OLE Insertable Object

[Tsun Mok]

This is a long old question I found no
answer for 2 years.
How do I make my custom ActiveX control
shows up in the list of Object Type,
in Insert Object dialog in the VB OLE control.

Thanks

Well, first of all, I'm not sure the ActiveX control specification
allows them to be insertable objects in that manner.
Remember, ActiveX controls must, by definition, run in-process. This may
preclude them from being insertable.
If it is possible, then it would be a matter of setting some of the OLE
styles published by the control. It's been a long
time since I've looked at this, so I'd have to research it further to
figure out which style bits needed to be set. Then,
I'd probably need to extend SpyWorks to override the necessary interface
so that a VB control could set those style bits.

In other words - this is not a trivial endeavor.

Dan,

After I installed a 3rd party ActiveX
Control, they showed up in the Insert Object
list. I took a look at the Window Registry,
they have an attribute set to "Insertable"
I am wondering whether I could do the same
by setting the attribute to "Insertable".
Sounds like it is not as easy as I thought.


Thanks

Give it a try. Whether the control works or not when inserted is another
issue:-)
