用VS2008，C#在WINCE6.0，软键盘显示隐藏方法

        /// <summary> 
        /// 显示/隐藏 软键盘 方法1      
        /// </summary>
        ///
        public static InputPanel _softKeyBoard = new InputPanel();

        public static void ShowHideSoftKeyBoard(Boolean isShow)
        {
            _softKeyBoard.Enabled = isShow;
        }

        /// <summary>
        /// 显示/隐藏 软键盘 方法2      
        /// </summary>
        /// <param name="isShow"></param>
        /// <returns></returns>
        ///
        [DllImport("coredll", EntryPoint = "SipShowIM")]
        private static extern bool SipShowIM(IntPtr SIP_STATUS);
        private static readonly IntPtr SIPF_OFF = (IntPtr)0x0;
        private static readonly IntPtr SIPF_ON = (IntPtr)0x1;

        public static bool SipShowIM(bool isShow)
        {
            return SipShowIM(isShow ? SIPF_ON : SIPF_OFF);
        }

例如在tbSend输入获取焦点时，显示软键盘，逝去焦点时隐私软键盘，方法

        private void tbSend_LostFocus(object sender, EventArgs e)
        {
            Common.SipShowIM(false);
        }

        private void tbSend_GotFocus(object sender, EventArgs e)
        {
            Common.SipShowIM(true);
        }
