Hello,

1) I would like to ask whether it is possible to call a composite control
from another composite control in a web browser. If it is possible, how can
i call it?

I have tried to call a dialog from a composite control and it is successful
but it is not successful to call composite control from another composite
control.

2) The composite control is based on template of dialog. Is anything the
composite control can do but dialog cannot do ? I mean any difference
between them ?

Regards,

David

1) If you are asking how two controls hosted on the same page can
discover each other, do the following. Call IOleClientSite::GetContainer
to obtain IOleContainer interface (you have the site pointer in
CComControl::m_spClientSite member). Use IOleContainer::EnumObjects to
enumerate all controls on a page. Query each for some agreed upon
interface, to figure out which of them is the one you are interested in.

2) I don't understand the question. Do you have problems with anything
in particular?
