Borders Collection [Excel 2003 VBA Language Reference]
Using the Borders Collection
Use the Borders property to return the Borders collection, which contains all four borders. The following example adds a double border to cell A1 on worksheet one.
Worksheets(1).Range("A1").Borders.LineStyle = xlDouble
Use Borders(index), where index identifies the border, to return a single Border object. The following example sets the color of the bottom border of cells A1:G1 to red.
Worksheets("Sheet1").Range("A1:G1"). _ Borders(xlEdgeBottom).Color = RGB(255, 0, 0)
Index can be one of the following XlBordersIndex constants: xlDiagonalDown, xlDiagonalUp, xlEdgeBottom, xlEdgeLeft, xlEdgeRight, or xlEdgeTop, xlInsideHorizontal, or xlInsideVertical.
You can set border properties for an individual border only with Range and Style objects. Other bordered objects, such as check boxes and chart areas, have a border that's treated as a single entity, regardless of how many sides it has. For these objects, you must return and set properties for the entire border as a unit. For more information, see the Border object.
