  • Add file using SharpSVN

    - by jan
    Hi, I would like to add all unversioned files under a directory to SVN using SharpSVN. I tried regular svn commands on the command line first: C:\temp\CheckoutDir> svn status -v I see all subdirs, all the files that are already checked in, a few new files labeled "?", nothing with the "L" lock indication C:\temp\CheckoutDir> svn add . --force This results in all new files in the subdirs ,that are already under version control themselves, to be added. I'd like to do the same using SharpSVN. I copy a few extra files into the same directory and run this code: ... using ( SharpSvn.SvnClient svn = new SvnClient() ) { SvnAddArgs saa = new SvnAddArgs(); saa.Force = true; saa.Depth = SvnDepth.Infinity; try { svn.Add(@"C:\temp\CheckoutDir\." , saa); } catch (SvnException exc) { Log(@"SVN Exception: " + exc.Message + " - " + exc.File); } } But an SvnException is raised: SvnException.Message: Working copy 'C:\temp\CheckoutDir' locked SvnException.File: ..\..\..\subversion\libsvn_wc\lock.c" No other svnclient instance is running in my code, I also tried calling svn.cleanup() right before the Add, but to no avail. Since the documentation is rather vague ;), I was wondering if anyone here knew the answer. Thanks in advance! Jan

  • MP3 Decoding on Android

    - by Rob Szumlakowski
    Hi. We're implementing a program for Android phones that plays audio streamed from the internet. Here's approximately what we do: Download a custom encrypted format. Decrypt to get chunks of regular MP3 data. Decode MP3 data to raw PCM data in a memory buffer. Pipe the raw PCM data to an AudioTrack Our target devices so far are Droid and Nexus One. Everything works great on Nexus One, but the MP3 decode is too slow on Droid. The audio playback starts to skip if we put the Droid under load. We are not permitted to decode the MP3 data to SD card, but I know that's not our problem anyways. We didn't write our own MP3 decoder, but used MPADEC (http://sourceforge.net/projects/mpadec/). It's free and was easy to integrate with our program. We compile it with the NDK. After exhaustive analysis with various profiling tools, we're convinced that it's this decoder that is falling behind. Here's the options we're thinking about: Find another MP3 decoder that we can compile with the Android NDK. This MP3 decoder would have to be either optimized to run on mobile ARM devices or maybe use integer-only math or some other optimizations to increase performance. Since the built-in Android MediaPlayer service will take URLs, we might be able to implement a tiny HTTP server in our program and serve the MediaPlayer with the decrypted MP3s. That way we can take advantage of the built-in MP3 decoder. Get access to the built-in MP3 decoder through the NDK. I don't know if this is possible. Does anyone have any suggestions on what we can do to speed up our MP3 decoding? -- Rob Sz

  • How to require fullscreen mode in a jQTouch application?

    - by Christopher Young
    I'm using jQTouch to develop a version of a website optimized for safari on the iphone. The jQTouch demo helpfully shows how to show an "install this" message for users not using full screen mode and hide it for those who are. When in fullscreen mode, the body should have the class "fullscreen." So you can hide the "install this" message for people who have already added your app to their home page by adding this css rule to your stylesheet: body.fullscreen #home .info { display: none; } What I'd like to do is require users to use the app in fullscreen mode only. When viewed from the regular browser, they should only see a message asking them to install the app. That message should of course be hidden otherwise. This ought to be really, really easy, so I must just be missing something obvious. I thought one way to do this would be to simply test for the class "fullscreen" on the body: if it's not there, use goTo to get to another div, or hide the other divs, or something like that. Strangely, however, this doesn't work. As a test, I've still got the original "info" message, as in the jQTouch demo, and it doesn't show up when I launch in fullscreen mode. So the body must have the fullscreen class. And yet I can't find any other trace of it: when I put this alert to test things after the document has loaded, I get nothing when launching in fullscreen mode: alert($("body").attr("class")); I also thought I might test for fullscreen mode by checking for the value of the fullScreen boolean. But this doesn't seem to work either. What am I missing? What is the best way to do this?

