I have a backgroundworker thread that I need to check some data for me every
6 hours or so. I can start the thread and do the check with great success,
but I only need this thread to check every six hours. I tried the timer
control, but that is clumbsy. I was wondering if I should use the thread to
keep track of the system time and subtract the time from last check and when
it hits 6 hours or greater run the process, or is there a better way? I
really don't want this thread just processing time when it is not needed.
Any suggestions?

You should use a timer - but .NET has 3 different timers (each with a
slightly different use):

Also you might want to build your app as a service - so that it can run
continously.

You may also want to track the last runtime - so if the app crashes, it can
pickup where it started up last.
 
John,

You mean that you want to use the instruction.

threading.thread.sleep(milliseconds).

As Spam Catcher already wrote. This is in my opinion a typical windowservice

I hope this helps,

I got it. I just set the sleep as shown below. Then recall the DoWork sub
from the RunWorkerCompleted Sub. This gives me the six hours I need. A
windows service would be more combersome as we don't want to install
services on all the computers. This does great. Then I use delegates to
interact with the program. Thanks for the help.

System.Threading.Thread.Sleep(System.TimeSpan.FromHours(6))
