我如何正确地关闭从C＃WinForm的屏幕上的键盘的过程？ [英] How do I close the on-screen keyboard process from C# winform correctly?

问题描述

我目前正在设计一个图像浏览器，允许用户输入她的电子邮件和数字得到的图像。这困扰我的部分是让屏幕上的键盘关闭。我使用这段代码，启动Windows进程：

 字符串progFiles = @C：\Program Files\Common Files\Microsoft Shared\ink; 
串keyboardPath = Path.Combine（progFilesTabTip.exe）; 
过程keyboardProc =的Process.Start（keyboardPath）; 
  

在这之后我打开一个VB输入框，为电子邮件地址提示（我用的屏幕上的键盘，因为应用程序将显示在触摸屏上）。后此提示我要自动关闭过程

我试着用下面的关闭过程：

  keyboardProc.Kill（）; 
 keyboardProc.Dispose（）; 
 keyboardProc.Close（）; 
 keyboardProc = NULL; 
  

他们没有工作，只是抛出异常：

 'System.InvalidOperationException'类型的未处理的异常出现在System.dll中
附加信息：因为进程已退出无法处理请求。 
  

我也试图通过ID识别过程，并关闭它这样，也不能工作。
我也看了一下：
的 C＃/。NET：关闭外面主窗口
另一个进程，但没有得到它要么工作..：（

我敢新的C＃，这是我第一次从代码中调用Windows进程？ - 我失去的东西。

非常感谢你提前

解决方案

U可以这样做：

 工艺过程=新工艺（）; 
 
 process.StartInfo.FileName = progFiles; //文件名
的Process.Start（）; 
 process.Close（）; 
  

I'm currently designing an image viewer that allows the user to input her e-mail and get the images digitally. The part that troubles me is getting the on-screen keyboard to close. I use this piece of code to start the windows process:

string progFiles = @"C:\Program Files\Common Files\Microsoft Shared\ink";
string keyboardPath = Path.Combine(progFiles, "TabTip.exe");
Process keyboardProc = Process.Start(keyboardPath);

After which i open a VB InputBox to prompt for the e-mail address (for which i use the on-screen keyboard, since the application will be shown on a touch screen). After this prompt I want to close the process automatically.

I've tried to close the process with the following:

keyboardProc.Kill();
keyboardProc.Dispose();
keyboardProc.Close();
keyboardProc = null;

None of them works and simply throws the exception:

An unhandled exception of type 'System.InvalidOperationException' occurred in System.dll
Additional information: Cannot process request because the process has exited.

I also tried identifying the process by ID and closing it this way, didn't work either. I also had a look at: C#/.NET: Closing another process outside the main window but didn't get it working either.. :(

I'm pretty new to C# and this is the first time I've invoked a windows process from code - am I missing something?

Thank you very much in advance!

解决方案

u can do:

            Process process = new Process();

            process.StartInfo.FileName = progFiles;//Filename
            process.Start();
            process.Close();
