Как захватить содержимое окна под названием 3D-приложений, таких как Roblox C #? - PullRequest
0 голосов
/ 12 октября 2019

Я пытаюсь запустить все оконные приложения с компьютера и вывести их список. Когда пользователь нажимает на элемент списка, я хочу сделать скриншот содержимого этого приложения. В настоящее время этот код работает в не трехмерных приложениях, таких как консоли, визуальный код и случайные частичные окна. Как заставить это работать на 3D-приложениях, таких как Roblox?

    public AutoClicker()
    {
        InitializeComponent();
    }


    private void AutoClicker_Load(object sender, EventArgs e)
    {
        this.OpenWindowListBox.Items.AddRange(Helpers.Utilities.GetProcesses(""));
    }

    private void OpenWindowListBox_SelectedValueChanged(object sender, EventArgs e)
    {
        Process aProcess = this.OpenWindowListBox.SelectedItem as Process;
        ScreenCapture sc = new ScreenCapture();
        WindowPreview.Image = sc.CaptureWindow(aProcess.Handle);
    }
