From the Doc:
Thread.Sleep (Int32) Suspends the current thread for a specified time.
Thread.Sleep (TimeSpan) Blocks the current thread for a specified time.
Do these have the same effect. That is, do the words "Blocks" and Suspends"
mean the same or different things.
Thanks in advance

These are the same.

Are they better to use then

Yes!!
The above will drive the CPU usage of your machine through the roof,
even though it still allows other processes to run.
Thread.Sleep() actually suspends the current thread, so it uses
[virtually] no CPU.

Thanks, good to know

Hi,
The answer, like many is, "This depends (on what you want your application
to do)." However, I'd say, in general, that Sleep should be used.
Application.DoEvents has a lot of overhead, especially in a loop. However,
if you want the message pump in your app to respond to messages during the
delay, then you must use DoEvents (I often put both DoEvents AND Sleep
inside the loop).

Franky,
Are you wanting to block a UI thread? If so then this would be less
bad than Thread.Sleep, but it's still a bad idea. Consider an
alternate approach. Can you explain a bit more about your problem?
Brian
What could be wrong with Thread.Sleep, except that the app becomes
non-responsive??
Thanks

Well, that is the problem. If called on non-UI thread it would be a
different story.
