It normally works like this:

  - You write a dedicated class, let's call it MyTask, to perform your task.
This class must inherit the Task class.
  - The constructor of MyTask can receive some arguments for the task, like
an array of recipient addresses and bodies for your batch email.
  - After the MyTask object is created, the process fork is postponed to the
next invocation of the event loop. You may want to keep this in mind if
you sometimes start a whole bunch of tasks at once or if you want to
wait for the results of your task in the current procedure. To have the
tasks started, you either have to enter the event loop, either by
rolling up the current code path or by calling Wait.
  - The interpreter will then fork and jump into the Main() method of the
MyTask object. The standard output of the new process running the Task
is redirected into the main program and raises Read events of the Task
object. You can also return serialisable data from the Main() method
which is transferred into the main process and which you can fetch these
using MyTask.Value.
  - Because returning a single value at the end of the task may not be
sufficient, you normally end up using the standard output to communicate
more regularly with the main process. I could imagine that you want to
send messages of the form:

"sent\tx\tn"

to your main process, indicating that you just sent the x-th email of
n emails total. The main process intercepts this string, has to parse it
and can then update a ProcessBar or something. This is the way I use
Tasks in my projects, anyway.

An example can also be found in the gb.form component. The FileView class
uses a background task named CTaskPreview to make preview of images in the
background and send them to the main process once they're ready.

Tobi

for my feel, i prefers using multiple process objects or if i use
httpClient multiple client.

There is an exemple of use in the gb.map source (tilemap) of multiple
http server client
