使用 crontab -e command 編輯時需熟悉 ed 語法，但這個語法我想沒幾個人會吧，而且更換 Editor 還要改系統參數，不同版本的語法也不太一樣:
export EDITOR=vi
在網路上找到一個簡單的方法:
crontab -l > crontab.dat
vi crontab.dat
crontab crontab.dat
將 目前 crontab 的內容轉出，在修改完後在加入即可。

2.建立一個巨集輸入下面代碼
'匯入 VBA 巨集的文字檔
Me.VBProject.VBComponents.Import Filename:="X:\XXXX\test.vbs"
'執行匯入巨集程式
Result = Application.Run("巨集名稱", "Arg#1","Arg#2")
'將匯入之巨集移除，不然下次執行時會出現錯誤
Me.VBProject.VBComponents.Remove Me.VBProject.VBComponents.Item(Me.VBProject.VBComponents.Count)
'顯示傳回結果
MsgBox Result
