Re: Unable to cast COM object of type 'System.__ComObject' to interface type

Hi Ketan,

I saw two sintax errors in your code.

Change the line:

SAPbobsCOM.ReportTypesService rptTypeService = (SAPbobsCOM.ReportTypesService)(oCompany.GetCompanyService().GetBusinessService(SAPbobsCOM.ServiceTypes.ReportLayoutsService));

by:

SAPbobsCOM.ReportTypesService rptTypeService = (SAPbobsCOM.ReportTypesService)(oCompany.GetCompanyService().GetBusinessService(SAPbobsCOM.ServiceTypes.ReportTypesService));

And, change the line:

SAPbobsCOM.BlobParams oBlobParams = (SAPbobsCOM.BlobParams)(oCompany.GetCompanyService().GetBusinessService(SAPbobsCOM.ServiceTypes.ReportLayoutsService));

by:

SAPbobsCOM.BlobParams oBlobParams = (SAPbobsCOM.BlobParams)(oCompany.GetCompanyService().GetDataInterface(SAPbobsCOM.CompanyServiceDataInterfaces.csdiBlobParams));

Hope it helps,

Regards,

Diego
