The ROP (raster operation) modes used in GDI are not present in GDI+. The
ControlPaint method uses GDI interop to provide a limited selection of XOR
objects with the DrawReversible<xxx> methods. The reason for this is that
easy alpha-blending is supposed to be better.
Personally, I would have liked to have seen raster ops too but we have to
live without them.

In VB 6 your could set the drawmode property to 7 (XorPen), which meant if
you drew a line twice it disappeared, is there a way of getting an
equivalent effect in VB.Net
