  : hey I am trying to make it so when my program is minimized it will flash on system can anyone help me?
  
  Flash on the task bar, or in the system tray? If it's in the task bar, there is an API call for that. I don't know it off-hand though.
  
  If it's in the system tray, then just have a timer change the icon of the system tray component between your programs icon and something else (maybe no icon). If you look, you could probably find a system tray component that has flash capability built in.

  dont have yahoo, but for the taskbar there was something like FlashWindow(hwnd) which will make the window button on taskbar to go blue (orange on xp blue theme) and back to normal after second call
