tk2dde {tcltk2}

Use DDE (Dynamic Data Exchange) under Windows

Description

These functions are Windows-specific. They issue an error under a different platform.

Usage

tk2dde(topic = NULL)
tk2dde.services(service = "", topic = "")
tk2dde.exec(service, topic, command, async = FALSE)
tk2dde.poke(service, topic, item, data)
tk2dde.request(service, topic, item, binary = FALSE)

Arguments

topic

the 'topic' to reach or expose. A DDE server is accessed as 'service'|'topic'. In the case of tk2DDE(), a non null topic activates the DDE server, and a null topic deactivate it.

service

the name of the service to reach. In tk2DDEservices, if both service and topic are empty, the list of all available DDE service is returned, otherwise, only available topics for a given service are listed.

command

a string with the command to run in the external application (syntax depends on the server).

async

is a command run asynchroneously (returns immediately, before the command is processed), or not?

item

the concerned item (usually a variable name, a range in a worksheet, etc...).

data

the new value for the item.

binary

should the return bez treated as binary data or not?
