VB写Excel的一个问题 - 编程论坛

毕业好多年了最近接手一个VB的东西，功能是用VB把数据做成Excel报表，但是Excel要是只读的，我网上找了段测试代码如下
Private Sub Command1_Click()
On Error GoTo err_handle
  Dim xlApp As Excel.Application
  Dim xlBook As Excel.Workbook
  Dim xlsheet As Excel.Worksheet
  Set xlApp = CreateObject("Excel.Application")
  Set xlBook = xlApp.Workbooks.Add
  xlApp.Visible = False
  Set xlsheet = xlBook.Worksheets("Sheet1")
  xlApp.ScreenUpdating = False
  With xlsheet
  .Range("A1").Value = "A"
  .Range("B1").Value = "B"
  .Range("C1").Value = "C"
  .Range("D1").Value = "D"
  .Range("E1").Value = "E"
  .Range("F1").Value = "F"
  .Range("G1").Value = "G"
  .Range("H1").Value = "H"
  .Range("I1").Value = "I"
  End With
  'xlsheet.Range("A2").CopyFromRecordset Adodc2.Recordset
  xlsheet.Cells.HorizontalAlignment = xlCenter
  xlsheet.Cells.Font.Size = 12

xlsheet.Columns(1).ColumnWidth = 10
xlsheet.Columns(2).ColumnWidth = 10
xlsheet.Columns(3).ColumnWidth = 10
xlsheet.Columns(4).ColumnWidth = 16
xlsheet.Columns(5).ColumnWidth = 10
xlsheet.Columns(6).ColumnWidth = 16
xlsheet.Columns(7).ColumnWidth = 16
xlsheet.Columns(8).ColumnWidth = 10
xlsheet.Columns(9).ColumnWidth = 10

If Dir(App.Path & "\Excel", vbDirectory) = "" Then MkDir App.Path & "\Excel"
xlBook.SaveAs App.Path & "\Excel\Excel.xls"

xlBook.ChangeFileAccess Mode:=Excel.XlFileAccess.xlReadOnly

xlBook.Close
Set xlsheet = Nothing
Set xlBook = Nothing
xlApp.Quit
Set xlApp = Nothing
MsgBox "SUCCESS", , MsgTitle
err_handle:
End Sub
但是excel仍然是可写的，不是只读的，网上搜了半天也找不到办法，不知道有没有高人指点下
