CString Left( int nCount ) const;
throw( CMemoryException );
A CString object containing a copy of the specified range of characters. Note that the returned CString object may be empty.
The number of characters to extract from this CString object.
Extracts the first (that is, leftmost) nCount characters from this CString object and returns a copy of the extracted substring. If nCount exceeds the string length, then the entire string is extracted. Left is similar to the Basic LEFT$ function (except that indexes are zero-based).
For multibyte character sets (MBCS), nCount refers to each 8-bit character; that is, a lead and trail byte in one multibyte character are counted as two characters.
The following example demonstrates the use of CString::Left.
// example for CString::Left CString s( _T("abcdef") ); ASSERT( s.Left(2) == _T("ab") );
