ddeexec

Purpose

Send execution string to DDE server application.

rc = ddeexec(channel,command,item,timeout)

rc: The return code: 0 indicates the function call failed, 1 indicates it succeeded.
channel: The channel assigned to the conversation, returned by ddeinit.
command: A string that specifies the command to be executed.
item: (optional) A string that specifies the DDE item name for execution. This argument is not used for many applications. If your application requires this argument, it provides additional information for command. Consult your server documentation for more information.
timeout: (optional) A scalar that specifies the time-out limit for this operation. timeout is specified in milliseconds (1000 milliseconds = 1 second). The default value of timeout is three seconds.

ddeexec sends a string for execution to another application via an established DDE conversation. Specify the string as the command argument.
