well i got it working somehow.have attached it.can it be made more elegant
than my code?I have made a similar program for serial port instead of
reading from file it reads from serial port.What if the serial port stops
sending data,i want a GUI error message and control back.the other file has
also been attached(serial one which requires more help).Also i need to
create within this gui another entry which sends data the user enters as and
when he wants to,but the problem is while loop takes contol.
