Re: Progress bar for web service?

Sadly, that's the same conclusion I came to, but I keep hoping someone
else will figure out a good way to do this. Specifically, I was
hoping for exactly what you mention: some way of "monitoring the
underlying network transfer status". Oh, well, maybe in 4.0! :-)

Thanks anyway!
Brad.

Hi Brad,

From your description, you have some large objects that will be transfered
in WCF service, and you're wondering how to monitor the transfer progress
of such storng-typed objects without using streaming based transfer model,
correct?

Based on my research, I'm afraid it is not quite supported to get the
transfer status of such strong-type objects in WCF. This is because without
using the streaming model, the only means to detect such transfer status is
through monitoring the underlying network transfer status. However, this is
not exposed(encapsulated internally) in WCF network stack, so far I haven't
found any good interface to inject into it. Therefore, my suggestion is
that you should still consider the streamming + serialization approach.

Sincerely,

I am aware that showing progress for file transfers is relatively easy
with WCF since it can be done using a stream (see
http://www.codeproject.com/KB/WCF/WCF_FileTransfer_Progress.aspx for a
good example). However, I would like to show progress for a strongly
typed object. Is there an easy way to do that? I realize I could do
this using a stream as well, but I would need to handle the
serialization/deserialization myself in this case.

I would think there should be a way of hooking into events at a lower
level than the object transfer, but I certainly don't have a clue how!

As an example, I'd like to call the following method asynchronously
and then provide status updates:

[WebMethod()]
public myBigObject MyCrazyMethod()

Any help would be appreciated.

Thanks!
Brad.
