ansupa

如何修改下面代码，想要在最后一列 加上工作簿名字及工作表的名字  这样便于区分

Sub Macro1()
Dim MyPath$, MyName$, sh As Worksheet, sht As Worksheet, m&
Set sh = ActiveSheet
MyPath = ThisWorkbook.Path & "\"
MyName = Dir(MyPath & "*.xls")
Application.ScreenUpdating = False
Cells.ClearContents
Do While MyName <> ""
If MyName <> ThisWorkbook.Name Then
With GetObject(MyPath & MyName)
For Each sht In .Sheets
If IsSheetEmpty = IsEmpty(sht.UsedRange) Then
m = m + 1
If m = 1 Then
sht.[a1].CurrentRegion.Copy sh.[a1]
Else
sht.[a4].CurrentRegion.Offset(4).Copy sh.[a65536].End(xlUp).Offset(1)
End If
End If
Next
.Close False
End With
End If
MyName = Dir
Loop
Application.ScreenUpdating = True
End Sub
