谁能帮我看看这个问题
我从网上下了一个程序，编译时提示
C:\Documents and Settings\Administrator\桌面\openfiledlg\StatLink.cpp(179) : error C2065: 'GetSystemWindowsDirectory' : undeclared identifier
执行 cl.exe 时出错.
可我找StatLink.cpp 179行没发现'GetSystemWindowsDirectory' 这个函数，请教一下该怎么改？
StatLink.cpp文件如下：

------解决方案--------------------
加个头文件
#include "Windows.h"
[解决办法]
我们看到的是不是你编译的代码啊
试一试将179行之前加入错误代码，比如
- C/C++ code
int d,e;d-e = 199;
