    - by Tim
    My OS is Windows 7. I try to download Adobe® Acrobat 9 Pro for English and Windows (326.6MB) by its Akamai Download Manager and then click on "Install Now".

I click yes, but then: Launching File Failed: se_err_accessdenied Anyone has some idea why and how to fix it? Thanks and regards!

  • When and why will an OS initialise memory to 0xCD, 0xDD, etc. on malloc/free/new/delete?

    - by LeopardSkinPillBoxHat
    I know that the OS will sometimes initialise memory with certain patterns such as 0xCD and 0xDD. What I want to know is when and why this happens. When Is this specific to the compiler used? Do malloc/new and free/delete work in the same way with regard to this? Is it platform specific? Will it occur on other operating systems, such as Linux or VxWorks? Why My understanding is this only occurs in Win32 debug configuration, and it is used to detect memory overruns and to help the compiler catch exceptions. Can you give any practical examples as to how this initialisation is useful? I remember reading something (maybe in Code Complete 2) that it is good to initialise memory to a known pattern when allocating it, and certain patterns will trigger interrupts in Win32 which will result in exceptions showing in the debugger. How portable is this?

  • IIS 7 Web service access

    - by Aharon Manne
    I am trying to debug a simple web service. I have IIS 7 installed on my development machine (Windows 7), and have installed the web service. I can access it from my development machine, but not from any other machine in the local network.I opened the firewall to HTTP access, and I can access the default website from other machines, so it is not the firewall.What security settings should I look at to try to allow devices on the LAN to access the web service?

  • what happens to running/blocked runnables when executorservice is shutdown()

    - by prmatta
    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 running or blocked? Does the ExecutorService wait for those threads to complete before it terminates? The reason I ask this is because a long time ago when I used to dabble in Java, they deprecated Thread.stop(), and I remember the right way of stopping a thread was to use sempahores and extend Thread when necessary: public void run () { while (!this.exit) { try { block(); //do something } catch (InterruptedException ie) { } } } public void stop () { this.exit = true; if (this.thread != null) { this.thread.interrupt(); this.thread = null; } } How does ExecutorService handle running threads?

  • How do you google bad reviews? [closed]

    - by zlog
    The first thing I like to do before I make technology choices or gadget purchases is find bad reviews of the things. That way, taking into consideration of the potential biases of the reviewer, I can evaluate the product/service for the worse it can be. How do people google (or search in general) for bad reviews? I usually just try googling "bad review [product/service]" or "[product/service] sucks", but I'm sure there are better ways.

  • How can I ensure that a Java object (containing cryptographic material) is zeroized?

    - by Jeremy Powell
    My concern is that cryptographic keys and secrets that are managed by the garbage collector may be copied and moved around in memory without zeroization. As a possible solution, is it enough to: public class Key { private char[] key; // ... protected void finalize() throws Throwable { try { for(int k = 0; k < key.length; k++) { key[k] = '\0'; } } catch (Exception e) { //... } finally { super.finalize(); } } // ... }

  • How to Stop Current Playing Song When using one thread with JLayer?

    - by mcnemesis
    I recently used a solution to the one-thread-at-a-time problem whe using Jlayer to play mp3 songs in Java. But this solution by Kaleb Brasee didn't hint at how you could stop the player, i.e how could one then call player.close()? Kaleb's code was: Executor executor = Executors.newSingleThreadExecutor(); executor.execute(new Runnable() { public void run() { /* do something */ } }); and this is the code I put in run() if(player != null) player.close(); try{ player = new Player(new FileInputStream(musicD.getPath())); player.play(); }catch(Exception e){} The problem is that much as this solves the problem of keeping the gui active while the music plays (in only one other thread -- what i'd wanted), I can't start playing another song :-( What could I do?

  • Jquery background overlay/alert without .onclick event - php responder?

