I like the idea in general, and I like your program. Nevertheless,
*for me* it has ATM no practical advantage over the console window.
For my needs, the most important improvement would be, to make the text
inside the window scrollable, so that your server can show much more
lines than currently (say 500 -- but I think, Windows allows even more).
Secondly, displaying the text in a non-proportional font (such as
"Courier New") is IMHO more versatile, than using a proportional font.
In a non-proportional font, also tables and ASCII art will be shown
correctly. Just try
include connect.ew
ServerPrint(" |\\ _,,,---,,_")
ServerPrint(" /,`.-'`' -. ;-;;,_")
ServerPrint(" |,4- ) )-,_..;\\ ( `'-'")
ServerPrint("'---''(_/--' `-'\\_)")
and see, what currently happens to the kitty.
An advanced option also could be, that the user can choose a font. 
*If* your DisplayServer should act as replacement for the console window,
IMHO it should show the output of an Eu program in a similar way,
especially
- don't start with a new line after each call
- interpret the "\n" as "newline" character.
Also a button for clearing the window would be useful.
You see, there is always room for improvement.
Best regards,
Juergen

You can do that with the Eu-mirc bot code, using mirc to select any font at
any time you wish. Changing a window font redraws the screen. I have used
mirc as a Eu display. Al's Eu code is good too, for what it does. Mirc 6.03
can load up literally 100's of fonts, i use it for Chinese, Russian, and
Japanese, but it has more: Korean, Thai, etc..

I've put up a little program using Thomas Parslow's ipc handler, which
is still in proof-of-concept stage. Can someone test it on XP?
The url is http://palacebuilders.pwp.blueyonder.co.uk/euphoria.html
It is the last item on that page.
Originally I wrote this for an entirely different purpose.
The files are:
run.exw - similar-ish to the display server, it runs in the
background. If you run this, it starts up test.exw automatically.
test.exw - a test program. If you run this it will automatically load
run.exw if it is not already running (there is a lost focus bug - tho
I'm sure that can be fixed fairly easily).
test2.exw is a tiny message_box example.
Pressing Run should fire up the message box, closing that should post
a message back to the calling program and display it. It is not at
this stage supposed to look anything like Display Server.
If (*IF*) it works on XP, it would have some advantages over Al Getz's
Display Server: it is written entirely in Euphoria, so it would be
easy for someone to make it scrollable, change the font, add a clear
button, etc, and it is not necessary to remember to fire up the
display server beforehand. Maybe someone would like to tidy it up? It
needs a complete rewrite really, but hey, it's only 300 lines of code.
The demo uses win32lib, but I don't think it would be too hard to make
it cross-lib.

I think a clear source Eu program would be best for this task (so that it would
be portable and easily modified for new versions of Windows, and users could
add other desired features, etc.) Using mIRC for this task would be overkill
IMHO.

I thought you were taking the mick. What you describe is both programs
crashing. It needs debugging on XP, so not much I can do anyway.

8. Re: Al Getz Display Server
It appears that you are using a file name, or path, for something in
there. The IPC call uses Shared Memory. Somehow, the path you are giving is
used as the name of the shared segment of memory. This is not allowed. I'm
not familiar with the IPC include, but you will have to change some
parameter so that it does not use any backslashes. Backslashes aren't
supposed to be allowed on Win 9x/ME either.

I didn't know that. I've removed the path and put a revised version up
I also cured the focus bug.

LOL. Actually it is just a bit of code I wrote last year, for an
entirely different reason (so I could exec a program from MEditor
without waiting for a result code, and hence preventing any further
edits until the app closed, the purpose of my 'server' was to do that
and fire a message back to MEditor should the app signal an error).
The program is just a proof-of-concept test for that, flawed and
unfinished. I just wondered if it worked on XP, as a possible
alternative. BTW, is Display Server written in Eu?
I shall cease and desist if you like

11. Re: Al Getz Display Server
Alright, now it appears to work. The only problem is that your call to
ShellExecute does not put quotes around the name of the Euphoria file to
run.

It's not only a matter of the times I use it, but also a matter of
how I use it.

I believe you, and I didn't say, that your progranm is useless or
something like that.
I wrote "*for me*", that has something to do with my personal needs.
You can believe me, *I* know my needs.

I already wrote some suggestions for improvement, and "Mr Trick" wrote,
that he also would like to see a scrollbar.

I also think it would be quite cool to allow the application to pass a
function which can be called by the display server to obtain the
current values (and format) of selected named variables, and save the
position for use in one session to the next, eg.
integer v1
integer init1 init1=3D0
sequence v2
integer init2 init2=3D0
...
v1=3D??
init1=3D1
...
function ServerCallBack(sequence name)
if equal(name,"v1") then
if not init1 then return {"<no value>","%s"} end if
return {v1,"%d"}
end if
if equal(name,"v2"......
end function
SetServerCallBack(routine_id("ServerCallBack"))
