I'm new to vb.net, although experienced in other languages. But the first thing I went looking for, I couldn't find! Does vb.net not support rasterops for drawing lines, etc? I want to be able to rubber-band over existing graphics by simply drawing an xor line. Do I have to go to 'unmanaged code' (I'm still coming to grips with that) and do it externally? Or has someone already written a library to do it? Or...?
