ADO DataGrid 与Excel数据连接

[初学者小李]

如题，请问各位大大，ADO DataGrid Excel可以支持实时的动态数据显示吗？
意思是通过ADO和与Excel连接 通过DataGrid显示在VB界面上，Excel数据是动态变化的~

Dim sSql As String, conn As New ADODB.Connection, rs As New ADODB.Recordset
conn.CursorLocation = adUseClient
conn.Open "provider=microsoft.jet.oledb.4.0;extended properties=excel 8.0;data source=" & ThisWorkbook.Path & "/abc.xls"
Sql = "select * from [sheet1$]"
rs.CursorLocation = adUseClient
rs.Open Sql, conn
DGrid1.ClearFields
Set DGrid1.DataSource = rs
DGrid1.Refresh

数据可以连接，也可显示，就是到第二次跟新数据时出现上图，说无法访问文件！往Excel里写好数据后也关闭了应用程序的！代码如下，请大大帮我看下

Public Sub main()
    Dim i As Long
    ReportName = Year(Date) & "-Report.xls"         'Excel报表文件命名
    DbName = Year(Date) & "-DataBasic.xls"         'Excel数据文件命名
    fn = App.Path & "\" & ReportName
    Dim xlapp As Excel.Application
    Dim xlbook As Excel.Workbook
    Dim xlSheet As Excel.Worksheet
    '创建报表
    If Dir(App.Path & "\" & ReportName) = "" Then         '查询文件是否存在
        Set xlapp = New Excel.Application             '声明对象变量
        xlapp.Visible = True                          '可见
        xlapp.SheetsInNewWorkbook = 1                 '工作薄数量为1个
        Set xlbook = xlapp.Workbooks.Add              '增加工作薄
        xlbook.Sheets("sheet1").Name = "Report"       'Sheet1改名Report
        xlbook.Sheets.Add after:=xlbook.Sheets(1)     '增加工作表在第一个Sheet之后
        xlbook.Sheets("sheet2").Name = "Result"       'Sheet2改名
        Set xlSheet = xlbook.Worksheets("Report")     '声明Report工作表
