佩服!!

复制下来了

我也做了一个时钟，界面是用shape画了一个圆，再画上时针、分针和秒针线。可是出了一个问题，显示时间和系统时间不一致，不知道怎么改？请griefforyou帮我看看。 程序如下： Option Explicit Const PI = 3.14159 Private len_S As Single, len_M As Single, len_H As Single

Private Sub Form_Load() len_S = Sqr((LineS.Y2 - LineS.Y1) ^ 2 + (LineS.X2 - LineS.X1) ^ 2) len_M = Sqr((LineM.Y2 - LineM.Y1) ^ 2 + (LineM.X2 - LineM.X1) ^ 2) len_H = Sqr((LineH.Y2 - LineH.Y1) ^ 2 + (LineH.X2 - LineH.X1) ^ 2) Call Timer1_Timer End Sub

Private Sub Timer1_Timer() Dim s As Single, m As Single, h As Single Form1.Caption = Time s = Second(Time) m = Minute(Time) h = Hour(Time) + m / 60 LineS.X2 = LineS.X1 + len_S * Cos(PI * s / 30) LineS.Y2 = LineS.Y1 + len_S * Sin(PI * s / 30) LineM.X2 = LineM.X1 + len_M * Cos(PI * m / 30) LineM.Y2 = LineM.Y1 + len_M * Sin(PI * m / 30) If h >= 12 Then h = h - 12 LineH.X2 = LineH.X1 + len_H * Cos(PI * h / 6) LineH.Y2 = LineH.Y1 + len_H * Sin(PI * h / 6) End Sub

griefforyou，你是天津红桥区的吗？我是天津河东区的。

把加减号弄反了，Sin Cos也弄反了。。。 我也是河东。 Option Explicit Const PI = 3.14159 Private len_S As Single, len_M As Single, len_H As Single

Private Sub Form_Load() len_S = Sqr((LineS.y2 - LineS.y1) ^ 2 + (LineS.x2 - LineS.x1) ^ 2) len_M = Sqr((LineM.y2 - LineM.y1) ^ 2 + (LineM.x2 - LineM.x1) ^ 2) len_H = Sqr((LineH.y2 - LineH.y1) ^ 2 + (LineH.x2 - LineH.x1) ^ 2) Call Timer1_Timer End Sub

Private Sub Timer1_Timer() Dim s As Single, m As Single, h As Single Form1.Caption = Time s = Second(Time) m = Minute(Time) h = Hour(Time) + m / 60 LineS.x2 = LineS.x1 + len_S * Sin(PI * s / 30) LineS.y2 = LineS.y1 - len_S * Cos(PI * s / 30) LineM.x2 = LineM.x1 + len_M * Sin(PI * m / 30) LineM.y2 = LineM.y1 - len_M * Cos(PI * m / 30) If h >= 12 Then h = h - 12 LineH.x2 = LineH.x1 + len_H * Sin(PI * h / 6) LineH.y2 = LineH.y1 - len_H * Cos(PI * h / 6) End Sub

我复制了下来 但看不了时 分 秒针  为什么啊？

指针是画出来的!!
我是红桥区的!!有QQ吗联系呀!!!

你添加了一个Timer控件并设置Interval属性为500吗？
