C# WebBrowser控件中的虚拟Win8键盘

我目前正在WPF中做一个触摸应用程序。到目前为止，它工作得很好，但有时我需要启动内置的web浏览器控件。我的问题是，尽管缩放、滚动等功能正常工作，但当用户关注web文本输入时，我无法让Windows 8虚拟键盘（如IE 11）显示出来

有没有办法达到这种行为？请记住，我的WPF应用程序应该一直运行在最顶端，完全全屏，所以我不能要求用户手动打开虚拟键盘

终于找到了。。。如前所述，Winforms WebBrowser具有更好的HTMLDocument包装器，这比使用MSHTML互操作更容易。下面是一段代码片段：

C#：

public partial class BrowserWindow : Window
        {
            public BrowserWindow(string url)
            {
                InitializeComponent();
                WebView.ScriptErrorsSuppressed = true;
                WebView.AllowNavigation = true;
                WebView.Navigate(new Uri(url));
                WebView.DocumentCompleted += LoadCompleteEventHandler;
            }

            private void LoadCompleteEventHandler(object sender, WebBrowserDocumentCompletedEventArgs navigationEventArgs)
            {
                HtmlElementCollection elements = this.WebView.Document.GetElementsByTagName("input");
                foreach (HtmlElement input in elements)
                {
                    if (input.GetAttribute("type").ToLower() == "text")
                    {
                        input.GotFocus += (o, args) => VirtualKeyBoardHelper.AttachTabTip();
                        input.LostFocus += (o, args) => VirtualKeyBoardHelper.RemoveTabTip();
                    }
                }
            }
        }

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
        x:Class="PlayPlatform.BrowserWindow"
        Title="Browser" ResizeMode="NoResize"

    <WindowsFormsHost HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <wf:WebBrowser x:Name="WebView" />
    </WindowsFormsHost>
</Window>

XAML：

public partial class BrowserWindow : Window
        {
            public BrowserWindow(string url)
            {
                InitializeComponent();
                WebView.ScriptErrorsSuppressed = true;
                WebView.AllowNavigation = true;
                WebView.Navigate(new Uri(url));
                WebView.DocumentCompleted += LoadCompleteEventHandler;
            }

            private void LoadCompleteEventHandler(object sender, WebBrowserDocumentCompletedEventArgs navigationEventArgs)
            {
                HtmlElementCollection elements = this.WebView.Document.GetElementsByTagName("input");
                foreach (HtmlElement input in elements)
                {
                    if (input.GetAttribute("type").ToLower() == "text")
                    {
                        input.GotFocus += (o, args) => VirtualKeyBoardHelper.AttachTabTip();
                        input.LostFocus += (o, args) => VirtualKeyBoardHelper.RemoveTabTip();
                    }
                }
            }
        }

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
        x:Class="PlayPlatform.BrowserWindow"
        Title="Browser" ResizeMode="NoResize"

VirtualKeyBoardHelper方法是手动启动和终止tabtip.exe。

在哪里找到VirtualKeyBoardHelper的？明白了！这是你自己的课。谢谢
