OnDraw
Brian Burgess
Is there any great secret to getting 'OnDraw' to be called in a
Composite Control?
thanks in advance...

to make sure CHAIN_MSG_MAP(baseClass) entry is somewhere at the bottom
of your message map. IIRC ATL Wizard puts the correct entry there.

map..
My OnDraw looks like this:
HRESULT OnDraw(ATL_DRAWINFO& di);
Any other ideas?
thanks

other message entries that come after it. Essentially, CHAIN_MSG_MAP
says that you are done with all the messages you are interested in and
want the rest to be handled by your base class. This is probably not the
cause of your problem though.
Do you, by any chance, have an entry for WM_PAINT in the message map?
OnDraw is called (among other places) from WM_PAINT handler in
CComControl class. If you intercept the message before it gets to
CHAIN_MSG_MAP, you won't get OnDraw.
Show the complete declaration of your class.

Ya I had moved the CHAIN_MSG_MAP, but still nothing...
I dont have a WM_PAINT handler, but I do have WM_CREATE and
WM_INITDIALOG handlers before the CHAIN_MSG_MAP...
at any rate, here is the complete class declaration:

class, CComControl. It is CComControl that has WM_PAINT entry and calls
OnDraw from its handler. The workaround is as follows:
typedef CComControl<CMyCtl, CAxDialogImpl<CMyCtl> > comControlBase;
BEGIN_MSG_MAP(CMyCtl)
// Add your regular message handlers here
CHAIN_MSG_MAP(CComCompositeControl<CMyCtl>)
CHAIN_MSG_MAP(comControlBase)
END_MSG_MAP()
