无聊写了以下程序，有更好的线条画法，请下方留言。窗体拖入控件：Timer1 执行以下代码：
程序代码：Option Explicit '窗体透明，控件不透明 Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long Private Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As Long Const WS_EX_LAYERED = &H80000 Const GWL_EXSTYLE = (-20) Const LWA_COLORKEY = &H1 '窗体置顶 Private Declare Function SetWindowPos& Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) Private Sub Form_Load() Dim i As Long, j As Long If App.PrevInstance = True Then End '如果重复进程，则退出 Form1.AutoRedraw = True Form1.ScaleMode = vbPixels Form1.DrawWidth = 1.45 '窗体全屏 Me.BorderStyle = False Me.Caption = "" Me.Move 0, 0, Screen.Width, Screen.Height '窗体透明 BackColor = &HFEFEFE SetWindowLong hwnd, GWL_EXSTYLE, WS_EX_LAYERED SetLayeredWindowAttributes hwnd, &HFEFEFE, 0, LWA_COLORKEY '这里的 0 表示透明度 '绘制线条 For i = Form1.ScaleWidth / 3 To Form1.ScaleWidth / 3 + 6 Step 2 Form1.Line (Form1.ScaleWidth / 3 + i, 0)-(Form1.ScaleWidth / 3 + i, Form1.Height), Int(16581375 * Rnd + 0) Next For j = Form1.ScaleWidth / 3 + 10 To Form1.ScaleWidth / 3 + 16 Step 2 Form1.Line (Form1.ScaleWidth / 3 + j, 0)-(Form1.ScaleWidth / 3 + j, Form1.Height), Int(16581375 * Rnd + 0) Next Timer1.Interval = 1000 End Sub Private Sub Timer1_Timer() '让窗体在顶层 Dim rtn rtn = SetWindowPos(Me.hwnd, -1, 0, 0, 0, 0, 3) End Sub
