CTreeCtrl in CControlBar = no TVN_ENDLABELEDIT?

I have a control bar in my app in which I have placed a CTreeCtrl. I need
to allow the user to edit the text of a tree item in the standard way,
i.e. clicking on it and waiting for the edit box to appear, similar to
what happens in the tree pane of explorer when renaming a file or
directory. The problem is that when the user presses ENTER or ESC, the
CTreeCtrl doesn't seem to receive it, and I get no TVN_ENDLABELEDIT
notification. Using SPY++, I have determined that there is a WM_COMMAND
message coming through, and sometimes a WM_GETDLGCODE. My guess is that I
am getting some kind of dialog box default button behavior, even though it
isn't a dialog bar. I have played with WM_GETDLGCODE handling to no avail
- though it's very possible I'm doing this incorrectly.

I have searched the archives and MSDN, and re-read "Meandering Through the
Maze of MFC Message and Command Routing" to no avail, but once again I
could simply be using the wrong keywords.

Any information regarding where the WM_CHAR is disappearing to would be
extremely helpful!

Keys get handled by main frame when it does accelerator key tests.
Try overriding PreTranslateMessage (or OnKeyDown) to get these
events and send/post directly to your control

(Have a look at the MFC sample DOCKTOOL which includes
a combo box which overrides PreTranslateMessage -- it's not
a tree control, but is a control in a toolbar)
