Заметки

Create a CComboBoxEx object in two steps:

Call CComboBoxEx to construct a CComboBoxEx object.
Call this member function, which creates the extended Windows combo box and attaches it to the CComboBoxEx object.

When you call Create, MFC initializes the common controls.

When you create the combo box, you can specify any or all of the following combo-box styles:

CBS_SIMPLE
CBS_DROPDOWN
CBS_DROPDOWNLIST
CBS_AUTOHSCROLL
WS_CHILD

All other styles passed when you create the window are ignored. The ComboBoxEx control also supports extended styles that provide additional features. These styles are described in ComboBoxEx control extended styles, in the Windows SDK. Set these styles by calling SetExtendedStyle.

If you want to use extended windows styles with your control, call CreateEx instead of Create.
