Converting CString to LPCTSTR

CString has an inbuilt operator which returns a constant pointer to it’s internal data member. It’s called operator LPCTSTR().
So if you write code like this…
CString Str;  
LPCTSTR lpctszStr = Str; 
The compiler replaces above line with a call to operator LPCTSTR(). So will look somewhat like this…
LPCTSTR lpctszStr = Str.operator LPCTSTR(); 
This is the reason why we can directly pass CString objects to SDK functions which takes LPCTSTR arguments.
