asynchronous call to web service from a web page

[mimi]

My web service is to update a database. When user clicks on a button on a
web page, it calls web service to update database. With hundred thousand
transactions, it takes 15-20 minutes to update database, eventually it times
out. How do I make an asynchronous call to the web service without needing
a return from call back method. User doesn't have to wait, they just call
the web service then move to other web pages. Thanks

Thanks, but it's for win form and stills need a pointer to call back
function.

I got it. I just need to call BeginXXX the process continues running even
the page finish loading. When the process finished, it writes into a log
file. User can check the log file any time. Thanks

yep,
you can also mark the web service method OneWay.
In this case there is no response at all.

Doing this, you don't need to BeginInvoke_BlahBlahBlah().
It is a big clearer to someone reading the code that this is not just async,
it is actually "fire and forget".
