晒个昨天上午在家写的小程序吧 -- 给黑莓内置程序"Task"添加菜单

目标：

1.程序随开机自动启动，给Task添加一个菜单Assign To

2.点击Assign To，从地址簿里面选人

3.对话框提示是否Assign给这个人

4.下一步：通过Web Service访问公司内外的Domino服务器，把这个Task assign给同事。(正在做)

 

 

package lab;
/*
.创建报告
点击assign按钮，如果发现没有保存（只有uid属性），就提示需要保存
   选人进行assign
  提示这个项目已经assgin给谁了，失败；或者是否继续assgin
   提示assign成功
  提示assign失败
