I have a project where I send a couple of emails via a seperet thread, to speed up the process for the end-user. It works successfully, but i was just wondering whether there were any potfalls that i might not have considered? My greatest fear is that the user clicks a button, it says that the message has been sent (as it will have been ...
I'm getting a weird threading issue inside a SharePoint workflow that I'd like to learn more about. I'm trying to send an email using SPUtility.SendEmail asynchronously by firing up a new thread to do it. This successfully works at the end of a workflow for a summary email. I tried doing the same to replace a task notification email but ...

I'm working with many threads in a system where I know beforehand the total size of all files. When an observer is notified of a change by the subject it implicitly knows a file segment has been downloaded. I'll change this in the future as it's not explicit. The problem I'm having is that my percentage indicator doesn't get updated i...
Here is a simple thread pattern that I use when writing a class that needs just one thread, and needs to a specific task. The usual requirements for such a class are that it should be startable, stopable and restartable. Does anyone see any issues with this pattern that I use? public class MyThread implements Runnable { private boo...

In Java, to create and show a new JFrame, I simply do this: public static void main(String[] args) { new MyCustomFrameClass().setVisible(true); } However, I have seen many people doing it like this: public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { ne...
When I run Thread.abort_on_exception = true threads = [] threads << Thread.new do loop { sleep 1 } end threads << Thread.new do loop { sleep 1; raise } end threads.each { |t| t.join } as a straight-up ruby script, the script exits as you'd expect with abort_on_exception set to true. But when I try to run this same code as a ra...
Im working on a reporting system, a series of DocumentPage are to be created through a DocumentPaginator. These documents include a number of WPF components that are to be instantiated so the paginator includes the correct things when later sent to the XpsDocumentWriter (which in turn is sent to the actual printer). My problem now is th...
I have a program with 4 threads. Within each thread, I do a luaL_newstate(); Each thread only has access to it's own lua instance. Is there anything I need to worry about? [I.e. is there some hidden state that all lua instances share behind my back?] Thanks! ...
My task was to deal with problem of 5 eating thinkers. Each of them can eat only 10 times. Solution should base on Semaphore. I almost solved the task and output was correct when I simply used println for showing state of each thinker. But there is additional point to store those states in some sort of collection. And somehow I can't mak...

The queries to this external database are sometimes taking a while to run. This lag is experienced through the browser. Possible Solution I want to use threading to eliminate the simu...
I posted a question about a thread pattern today, and almost everyone suggested that I look into the ExecutorService. While I was looking into the ExecutorService, I think I am missing something. What happens if the service has a running or blocked threads, and someone calls ExecutorService.shutdown(). What happens to threads that are r...
I have two UI threads. I want to make sure the first one is finishing running, and then run the other one. How could I do that? Thanks a lot!

I want to set a time limit on a PowerShell (v2) script so it forcibly exits after that time limit has expired. I see in PHP they have commands like set_time_limit and max_execution_time where you can limit how long the script and even a function can execute for. With my script, a do/while loop that is looking at the time isn't appropri...

I was thinking, is it possible to have a lockless queue when more then one thread is reading or writing?

Can/does anyone want to prove it? ...
