如何在单击鼠标左键时禁用按住/按住Alt键,Ctrl键和Shift键

我试图做一个程序,阻止一些Windows热键和类似的function,以帮助用户避免做一个动作,他们可能不想在一个浏览器中运行的Flash程序。

我希望做的程序将是一个.NET C#WinForms程序,作为一个键盘钩子。

目前,它可以阻止按键组合,如Ctrl + W,Alt + F4。 但这些只是“次要function”。 他们正在使用RegisterHotkey方法工作。

我真正想要实现的是,如果可能,以任何方式禁用Ctrl +鼠标左键单击 ,按住Alt +鼠标左键单击Shift +鼠标左键单击

实现它的方法还应该最好“解除”它们,并在程序closures时重新启用它们。

这是当前代码的相关片段:

我知道这可能与SetWindowsHookEx方法有关,但是我不知道如何使用它来实现它。

如果实现它的最好方法不会与我现有的代码冲突,并且可以和它一起工作。

我也试图确保这个程序可以兼容Windows XP的所有版本,如果可能的话,可以同时使用32位和64位。 我在Windows 8 Professional 64位计算机上使用Visual Studio 2010 Professional。

我希望这将是足够具体的? 这是我第一次在这里发帖…(尽pipe我已经在过去多次search过这个网站)

(我曾尝试使用“RegisterGlobalHotKey(Keys.LButton,USE_CTRL)”,“RegisterGlobalHotKey(Keys.LButton,USE_ALT)”和“RegisterGlobalHotKey(Keys.LButton,USE_SHIFT)”,但它们根本不起作用。

我相信我很早以前就已经找到了解决我的问题的办法,也似乎没有人知道如何解决这个问题。

我还没有亲自测试过这个,但是如果我将http://www.codeproject.com/Articles/32556/Auto-Clicker-C和下面的代码结合起来使用鼠标点击检测功能&#xFF0C;

 [StructLayout(LayoutKind.Sequential)] public struct INPUT { public SendInputEventType type; public KeybdInputUnion mkhi; } [StructLayout(LayoutKind.Explicit)] public struct KeybdInputUnion { [FieldOffset(0)] public KEYBDINPUT ki; } [StructLayout(LayoutKind.Sequential)] public struct KEYBDINPUT { public ushort wVk; public ushort wScan; public uint dwFlags; public uint time; public IntPtr dwExtraInfo; } public enum SendInputEventType : int { InputKeyboard } public enum KeyCode : ushort { /// <summary> /// Right shift /// </summary> RSHIFT = 0xa1, /// <summary> /// Shift key /// </summary> SHIFT = 0x10, /// <summary> /// Right control /// </summary> RCONTROL = 0xa3, /// <summary> /// Left control /// </summary> LCONTROL = 0xa2, /// <summary> /// Left shift /// </summary> LSHIFT = 160, /// <summary> /// Ctlr key /// </summary> CONTROL = 0x11, /// <summary> /// Alt key /// </summary> ALT = 18, } [DllImport("User32.dll", SetLastError = true)] static extern uint SendInput(uint nInputs, ref INPUT pInputs, int cbSize); void YourMethodHereLikeTimerTickOrWE() { if (Control.ModifierKeys == Keys.Shift) { SendKeyUp(KeyCode.SHIFT); } if (Control.ModifierKeys == Keys.Alt) { SendKeyUp(KeyCode.ALT); } if (Control.ModifierKeys == Keys.Control) { SendKeyUp(KeyCode.CONTROL); } if (Control.ModifierKeys == (Keys.Control | Keys.Shift)) { SendKeyUp(KeyCode.CONTROL); SendKeyUp(KeyCode.SHIFT); } if (Control.ModifierKeys == (Keys.Control | Keys.Alt)) { SendKeyUp(KeyCode.CONTROL); SendKeyUp(KeyCode.ALT); } if (Control.ModifierKeys == (Keys.Alt | Keys.Shift)) { SendKeyUp(KeyCode.ALT); SendKeyUp(KeyCode.SHIFT); } if (Control.ModifierKeys == (Keys.Alt | Keys.Shift | Keys.Control)) { SendKeyUp(KeyCode.ALT); SendKeyUp(KeyCode.SHIFT); SendKeyUp(KeyCode.CONTROL); } } public static void SendKeyUp(KeyCode keyCode) { INPUT input = new INPUT { type = SendInputEventType.InputKeyboard, }; input.mkhi.ki = new KEYBDINPUT(); input.mkhi.ki.wVk = (ushort)keyCode; input.mkhi.ki.wScan = 0; input.mkhi.ki.dwFlags = 2; input.mkhi.ki.time = 0; input.mkhi.ki.dwExtraInfo = IntPtr.Zero; //INPUT[] inputs = new INPUT[] { input }; if (SendInput(1, ref input, Marshal.SizeOf(typeof(INPUT))) == 0) throw new Exception(); } 

这应该是理论上的工作。 到目前为止,我已经单独使用了两个部分,没有任何问题。

此外,从CodeProject的代码,为一个特定的方法调用

 private static void EnsureSubscribedToGlobalMouseEvents() 

在那里有一行代码必须被改变,才能在C#NET 4 Framework中正确使用。

即代码

 s_MouseHookHandle = SetWindowsHookEx( WH_MOUSE_LL, s_MouseDelegate, Marshal.GetHINSTANCE( Assembly.GetExecutingAssembly().Getmodulees()[0]), 0); 

应该改成这样:

 s_MouseHookHandle = SetWindowsHookEx( WH_MOUSE_LL, s_MouseDelegate, LoadLibrary("user32.dll"), 0); 

为了使用LoadLibrary,你需要在下面调用这个P / Invoke:

 [DllImport("kernel32", SetLastError = true, CharSet = CharSet.Ansi)] static extern IntPtr LoadLibrary([MarshalAs(UnmanagedType.LPStr)]string lpFileName);
