使用_stscanf和_sntprintf进行GUID和字符串互相转换

#include <stdio.h>

BOOL LPCTSR2GUID(LPCTSTR szGUID, GUID &Guid)
{
memset(&Guid, 0, sizeof(Guid));
int nRet =
_stscanf(szGUID,
_T("%08x-%04x-%04x-%02x%02x-%02x%02x%02x%02x%02x%02x"),
&Guid.Data1,
&Guid.Data2,
&Guid.Data3,
&Guid.Data4[0], &Guid.Data4[1],
&Guid.Data4[2], &Guid.Data4[3], &Guid.Data4[4], &Guid.Data4[5], &Guid.Data4[6], &Guid.Data4[7]
);
return (nRet == 11)? TRUE : FALSE;
}

LPCTSTR GUID2LPCTS(GUID Guid)
{
static TCHAR szBuf[65] = {0};
_sntprintf(szBuf, 64, _T("%08X-%04X-%04X-%02X%02X-%02X%02X%02X%02X%02X%02X"),
Guid.Data1,
Guid.Data2,
Guid.Data3,
Guid.Data4[0], Guid.Data4[1],
Guid.Data4[2], Guid.Data4[3], Guid.Data4[4], Guid.Data4[5], Guid.Data4[6], Guid.Data4[7]
);
return szBuf;
}

LPCTSTR szGUID = _T("E6F62D77-F3AF-42AA-8C04-C8F7F0FAC85E");

GUID tmpGuid = {0};
LPCTSR2GUID(szGUID , tmpGuid);
TRACE( _T("%s"), GUID2LPCTS(tmpGuid));
