VB编写的倒计时程序，测试时，请输入目标日期与时间，格式如演示截图中所示，然后按下“倒计时”按钮，即可开始倒计时了，会显示出具体剩余的天数和时、分、秒。程序主要基于CDate函数和DateDiff函数来实现，主要代码如下：
Private Sub Timer1_Timer()
On Error GoTo H
Timer1.Interval = 1000
Dim i As Date
i = CDate(Text1)
Label1.Caption = "距离" & Text1 & "还剩" & DateDiff("d", Now, i) & "天" & CLng(DateDiff("h", Now, i)) Mod 24 & "小时" & CLng(DateDiff("n", Now, i)) Mod 60 & "分" & CLng(DateDiff("s", Now, i)) Mod 60 & " 秒"
Exit Sub
H:
MsgBox "请输入正确的时间"
Timer1.Enabled = False
End Sub
