1. Windows 95/NT Screen Saver in Euphoria
Hi Euphorians!.
Does anybody know where to find information about how to write a
Screen-Saver program in Euphoria?.
Is any special requirement?. I've seen that screen savers under Windows are
conatained in files ".SCR".
Where can I find information of that kind of special programs?.
Any help will be very welcome.
Happy new year to everybody.

A screen-saver..
Bind your program to an .exe
Rename it to a .scr and copy it to your system directory.
It will now show up as a screen saver.
When you choose Configure in the cotrol panel, your program is started with
the '/c' option (as the command line)
When the screensaver needs to be start, it starts up with '/s'

Yes, but.....
Bind it with Bindw only (Can't make a DOS program a screen saver).
How do you make the screen saver properly compliant with mouse and keyboard
movement, hot spots, previews (W95) etc. All non-trivial stuff.
And (the killer as far as I'm concerned. How do you get rid of the console
window. As far as I see in the Alpha release ( page 2 platform.doc) the WIN32
Euphoria programs will ALWAYS have a console window associated with it.
Ralf, did you actually try to make a screen saver. Sure you can run a bound
program from the screen saver config panel. This is NOT a screen saver.
Has anyone actually had any luck. Can anyone post an example if I am wrong.

P.S. Check out Francis Bussiere's EW32 DLL wrappers for Euphoria. This makes
windows programming possible and fun.

Yes, you can.. do you think windows cares that your program is dos or
windows based, it just launches it.
I have never tried this, but it must work..
>How do you make the screen saver properly compliant with mouse and keyboard

I have never tried to make this, but windows delivers no support for
this at all, so you'll have to make a program that will abort () when the
mouse moves, or when a key is hit. In dos this would be fairly easy..

>Euphoria programs will ALWAYS have a console window associated with it.
Yes, but you van give your full-screen screensaver the focus, and then
the console window will be hidden, when your program looses focus, then your
program will simply abort, and the console window will dissapear, I really
don't
think this would be a problem.
BTW You could also bind it with bind (if it's dos based, but the pif of
the file should make sure, that no window-key tricks are allowed
(ctrl+escape, etc.)
If pifs don't work, there are same ASM hackers that will turn it off
(for as long as your program runs)

Yes, many years ago, in visual basic.
It worked the same way, only I'm not 100% sure what command line options
will be set, when the user needs to configure the screensaver..
(BTW It worked this way with win311, but windows is backwards
compatible)
>Has anyone actually had any luck. Can anyone post an example if I am wrong.
Maybe in a day or two, i'll fix something up. This really isn't so hard.
(BTW: The preview will just start up your program, only I do not know how to
do the mini-preview in win95, but because it has to be backwards compatible
I suppose the only requirement for this would be that your program is a
windows(32) program..)
>P.S. Check out Francis Bussiere's EW32 DLL wrappers for Euphoria. This

Yes to all, this is the way windows programming and wrappers should be
done.....
(It's small, clean, safe, and can be updated when the program is already
in wbinded form)

Yes, I think windows DOES care. I have tried this and it does not work.
Try it before posting next.
(Please prove me wrong !)

Sure, from Euphoria windows ? No mouse support routines like Dos.
(Get_mouse is DOS32 only - page 26 Library).

Good point, worth persuing. I'll try something like this. (inelegant though)

What on earth are same ASM Hackers ?

I think you mean, No not in Euphoria ever. Sure VB Screensavers work, as do
C screensavers and many other languages. I would like to see an Euphorian
Screensaver though.

Please do. I think it's harder than you claim.

I've never actually tried to make one either,
but my copy of VB Unleashed outlines it pretty
much as Ralf has said;
-Write a prog with some pretty graphics.
-Add a routine to check the keyboard/mouse and
terminate the prog on any input.
-Rename the .exe to .scr
