Hi,

I want to mix an MFC application with WTL but when I compile I get this error:

d:\WTL80_7108_Beta1\include\atluser.h(407) : error C2039: 'CString' : is not
a member of 'ATL'
d:\WTL80_7108_Beta1\include\atluser.h(561) : see reference to class
template instantiation 'WTL::CMenuT<t_bManaged>' being compiled
d:\WTL80_7108_Beta1\include\atlgdi.h(2573) : error C2039: 'CString' : is not
a member of 'ATL'
d:\WTL80_7108_Beta1\include\atlgdi.h(3284) : see reference to class
template instantiation 'WTL::CDCT<t_bManaged>' being compiled
d:\WTL80_7108_Beta1\include\atlgdi.h(2573) : error C2039: 'CString' : is not
a member of 'ATL'

Is it possible to mix MFC and WTL?

Thanks.

I believe it is.

In fact, WTL is built on top of ATL, and since VS2003, it seems that
MFC and ATL have been mixed together (in fact they share also some
classes like the new CString template - note that VS6 MFC CString was
not a template).

What compiler are you using? Maybe are you using an old compiler that
does not support modern WTL templates?

MrAsm a écrit :

Here is how I do it :

Declare this just after pragma once in stdafx:

#pragma once

#define _WTL_FORWARD_DECLARE_CSTRING
#define _WTL_NO_AUTOMATIC_NAMESPACE
//#define _WIN32_WCE_AYGSHELL 1
#include <atlbase.h>
#include <atlapp.h>
#include <atlwin.h>
#include <atlddx.h>
#include <atlctrls.h>
#include <atlctrlx.h>
#include <atlframe.h>
#include <atldlgs.h>
#include <atlscrl.h>
#include <atlmisc.h>

//#ifdef WIN32_PLATFORM_WFSP
//#include <tpcshell.h>
//#endif
//#include <atlwince.h>

//-----------------------------------------------------------------------------
// MFC STUFF

Hi,
I'm using VC++ .NET2003 and WTL 80_7180 Beta 1.

Maybe this article will help:

I know this article. But I'm getting those errors before I use any WTL class.
Below is my stdafx.h file. The rest of project is just a plain Wizard
generated MFC application.

#define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers

have you tried with WTL71? IIRC WTL75 was for VS2005 and WTL71 for
VS2003

You don't seem to read my post.

First check you use a recent WTL version (the last is 8)
then put this in your stdafx.h BEFORE MFC stuff. I insist on before!

#pragma once
//-----------------------------------------------------------------------------
// WTL STUFF
//-----------------------------------------------------------------------------
#define _WTL_FORWARD_DECLARE_CSTRING
#define _WTL_NO_AUTOMATIC_NAMESPACE

#include <atlbase.h>
#include <atlapp.h>
#include <atlwin.h>
#include <atlddx.h>
#include <atlctrls.h>
#include <atlctrlx.h>
#include <atlframe.h>
#include <atldlgs.h>
#include <atlscrl.h>
#include <atlmisc.h>

//-----------------------------------------------------------------------------
// MFC STUFF
//-----------------------------------------------------------------------------

//#define _ATL_CSTRING_EXPLICIT_CONSTRUCTORS // some CString
//constructors will
//be explicit

// turns off MFC's hiding of some common and often safely ignored warning

#define _AFX_ALL_WARNINGS

#include <afxwin.h> // MFC core and standard components

#include <afxdtctl.h> // MFC support for Internet Explorer 4 Common
Controls

#include <afxcmn.h> // MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT

#include <atlbase.h>
#include <atlstr.h>
#include <atlapp.h>

#include <shellapi.h>

#include <atlwin.h>

Hi mosftet,

I do as you suggested. Now I'm getting these error:

c:\Arquivos de programas\Microsoft Visual Studio .NET
2003\Vc7\atlmfc\include\afxv_w32.h(18) : fatal error C1189: #error :
WINDOWS.H already included. MFC apps must not #include <windows.h>

I must be missing something.

My stdafx.h file now looks like:

#pragma once

#define _WTL_FORWARD_DECLARE_CSTRING
#define _WTL_NO_AUTOMATIC_NAMESPACE
//#define _WIN32_WCE_AYGSHELL 1

#include <atlbase.h>
#include <atlapp.h>
#include <atlwin.h>
#include <atlddx.h>
#include <atlctrls.h>
#include <atlctrlx.h>
#include <atlframe.h>
#include <atldlgs.h>
#include <atlscrl.h>
#include <atlmisc.h>

#ifndef VC_EXTRALEAN

#define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers
#endif

// turns off MFC's hiding of some common and often safely ignored warning
messages

#include <afxwin.h> // MFC core and standard components
#include <afxext.h> // MFC extensions
