Have you tried suggestion in my previous posting ?

Scenario:
I have two web users. If user 1 makes a change to an Application server state variable, how do I notify user 2 about the new info without doing constant javascript polling in a timer using Ajax, which is what I am doing right now?
I would like to make this more efficient because the contant polling seems expensive to me. Any ideas?
Thanks!

AJAX is the only way you can send info to a user who does not themselves click on a link, or go to a new page.

Can you narrow down where the problem is occurring? It is rather difficult with the way the code is formatted in your post. Try to have it inside < pre > / < /pre >tags to preserve the indentation for the most part

Why? I doubt it is possible without page postback. Anytime I've done web stuff that required populating a control after another control had some user action performed on it, I've always had to run the page through again but the next time, conditional branches guiding the behind the scenes code based on that user action.
I don't know much about Ajax, but maybe that could help.

Friends,
I am working on a Product which is migrated from Visual Basic 6.0 to .NET 2.0.
The product uses ADO Connection object. And the connection object is using Reshape Name Property (MSDataShape) and SHAPE method to concatenate set of tables.
Right now, the DB Connection is using Standard Login Method. We are trying to implement Integrated Security Login. This MSDataShape does not supporting Integrated Security. Any one has solution without removing MSDataShape to achieve Integrated Security?
Current ConnectionString,
"Provider=MSDataShape; Data Provider=MSDASQL; DSN=MyDSN; UID=user1; PWD=pass;"
I tried as,
"Provider=MSDataShape; Data Provider=MSDASQL; DSN=MyDSN; Integrated Security = SSPI"

Have a wizard on a page, with a few fields and validators for some of them.
Also, have a login control (the standard one that comes in asp.net). Well, if I try logging in, the validators on the wizard fire up and basically I cannot login unless the fields in teh wizard are filled. Pretty funny, but any idea how to, sorta group the validators, so when I use the login control it does _not_ check the wizard's validators?
Thanks in advance.
