The STL string class has a c_str() method that will give you such an object.
With vector<char> you would probably use &v[0].

Subject: RE: [Dev-C++] Reading from text file
I was using these two functions to put text into the edit control:
SendMessage( GetDlgItem(main, IDC_MAIN_EDIT), EM_SETSEL, (WPARAM)nLength,
(LPARAM)nLength );
SendMessage( GetDlgItem(main, IDC_MAIN_EDIT), EM_REPLACESEL, (WPARAM)FALSE,
(LPARAM)inLine );
inLine was of type char*, the argument that the function will accept but how
can I do it with the vector<char> or string type?
