Hi,

I want to write a control similar to the splitter control,
whereas when the user drags the control a line is drawn
which is then removed depending where the user has the
mouse. (rubber banding?)

Any help much appreciated?

John,
The easiest way to draw an "erasable line" is to use
ControlPaint.DrawReversibleLine.

Using DrawReversibleLine once displays the line, using it a second time with
the same points causes the line to disappear.

ControlPaint is in the System.Windows.Forms namespace.

Note: The points you pass to DrawReversibleLine are in screen coordinates,
not client coordinates.

There is also a ControlPaint.DrawReversibleFrame if you want to draw a box
instead of a straight line.

Hope this helps
Jay

Then just draw a line on mouse down and move and remove it on mouse up
