• AnkhSVN: Cannot checkout Subsolution due to existing "versioned" folder

  - by lostiniceland

  Hello Everyone I am using Subversion since quite some time for Java-Development and I have setup a repository on my local NAS. Since I have a MSDN subscription via my company I recently installed Visual Studio 2010 to do a small project with .NET. According to some "best-practices" my project folder looks like the following. MySolution main.sln Services services.sln Service A files Service A Test files View projectfiles Persistence persistence.sln PersistenceXml files PersistenceXml Test files PersistenceDB files PersistenceDB Test files The idea is, that the main.sln only contains the projects for the application, meaning no test projects. The subsolutions, contain the project(s) and their corresponding testprojects. I was able to put all those projects under versioncontrol with AnkhSVN, so I have the same structure there in my trunk. Commiting changes was also no problem. Now I would like to check the this out on another machine. I was able to check out the main.sln which downloaded everything that was inside this solution. It skipped the services.sln, persistence.sln and all the test-projects. Until now everything is fine. Now, here comes the problem: when I am tryting to check out the subsolution (eg. services.sln) I get an error, I think it was UnsupportedOperation. I guess this happens because ankhsvn is tryting to download the folder Service A again and create ist hidden .svn folder which is already present. The only workaround I can think of by now is installing Tortoise SVN and check out the whole thing at once. It would be nicer though to have everything from within VS. Does anyone know how I can solve this? Is another client the only solution?

• Mamimum page fetch with maximum bandwith

  - by Ehsan

  Hi I want to create an application like a spider I've implement fetching page as the following code in multi-thread application but there is two problem 1) I want to use my maximum bandwidth to send/receive request, how should I config my request to do so (Like Download Accelerator application and the like) cause I heard the normal application will use 66% of the available bandwidth. 2) I don't know what exactly HttpWebRequest.KeepAlive do, but as its name implies I think i can create a connection to a website and without closing the connection sending another request to that web site using existing connection. does it boost performance or Im wrong public PageFetchResult Fetch() { PageFetchResult fetchResult = new PageFetchResult(); try { HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(URLAddress); HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); Uri requestedURI = new Uri(URLAddress); Uri responseURI = resp.ResponseUri; if (Uri.Equals(requestedURI, responseURI)) { string resultHTML = ""; byte[] reqHTML = ResponseAsBytes(resp); if (!string.IsNullOrEmpty(FetchingEncoding)) resultHTML = Encoding.GetEncoding(FetchingEncoding).GetString(reqHTML); else if (!string.IsNullOrEmpty(resp.CharacterSet)) resultHTML = Encoding.GetEncoding(resp.CharacterSet).GetString(reqHTML); req.Abort(); resp.Close(); fetchResult.IsOK = true; fetchResult.ResultHTML = resultHTML; } else { URLAddress = responseURI.AbsoluteUri; relayPageCount++; if (relayPageCount > 5) { fetchResult.IsOK = false; fetchResult.ErrorMessage = "Maximum page redirection occured."; relayPageCount = 0; return fetchResult; } req.Abort(); resp.Close(); return Fetch(); } } catch (Exception ex) { fetchResult.IsOK = false; fetchResult.ErrorMessage = ex.Message; } return fetchResult; }

• When downloading a file using FileStream, why does page error message refers to aspx page name, not

  - by StuperUser

  After building a filepath (path, below) in a string (I am aware of Path in System.IO, but am using someone else's code and do not have the opportunity to refactor it to use Path). I am using a FileStream to deliver the file to the user (see below): FileStream myStream = new FileStream(path, FileMode.Open, FileAccess.Read); long fileSize = myStream.Length; byte[] Buffer = new byte[(int)fileSize + 1]; myStream.Read(Buffer, 0, (int)myStream.Length); myStream.Close(); Response.ContentType = "application/csv"; Response.AddHeader("content-disposition", "attachment; filename=" + filename); Response.BinaryWrite(Buffer); Response.Flush(); Response.End(); I have seen from: http://stackoverflow.com/questions/736301/asp-net-how-to-stream-file-to-user reasons to avoid use of Response.End() and Response.Close(). I have also seen several articles about different ways to transmit files and have diagnosed and found a solution to the problem (https and http headers) with a colleague. However, the error message that was being displayed was not about access to the file at path, but the aspx file. Edit: Error message is: Internet Explorer cannot download MyPage.aspx from server.domain.tld Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. (page name and address anonymised) Why is this? Is it due to the contents of the file coming from the HTTP response .Flush() method rather than a file being accessed at its address?

