如何在C＃中最小化和最大化窗口文件夾

Question

我正在嘗試最小化帶有語音（語音識別）的窗口文件夾和應用程序，這是我的代碼：

 [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);
    }

我知道如何在按鈕上使用該代碼，但是我不知道如何在語音識別中使用它，因此，如何最小化帶有語音的窗口？ 謝謝。

Answer 1

首先，您需要注冊以下語音識別事件：頁面加載

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

然后創建語音識別事件處理程序，例如：

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

Answer 2

您可能需要看看Microsoft.Speech.Recognition.SpeechRecognitionEngine 。 使用此功能，您可以訂閱事件並繼續執行想要對這些事件執行的任何操作。 在https://msdn.microsoft.com/zh-cn/library/hh378426(v=office.14).aspx上獲取更多信息。
