I am coding in c++ windows.
INT64 dirID = -1;
CString querySQLStr = _T("");
querySQLStr.Format(L"select * from ImageInfo where FolderPath=%64d;", dirID);
querySQLStr always like this:
select * from ImageInfo where FolderPath= 1214;
is it right to use %64d? Many Thanks
I don't have a windows machine handy to test this on, but I think CString should accept this:
querySQLStr.Format("%I64d", dirID);
It's probably worth noting that this is windows specific, but since you're using CString I guess that's okay.
i think you need to try this:
__int64 val;
......
ParamVal.Format( _T("%d{I64}"), val);
%lld和%I64d也同样有效。
strCode.Format(_T("Code = %lld, Result = %I64d \n"),lCode,lResult);
