Removing items from a ComboBox
You can remove all items or one particular item from the list box part of the ComboxBox. Code
to remove a particular item by it’s Indexnumber looks like this:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e
As_
System.EventArgs) Handles Button1.Click
ComboBox1.Items.RemoveAt(4)
’removing an item by specifying it’s index
End Sub

Code to remove all items from the ComboBox

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e
As_
System.EventArgs) Handles Button1.ClickComboBox1.Items.Clear()
’using the clear method to clear the list box
End Sub

3.4.8 Frame Control
The Visual Basic 6.0 Frame control is replaced by two controls in Visual Basic 2005: the Group
Box control and the Panel control.

2005, the Frame control is replaced by either the GroupBox control or the Panel control.
The GroupBox control is the equivalent of a Frame control with a BorderStyle property of 1
