推荐答案

如果您正在谈论虚拟键盘COM组件，请 ^ ]包含一些信息.

If you are talking about the Virtual Keyboard COM component, then this[^] has some info.

我刚刚尝试了以下操作，效果很好；

I have just tried the following and it works fine;

Public Class Form1
    Private OSK As System.Diagnostics.Process
Private Sub ButtonShowOSK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonShowOSK.Click
        'Create the OSK Process
    OSK = System.Diagnostics.Process.Start("osk.exe")
End Sub

Private Sub ButtonKillOSK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonKillOSK.Click
    Try
        OSK.Kill()
    Catch ex As Exception
        Debug.WriteLine(ex.Message)
    End Try
End Sub
End Class

注意1:OSK进程具有CloseMainWindow()方法，但是，它返回true,表示成功，但是OSK仍在运行.

注意2:OSK进程具有Close()方法，但没有任何反应.

因此，KILL方法有效！

Note1: the OSK process has a CloseMainWindow() method, however, it returns true, indicating success, but the OSK remains running.

Note2: the OSK process has a Close() method, but nothing hapens.

So, the KILL method works!
