This question already has an answer here: How do I create a C++/CLI Winforms app in VS2012? 1 answer This issue has been around for all Visual Studio versions, but in VS 2015 the "old tricks" don't seem to work anymore. This is what I have tried
I have a std::thread waiting and reading from a socket. And there is a pointer to this thread stored somewhere. But when something bad happens and the thread ends, I want it to call something that results in a function that will join this thread and
I am trying out some simple boost::thread code, as follows: #include <iostream> #include <boost/thread.hpp> void InputLoop() { std::cout << "Loop start" << std::endl; int y = 0; while (1) { std::cout << "y = &q
I have been trying to implement a simple tcp server using boost, that accepts a client connection, and sends some information back to the client by the call of a method exposed by the server. Here is the class I created, based on the Boost tutorials:
I have coded a JPG decoder as such for each dataunit{ decode transform write to rgb buffer } Then I coded it with boost threads as such for each dataunit{ decode } for each dataunit{ transform } for each dataunit{ write to rgb buffer } ...running the
I am looking for a way(preferably with boost threads), to interrupt a thread if it has not joined. I start multiple threads, and would like to end any of them that have not finished by 200 milliseconds. I tried something like this boost::thread_group
I have two threads trying to lock the same boost::mutex. One of those threads is continuously processing some data, and the other is periodically displaying the current state. The processing thread, according to my intention, releases the lock very f
In my program, it start a boost thread and keep the handler as a member of the main thread. When user press the cancel button I need to check the started thread still running and if it is running need tho kill that specific thread. here is the pseudo
I am making a simulator of planets in space, and the issue is, that I cannot simulate more than ~100 planets, because the simulation slows down exponentially. To solve this problem, I thought using threads could solve my problem, since I am probably
I'm in the process of attempting to port some code across from PC to Ubuntu, and am having some issues due to limited experience developing under linux. We use CMake to generate all our build stuff. Under windows I'm making VS2010 projects, and under
What I would like to know about the code below, is: Are the use of try catch blocks around method calls good practice. What are the follies in the code below? #ifndef TIMER_H #define TIMER_H #include <boost/bind/bind.hpp> #include <boost/date_tim
I'm using a third party library which has a blocking function, that is, it won't return until it's done; I can set a timeout for that call. Problem is, that function puts the library in a certain state. As soon as it enters that state, I need to do s
What happens when a thread is put to sleep by other thread, possible by main thread, in the middle of its execution? assuming I've a function Producer. What if Consumer sleep()s the Producer in the middle of production of one unit ? Suppose the unit
I am new to Boost threading and I am stuck with how output is performed from multiple threads. I have a simple boost::thread counting down from 9 to 1; the main thread waits and then prints "LiftOff..!!" #include <iostream> #include <bo
For the sake of learning combinatorics of boost::thread I'm implementing a simple barrier (BR) for threads which lock a common mutex (M). However, as far as I get it when going to BR.wait() the locks on the mutex are not released, so in order for all
I'm writing a multi-threaded server using boost::asio (for sockets), boost::thread (for threading), libconfig++ (for configuration files reading) and protocol buffers (for the protocol implementation). The server follows more or less this route: main
MinGw 4.7.0 Boost 1.47 code: #include <iostream> #include <boost/thread.hpp> int main(int argc, char *argv[]) { std::cout<<"In main"<<std::endl; } Compiler string: g++.exe -Wall -fexceptions -g -IC:\soft\ides_comp\mingw\i
Consider, say, a collection of account balances. And then you have a complex function that needs to check the balances of a few different accounts and then adjust the balances of a few different accounts. The operations need to be atomic with respect
Normally I can google my way around and find solutions, but not this time. I'm using 64 bit Linux Ubuntu 11.04 to compile a 32 bit windows application. I'm using i586-mingw32msvc-gcc to compile my C++ files. test.cpp: #include <boost/asio.hpp> makef
I have a program where I use boost::threads for multi threading. Unfortunately drd (valgrind --tool=drd ./my_program) reports lot of problems about 10000. I am not sure if I misunderstood something of boost thread. I try to find out my error for hour
I my new application I have flexibility to decide the use of library for multi-threading. So far I was using pthread. Now want to explore cross platform library. I zero in on TBB and Boost. I didn't understand what is the benefit of TBB over Boost. I
First off, I hope my question makes sense and is even possible! From what I've read about TCP sockets and Boost::ASIO, I think it should be. What I'm trying to do is to set up two machines and have a working bi-directional read/write link over TCP be
Is it thread safe to post new handlers from within a handler? I.e. Can threads that called the io_service::run() post new Handlers to the same io_service? ThanksIt is safe to post handlers from within a handler for a single instance of an io_service
How do I handle the control-C event or stop my boost::asio server. I have a tcp & udp combined server and would like to be able to exit cleanly when I press ctrl-c. I get a first chance exception for unhandled control-C. Here is my code void startTCP
My idea was to create X threads, run it using KeepRunning method which has endless loop calling _io_service.run() and send tasks to _io_service when received a new connection using _io_service.poll() in async_accept handler. I run the server with a c
http://www.boost.org/doc/libs/1_46_0/doc/html/boost_asio/example/chat/chat_client.cpp I am working on client application based on he example above. I wanted to do the client connection in separte thread so that UI doesnot get stuck.Here UI is getiing
For Windows 7 and/or Windows Server 2008, is there any specific difference in thread priority level or class between hidden windows and visible windows? In other words does the OS deprioritize the application?I don't think there is a difference betwe
I'm using libcurl in C++, and I'm calling curl_easy_perform in a separate thread from my UI using Boost.Thread. The main UI has a cancel button that I'd like to be perfectly responsive (i.e., when a user clicks on it, it should immediately react). I
Could you tell mw what is the problem with the below boost::thread program #include<iostream> #include<boost/thread/thread.hpp> boost::mutex mutex; class A { public: A() : a(0) {} void operator()() { boost::mutex::scoped_lock lock(mutex); } pr
I have a worker class like the one below: class Worker{ public: int Do(){ int ret = 100; // do stuff return ret; } } It's intended to be executed with boost::thread and boost::bind, like: Worker worker; boost::function<int()> th_func = boost::bind(&
