1. Multitasking/Eu/WinLib
Is there a way to make a true task manager in Eu? Is there a way to access
the windows taskman and give it different sections of code to run?
If so can it be a eu function or procedure or would i have to use a dll?
PS I am using WinLib, that doesn't help does it

Euphoria doesn't support multitasking, so while it is possible to make the
right system calls (I've tried on Linux), the program gets really messed up.
I wrote a cooperative multitasking type library (ESE or an Event System for
Euphoria) which does events as well as simple multitasking, but
id doesn't use real threads and you have to program each section between task
switches. It works fairly well for simple things, though. For example,
you can use it in a game to play sounds on the PC speaker "at the same time"
as you are accepting key events etc. My game programming library uses this
extensively.

This is a big question and something that I would like to see added somehow.
I have a problem with load times and morfit with huge worlds, and disable
their load screen and their progress bars. Unfortunately, without threads,
the window stops responding until the task has finished - and it can take
some time on slow machines as Im playing with 14,000 polygons.
Can any of our windows experts think about a way to address threads and
win32? With threads I could check the progress of the task and of course
refresh the main window so it doesnt stop responding.

I got around the problem by creating separate running exw
sessions, and having them communicate via winsocks. I don't have a
taskmanager, but you could write one for this in Eu. You can use
"run" to run them, and a quit command sent via socks to kill them. I
presume you can use this method to run partA of Program in linux
on one box, and partB of program in windoze on another computer
via ethernet. the threads run this way must be totally separate, as
they are running from separate exw.exe directories. If you want
them to share info, you must send and recieve that info. If you do
this on the same computer, you could be able to grab slices of
memory, like a virtual screen buffer, and have each partX of
program control each section. No section need be fixed, but how to
get permissions from the OS to grab each slice, i don't know.

It would help to write the socks code, but i know little of winlib
otherwise.
