Summary:
The owner-draw combo box styles (CBS_OWNERDRAWFIXED and
CBS_OWNERDRAWVARIABLE) are incompatible with the combo box styles that
contain an edit control (combo box styles CBS_SIMPLE and
CBS_DROPDOWN). A combo box with either the CBS_SIMPLE or CBS_DROPDOWN
style displays the currently selected item in its associated edit
control. When an owner-draw style is specified for the combo box style
CBS_SIMPLE or CBS_DROPDOWN, the current selection may not be
displayed. Using the SetWindowText function to display the current
selection in response to a CBN_SELCHANGE message may not be effective.
More Information:
An owner-draw combo box can contain bitmaps or other graphic elements
in its list box. Therefore, to correctly display the current
selection, it is necessary to display a bitmap or other graphic
element in the edit control. Because edit controls are not designed to
display graphics, there is no natural method to display the current
selection in an owner-draw combo box with an edit control.
The combo box style CBS_DROPDOWNLIST, which has a static text area
instead of an edit control, can display any item, including graphics.
Use this style combo box with the owner-draw styles.
