Command1.Caption = "结束"
Timer1.Interval = 1000
End If
Else
Command1.Caption = "开始"
Timer1.Interval = 0
If Text1 <> 0 Then Text1 = Text1 / 60
End If
End Sub
Private Sub Form_Load()
Frame1.Caption = "请输入倒计时的分钟数"
Text1 = ""
Command1.Caption = "开始"
End Sub
Private Sub Timer1_Timer()
If Command1.Caption = "开始" Then Exit Sub
Text1 = Text1 - 1
If Text1 <= 0 Then
