How To Add CommandTable at Runtime

Question

Hi there ,
I am using Crystal Reports 12 with Visual Studio.NET 2008 and SQL Server 2005 as my Database engine , I have used the RCAPI ( Report Creation API for .NET SDK ) which can be used to create reports at runtime but i have failed to complete my task as described below :
1-I Have Created a CommandTable with the following command
       CommandTable myTable=new  CommandTable();
2- Then i Have configured the CommandTable object as follows :
          //Creating A ConnectionInfo Object to be set to the CommandTable.ConnectionInfo
            ConnectionInfo info=new ConnectionInfo();
            info.Password = "pw";
            infol.UserName="sa";
            info.Attributes.Add("QE_DatabaseName", "Northwind");
            info.Attributes.Add("QE_DatabaseType", "OLE DB (ADO)");
           info.Attributes.Add("QE_ServerDescription","OT-DEVSERVER-1
SQLSRV2005");
            info.Attributes.Add("QE_SQLDB","1");
            info.Attributes.Add("SSO Enabled", "0");
            info.Kind = CrConnectionInfoKindEnum.crConnectionInfoKindCRQE;
            myTable.ConnectionInfo=info;
            myTable.Name = "Products";
            myTable.Description = "Products of the Northwind DB";
            myTable.Alias = "Products";
            myTable.CommandText = "Select * From Products";
3- The Problem is Coming Now .......
when i try to add the commandTable to the report as follows :
            ReportClientDocument.DatabaseController.AddTable(myTable, null);
i Got The following Error :
*Logon failed.*
*Error in File Northwind_ListReportTemplate {436793F2-F1FA-4CC2-8251-BC92683830A1}.rpt:*
*Unable to connect: incorrect log on parameters*
any Help How could i add this table at runtime .
Thanks,
Ahmed

Hi Vivek,
Try this,
if(firstTime)
     IWDTransparentContainer tc=(IWDTransparentContainer)view1.getElement("RootUIElementContainer");
     IWDNodeInfo tableNodeInfo1_Source=wdContext.getNodeInfo().addChild("TableNode1_Source",null,true,false,true,false,true,true,null,null,null);
     IWDTable tab1=(IWDTable)view1.createElement(IWDTable.class,"FirstTable");
     tc.addChild(tab1);     
     tab1.setWidth("100%");
     tab1.setGridMode(WDTableGridMode.BOTH);
     tab1.bindDataSource(tableNodeInfo1_Source);
     IWDAttributeInfo name=tableNodeInfo1_Source.addAttribute("Name","ddic:com.sap.dictionary.string");
     IWDAttributeInfo age=tableNodeInfo1_Source.addAttribute("Age","com.sap.dictionary.string");
     IWDTableColumn nameCols=(IWDTableColumn)view.createElement(IWDTableColumn.class,"nameCol");
     IWDCaption c1=(IWDCaption)view.createElement(IWDCaption.class,"nameCap");
     c1.setText("Name");
     nameCols.setHeader(c1);
     IWDTextView nameView=(IWDTextView)view.createElement(IWDTextView.class,"nameView");
     nameView.bindText(name);
     areaCols1.setTableCellEditor(nameView);
     tab1.addColumn(nameCols);
     Similarly for Age
