某些应用我们希望全局自定义热键。按键少了会和别的应用程序冲突按键多了可定用户操作不变。因此我计划左手用CtrlAlt右手用鼠标右键呼出我自定义的菜单。
我使用键盘和鼠标事件进行简单测试Ctrl鼠标右键发现并不能成功。
RegisterHotKey(hWnd, HOTKEY_ID, (int)Modifiers.Control, (int)Keys.RButton);
因此只好使用“钩子”。
二、添加引用
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Diagnostics;
三、定义变量
private const int WH_MOUSE_LL 14;
private const int WM_RBUTTONDOWN 0x0204;
private const int VK_CONTROL 0x11;
private const int VK_MENU 0x12;
private HookProc mouseProc;
private IntPtr hookId IntPtr.Zero;
public event EventHandler HotkeyPressed;
四、编写过程
private IntPtr SetMouseHook(HookProc proc)
{using (Process curProcess Process.GetCurrentProcess())using (ProcessModule curModule curProcess.MainModule){return SetWindowsHookEx(WH_MOUSE_LL, proc, GetModuleHandle(curModule.ModuleName), 0);}
}
private IntPtr MouseHookCallback(int nCode, IntPtr wParam, IntPtr lParam)
{if (nCode 0 wParam (IntPtr)WM_RBUTTONDOWN){int ctrl_keyState GetAsyncKeyState(VK_CONTROL);int alt_keyState GetAsyncKeyState(VK_MENU);// 检查Ctrl键和Alt键是否同时按下if ((ctrl_keyState 0) (alt_keyState 0)) {HotkeyPressed?.Invoke(this, EventArgs.Empty);// 返回非零值以阻止事件传递给其他窗口return new IntPtr(1);}}return CallNextHookEx(hookId, nCode, wParam, lParam);
}
private delegate IntPtr HookProc(int code, IntPtr wParam, IntPtr lParam);
[DllImport(user32.dll, CharSet CharSet.Auto, SetLastError true)]
private static extern IntPtr SetWindowsHookEx(int idHook, HookProc lpfn, IntPtr hMod, uint dwThreadId);[DllImport(user32.dll, CharSet CharSet.Auto, SetLastError true)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool UnhookWindowsHookEx(IntPtr hhk);[DllImport(user32.dll, CharSet CharSet.Auto, SetLastError true)]
private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode, IntPtr wParam, IntPtr lParam);[DllImport(kernel32.dll, CharSet CharSet.Auto, SetLastError true)]
private static extern IntPtr GetModuleHandle(string lpModuleName);[DllImport(user32.dll, CharSet CharSet.Auto, SetLastError true)]
private static extern short GetAsyncKeyState(int vKey);private void HotkeyExample_HotkeyPressed(object sender, EventArgs e)
{Console.WriteLine(CtrlAlt鼠标右键被按下);// 可以执行其他操作...if (this.WindowState FormWindowState.Minimized){POINT M_Point GetMousePosition();this.WindowState FormWindowState.Normal;}else{this.WindowState FormWindowState.Minimized;}
}
五、调用
private void Form1_Load(object sender, EventArgs e)
{this.HotkeyPressed HotkeyExample_HotkeyPressed;mouseProc MouseHookCallback;hookId SetMouseHook(mouseProc);}
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{UnhookWindowsHookEx(hookId);
}
六、运行效果 通过以上代码自定义窗体顺利弹出而且并不会与别的程序冲突满足了需求。
