        }
        public zkemkeeper.CZKEMClass axCZKEM1 = new zkemkeeper.CZKEMClass();
        private bool bIsConnected = false;//the boolean value identifies 
whether the device is connected
        private int iMachineNumber = 1;//the serial number of the device.
After connecting the device ,this value will be changed.
        TENTERTableAdapter tenteradapter = new TENTERTableAdapter();
        T012_GATETableAdapter gateadapter = new T012_GATETableAdapter();
    }
}

Answer: click on the reference you have, I think for that specific project
that would be ‘zkemkeeper’ then on its properties just set the ‘Embed Interop Type’
to ‘False’ I hope this would help.
