No, MessageClass only applies to Outlook forms and more specifically in this
case custom Outlook forms.

I don't see how you could be getting a second Item_Open if you aren't
opening an Outlook item but are opening a custom Windows form. When the
Outlook item opens you should be populating your Windows form with the
details from the Outlook item and then cancelling the opening of the Outlook
form. That shouldn't open another Outlook item.