    - by Philip
    Hi guys, I have no experience with jquery or javascript for that matter. I am trying to implement this technique to respond to users for errors or messages in general. lights-out-dimmingcovering-background-content-with-jquery This method uses the onclick event and that's not what im after, I have tried to replace .onclick with .load but that doesn't seem to work. I'm after a quick fix as I really don't have the time to learn jquery or its event handlers. The goal is to catch any errors or message's and once these are called the alert box is called without any further actions such as .onclick. How my code would look: {PHP} $forms = new forms(); if(count($forms->showErrors) > 0 // or == true) { foreach($forms->showErrors as $error) { print('<p class="alert">'.htmlspecialchars($error, ENT_QUOTES).'</p>'); } }

  • Silverlight file upload - file is in use by another process (Excel, Word)

    - by walkor
    Hi, all. I have a problem with uploading of the file in Silverlight application. Here is a code sample. In case when this file is opened in other application (excel or word for example) it fails to open it, otherwise it's working fine. I'm using OpenFileDialog to choose the file and pass it to this function. private byte[] GetFileContent(FileInfo file) { var result = new byte[] {}; try { using (var fs = file.OpenRead()) { result = new byte[file.Length]; fs.Read(result, 0, (int)file.Length); } } catch (Exception e) { // File is in use } return result; } Is there any way i can access this file or should i just notify the user that the file is locked?

  • How to implement cancellable worker thread

    - by Arnold Zokas
    Hi, I'm trying to implement a cancellable worker thread using the new threading constructs in System.Threading.Tasks namespace. So far I have have come up with this implementation: public sealed class Scheduler { private CancellationTokenSource _cancellationTokenSource; public System.Threading.Tasks.Task Worker { get; private set; } public void Start() { _cancellationTokenSource = new CancellationTokenSource(); Worker = System.Threading.Tasks.Task.Factory.StartNew( () => RunTasks(_cancellationTokenSource.Token), _cancellationTokenSource.Token ); } private static void RunTasks(CancellationToken cancellationToken) { while (!cancellationToken.IsCancellationRequested) { Thread.Sleep(1000); // simulate work } } public void Stop() { try { _cancellationTokenSource.Cancel(); Worker.Wait(_cancellationTokenSource.Token); } catch (OperationCanceledException) { // OperationCanceledException is expected when a Task is cancelled. } } } When Stop() returns I expect Worker.Status to be TaskStatus.Canceled. My unit tests have shown that under certain conditions Worker.Status remains set to TaskStatus.Running. Is this a correct way to implement a cancellable worker thread?

  • How should I delete a child object from within a parent's slot? Possibly boost::asio specific.

