ActiveX Control Member: 'Member not found.' Error

Hello Forum,

I'm getting a "Member not found." error for a particular property of an
ActiveX control.

The ExternalStructure reveals that the property is, indeed, there, and
the control instantiates correctly in every other way.

Here's the code:

XtremeCommandBarsPresenter>>#loadMenuBar: anXtremeMenuBar

        | thisBar |
        thisBar := commandBars addMenuBar: anXtremeMenuBar name.
        thisBar doubleGripper: anXtremeMenuBar
keepsImageAndCheckMarkSeparate.
        ^anXtremeMenuBar

where "commandBars" is an instance variable defined in #onViewAvailable
in the following manner:

        commandBars := self view controlDispatch activeMenuBar
commandBars

and XtremeMenuBar>>#keepsImageAndCheckMarkSeparate answers a Boolean
(XtremeMenuBar is my high-level model of this CommandBar).

I have confirmed that the instance variable
"imageAndCheckMarkSeaparated" in XtremeMenuBar is initializing properly
to a Boolean.

Any ideas?

Thank you.


Cheers,

Eric

What type is #addMenuBar: defined as returning? If it is returning a generic
IDispatch, then this might explain the error you are seeing. Trying
inserting a #asImplType to down-cast the result to the actual type.

Ah, yes.  Blair warned me about this with respect to this very same
ActiveX control.  I've been on the watch for this "downcasting" issue.
It would seem I was bitten again.

Thank you.

>What type is #addMenuBar: defined as returning?

I have explored your suggestions a little further, and I don't believe
the problem revolves around type.  #addMenuBar: returns a type of
XtremeCommandBarsICommandBar (CommandBar for short), and that is,
indeed, the type I'm seeing in the debugger.  #doubleGripper and
#doubleGripper: are, in fact, defined in XtremeCommandBarsICommandBar.

>Try inserting a #asImplType to down-cast the result to the actual type.

I assume you mean at the point where I assign the #addMenuBar:'s answer
to an instance variable.  I tried both of the following:

        | thisBar |
        thisBar := (commandBars addMenuBar: anXtremeMenuBar name)
asImplType.

...and...

        | thisBar |
        thisBar := (commandBars addMenuBar: anXtremeMenuBar name)
downCast.

Neither has any effect, and the problem persists.

Still stumped.
