.net – 在桌面下打开和关闭Windows 8触摸键盘tabtip

我需要从 Windows 8(桌面winform .NET)下的程序中关闭tabtip键盘.
我发现需要时打开它,运行TabTip.exe来显示Windows 8 Touch键盘,但我无法在需要时关闭它！
我试图用process.kill来杀死这个过程,但是它没有用,有人知道怎么做了吗？

问候

    If Me.oskProcess IsNot Nothing Then
        If Not Me.oskProcess.HasExited Then
            'CloseMainWindow would generally be preferred but the OSK doesn't respond.
            Me.oskProcess.Kill()
        End If
