• compile error: The import xxxx cannot be resolved

  - by Zachary

  I am developing a Java project using Eclipse. The project uses another project called engine, which I have added in my project build-path. As I need to call a dabo class, called House, in one of my project class, named Window, I have used the following code as usual: import ee.asus.kernel.House; I got however the following error in compiling time: Exception in thread "main" java.lang.Error: Unresolved compilation problems: The import ee cannot be resolved House cannot be resolved to a type House cannot be resolved to a type House cannot be resolved to a type at main.ee.asus.GUI.FrameWindow.Window.<init>(Window.java:10) at main.ee.asus.GUI.StartApplication.main(StartApplication.java:13) It's worth to point out that my prject and the dabo project use the same directory/packages names. Does anyone have a clue where the error may be?

• Disabling multitasking on iPhone 3GS using UIApplicationExitsOnSuspend not working

  - by NobleK

  Hello I am developing an iPhone app where I don’t want/need the multitasking capability and I want my app to initiate every time I open it. I have set the UIApplicationExitsOnSuspend property in the info.plist and it does work when I test it on my iPhone 4 and in the simulator (which is also an ”iPhone 4”). The app calls applicationDidEnterBackground followed by applicationWillTerminate. However, when testing it on my wifes iPhone 3GS the property seems to be completely ignored and the program gets suspended/resumed. Both phones are running iOS 4.2.1. Someone has also confirmed this issue in another thread, with no solutions unfortunately: iPhone: how to test if UIApplicationExitsOnSuspend is working? Is there something I am missing to make this work? Any other ways to accomplish this? Thanx in advance

• iPhone - making the crash information more specific

  - by Digital Robot

  I have an app that is crashing at some point. Even with NSZombieEnabled turned on, the only thing I see is this message on the console: : * -[CFRunLoopTimer release]: message sent to deallocated instance 0x4cb34e0 but as the app is crashed, there's no way to know what object is this and the thread overview is not helping that much. #0 0x34a80466 in objc_msgSend #1 0x357e53c8 in CFRelease #2 0x357f3976 in __CFTypeCollectionRelease #3 0x3580c0b6 in __CFSetReleaseValue #4 0x357e6a5c in __CFBasicHashDrain #5 0x357e6900 in __CFSetDeallocate #6 0x357e54b6 in _CFRelease #7 0x357e53dc in CFRelease #8 0x3580c098 in -[__NSCFSet release] #9 0x3570f3be in -[_NSFaultingMutableSet dealloc] #10 0x3570f260 in -[_NSFaultingMutableSet release] #11 0x35702480 in -[NSManagedObject(_NSInternalMethods) _clearRawPropertiesWithHint:] #12 0x357022a8 in -[NSFaultHandler turnObject:intoFaultWithContext:] #13 0x35703dc0 in -[NSManagedObject dealloc] #14 0x356eab34 in -[_PFManagedObjectReferenceQueue _processReferenceQueue:] #15 0x357127d6 in _performRunLoopAction #16 0x3580ac58 in __CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION__ #17 0x3580aacc in __CFRunLoopDoObservers #18 0x358020ca in __CFRunLoopRun #19 0x35801c86 in CFRunLoopRunSpecific #20 0x35801b8e in CFRunLoopRunInMode #21 0x320c84aa in GSEventRunModal #22 0x320c8556 in GSEventRun #23 0x341dc328 in -[UIApplication _run] #24 0x341d9e92 in UIApplicationMain #25 0x00002e02 in main at main.m:14 it appears to be something related to core data, but knowing that doesn't help that much, because the app is all core data based and it crashes when I am not doing anything related to core data. is there a way to make the debugger more specific? thanks

• What's the best way to cancel an asynchronous WCF request?

  - by Pwninstein

  (Assuming a WCF method called "MyFunction") Currently, to support canceling a WCF request, I'm using the BeginMyFunction/EndMyFunction methods generated by svcutil (and handling an isCanceled flag when dispatching the results to the main thread). I'd like to use the MyFunctionAsync method (and hooking into MyFunctionAsyncCompleted event instead) for async calls instead of Begin/End. What is the best/supported way to handle canceling WCF requests if using MyFunctionAsyncCompleted, and still ensuring that the event doesn't get fired on a page that's no longer loaded (i.e. page navigation within a frame). Thanks!

