How can I convert CString to LPCTSTR ?

You don't need to. CString already contains `operator LPCTSTR'.
Just pass CString object where LPCTSTR is expected.

you mean CString and LPCTSTR are same thing?

for a function that expect LPCSTR parameter, I can still pass in a
CString?

somefuncion (LPCTSTR string)

CString cc = "aaa";
somefunction ( cc );

No, class CString has a user-defined conversion operator to LPCTSTR.

Yes, that works, exactly because of the above mentioned conversion.

No, they are different types. But CString knows how to convert
itself to LPCTSTR if required.

You mean LPCTSTR, not LPCSTR, yes?

Yes, this will work. Also, you should use _T() macro if you want
to work with TCHAR's and CString:

CString cc = _T("aaa");
