  • Android lifecycle of thread-based game

    - by ehehhh
    I ran into a bit of trouble while trying to get my game to work correctly after being put to the background by the user or a phone call for example. My app has a SurfaceView class called GameView, which has the onDraw() method to do all the necessary drawing for my game and two threads - one for calling the onDraw() and one for doing the necessary calculations for the game's logic. I succesfully implemented onPause() and onResume(). (I paused both threads when back button was pressed and resumed them after user cancelled in the AlertDialog.) Now I would like to have the game paused the same way when onStop() gets called. I put both threads on pause and saved my characters location in the savedInstanceState, but when I start my app again, no method gets called (I checked with Logcat). I believe onRestart() should be called first, then onStart() and then onResume(), but none of that happens. What am I doing wrong? (Didn't include any code, because it seems to be a problem of me not understanding the lifecycle, not a problem in code. If it seems necessary, I'll post the parts you request.)

  • Smart Background Thread Task in Ruby on Rails?

    - by elado
    I need to perform a task every 5 seconds, but only when users are using the application. As for now, I use cron that works every minute and activates a task that repeats itself every 5 seconds with sleeps between, for a minute. However, it works also when the application isn't being used. Is there a gem that will do this kind of thing?

  • How to tell the parent that the thread is done in C++ using pthreads ?

    - by milleroff
    Hi. I have a TCP Server application that serves each client in a new thread using POSIX Threads and C++. The server calls "listen" on its socket and when a client connects, it makes a new object of class Client. The new object runs in its own thread and processes the client's requests. When a client disconnects, i want some way to tell my main() thread that this thread is done, and main() can delete this object and log something like "Client disconnected". My question is, how do i tell to the main thread, that a thread is done ?

  • Handle BACK key event in child view

    - by Mick Byrne
    In my app, users can tap on image thumbnails to see a full size version. When the thumbnail is tapped a bunch of new views are created in code (i.e. no XML), appended at the end of the view hierarchy and some scaling and rotating transitions happen, then the full size, high res version of the image is displayed. Tapping on the full size image reverses the transitions and removes the new views from the view hierarchy. I want users to also be able to press the BACK key to reverse the image transitions. However, I can't seem to catch the KeyEvent. This is what I'm trying at the moment: // Set a click listener on the image to reverse everything frameView.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { zoomOut(); // This works fine } }); // Set the focus onto the frame and then set a key listener to catch the back buttons frameView.setFocusable(true); frameView.setFocusableInTouchMode(true); frameView.requestFocus(); frameView.setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { // The code never even gets here !!! if(keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) { zoomOut(); return true; } return false; } });

  • ItemUpdating called twice after ItemAdded in event receiver

    - by Jason
    I've created an event receiver to handle the ItemAdded and ItemUpdating events on a document library in SharePoint 2010. I've encountered a problem where when I add a document to the library (e.g. by saving it back from Word) the ItemAdded method is correctly called however this is then followed by two calls to ItemUpdating. I have removed all code from my handlers to ensure that it's not something I'm doing inside that is causing the problem. They literally look like: public override void ItemUpdating(SPItemEventProperties properties) { } public override void ItemAdded(SPItemEventProperties properties) { } Does anyone have a solution to this issue? Here is my elements.xml file for the event receiver: <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <Receivers ListTemplateId="101"> <Receiver> <Name>DocumentsEventReceiverItemUpdating</Name> <Type>ItemUpdating</Type> <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly> <Class>My.Namespace.DocumentsEventReceiver</Class> <SequenceNumber>10000</SequenceNumber> <Synchronization>Synchronous</Synchronization> </Receiver> <Receiver> <Name>DocumentsEventReceiverItemAdded</Name> <Type>ItemAdded</Type> <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly> <Class>My.Namespace.DocumentsEventReceiver</Class> <SequenceNumber>10000</SequenceNumber> <Synchronization>Synchronous</Synchronization> </Receiver> </Receivers> </Elements>

