To fix this problem, make your stdafx.h file look like this:
// Modify the following defines if you have to target a platform prior to the ones specified below.
// Refer to MSDN for the latest info on corresponding values for different platforms.
#ifndef WINVER // Allow use of features specific to Windows 95 and Windows NT 4 or later.
#define WINVER 0x0501 // Change this to the appropriate value to target Windows 98 and Windows 2000 or later.
#endif
#ifndef _WIN32_WINNT // Allow use of features specific to Windows NT 4 or later.
#define _WIN32_WINNT 0x0501 // Change this to the appropriate value to target Windows 98 and Windows 2000 or later.
#endif
#ifndef _WIN32_WINDOWS // Allow use of features specific to Windows 98 or later.
#define _WIN32_WINDOWS 0x0501 // Change this to the appropriate value to target Windows Me or later.
#endif
#ifndef _WIN32_IE // Allow use of features specific to IE 4.0 or later.
#define _WIN32_IE 0x0500 // Change this to the appropriate value to target IE 5.0 or later.
#endif

解决方法：从别的地方或者网络上下载这个库文件，放入VS安装目录里的VC\lib目录即可
