        The native control provides a great variety in the events it sends in

        the programmers using it). For the reference, here are the cases when
        the final selection is accepted (things are quite interesting when it
        is cancelled too):

        A. Selecting with just the arrows without opening the dropdown:
            1. CBN_SELENDOK
            2. CBN_SELCHANGE

        B. Opening dropdown with F4 and selecting with arrows:
            1. CBN_DROPDOWN
            2. many CBN_SELCHANGE while changing selection in the list
            3. CBN_SELENDOK
            4. CBN_CLOSEUP

        C. Selecting with the mouse:
            1. CBN_DROPDOWN
            -- no intermediate CBN_SELCHANGEs --
            2. CBN_SELENDOK
            3. CBN_CLOSEUP
            4. CBN_SELCHANGE

        Admire the different order of messages in all of those cases, it must
        surely have taken a lot of effort to Microsoft developers to achieve
        such originality.