• WPF DataGrid adding extra "ghost" row

  - by hs2d

  Hei, In my application i'm using DataGrid to show some data. To get everything working with threading i'm using AsyncObservableCollection as DataContext of DataGrid. When my application starts it looks for files in some folders and updates AsyncObservableCollection. Now here's where things go bad, when i start the application for some reason i get 2 rows with same data in DataGrid even if there is one item in collection. If i add a delay(Thread.Sleep() 50ms minimum) before executing loading files method then DataGrid show everything correctly (no extra row). Have anybody encountered something similar or is there something else i should try? Thanks in advance!

• Avoiding dog-piling or thundering herd in a memcached expiration scenario

  - by Quintin Par

  I have the result of a query that is very expensive. It is the join of several tables and a map reduce job. This is cached in memcached for 15 minutes. Once the cache expires the queries are obviously run and the cache warmed again. But at the point of expiration the thundering herd problem issue can happen. One way to fix this problem, that I do right now is to run a scheduled task that kicks in the 14th minute. But somehow this looks very sub optimal to me. Another approach I like is nginx’s proxy_cache_use_stale updating; mechanism. The webserver/machine continues to deliver stale cache while a thread kicks in the moment expiration happens and updates the cache. Has someone applied this to memcached scenario though I understand this is a client side strategy? If it benefits, I use Django.

• Optimizing Dijkstra for dense graph?

  - by Jason

  Is there another way to calculate the shortest path for a near complete graph other than Dijkstra? I have about 8,000 nodes and about 18 million edges. I've gone through the thread "a to b on map" and decided to use Dijkstra. I wrote my script in Perl using the Boost::Graph library. But the result isn't what I expected. It took about 10+ minutes to calculate one shortest path using the call $graph-dijkstra_shortest_path($start_node,$end_node); I understand there are a lot of edges and it may be the reason behind the slow running time. Am I dead in the water? Is there any other way to speed this up?

• custom progress bar in net compact framework

  - by amolitrivedi

  Hi all, I want to have my own progress bar in .net compact framework, instead of default wait cursor. I have tried with a form, having only a progress bar, and showing and hiding the form when I want to show some background activity running, but that does not update the progress bar. I have found out that it needs to be on different thread. I am quite weak at threads, I cant get it working. Please help me out. Thanks in advance.

• android phone's scroll ball, D-Pad not working

  - by user270811

  hi, i have a Cliq and a MyTouch phone. i am writing a game that requires a fire button. on the cliq, it's the center of the D-Pad, and on the MyTouch, the scroll ball. i am handling the onKeyDown events via a separate thread. it all works until i press the button too many times, meaning the key down event is no longer fired off. if i press the D-Pad down or scroll the ball down, then the fire button works again. i can only guess that maybe the message queue within the OS is full, therefore the fire button temporarily malfuntions. can someone help me? thanks.

• Have threads run indefinitely in a java application

  - by TP

  I am trying to program a game in which I have a Table class and each person sitting at the table is a separate thread. The game involves the people passing tokens around and then stopping when the party chime sounds. how do i program the run() method so that once I start the person threads, they do not die and are alive until the end of the game One solution that I tried was having a while (true) {} loop in the run() method but that increases my CPU utilization to around 60-70 percent. Is there a better method?

• How to abort iPhone's NSXMLParser wait

  - by Wayne Lo

  When init the NSXLParser as below: NSXMLParser* xmlParser=[[NSXMLParser alloc] initWithContentsOfURL:[NSURL URLWithString:urlstring]]; if the server is down, it will wait for quite some time before the thread returns. It is really annoying even if I exit the application and restart the application, it will continue to wait with a black screen until it times out. How to I abort the init? Is there a better way to check whether the server is up before calling the parser? Thanks for helping.

• Ruby: would using Fibers increase my DB insert throughput?

