MFC Support in ATL COM Project
I am following this step in order to provide MFC Support in my ATL COM DLL
http://support.microsoft.com/kb/173974
But When in include these files
Code:
#include <afxwin.h> // MFC core and standard components
#include <afxext.h> // MFC extensions
#include <afxdisp.h> // MFC Automation extensions
in Stdafx.h, then I come across this error
Code:
1>d:\Maverick\Projects\CCPM\SRC\WTL80\include\atlctrls.h(1995) : error C3861: 'ImageList_Read': identifier not found
1>d:\Maverick\Projects\CCPM\SRC\WTL80\include\atlctrls.h(2102) : error C3861: 'ImageList_Read': identifier not found

Re: MFC Support in ATL COM Project
This KB is applied to the VC++ versions up to 6.0.
Your version seems to be 8.0.

Right. So what is the solution?
Re: MFC Support in ATL COM Project
What MFC classes do you need to support? For instance, CString is already ATL class...
Re: MFC Support in ATL COM Project
This is an ATL COM Office Addin and I have to implement print preview functionality for it.
Since this is print preview uses MFC Functions so it cannot be directly implemented in an ATL COM Office Addin.
So I guess I might need support for CView and other classes derived from it like CScrollView, so that I can override OnDraw function for the print content and other CView functions for implementing the Preview.
So should I
1) directly implement a CView with my ATL COM Project or
2) Create an MFC Extension DLL that will do this print and preview work?

After doing some experimentation, that link was helpful in getting the things done, in the end the compiler is generating some errors

Re: MFC Support in ATL COM Project
Hi,
If you are creating an ATL app as a DLL, then this is what your stdafx.h should look like...
Code:
// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently,
// but are changed infrequently
#pragma once
#ifndef STRICT
#define STRICT
#endif
#include "targetver.h"
#define _ATL_APARTMENT_THREADED
#define _ATL_NO_AUTOMATIC_NAMESPACE
#define _ATL_CSTRING_EXPLICIT_CONSTRUCTORS // some CString constructors will be explicit
#include <afxwin.h>
#ifndef _AFX_NO_OLE_SUPPORT
#include <afxdisp.h> // MFC Automation classes
#endif // _AFX_NO_OLE_SUPPORT
#include "resource.h"
#include <atlbase.h>
#include <atlcom.h>
#include <atlctl.h>
using namespace ATL;
So, create a test ATL project with MFC support and you will find <afxwin.h> and <afxdisp.h> included and if you remove MFC support from the wizard, these are not included. That should get u started...
Also, when you right click on your project name in the solution explorer and go to the properties, and then navigate to the left side tree view's Configuration Properties -> General node....then on the right side you will see an option "Use of MFC". Make sure that is set to "Use MFC in a shared dll" other wise, even if you include those MFC includes in stdafx.h, compiler will not build against them.
I hope that should be it...and that is if you are using VS 2008 (9.0)...but VS 2005 is not a lot different as far as VC++ IDE is concerned

Bhushan

I am working on an old ATL COM MS Office Addin. Most of the things have already been done, there are numerous property sheets and other controls used. I want to add MFC Support for Printing and Print Previewing.
All the controls being used are a part of MFC as well as ATL. They are defined in
#include<afxwin.h> as well as #include <atlctrls.h>
However their implelentation slightly is different in both the files. Previously all these controls (example CEdit, CStatic etc) were mapped with #include <atlctrls.h> and now with MFC Support they started getting mapped with <afxwin.h> instead of <atlctrls.h>.
Due to this different implementation it started throwing errors. I resolved the ambuguity errors by making slight modification. For example Previously it was..
CEdit m_ctlUsedDuration;I changed it to
WTL::CEdit m_ctlUsedDuration;
Now the compiler is able to recognize that these classes belong to ATL not MFC, however it has spawn to some new errors which I mentioned in this orignal thread.
Yes I changed the setting to USE MFC AS Shared DLL. But those external unresolved errors are still there, in debug mode. When I change the active configuration to "release", the unresolved errors doesn't exist but is one error stating
Code:
1>uafxcw.lib(dllmodul.obj) : error LNK2005: _DllMain@12 already defined in AddIn.obj
1> Creating library Release/CCPM.lib and object Release/CCPM.exp
1>Release/CCPM.dll : fatal error LNK1169: one or more multiply defined symbols found
Can you help me with this??

Re: MFC Support in ATL COM Project
Hey...just try out the stdafx.h file code that I have posted. The targetver.h might contain all the WINVER stuff u r including there...not sure though. It seems that u r unnecessarily defining and undefining windows stuff. Just try removing the windows specific stuff and just keep ATL and MFC stuff and see what happens. Also, try to find out the docs and context of the errors you are getting. Just type in the error number in google and u might get enough to play around.

I am not sure...but as I said, please find out what link errors u r getting and owing to what part of the code. Then find out the required includes and so on...that ofcourse, if it does not work. Also, check the path of the includes in the VC project settings...and check the linker tab for any non standard linker options.
Other than that I can only guess