• Build a Visual Studio Project without access to referenced dlls

  - by David Reis

  I have a project which has a set of binary dependencies (assembly dlls for which I do no have the source code). At runtime those dependencies are required pre-installed on the machine and at compile time they are required in the source tree, e,g in a lib folder. As I'm also making source code available for this program I would like to enable a simple download and build experience for it. Unfortunately I cannot redistribute the dlls, and that complicates things, since VS wont link the project without access to the referenced dlls. Is there anyway to enable this project to be built and linked in absence of the real referenced dlls? Maybe theres a way to tell VS to link against an auto generated stub of the dll, so that it can rebuild without the original? Maybe there's a third party tool that will do this? Any clues or best practices at all in this area? I realize the person must have access to the dlls to run the code, so it makes sense that he could add them to the build process, but I'm just trying to save them the pain of collecting all the dlls and placing them in the lib folder manually.

• Build and test on 2.2.1 iPod Touch with XCode 3.2.2?

  - by slewis

  I've just installed Xcode 3.2.2 with iPhone SDK 3.2 Beta 5 (Snow Leopard) This version of Xcode didn't come with any iPhone SDKs older than 3.0. But I want to create an app that runs on all devices from iPhone OS 2.2.1 - 3.1.3. I managed to add older SDKs into Xcode by downloading iPhone 3.1.3 with Xcode 3.1.4 and installing each 2.x SDK from the 'Packages' folder in the .dmg. So now I can select 2.2.1 as 'iPhone OS Deployment Target' and the 'Base SDK' as 3.1.3, and the app will build (thus letting me use 3.1.3 APIs with conditional coding whilst still running on 2.2.1 devices). But the problem is the app will not install and run on my 2.2.1 iPod Touch. Instead, Xcode tells me 'No provisioned iPhone OS device is connected'. If I bring up the Organizer, in the left column, the iPod Touch has an orange sphere next to it, instead of green, and clicking on this reveals: 'The version of iPhone OS on “iPod touch” is too old for use with this version of the iPhone SDK. Please restore the device to a version of the OS listed below' I'm not sure how to get this version of the SDK to support 2.2.1. (It needs to be this download of XCode/iPhone SDK because I also want it to be a universal binary so it runs on the iPad with a minimum of fuss).

• Syntactical analysis with Flex/Bison part 2

  - by Imran

  Hallo, I need help in Lex/Yacc Programming. I wrote a compiler for a syntactical analysis for inputs of many statements. Now i have a special problem. In case of an Input the compiler gives the right output, which statement is uses, constant operator or a jmp instructor to which label, now i have to write so, if now a if statement comes, first the first command (before the else) must be give out when the assignment of the if is yes then it must jump to the end because the command after the else isnt needed, so after this jmp then the second command must be give out. I show it in an example maybe you understand what i mean. Input adr. Output if(x==0) 10 if(x==0) Wait 5 20 WAIT 5 else 30 JMP 50 Wait 1 40 WAIT 1 end 50 END like so. I have an idea, maybe i can do it whith a special if statement like IF exp jmp_stmt_end stmt_seq END when the if statement is given in the input the compiler has to recognize the end ofthe statement and like my jmp_stmt in my compiler ( you have to download the files from http://bitbucket.org/matrix/changed-tiny) only to jump to the end. I hope you understand my problem.thanks.

