Hello Roger, I appreciate your help and others as well. I understand your points and they are helpful. But what I want to do it to port some Windows Mobile applications, which use true multi-task (multi-thread more accurately).
The differences of multi-task senses between my application and the solution you mentioned are, 1. Not a hacking way by using un-documented features; 2. Callback function is not working in all cases of a true multi-threaded (for example, an elegant producer -- consumer case, backtest sample in financial stock exchange simulation -- one thread to simulate one user to make stock deal, other types of games ...). Because callback function works on per notification basis, but multi-task application concept is beyond that. What I concern is the *true* multi-task environment, which supports generally all kinds of multi-threaded application (for example, the two samples I listed above). Could Palm OS 5.2 be capable of doing it? regards, George ----- Original Message ---- From: Roger Stringer <[EMAIL PROTECTED]> To: Palm Developer Forum <[email protected]> Sent: Wednesday, December 13, 2006 12:05:08 AM Subject: Re: multi-threaded application in Palm OS 5.2 You are trying to over-think the situation and you've received good information in response to your prior e-mails. Palm OS has one foreground user task. But other programs can and do get called in the background in response to Launch codes and Notifications. So you need read the documentation on those two, and understand them. Roger Stringer ____________________________________________________________________________________ Do you Yahoo!?
