SUMMARY
Network DDE is a technology that allows applications that use the DDE transport to transparently exchange data over a network. It consists of two major components:

  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| +--+                                  +--+  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 NetDDE agent and a 16-bit NetDDE API DLL. However, Windows 95 does not include a 32-bit NetDDE API DLL. Consequently, 32-bit applications that use NetDDE API functions will need to thunk to the 16-bit NETAPI.DLL.