  • WCF Ria Services Error : Load operation failed for query 'GetTranslationProgress'

    - by Manoj
    Hello, I am using WCF Ria Services beta in my silverlight application. I have a long running task on the server which keeps writing its status to a database table. I have a "GetTranslationProgress" Ria Service Query method which queries the state to get the status. This query method is called continuously at a regular interval of 5 seconds until a status = Finished or Error is retrieved. In some cases if the task on the server is running for a long duration 2-3 minutes then I receives this error:- Load operation failed for query 'GetTranslationProgress'. The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error. at System.Windows.Ria.OperationBase.Complete(Exception error) at System.Windows.Ria.LoadOperation.Complete(Exception error) at System.Windows.Ria.DomainContext.CompleteLoad(IAsyncResult asyncResult) at System.Windows.Ria.DomainContext.<c_DisplayClass17.b_13(Object ) The error occurs intermittently and I have no idea what could be causing this error. I have checked most of the forums and sites but I have not been able to find out any solution to this issue. Please help.

  • WCF push to client through firewall?

    - by Sire
    See also How does a WCF server inform a WCF client about changes? (Better solution then simple polling, e.g. Coment or long polling) I need to use push-technology with WCF through client firewalls. This must be a common problem, and I know for a fact it works in theory (see links below), but I have failed to get it working, and I haven't been able to find a code sample that demonstrates it. Requirements: WCF Clients connects to server through tcp port 80 (netTcpBinding). Server pushes back information at irregular intervals (1 min to several hours). Users should not have to configure their firewalls, server pushes must pass through firewalls that have all inbound ports closed. TCP duplex on the same connection is needed for this, a dual binding does not work since a port has to be opened on the client firewall. Clients sends heartbeats to server at regular intervals (perhaps every 15 mins) so server knows client is still alive. Server is IIS7 with WAS. The solution seems to be duplex netTcpBinding. Based on this information: WCF through firewalls and NATs Keeping connections open in IIS But I have yet to find a code sample that works.. I've tried combining the "Duplex" and "TcpActivation" samples from Microsoft's WCF Samples without any luck. Please can someone point me to example code that works, or build a small sample app. Thanks a lot!

  • What do you mean by the expressiveness in a programming language?

    - by prosseek
    I see a lot of the word 'expressiveness' when people want to stress one language is better than the other. But I don't see exactly what they mean by it. Is it the verboseness/succinctness? I mean, if one language can write down something shorter than the other, does that mean expressiveness? Please refer to my other question - http://stackoverflow.com/questions/2411772/article-about-code-density-as-a-measure-of-programming-language-power Is it the power of the language? Paul Graham says that one language is more powerful than the other language in a sense that one language can do that the other language can't do (for example, LISP can do something with macro that the other language can't do). Is it just something that makes life easier? Regular expression can be one of the examples. Is it a different way of solving the same problem: something like SQL to solve the search problem? What do you think about the expressiveness of a programming language? Can you show the expressiveness using some code? What's the relationship with the expressiveness and DSL? Do people come up with DSL to get the expressiveness?

  • Lucene.NET 2.9 and BitArray/DocIdSet

    - by Paul Knopf
    I found a great example on grabbing facet counts on a base query. It stores the bitarray of the base query to improve the performance each time the a facet gets counted. var genreQuery = new TermQuery(new Term("genre", genre)); var genreQueryFilter = new QueryFilter(genreQuery); BitArray genreBitArray = genreQueryFilter.Bits(searcher.GetIndexReader()); Console.WriteLine("There are " + GetCardinality(genreBitArray) + " document with the genre " + genre); // Next perform a regular search and get its BitArray result Query searchQuery = MultiFieldQueryParser.Parse(term, new[] {"title", "description"}, new[] {BooleanClause.Occur.SHOULD, BooleanClause.Occur.SHOULD}, new StandardAnalyzer()); var searchQueryFilter = new QueryFilter(searchQuery); BitArray searchBitArray = searchQueryFilter.Bits(searcher.GetIndexReader()); Console.WriteLine("There are " + GetCardinality(searchBitArray) + " document containing the term " + term); The only problem is that I am using a newer version of Lucene.NET (2.9) and Filter.Bits is obsolete. We are told to use DocIdSet instead (rather than BitArray). I cannot found out how to do the bitArray.And(bitArray) with a docIdSet. I looked in reflector and found OpenIdSet which has And operations. Not sure if OpenIdSet is the route to go, I'm just stating. Thanks in advance!

