Pausing a process without holding OS

[John]

Hi

I need to add pauses in-between processes in my app to give time to other
users/processes on the network. Is there a way to pass control to OS for a
specified time (say 15 seconds) to delay my app but at the same time not
blocking OS's processor cycles?

Thanks

Regards

Threading.Thread.Sleep(15000)



If the thread has a UI, it's better not to Sleep because it locks the UI.
- Instead you should set a Timer and do whatever in 15 seconds
- Or, do whatever has to be done in another thread (including Sleep). Then I
also suggest not to sleep for 15 seconds but only max 1 second (for example)
in a loop in order to be able to react to cancel requests.

Application.DoEvents() is probably the easiest way. You need to disable all
your controls so you don't get cascading events.

For example,
Me.Enabled = False
Application.DoEvents()
Me.Enabled = True

I wouldn't recommend DoEvents. I gave the reasons some weeks ago (can be
searched for). In (very) short: If I want to do two things at the same time,
I use two Threads. That's what they are made for. If I have two threads,
there is no reason to use DoEvents.
