Thanks though. But as soon as I corrected that problem, I became tired of the pictureboxes slow update speeds, so I shrank it to 20 x 20 and quit using it. I started drawing to the form again, but now I

      • I created an icon, then clicked on the form, then went to the form's properties and set the Icon property to point to the icon file. What I want is the icon to show up in the title bar of the form, and show up on the taskbar when the form is minimized. But, this isn't working. I'm puzzled because I thought that was what the Icon property was for. Oh, the form's ShowIcon property is set to true.
