如何从c#开发的Word 2010插件中"捕获"KeyPress事件?

注意:我不是在寻找"复杂"的解决方案，比如挂钩的东西，而是为了美观和整洁. net甚至从对象模型。

我"in my hands"的应用对象是:

Microsoft.Office.Interop.Word.Application

如何获得“按键”?事件来自Word 2010插件(c#开发)

不幸的是，在Word API或VSTO中没有任何内置的可以拾取击键，更多信息可以在这里找到

我一直在寻找一个可行的解决方案一段时间，但我能想到的最好的是通过Windows API使用钩子来处理它，很可能你会得到同样的结论，所以这里有一个例子:

你需要在以下程序集中添加一个using指令:

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Threading;
using System.Windows.Forms;

这里是钩子:

   public partial class ThisAddIn
    {
        private const int WH_KEYBOARD_LL = 13;
        private const int WM_KEYDOWN = 0x0100;
        private static IntPtr hookId = IntPtr.Zero;
        private delegate IntPtr HookProcedure(int nCode, IntPtr wParam, IntPtr lParam);
        private static HookProcedure procedure = HookCallback;
        [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern IntPtr GetModuleHandle(string lpModuleName);
        [DllImport("user32.dll", SetLastError = true)]
        private static extern bool UnhookWindowsHookEx(IntPtr hhk);
        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern IntPtr SetWindowsHookEx(int idHook, HookProcedure lpfn, IntPtr hMod, uint dwThreadId);
        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode, IntPtr wParam, IntPtr lParam);  
        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            hookId = SetHook(procedure);
        }
        private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
        {
            UnhookWindowsHookEx(hookId);
        }
        private static IntPtr SetHook(HookProcedure procedure)
        {
            using (Process process = Process.GetCurrentProcess())
            using (ProcessModule module = process.MainModule)
                return SetWindowsHookEx(WH_KEYBOARD_LL, procedure, GetModuleHandle(module.ModuleName), 0);
        }
        private static IntPtr HookCallback(int nCode, IntPtr wParam, IntPtr lParam)
        {
            if (nCode >= 0 && wParam == (IntPtr)WM_KEYDOWN)
            {
                int pointerCode = Marshal.ReadInt32(lParam);
                string pressedKey = ((Keys)pointerCode).ToString();
                //Do some sort of processing on key press
                var thread = new Thread(() => { MessageBox.Show(pressedKey); });
                thread.Start();
            }
            return CallNextHookEx(hookId, nCode, wParam, lParam);
        }
        private void InternalStartup()
        {
            this.Startup += new System.EventHandler(ThisAddIn_Startup);
            this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
        }
    }

您可以尝试使用Excel WebBrowser控件而不是System.Windows.Forms WebBrowser;它处理特殊的键转发如TAB, DEL, CTRL+V等

将WebBrowser的构造函数从

更改
new System.Windows.Forms.WebBrowser();


new Microsoft.Office.Tools.Excel.Controls.WebBrowser();

你需要添加引用到你的项目:项目/添加引用/扩展选择Microsoft.Tools.Outlook &Microsoft.Tools.Outlook.v4.0.Utilities
