  • Swing invokeLater never shows up, invokeAndWait throws error. What can I do?

    - by Geo
    I have this code: try { SwingUtilities.invokeAndWait(new Runnable() { public void run() { try { dialog.handleDownload(); } catch (IOException io) { io.printStackTrace(); } } }); } catch(Exception io) { io.printStackTrace(); } in the handleDownload I'm reading an inputstream, calculating a progress bar's value, and setting it to that. So, when I click a button, a new JFrame opens up and does all the stuff I wrote above. If I have the dialog.handleDownload by itself ( in no SwingUtilities method ), it freezes until the operation is finished. If I add it in a invokeLater it's closed very fast ( I can't see anything, and the operation is not finished ). If I add it in a invokeAndWait I get the invokeAndWait cannot be called from the event dispatcher thread error. What should I do?

  • IDL-like parser that turns a document definition into powerful classes?

    - by paniq
    I am looking for an IDL-like (or whatever) translator which turns a DOM- or JSON-like document definition into classes which are accessible from both C++ and Python, within the same application expose document properties as ints, floats, strings, binary blobs and compounds: array, string dict (both nestable) (basically the JSON type feature set) allow changes to be tracked to refresh views of an editing UI provide a change history to enable undo/redo operations can be serialized to and from JSON (can also be some kind of binary format) allow to keep large data chunks on disk, with parts only loaded on demand provide non-blocking thread-safe read/write access to exchange data with realtime threads allow multiple editors in different processes (or even on different machines) to view and modify the document The thing that comes closest so far is the Blender 2.5 DNA/RNA system, but it's not available as a separate library, and badly documented. I'm most of all trying to make sure that such a lib does not exist yet, so I know my time is not wasted when I start to design and write such a thing. It's supposed to provide a great foundation to write editing UI components.

  • How do I run modals windows from code with cocoa?

    - by Leandro
    Hi,everybody I`m trying to run a window as modal directly from the code. My program starts and a main NSWindows is showed.A thread still running to see if the user has a valid distribution. if he doesn't I need to run a modal.I mean, I have no buttons clicked in the interface.I've designed a NSWindow on the interface builder for a password set, and I want to call it only when my validation is not successful. I have tested and realized that these methods which are responsible for modal windows running only work in a IBAction environment. //This doesn't work -(void) showPasswordWindow { [NSApp runModalForWindow:[self window]]; } //this works But its not useful for me =( - (IBAction) passwordWindowButton:(id)sender { [NSApp runModalForWindow:[self window]]; } Please, help this newbie =)

  • Is select() Ok to implemnet single socket read/write timeout ?

    - by chmike
    I have an application processing network communication with blocking calls. Each thread manages a single connection. I've added a timeout on the read and write operation by using select prior to read or write on the socket. Select is known to be inefficient when dealing with large number of sockets. But is it ok, in term of performance to use it with a single socket or are there more efficient methods to add timeout support on single sockets calls ? The benefit of select is to be portable.

  • Alternatives to FastDateFormat for efficient date parsing?

    - by Tom Tucker
    Well aware of performance and thread issues with SimpleDateFormat, I decided to go with FastDateFormat, until I realized that FastDateFormat is for formatting only, no parsing! Is there an alternative to FastDateFormat, that is ready to use out of the box and much faster than SimpleDateFormat? I believe FastDateFormat is one of the faster ones, so anything that is about as fast would do. Just curious , any idea why FastDateFormat does not support parsing? Doesn't it seriously limit its use? Thanks! EDIT Holy crap, I just left a comment and that literally REMOVED a good answer! This appears a serious bug on stackoverflow!

  • Wait window in a windows application

    - by Vinodtiru
    I basically need to show a wait window to the user. For this i have put two seperate window forms in the application. the first form is the main form with a button. The second one is a empty one with just a label text. On click of the button in Form1 i do the below Form2 f = new Form2(); f.Show(); Thread.Sleep(2000); f.Close(); My idea here is to show the wait window to the user for 2 second. But when i do this the Form 2 is not completely loaded because of which the label in it is blank. Please let me know your inputs on this.

  • OpenGL in Visual studio - Issues with GLEW

    - by BalsamicVinegar
    I'm currently following the openglbook.com tutorials (set up) (Tutorial) and have run into an issue fairly early on. I'm getting the following two errors: 1>main.obj : error LNK2019: unresolved external symbol __imp__glewGetErrorString@4 referenced in function _Initialize 1>main.obj : error LNK2019: unresolved external symbol __imp__glewInit@0 referenced in function _Initialize I have downloaded and compiled freeglut 2.8.0 as well as the glew 1.9.0 binaries. I have copied the libs and includes to C:\Program Files (x86)\Microsoft SDKs\Windows\v6.0A\Lib and Include respectively. The Lib and Include paths have also been added to my project properties under Additional Library/Include directories. I have also defined glew32.lib and freeglut.lib in my linker-Input-Additional dependencies. I have included and at the top of my main file. What am I missing? Every other thread I've found has been solved by adding the directories to the project properties. Does anyone have any ideas?