  • Running and managing NSTimer in different NSThread/NSRunLoop

    - by mips
    I'm writing a Cocoa application, with a GUI designed in Interface Builder. I need to schedule background activity (at regular intervals) without blocking the UI, so I run it in a separate thread, like this: - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { [self performSelectorInBackground:@selector(schedule) withObject:nil]; } - (void) schedule { NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init]; NSRunLoop* runLoop = [NSRunLoop currentRunLoop]; timer = [[NSTimer scheduledTimerWithTimeInterval:FEED_UPDATE_INTERVAL target:activityObj selector:@selector(run:) userInfo:nil repeats:YES] retain]; [runLoop run]; [pool release]; } I retain the timer, so I can easily invalidate and reschedule. Problem: I must also fire the run: method in response to GUI events, so it is synchronous (i.e. a "perform activity" button). Like this: [timer fire]; I could do this with performSelectorInBackground too, and of course it doesn't block the UI. But this synchronous firings run in another runloop! So I have no guarantee that they won't overlap. How can I queue all of my firings on the same runloop?

  • Open source GIS tools

    - by TRV_SQL
    Hi I’ve been looking at Open Source GIS tools. In particular MapServer and GeoServer. The problem I’m seeing is that to actually deploy these to the public you can’t use a regular $5/ month (or free) hosting service because you have to install these services on the server in ways that are not accessible in the average hosting scheme. So you either have to use a host that has MapServer installed (many of which look unreliable) or have a dedicated server or VPS. All of these options have a significant cost barrier ($30 - $200/month). I’m just doing this for fun. Are there any free or inexpensive ways to have your GIS services hosted? Or are there any products that install in a way that you don’t need to access the root structure of the server? I have tried OpenLayers and GeoExt but I don’t think a client side option will work for me because of the size of the datasets I am using. My base data will be vector data not WMS data (or something similar). I haven’t tried Google maps yet, but I will be looking into it. Also, any thought on using SVG for GIS purposes? Thanks

  • Need help regarding one LALR(1) parsing.

    - by AppleGrew
    I am trying to parse a context-free language, called Context Free Art. I have created its parser in Javascript using a YACC-like JS LALR(1) parser generator JSCC. Take the example of following CFA (Context Free Art) code. This code is a valid CFA. startshape A rule A { CIRCLE { s 1} } Notice the A and s in above. s is a command to scale the CIRCLE, but A is just a name of this rule. In the language's grammar I have set s as token SCALE and A comes under token STRING (I have a regular expression to match string and it is at the bottom of of all tokens). This works fine, but in the below case it breaks. startshape s rule s { CIRCLE { s 1} } This too is a perfectly valid code, but since my parser marks s after rule as SCALE token so it errors out saying that it was expecting STRING. Now my question is, if there is any way to re-write the production rules of the parser to account for this? The related production rule is:- rule: RULE STRING '{' buncha_replacements '}' [* rule(%2, 1) *] | RULE STRING RATIONAL '{' buncha_replacements '}' [* rule(%2, 1*%3) *] ; One simple solution I can think of is create a copy of above rule with STRING replaced by SCALE, but this is just one of the many similar rules which would need such fixing. Furthermore there are many other terminals which can get matched to STRING. So that means way too many rules!

  • Leopard => Snow Leopard architecture woes with nokogiri / rails

  • What is the worst programming language you ever worked with? [closed]

