如何在win32工程下使用MFC类

把你要用的类的头文件加上：#include <afxmt.h>
#include <afxtempl.h>

我还要说明一下，我的VC下面选定了Ignore All Libraries这个选项

加上类的头文件,需要那个在MSDN里查一下就可以知道是那个文件了。

已经加上该类的头文件，主要是我选择了Ignore All Libraries，没法找到响应的库。另外还出现这样的一个错误：
H:\Program Files\Microsoft Visual Studio\VC98\MFC\INCLUDE\afxv_w32.h(14) : fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>

H:\Program Files\Microsoft Visual Studio\VC98\MFC\INCLUDE\afxv_w32.h(14) :
fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>上面说明Win32 App不能调用MFC。
如果确实要用MFC的函数，看来只能写DLL调用。

我想试试：
（1）把前面的MFC的类库中CTypedPtrList修改为标准C＋＋库的对应的类，但不知道对应的类是什么。此外不知道此法可行否？
（2）不知道除了MFC，同步线程应该使用什么类或者ＡＰＩ函数

进入 Project-->Setting--> C/C++ Page --> Preprocessor definitions 加入 _AFXDLL 并
修改 Project Options，将 /MT 或者 /ML 改为 /MD#include <afx.h>
#include <afxwin.h>         // MFC core and standard componentsextern "C" int WINAPI
_tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
       LPTSTR lpCmdLine, int nCmdShow)
{
       int nRetCode = 0;       if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
       {
              TRACE0("Fatal Error: MFC initialization failed.\n");
              nRetCode = 1;
       }
       else
       {
              // Actual WinMain codes ...              AfxWinTerm();
       }       return nRetCode;
}

先#include <afx.h>
#include <afxwin.h>
再选择rebuild all，输出窗口如下：

按照常理是缺少库文件，我应该加上什么库才好呢？

unresolved external symbol
这个错误明显是文件没包含进来，建议你查查，例如：CPtrList::GetNext在那个文件定义的，加进去，而且前面缺少cobject的定义

仔细研究 <afx.h>，发现应该加入mfc42ud.lib ，mfc42sud.lib ，现在已经下降为2errors，1

谢谢上面各位友情跟贴。
问题已经解决。要点：1、加入相关的头文件，尤其是afx.h
                   2、确保MFC库在CRT库之前被link，可参考微软的文章ID：KB148652
                      查看afx.h文件中库如何链接的部分，选择合理的preprocessor
                       definitions
                   3、多问问题，集思广益to：webber84(***闭关修炼中***)
    我在写一个directshow filter ，是Win32 DLL类型的

    既然是link error，首先想到的不该是头文件没有include吧：）
