调用Server2012虚拟键盘 [英] Calling Server2012 virutal keyboard

问题描述

亲爱的

在Windows Server 2012下运行的一种应用程序中，我需要在触摸文本框时调用虚拟键盘，并在出现焦点丢失时将其隐藏.

In one of application running under Windows server 2012, I need to call the virual keyboard when a text box is touch and hide it when lost focus occurs.

除此之外，我需要确保虚拟键盘根据所关注的控件正确放置.

In addition to that, I need to be sure the virtual keyboard is properly position based on the control which gets focus on.

基于此，我有2个问题:

based on that I have 2 questions :

1-在控制焦点上有效显示/隐藏此kb的方法是什么?理想情况下，我应该从原始控件中实现一个新的tetx控件，但该控件可以实现VKB处理

1 - What is the way to show/hide this kb efficient on control focus? Ideally I would implement an new tetx control from original control but which implement VKB handling

2- kb定位是否自然取决于要控制的文本框的处理，还是需要以编程方式移动它，这可能会很奇怪?

2- Does the kb positioning is nativly handle depending on text box which gets control or it is needed to move it programmatically which could be wierd ?

您可以通过启动osk.exe显示虚拟键盘.然后，当TextBox失去焦点时，您可以终止该过程.像这样:

You could display the virtual keyboard by starting the osk.exe. You could then kill the process when the TextBox loses focus. Something like this:

        <TextBox GotKeyboardFocus="TextBox_GotKeyboardFocus" LostKeyboardFocus="TextBox_LostKeyboardFocus" />

        private void TextBox_GotKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
        {

            System.Diagnostics.Process.Start("osk.exe"); // display virtual keyboard

        }

        private void TextBox_LostKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
        {
            System.Diagnostics.Process p = System.Diagnostics.Process.GetProcessesByName("osk").FirstOrDefault();
            if (p != null)
                p.Kill();
        }

这里的WPF可能只会帮助您开发虚拟键盘的UI，我们不熟悉系统级别的注册步骤.

WPF here may only help you develop the UI of your virtual keyboard, we are not familiar with the system level register step.

最好的问候，
