Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        While NextFrame <= numericUpDown1.Value
            Controls("Label" & NextFrame.ToString()).BackColor = Color.Yellow
            NextFrame = NextFrame + 1
        End While
    End Sub

color.yellow is working before sleep(2000) but we can't visualize that yellow color. What is the solution to get yellow color as output?

1 solution

Try adding a Refresh() method to your control before entering the sleep().
The problem is that during sleep the whole thread is frozen even the message loop and controls dispatching don't works.
Maybe you wan use a different method to wait (i.e. using a timer).
