is it possible to run window service in C#.net without Timer ???

i can not understand , how the service is continuously running in the background?

for E.g. i made one service which update one field value in database table based on condition?

for e.g expiration of status based on date comparing(Todays Date)...

now such condition is not happend regularly...so 1st time i started service ..it works...but now (without rebooting PC) i manually add the date in database which satisfied that condition (entering OLD Date), then it won't work...

but if i use timer Deligate - ElapsedEventHandler , which call that checking condition function on every 10 seconds , then it works.......

so the purpose of window services is to run continuously in background and update databse as per condition......but without timer it is not possible...but i don't want 2 use timer here..

if u have any solutions, then plz give me..

thank you

Ruchir..

I have once Written an Article for Dotnetfunda, the Article is about a Service that kills the Process on your PC(Task Manager) every 5 seconds. i have made an example of the process using a notepad. You can do you database work instead of killing the Process.
