1. Passing Information Between Euphoria Programs
Is there an easy way to pass information between 2 running euphoria programs?
I was thinking of passing the content of a sequence (that could contain huge
amounts of information) from one Eu program to another.
Or atleast, the program starts another eu program - and passes this information
to it, in which case I was thinking of using the function (can't remember
the name of it) that catches parameters.

Yes there is! The process is called DDE or Dynamic Data Exchange.
Thomas Parslow wrote a library called "Interprocess Communication"
that uses Microsofts DDE routines. It's in the Archive.

You might also want to look into "Share Memory Between Processes" by
Mario Steele and Jason Mirwald. It doesn't use DDE but accomplishes a
similar effect. It's in the Archive.
There's also a "Euphoria Data Sharing Demo" by Jordah Ferguson. That's
in the Archive, too. There's a lot of stuff in the Archive.

That routine is called command_line(). Here's a link:

Hi there,
You could also use the WM_COPYDATA message to send info to another
program if that program processes messages. This turns out to
be the simplest of all except...
If your program only needs a small amount of info at startup,
you can use the command line arguments which is even simpler.
Take care,
Al
And, good luck with your Euphoria programming!

Dear ZNorQ
A simple way to pass information between 2 Eu programs if speed is
not an issue is to use textfiles. And Textfile.e in the archive with
its easy to use functions:
save_text_file(sequence fname,sequence text); and
load_text_file(sequence fname)
is just fine for that.

Hi ZNorq,
Yet another way to pass information betwen 2 programs is via clipboard using
private format (see CF_PRIVATEFIST,CF_PRIVATELAST constants)

I can think of a few ;
-temp files using BGET or an EDS database to save the sequence nesting
-whatever Display server uses
- Win Sockets,
- Matt's EUCOM (tricky)
- Matt's ODBC - create a small MDB table to insert messages,
have the recieving app pull and delete from the top
rows so you have a persistant message queue.
- that shared memory lib

Yes I know about DDE, but that means I'll have to include already written
code to make it function. I was just wondering if there was an easy way
to pass along information between programs in native Euphoria. I'll check
out the archives and look for anything that can help me out. Thanks! :D

Hehe, yes I do know about the archive, but it's not always easy to know what
to look for when you're a noob. :D Thanks though, I'll check it out!

Well, the information could be anything of very little- to massive amounts.
I'm not sure how you would use WM_COPYDATA. I'm not too familiar with
Win32Lib's (I recon thats what your referring to) inner workings, but
I'm working on it - and in time getting there too I hope. :P
What I was hoping for was that passing information between programs in
native Euphoria - where there where no need to learn a bunch of include
files - like Win32Lib - NOW.. :D
PS! I'm a steady user of Win32Lib, but that is limited to making forms,
controls, and handlers for now.

Yes, I've been thinking about that, but I'd rather it be transferred without
having to be saved in a file first. Thanks for your thougths though.

Interesting thougth! Not that I like the idea of using clipboard in this way,
but I do have very much need for the clipboard function, and I'm striving
hard to find a solution. You have any reference where I can get more info
on how to use it? (I recon that's related to Win32Lib?)
PS! Reason that I don't like using clipboard for transferring data between
programs is that I use clipboard ALOT at work, and I don't want programs
to mess it up when I'm doing my work. I work alot with databases, xls etc.
to validate data.

Hi ZNorq,
What about pipes or mailslot. It's simple to use it's like reading and
writing to files (same API functions) look at watch-svr I posted lately to
euphoria site. it use a mailslot. The client open the mailslot like it open
a file and write to it. And mailslot can work over LAN. Mailslot are one way
communication but on can use 2 mailslots to communicate both way.
