hi All,
I dont know if this is possible, so i am asking
Is there a Way to monitor a connection when it is fetching on a web page? I
am providing a status Bar and process to my users so they can see something
is happening?
I would like to do a while loop as in
i+=1
Do while ConnectionState.Fetching
WriteStatusUpdate(writer, "Fetching Records ..." & i.toString(), true)
i+=1
loop
I am currently using the Protected OverRide Render writer to show status,
and would like a little more detail?
Any Suggestions Grealt Appreciated, If you need to review the code, while
lenghty, may help some one else. Code as Follows:
thanks in advance

Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
Dim strmsg As String = ""
' Call the parent render and then flush the contents to get them to the
browser quickly
MyBase.Render(writer)
writer.Flush()
Response.Flush()
' Check to see if btnClear was clicked and that's why we're rendering
If boolStartEvent Then
' Send a "starting operation" message
WriteStatusUpdate(writer, "Checking Connection ...", False)
' Do your long running operation here - provide status at will
Dim TimerEnd As Long = Now().Ticks + 100000000
While Now().Ticks <= TimerEnd

strmsg = checkConnection()

This will not work because the flushing to the browser only occurs after the
main thread is processing. You will not see any incremental updates.
To create a status bar, you need to do so on a separate thread. While one
thread does work, the other thread updates the user interface. About the
easiest thing you can do to get this to work if you don't want to thread is
to cause the page to refresh itself with a meta refresh tag every so often.
At this refresh time, you will update your status bar appropriately.
