vba中Range对象的Replace方法

replace是Range对象的一个方法，用于单元格替换.

 

 

 

 

 

 

Sub replaceTest()
    Application.ReplaceFormat.Interior.Color = vbGreen
    '指定lookat参数为Whole，从而避免将21等包含2的数字也替换掉'
    Range("b2:e4").Replace what:=2, replacement:=3, lookat:=xlWhole, ReplaceFormat:=True
    
End Sub

End Sub


Sub FindLastRow()

  Dim r As Range, maxRow As Long, i As Long

    '如果该行号大于之前找到的最大行号，则更新最大行号'
    If r.Row > maxRow Then maxRow = r.Row
  Next i
  
  MsgBox "最后一个数据在第" & maxRow & "行"
    
End Sub

   Dim i As Long
