手头上有个自己写的类，比较复杂，请问怎么封装到DLL里面去

[teli_eurydice]

这个类是基类，继承自CObject，MFC 调用，会有其它类继承这个基类

[jerry]

那只能做成 扩展 MFC DLL

[teli_eurydice]

不要太复杂，呵呵

[byf2002]

导出类就行了

[teli_eurydice]

有例子给我看看吗，对这个不是很了解阿，郁闷，呵呵

[caesar22]

必须使用扩展的MFC DLL了。

使用AFX_EXT修饰你的类就可以

//给你一个最简单的例子：用的时候，先用向导生成一个MFC Dll（扩展MFC DLL）：

// MfcDll.cpp : Defines the initialization routines for the DLL.
//

#include "stdafx.h"
#include <afxdllx.h>

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif




static AFX_EXTENSION_MODULE MfcDllDLL = { NULL, NULL };

extern "C" int APIENTRY
DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
// Remove this if you use lpReserved
UNREFERENCED_PARAMETER(lpReserved);

if (dwReason == DLL_PROCESS_ATTACH)
{
TRACE0("MFCDLL.DLL Initializing!\n");

// Extension DLL one-time initialization
if (!AfxInitExtensionModule(MfcDllDLL, hInstance))
return 0;

// Insert this DLL into the resource chain
// NOTE: If this Extension DLL is being implicitly linked to by
// an MFC Regular DLL (such as an ActiveX Control)
// instead of an MFC application, then you will want to
// remove this line from DllMain and put it in a separate
// function exported from this Extension DLL. The Regular DLL
// that uses this Extension DLL should then explicitly call that
// function to initialize this Extension DLL. Otherwise,
// the CDynLinkLibrary object will not be attached to the
// Regular DLL's resource chain, and serious problems will
// result.

new CDynLinkLibrary(MfcDllDLL);
}
else if (dwReason == DLL_PROCESS_DETACH)
{
TRACE0("MFCDLL.DLL Terminating!\n");
// Terminate the library before destructors are called
AfxTermExtensionModule(MfcDllDLL);
}
return 1; // ok
}

//总共3个文件，你将向导生成的文件用这边第一个文件内容替换掉，加入其他两个文件，编译：
//调用的时候：将.DLL文件放入调用程序的exe所在目录或系统目录
//将.lib文件和TestClass.h文件放在调用程序得项目文件夹即和其它头文件在同一个目录
//然后
//
#include "TestClass.h"
//就可以用了
