大家好，以上是小生从windows程序设计的书里敲过来的，但下面给的错误让小生一直参不透，若有高手指点一二，万分感谢。
--------------------Configuration: SYSMETS3 - Win32 Debug--------------------
Compiling...
SYSMETS3.CPP
d:\program files\microsoft visual studio\myprojects\sysmets3\sysmets3.cpp(2) : fatal error C1083: Cannot open include file: 'sysmets.h': No such file or directory
执行 cl.exe 时出错.
SYSMETS3.OBJ - 1 error(s), 0 warning(s)
小生在百度找的答案是
“呵呵,这个问题很多人问过，蛮经典了。看书的额时候认真点撒，在windows程序设计的前半部分有这个文件的代码.复制它,命名为 'sysmets.h 然后 #include "sysmets.h "”。
其具体的步骤还是不会做。。。。:dizzy: 在学习windows编程时，在参考教程上的程序例时，可能都遇到过类似问题。实际上这是一个需要自己创建的头文件。在windows程序设计的前半部分有这个文件的代码，复制它,命名为'sysmets.h，并把它和源代码放到同一目录下，然后#include"sysmets.h"即可。（注意不是#include<sysmets.h>）
这个问题出现是因为sysmets.h不是VC或SDK的头文件。
首先建立头文件sysmets.h。代码如下：// SysMets.h 头文件
#define NUMLINES ((int) (sizeof sysmetrics / sizeof sysmetrics ))
struct
{
int iIndex;
TCHAR * szLabel;
TCHAR * szDesc;
}
sysmetrics [] =

};而在源文件中写：#include "sysmets.h",而不是：#include <sysmets.h>.此外，网上有些头文件的代码有拼写错误而导致运行出错。在结构struct中的int Index 误写为int iIndex. 谢谢这位版主。。。。{:5_110:} 看看，呵呵。谢谢了啊。。。 谢谢啊！！！！！！！原来得“”
