c# - 在windows c#中的进程中调用右键单击菜单

Question

过去 3 天我一直在尝试在网上和自己寻找解决方案。找到了很多相关 Material ，但没有任何 Material 适合我的情况。我通过以下代码启动了一个新进程，它是 Windows 语音识别应用程序，我想以编程方式调用其右键菜单中的选项之一。

我已经测试过了Postmessage、Sendmessage 和 sendClick 事件，它们都不起作用。

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        [DllImport("User32.dll")]
        public static extern int SetForegroundWindow(IntPtr point);

        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        static extern IntPtr FindWindow(string lpClass, string lpW);

        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        static extern IntPtr SendMessage(IntPtr hWnd, uint msg, IntPtr wParam, IntPtr lParam);
        [return: MarshalAs(UnmanagedType.Bool)]
        [DllImport("user32.dll", SetLastError = true)]
        public static extern void PostMessage(IntPtr hWnd, int msg, int wParam, int lParam);

        public Form1()
        {
            //InitializeComponent();

            const int WM_COMMAND = 0x0111; 
            Process proc = new Process();

            proc.StartInfo.FileName = @"C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessibility\Speech Recognition.lnk";

            proc.Start(); 
            Thread.Sleep(200);   
            IntPtr Window = FindWindow(null, "Speech Recognition");

            SetForegroundWindow(Window);

            SendKeys.SendWait("{Move 200,200}");
        }
    }
}

假设你想打开语音词典你可以通过

• 运行命令行:SpeechUXWiz.exe VocabularyManager

• 使用 API:Add new word to windows speech recognition using C#

  You'll need to use the SAPI Automation APIs (aka SpeechLib) to access the ISpLexicon interfaces.

  In particular, ISpLexicon::AddPronunciation will add a new word (and its associated pronunciation) to the user lexicon.
