如何从c＃关闭TabTip虚拟键盘 [英] How to close TabTip virtual keyboard from c#

问题描述

我在我的wpf应用程序中使用TabTip.exe作为虚拟键盘。当我试图杀死进程时，它不会被杀死并抛出异常"Access is Denied"。

I am using TabTip.exe as virtual keyboard in my wpf application. When I am trying to kill the process it's not getting killed and throwing exception "Access is Denied".

TabTip版本是10.0.16299.64，我认为是较新的版本。以前版本的TabTip在下面的代码中工作正常。

TabTip version is 10.0.16299.64, which I think is the newer version. The previous version of TabTip was working fine with the code below.

Process [] tabtip = Process.GetProcessesByName（" TabTip"）;

Process[] tabtip = Process.GetProcessesByName("TabTip");

if（null！= tabtip）

{

        tabtip.ToList（）。ForEach（a => {if（null！= a）{a.Kill（）;}}）;

}

if (null != tabtip)
{
       tabtip.ToList().ForEach(a => { if (null != a) { a.Kill(); } });
}

即使我发现了一件事。如果TabTip已打开，并且从任务管理器我选择该过程并单击"结束进程"，那么它也不会被关闭。关闭TabTip的唯一方法是单击其上的关闭按钮。

Even I observed one thing. If TabTip is open and from Task Manager I am selecting the process and clicking "End Process", then also it's not getting closed. The only way to close the TabTip is to click the close button present on it.

如果您想通过代码关闭TabTip.exe，可以查看以下代码：

If you want to close TabTip.exe by code, you can take a look the following code:

 private Process _p = null;
        private void btn2_Click(object sender, RoutedEventArgs e)
        {
          _p= Process.Start(@"C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe");
            //_p = Process.Start("osk.exe");
        }
        private void btn3_Click(object sender, RoutedEventArgs e)
        {
          if(_p!=null)
            {
                _p.Kill();
                _p.Dispose();
                _p = null;
            }
               
            
        }

最好的问候，
