System.Runtime.InteropServices.COMException (0xFFFFFF96): You are not connected to a company

My code is as follows,

            oComp = new SAPbobsCOM.Company();

            oComp.Server = DbServer;

            oComp.CompanyDB = "APHS_CONSOLE_LIVE";

            oComp.DbUserName = "****";

            oComp.DbPassword = "****";

            oComp.UserName = "*****";

            oComp.Password = "******";

             oComp.DbServerType = SAPbobsCOM.BoDataServerTypes.dst_MSSQL2012;

            //oComp.UseTrusted = true;

            oComp.LicenseServer = "localhost:30000";

            oComp.UseTrusted = false;

            int temp=-1;

            try{

           temp= oComp.Connect();

            SAPbobsCOM.BoObjectTypes obj=new SAPbobsCOM.BoObjectTypes();

            SAPbobsCOM.BusinessPartners oCustomer = oComp.GetBusinessObject(obj);   (Line 153)

           oCustomer = oComp.GetBusinessObject(obj);

           oCustomer.CardCode="8881212";

           oCustomer.CardName = "Chaitanya";

           oCustomer.Add();

            }

            catch(Exception e)

            {

                string error = oComp.GetLastErrorDescription();

                xml = finalOutput(temp + " - " + e.ToString() + " - " + error);

                return xml;

            }

Error  :-

-111 - System.Runtime.InteropServices.COMException (0xFFFFFF96): You are not connected to a company at SAPbobsCOM.ICompany.GetBusinessObject(BoObjectTypes Object) at InformaticaWorkflow.Service.Create() in E:\TIS_WebService\AsianPaints\Production\InformaticaWorkflow\InformaticaWorkflow\InformaticaWorkflow\Service.asmx.cs:line153 - Unable to access SBO-Common database

here,

1) -111 is integer returned by oComp.Connect();

2) Unable to access SBO-Common database , is returned byoComp.GetLastErrorDescription();

Here, if i comment the code for adding BP in B1 and keep just connection code to connect to B1 , then i am able to connect successfully.
