I see what your are saying SuperMario, and this may have been one of the problems I was having.  Since adding the controls programatically however, the problem has gone away.  I guess this means I should stick to doing things in code rather than the xcb.

To all who have responded to this thread, please accept my thanks.  Your replies made it a LOT easier to identify the problems I was having!

OK.  I think we're getting closer here...

Changed all of the frame controls to PictureBox controls.  Reran code, same problem.

Deleted all of the CommandBar controls by editing the VB form using Notepad.  Opened up the form in the IDE, added the controls back in, BUT I commented out the following (and it works!):

CommandBars1.LoadDesignerBars App.Path & "\BasicNavigation.xcb"
CommandBars2.LoadDesignerBars App.Path & "\BasicNavigation.xcb"

For i = 0 To 4
    CommandBars3(i).LoadDesignerBars App.Path & "\MinorNavigation.xcb"
    CommandBars3(i)(2).ContextMenuPresen t = False

Next
CommandBars4.LoadDesignerBars App.Path & "\MinorNavigation.xcb"
CommandBars4(1).ContextMenuPresent = False

As long as I don't load the designer bars, I am able to save, close, and reopen the app without a problem.  This is not a big issue because I am in the process of using code to design the CBs, so this language will be deleted anyway.  But I think the problem has been either (1) you can't load the same designer info to more than one CB at the same time, or (2) I'm doing something wrong with the ContextMenuPresent property.

Am I heading in the right direction?

Hold on.  I just noticed that at least one of the controls hosting a CommandBar control is in fact a Frame control.  Sounds like this is a big no no, so I'm going to change this and see if that fixes the problem.  Will report results.

Thanks!

That's what I've been doing.  Actually, I've set this up so that each codejock tab points to a PictureBox control as the OLE_HANDLE, then inserted a PictureBox control within THAT PictureBox control, then inserted a CommandBar control within THAT PictureBox control.  Make sense?

Also, I am assuming there is no way to use one CommandBar control and programatically create each CommandBarControl and "assign" them to a PictureBox control, correct?  

That's the problem.  I have created 6 different CommandBar objects for the form, and placed each of those CommandBar objects in separate PictureBox controls.  You're saying this should work?  Then why is the form crashing every time I try and start it?

Is there any thread out there, or other codejock documentation, that covers this in any detail?  I was going to try creating 6 additional borderless forms today, dropping the CommandBar control on each new form, and pointing the OLE_HANDLE of the tabs to these new forms to see if that would work.  That seems like a rather inefficient way to have to do it though...

Thanks for the responses! I gotta say the codejock forum has been great for response times.

you can't. you must create 6 CommandBars objects for each PictureBox and  place them on PictureBox (not Frame)

After a few hit and misses, I was able to load icons fairly easily.  Using an existing resource file to store the image works fine (and also avoids have to reload/duplicate).

I continue to have a problem briefly mentioned earlier:

We have a VB6 form which hosts a fairly complex series of multiple tabs/sub tabs, etc.  I am using the codejock tabcontrol for this purpose.  A few of these different tabs require a control to help the user navigate through some database records.  Because I can't figure out how you would create say, 6 different toolbars from one instance of the CommandBar instance AND have each toolbar show up on a different tab, I have instead tried dropping the CommandBar control in six different picturebox controls to see if I could make that work.

Three times now I have done this and closed the code thinking that it was working.  When I've later gone back to reopen the code however, VB crashes when I merely try and open the form to view it (something about "could not read memory...).  I'm guessing that it doesn't like the fact that I'm using 6 different CommandBar controls on the same form.

Is it possible to do what I wanted to do to begin with, which is add one CommandBar control and programatically create 6 toolbars which will be resident on six different picturebox controls?  This would obviously be the right way to go, and avoid having to even deal with the crashes I'm having doing it the way I am now.  Seems like the CommandBar control would need an "Owner" property (which I don't seem to be able to find), or something like that, for each CommandBarControl object created to associate 6 different picturebox controls??

Thanks!
