Hosted vb6 activeX control dialogues not appearing in win forms

Hi,

I have hosted a vb6 activeX control in win forms, the hosted control is showing up some initial data in the tree and we can right click and say Add which then pops up a dialog to get new values, but for hosted control clicking on Add is not showing up the get new values dialog, however there is another menu which says FromFile which opens file dialog box and the hosted control is also opening file dialog box but not the windows developed in vb6.

What should we do in such a case? Please suggest.

Thanks,
Anurodh
