Your fundamental error is in thinking LPCTSTR is a sensible data type. You should be using CString. CString s; s = ...; CString truncated_s(s.Left(n)); CString rest_of_s(s.Mid(n + 1)); In MFC, it RARELY makes sense to be using LPCTSTR for any data in your own program. It is something to be used under rare and exotic circumstances. In the worst case, I might write a couple LPTSTR declarations in a program, mostly to get writeable buffers for API calls. But I would never consider LPCTSTR as a reasonable data structure for ordinary work. Or LPTSTR, either. If you are seriously using LPTSTR/LPCTSTR, you should reconsider how you are writing code. joe On Fri, 5 Mar 2010 07:42:53 -0800 (PST), Luigino <npuleio(a)rocketmail.com> wrote: >Hello everyone, > >I'm trying to truncate with a certain LPCTSTR string to n position and >get another LPCTSTR variable truncated by that n position.... > >Is it possible?