    - by Ludwig Weinzierl
    If you have an interesting story to share, please post an answer, but do not abuse this question for bashing a language. We are programmers, and our primary tool is the programming language we use. While there is a lot of discussion about the best one, I'd like to hear your stories about the worst programming languages you ever worked with and I'd like to know exactly what annoyed you. I'd like to collect this stories partly to avoid common pitfalls while designing a language (especially a DSL) and partly to avoid quirky languages in the future in general. This question is not subjective. If a language supports only single character identifiers (see my own answer) this is bad in a non-debatable way. EDIT Some people have raised concerns that this question attracts trolls. Wading through all your answers made one thing clear. The large majority of answers is appropriate, useful and well written. UPDATE 2009-07-01 19:15 GMT The language overview is now complete, covering 103 different languages from 102 answers. I decided to be lax about what counts as a programming language and included anything reasonable. Thank you David for your comments on this. Here are all programming languages covered so far (alphabetical order, linked with answer, new entries in bold): ABAP, all 20th century languages, all drag and drop languages, all proprietary languages, APF, APL (1), AS400, Authorware, Autohotkey, BancaStar, BASIC, Bourne Shell, Brainfuck, C++, Centura Team Developer, Cobol (1), Cold Fusion, Coldfusion, CRM114, Crystal Syntax, CSS, Dataflex 2.3, DB/c DX, dbase II, DCL, Delphi IDE, Doors DXL, DOS batch (1), Excel Macro language, FileMaker, FOCUS, Forth, FORTRAN, FORTRAN 77, HTML, Illustra web blade, Informix 4th Generation Language, Informix Universal Server web blade, INTERCAL, Java, JavaScript (1), JCL (1), karol, LabTalk, Labview, Lingo, LISP, Logo, LOLCODE, LotusScript, m4, Magic II, Makefiles, MapBasic, MaxScript, Meditech Magic, MEL, mIRC Script, MS Access, MUMPS, Oberon, object extensions to C, Objective-C, OPS5, Oz, Perl (1), PHP, PL/SQL, PowerDynamo, PROGRESS 4GL, prova, PS-FOCUS, Python, Regular Expressions, RPG, RPG II, Scheme, ScriptMaker, sendmail.conf, Smalltalk, Smalltalk , SNOBOL, SpeedScript, Sybase PowerBuilder, Symbian C++, System RPL, TCL, TECO, The Visual Software Environment, Tiny praat, TransCAD, troff, uBasic, VB6 (1), VBScript (1), VDF4, Vimscript, Visual Basic (1), Visual C++, Visual Foxpro, VSE, Webspeed, XSLT The answers covering 80386 assembler, VB6 and VBScript have been removed.

  • Convert a (nested)HTML unordered list of links to PHP array of links

    - by Klark
    Hi, I have a regular, nested HTML unordered list of links, and I'd like to scrape it with PHP and convert it to an array. The original list looks something like this: <ul> <li><a href="http://someurl.com">First item</a> <ul> <li><a href="http://someotherurl.com/">Child of First Item</a></li> <li><a href="http://someotherurl.com/">Second Child of First Item</a></li> </ul> </li> <li><a href="http://bogusurl.com">Second item</a></li> <li><a href="http://bogusurl.com">Third item</a></li> <li><a href="http://bogusurl.com">Fourth item</a></li> </ul> Any of the items can have children. (The actual screen scraping is not a problem, I can do that.) I'd like to turn this into a PHP array, of just the links, while keeping the hierarchical nature of the list. Any ideas? I've looked at using htmlsimpledom and phpQuery, which both use jQuery like syntax. But, I can't seem to get the syntax right. Thanks.

  • Using Tweet# to pull 5 most recent updates from a user

    - by Richard West
    I am working on a method that will allow me to pull in the 5 most recent posts that my company has made on it's Twitter account. One requirement of this web application is that it present these twitter posts as "regular" html in our website, so using the Twitter javascript method is ruled out. I have found Tweet#, a C# plugin that exposes the Twitter commands. This seems to be a nice way to pull this information but I have a question. I would like to be able to pull these updates from Twitter without authenticating to Twitter. Since the information is publically available I would think this would be fairly simple, however I'm having a problem with Tweet# wanting to do this. The cloest I have found to be able to do this requires my to login/authenticate with Twitter and then pull the 5 most recent tweets. Like this: var twitter = FluentTwitter.CreateRequest() .AuthenticateAs("UserName", "p@ssw0rd") .Configuration.CacheForInactivityOf(60.Seconds()) .Statuses().OnUserTimeline().Take(5).AsJson(); What I need is something that will allow my to specific the user id to pull the most recent 5 tweets from without authentication.

