VB.NET 点击和点击同时点击表格

Question

使用下面的代码，我可以点击，但我必须同时点击表单，因为我想要一个透明的表单点击后面，但每次点击时我都必须放一首歌曲。

这是代码，

Imports System.Runtime.InteropServices

Public Class GhostForm

    Private InitialStyle As Integer
    Private PercentVisible As Decimal

    Public Property WS_EX_TRANSPARENT As Integer
    Declare Function GetWindowLong Lib "user32.dll" Alias "GetWindowLongA" (ByVal hwnd As System.IntPtr, ByVal nIndex As Integer) As Integer
    Declare Function SetWindowLong Lib "user32.dll" Alias "SetWindowLongA" (ByVal hwnd As System.IntPtr, ByVal nIndex As Integer, ByVal dwNewLong As Integer) As Integer
    Declare Function SetLayeredWindowAttributes Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal crKey As Integer, ByVal alpha As Byte, ByVal dwFlags As Integer) As Boolean

    Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        InitialStyle = GetWindowLong(Me.Handle, -20)
        PercentVisible = 0.5

        SetWindowLong(Me.Handle, -20, InitialStyle Or &H80000 Or &H20)
        SetLayeredWindowAttributes(Me.Handle, 0, 255 * PercentVisible, &H2)

        Me.TopMost = True

    End Sub

    Public Sub ClickHandler(sender As Object, e As MouseEventArgs) Handles Me.MouseClick, Label1.MouseClick, Button1.MouseClick
        Label1.Text = String.Format("Clicked ""{0}"" with the {1} mouse button.", sender.name, e.Button.ToString.ToLower)
        Select Case e.Button
            Case MouseButtons.Left
                Label1.Text = "Left"
            Case MouseButtons.Right
                Label1.Text = "Right"
            Case MouseButtons.Middle
                Label1.Text = "Middle"
            Case Else
                Label1.Text = "Some other button"
        End Select
    End Sub

    Private Sub GhostForm_Click(sender As Object, e As EventArgs) Handles Me.Click
        Console.Beep()
        Dim sp As New System.Media.SoundPlayer("C:\WINDOWS\MEDIA\Ding.wav")
        sp.Play()
        sp.Dispose()
    End Sub

End Class

点击表单后如何才能播放歌曲？

所以我重新表述我的问题。我有触摸屏，并且支持的驱动程序没有给我“蜂鸣声”选项，因此我想开发一个小型应用程序，让客户每次触摸触摸屏时都能听到蜂鸣声。为此，我必须创建一个透明表单，以便我可以单击表单后面的内容。然而，这段代码做得很完美，它不支持我的点击功能，因为点击会通过它。所以问题是：当我点击表单时如何获得音频输出？
