            string MyCompanyName;
            MyCompanyName = myComObj.GetConfigKey("Company").Trim();

            Context context;
            LikeRestrictionOfString companyRestriction;
            CompanyCriteria companyCriteria;

            context = new Context();

            // Set up the context object
            // To retrieve from the system database set the organization key to null
            context.OrganizationKey = null;
            context.CultureName = "en-US";

            // Create a restriction object to query by company ID
            // Query for all possible company ID values

            companyRestriction.Like = MyCompanyName ;

            // Create a company criteria object and add the restriction object
            companyCriteria = new CompanyCriteria();
            companyCriteria.Name = companyRestriction;

            // Retrieve the list of companies
            MyCompany = MyDynamicsGP.GetCompanyList(companyCriteria, context);
            return MyCompany[0].Key.Id ;
