Does this code helpful?

LPTSTR pBuffer = szString.GetBuffer( 10 );
// Directly access CString buffer ad use as TCHAR
_tcscpy_s( pBuffer, 10, "String" );
szString.ReleaseBuffer( );

I would not recommend the usage of GetBuffer() method for the sake of copying the string content to another TCHAR* .

Which means two things: 1. You must never forget to call ReleaseBuffer() after you're done with it. 2. All the member functions on your CString object are *not* guarenteed to work perfectly between the GetBuffer() and ReleaseBuffer() calls.

In fact he took care about both the issues.

And you agreed GetBuffer() isn't the best way around to do it
