Hi... I have an issue with a graphical control I am writing.
The control has a couple of backgrounds shapes and a waveform display, calculated by going through a byte array, on top of those.
On top of those three are a couple of cursors which I need to update regularly.
My question is,
1. How to I redraw the cursors without having to Invalidate everything in that area?
2. If this is not possible, what would the most efficient way of redrawing the waveform. For example, is it possible to draw into a temporary bitmap?
Cheers
Paul
