Hi all,

Is there anyway to track the progress of a Async Web Service Call (BeginXXX
/EndXXX type)?

In my long running web service, I want to flag certain stages of
completion, is there a way to relay this data back to the calling function?

Thanks.

In checking the documentation for VS2005, I didn't see anything that would
help. But, like you, I would like the idea of being able to have a progress
bar to provide user feedback.

I was wondering the same... This post here suggests you can pass
delegates into the call... I'd be very suprised, but I haven't tried it:

progress%26hl%3Den%26lr%3D%26safe%3Doff%26sa%3DN%26tab%3Dwg

I was playing with an idea where each call had a guid... This could be
passed to a second web service that returned the status/percentage...
This could be called every few seconds to update the progress, until the
original call completes. Sounds a bit ott if your call isn't running
into minutes, but I've not seen a simpler method :(