  • iPad app crashes when Youtube player clicked in UIWebView

  • Display HTML page in Office 2003 or 2007 task pane via VBA

    - by Malcolm
    Is it possible to display an HTML page in an Office 2003 and/or 2007 task pane via VBA? Background: We have a complicated configuration file that our users maintain in Word (using a real editor is not an option for our audience). We would like to create several toolbar buttons that display a basic HTML page in a task pane as a form of online help for our users. The reason we want to use a task pane to display help (vs. an external browser or traditional help engine) is so that the help content is "embedded" in Word vs. displayed via a seperate application. The problem with using a regular browser or help engine to display help is that users have to manually size and position both applications so that they can see them simultaneously and its very easy to "lose" one application when togging between many applications. We don't want to go down the route of writing a VisualStudio based task pane component - we want to keep things simple (KISS) and encapsulate everything in an easy to distribute Word template file (.dot or dotx.). Suggestions?

  • What is the correct way to synchronize a shared, static object in Java?

    - by johnrock
    This is a question concerning what is the proper way to synchronize a shared object in java. One caveat is that the object that I want to share must be accessed from static methods. My question is, If I synchronize on a static field, does that lock the class the field belongs to similar to the way a synchronized static method would? Or, will this only lock the field itself? In my specific example I am asking: Will calling PayloadService.getPayload() or PayloadService.setPayload() lock PayloadService.payload? Or will it lock the entire PayloadService class? public class PayloadService extends Service { private static PayloadDTO payload = new PayloadDTO(); public static void setPayload(PayloadDTO payload){ synchronized(PayloadService.payload){ PayloadService.payload = payload; } } public static PayloadDTO getPayload() { synchronized(PayloadService.payload){ return PayloadService.payload ; } } ... Is this a correct/acceptable approach ? In my example the PayloadService is a separate thread, updating the payload object at regular intervals - other threads need to call PayloadService.getPayload() at random intervals to get the latest data and I need to make sure that they don't lock the PayloadService from carrying out its timer task

  • How do I run JUnit from NetBeans?

    - by FarmBoy
    I've been trying to understand how to start writing and running JUnit tests. When I'm reading this article: http://junit.sourceforge.net/doc/testinfected/testing.htm I get the the middle of the page and they write, "JUnit comes with a graphical interface to run tests. Type the name of your test class in the field at the top of the window. Press the Run button." I don't know how to launch this program. I don't even know which package it is in, or how you run a library class from an IDE. Being stuck, I tried this NetBeans tutorial: http://www.netbeans.org/kb/docs/java/junit-intro.html It seemed to be going OK, but then I noticed that the menu options for this tutorial for testing a Java Class Library are different from those for a regular Java application, or for a Java Web App. So the instructions in this tutorial don't apply generally. I'm using NetBeans 6.7, and I've imported JUnit 4.5 into the libraries folder. What would be the normal way to run JUnit, after having written the tests? The JUnit FAQ describes the process from the Console, and I'm willing to do that if that is what is typical, but given all that I can do inside netbeans, it seems hard to believe that there isn't an easier way. Thanks much. EDIT: If I right-click on the project and select "Test" the output is: init: deps-jar: compile: compile-test: test-report: test: BUILD SUCCESSFUL (total time: 0 seconds) This doesn't strike me as the desired output of a test, especially since this doesn't change whether the test condition is true or not. Any ideas?

  • Using Entity Framework with an SQL Compact Private Installation

    - by David Veeneman
    I am using Entity Framework 4 in a desktop application with SQL Compact. I want to use a private installation of SQL Compact with my application, so that my installer can install SQL Compact without giving the user a second installation to do. It also avoids versioning hassles down the road. My development machine has SQL Compact 3.5 SP1 installed as a public installation, so my app runs fine there, as one would expect. But it's not running on my test machine, which does not have SQL Compact installed. I get this error: The specified store provider cannot be found in the configuration, or is not valid. I know some people have had difficulty with SQL Compact private installations, but I have used them for a while, and I really like them. Unfortunately, my regular private installation approach isn't working. I have checked the version numbers on my SQL CE files, and they are all 3.8.8078.0, which is the SP2 RC version. Here are the files I have included in my private installation: sqlcecompact35.dll sqlceer35EN.dll sqlceme35.dll sqlceqp35.dll sqlcese35.dll System.Data.SqlServerCe.dll System.Data.SqlServerCe.Entity.dll I have added a reference to System.Data.SqlServerCe to my project, and I have verified that all of the files listed above are being copied to the application folder on the installation machine. Here is the code I use to configure an EntityConnectionStringBuilder when I open a SQL Compact file: var sqlCompactConnectionString = string.Format("Data Source={0}", filePath); // Set Builder properties builder.Metadata = string.Format("res://*/{0}.csdl|res://*/{0}.ssdl|res://*/{0}.msl", edmName); builder.Provider = "System.Data.SqlServerCe.3.5"; builder.ProviderConnectionString = sqlCompactConnectionString; var edmConnectionString = builder.ToString(); Am I missing a file? Am I missing a configuration stepp needed to tell Entity Framework where to find my SQL Compact DLLs? Any other suggestions why EF isn't finding my SQL Compact DLLs on the installation machine? Thanks for your help.

