一个非常简单的倒计时程序，使用一个Timer控件，二个Label控件即可，代码如下：

Dim W As Double, TI As Double, SI As Double, FE As Double, MI As Double

Private Sub Form_Load()
Timer1.Enabled = True
Timer1.Interval = 1000
Label1.Caption = ""
Label3.Caption = ""
W = DateDiff("s", Now, "2011-10-1 00:00:00")
End Sub

Private Sub Timer1_Timer()
Dim SI1 As String, FE1 As String, MI1 As String
W = W - 1
TI = Int(W / 24 / 60 / 60)
SI = Int((W - TI * 24 * 60 * 60) / 60 / 60)
FE = Int((W - TI * 24 * 60 * 60 - SI * 60 * 60) / 60)
MI = W - TI * 24 * 60 * 60 - SI * 60 * 60 - FE * 60
Label1.Caption = CStr(TI) & "天"
If SI < 10 Then
SI1 = "0" & CStr(SI)
Else
SI1 = CStr(SI)
End If
If FE < 10 Then
FE1 = "0" & CStr(FE)
Else
FE1 = CStr(FE)
End If
If MI < 10 Then
MI1 = "0" & CStr(MI)
Else
MI1 = CStr(MI)
End If
Label3.Caption = SI1 & "小时" & FE1 & "分" & MI1 & "秒"
End Sub

什么问题 。
要求是什么？

好的
