Passing A Control Array

Working with control arrays in VB3 was frustrating, but with VB4 you can pass a control array as an argument to a function. Simply specify the parameter type as Variant:
 Private Sub Command1_Click(Index As Integer)
	GetControls Command1()
End Sub

Public Sub GetControls(CArray As Variant)
	Dim C As Control
	For Each C In CArray
		MsgBox C.Index
	Next
End Sub
Also, VB4's control arrays have LBound, Ubound, and Count properties:
 If Command1.Count < Command1.Ubound - _
	Command1.Lbound + 1 Then _
	Msgbox "Array not contiguous"
