将报告上传到 Business Objects XI 3.1 时，可以使用Database Configuration中央管理控制台中的选项修改报告的默认属性。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。

我正在尝试编写一个 C# .NET Windows 窗体，它将遍历指定文件夹/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？

我已通读 SDK 并找到了 ReportLogon 类……这是我访问数据库配置属性所需的吗？

谢谢。

我正在处理相同的要求。我正在开发一个工具，使用 swing 和 BO SDK 来更新批量 Crystal 报表连接的 .

下面是我将用于更新连接的虚拟代码。

例子：-

     package org.bukhantsov.javatool;

import com.businessobjects.rebean.wi.DocumentInstance;
import com.crystaldecisions.sdk.exception.SDKException;
import com.crystaldecisions.sdk.framework.CrystalEnterprise;
import com.crystaldecisions.sdk.framework.IEnterpriseSession;
import com.crystaldecisions.sdk.framework.ISessionMgr;
import com.crystaldecisions.sdk.occa.infostore.IInfoObject;
import com.crystaldecisions.sdk.occa.infostore.IInfoObjects;
import com.crystaldecisions.sdk.occa.infostore.IInfoStore;
import com.crystaldecisions.sdk.occa.report.application.ReportClientDocument; 
import com.crystaldecisions.sdk.occa.managedreports.reportAppFactory; 
import com.crystaldecisions.sdk.occa.report.application.databaseController;
import com.crystaldecisions.sdk.occa.report.data.IConnectionInfo;
import com.crystaldecisions.sdk.occa.report.document.*;
import com.crystaldecisions.sdk.occa.report.definition.*;
import com.crystaldecisions.sdk.occa.report.lib.propertyBag;

class ChangeDataSource {
    public static void main(String args[]){

       String cms = "134.X.X.X:6400";
       String username = "Administrator";
       String password = "";
       String auth = "secEnterprise";

       IEnterpriseSession enterpriseSession = null;
       ISessionMgr sessionMgr = null;//CrystalEnterprise.getSessionMgr();   
       Exception failure = null;
       boolean loggedIn = true;

       ReportClientDocument clientDoc = null;

       if (enterpriseSession == null)
       {
      try
      {
          sessionMgr = CrystalEnterprise.getSessionMgr();

          enterpriseSession = sessionMgr.logon(username, password, cms, auth);
          System.out.println("\nLOGIN SUCCESSFUL\n");

      }
      catch (Exception error)
      {
          loggedIn = false;
          failure = error;
      }

      if (!loggedIn)
      {

         System.out.println("\nLOGIN FAILED\n");
      }
      else
      {
          // Query for the sample report from the Enterprise CMS.
          try {
            IInfoStore iStore = (IInfoStore) enterpriseSession.getService("InfoStore");
            IInfoObjects infoObjects = iStore.query("Select SI_ID From CI_INFOOBJECTS Where SI_Type='CrystalReport'");

            System.out.println("\ninfoObjects size = "+infoObjects.getResultSize());

            clientDoc = new ReportClientDocument();
            clientDoc = reportAppFactory.openDocument(infoObject,0, java.util.Locale.US);

            switch_tables(clientDoc.getDatabaseController());

         }catch(ReportSDKException re){            
            re.printStackTrace();
         }catch(SDKException re){

    int replaceParams = DBOptions._ignoreCurrentTableQualifiers + DBOptions._doNotVerifyDB;

    // Now replace the connections  
    dbController.replaceConnection(oldConnectionInfo, newConnectionInfo, pFields, replaceParams);

    //Store the report source in session, will be used by the CrystalReportViewer.
    //session.setAttribute("reportSource", boReportClientDocument.getReportSource());

    //Launch CrystalReportViewer page that contains the report viewer.
    //response.sendRedirect("CrystalReportViewer.jsp");

   }

 }

希望这会帮助你。

谢谢，萨钦