  - by Zombies

  Currently I am using Ruby 1.9.1 and the 'ruby-mysql' gem, which unlike the 'mysql' gem is written in ruby only. This is pretty slow actually, as it seems to insert at a rate of almost 1 per second (SLOOOOOWWWWWW). And I have a lot of inserts to make too, its pretty much what this script does ultamitely. I am using just 1 connection (since I am using just one thread). I am hoping to speed things up by creating a fiber that will create a new DB connection insert 1-3 records close the DB connection I would imagine launching 20-50 of these would greatly increase DB throughput. Am I correct to go along this route? I feel that this is the best option, as opposed to refactoring all of my DB code :(

• How do I trigger specific parts of a storyboard in WPF?

  - by George

  I have several grids in my window. I have created a storyboard that moves them left by x pixels when a button is clicked. I want to make it so that when the button is clicked again those grids move another x pixels, however I'm unable to find out how to do this as it's not a common task on tutorials. I have tried creating a second storyboard to do this, however that won't work as then the grids will be back at their starting positions. One solution might be to create a third set of keyframes after the first two sets, and somehow pause the animation when it gets there, and resumes it again when the button is clicked, however I'm not sure how to pause a storyboard when it reaches a keyframe. This would also make reversing the grids difficult (using this approach http://social.msdn.microsoft.com/forums/en-US/wpf/thread/ac54de71-f750-4940-91a2-231810308727/), as I'd like to make another button make the grids go the other way.

• Swing Timer in Conjunction with Possible Long-running Background Task

  - by javacavaj

  I need to perform a task repeatedly that affects both GUI-related and non GUI-related objects. One caveat is that no action should performed if the previous task had not completed when the next timer event is fired. My initial thoughts are to use a SwingTimer in conjunction with a javax.swing.SwingWorker object. The general setup would look like this. class { timer = new Timer(speed, this); timer.start(); public void actionPerformed(ActionEvent e) { SwingWorker worker = new SwingWorker() { @Override public ImageIcon[] doInBackground() { // potential long running task } @Override public void done() { // update GUI on event dispatch thread when complete } } } Some potential issues I see with this approach are: 1) Multiple SwingWorkers will be active if a worker has not completed before the next ActionEvent is fired by the timer. 2) A SwingWorker is only designed to be executed once, so holding a reference to the worker and reusing (is not?) a viable option. Is there a better way to achieve this?

• Help me understand Dispose() implementation code from MSDN

  - by Benny

  the following code is from MSDN: Idisposable pattern protected virtual void Dispose(bool disposing) { // If you need thread safety, use a lock around these // operations, as well as in your methods that use the resource. if (!_disposed) { if (disposing) { if (_resource != null) _resource.Dispose(); Console.WriteLine("Object disposed."); } // Indicate that the instance has been disposed. _resource = null; _disposed = true; } } why the following statement: _resource = null; _disposed = true; are not enclosed by if (disposing) statement block? for me i would probably write like this: if (disposing) { if (_resource != null) { _resource.Dispose(); _resource = null; _disposed = true; } Console.WriteLine("Object disposed."); } anything wrong with my version?

• C# String Resource Values as Enum String Part values?

  - by JL

  Using VS2010 and .net V4.0 I would like to achieve the following: I already have 2 resource files in my project for 2 languages - English and Czech. I must say Resource Management in .net is excellent, I am suprised even to get code completion when implementing a String for example: string desc = Strings.ResourceManagerDesc This gets the string associated with the current culture of the thread. Now I am trying to create an Enum that can have the String portion of the Enum interpreted from the Strings resources. In the following way (This code DOES NOT WORK): public enum DownloadStatus { 1 = Strings.DownloadState_Complete, 2 = Strings.DownloadState_Failed, 3 = Strings.DownloadState_InProgress } This is a made up example, but you can see the point here. Since the above code won't work, is there a best practice way to achieve what I want?

• Storage for large gridded datasets

  - by nullglob

  I am looking for a good storage format for large, gridded datasets. The application is meteorology, and we would prefer a format that is common within this field (to help exchange data with others). I don't need to deal with special data structures, and there should be a Fortran API. I am currently considering HDF5, GRIB2 and NetCDF4. How do these formats compare in terms of data compression? What are their main limitations? How steep is the learning curve? Are there any other storage formats worth investigating? I have not found a great deal of material outlining the differences and pros/cons of these formats (there is one relevant SO thread, and a presentation comparing GRIB and NetCDF).

