问题
I've read a few posts here on StackOverflow about task scheduling, but I'm not sure that I get it right. I'm coding (in VB.Net) a backup application, that I'd like to add as a scheduled task (in fact, I'd just like to let the user decide to run it every day at, for example, 3 AM).
I've read posts suggesting to use a windows service for this, but it sounds a bit to much for something as simple as periodically running a task, isn't it?
Could you please advise me on how to simply set a scheduled task in VB.Net? I'm trying to keep my code as lightweight as possible.
回答1:
The best thing is to not write a scheduler, but use the built-in Windows scheduler to run your code.

Note: if you schedule a task to run under an account other than your own, the application may not have access to network drives or some other resources. In other words, there may be some security challenges to work through, particularly for something like a backup app.
If this is just a personal app for backup, my recommendation would be to use XCOPY from a batch file rather than re-inventing the wheel.

As RichardTallent says, don't write your own; instead hook into the Windows scheduler. It's not too difficult.
We used the libraries and examples here and here. Easy to use. Kudos to Eduardo Morcillo and Eric Moreau for showing the way.
