如何在Business Objects XI 3.1中修改Crystal Report的數據庫配置屬性？

Question

將報表上載到Business Objects XI 3.1時，可以使用中央管理控制檯中的Database Configuration選項修改報表的默認屬性。在此選項中，您可以選擇使用報表中使用的數據源信息或指定自定義數據源。

我正在嘗試編寫一個C＃.NET Windows窗體，它將遍歷指定文件夾/子文件夾中的所有報告並更改默認的用戶ID和密碼。這可能嗎？如果是這樣，請有人提供一個例子嗎？

我已經通過SDK讀過，我發現了ReportLogon類...這是我需要訪問數據庫配置屬性嗎？

謝謝。

我工作的是同樣的要求。我正在開發一個工具，通過使用swing和BO SDK來更新批量Crystal報表連接。

下面是我將用於更新連接的虛擬代碼。

例子： -
