Question

I am checking emailId exists in DB, If Exists
I am looking to create a Ok/Cancel confirmation dialog.
if user say “Ok” I am redirecting to some other form.

My code is :

If emailId = True Then
    If MsgBox("Your email address exists in our database. Click OK to update your   Details.", MsgBoxStyle.Information + MsgBoxStyle.OkCancel, Title:="NJ Golf Resort") = MsgBoxResult.Ok Then
        Response.Redirect("~/articles.asp?a=" & a & "&b=" & b )
    End If
End If

for above code i m getting error :

Showing a modal dialog box or form
when the application is not running in
UserInteractive mode is not a valid
operation. Specify the
ServiceNotification or
DefaultDesktopOnly style to display a
notification from a service
application

Answer 1

function redirect(a,b){
      if(confirm('Your email id is in DB')){
          window.location.href='/articles.asp?a='+a+'&b='+b;
       }
} 

In serverside call the above client side function as

If emailId = True Then
        this.Page.ClientScript.RegisterStartupScript(this.GetType(), "EmailID", String.Format("redirect({0},{1});", aValue, bValue), true);

    /*For Asp.net AJAX use the following code*/
    ScriptManager.RegisterStartupScript(this.GetType(), "EmailID", String.Format("redirect({0},{1});", aValue, bValue), true); 

End If

Note:I have given the C# code.Translate to VB.
