Hi,

I was just wondering whether someone can explain what the _T relates to in the following code. Haven't been able to find out anywhere.

Code:
CString logMsg;

	if ( FAILED(hr) )
	{
	logMsg.Format(_T("Error determining current User ID (GetOwnUserId failed with error 0x%x)"), hr);
        retUserID = _T("Unavailable");
        return retUserID;
	}
	else;
Any help would be much appreciated.
Thanks,
Steve
