Dataexchange

> How can I exchenge messages between two app > and how can I recive masseges in my app If all of the applications are on the same machine - OLE, COM, DDE, wm_CopyData, did I missed something? I've seen excellent examples for the wm_copydata at http://www.ixpres.com/epic/delphi/ --- For sending messages between different machines you can use DCOM, TCP/IP, IPX or any other data exchange protocol installed on the machines. Look at the DSP and Torry's too for any components about TCP/IP. I've seen some freeware components on Piette Fran_ois pages too - http://www.rtfm.be/fpiette/indexuk.htm
