Hello. I have an image in a picture box. I want to highlight an area and zoom in. I have all the code and I can zoom in properly. My MouseDown() and MouseUp() seems to be working fine.

I want to draw a white rectangle outline to show the area im selecting to zoom. I know Java had a MouseDragged() i was wondering if C# has anything like that as i can not seem to find it. MouseMove doesnt seem to work how I want it.

If anyone could help me, I would be vey gratefull.Even an example of something doing a similar thing?
Thanks Andy.
