'窗体放上控件：Command1、Label1、Check1、Check2、Text1、Text2、Timer1
'加入以下代码，运行，设置"确定"键的快捷键
'可选"CTRL+某键"或者"SHIFT+某键"

vb.net 全局热键
见下面的代码
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()
End If
MyBase.WndProc(m)
End Sub
End Class
VB .net中如何调用底层键盘钩子或其他方法屏蔽全局所有按键
.net的代码真木有写过。
VB 可以屏蔽 包括ctrl+alt+del在内的所有键盘按键消息
其实你只要后台截获按键的消息后，直接屏蔽掉就可以了。
VB代码我有 net木有。
