使用Windows 10 Creators Update,.NET 4.7或KB4034658在平板电脑上未触发WPF .NET应用程序崩溃,ComboBox和Menu事件

问题描述 投票:3回答:2

当我用ComboBox上的笔点击摇晃/紧张/锤击时,单击项目,移动笔,同时单击... 5或10分钟后控件停止工作。 然后我可以打开ComboBox,可以点击一个项目,项目会突出显示,但没有任何反应:ComboBox没有关闭,也没有点击事件被触发。 ContextMenu也会发生同样的错误。当错误发生时,所有ComboBox和所有菜单都不再起作用。当我用笔或用我的手指点击时,即使控件不再可用于笔或手指,鼠标也能正常工作。

在正常使用情况下,这种情况每个工作日大约发生5次,对我的用户来说非常烦人。您需要一些“耐心”来重现错误,也许需要超过10分钟...但它确实发生了。

我用一个ComboBox和一个带有ContextMenu的按钮制作了一个简单的测试应用程序,你可以用它重新产生错误。 我的应用程序的目标框架是4.6.1,使用VS2015编译。我的应用程序适用于Windows 8.1和Windows 10 Anniversary,使用.NET 4.6.1和4.6.2。

该错误发生在Microsoft Surface Pro 3和Pro 4上 - Windows 10 Creators更新(包括.NET 4.7) - 安装了Windows 10周年更新和.NET 4.7 - 已安装Windows 8.1和.NET 4.7 - 安装了Windows 10周年更新(.NET 4.6.2)和KB4034658!

对于前三个场景,我发现如何阻止Creator Update和.NET 4.7被Windows Update安装,至少在接下来的6个月内。 但是对于2017年8月的累积更新KB4034658,我的Windows 10用户的当前选项要么是要处理错误,要么完全停用所有Windows更新。

这是我的测试应用程序的代码:

MainWindow.xaml:

                <ComboBoxItem>ComboBoxItem 8</ComboBoxItem>
                <ComboBoxItem>ComboBoxItem 9</ComboBoxItem>
            </ComboBox>
            <Button x:Name="btnMenu" Content="MENU" FontSize="16" Margin="100,0,0,0">
                <Button.ContextMenu>
                    <ContextMenu>
                        <MenuItem Header="MenuItem 1"></MenuItem>
                        <MenuItem Header="MenuItem 2"></MenuItem>
                        <MenuItem Header="MenuItem 3"></MenuItem>
                        <MenuItem Header="MenuItem 4"></MenuItem>
                        <MenuItem Header="MenuItem 5"></MenuItem>
                        <MenuItem Header="MenuItem 6"></MenuItem>
                        <MenuItem Header="MenuItem 7"></MenuItem>
                        <MenuItem Header="MenuItem 8"></MenuItem>
                        <MenuItem Header="MenuItem 9"></MenuItem>
                    </ContextMenu>
                </Button.ContextMenu>
            </Button>
        </WrapPanel>
    </Grid>
</Window>

只有XAML,我的测试应用中绝对没有代码。

我的用户还报告,偶尔单击按钮在对话框窗口中不执行任何操作。发生这种情况时,他们只能点击右上方的关闭按钮;如上所述,下拉菜单和菜单在主窗口中不再起作用:它们需要关闭并重新启动应用程序。没有用样本再现这个,我想这是同样的错误。

此外,我的应用程序偶尔会崩溃与Windows 10 Creators Update或.NET 4.7,可能还与KB4034658崩溃。不幸的是,我不知道这些崩溃何时发生,但我怀疑它们在某种程度上与上述问题有关。

我在https://connect.microsoft.com/VisualStudiohttps://github.com/Microsoft/dotnet/issues报道了错误

我不希望得到这个错误的解决方案,但任何想法都是受欢迎的。

我想知道错误是否只发生在MS Surface上。我没有发现有关此错误的其他帖子,所以我会这么认为。没有很好的机会很快得到修复...... WPF和Surface - 太奇特了。

有了这篇文章,我希望一些拥有Surface的人会重新产生错误并向微软报告这个错误,以增加MS尽快修复它的可能性。另外,我想知道这个错误是仅在MS Surface平板电脑上还是在其他平板电脑上发生,可能只在High-DPI平板电脑上?

我们找到了一种解决方法,但它也有一些缺点。当disabling the RealTimeStylus在应用程序启动时,我们不能再重现该问题。

但是,禁用RealTimeStylus也会使用触摸禁用ScrollViewer swiping。它也可能影响手写笔的使用,我无法测试这一点。

虽然这种解决方案不是最佳解决方案,但对于您的情况(或至少是一个起点)可能就足够了。

    public static void DisableWPFTabletSupport()
    {
        // Get a collection of the tablet devices for this window.  
        TabletDeviceCollection devices = System.Windows.Input.Tablet.TabletDevices;

        if (devices.Count > 0)
        {
            // Get the Type of InputManager.
            Type inputManagerType = typeof(System.Windows.Input.InputManager);

            // Call the StylusLogic method on the InputManager.Current instance.
            object stylusLogic = inputManagerType.InvokeMember("StylusLogic",
                        BindingFlags.GetProperty | BindingFlags.Instance | BindingFlags.NonPublic,
                        null, InputManager.Current, null);

            if (stylusLogic != null)
            {
                //  Get the type of the device class.
                Type devicesType = devices.GetType();

                // Loop until there are no more devices to remove.
                int count = devices.Count + 1;

                while (devices.Count > 0)
                {
                    // Remove the first tablet device in the devices collection.
                    devicesType.InvokeMember("HandleTabletRemoved", BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.NonPublic, null, devices, new object[] { (uint)0 });

                    count--;

                    if (devices.Count != count)
                    {
                        throw new Win32Exception("Unable to remove real-time stylus support.");
                    }
                }
            }
        }
    }

这个问题有点回来,但我对“不再响应GUI”有一个解释。

如果项目在列表视图中没有100%可见(已存放)并且您执行了单击,则列表视图会首先滚动项目完全可见。一切都适用于鼠标。但TouchUp事件在滚动之前就会触发。这正是错误发生的地方。我通过等待“Click-Event”来绕过这个,无论是触摸还是鼠标,10ms然后才执行我的动作。因此,错误是我固定的。
