int turn LPCTSTR

Most provincial thing, is to use CString transit at:

1 2 3 4

int  i = 10; CString str; str.Format(_T( "%d" ),i); LPCTSTR  pStr =  LPCTSTR (str);

Further, the _stprintf more convenient, and automatically adapt the character set, but do need to apply a static memory and converted (as LPCTSTR mean Const constant TCHAR sub adaptation STR character string pointer).
