Question

将报表上载到Business Objects XI 3.1时，可以使用中央管理控制台中的Database Configuration选项修改报表的默认属性。在此选项中，您可以选择使用报告中使用的数据源信息或指定自定义数据源。

我试图编写一个C＃.NET Windows窗体，它将迭代指定文件夹/子文件夹中的所有报告，并更改默认用户ID和密码。这可能吗？如果是这样，有人可以提供一个例子吗？

我已经阅读了SDK并找到了ReportLogon类...这是我访问数据库配置属性所需要的吗？

感谢。

我正在研究同样的要求。我正在开发一个使用swing和BO SDK来更新批量Crystal报表连接的工具。

下面是我将用于更新连接的虚拟代码。
