Threads in Win XP

Question

Hi i have a program in which i have more than one thread, the problem is, threads are responsible to listen to some socket connections. However at somewhere i need to read data from other thread's sockets, to do this i suspend the thread which is listening that socket and after i read the data, i resume that thread, the problem is the program works fine in Win 98 but does not work in Win xp, probably it is because of i try to suspend the thread but i couldn't find any solution, can anyone help me ?
regards,
Yesildal,

Instead of suspending and resuming , maybe i can
pass a message from clienthandler2 to clienthandler1
but that will mess the things up since i use this
suspending and resuming in so many places... I need
an easier solution...Migrate your use of suspend/resume to use wait/notify instead. Hasn't suspend been deprecated since Java 1.1?! Why are you still using it in a Java 1.4 app?
Basic steps to move from suspend/resume to wait/notify...
* Define or locate a shared object, which will be the lock. If you have a static member in the ClientHandler class, or even the ClientHandler.class will work for this.
* When you call suspend (On the current thread only!), replace this with a synchronized call to waitsynchronized (lock) {
    while (lockInvariantIsTrue) {
        try {
            lock.wait();
        } catch (InterruptedException ie) {
            ie.printStackTrace();
            // break?
} // end synchronized block* When you call resume (For a particular thread), replace this with a synchronized call to notifyAllsynchronized (lock) {
    makeLockInvariantFalse();
    lock.notifyAll();
}To debugging your switchover, there are command-line options to display thread activity with regards to monitors and locks (java -Xrunhprof:monitor=y in Java 1.3.0 Win32)
More information on correct use of wait/notify can be found in various articles in www.javaworld.com and elsewhere. Concurrent Programming in Java (Doug Lea) is apparently an excellent resource (which I haven't found the time to read yet), and Effective Java (Joshua Bloch) also makes some very useful points with regards to multithreaded programming.
Hope this help,
