strange problems with SEND

[Bob Sneidar]

This got me thinking, I've pondered a way to run scheduled tasks, and how I would go about it. I think what I would do is have a faceless standalone that once launched sent a command in time every second, or 5 seconds or whatever, and the handler would then check a list or a database for tasks whose datetime was prior to the current time, and were flagged pending. 

I would then probably through socket communication attempt to trigger the task to my actual application, and if successful mark the task as completed. If the socket comm failed, I would simply do nothing and issue another send in time. 

The advantage of using a dedicated app is that multiple applications could take advantage of it. A new app could simply register with the timer app again through sockets, and each task would store the name of the registered app in the task, so each app would only get it's own tasks. 

Probably more than what you want to do though. At the very least you could implement this in app.
