这是一个简单的计时器
Private Sub CommandButton1_Click()
Dim Duration, Start As Long
Duration = TextBox2.Text
Start = Timer
Do While Timer < Start + Duration
DoEvents
TextBox1.Text = Duration – (Timer – Start)
Loop
TextBox1.Text = 0
MsgBox “OK”, vbOKOnly, “Title”
End Sub
下面的是一个辩论用的计时器Dim Selected As LongPrivate Sub CommandButton1_Click() Selected = 1End SubPrivate Sub CommandButton2_Click() Selected = 2End SubPrivate Sub CommandButton3_Click() Dim Duration1, Start1, End1, Duration2, Start2, End2 As Long Duration1 = TextBox1.Text Duration2 = TextBox2.Text Selected = 1 Start = Timer Do While Duration1 + Duration2 >= 0 If Selected = 1 Then Do While Duration1 > 0 Start1 = Timer If Selected = 1 Then DoEvents Duration1 = Duration1 – (Timer – Start1) TextBox1.Text = Duration1 If Duration1 <= 0 Then MsgBox “正方时间到”, vbOKOnly, “Title” Selected = 2 Exit Do End If Else Exit Do End If Loop ElseIf Selected = 2 Then Do While Duration2 > 0 Start2 = Timer If Selected = 2 Then DoEvents Duration2 = Duration2 – (Timer – Start2) TextBox2.Text = Duration2 If Duration2 <= 0 Then MsgBox “反方时间到”, vbOKOnly, “Title” Selected = 1 Exit Do End If Else Exit Do End If Loop End If Loop TextBox1.Text = 0 MsgBox “OK”, vbOKOnly, “Title”End Sub
只有经历过地狱般的折磨，才有征服天堂的力量，只有流过血的手指，才能弹出世间的绝唱。
