This example displays a selected list item in a TextBox control when either a CommandButton control is clicked or a list item is double-clicked. To try this example, paste the code into the Declarations section of a Form object that contains a ListBox control, a TextBox control, and a CommandButton control. Then run the example and click the CommandButton control or double-click an item in the ListBox control.
Private Sub Form_Load ()
List1.AddItem "John" ' Add list box entries.
List1.AddItem "Paul"
List1.AddItem "George"
List1.AddItem "Ringo"
End Sub
Private Sub List1_DblClick ()
Command1.Value = True ' Trigger Click event.
End Sub
Private Sub Command1_Click ()
Text1.Text = List1.Text ' Display selection.
End Sub
