如何禁用或锁定Windows按钮？

Answer 1

你需要一个键盘钩子。从这样的地方开始：

 hKeyboardHook = SetWindowsHookEx(WH_KEYBOARD, KeyboardProc, hInstance, 0);

并继续这样：

  LRESULT KeyboardProc(...)
  {
     if (Key == VK_SOMEKEY)
    return 1;             // Trap key


    return CallNextHookEx(...); // Let the OS handle it

  }

使用Windows钩子比修改注册表要简洁得多。此外，有时人们已经设置了自己的个性化扫描码地图，并且覆盖它们并不是一件好事。

要使用Windows键挂钩功能，您需要DllImport一对winapi函数：

[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern IntPtr GetModuleHandle(string lpModuleName);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern IntPtr SetWindowsHookEx(int idHook, HookHandlerDelegate lpfn, IntPtr hMod, uint dwThreadId);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool UnhookWindowsHookEx(IntPtr hhk);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode, IntPtr wParam, ref KBDLLHOOKSTRUCT lParam);

[DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true, CallingConvention = CallingConvention.Winapi)]
public static extern short GetKeyState(int keyCode);

可以在CodeProject找到相当完整的解释和演练。这是一个direct link来自该示例的自包含类文件，它执行所有操作（如果您使用WPF将其编译为干净，则需要您手动引用System.Windows.Forms dll或仅更改'System .Windows.Forms.Keys对System.Windows.Input.Key的引用应该有效。

请记得调用UnhookWindowsHookEx（）（该类在Dispose（）中执行此操作）以取消捕获您的捕获，否则人们会讨厌您。

假设您希望永久禁用Windows密钥，而不仅仅是在代码处于焦点时，那么您可以通过编辑注册表来执行此操作，如下所示：

要停用：将名为“扫描码地图”的新 REG_BINARY 值添加到“ HKEY_LOCAL_ MACHINE \ System \ CurrentControlSet \ Control \ Keyboard Layout ”，数据值为“的 00000000000000000300000000005BE000005CE000000000 ”

启用：完全从注册表中删除“扫描码映射”值。
