crudely written code:
Known is handfull, Unknown is worldfull
Code:
<%@ import namespace="System.Threading"%>
<script>
function ShowProgress(Current,Total)
{
document.getElementById("ProgDiv").innerHTML=(Current/Total)*100+"%"
}
</script>
<body>
<div id="ProgDiv"></div>
</body>
<script runat="server">
Shared waitTime As New TimeSpan(0, 0, 1)
Dim newThread As New Thread(AddressOf Work)
Shared Sub Work()
Thread.Sleep(waitTime)
End Sub
</script>
<%
dim i as integer
newThread.Start()
for i=1 to 20
%>
<script>ShowProgress(<%=i%>,20)</script>
<%
response.flush()
newThread.sleep(1000)
next
response.write("DONE")
%>Known is handfull, Unknown is worldfull

Yes, I took your code and just made it work as a single page code. It needed a little tweaking.
Now I'm not the brightest bulb on the tree but I do not understand how this will work with codehehind. If you update your value in the codebehind that the javascript is to use then you would have post back and forth many times. How else would the javascript get the new value? Please excuse my ignorance may be you can help me understand your code.

Another alternative is to get the page to refresh to update the status e.g.
If this could be coupled with XMLHTTP, then you could implement a real-time status that didn't refresh the whole page.
