学员问题: 如何计算两个时间间隔并转换成“N天N小时N分N秒”这样的形式？  

这里用函数解决

Function timeDiff(dteStart As Date, dteEnd As Date) As String
    Dim lngDiff As Long
    Dim strCheck(3)
    lngDiff = DateDiff("s", dteStart, dteEnd)
    strCheck(0) = CStr(lngDiff Mod 60) & "秒"
    strCheck(1) = CStr(lngDiff \ 60 Mod 60) & "分"
    strCheck(2) = CStr(lngDiff \ 60 \ 60 Mod 24) & "小时"
    strCheck(3) = CStr(lngDiff \ 60 \ 60 \ 24) & "天"
    
    Dim i As Integer
    For i = 0 To 3
        If Left(strCheck(i), 1) = "0" Then
            strCheck(i) = ""
        End If
    Next
    
    timeDiff = strCheck(3) & strCheck(2) & strCheck(1) & strCheck(0)
End Function

Sub test1()
    Debug.Print timeDiff(#6/18/2004 1:01:51 AM#, #6/28/2004 1:01:52 AM#)
End Sub
