I'm a student with some experience on the drawing in Delphi 2005 and VB.NET. My curent project is to make something that would look like Microsoft Paint. My main problem is redrawing, drawing ghost images. For example if I constantly redraw on mousemove events to show the dimensions of new object I wil lose any previous objects drawn on the surface. Can someone give me any kind of help? It does not have to be a solution, just a some kind of global explanation of how could it be done (redrawing a form and not loosing drawn objects). I could also use some hyperlink if someone could direct me.
