#define __DDE_H
// Purpose: Header file for DDE remote control
// Comments:
// Revision History:
// 12-27-94 created GAB
// 12-28-94 designed DDE wrapper class with multiple conversations
// in mind, all conversations using the same HSZ
// strings, and a mechanism to find the coversation
// on the fly.
// The conversations are correctly multiplexed via the
// NetscapeDDECallBack function as it can access
// all instances of CDDEWrapper and it has the
// conversation identifier to compare with.
//
// Required Includes
