Is there one API to handle the Task Scheduler in XP and Vista?

I have a couple applications that I would like to be able to add scheduled tasks from within them. I've been Googling for how to add tasks in both XP and Vista.

Automatically starting Windows Sound Recorder

My division has been tasked with recording the morning presentation audio for future use, using the built-in Windows Sound Recorder. Because of human nature, we don't always remember to start it on time. Windows doesn't have a built-in equivalent to the Unix cron function.

Task Schedule Refusal

Although some might not think of it as programming related, it certainly is. The task Scheduler is a program. It's launching a process that I have written. Stating that it's a common problem is not very helpful. I've set up my own backup procedures, both on a Windows xP machine at home, and on several at the office, where I use the...

data structures for scheduling workflow?

I'm wondering what kind(s) of data structures / algorithms might help facilitate handling the following situation; I'm not sure if I need a single FIFO, or a priority queue, or multiple FIFOs.