  • Lock thread using somthing other than a object

    - by Scott Chamberlain
    when using a lock does the thing you are locking on have to be a object. For example is this legal static DateTime NextCleanup = DateTime.Now; const TimeSpan CleanupInterval = new TimeSpan(1, 0, 0); private static void DoCleanup() { lock ((object)NextCleanup) { if (NextCleanup < DateTime.Now) { NextCleanup = DateTime.Now.Add(CleanupInterval); System.Threading.ThreadPool.QueueUserWorkItem(new System.Threading.WaitCallback(cleanupThread)); } } return; } EDIT-- From reading SLaks' responce I know the above code would be not valid but would this be? static MyClass myClass = new MyClass(); private static void DoCleanup() { lock (myClass) { // } return; }

  • svg mouseup event not fired in IE9, unless the debugger is open

    - by Roberto Lupi
    I am using d3 to build a simple chart that the user can edit interactively with the mouse. It works on in all modern common browser (Chrome, Firefox, Safari), except for Internet Explorer 9 where I can start to drag an item but I never get the mouseup event. The strangest bit is that, if I open the debugger, the page works percetly on Internet Explorer 9 as well. My code looks like this: item.append("svg:circle") .attr("class", "handle") .attr("opacity",0.5) .attr("stroke","gray") .attr("cx", bx(0.5)-bx(0)) .attr("r", 10) .style("cursor", "crosshair") .style("pointer-events", "all") .call(d3.behavior.drag() .on("dragstart", function() { dragTarget = d3.select(this); }) .on("drag", function() { this.parentNode.appendChild(this); // put us on the front, not really needed var dragTarget = d3.select(this); dragTarget .attr("cy", function() { return d3.event.dy + parseInt(dragTarget.attr("cy"))}); }) .on("dragend", function(d, i) { newY = parseInt(d3.select(this).attr("cy")); newValue = y.invert(newY); var serieNo = this.__data__.serieNo; console.log([serieNo+1,i+1]); data[serieNo+1][i+1] = newValue; updateBarChart(); onchange(); }) );

  • OpenThread() through diiferent thread numbers ?

    - by user354641
    Hi there . I'm confusing about opening different threads with OpenThread Function and examining them with NtQueryInformationThread native function . I have no problem with NtQueryInformationThread & I can examine them finely. the problem is I don't know how to loop through different number of threads using OpenThread (with SetDebugPrivilege Consideration) . suppose we have different threads from number 5100 to 5200 & we want to examine them sequentially : for example 5100, 5101, 5102, 5103, 5104, 5105 ... 5200 ... . I don't know how to use OpenThread Function in delphi in right way ... . I'm using this syntax & I found it wrong : OpenThread(THREAD_ALL_ACCESS,false,(DWORD)5100) . if anyone could guide me how to use OpenThread though different number of threads it would be great . thanks alot .

  • How do I know if a boost thread is done ?

    - by jules
    I am using boost::thread to process messages in a queue. When a first message comes I start a message processing thread. When a second message comes I check if the message processing thread is done. if it is done I start a new one if it is not done I don nothing. How do I know if the thread is done ? I tried with joinable() but it is not working, as when the thread is done, it is still joinable. I also tried to interrupt the process at once, and add an interruption point at the end of my thread, but it did not work. Thanks

  • XNA Multi-Thread Jitters

    - by Ice Phoenix
    Hi guys, brand new question. Just implemented multi-threading into my XNA game as it was unable to keep up with using 1 processor. MT is all implemented fine and everything, however the player seems to jitter all over the spot every now and then. I originally thought it was a loss of data between the update and render, but even when i did the player update in the render it did the same thing. It's not a memory/processor issue as i'm no where near maxing out my RAM or processors. It's strange aswell because none of the other entities in the game seem to have any of these issues. Any ideas at all??

