自己设计一个计时器代码

Private Sub Command1_Click()

   Timer1. Enabled=True

   Timer1.Interval=100

End Sub

Private Sub Command2_click

   Form1.Cls

   End Sub

Private Sub Command3_()

   Timer1=False

   End Up

Private Sub Form()Mouse Down(Button As Integer,shift As Integer x As single,y As single)

   'Form1.Circle(Int(Rnd*8000).Int(Rnd*8000)).Int(Int(Rnd*800)

   'FillStyle=Int(Rnd*7)

   'FillColor=QB Color(Int(Rnd*15))

   'Timer1.Interval=10

End sub

Private Sub Timer1_Timer()

   Form1.Circle(Int(Rnd*8000),Int(Rnd*8000)),Int9Rnd*800)

   Fillstyle=Int(Rnd*7)

   Ficolor=QBColor(Int(Rnd*15))

   Line(Int(Rnd*8000),Int(Rnd*8000))-(Int(Rnd*8000)+1000,Int(Rnd*8000))

End Sub
