Mouse event on Picturebox

F

Flair

Hi, all
I've read through those related threads of the keywords: "mouse" &
"picturebox", and it seems that the suggestion to those "tracing mouse event
to draw a dot or lines" problems is "DO NOT ever try to draw on a
picturebox"
So, I would appreciate your replies of the way to do these things below:
1. Show bitmap files. (e.g. a .bmp file under specified path)
2. Make some modifications on the bitmap (such as draw a line by using
stylus) and save it.
My problem is that I can use picturebox to show the bitmap but can't acheive
the second point.
Thanks.

Have you read all the stuff about the GDI to help with bitmap manipulations,
and read about bitblt as well!
