c#调用windows的虚拟键盘

c#调用windows自带的tabtip.exe来调用虚拟键盘

  dynamic file = "C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe"; if (!System.IO.File.Exists(file)) return;
    Process.Start(file);

关闭虚拟键盘

private const Int32 WM_SYSCOMMAND = 274; private const UInt32 SC_CLOSE = 61536;
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] private static extern bool PostMessage(IntPtr hWnd, int Msg, uint wParam, uint lParam);
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] private static extern IntPtr FindWindow(string lpClassName, string lpWindowName); private void textBox_LostFocus(object sender, RoutedEventArgs e)
{
    IntPtr TouchhWnd = new IntPtr(0);
    TouchhWnd = FindWindow("IPTip_Main_Window", null); if (TouchhWnd == IntPtr.Zero) return;
    PostMessage(TouchhWnd, WM_SYSCOMMAND, SC_CLOSE, 0);
}

c#调用Windows系统的OSK虚拟键盘

Process.Start(@"C:windowssystem32osk.exe");
