I too have the sme question- WHICH OS?
If you run the code at startup you can make it in the background and have it chekcing times- this isn't a great solution since how you would do this depends on the OS. It also burns unneccisary proccesor time.
If it's NT or better- the AT command can be used to schedule it.
IF it's Win 98 you can use Task Manager...
I see no reason to develop into the code itself schedules- unless it runs on an OS without a scheduler... WHich goes back to my question
