Try some like 'ifstream temp(Name,ios::in|ios::binary);' The stream is
opened in text mode
by default (perhaps, this default behavior can be changed) and the first
occurence of
0x26 (to my mind) code is considered as eof. If you insist to read the
stream even if
the ifstream object thinks that it is eof, -1 value is returned and looks as
lightest gray
(white) on the screen.
