C#調用Windows(8/10)內建的虛擬鍵盤

以下是調用代碼：

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, int wParam, int lParam);[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 bool PostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]private static extern IntPtr FindWindow(string lpClassName, string lpWindowName);[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]private static extern int RegisterWindowMessage(string lpString);  //顯示螢幕小鍵盤public static int ShowInputPanel(){      try      {            dynamic file = "C:\\Program Files\\Common Files\\microsoft shared\\ink\\TabTip.exe";            if (!System.IO.File.Exists(file))                return -1;            Process.Start(file);            //return SetUnDock(); //不知SetUnDock()是什麼，所以直接注釋返回1            return 1;      }      catch (Exception)      {            return 255;      }}//隱藏螢幕小鍵盤public static void HideInputPanel(){      IntPtr TouchhWnd = new IntPtr(0);      TouchhWnd = FindWindow("IPTip_Main_Window", null);      if (TouchhWnd == IntPtr.Zero)            return;      PostMessage(TouchhWnd, WM_SYSCOMMAND, SC_CLOSE, 0);}

 

Windows系統還有一個OSK的虛擬鍵盤，這個是浮動的，和自動彈出的鍵盤有點區別，需要的話也可以直接調用。 

Process.Start(@"C:\windows\system32\osk.exe");
