如何使用 Microsoft uiautomation 检查复选框？

Question

我需要自动化 madvr gui 并使用 uiautomation 实现平滑运动。
但是找不到最近的和简单的工作示例。

madvr window 身份：

madvr smooth motion复选框标识：

我的实际代码：

using System;
using System.Diagnostics;

namespace MadAutomation
{
    class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Enabling the madvr smooth motion feature...");

            EnableSmoothMotion();

            Console.Write("Press any key to continue...");
            Console.ReadKey(true);
        }

        public static void EnableSmoothMotion()
        {
            // Run madvr configuration.         
            Process p = new Process();
            p.StartInfo.FileName = @"C:\Users\Admin\Desktop\madVR\madHcCtrl.exe";
            p.StartInfo.Arguments = "editLocalSettingsDontWait";
            p.Start();

            // Enable smooth motion checkbox.
        }
    }
}

这是一个执行此操作的程序。请注意，您必须使用 NuGet UIAComWrapper 程序包（由 Microsoft 人员编写）而不是 UIAutomation*.dll 提供的标准 out-of-the-box上班。标准 UIA .NET 程序集看不到所有 AutomationElement，不知道所有属性（Aria 等）。

是的，这意味着它们是 bugged/obsolete 并且出于某种原因，Microsoft 并未正式发布带有新 .NET 或 Windows 版本的较新版本...无论如何，UIAComWrapper 是 100% source-compatible drop-in 的替代品，所以这应该不是问题。

如果您想查看 UIAComWrapper 与 UIA 组件返回的内容之间的差异，您将看到的差异与使用 Inspect（官方UI工具）和UISpy（官方UI工具已过时）。它们看起来很相似，但实际上在细节或结构上有很大不同。

public static void EnableSmoothMotion()
{
    bool finished = false;
    // wait for the settings window to show
    Automation.AddAutomationEventHandler(WindowPattern.WindowOpenedEvent, AutomationElement.RootElement, TreeScope.Children, (sender, e) =>
    {
        var window = (AutomationElement)sender;
        if (window.Current.ClassName != "TFMadVRSettings")
            return;

        // get the tree element
        var tree = window.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Tree));

        // get the smooth motion element & select it
        var smoothMotion = tree.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "smooth motion"));
        ((SelectionItemPattern)smoothMotion.GetCurrentPattern(SelectionItemPattern.Pattern)).Select();

        // get the tab element
        var tab = window.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Tab));

        // get the pane element
        var pane = tab.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Pane));

        // get the first checkbox & ensure it's clicked
        var cb = pane.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.CheckBox));
        TogglePattern tp = (TogglePattern)cb.GetCurrentPattern(TogglePattern.Pattern);
        if (tp.Current.ToggleState != ToggleState.On) // not on? click it
        {
            ((InvokePattern)cb.GetCurrentPattern(InvokePattern.Pattern)).Invoke();
        }

        // NOTE: uncomment the two following line if you want to close the window directly
        // get the ok button & push it
        //var ok = window.FindFirst(TreeScope.Children, new AndCondition(
        //    new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button),
        //    new PropertyCondition(AutomationElement.NameProperty, "OK")));
        //((InvokePattern)ok.GetCurrentPattern(InvokePattern.Pattern)).Invoke();

        finished = true;
    });

    // run the program
    Process p = new Process();
    p.StartInfo.FileName = @"C:\Users\Admin\Desktop\madVR\madHcCtrl.exe";
    p.StartInfo.Arguments = "editLocalSettingsDontWait";
    p.Start();

    while(!finished)
    {
        Thread.Sleep(100);
    }
    Automation.RemoveAllEventHandlers();
}

注意：我在这里使用了事件处理程序而不是process.MainWindowHandle，因为进程的主要window不是设置window，而设置window是不是主要 window.
