Hi

I'm writing a program using visual C++.NET that lets users create boxes, drag them around a link them. I'm new to the gui world and am having lots of syntax errors using .net. So far, i've created a picturebox and everytime the user choses to add a box, a rectangle is drawn. I track the rectangles movements using mouse events and invalidate to re-draw the screen.

The problem is when there are 2 or more boxes on the screen i only want to invalidate the "clean" region. So i thought id create a region comprising of the picturebox and exclude rectangles as they're created.. so when i cal invalidate only the clean area is re-drawn.

But i can't seem to create a region:
Region R = Region(pictureBox):
or even Region R = Region(a); ...where a is a rectangle.

I'd really really appreciate any assistance i can get.
Much thank
Aileen =O)

You need to create a new instance of the Region.


You can't do anything with the first version though, because pictureBox is just a control...or is it? Well, that's what the name suggests, anyway...

Regards,
Luci
