• How can i Import a Managed C# dll into a Win32 C++ project ?

  - by Agito

  I am working on a solution, most of its core engine is developed as Win32 C++ (and is Platform independent and is also used on OS X), some time ago we needed to call C++ dll's of core engine from C# and I was able to Load main solution's DLL in C# (by the help of some threads here on SO). but now we have certain things implemented in Managed C# dll and need to use it in Win32 C++ project? (and just function definitions and dll are provided)

• performSelectorOnMainThread equivalent in Java for Android

  - by Daniel A. White

  I have an iPhone application and I am porting it over to Android. I have a service/controller that spawns new threads to perform some network tasks. I use performSelectorOnMainThread in my iPhone app. How can I have my Java app do the same or similar thing?

• Does OpenCL allow concurrent writes to same memory address?

  - by Wonko

  Is two (or more) different threads allowed to write to the same memory location in global space in OpenCL? The write is always changing a uchar from 0 to 1 so the outcome should be predictable, but I'm getting erratic results in my program, so I'm wondering if the reason can be that some of the writes fail. Could it help to declare the buffer write-only and copy it to a read-only buffer afterwards?

• What does composability mean in context of functional programming?

  - by Surya

  What do functional programmers mean when they say a certain thing is composable or not composable? Some of the statements of this sort that I've read are: Control structures are not composable. Threads do not compose. Monadic operations are composable.

• What the best multi-thread application debugger for C++ apps.

  - by Coredumped

  I'm looking for a good multi-thread-aware debugger, capable of showing performance charts of application threads on Linux, don't know if such a thing exists, perhaps as a Eclipse plugin. The idea would be to track per thread memory allocation a CPU usage as well as being able to interrupt a thread and examine its stack trace, local vars, etc. It does not have to be an eclipse plugin or a free tool, do any of you have heard of something similar?

• What is better and why to use List as thread safe: BlockingCollection or ReaderWriterLockSlim or lock?

  - by theateist

  I have System.Collections.Generic.List _myList and many threads can read from it or add items to it simultaneously. From what I've read I should using 'BlockingCollection' so this will work. I also read about ReaderWriterLockSlim' and 'lock', but I don't figure out how to use them instead ofBlockingCollection`, so my question is can I do the same with: ReaderWriterLockSlim lock instead of using 'BlockingCollection'. If YES, can you please provide simple example and what pros and cons of using BlockingCollection, ReaderWriterLockSlim, lock?

• JVM with no garbage collection

  - by HH

  I've read in many threads that it is impossible to turn off garbage collection on Sun's JVM. However, for the purpose of our research project we need this feature. Can anybody recommend a JVM implementation which does not have garbage collection or which allows turning it off? Thank you.

• stm monad problem

  - by Alex

  This is just a hypothetical scenario to illustrate my question. Suppose that there are two threads and one TVar shared between them. In one thread there is an atomically block that reads the TVar and takes 10s to complete. In another thread is an atomically block that modifies the TVar every second. Will the first atomically block ever complete? Surely it will just keep going back to the beginning, because the log is in an inconsistent state?

  - by smwikipedia

  Hi guys! I am developing a multi-thread application and one of my threads is somehow blocked by something and thus it will occupy some resource such as a file forever.

• Is there a way to reliably detect the total number of CPU cores?

  - by John Sheares

  I need a reliable way to detect how many CPU cores are on a computer. I am creating a numerically intense simulation C# application and want to create the maximum number of running threads as cores. I have tried many of the methods suggested around the internet like Environment.ProcessorCount, using WMI, this code: http://blogs.adamsoftware.net/Engine/DeterminingthenumberofphysicalCPUsonWindows.aspx. None of them seem to think a AMD X2 has two cores. Any ideas?

• Why do I have to pay for something that I'm not using?

  - by Knowing me knowing you

  Guys just finished reading one of my college books about threads in Java and I was informed that lock - what ever it is, is in Object class. So it looks like even though I'm not using threaded classes my objects will be heavier because of that? Don't you think that it's a bit annoying and unfair to expect from anyone to pay for something s/he have not intention of using? Thanks

• Is it expensive to hold on to PreparedStatements? (Java & JDBC)

  - by sbook

  I'm trying to figure out if it's efficient for me to cache all of my statements when I create my database connection or if I should only create those that are most used and create the others if/when they're needed.. It seems foolish to create all of the statements in all of the client threads. Any feedback would be greatly appreciated.

• Maintaining many socket connections with a single thread

  - by John

  Many tutorials on socket communication I see seem to use 1 thread per socket. But on a server used for online gaming, you might have 10k concurrent users - 10k threads isn't probably a wonderful idea. I came across a tool (SmartFox) which claims to use a single thread for monitoring all socket connections, potentially thousands of them. This app happens to be in Java, but I figure C++ or C# could do the same... how would you achieve this?

• Ruby Win32Api get single character non-blocking

  - by Markus Orreilly

  I'm trying to write a simple game working with two threads, one thread to get input from the user, and another thread to animate some scenes. I'm able to get characters without pressing ENTER just fine, but it blocks in the animating thread until the user presses a key. Does anyone know of a way to get a character from the keyboard non-blocking?

• ID generator with local static variable - thread-safe?

  - by Poseidon

  Will the following piece of code work as expected in a multi-threaded scenario? int getUniqueID() { static int ID=0; return ++ID; } It's not necessary that the IDs to be contiguous - even if it skips a value, it's fine. Can it be said that when this function returns, the value returned will be unique across all threads?

• UIView animation cancels previous animation?

  - by user281300

  Hi I have an NSTIMER that counts the time, and on t = 10, it fires an animation but during that time it might happen that another animation is running. This causes the previously running animation to cut off. Any idea? i thought UIVIEW animations were ran in diff threads. I cannot use a willstop selector here since t = 10 might happen while another animation is running and might not have ended yet.
