如何在单击鼠标左键时禁用按住按住Alt键，Ctrl键和Shift键

概述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,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);
