pushd \Programs\DevStud.NET.2003\Vc7\PlatformSDK\Include\

[C:\Programs\DevStud.NET.2003\Vc7\PlatformSDK\Include]

> findstr CoInitializeEx *.h

...
ObjBase.h:WINOLEAPI CoInitializeEx(IN LPVOID pvReserved, IN DWORD dwCoInit);

[C:\Programs\DevStud.NET.2003\Vc7\PlatformSDK\Include]

> findstr /i objbase.h *.h | findstr include

...
Ole2.h:#include <objbase.h>
...

======================================

Your error message came from the compiler.
Your settings shown above affect the linker.
Those tools are distinctly different and you should
learn to distinguish them to help sort out problems
of this nature on your own.
