Would you please be more detialed on how to use fstream class to implement my purpose.

// Another simple example - Your class should probably have a constructor! :)

Yes, i actually had problem with string item in the struct. Actually, I used char Name[20]. However,
the length of the contents is varying. 20 is the max. length of the Name attribute of objects.
Hence, memory was wasted by objects with a Name less than 20 characters. How to solve this
problem.

would like to be able to overlay a timer (hours:minutes) on top of my system tray icon, but due to the default size (16x16), there simply isn't enough room to display the timer in a visually appealing manner.
