 On Error GoTo Err_Work_Days

 End If

 Loop 
 
 Work_Days = WholeWeeks * 5 + EndDays 
 
Exit Function 
 
 Err_Work_Days: 
 
’如果BegDate或EndDate为Null，返回零
，表示这两个日期之间没有工作日。
 
 If Err.Number = 94 Then 
 Work_Days = 0 
 Exit Function 
 Else 
’如果发生其他错误，则提供一条消息。
 MsgBox "Error " & Err.Number & ": " & Err.Description 
 End If 
 
End Function
