就红色的这点我用的是C++和SQL Server但是红色这部分的功能没有实现为什么。就是设置宽度和UserName 被用户名,UserPwd A被密码代替

实现将“用户名”代替UserName “密码”代替UserPwd

实现宽度的调整
在C++中我用ADO中的ADO Data来连接我的数据库,DataGrid来显示我在数据库中的表
因为我数据库中的那张表的字段是UserId UserName UserPwd所以我想将它改为用户名 密码
并将第一个UserId给删去 ,大概就这个意思,但是不能实现
DataGrid 中已经显示出表了,我加红色的这段程序只是为了实现将字段是UserId UserName UserPwd
替换成用户名 密码
大概就是这个意思,不知道我说清楚没
有个建议,如果是使用的MS SQL 2000/2005,为什么不写成过程,这样调用起来就简单多了,
写在程序里有点多,个人建议。
