需要控件三个:标签label1、计时器timer1、水平滚动条hscroll1。全部代码如下:
Dim Bujinliang As Single
Private Sub Form_Load()
s = "我在滚动……"
Label1 = s
Me.FontSize = 24
Label1.FontSize = 24
Label1.Width = TextWidth(s)
Label1.Height = TextHeight(s)
HScroll1.Max = 1000
HScroll1.Min = 100
HScroll1.LargeChange = 100
HScroll1.SmallChange = 100
Timer1.Interval = 100
End Sub
Private Sub HScroll1_Change()
Bujinliang = HScroll1.Value
End Sub
Private Sub Timer1_Timer()
Label1.Left = Label1.Left - Bujinliang
If Label1.Left < -Label1.Width Then Label1.Left = Width
End Sub
Dim Bujinliang As Single
Private Sub Form_Load()
s = "我在滚动……"
Label1 = s
Me.FontSize = 24
Label1.FontSize = 24
Label1.Width = TextWidth(s)
Label1.Height = TextHeight(s)
HScroll1.Max = 1000
HScroll1.Min = 100
HScroll1.LargeChange = 100
HScroll1.SmallChange = 100
Timer1.Interval = 100
End Sub
Private Sub HScroll1_Change()
Bujinliang = HScroll1.Value
End Sub
Private Sub Timer1_Timer()
Label1.Left = Label1.Left - Bujinliang
If Label1.Left < -Label1.Width Then Label1.Left = Width
End Sub
