Hi,

I am trying to figure out how to create an object that users can insert
into Powerpoint and Excel by going to Insert--Object (and I will
hopefully be able to insert one programmatically as well).

The behavior I need from my object is very similar to that of MS Graph.
I want to be able to go to "Insert--Object", and instead of choosing
MSGraph, choose MyObject. Then, I would like to be able to click on the
created instance on the slide/worksheet and be able to format it--the
same way that a user can interact with MSGraph, but of course with
whatever functionality I write.

What is the best way to do this? I am getting a bit confused with
ActiveX controls/exes/dlls and OLE objects and not sure what to use. I
can create a control that can be added from the control toolbox, but not
through Insert--Object. Also, I'm not sure how to go about adding to
it the functionality similar to MSGraph.

I truly appreciate any help you might be able to give me!

Thanks in advance,

-Casey
