How to get parameters of a graphic object drawn using the CWIMAQViewer toolbar?

[aoslo]

I use CWIMAQViewer on a WindowsForm (VB.NET) to display images from a CCD camera.  I then draw a circle using the toolbar to enclose certain features in the image.  I noticed that when I click on the circle and hold the mouse down, the Viewer displays the parameters of the circle (see figure below).  How can I access these parameters in my code?  What is the circle drawn with the toolbar? A region?  An overlay? Thanks.

Figured it out.

The circle drawn is a region, and can be accessed by CWIMAQViewer1.Regions.Item(1).  Thanks.
