CommandBarComboBox Object (Office)
Represents a combo box control on a command bar.
Use Controls(index), where index is the index number of the control, to return a CommandBarComboBox object. Note that the Type property of the control must be msoControlEdit, msoControlDropdown, msoControlComboBox, msoControlButtonDropdown, msoControlSplitDropdown, msoControlOCXDropdown, msoControlGraphicCombo, or msoControlGraphicDropdown.
The following example adds two items to the second control on the command bar named Custom, and then it adjusts the size of the control.
Set combo = CommandBars("Custom").Controls(2) With combo .AddItem "First Item", 1 .AddItem "Second Item", 2 .DropDownLines = 3 .DropDownWidth = 75 .ListIndex = 0 End With
You can also use the FindControl method to return a CommandBarComboBox object. The following example searches all command bars for a visible CommandBarComboBox object whose tag is "sheet assignments."
Set myControl = CommandBars.FindControl _ (Type:=msoControlComboBox, Tag:="sheet assignments", Visible:=True)
