Summary
Network DDE is a technology that allows applications that use the DDEtransport to transparently exchange data over a network. It consistsof two major components:

  1. The NetDDE agent. This is a service that acts as a proxy for the remote DDE application. It communicates with all local DDE applications, and with remote NetDDE agents using NetBIOS as shown in this chart:
         Machine A                                        Machine B   +-----------+                                   +-----------+   |           |                                   |           |   | DDE App 1 |                                   | DDE App 2 |   |           |                                   |           |   +-----------+                                   +-----------+           ^ |                                        ^ |           | |                                        | |           | |                                        | |           | |                                        | |           DDE                                        DDE       Conversation                               Conversation           | |                                        | |           | |                                        | |           | V                                        | V        +------+                                   +------+        |NetDDE|                                   |NetDDE|        | Agent| < ------ NetBIOS session ------ > | Agent|        +------+                                   +------+
  2. A DLL that implements NetDDE API functions such as NDdeShareAdd, NDdeShareDel, and so on. This DLL is usually named NDDEAPI.DLL.
In the interests of backwards compatibility, Windows 95 includes a NetDDEagent and a 16-bit NetDDE API DLL. However, Windows 95 does not include a32-bit NetDDE API DLL. Consequently, 32-bit applications that use NetDDEAPI functions will need to thunk to the 16-bit NETAPI.DLL.
