Windows程序设计第5版滚动条的问题
我照着《Windows程序设计 第五版》中的SYSMETS3.c程序敲了一遍代码,可在编译的时候老是出错。

#include

#define NUMLINES ((int)((sizeof sysmetrics)/(sizeof sysmetrics[0]))

struct
{
    int    iTndex;
    TCHAR *szLabel;
    TCHAR *szDesc;
}
sysmetrics[]=
{
    SM_CXSCREEN,      TEXT("SM_CXSCREEN"),        TEXT("Screen width in pixels"),
    SM_CYSCREEN,      TEXT("SM_CYSCREEN"),        TEXT("Sxreen height in pixels"),
    SM_CXVSCROLL,     TEXT("SM_CXVSCROLL"),       TEXT("Vertical scroll width"),
    SM_CYHSCROLL,     TEXT("SM_CYHSCROLL"),       TEXT("Horizonta scroll height"),
    SM_CYCAPTION,     TEXT("SM_CYCAPTION"),       TEXT("Caption bar height"),
    SM_CXBORDER,      TEXT("SM_CXBORDER"),        TEXT("Window border width"),
    SM_CYBORDER,      TEXT("SM_CYBORDER"),        TEXT("Window border height")

};

除此之外还有一大堆 “warning: deprecated conversion from string constant to 'TCHAR* {aka char*}' [-Wwrite-strings]”的警告。
 
仔细检查了好几遍也没找出错在哪,求前辈指点。
