如何在C#中最小化和最大化窗口文件夹

Question

我正在尝试用语音(语音识别)最小化窗口文件夹和应用程序，这是我的代码：

 [DllImport("user32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool GetWindowPlacement(IntPtr hWnd, ref WINDOWPLACEMENT lpwndpl);
    [DllImport("user32.dll", SetLastError = true)]
    static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
    [DllImport("user32.dll")]
    static extern bool SetWindowPlacement(IntPtr hWnd, ref WINDOWPLACEMENT lpwndpl);

    private struct POINTAPI
    {
        public int x;
        public int y;
    }

    private struct RECT
    {
        public int left;
        public int top;
        public int right;
        public int bottom;
    }

    private struct WINDOWPLACEMENT
    {
        public int length;
        public int flags;
        public int showCmd;
        public POINTAPI ptMinPosition;
        public POINTAPI ptMaxPosition;
        public RECT rcNormalPosition;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        WindowAction_MinimizeNotepad();
    }

    void WindowAction_MinimizeNotepad()
    {
        System.IntPtr app_hwnd;
        WINDOWPLACEMENT wp = new WINDOWPLACEMENT();
        app_hwnd = FindWindow("chrome", null);
        GetWindowPlacement(app_hwnd, ref wp);
        wp.showCmd = 2;
        SetWindowPlacement(app_hwnd, ref wp);
    }

我知道如何使用带有按钮的代码，但我不知道如何将它用于语音识别，那么，如何最小化带有语音的窗口呢？谢谢。

Answer 1

首先，您需要注册语音识别事件，如: On Page load

// Register handler for the SpeechRecognized event. recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(srEvent_SpeechRecognized);

然后创建语音识别事件处理程序，如下所示：

void srEvent_SpeechRecognized(object sender, SpeechRecognizedEventArgs e) { this.WindowState = FormWindowState.Minimized; }

Answer 2

你可能想看看Microsoft.Speech.Recognition.SpeechRecognitionEngine.使用它，您可以订阅事件并继续对这些事件执行您想要执行的任何操作。欲了解更多信息，请访问https://msdn.microsoft.com/en-us/library/hh378426(v=office.14).aspx。
