/*
|
|
* Mini-DDE implementation
|
|
|
|
Most transactions involve a topic name and an item name (choose these
|
|
as befits your application).
|
|
|
|
A client can:
|
|
|
|
- ask the server to execute commands (data) associated with a topic
|
|
- request data from server by topic and item
|
|
- poke data into the server
|
|
- ask the server to start an advice loop on topic/item
|
|
- ask the server to stop an advice loop
|
|
|
|
A server can:
|
|
|
|
- respond to execute, request, poke and advice start/stop
|
|
- send advise data to client
|
|
|
|
Note that this limits the server in the ways it can send data to the
|
|
client, i.e. it can't send unsolicited information.
