vb打开并重新保存EXCEL文件

使用以下代码可实现打开并重新保存EXCEL文件，从而解决从程序导出的EXCEL文件格式不能被ADO访问的问题,据实验,光是处理一个文件的话需要5秒钟左右,但若批量一起处理的话能缩短到1秒/文件左右. 

************下载来的程序源代码*****************************

Dim   xlApp   As   Excel.Application  
  Dim   xlbook   As   Excel.Workbook  
  Dim   xlsheet   As   Excel.Worksheet  
   
  Private   Sub   Command1_Click()  
      Set   xlApp   =   New   Excel.Application  
      xlApp.Visible   =   True   '设为false，不可见  
      Set   xlbook   =   xlApp.Workbooks.Open("c:/temp/模板.xls")  
      Set   xlsheet   =   xlbook.Worksheets(1)  
       
      xlsheet.Range("A1")   =   "ABC"  
      xlbook.Save  
      xlbook.Close  
      xlApp.Quit  
      Set   xlApp   =   Nothing  
  End   Sub  

******************我的程序******************************************

加入了对中间漏掉程序的处理,若连续丢失10个文件，则认为已经处理完毕，结束处理

Dim xlApp     As Excel.Application
Dim xlbook     As Excel.Workbook
Dim xlsheet     As Excel.Worksheet
 
Private Sub Command1_Click()
    On Error GoTo fix_err
    Set xlApp = New Excel.Application
    Dim i As Integer
    Dim fileName As String
    Dim cWrong As Integer   '连续错误次数，cWrong>10则结束循环
    cWrong = 0
   
    For i = 1 To 20000
        fileName = "c:/temp/hq" & i & ".xls"
        If Dir(fileName) <> "" Then     '文件存在
            Set xlbook = xlApp.Workbooks.Open(fileName)
            xlbook.Save
            cWrong = 0
        Else
            cWrong = cWrong + 1
            If (cWrong > 10) Then
                Exit Sub
            End If
        End If
       
        Label1.Caption = i
    Next i
   
    xlbook.Close
    xlApp.Quit
    Set xlApp = Nothing
   
    MsgBox "ok"
fix_err:
    Debug.Print Err.Description + " " + _
                  Err.Source, vbCritical, "Import"
    Err.Clear
End Sub
