Platform: IIS Server, VB.NET for ASP.NET WebForms App

Idea: have a WebForms App on the IIS Server that is reading a MSMQ 
(Microsoft Message Queue). When a message arrives in the queue, take the 
body contents and push it to a web forms control running in a browser.

Attempt: I made this quick and dirty app that does what I stated above. 
The queue was being de-populated successfully by the Receive method but 
the web page would never update with the data. The browser progress bar 
would just slowly go up, and the world just kept spinning...

I want to be able to have the web page open in a browser and just be 
updated from the server. I am new to web forms programming but am skilled 
in VB6/VB.NET Windows Forms Apps.

From what I hear PUSH is a big deal, where PULL is cake.

Anyone with some ideas?
If I have code on the server that has an event triggered in response to a 
message arriving, how can I use that to say - "Hey page, here's some new 
data to display" ?

Thanks in advance
