[智能设备]SmartPhone开发常用类（二） 改变输入法

          const uint EM_SETINPUTMODE = 0x00DE;

          const int GW_CHILD = 5;

          const uint LB_SETCURSEL = 0x0186;

  
          public static void SetInputMode(Control ctrl, InputMode mode) 
          {
               ctrl.Capture = true;
               IntPtr h = GetCapture();
               ctrl.Capture = false;

               IntPtr hEditbox = GetWindow(h, GW_CHILD);
               SendMessage(hEditbox, EM_SETINPUTMODE, 0, (uint)mode);
          }
          public enum InputMode 
          {
               EIM_SPELL = 0,//英文
               EIM_AMBIG = 1,//拼音
               EIM_NUMBERS = 2,//数字
               EIM_TEXT = 3,//拼音
          }

      }
}

要注意的是 OpenNETCF.org的工具包的WindowsCE.Forms以及Microsoft.WindowsCE.Forms,都只能用于Poacket PC 2003和Windows Mobile 5.0，其他版本的操作系统必须按照上述写法来书写代码才能调试通过
