Bar Level as percentage

[MrPike]

Hello AHMI world.  I want to use the Bar Level as a percentage rather than a raw value.  What I noticed is that if the value goes beyond the max value, the text will move off the end of the control and not be visible.  There are times my value will go beyond 100% during overloads and I want the value to still be seen.  I was wondering how I can change the text to be fixed in the center of the bar level and not follow the fill line?  Similar to the attached pic,  Thanks.

I did a little "googling" and came across this code which does paint the value in the center of the control, however it seems to flicker on/off so fast that it can hardly be seen.  Is there a trick to keep this visible?

 thanks


    Private Sub BarLevel1_ValueChanged(sender As Object, e As EventArgs) Handles BarLevel1.ValueChanged
        percent = CInt(Me.BarLevel1.Value)
        Using gr
            gr = BarLevel1.CreateGraphics

            gr.DrawString(percent & "%", Me.Font, Brushes.Black, _
                          Me.BarLevel1.Width / 2 - (gr.MeasureString(percent & "%", SystemFonts.DefaultFont).Width / 2.0F), _
                          Me.BarLevel1.Height / 2 - (gr.MeasureString(percent & "%", SystemFonts.DefaultFont).Height / 2.0F))

           End Using

    End Sub
