Hi everybody,

I have a COM object implemented in a DLL and I want to make its
functionality available to Excel users.

In Excel I would instantiate COM interfaces from the DLL as well as some VBA
classes, which server as callback objects. After calling certain methods in
the COM object, they will start several threads, each of which will need to
call methods in the callback objects. Is this doable in Excel? And for those
who know VB, is it possible in VB at all?

Any help will be greately appreciated,

Thanks,

Adrian
