Hi,

I'm looking for a solution with which I can let two Windev Applications
communicate with each other.
I was hoping to solve this issue using the DDE functions Windev has
implemented.

I just don't seem to be able to establish a connection between the two.

With DDEstart I can run the other Program but I don't know how the
servername has to be defined in the DDEconnect().

Programm1: DDEreceiver
Programm2: DDEserver

Programm1 should access the server with the DDEConnect.
Has someone got a solution either with DDE or other forms of communication.

thank you for the fast response. Since my french is limited I hope I
understood what you suggested (and also will reply in english).
What I'm trying to do is split the monitoring of a technical plant from
the visualisation.
The monitoring will run as a Windows service.

Since there will be quite an amount of information sent back and forth I
need a memory based soultion. Text and Database communication might be
to slow.

Socket could work. Just thought it might be better to split the internal
communication (service <-> visualiaston application) from the external
communication (service <-> plant).