  • JDBC Lock a row using SELECT FOR UPDATE, doesn't work

    - by Rachid
    I am having issues with MySQL's SELECT .. FOR UPDATE, here is the query I am trying to run: SELECT * FROM tableName WHERE HostName='UnknownHost' ORDER BY UpdateTimestamp asc limit 1 FOR UPDATE After this, the concerned thread will do an UPDATE and change the HostName, which is then it should unlock the row. I am running a multi-threaded java application, so 3 threads are running this SQL statement, but when thread 1 runs this, it doesn't lock its results from thread 2 & 3. Therefore threads 2 & 3 are getting the same results and they could update the same row. Also each thread is on its own mysql connection. I'm using Innodb, with transaction-isolation = READ-COMMITTED, and the Autocommit is off before executing the select for update may I miss something? OR perhaps there is a better solution? Thanks a lot. Code : public BasicJDBCDemo() { Le_Thread newThread1=new Le_Thread(); Le_Thread newThread2=new Le_Thread(); newThread1.start(); newThread2.start(); } Thread : class Le_Thread extends Thread { public void run() { tring name = Thread.currentThread().getName(); System.out.println( name+": Debut."); long oid=Util.doSelectLockTest(name); Util.doUpdateTest(oid,name); } } Select : public static long doSelectLockTest(String threadName) { System.out.println("[OUTPUT FROM SELECT Lock ]...threadName="+threadName); PreparedStatement pst = null; ResultSet rs=null; Connection conn=null; long oid=0; try { String query = "SELECT * FROM table WHERE Host=?

  • Help me find article on Multi-threading and Event Handling in Java

    - by JDR
    I once read an article on how to properly write event handlers for multi-threading in Java, but I can't for the life of me find it anymore. It described the pitfalls and potentials for deadlocks that can occur when firing events (not Swing events mind you, but general events like model update notifications). To clarify, the situation would be as such: // let's say this is code from an MVC model somewhere public void setSomeProperty(String myProperty){ if(!this.myProperty.equals(myProperty)){ this.myProperty = myProperty; fireMyPropertyChangedEvent(...); } } The article described how passing control to arbitrary external listener code was a potential cause for deadlock. I now find myself in a situation where I need to fire such events in a multithreaded environment and I would very much like to read the article again to see what it has to say before I continue. Does anyone know the article I'm referring to? I believe it came as a (fairly short) PDF. It started off with an initial naive implementation and incrementally pointed out flaws and improved upon it. It ended with a sort of final proper-way-to-fire-multithreaded-events. I've searched endlessly in my browse history and on google, but all I could find were endless amounts topics on Swing event dispatch threads. Thank you.

  • Dynamic control click event not firing properly

    - by Wil
    I'm creating a next/previous function for my repeater using pageddatasource. I added the link button control dynamically in my oninit using the following code. LinkButton lnkNext = new LinkButton(); lnkNext.Text = "Next"; lnkNext.Click += new EventHandler(NextPage); if (currentPage != objPagedDataSource.PageCount) { pnlMain.Controls.Add(lnkNext); } So in my initial page_load, the next link comes up fine. There are 5 pages in my objPagedDataSource. currentPage variable is 1. The "NextPage" event handler looks like this public void NextPage(object sender, EventArgs e) { if (HttpContext.Current.Request.Cookies["PageNum"] == null) { HttpCookie cookie = new HttpCookie("PageNum"); cookie.Value = "1"; } else { HttpCookie cookie = HttpContext.Current.Request.Cookies["PageNum"]; cookie.Value = (Convert.ToInt32(cookie.Value) + 1).ToString(); } this.BindRepeater(); } So I am incrementing the cookie I am using to track the page number and then rebinding the repeater. Here is the main issue. The first time I click Next, it works, it goes to Page 2 without any problems. When on Page 2, I click Next, it goes back to Page 1. Seems like the Next event is not wiring up properly. Not sure why, any ideas?

