Async Delegate question

[Viet]

Can I use Async delegates to do infinite polling in vb.net?

 

[Adam Goossens]

I don't exactly understand what you mean. By "infinite polling", do you
mean sitting in a loop and polling indefinitely (maybe sleeping once in
a while), or polling once every X seconds for ever?

If it's the former, then yes, you can. Fire the polling method using an
async delegate to run it on a second thread.

If it's the latter, no, you can't directly - you'll need to use a
System.Threading.Timer to trigger the poll once every X seconds.

Actually, its the former: fire the polling method by sitting in a loop and
polling indefinitely. The code is I used is:
if objectIASyncResult.iscompleted = true then
'do something

but everytime I execute it, it executes once. Is there any code examples for
this?
THanks,