    - by Bobb
    Say I have simple LINQ extenstion: var filtered = data.Where(i => i.Count > 0); I know that this will not evaluated unless I start to use filtered i.e. foreach(DataItem i in filtered) ... However I need to create cloned version of data and release data as soon as possible. data can be changed in other thread so I want to get immediate snapshot of it. How can I force filtered to be evaluated immediately?

  • Show composition/aggregation/association relations between objects in Visual Paradigm UML diagrams?

    - by ajsie
    I have Netbeans installed with Visual Paradigm plugin. I have converted my php code into UML diagrams (modeling - instant reverse). I can see relations (drawn lines) between superclass and subclasses. However, i cannot see relations between objects inside objects (composition/aggregation/association)? The code looks like: class Thread { private $tag = ''; public function __construct($tagObject) { $this->tag = $tagObject; } } I know its possible using Java cause i've read about it. Im using PHP, is this still possible?

  • SQL query help - merge a value to all rows in a column

    - by Tommy
    I'm trying to migrate a site from a joomla system to a drupal. The problem is that drupal needs filename and sourcepath in the same row, but joomla only has filename. I'm looking for a way to add sourcepath before the filename in all the rows in that column. I'm figuring it's the UPDATE statement that I should use, but I can't figure out how to construct the query. There's a person with a similar problem here, but I don't find the answers in that thread helpful to my problem: http://www.daniweb.com/forums/showth...t+value&page=2 Any suggestions?

  • How can I use multithreading in a Windows Forms application to update a progress bar?

    - by Steve Syfuhs
    There are two objects. The Windows Form with a button and a progress bar, and another object that handles an algorithm. In the algorithm object there is an event, and a property. The event is ProgressChanged, and the property is Progress (which is an int). In the calling window, the button starts off a set of steps in the algorithm object. As each step (or substeps) occurs, the ProgressChanged event fires, and in the window there is an event handler that essentially increments the progress bar relative to the Progress property. The problem I am running into is that because the algorithm has a possibility (and high liklihood) of running a relatively long time, I need to move it into it's own background thread and push the event back up to the window. My issue is that I'm not completely sure what I'm doing when it comes to multi-threading. I've looked at Control.Invoke and I'm a little lost. Can someone point me in the right direction?

  • Endless saving of CoreData Context

    - by Robert
    Sometimes I noticed that a 'save:' operation an a ManagedObjectContext never returns and consumes 100% CPU. I'm using an SQL Store in a GarbageCollected environment (Mac OS X 10.6.3). The disk activity shows about 700 KB/s writing. While having a look at the folder that contains the sqlite database file the "-journal" file appears and disappears, appears and disappears, ... This is part of the call graph from the process analysis: 2203 -[NSManagedObjectContext save:] 1899 -[NSPersistentStoreCoordinator(_NSInternalMethods) executeRequest:withContext:] 1836 -[NSSQLCore executeRequest:withContext:] 1836 -[NSSQLCore saveChanges:] 1479 -[NSSQLCore performChanges] ... 335 -[NSSQLCore recordChangesInContext:] ... 20 -[NSSQLCore rollbackChanges] ... 2 -[NSSQLCore prepareForSave:] ... 62 -[NSPersistentStoreCoordinator(_NSInternalMethods) _checkRequestForStore:originalRequest:andOptimisticLocking:] ... 1 -[NSPersistentStore(_NSInternalMethods) _preflightCrossCheck] ... 184 -[NSMergePolicy resolveConflicts:] ... 120 -[NSManagedObjectContext(_NSInternalChangeProcessing) _prepareForPushChanges:] ... Everything a happening in the main GUI thread. Any ideas what I can to do to resolve the problem?

  • Possible to implement an IsViewPortVisible dependencyproperty for an item in an ItemsControl?

    - by Matt H.
    I need to enable/disable spell checking in a richtextbox in an ItemsControl, based on whether the RichTextBox is visible in the ItemsControl's Scrollviewer. I think the route is to implement an IsViewPortVisible dependency property and wire an event handler for a changed event... I found this article that describes the lengthy process for determining if an item is in the viewport: http://social.msdn.microsoft.com/Forums/en/wpf/thread/e6ccfec3-3dc0-4702-9d0d-1cfa55ecfc90 Any ideas on where to start? I'm familiar with implementing my own dependency property for the sake of simple bindings (integers, strings, etc...). I have no idea how to undergo something like this though) This is the end result I'm hoping for: <DataTemplate> <Grid> ...Stuff in the Grid <local:CustomRichTextBox SpellCheck.IsEnabled={Binding RelativeSource={RelativeSource Self}, Path=IsViewPortVisible}/> </Grid> </DataTemplate> Help will be EXTREMELY appreciated... you'll be saving me about 500MB in memory consumption while the program is running!!!! :)

  • Jmeter Query new user

    - by Sri
    First of all apologies for the below question. Am from a Testing background for the past 8 years and very novice to Jmeter. I went through the Jmeter site, and ran a sample recording using the jmeter.apache.org site and it went fine. I want to test my knowledge and understanding. So, I did the following way. Created a thread group. Added a config element HTTP Default Requests with server name as mail.google.com. Added a Sampler as HTTP request, set the METHOD to POST and gave the username and password, and i ran the test. When i see the Results Viewer, i could see the login page of gmail, I need to know how to pass my username and password and simulate the clicking of Submit button and getting the next page. Please help, am very new and will really appreciate if it's explained as simple as possible.

