Executing a Command
Some DDE servers can execute commands. These commands are identified by command strings, which can be sent to them within the current conversation.
To send a command to a DDE server, call:
DdeExecute( service, topic, string )
Service and topic identify the conversation as part of which the command is sent. This conversation must have been started with:
DdeConnect( service, topic )
and must not have been finished with:
DdeDisconnect( service, topic )
String is the command to be executed by the server.
