well, in vb6 when you wanted to draw something you could change the draw mode the way you wanted....
Let's say I draw a line on a picturebox, there is no way to ERASE that line unless I save the content of the picturebox before drawing the line. In vb6 I could set the drawmode to vbXorPen (not sure if it was this one) and then I could draw a second line with the exact same coordinates, and that would erase the old line. How could I possibly do this in vb.net?
