Answer 1

Visual C++ Express Edition don't has built in support for ATL and MFC (CString is an MFC class, implemented as the shared MFC/ATL CStringT class: documentation).

If you really can't afford the Standard Edition, you can rely on this howto to add ATL and MFC support by installing the DDK: http://www.codeproject.com/KB/MFC/MFCinVisualStudioExpress.aspx

You could try TrimLeft(), TrimRight() functions of CString instead.
