List boxes and combo boxes have most of the same properties and operate in a similar fashion. The size of a list box or combo box is determined at design time. If all of the items will not fit into the box, VB automatically adds scroll bars. A combo box control has a Style property, which determines whether or not the list box also has a text box for user entry and whether or not the list will drop down. The dropdown list does not have a text box.
List property holds all elements of the list.
The individual elements can be referenced by using an index . The Clear method may be used to remove all the contents of a listbox. Text 'add item from the textbox of this combobox cboCoffee. RemoveItem 3 'remove the fourth item cboCoffee. ListIndex 'remove selected item cboCoffee.
