CDialogBar & ToolTips

Environment: VC++ 4.2, Win 95

Problem:
I'm trying to get tool tips using a CDialogBar derived class using a dialog 
with only static text controls. My OnToolTipNotify handler in this derived 
class never gets called.

What I've done:
1. 	Override Create() and or'd CBRS_FLYBY | CBRS_TOOLTIP to the create flags.
2. 	Called EnableToolTips( TRUE );
3. 	Added ON_NOTIFY_EX_RANGE( TTN_NEEDTEXT, 0, 0xFFFF, OnToolTipNotify )
4. 	EnableDocking() for the object and docked the CDialogBar using 
DockControlBar().
5. 	Override int CDockView::OnToolHitTest( CPoint point, TOOLINFO* pTI ) 
const. I called the CDialogBar::OnToolHitTest() and checked to see if hit 
testing was working and my controls were being identified. They were.
6. 	In OnToolHitTest() I checked to see if LPSTR_TEXTCALLBACK was set in the 
TOOLINFO* struct and if hwnd member was the handle to my derived class. They 
were.
7. 	Also in OnToolHitTest() check to see if TTF_SUBCLASS was set in the flags 
for TOOLINFO*. It was not.

Questions:
1.	Since TTF_SUBCLASS  was not set, the docs indicate I need to send 
TTM_RELAYEVENT?  If so, where should I do this in the code?
2. 	Am I off course? Any other ways to get my OnToolTipNotify to be called?

Thanks,
Jeff Smith

Jeremy, this may not be what you want, but if you just want to add
fairly standard static text tooltips to a dialog bar, you can:
1) Choose unique ID's for the controls in the dialog bar.
2) Have string table entries for these ID's in your resource file, just
as you would for a toolbar (ie \n seperating status bar from tooltip
text)
3) Create the dialogbar with CBRS_FLYBY and CBRS_TOOLTIP - don't use
EnableToolTips(TRUE)

Mark.
