In windows 98 you could do an IrDA to control the pc, but since Win2k they change the way the Windows are handling this device.
It is better to get an ATI Remote Wonder II remote control or something like this PC Control from

I was trying for many days to do an IrDA to work like a remote control, it cost me a lot of time (=money) instead of 50$ for a ready pc remote control!!!
