return k.Text1;
else
return null;
}
void KeyText_MouseDoubleClick(object sender, MouseEventArgs e)
{

}
private void KeyBtn_Click(object sender, EventArgs e)
{
this.showKeypad();

{
Process process = new Process();
process.StartInfo.UseShellExecute = false;

process.StartInfo.FileName = "c:\\Windows\\system32\\osk.exe";
process.StartInfo.Arguments = "";
process.StartInfo.WorkingDirectory = "c:\\";
process.Start(); // Start Onscreen Keyboard
process.WaitForInputIdle();
Win32.SetWindowPos((int)process.MainWindowHandle,
Win32.HWND_BOTTOM,
300, 300, 1200, 600,
Win32.SWP_SHOWWINDOW | Win32.SWP_NOZORDER);
}
}
}
这工作得很好我有一个很好的键盘（好尺寸触摸屏），但是，我不熟悉C＃和VB在所有....改变文中根据触摸屏键盘I显示一个文本框。
This works just fine I have a nice keypad (good size for a touch screen), However, i am not familiar with C# and VB at all.... change the Text in a textbox according to the touch screen keyboard I show.
谢谢，
推荐答案
要创建自己的屏幕键盘上，你基本上需要做到以下几点。
To create your own on screen keyboard you basically need to do the following.
1 - 创建一个Windows键盘应用程序，您可以用交互但不从当前控件偷输入焦点，其中每个应用程序你在哪里目前的工作。
1- Create a windows keyboard application that you can interact with but does not steal the input focus from the current control in which every application you where currently working.
2-键盘应用程序应该发送按键当前激活的控制响应点击在键盘的应用程序按钮。
2- The keyboard application should send key presses to the currently active control in response to clicking of buttons in the keyboard application.
我以前提供的以下的答案提供了如何做到这一点使用的WinForms一个简单的演示。
The following answer I provided previously provides a simple demonstration of how to do this using WinForms.
基本上与
Basically the window is created with the WS_EX_NOACTIVATE style, which prevents the window from becomming active and steeling input focus. Then in response to button clicks it uses SendKeys to send the approriate key press message to the control that has input focus.
以下的答案必须说明如何应用的 WS_EX_NOACTIVATE 风格WPF应用程序。
The following answer shows how to apply the WS_EX_NOACTIVATE style to a WPF application.
有比WS_EX_NOACTIVATE其他其他解决方案，但是这是简单和角落找寻拖动窗口时只从一个次要表象的毛刺缺点。它与可以克服一些聪明的消息处理。
There are other solutions other than WS_EX_NOACTIVATE, but this is simple and only suffers from a minor presentational glitch when dragging the window arround. Which with some clever message processing can be overcome.
