wasn't too hard, but now I'm wanting to create a program
that will allow me to:

Jagged icons in VB.NET Imagelist? ARGH! Posted by Moogy at 12/29/2003 6:23:33 PM Every time I load a nice-looking Windows XP Icon into my VB.NET Imagelist,
it turns out ugly and jagged around the edges. I believe this is from the
Alpha pixels being mapped to mask pixels instead of keeping their alpha

The ImageList is 32bbp with a size of 16x16.
So, ...more >>

How do you increase the nonclient area to support a border in a UserControl Posted by Paul at 12/29/2003 4:01:15 PM I am mainly learning and wanted to develop a simple control - like the panel control, but want to make custom borders. Now the easy way is to simply use the controlpaint.drawborder, but this draws in the user area and not the non-client area, thus not giving the same effect as Microsofts panel cont...more >>

What I noticed is that the overlapped part of 2 circles is not filled as it
is not inside the path...
How can I add multiple closed figures as circles to a GP a...more >>
