ActiveX Controls and Smart Tags

[Michael Keilhack]

Hello,

i have the problem to be compatible with visio 2002.
I need some interaction if some one clicked on a Shape he should see a
button which he can click on.
I see that the best opportunity are Smart Tags but they are only
available in Visio 2003.
Here are my two question:

Can i use Smart Tags (emulating them) also in Visio 2002?

If not how can i dynamicaly add Buttons to the Drawing? (i think ActiveX
Controls are the right think to use)

I use VB.Net for my solution. And the functionality has to be in my
ComAddin.

Thanks for the answers
