Environment: Windows XP Pro & NI Vision 8.5

Among several regions within a CWIMAQViewer, how can I know which one is being selected?

How are you selecting your ROI's?

I mean that if a user selects one of the regions in the viewer & I want to display the relevant that the parameters for that region. Because I couldn't see any event available to do this.

would it be possible for you to post your code?
