I wish to display a special dialog when the drop-down button is pressed (not a menu). Is there any way to just get a message?

This is CExtBarButton in the toolbar, not CExtButton

Please create your CExtBarButton-derived class which implements the CExtBarButton::GetSeparatedDropDown(), CExtBarButton::IsAbleToTrackMenu() and CExtBarButton::OnTrackPopup() virtual methods. First two methods should simply return true flag. Last method should display dialog instead of tracking popup menu. The CExtToolControlBar::OnCreateBarCommandBtn() method creates instances of toolbar buttons. You can override it for instantiating your toolbar button objects for particular command identifiers.

I tried capturing the g_nMsgPrepareMenu command and setting m_bMenuCanceled but that results in an exception thrown at line 4219 of ExtToolControlBar.cpp when pPopup is deleted. The hWnd for pPopup is 0xfeeefeee (I’m on 2.83)

Please override the CExtButton::_IsMenuAvail() virtual method and simply return true from it. The override the CExtButton::_OnTrackPopup() virtual method and display dialog in it.
