I have an event function, Timer_Elapsed() that executes response.redirect, however, no action is taken when the line of code is executed.

The page load event of this page starts a timer as the last thing it does. I do this because the page must execute a long running query (13 seconds) and I want the page to render itself before the query is kicked off, otherwise the user is looking at a blank screen for 13 seconds before anything is presented. So far tuning the query hasn't yielded acceptable results yet. When the query returns, I store the dataset object in a session variable and redirect to the next page where the results will be rendered for the user's next action.

The application queries an error log table in Oracle to get interface errors for a number of interfaces for easy monitoring of the integrations.

The code looks like this:

   Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
        . do initialization stuff here
        .
        .
        StartTimer()

    End Sub

   Private Sub StartTimer()
        Dim Timer1 As System.Timers.Timer = New Timer
        Timer1.Interval = 1000
        AddHandler Timer1.Elapsed, AddressOf Timer1_Elapsed
        Timer1.AutoReset = False
        Timer1.Enabled = True
    End Sub

    Private Sub Timer1_Elapsed(ByVal sender As System.Object, ByVal e As System.Timers.ElapsedEventArgs)
        GetErrorSummary(txtDateFrom.Text, txtDateTo.Text)
        Response.Redirect("ErrSummary.aspx", False)
    End Sub


Thanks,

You might want the timer function in javascript and not in the code-behind ... as the server has no way of starting a client interaction.

Thanks Vadivel!

I'm from the VB6 world and haven't used Javascript much yet. I was able to use the Page.RegisterStartupScript function to embed a function to click a submit button that kicked off the database query and response.redirect. I could have still kicked off the timer but that seemed more complex than necessary.

Do you know if a Javascript function can call a code-behind function? If so, what's the syntax?

Thanks again!



Thanks,
