Dim theday As Date

Private Sub Form_Load()
theday = #1/1/2004#
Timer1.Interval = 1000
Timer1.Enabled = True
End Sub
Private Sub Timer1_Timer()
Text1.Text = "离元旦还有 " & Format(theday - Now, "d天h小时m分s秒")
End Sub

各位好像都理解错了啊
上边的都是指定时间的倒计时,

要求是从系统读取当前日期,然后和指定日期来比,这样倒数

比如从现在开始到元旦.其中元旦这个日期是我们指定的

关键是怎样比较两次时间之间的间隔?并且按照一定格式输出
我想应该简单,但是本人很菜,希望高手指教

Dim PASSTIME As Long
Private Sub Form_Load()
Text1.Text = TimeSerial(5, 0, 0)
Timer1.Interval = 1000
Timer1.Enabled = True
PASSTIME = 0
End Sub
Private Sub Timer1_Timer()
PASSTIME = PASSTIME - 1
Text1.Text = TimeSerial(5, 0, PASSTIME)
End Sub

Dim st
Private Sub Form_Load()
Me.Text1.Text = "02:00:00"
st = Time
Me.Timer1.Enabled = True
End Sub
Private Sub Timer1_Timer()
Me.Text1.Text = TimeValue("02:00:00") - (Time - st)
End Sub
注：如果采用Timer1每运行一次减1秒的办法，由于Timer1的运行问题，会使误差分积时累，到最后误差会很大，用每次与系统时间比较算出时差会好一点。

一个timer控件，一个textbox：
Option Explicit
Dim j As Date
Private Sub Form_Load()
j = #2:00:00 AM#
Me.Timer1.Interval = 1000
Text1.Text = CStr(j)
Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
j = DateAdd("s", -1, j)
Text1.Text = CStr(j)
End Sub
