Graphics and Double Buffering

[Simon Jefferies]

Hello,

I am using the Paint event to draw graphics, but I am getting annoying flickering. Is there anyway to perform double-buffering?

I have looked at creating a bitmap, but is limited in what I can do with it.

Any ideas?

Thanks

Simon,
Include the following in your Form or Control's constructor.

' Stop the flicker
Me.SetStyle(ControlStyles.UserPaint, True)
Me.SetStyle(ControlStyles.DoubleBuffer, True)
Me.SetStyle(ControlStyles.AllPaintingInWmPaint, True)
Me.SetStyle(ControlStyles.ResizeRedraw, True)
Me.UpdateStyles()

This needs to be in the class you are painting ON, which can be different
then the object where the paint handler is. I normally handle the Paint
event in the same class that I am painting on.

Hope this helps
Jay
