Given that we rely on the JVM thread scheduling algorithm I'm reasonably sure this isn't possible, but I was wondering if there's any techniques you can ...

Because OnStart() requires that it completes and returns to the OS, I have a main method that fires on another thread in a threadpool. My Onstart() mainly looks like this protected override void OnStart(string...
Hello everybody, my application works as a middle ware, receiving requests from clients, then transforming it in certain logic and sending the transformed requests to another service provider as normal HTTP requests or Webservice soap requests. The application was deployed on two jboss servers (in cluster) behind a load balancer. let's...

I have this "interesting" problem. I have this legacy code that looks like int main() { while(true) { doSomething(); } } I would like to duplicate that doSomething() in many threads, so that now main() would look like int main() { runManyThreads(threadEntry) } void threadEntry() { while(true) { doSomething(); } } ...
I have read that we can not access anything in the main UI thread in Silverlight application from other worker threads. So why it is possible to access an object of class System.Windows.Threading.Dispatcher which is associated with the main UI thread from other worker threads when we want to delegate some work to be done on the User Int...
I have two questions is one here. On Windows, I am familiar with pipes and how they work. However, I am curious as to what mechanism the OS uses to notify the recipient thread of a message arrival. Does the thread "poll & sleep" continuously for data? Does the OS check to see if the thread is sleeping and wake it up? Or is there some o...
I want to run several threads inside a process. I'm looking for the most efficient way of being able to pass messages between the threads. Each thread would have a shared memory input message buffer. Other threads would write the appropriate buffer. Messages would have priority. I want to manage this process myself. Without getting in...

Since a socket is full duplexed, meaning you can send and recieve simultaneously. So, is the .NET Socket Send()/Receive() thread-safe? I need to Send() and Receive() in 2 threads. ...
Hi, recently i've got a dispute about using static methods in a class that is used by hundreds threads. In my opinion the "first" solution has no special benefits except it is easier to use for the client of class but i have been told that it is extremely bad idea and I have to use the "second" solution. Can anyone give me clear explan...
