1. Virtual Thread Manager 02 now available
Hello again,
The new Win thread manager (02) is now called "Virtual Thread Manager".
It doesnt use OS threads but makes the app seem like it does.
It's got a true scheduler and you can set priority by using a greater
or lesser amount for the time slice for each thread. Useage is fairly
straightforward but see the docs and the demos for required function
calls and basic code structure.
There are two 'sub versions' of 02, one for WinClass and the other for
WinLib, along with one demo for each. Make sure to run the correct demo
for the Win library you intend to use. Useage is the same for either.
Any ideas/suggestions welcome.
BTW, i see what Matt was talking about now when he said "Langwar".
I took a look at that, but it looks a lot more complex and harder
to use or did i miss something?
Take care,
Al
And, good luck with your Euphoria programming!

The LangWar Task Scheduler is a nice little library when stripped of
its LangWar-specifc data. IMHO, Rob should move the library to the
INCLUDE folder instead of the LangWar folder, and make it a general
use library with better documentation.
I was working on adapting the LangWar Task Scheduler to Windows in
general (regardless of library) using Multimedia Timers to trigger the
various next_task() calls and what not. I'm at work right now, so I
don't have the code in front of me. I think I ran into issues with the
Multimedia Timers crashing because they actually use a thread to keep
proper time, and as we all know, threads crash Euphoria. I had it
working with setTimer() in Win32Lib, but like I said, I wanted it to
be library-independant. I supposed I could pick up on it again....

Hi Greg,
You wont have to now :)
There are two libs one for WinClass and one for WinLib, and im
soon going to have one for Arwen and a general purpose lib for
any Windows lib.
I still prefer my older version 01, at least when it can be used,
because there's less housekeeping to do with that one.
I took a quick look at Langwar and it's cute, but i dont understand
it fully yet. I guess Rob sets up his own timer or something? Not
sure if that would work very well under Windows unless you dont have
to process messages as well as the 'threads' ? Cant have anything
hogging the whole (single) thread or messages dont get dispatched.
Havent looked at this that in depth yet however, and i'll probably
end up moving on to something more pressing for my personal needs
anyway...i still havent completed my Appointment Calendar the
way i want it to be.
Take care,
Al

Hey, Don, you're welcome. I hope it helps with your app the
way (the first version) helped with some of my apps.
If you have any ideas let me know too...
I'd be happy to try your 'dates' program when it's available.
Perhaps sometime later today?
Take care,
Al

Hi Al,
It is one of the good names for these threads, I think.
Say, it seems to be, FreeBasic and Ruby (multiplatform langs
like Euphoria) have the non-OS threads, FreeBasic even for
DOS, but their 'quasi-threads' named as just 'threads' and
it is a source of confusions (correct me please, if I'm wrong).
But Euphoria has some form of this multitasking feature just
from v1.0, and under pure DOS, and without any noise. 
And non-OS threads seem to be a very simple and robust
solution of multitasking for the multiplatform languages at all.
Good Luck!

Hi Igor!
Thanks, and i hope you find it useful too. It seems pretty easy to
use but if you find any difficulties i'd like to hear about them.
Threads always make the code a little harder write and understand,
but for some things they are really needed. Before i found some
means to achieve thread like operation i couldnt call more than
one function at a time...and if it took 20 seconds to complete
i'd have to sit there and wait it out and put up with the app paint
messages getting clogged up and not reaching the WinProc so the app
appeared to freeze even though it was running normally...and if you
clicked on another window that overlapped your app window it would
mess up the normal windows painting, which of course wouldnt correct
itself until after the long operation was done...how nice to see only
half a window there!
Now that nastyness is all gone :)
Take care,
Al
