//错误的提示就是
// iIndex ;
szLable ;
szDesc
这几个变量未定义
郁闷了
//system.h就是我前面那个
头文件的名字
我在1楼贴出来的

TextOut(hdc,0,cyChar * i,
sysmetrics[i],szLable,
lstrlen(sysmetrice[i],szLable));
这里是不是应该是
TextOut(hdc,0,cyChar * i,
sysmetrics[i].index,sysmetrics[i].szLable,
lstrlen(sysmetrics[i].index,sysmetrics[i].szLable));
sysmetrics[i],szLable,
lstrlen(sysmetrice[i],szLable));
这里是不是应该是
TextOut(hdc,0,cyChar * i,
sysmetrics[i].index,sysmetrics[i].szLable,
lstrlen(sysmetrics[i].index,sysmetrics[i].szLable));

你得给结构起个名字吧。sysmetrics 看意思应该是个变量名
struct Mystruct
{
int iIndex ;
TCHAR *szLable ;
TCHAR *szDesc ;
};
Mystruct sysmetrics []
{
}
{
int iIndex ;
TCHAR *szLable ;
TCHAR *szDesc ;
}
