Borland c++ builder with database

[robber88]

Hello all in this group!

I am newbie of BCB4.0, I hope someone can help me here.

I have a from named frmMain, would like to call a DLL, this DLL is used for get data(s) from a Table, and show the data(s) in edit box on frmMain.

How do I add the datasource and table components in a DLL (DLL do not have a form so I cannot use visual method to add them)...

Please advise me how do I write code to define my existing table, then let me to get data from my existing table?

朋友，虽然在DLL中不便包含FORM（根据你的需求也不需要包含FORM），做一个函数，使其返回TDATASOURCE类型的结果，然后通过手工将TDBEditBox的DataSource属性与其相连即可。

在DLL 为什么不能用FORM呢？如果不想用FORM就象alexela 说的那样用个
数据模块也可以。因为这样可以可视化编辑它， 比较方便。
不过，因为是DLL， 必须通过定义导出的函数 创建FORM或数据模块的类实例。

就算不用这些也行啊。
定义这些类的几个全局指针变量，直接在几个函数里创建这些对象，设置它们的属性，
设置它们的事件，尽管不能可视化，不过还是很容易。
