Async processing?

[Alex]

Hello,

I am sort of new to this aspect of .NET so please forgive me if that's a FAQ.

I have a Windows Form that has to perform a lengthy operation when the user clicks a button.
While the operation is in process, the user will not be able to do anything else from the UI but I still want the UI to pump messages (so it can be moved, etc.)

What is the best way to implement it in C#?

Thank you.
Best wishes,
Alex.

Yes, I suspect so. It's certainly helped plenty of other people get to
grips with threading.

I don't see why - you don't need to use a book to learn threading. I
certainly didn't.

If the OP has any further questions, he can always ask them here.

Just to give him source where he can extend his knowlege, coz multitreading
is a vast area.
I take a position that each of use beside just practice should read a couple
books to get basis

Personally I think it's worth trying it with the aid of tutorials and
pages such as mine before spending money on books. It could well be
that there's enough information there for everything the OP wants.

I was considering buying that book but Amazon.co.uk only lists one buying
option - a used copy at 120 GBP! That's 215 USD according to XE.com.

Had a quick look at a couple of other (UK) sites and apparently it's out of
print.

Just a quick explanation.

I am familiar with threading but not with their implementation in the ..NET framework.
Most of my threading experience is under Win32.

The link is helpful but I would like some more insight about the benefits and drawbacks of each method.
Best wishes,
Alex.

What do you mean by "each method" in this case? What alternatives are
you considering?

Hello Jon Skeet [C# MVP],

Maybe he is interesting how is interruption queue and clock interrups realised
in unmanaged code?

Perhaps - I guess we'll have to wait for the detailed questions to know
for sure :)
