用VB编写倒计时器的时候我设置倒计时为20秒,怎么开始倒计时的时候是1199开始倒计啊? 下面是代码Dim m As LongPrivate Sub Command1_Click()Timer1.Enabled = Truem = Val(Text1.Text) * 60Label1.Caption = "现在开始倒计时"Command1.Visible = FalseEnd SubPrivate Sub Timer1_Timer()m = m - 1If m < 0 ThenTimer1.Enabled = FalseMsgBox "时间到", 0, "倒计时"Label1.Caption = " 请输入倒计时的分钟数"Text1.Text = ""Command1.Visible = TrueElseText1.Text = mEnd IfEnd Sub