• audio stream sampling rate in linux

  - by farhan

  Im trying read and store samples from an audio microphone in linux using C/C++. Using PCM ioctls i setup the device to have a certain sampling rate say 10Khz using the SOUND_PCM_WRITE_RATE ioctl etc. The device gets setup correctly and im able to read back from the device after setup using the "read". int got = read(itsFd, b.getDataPtr(), b.sizeBytes()); The problem i have is that after setting the appropriate sampling rate i have a thread that continuously reads from /dev/dsp1 and stores these samples, but the number of samples that i get for 1 second of recording are way off the sampling rate and always orders of magnitude more than the set sampling rate. Any ideas where to begin on figuring out what might be the problem?

• Multi-Threaded Application - Help with some pseudo code!!

  - by HonorGod

  I am working on a multi-threaded application and need help with some pseudo-code. To make it simpler for implementation I will try to explain that in simple terms / test case. Here is the scenario - I have an array list of strings (say 100 strings) I have a Reader Class that reads the strings and passes them to a Writer Class that prints the strings to the console. Right now this runs in a Single Thread Model. I wanted to make this multi-threaded but with the following features - Ability to set MAX_READERS Ability to set MAX_WRITERS Ability to set BATCH_SIZE So basically the code should instantiate those many Readers and Writers and do the work in parallel. Any pseudo code will really be helpful to keep me going!

• Script.PostDeployment.sql not executing in CI build VS 2010

  - by Suirtimed

  I have a database project in VS 2010 (SQL 2008). The local Deploy Solution action works and executes all of the SQL in the Script.PostDeployment.sql file. When I check changes in, the Build Definition for the continuous integration server executes. The database is deployed into the CI environment, but the PostDeployment script doesn't get executed. I wasn't able to find anything specific to this particular scenario. I also expect I'll need to provide additional information unless this is a trivial problem that I missed somewhere. Additional Information: The build is executing vsdbcmd.exe to deploy. The deployment manifest references the PostDeployment.sql file and it's present in the path with the rest of the files. Here is a reference to a thread on social.msdn.microsoft.com regarding this problem.

• Listening to another window resize events in C#

  - by Steve

  Hi all I am implementing a small application (observer) that needs to "attach" itself to the bottom of another window (observed). The latter is not a window inside the application. At this moment I solved by getting the hWnd of the window and querying periodically in a thread the location of the observed window, moving the observer window accordingly. However this is a very inelegant solution. What I would like to do is to listen to the resize event of the observed window so that the observer will react only when necessary. I assume I should use a hook, and I found plenty of ways of doing it, but my lack of knowledge of the C WinAPI is blocking me in understanding which hook I need to create and how (pinvoke/parameters/etc). I'm pretty sure this is quite trivial, and some of you familiar with C/C++ and WinAPI will have the answer ready at hand ;) Thanks

• How to get total cpu usage in Linux (c++)

  - by cz-david

  I am trying to get total cpu usage in %. First I should start by saying that "top" will simply not do, as there is a delay between cpu dumps, it requires 2 dumps and several seconds, which hangs my program (I do not want to give it its own thread) next thing what I tried is "ps" which is instant but always gives very high number in total (20+) and when I actually got my cpu to do something it stayed at about 20... Is there any other way that I could get total cpu usage? It does not matter if it is over one second or longer periods of time... Longer periods would be more useful, though.

• Getting a JFrame's actual current location

  - by Ian Fellows

  Hello community, I am trying to create a (child) JFrame which slides out from underneath one side of a second (parent) JFrame. The goal is to then have the child follow the parent around when it is moved, and respond to resizing events. This is somewhat related to this question. I have tried using a ComponentListener, but with this method the child only moves once the parent has come to a stop, whereas I would like the child to move as the parent is dragged around the screen. Another option I attempted was to start a new refresher thread that continually updated the child's location using getLocation() or getLocationOnScreen(), but the lag was the same as with ComponentListener. Is there a way to get the true actual location of a JFrame even in the midst of a drag? or if not, is there a way to get the effect of a sheet sliding out from underneath and following the Frame around?
