Then I have function where i call load_image_from_stream: void loading(GtkWidget* widget ,MainWin* mw) { GInputStream* input_stream; input_strea...
I'm re-working a Java executable that may be started multiple times, and I want the process to proceed one at a time. In C# I would do this with a named/system Mutex, but this doesn't seem to be possible in Java. How can I achieve this functionality? ...
I wrote a thread, it is taking too much time to execute and it seems it is not completely done. I want to stop the thread gracefully. Any help ? ...
Hello everyone, I need to connect my android to a bluetooth device. I use the BluetoothChat sample from Google. I had some trouble to do this with a Google Nexus one, because the Nexus was making the connection but disconnects right after. I need to initiate twice time the connection as workaround (see connectionLost()). Now, it works...
Hi, I'm new to threading in C#. Is there anyway of setting a timeout for a thread without blocking the calling thread (in C# 3.5)? If not, is it logical to execute a function using a thread and within that function create a thread and join it to overcome this main thread blocking issue? To illustrate: Instead of: Public void main() { ...
I wonder where is the verge after which a thread pool should be used. How many new threads per second can I create without using a thread pool still avoiding noticeable performance penalty? Are there any observable open-source thread-pool implementations? ...
When you have a COM client that exposes an Interface for an out of proc COM server to access, do you have to register the type library or .idl file with the system for the server to be able to access the interface? I'm not sure if I can generate a proxy/stub DLL from this client process to register with the system. Does it matter in wh...
My software requires to store the directory and registry structure for some particular locations. This usually takes a long time. Let's say I have a method called SaveState() which does that. I want to wrap this into another method, SaveStateWithProgress(), so that when I call it, a modal dialog appears, which shows a simple progress ba...
Guys, I am trying to write to different pieces of a large file using multiple threads, just like a segmented file downloaded would do. My question is, what is the safe way to do this? Do I open the file for writing, create my threads, passing the Stream object to each thread? I don't want an error to occur because multiple threads are ...
I am running a background worker thread that takes a long time to run. The actual function stores the folder structure of a location, but we can take an example of the following pseudo code running in a different thread - private int currentResult=0; private void worker() { for(int n = 0; n<1000; ++n) { int result; ...
Does someone have a simple example of threading in c? I want to build a small console app that will read a txt file file line by line and then use threads to process the entire txt. How should I do this? splitting the txt into X where X=N of threads, is the first thing that comes to my mind, is there a better way? ...
Hi, Is in multithreaded application suitable to have 1 connection per 1 connected client? To me it seems ineffective but if there is not connection pooling, how it could be done when one wants to let each connection communicate with DB? Thanks ...
Is there a possibility to set priority to tasks which are executed by Executors? I've found some statements in JCIP about it's possible but I cannot find any example and I cannot find anything related in docs. From JCIP: An execution policy specifies the "what, where, when, and how" of task execution, including: ... ...
I have a program whose only purpose is to drive a java.awt.Robot in an infinite loop until an exit condition is met. The robot performs a number of actions in quick succession, which require a standard UI delay between them. For this, I use java.awt.Robot.setAutoDelay(int ms), which appears to be designed for precisely this purpose. At...
Hi, I have two threads and one class. Thread1 updates the local object of the class via 3 different methods. The local object (behind the scene) uses some sort of ArrayList to store data. Three methods (mentioned earlier), are doing something with elements of the list... Thread2 queries the local object (content of array list). PROBL...
Hi! I've been trying to figure out how to use System.Threading.Tasks to asynchronously invoke a synchronous WCF method while supporting cancellation, error handling, result-return and multiple continuations. I've come across a number of incomplete demos but they all seem to fall a bit short. As an example I can't use cooperative cancel...
I need all of my threads to check periodically that they should still be running, so that they can self-terminate when the program ends. For all but one of them, this is just a matter of checking a state variable, but the last one is a user-interaction thread, and its loop will wait indefinitely on user input, only checking the state var...
I have a windows forms application (.NET C# 3.5)... that is throwing an error.. but I have 2 scenarios: Client: on the client side.. the error is logged into a log.txt file.. AND an error pop up message appears See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ***** Ex...
Consider the following C++ member function: size_t size() const { boost::lock_guard<boost::mutex> lock(m_mutex); return m_size; } The intent here is not to synchronize access to the private member variable m_size, but just to make sure that the caller receives a valid value for m_size. The goal is to prevent the function f...
