CMap中用自定义的结构做value和用CString做Key编译出错

[abesky]

struct shpFd{
CString sLayFdname;
CString sFdType;
int iLen;
BOOL bSpecChange;
shpFd(){
sLayFdname = "";
sFdType = "";
iLen = 0;
bSpecChange = FALSE;
}
shpFd(shpFd &des)
{
sShpFdname = des.sShpFdname;
sLayFdname = des.sLayFdname;
sFdType = des.sFdType;
iLen = des.iLen;
bSpecChange = des.bSpecChange;
}
shpFd& operator = (const shpFd &des)
{
sShpFdname = des.sShpFdname;
sLayFdname = des.sLayFdname;
sFdType = des.sFdType;
iLen = des.iLen;
bSpecChange = des.bSpecChange;
return * this;
}
BOOL operator==(shpFd fd) const throw()
{
return (sShpFdname == fd.sShpFdname&&
sLayFdname == fd.sLayFdname&&
sFdType == fd.sFdType&&
iLen == fd.iLen&&
bSpecChange == fd.bSpecChange);
}
BOOL operator!=(shpFd fd) const throw()
{
return (sShpFdname != fd.sShpFdname||
sLayFdname != fd.sLayFdname||
sFdType != fd.sFdType||
iLen != fd.iLen||
bSpecChange != fd.bSpecChange);
}

};


定义map时
CMap<CString, CString, shpFd, shpFd> shpFds;

编译报错

怎样满足CString做Key 自定义的结构做value得map？

[teli_eurydice]

CMap<CString,yourSturct>

[abesky]

CMap<CString,yourSturct>??行吗你试试

[oyljerry]

CStringMap

[abesky]

CMap<CString, LPCTSTR, shpFd, shpFd> shpFds;

[abesky]

靠搞定 还可以用CMapStringToPtr 或是 CMapStringToOb
