Drawing lots of images quickly with for statment

[Gussy]

Hi,

The code below draws anywhere from 1 to 75 of these images one after another,
its basically like with itunes and wmp where you have the lines / green bit on the bit that shows you how much song has played.

For i As Integer = 4 To CType(((Pos * MyBase.Size.Width) / 100) - 4, Integer) Step 2
    MyBase.CreateGraphics.DrawImage(My.Resources.track_lines, i, 0, My.Resources.track_lines.Width, My.Resources.track_lines.Height)
Next

I need a better way to do this because at the moment whenever they change they jitter and flash.

Thanks for your help,

Cheers,
Gussy
