VSTO Word插件-检测鼠标点击

Question

我正在开发一个VSTO Word插件。vsto外接程序是否可以检测用户是否在文档区域之外单击。

如下图所示:检测我是否点击了黑框内的任何地方(功能区和底部区域)

​

​

我不需要知道正在点击的控件是什么…只要点击发生在这两个黑盒里。

我有办法做到这一点吗？谢谢。

Private Function MouseHookCallback(ByVal nCode As Integer, ByVal wParam As IntPtr, ByVal lParam As IntPtr) As IntPtr
    If nCode = 0 Then
        Dim mouseHookStruct = CType(Marshal.PtrToStructure(lParam, GetType(SafeNativeMethods.MouseHookStructEx)), SafeNativeMethods.MouseHookStructEx)
        Dim message = CType(wParam, SafeNativeMethods.WindowMessages)
        Debug.WriteLine("{0} event detected at position {1} - {2}", message, mouseHookStruct.pt.X, mouseHookStruct.pt.Y)
        If message = WindowMessages.WM_LBUTTONDOWN Or message = WindowMessages.WM_MBUTTONDOWN Or message = WindowMessages.WM_RBUTTONDOWN Or _
            message = WindowMessages.WM_MOUSEHWHEEL Or message = WindowMessages.WM_MOUSEWHEEL Then
            'do something here
        End If
        If message = WindowMessages.WM_MOUSEMOVE Then
            Debug.WriteLine("mouse move!!!!!!!!!!!!!!!!!!a with ncode=> " & nCode)
        End If
    End If

    Return SafeNativeMethods.CallNextHookEx(_hookIdKeyboard, nCode, wParam, lParam)
End Function

VSTO没有为此提供任何东西。但是你可以尝试设置一个键盘钩子，更多信息请参见Low-Level Keyboard Hook in C#。

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

class InterceptKeys
{
    private const int WH_KEYBOARD_LL = 13;
    private const int WM_KEYDOWN = 0x0100;
    private static LowLevelKeyboardProc _proc = HookCallback;
    private static IntPtr _hookID = IntPtr.Zero;

    public static void Main()
    {
        _hookID = SetHook(_proc);
        Application.Run();
        UnhookWindowsHookEx(_hookID);
    }

    private static IntPtr SetHook(LowLevelKeyboardProc proc)
    {
        using (Process curProcess = Process.GetCurrentProcess())
        using (ProcessModule curModule = curProcess.MainModule)
        {
            return SetWindowsHookEx(WH_KEYBOARD_LL, proc,
                GetModuleHandle(curModule.ModuleName), 0);
        }
    }

    private delegate IntPtr LowLevelKeyboardProc(
        int nCode, IntPtr wParam, IntPtr lParam);

    private static IntPtr HookCallback(
        int nCode, IntPtr wParam, IntPtr lParam)
    {
        if (nCode >= 0 && wParam == (IntPtr)WM_KEYDOWN)
        {
            int vkCode = Marshal.ReadInt32(lParam);
            Console.WriteLine((Keys)vkCode);
        }
        return CallNextHookEx(_hookID, nCode, wParam, lParam);
    }

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr SetWindowsHookEx(int idHook,
        LowLevelKeyboardProc 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);
}
