I'm using BO XI R2.
I want to modify the report.
Following is a code snippet which throws InvalidCastException;
and under that the Message is No Such Interfaces Supported.
Kindly suggest me a solution, if you have been able to crack it.
Also any ideas why such an exception.


using CrystalDecisions.CrystalReports.TemplateEngine;
using CrystalDecisions.ReportAppServer.ClientDoc;
using CrystalDecisions.ReportAppServer.ObjectFactory;
using CrystalDecisions.ReportAppServer.DataDefModel;
using CrystalDecisions.ReportAppServer.Controllers;
using CrystalDecisions.ReportAppServer.CommonObjectModel;
using CrystalDecisions.ReportAppServer.ReportDefModel;
ReportClientDocument reportClientDocument = new ReportClientDocument();

SessionMgr sessionMgr = new SessionMgr();
EnterpriseSession enterpriseSession;
EnterpriseService enterpriseService;
InfoStore infoStore;
InfoObjects infoObjects;
InfoObject infoObject;
ReportAppFactory reportAppFactory;
string sampleReportName;
			
enterpriseSession = sessionMgr.Logon("administrator","","localhost","secEnterprise");
enterpriseService = enterpriseSession.GetService("InfoStore");
infoStore = new InfoStore(enterpriseService);

sampleReportName = "World Sales Report";
infoObjects = infoStore.Query("Select SI_ID From CI_INFOOBJECTS Where SI_NAME='" + sampleReportName + "' And SI_INSTANCE=0");
infoObject = infoObjects[1];

reportAppFactory = (ReportAppFactory)enterpriseSession.GetService("","RASReportFactory").Interface;

reportClientDocument = reportAppFactory.OpenDocument(infoObject.ID,0);



reportClientDocument = reportAppFactory.OpenDocument(infoObject.ID,0);
code segment throws the Exception
