Problem with double clicking on the button ranking system

nir987 · November 23rd, 2011, 03:03 PM

im using vb.net

PHP Code:


			
 Dim button1 As New Button
            button1.CssClass = "btn"

            button1.ID = rc.Fields.Item(4).Value
            button1.Text = rc.Fields.Item(8).Value.ToString
            button1.CommandArgument = "11"
            button1.Width = 50
            button1.Height = 50

            AddHandler button1.Click, AddressOf Button2_Click1

now Button2_Click1 Checks if a cookie exists, if there is updating it if not it creates. If there is subject in cookie then it should skip.
The problem is, if you click full times faster on the button, he just skip and updating the data base so you can fake votes.
PS If I click once, slowly everything works great!

solved!!!!
