Hi Eva, I first want to say that I do not have an answer for your question, sorry about that. In reading your question you an ahead of me in implementing IContentsView in ArcGis 10. I do have a question though, I am coverting over to ArcGis 10 and I have not figured out how IContentsView is implemented. In 9.3 ContentsView was registered in ArcGISCategoryRegistration (I am working on add-ins in ArcGis 10, no Com stuff), now, what kicks off, fires off, starts, recognizes the contentsview when the application is started so that I have access to the table of contents.
Thank you for your time, Dale,
