 4'********************************   
 5'功能:从Application中提取数组,如果application中的数据为empty值的时候再调用wawa_Get_Rows()函数来给application赋值.   
 6' ,你可以在修改数据库的时候把相应的application值清空成empty,这就浏览的时候就会自动更新application了   
 7' 如果你更新了数据库(比如说添加,修改或者删除了数据)那么在修改数据库后把相应的application变量去掉,   
 8' 用下面的一条语句来实现清空指定的application值,其中strapp参数是要去掉的application变量名   
 9' application.Contents.Remove(strapp)