  • Firing PropertyChanged event in a complex, nested type in WPF

    - by John
    Hey I have a question about the PropertyChanged vent firing in WPF whne it is used in a complex type. I have a class called DataStore and a list of Departments (an ObservableCollection), and each department again has a list of Products. Properties in the Product class that are changed also affect properties in the Department and DataStore class. How does each Product notify the Department it belongs to, and the DataStore (which is the mother class of all) that one or more of its properties have changed their values? Example: a product has a property NumberSoldToday and is bound. The Department has a property called TotalNumberOfProductsSold: public int TotalNumberOfProductsSold { get { int result = 0; foreach(Product p in this.products) result += p.NumberSoldToday; return result; } } And the data store has a property TotalProductsSold (for all departments): public int TotalProductsSold { get { int result = 0; foreach(Product p in this.deparments) result += p.TotalNumberOfProductsSold; return result; } } If all these properties are bound, and the innermost property changes, it must somehow notify that the value of the other 2 changed as well. How? The only way I can see this happening is to hook up the PropertyChanged event in each class. Th event must also fire when deleting, adding to the collection of products and deparments, respectively. Is there a better, more clever way to do this?

  • Chat app vs REST app - use a thread in an Activity or a thread in a Service?

    - by synic
    In Virgil Dobjanschi's talk, "Developing Android REST client applications" (link here), he said a few things that took me by surprise. Including: Don't run http queries in threads spawned by your activities. Instead, communicate with a service to do them, and store the information in a ContentProvider. Use a ContentObserver to be notified of changes. Always perform long running tasks in a Service, never in your Activity. Stop your Service when you're done with it. I understand that he was talking about a REST API, but I'm trying to make it fit with some other ideas I've had for apps. One of APIs I've been using uses long-polling for their chat interface. There is a loop http queries, most of which will time out. This means that, as long as the app hasn't been killed by the OS, or the user hasn't specifically turned off the chat feature, I'll never be done with the Service, and it will stay open forever. This seems less than optimal. Long question short: For a chat application that uses long polling to simulate push and immediate response, is it still best practice to use a Service to perform the HTTP queries, and store the information in a ContentProvider?

  • WCF methods sharing a dictionary

    - by YeomansLeo
    I'm creating a WCF Service Library and I have a question regarding thread-safety consuming a method inside this library, here is the full implementation that I have until now. namespace WCFConfiguration { [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Single)] public class ConfigurationService : IConfigurationService { ConcurrentDictionary<Tuple<string,string>, string> configurationDictionary = new ConcurrentDictionary<Tuple<string,string>, string>(); public void Configuration(IEnumerable<Configuration> configurationSet) { Tuple<string, string> lookupStrings; foreach (var config in configurationSet) { lookupStrings = new Tuple<string, string>(config.BoxType, config.Size); configurationDictionary.TryAdd(lookupStrings, config.RowNumber); } } public void ScanReceived(string boxType, string size, string packerId = null) { } } } Imagine that I have a 10 values in my configurationDictionary and many people want to query this dictionary consuming ScanReceived method, are those 10 values be shared for each of the clients that request ScanReceived? Do I need to change my ServiceBehavior? The Configuration method is only consumed by one person by the way.

  • Flash: How to dispatch a click event at the top of a loaded .swf?

    - by Myk
    So I'm trying to build a tool that will allow me and other users to all open the same .swf, and then I as the Admin user am able to interact with mine while they all see my mouse movements and button clicks etc on theirs. I'm using BlazeDS to manage this and I'm getting data sent back and forth etc - no difficulties there. The issue I'm running into is this: In an "Admin" instance, I click a button. I capture that X and Y, then tell Blaze to tell my clients to dispatch a Click event at that X and Y. On my client side, I get that data and dispatch a Click event at that X and Y - but the click is actually caught at the stage level. The click on my client side takes place UNDER all of my buttons and other content - so the whole thing fails. Does this make sense? Is there a way to tell it to start the click event at the top?
