Refactor CPropertySheet as CXTPDockingPane's?

hi -

I'm refactoring some pretty old code, currently working on porting over a CPropertySheet with a bunch of CPropertyPages and embedding them into our new CJ interface.  The CPropertySheet embeds fine, but the overall look and feel doesn't fit.  So I spent some time today playing around with each separate tab as a docked pane, but I couldn't seem to figure out how to make the panes stay within the docking panel (ie, the user can click and drag them out of the panel and dock them with other unrelated UI components).

How can I prevent the user docking these panes in other panels?  Or, alternatively, is there any simple way of embedding a propertysheet into a panel without the titlebar, external borders and other UI bits and pieces?

thanks.

Have tried removing WS_BORDER in OnCreate() and PreCreateWindow() (not called) for both the property sheet and property page, but the border stays put.

I'm inclined to think that a pane which can't acquire or lose tabs is the best way to go, but I'm having some difficulty in figuring out how to do this.

Thanks -- it's working fine now, with the exception that I can't quite figure out how to permit double-clicking on the docking panel title bar (to dock a full floating panel with 8 tabs), while stopping people double-clicking on the panel tabs and causing individual panels to dock away from the still-floating panel.  The message flows seem almost identical.  Not a major issue anyway.

thanks again for your help!
