Public Class Form1

    Public Declare Auto Function RegisterHotKey Lib "user32.dll" Alias "RegisterHotKey" (ByVal hwnd As IntPtr, ByVal id As Integer, ByVal fsModifiers As Integer, ByVal vk As Integer) As Boolean

    Public Declare Auto Function UnRegisterHotKey Lib "user32.dll" Alias "UnregisterHotKey" (ByVal hwnd As IntPtr, ByVal id As Integer) As Boolean

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        '注冊全局熱鍵 

        RegisterHotKey(Handle, 0, 0, Keys.F4)

        '第3個參數意義： 0=nothing 1 -alt 2-ctrl 3-ctrl+alt 4-shift 5-alt+shift 6-ctrl+shift 7-ctrl+shift+alt

    End Sub

    Private Sub Form1_Closed(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Closed

        UnRegisterHotKey(Handle, 0)

    End Sub

    Protected Overrides Sub WndProc(ByRef m As Message)

        If m.Msg = 786 Then

            Me.Activate()

‘你想要的其它功能請添加到這裏。

        End If

        MyBase.WndProc(m)
