Description
C'est un contrôle qui hérite de la classe ButtonBase. Je lui ai rajouté la possibilité de jouer un fichier wav sur les événements de la souris : Enter, Leave, Click, MouseUp, MouseDown
Source / Exemple :
Imports System.Drawing.Drawing2D
Public Class AudioBtn
Inherits System.Windows.Forms.Button
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
'We add the different handlers
AddHandler Me.MouseEnter, AddressOf PlayMouseEnterSound
AddHandler Me.MouseLeave, AddressOf PlayMouseLeaveSound
AddHandler Me.Click, AddressOf PlayMouseClickSound
AddHandler Me.MouseDown, AddressOf PlayMouseDownSound
AddHandler Me.MouseUp, AddressOf PlayMouseUpSound
End Sub
'UserControl1 overrides dispose to clean up the component list.

If disposing Then
If Not (components Is Nothing) Then

End If
