I am working on c# 4 windows application
but I need to do something
I have meetng table that have meeting time
but the probelm is that thereis an option to repeat that meeting every 5 days or week or something like this
so what I need excataly is I need to repeat meeting but from sql
because application may not be open all time
so I need something like timer that look at that table from duration to another & check it new meeting is near just send confirm to all people
becuase the application 'll open only when creating new meet or when closing meet
so I can't use timer from c3
any help
