Small problem with label or textbox updates

[skid2964]

I have a small, yet annoying problem. When I perform a "FOR" or "DO", I want to update a label or textbox as the loop progresses, for example: if I want to display a percentage done while incrementing a ProgressBar. The problem is that the label or textbox will never update, it wont even clear when I restart the loop!

simplified code example:

The label clear and = i never happen, only the "Done!"

ProgressBar1.Value = 0
ProgressBar1.Maximum = 150

Label1.Text = " "

        For i = 0 To 150

            ProgressBar1.Increment(2)
            i += 1
            System.Threading.Thread.Sleep(5)
            
            Label1.Text = i

        Next

Label1.Text = "Done!"
