help with ATL compiler

[Xavier MT]

Hi, Im compiling a simple ATL Com but I get the following error, and it just
doesn't make sense...

It is a very simple example obtained from a tutorial...

This is the header im using

#pragma once

#define STRICT

#ifndef _WIN32_WINNT

#define _WIN32_WINNT 0x0501

#endif

#define _ATL_ATTRIBUTES

#define _ATL_APARTMENT_THREADED

#define _ATL_NO_AUTOMATIC_NAMESPACE

#include <atlbase.h>

#include <atlcom.h>

#include <atlwin.h>

#include <atltypes.h>

#include <atlctl.h>

#include <atlhost.h>

using namespace ATL;

You should declare a extern variable with type CComCodule like so
in the header file stdafx.h

....

#include <atlbase.h>

extern CComModule _Module;

#include <atlcom.h>

....

Thanks, I tried that but now I get new errors.

Do you know of a source where I can find the instructions to create the COM?
Step by step to see what I am doing wrong...

The error I get is

MyIncludes.h(13) : fatal error C1083: Cannot open include file:
'atltypes.h': No
such file or directory

I set INCLUDE the path, and now I get a new error saying that it needs a
library that already is there

Any ideas?

You are using VC6 which includes ATL3. atltypes.h is shipped with ATL7,
included with VC7 and VC7.1. You don't have it, and the compiler tells
you so.
