Question

用vb设计一个简单的计时器代码怎么写？

Answer 1

'添加一个Timer1，一个Command1，一个Label1
Dim H As Integer, M As Integer, S As Integer
Private Sub Command1_Click()
Timer1.Interval = 0
MsgBox H & " 小时 " & M & " 分钟 " & S & " 秒 "
End Sub

Private Sub Form_Load()
Timer1.Interval = 1000
S = 0
M = 0
H = 0
Label1.Caption = Format(H, "00") & ":" & Format(M, "00") & ":" & Format(S, "00")

End Sub

Private Sub Timer1_Timer()
S = S + 1
If S > 60 Then
M = M + 1
End If
If M > 60 Then
H = H + 1
End If
Label1.Caption = Format(H, "00") & ":" & Format(M, "00") & ":" & Format(S, "00")
End Sub

Answer 2

需要利用timer控件，打开计时器时把控件里的时间附一个值给a然后计时结束时候再付另一个值给b，最后b-a（转换下）就出来了吧？
