How to work with currently-selected diagrams only?

[panfiluta]

Hi all,

I'd like my add-in to work with the selected diagrams only.
I'm using C#, so I tried something like this:

EA.Package = ...
foreach (EA.Diagram diagram in package.Diagrams)
{    
      if (diagram.SelectedObjects.Count > 0)
      {.....

But when there is no diagram selected I get an error message saying that I cannot do .SelectedObjects.Count on hidden diagrams.

Is there a way to find out whether the diagram is hidden or not?

Thanks a lot.

I think the diagram returned by Repository.GetCurrentDiagram is the only safe diagram to use SelectedObjects on.
