Hi,
I wrote a simple program using GDI+ that places two rectangles on the screen based on values typed in two textboxes. I did this by creating 24 rectangles 10 pixels apart and drawing the rectangle that coorisponds with the typed int32 when a button is pressed. Now I want all the rectangles in between the two that are drawn to the screen to also be drawn. I tried doing this many ways and googling for info and had no luck. My code is below. Any ideas
