Referencing DBGrid's Columns Using Object Variables

In VB4, DBGrid's columns can be referenced using object variables. This reduces the amount of typing required and makes code more readable. The code is also more efficient because the full name doesn't need resolved with each reference. For example:
 Dim Col() As Column
Dim NumCols As Integer

Private Sub Form_Load()
	Data1.RecordSource = "SELECT * FROM Publishers;"
	Data1.Refresh

	NumCols = DBGrid1.Columns.Count
	ReDim Col(NumCols)
	Dim i As Integer

	For i = 0 To NumCols - 1
		Set Col(i) = DBGrid1.Columns(i)
		Col(i).AllowSizing = False 'disable user sizing
		Col(i).DividerStyle = 0 'right divider = none
	Next i
End Sub
