Change the Active Page in visio

Hi!
 i'm trying to change between visio pages from code. That means i need to set the VisioApplication.ActivePage, but it is readonly. So i'm trying to set the VisioApplication.ActiveWindow.Page.
All good, but when i try that, i get a runtime exception 'Invalid container identifier.'. Anything i tried didn't work. I know that VisioApplication.ActiveWindow.Page is a dynamic variable in c#. But i still don't know how to handle this exception. My code is :

Globals.ThisAddIn.Application.ActiveWindow.Page = Globals.ThisAddIn.Application.ActiveDocument.Pages[0];

I need to mention that it is a Visio AddIn project.
Please, i'm trying to fix this out for 2 weeks, and nothing worked. Any help will be really apreciated.
Thanks!

This may looks stupid, but i found the answer, and i'm writting it for anyone to see this:
Globals.ThisAddIn.Application.ActiveWindow.Page = Globals.ThisAddIn.Application.ActiveDocument.Pages.ItemFromID[MyPageID];

Your line of code above will work, as you've discovered, but it isn't the only way.

ActiveWindow.Page is the correct object and you change active pages from code by equating it to a page name or page reference. For example, assuming that "Page-1" is the first page in the document, all three of these will switch to that page:

    ActiveWindow.Page = "Page-1"
   
    ActiveWindow.Page = ActiveDocument.Pages(1)

    ActiveWindow.Page = ActiveDocument.Pages("Page-1")

BTW, refer to the very first sample on this page of VBA code samples for Visio.
