Windows下动态库的编译以及调用
2020-12-13 05:49
标签：style blog color os io 文件 for ar 1.MFC下生成动态库 1>显式调用 在.cpp文件里添加接口函数 在.def文件里标示导出接口 编译即可生成动态库 在.exe里调用 在头文件里添加 Button事件 然后将相应的.dll和.lib拷贝到相应目录即可。 2>隐式调用 在头文件里添加 1 typedef int (*PFUNC)(int,int); 1 HMODULE hDllLib; 2 PFUNC m_pSum; 3 PFUNC m_pSub; 在BOOL CTestDlgDlg::OnInitDialog()里添加 其他相应代码 2.Win32下动态库生成及调用 动态库头文件里添加 .cpp文件里添加 编译即生成动态库 调用 在.exe头文件里添加 其他相应文件 以上代码通过测试！ Windows下动态库的编译以及调用,搜素材,soscw.com Windows下动态库的编译以及调用 标签：style blog color os io 文件 for ar 原文地址：http://www.cnblogs.com/wanzaiyimeng/p/3885653.html1 int sum(int a,int b)
