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
'注册全局热键
RegisterHotKey(Handle, 0, 0, Keys.F4)
'第3个参数意义： 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()
‘你想要的其它功能请添加到这里。
End If
MyBase.WndProc(m)
End Sub
