Disable input during processing.

[.paul.]

Well, if you're still looking I think you just have to reference the buttons directly in code:

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Button1.Enabled = False
        System.Threading.Thread.Sleep(1000)
        Button1.Enabled = True
    End Sub

I tested this and as soon as I clicked Button1 it became disabled for 1 second

try harddisk's code. seems to be a vs bug
