Sending message to another app

Hi all. Just a simple query for a newbie. I have written a simple app
to send a message to another app using SendMessage and PostMessage. It
works fine.

I want to know how I would now need to change my code to send the same
messages to another computer over a simple LAN. Is this even possible ?

Both boxes are running Win98.

Not with Windows messages. You can use NetDDE or DCOM (I would advise you to
use DCOM).

ps. See http://www.techvanguards.com for information on COM and Delphi.

Re:Sending message to another app

Thank You very much for your help.

I have been putting off going too deeply into COM as Im still getting my head
around the language, but I guess now is the time.

"Ah well, the honeymoon had to end sometime".... actually, my preliminary
reading shows it might not be as difficult as I first feared.... go figure...

Re:Sending message to another app

I did a work around on this between lanbased apps.
The app that sends a msg sends the code as a text file. In my case I used
the TInifile to write the messages.
The app that receives the msgs has a timer that checks the changes in the
inifile and fetches any new msg written in it.
So far it is working...
Hope this helps.
