MFC以及BCG库均使用静态库链接方式（不知其它方式是否也有可能出现……），解决方法如下：
在stdafx.h中加入
#define COMPILE_MULTIMON_STUBS
#include <multimon.h>

您好，我现在也遇到了这个问题，你是怎么解决的啊？我在stdafx.h中加入#define COMPILE_MULTIMON_STUBS#include 后，又出现了更多的错误，1>GridCtrl.obj : error LNK2005: _xGetSystemMetrics@4 already defined in stdafx.obj1>GridCtrl.obj : error LNK2005: _g_pfnGetSystemMetrics already defined in stdafx.obj
试试把这段移到stdafx.cpp里
