Thank you for your quick reply!
Yes, similar to that.
In order to give you the exact example, the MySQL table would have columns and rows like:
TIME SCHED PIN# Message text
10:00 111800 This message has to be sent at 10:00
11:56 111546 This message has to be sent at 11:56
14:33 111120 This message has to be sent at 14:33
And so on...
So the program that stays 24 hours connected, will do nothing from 00:00 to 9:59; at 10:00 will send its first scheduled message to a pager by posting a form to a Web Server's CGI.
From 10:01 to 11:55 will do nothing (but connected) and at 11:56 will send its second message... and so on.
Hope I am clear
Thank you very much
