4、運行VB程序，點擊EXCEL按鈕可以打開EXCEL系統，打開EXCEL系統后，VB程序和EXCEL分別屬兩個不同的應用系統，均可同時進行操作，由于系統加了判斷，因此在VB程序中重復點擊EXCEL按鈕時會提示EXCEL已打開。如果在EXCEL中關閉EXCEL后再點EXCEL按鈕，則會重新打開EXCEL。而無論EXCEL打開與否，通過VB程序均可關閉EXCEL。這樣就實現了VB與EXCEL的無縫連接。Public Function OutputToExcel(Optional Rs_Data As adodb.Recordset, Optional Cn As adodb.Connection, Optional strSQL As String)