    - by kaliatech
    I have written a network server class that maintains a std::set of network clients. The network clients emit a signal to the network server on disconnect (via boost::bind). When a network client disconnects, the client instance needs to be removed from the Set and eventually deleted. I would think this is a common pattern, but I am having problems that might, or might not, be specific to ASIO. I've tried to trim down to just the relevant code: /** NetworkServer.hpp **/ class NetworkServices : private boost::noncopyable { public: NetworkServices(void); ~NetworkServices(void); private: void run(); void onNetworkClientEvent(NetworkClientEvent&); private: std::set<boost::shared_ptr<const NetworkClient>> clients; }; /** NetworkClient.cpp **/ void NetworkServices::run() { running = true; boost::asio::io_service::work work(io_service); //keeps service running even if no operations // This creates just one thread for the boost::asio async network services boost::thread iot(boost::bind(&NetworkServices::run_io_service, this)); while (running) { boost::system::error_code err; try { tcp::socket* socket = new tcp::socket(io_service); acceptor->accept(*socket, err); if (!err) { NetworkClient* networkClient = new NetworkClient(io_service, boost::shared_ptr<tcp::socket>(socket)); networkClient->networkClientEventSignal.connect(boost::bind(&NetworkServices::onNetworkClientEvent, this, _1)); clients.insert(boost::shared_ptr<NetworkClient>(networkClient)); networkClient->init(); //kicks off 1st asynch_read call } } // etc... } } void NetworkServices::onNetworkClientEvent(NetworkClientEvent& evt) { switch(evt.getType()) { case NetworkClientEvent::CLIENT_ERROR : { boost::shared_ptr<const NetworkClient> clientPtr = evt.getClient().getSharedPtr(); // ------ THIS IS THE MAGIC LINE ----- // If I keep this, the io_service hangs. If I comment it out, // everything works fine (but I never delete the disconnected NetworkClient). // If actually deleted the client here I might expect problems because it is the caller // of this method via boost::signal and bind. However, The clientPtr is a shared ptr, and a // reference is being kept in the client itself while signaling, so // I would the object is not going to be deleted from the heap here. That seems to be the case. // Never-the-less, this line makes all the difference, most likely because it controls whether or not the NetworkClient ever gets deleted. clients.erase(clientPtr); //I should probably put this socket clean-up in NetworkClient destructor. Regardless by doing this, // I would expect the ASIO socket stuff to be adequately cleaned-up after this. tcp::socket& socket = clientPtr->getSocket(); try { socket.shutdown(boost::asio::socket_base::shutdown_both); socket.close(); } catch(...) { CommServerContext::error("Error while shutting down and closing socket."); } break; } default : { break; } } } /** NetworkClient.hpp **/ class NetworkClient : public boost::enable_shared_from_this<NetworkClient>, Client { NetworkClient(boost::asio::io_service& io_service, boost::shared_ptr<tcp::socket> socket); virtual ~NetworkClient(void); inline boost::shared_ptr<const NetworkClient> getSharedPtr() const { return shared_from_this(); }; boost::signal <void (NetworkClientEvent&)> networkClientEventSignal; void onAsyncReadHeader(const boost::system::error_code& error, size_t bytes_transferred); }; /** NetworkClient.cpp - onAsyncReadHeader method called from io_service.run() thread as result of an async_read operation. Error condition usually result of an unexpected client disconnect.**/ void NetworkClient::onAsyncReadHeader( const boost::system::error_code& error, size_t bytes_transferred) { if (error) { //Make sure this instance doesn't get deleted from parent/slot deferencing //Alternatively, somehow schedule for future delete? boost::shared_ptr<const NetworkClient> clientPtr = getSharedPtr(); //Signal to service that this client is disconnecting NetworkClientEvent evt(*this, NetworkClientEvent::CLIENT_ERROR); networkClientEventSignal(evt); networkClientEventSignal.disconnect_all_slots(); return; } I believe it's not safe to delete the client from within the slot handler because the function return would be ... undefined? (Interestingly, it doesn't seem to blow up on me though.) So I've used boost:shared_ptr along with shared_from_this to make sure the client doesn't get deleted until all slots have been signaled. It doesn't seem to really matter though. I believe this question is not specific to ASIO, but the problem manifests in a peculiar way when using ASIO. I have one thread executing io_service.run(). All ASIO read/write operations are performed asynchronously. Everything works fine with multiple clients connecting/disconnecting UNLESS I delete my client object from the Set per the code above. If I delete my client object, the io_service seemingly deadlocks internally and no further asynchronous operations are performed unless I start another thread. I have try/catches around the io_service.run() call and have not been able to detect any errors. Questions: Are there best practices for deleting child objects, that are also signal emitters, from within parent slots? Any ideas as to why the io_service is hanging when I delete my network client object?

  • Troubles with DateTime and PHP 5.2

    - by Nate Wagar
    I'm attempting to use the PHP DateTime class on a server with PHP 5.2.6, with a test server running PHP 5.3. Here is the code: <?php try { $dt = new DateTime('2009-10-08'); $dt->setDate(2009,10,8); print_r($dt); }catch (Exception $e) { echo $e->getMessage(); } On the test server, things work flawlessly, this is what prints: DateTime Object ( [date] => 2009-10-08 00:00:00 [timezone_type] => 3 [timezone] => America/New_York ) On the server I need to use it on, however, this is what prints: DateTime Object ( ) Removing the setDate makes no difference whatsoever. Any ideas why this might be happening? Thanks!

  • SQL Server Query Editors - any that warn of number of rows to be changed?

    - by ciaranarcher
    We're using SQL Server 2000 Query Analyser, and one issue we have is that very occasionally, when a user is updating our live database, they insert the incorrect/no(!) where clause. I know, not good, but it happens. Are there any editors that will warn of the number of rows that might be changed (if that is even possible) or even a way to configure an editor, if it is connected to a certain database, to prompt for confirmation before the query is run? We have a way to recover our data in the cases where we run an incorrect query, but it takes time, and I'm just seeing if there are any ways to catch the error, or at least give the user a second chance. Thanks in advance.
