4、運(yùn)行VB程序，點(diǎn)擊EXCEL按鈕可以打開EXCEL系統(tǒng)，打開EXCEL系統(tǒng)后，VB程序和EXCEL分別屬兩個(gè)不同的應(yīng)用系統(tǒng)，均可同時(shí)進(jìn)行操作，由于系統(tǒng)加了判斷，因此在VB程序中重復(fù)點(diǎn)擊EXCEL按鈕時(shí)會(huì)提示EXCEL已打開。如果在EXCEL中關(guān)閉EXCEL后再點(diǎn)EXCEL按鈕，則會(huì)重新打開EXCEL。而無論EXCEL打開與否，通過VB程序均可關(guān)閉EXCEL。這樣就實(shí)現(xiàn)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)
