ActiveX OnSize and OnMove messages in PowerPoint

[EatenByAGrue]

I have a simple ActiveX project I've added to my solution, generated from the
Visual Studio wizard (ActiveX MFC project). I have added C++ code to my
solution that uses the Office Object Model to add my ActiveX to any
particular slide (using Shapes.AddOLEObject). I need to know whenever my
ActiveX is moved or resized, so I figured it would be easy enough to just
listen for the appropriate events with OnMove or OnSize. Sadly, these never
get called from PowerPoint, with one exception. If I enter Slide Show mode
in PowerPoint, OnMove and OnSize immediately get called. How can I trap
these events in normal editing mode in PowerPoint?

Unfortunately, the problem I have is that I need to modify other Shapes when
this particular Shape is moved or resized. I looked over the PPT events, but
I didn't see anything that looked like what I need. I figured that the
ActiveX object would be part of the Windows event system, but that appears to
only be valid when I'm viewing the slide show, not editing. I guess I could
just capture the WindowActivate, WindowDeactivate, and WindowSelectionChange
and handle my adjustment through them. A shame to have to go through what
seems like a less intuitive route to solve the problem, but if that's all I
have to work with then that's all I can do Thanks for your suggestion!

Hmmm,

Couldn't you set a "mousedown" event on the control and then track the
cursors movement/position? If it changes you know the controls
position/size has been altered.

I tried adding a mouse listener to it, but I am not getting those messages,
either. The only event I've noticed that is actually being reported while
editing in PowerPoint is the paint. I think that it all may have to do with
OLE's difference between edit mode and user mode, but I tried overriding the
calls that set that boolean value and it never gets called, either.

Yep, that's pretty much what I'm doing now Thanks for the suggestions.
As for Austin's suggestion, I tried adding a mouse listener and still got
nothing. Did I misunderstand the concept he was describing?
