Hi,

The message is clear but what is not clear is the question, are you asking
how to draw it? If so you can use GDI+ functions to draw the lines based on
an array of points.

I have done an application before that when the mouse move was forcing a
repaint with the last point based on the mouse hotspot so you can easily draw
irregular shapes.

GDI+ functions are stored on the System.Drawing namespace.

Hope this helps
