Creates a combo box, which initially displays a single item. However, when you select the combo box, it displays a list of items that you can choose an item from.
A combo box combines the features of a text box and a list box. You can enter information in the text box portion or select an item from the list box portion of the control.
To show or hide the list in a combo box,
select the control and press
ALT+DOWN ARROW.
都不看幫助的。ComboBox的Combo前綴,就是combines,即組合、聯合,是兩個更基本控件的組合容器。
