Summary

Package

win32

Signature

Arguments

name

A symbol.

service

A string.

class

A subclass of dde-client-conversation .

Values

name

A symbol.

Description

The macro define-dde-client defines a mapping from the symbol name to the DDE service name with which to establish a conversation, and the conversation class to use for this conversation. The argument service is a string which names the DDE service. It defaults to the print-name of name . The argument class is a subclass of dde-client-conversation which is used for all conversations with this service. It defaults to dde-client-conversation . Specifying a subclass allows various aspects of the behavior of the conversation to be specialized.

Note that it is generally not necessary to register client services unless a specialized conversation type is required. However, it is sometimes convenient to register a client service in order to allow the service name to be changed in the future.

If the macro executes successfully, the name of the DDE service is returned.
