Draw on dektop

[tuanhawaii]

Hi all,
I'm quite new to the graphic side of vb.net, and I just wonder if you can draw on the dektop screen programmatically in a window application.
Thanks for any help.

There are a few methods in the System.Windows.Forms.ControlPaint class that will allow you to draw on the screen but are quite limited.
The method I use is to create a form with no border that is the same size as the screen. Setting the form's BackColor and TransparencyKey properties to the same color will give you an invisible form on which you can draw using GDI+ methods.
