Tabtip和InputScope - 显示数字键盘

Question

我有一台平板电脑，必须使用数字输入字段运行应用程序。但是，我无法使Windows键盘（TabTip.exe）在默认情况下弹出显示数字键盘。

当文本框被点击时，键盘需要自动弹出。

我设法让它通过在TextBox事件处理程序中运行TabTip.exe来显示每个字段上的键盘，但它显示正常的键盘布局。这是利用这个问题的答案：Show & hiding the Windows 8 on screen keyboard from WPF

protected override void OnStartup(StartupEventArgs eventArgs) 
    { 

     // Popup keyboard, Select All on getting focus. 
     EventManager.RegisterClassHandler(typeof(TextBox), UIElement.GotFocusEvent, 
           new RoutedEventHandler(GotFocus_Event), true); 
     EventManager.RegisterClassHandler(typeof(TextBox), UIElement.LostFocusEvent, 
           new RoutedEventHandler(LostFocus_Event), true); 

    } 

    private static void GotFocus_Event(object sender, RoutedEventArgs e) 
    { 
     // The popup keyboard. 
     OpenTouchKeyboard(sender, e); 
    } 

    private static void OpenTouchKeyboard(object sender, RoutedEventArgs e) 
    { 
     var textBox = e.OriginalSource as TextBox; 
     if (textBox != null && IsSurfaceKeyboardAttached()) 
     { 
      var path = @"C:\Program Files\Common Files\Microsoft Shared\ink\TabTip.exe"; 
      Process.Start(path); 
      textBox.BringIntoView(); 
     } 
    } 

我在以下页面，您可以使用文本框的“InputScope”属性决定了它应该是一个数字键盘读取。

https://msdn.microsoft.com/nl-nl/library/windows/apps/xaml/mt280229?f=255&MSPPError=-2147217396#touch_keyboard_index_for_windows_and_windows_phone

因此，像<TextBox Header="Name" InputScope="Number"/>

然而，这没有任何影响，但它仍然与常规布局弹出。另外，我发现很难相信InputScope只是将自己传递给TabTip.exe进程的执行，而没有以某种方式将它们连接起来。

我也碰到过这样的：Start TabTip with numpad view open这表明编辑每次调用TabTip.exe注册表之前，但这似乎很凌乱，并且在Windows显然是不可靠的10

是不是有一个命令行参数还是可以传递给它的东西？

我找到了答案，谢谢MSDN，它指出我的Automatic Touch Keyboard。

所以基本上我已经去了错误的方式

做正确的方法：添加引用InputPanelConfigurationLib.dll和UIAutomationClient.dll

然后禁用正是如此墨水输入...

using System; 
using System.Reflection; 
using System.Windows.Input; 

namespace ModernWPF.Win8TouchKeyboard.Desktop 
{ 
    public static class InkInputHelper 
    { 
     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 stylusLogic returned from the call to StylusLogic. 
        Type stylusLogicType = stylusLogic.GetType(); 

        // Loop until there are no more devices to remove. 
        while (devices.Count > 0) 
        { 
         // Remove the first tablet device in the devices collection. 
         stylusLogicType.InvokeMember("OnTabletRemoved", 
           BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.NonPublic, 
           null, stylusLogic, new object[] { (uint)0 }); 
        } 
       } 
      } 
     } 
    } 
} 

并在MainWindow.xaml.cs ...

public MainWindow() 
{ 
    InitializeComponent(); 

    // Disables inking in the WPF application and enables us to track touch events to properly trigger the touch keyboard 
    InkInputHelper.DisableWPFTabletSupport(); 

    this.Loaded += MainWindow_Loaded; 
} 

private void MainWindow_Loaded(object sender, RoutedEventArgs e) 
{ 

    System.Windows.Automation.AutomationElement asForm = 
     System.Windows.Automation.AutomationElement.FromHandle(new WindowInteropHelper(this).Handle); 


    InputPanelConfigurationLib.InputPanelConfiguration inputPanelConfig = new InputPanelConfigurationLib.InputPanelConfiguration(); 
    inputPanelConfig.EnableFocusTracking(); 
} 

而且你看，选择一个文本框调出键盘。但是，现在，它注意到InputScope，如果我设置为Number，则会显示数字小键盘。
