I've been trying to create an instance I can pass a variable through different threads. This variable (can be an object) is singleton, that means if a thread changes its value then it must be the same for all threads.

I would like the form that's executing the thread be able to get the variable as well.

Design:

UI -> Service
Service acknowledges the UI params then
Service sends response messages to the UI.

Just wondering is there a way to achieve it, or anyone here has any experience with it plesase share? Thanks!

Quite difficult what your intenstions are.

If acknowledging the parameters and sending a reply can be made with forum callbacks than just pass the forum and call it's callbacks.
I think autopilot once made a tutorial about calling a form from another thread.

yeah ... it is ... I got myself confused through these threads. It's hard to pass reference through memory.

I just solved my own question ... YAHOOO !!!! finally !!
