So I am creating a painting program, which uses the system drawing pen tool. How can I make an erasure tool, though?
Its in VB.NET
Or how can I make an undo feature? So it undo's the latest drawing. Thanks in advance

I would think that an erase operation would be identical to a draw operation but just using the color of the canvas. – Chris Dunaway Apr 11 '14 at 13:07

@ChrisDunaway Yes, that would be the best way. Though my canvas is not one single color.. – user3523090 Apr 11 '14 at 13:45

For each type of drawing item make a class that holds the properties required for it; color, x, y, etc... Then when they are drawn store them in a collection. Then the Undo feature removes the last element. When drawing you just need to iterate the collection.
Like @Chris Dunaway stated, the erase feature is a pen of the same color as the canvas.