  • executorservice to read data from database in chuncks and run process on them

    - by TazMan
    I'm trying to write a process that would read data from a database and upload it onto a cloud datastore. How can I decide the partition strategy of the data? I want to query the table in chunks and process each chunk in 10 threads. Each thread basically will send the data to an individual node on a 10 node cluster on the cloud.. Where in the below multi threading code will the dataquery to extract and send 10 concurrent requests for uploading data to cloud would be? public class Caller { public static void main(String[] args) { ExecutorService executor = Executors.newFixedThreadPool(10); for (int i = 0; i < 10; i++) { Runnable worker = new DomainCDCProcessor(i); executor.execute(worker); } executor.shutdown(); while (!executor.isTerminated()) { } System.out.println("Finished all threads"); } }

  • FTP - way to programatically determine time remaining or bytes transfered?

    - by ciaranarcher
    Hi all I want to make an FTP connection (ideally using Coldfusion 8, but Java is fine too) that will copy a file to a remote server. Crucially however, I want to know how many bytes have been transferred so I can give some feedback to the user. Is this possible, and if so what FTP API would you recommend as I understand the Sun implementation may be a bit lacking. Thanks in advance! PS: I could have another process/thread poll the file size on the destination machine via a web service call while the file is being transferred but it's not ideal. Getting it through FTP API would be the neatest solution.

  • Queued WCF Service which processes every X seconds

    - by Jeff Windsor
    I need to create a service which can process queued requests on a configured time interval. For example go to the web and get financial data from a site the requires we limit requests to once per second. I am new to WCF and I am not sure if (1) WCF with MSMQ a proper choice for implementing this? and (2) if so what is the best mechanism for enforcing the interval? a thread wait? a timer (not sure how that would work).

  • Threaded application sleeps with other application

    - by DeeD
    I have a weird problem with my threaded software. I start 2 instances of the software. Each instance has 2 threads, one thread creates a socket to use, and the other one is uses the socket for communication. When one of the threads in one instance calls sleep(3), the other threads in the the other instance sleeps too. And the weirdest thing is that when I rebooted the computer, it works the first time, but after trying a second time, it sleeps like described. How is this possible? Is it using some shared resource?

  • Commands implicitly threaded in Makefiles ?

    - by apple92
    Hi, I have a "super" makefile which launches two "sub" make file: libwebcam: @echo -e "\nInvoking libwebcam make." $(MAKE) -C $(TOPDIR)/libwebcam uvcdynctrl: @echo -e "\nInvoking uvcdynctrl make." $(MAKE) -C $(TOPDIR)/uvcdynctrl uvcdynctrl uses libwebcam... I noticed that those two builds are launched as separate threads by make ! Thus sometimes the lib is not available when uvcdynctrl starts being built, and I get errors. By default, make should not launch commands as threads since this is available only through -j (number of jobs) and, according to the make manual, there is no thread by default. I run this on an Ubuntu. Did someone face the same issue ? Apple92

  • How do I determine darker or lighter color variant of a given color?

    - by Nidonocu
    Given a source color of any hue by the system or user, I'd like a simple algorithm I can use to work out a lighter or darker variants of the selected color. Similar to effects used on Windows Live Messenger for styling the user interface. Language is C# with .net 3.5. Responding to comment: Color format is (Alpha)RGB. With values as bytes or floats. Marking answer: For the context of my use (a few simple UI effects), the answer I'm marking as accepted is actually the most simple for this context. However, I've given up votes to the more complex and accurate answers too. Anyone doing more advanced color operations and finding this thread in future should definitely check those out. Thanks SO. :)

  • What is the absolute fastest way to implement a concurrent queue with ONLY one consumer and one producer?

    - by JohnPristine
    java.util.concurrent.ConcurrentLinkedQueue comes to mind, but is it really optimum for this two-thread scenario? I am looking for the minimum latency possible on both sides (producer and consumer). If the queue is empty you can immediately return null AND if the queue is full you can immediately discard the entry you are offering. Does ConcurrentLinkedQueue use super fast and light locks (AtomicBoolean) ? Has anyone benchmarked ConcurrentLinkedQueue or knows about the ultimate fastest way of doing that? Additional Details: I imagine the queue should be a fair one, meaning the consumer should not make the consumer wait any longer than it needs (by front-running it) and vice-versa.

  • Project works in eclipse but not when exported

    - by Mike
    I wrote an application that uses GraphViz to generate some graphs as .gif's according to the DOT syntax. When I run from Eclipse the images are generated fine but when I export it as a jar the images are created but there is no data in them. When I view them in Microsoft Picture Viewer its just the red X. It was working as an exported jar until I put the picture generation in its own thread. I can't seem to figure out whats going on here. Are there any problems exporting multi-threaded projects? Any one have any ideas? Thanks
