I tried adding the SendData procedure to my class definition, but it is not found when making this call:

oxServer.SendData(tcACK)

Part of the class definition:

**********************************************************
DEFINE CLASS EMPS_Class AS SESSION OLEPUBLIC

	IMPLEMENTS DMSWinsockControlEvents IN "c:\windows\system32\mswinsck.ocx"

	oSock = NULL

	Handler = NULL


	**********************************************************
	PROCEDURE DMSWinsockControlEvents_SendData(Acknowledgement) AS VOID HELPSTRING ""
		* add user code here

		* THIS.oSock.SENDDATA( Acknowledgement )

	ENDPROC

And the beginning of the oxServer subclass definition:

**********************************************************
DEFINE CLASS EMPS_Server_Class AS EMPS_Class
