请问vc控件ComboBox的data内容(汉字)怎么跟数据库中的代码(数字)关联

yctree 2012-01-12 05:17:31
近期做一个小程序,实现几张表的处理,一般来说这样的实例很多,但是数据库设计的字段必须跟给我的标准文档数据库字段大小必须一致,这样就出现一个问题,比如,名族,文档里是2个char,但是写成汉字的时候可能就不止两个汉字了,比如维吾尔族。那就要实现这样的功能,即:ComboBox控件中的data数据有汉族、藏族、维吾尔族等等,access数据库里名族字段是代码比如01表示汉族,02表示藏族,诸如此类,请问,如何实现?有几种实现?比较简单的实现方式是那些?

简单点
分配内存自己建立对应表
用ComboBox zero-based index of the item 和 民族代码、民族名称建立个对应表
定义结构

#define 2 CODE_LEN

strucnt __COBTAB
{
int idx;
code char[CODE_LEN + 1];
nation char[32];
}
//建立链表
vector<__COBTAB> vt;

当在COMBOBOX中选择之后,找回索引,根据索引在vt中找,最终取出名族名称。

方法一:
让你ComboBox对表示民族的字符串索引和数据库中的代码一致,这样,你只需要使用CComboBox::GetCursel()和CComboBox::SetCursel()进行操作即可。
方法二:
建立map<int, string<char>>的一对一索引
