A combo box is a control that combines a list box with an edit control. Selecting an item in the list box displays the selected text in the edit control. If the combo box style allows keyboard input, typing characters into the edit control highlights the first list box item that matches the characters typed. A combo box can appear either in a dialog box or on the command bar.

To create a command bar combo box and insert it into a command bar, use the CommandBar_InsertComboBox function.
Note If you provide Style, Font, and Font Size combo boxes, you must position them in the order they are listed in this note.