  • Checking if a RoutedEvent has any handlers

    - by AK
    I've got a custom Button class, that always performs the same action when it gets clicked (opening a specific window). I'm adding a Click event that can be assigned in the button's XAML, like a regular button. When it gets clicked, I want to execute the Click event handler if one has been assigned, otherwise I want to execute the default action. The problem is that there's apparently no way to check if any handlers have been added to an event. I thought a null check on the event would do it: if (Click == null) { DefaultClickAction(); } else { RaiseEvent(new RoutedEventArgs(ClickEvent, this));; } ...but that doesn't compile. The compiler tells me that I can't do anything other than += or -= to an event outside of the defining class, event though I'm trying to do this check INSIDE the defining class. I've implemented the correct behavior myself, but it's ugly and verbose and I can't believe there isn't a built-in way to do this. I must be missing something. Here's the relevant code: public class MyButtonClass : Control { //... public static readonly RoutedEvent ClickEvent = EventManager.RegisterRoutedEvent("Click", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MyButtonClass)); public event RoutedEventHandler Click { add { ClickHandlerCount++; AddHandler(ClickEvent, value); } remove { ClickHandlerCount--; RemoveHandler(ClickEvent, value); } } private int ClickHandlerCount = 0; private Boolean ClickHandlerExists { get { return ClickHandlerCount > 0; } } //... }

  • 'Hot code replace' not working -- Eclipse doesn't change any code on JBoss

    - by Bernhard V
    Hello, fellow visitors! I'm currently experiencing a problem with 'hot code replace' not working on Eclipse Galileo and JBoss 4.2.3. Among other applications I'm running an exploded Java WAR on my local JBoss. The project from which it is build is managed by Maven. I build the project using the Maven goal war:exploded and then I copy that directory to JBoss with an ANT script. When I'm now running the application and set a breakpoint anywhere in the code, Eclipse properly halts at that line in the debug mode. But when I'm making a change to the source file and save it, Eclipse doesn't apply this change to the JBoss. For example, when I make a normal code line into a comment, the debugger still steps over this comment as if it was regular Java code. Or when I remove a line, the debugger seems to get out of sync with the file and starts stepping over parenthesis. But I'm not getting any 'hot code replace error'-messages either. It seems to me that Eclipse applies the changes to the source files, but doesn't apply it to the JBoss. Are there any special preferences that have to be turned on in order to make hot code replace work? Or are there any mistakes in how I build and deploy the application to the JBoss? I'd appreciate your help very much. Thank you. Bernhard V

  • Help with redirection for .com, .net and .org domains.

    - by user198553
    Hi all! I need help with some rules in ISAPI_Rewrite in my installation. I'm going to be very honest about my needs. I need to do this configuration in the next few hours, and don't have time right now understand everything about rewrites, regular expressions and such. I really think you can help me, if I had more reputation I would even set up a bounty... :( In fact, I believe that what I need is simple: I have a .com domain. The main url of my website is going to be http:// www.mainurl.com/. I have two other domains: mainurl.net and mainurl.org. What I need (in isapi-rewrite 2, the config made with httpd.ini file in root file) is: everytime someone writes mainurl.net in browser it becomes http:// www.mainurl.com/ 301 redirect. If it's written without www becomes http:// www.mainurl.com/. If someone writes mainurl.net/about it becomes http:// www.mainurl.com/about/. Redirect always the .com, the www part and the final slash /. Thanks in advance you all!
