打开和关闭桌面下的Windows 8触摸键盘选项卡

Question

我需要从Windows8（桌面winform.NET）下的程序中关闭tabtip键盘。我发现可以在需要的时候打开它，运行TabTip.exe来显示Windows 8 Touch键盘，但我无法在需要时关闭它！我试着用process.kill来终止这个过程，但它不起作用，有人知道怎么做？

Answer 1

Tabtip.exe打开，然后生成两个进程，然后再次关闭。因此process.kill命令不起作用，因为原始进程已经关闭。

这将查看所有打开的进程，并关闭任何与tabtip相关的进程。

For Each pkiller As Process In Process.GetProcesses
      If String.Compare(pkiller.ProcessName, "tabtip", True) = 0 Then
          pkiller.Kill()
      End If
Next

Answer 2

尝试以下操作-用TabTip 替换Osk

公共类Form1

Private oskProcess As Process
Private Sub openButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles openButton.Click
    If Me.oskProcess Is Nothing OrElse Me.oskProcess.HasExited Then
        If Me.oskProcess IsNot Nothing AndAlso Me.oskProcess.HasExited Then
            Me.oskProcess.Close()
        End If
        Me.oskProcess = Process.Start("osk")
    End If
End Sub
Private Sub closeButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles closeButton.Click
    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
        Me.oskProcess.Close()
        Me.oskProcess = Nothing
    End If
End Sub
