vba loop through cell edges for border

Basically, I want to loop through the edges in the Borders collection. is there any "for each" way to do this?

Private Function getCellBorder(ByVal vArg As Range) As String

  For Each Edge in Borders
    Debug.Print vArg.Borders(Edge).LineStyle
  开发者_Python百科Next Edge

End Function

Function getCellBorder(ByVal vArg As Range) As String

Dim a

  For Each a In vArg.Borders 
     Debug.Print a.LineStyle
  Next a

End Function  

Edit

The following is a much more sofisticated code that uses some kind of reflection and iterates on Enums.

The Enum tyes are catchy in Excel since you can't loop on those ... except with this trick.

Option Explicit
Option Compare Text

Sub a()
getCellBorder (Worksheets("Sheet1").Range("A1"))
End Sub

HTH!

Not really. I suppose you could define an Edge array/type/enum, but since we're only talking about a handful of borders, it's not really worth it (oh, and your psuedo code would also include diagonal borders as well). Here's some of my production code:

With Objws.Application.Selection
    .NumberFormat = "#,##0"
    .Borders(xlEdgeLeft).LineStyle = xlContinuous
    .Borders(xlEdgeRight).LineStyle = xlContinuous
    .Borders(xlEdgeTop).LineStyle = xlContinuous
    .Borders(xlEdgeBottom).LineStyle = xlContinuous
    .Borders(xlInsideVertical).LineStyle = xlContinuous
    .Borders(xlInsideHorizontal).LineStyle = xlContinuous
    .HorizontalAlignment = xlHAlignCenter
    .VerticalAlignment = xlVAlignCenter
    .WrapText = True

Keep in mind there is such a thing as "over-optimizing" your code.