• confused about how to use JSON in C#

  - by Josh

  The answer to just about every single question about using C# with json seems to be "use JSON.NET" but that's not the answer I'm looking for. the reason I say that is, from everything I've been able to read in the documentation, JSON.NET is basically just a better performing version of the DataContractSerializer built into the .net framework... Which means if I want to deserialize a JSON string, I have to define the full, strongly-typed class for EVERY request I might have. so if I have a need to get categories, posts, authors, tags, etc, I have to define a new class for every one of these things. This is fine if I built the client and know exactly what the fields are, but I'm using someone else's api, so I have no idea what the contract is unless I download a sample response string and create the class manually from the JSON string. Is that the only way it's done? Is there not a way to have it create a kind of hashtable that can be read with json["propertyname"]? Finally, if I do have to build the classes myself, what happens when the API changes and they don't tell me (as twitter seems to be notorious for doing)? I'm guessing my entire project will break until I go in and update the object properties... So what exactly is the general workflow when working with JSON? And by general I mean library-agnostic. I want to know how it's done in general, not specifically to a target library... I hope that made sense, this has been a very confusing area to get into... thanks!

• Carriage Return\Line feed in Java

  - by Manu

  Guys, i have created text file in unix enviroment using java code. For writing the text file i am using java.io.FileWriter and BufferedWriter. and for newline after each row i am using bw.newLine() method. (where bw is object of BufferedWriter ) and sending that text file by attaching in mail from unix environment itself (automated that using unix commands). My issue is, after i download the text file from mail in windows system, if i opened that text file the data's are not properly aligned. newline() character is not working i think so. I want same text file alignment as it is in unix environment, if i opened the text file in windows environment also. How to resolve the problem.Please help ASAP. Thanks for your help in advance. pasting my java code here for your reference..(running java code in unix environment) File f = new File(strFileGenLoc); BufferedWriter bw = new BufferedWriter(new FileWriter(f, false)); rs = stmt.executeQuery("select * from jpdata"); while ( rs.next() ) { bw.write(rs.getString(1)==null? "":rs.getString(1)); bw.newLine(); }

• Maven dependency for Servlet 3.0 API?

  - by deamon

  How can I tell Maven 2 to load the Servlet 3.0 API? I tried: <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>3.0</version> <scope>provided</scope> </dependency> I use http://repository.jboss.com/maven2/ but what repository would be correct? Addendum: It works with a dependency for the entire Java EE 6 API and the following settings: <repository> <id>java.net</id> <url>http://download.java.net/maven/2</url> </repository> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> I'd prefer to only add the Servlet API as dependency, but "Brabster" may be right that separate dependencies have been replaced by Java EE 6 Profiles. Is there a source that confirms this assumption?

• NSTimer as a timeout mechanism

  - by alexantd

  I'm pretty sure this is really simple, and I'm just missing something obvious. I have an app that needs to download data from a web service for display in a UITableView, and I want to display a UIAlertView if the operation takes more than X seconds to complete. So this is what I've got (simplified for brevity): MyViewController.h @interface MyViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> { NSTimer *timer; } @property (nonatomic, retain) NSTimer *timer; MyViewController.m @implementation MyViewController @synthesize timer; - (void)viewDidLoad { timer = [NSTimer scheduledTimerWithTimeInterval:20 target:self selector:@selector(initializationTimedOut:) userInfo:nil repeats:NO]; [self doSomethingThatTakesALongTime]; [timer invalidate]; } - (void)doSomethingThatTakesALongTime { sleep(30); // for testing only // web service calls etc. go here } - (void)initializationTimedOut:(NSTimer *)theTimer { // show the alert view } My problem is that I'm expecting the [self doSomethingThatTakesALongTime] call to block while the timer keeps counting, and I'm thinking that if it finishes before the timer is done counting down, it will return control of the thread to viewDidLoad where [timer invalidate] will proceed to cancel the timer. Obviously my understanding of how timers/threads work is flawed here because the way the code is written, the timer never goes off. However, if I remove the [timer invalidate], it does.

• program won't find math.h anymore

  After a long time, I downloaded a program I co-developed and tried to recompile it on my Ubuntu Linux 12.04, but it seems it does not find math.h anymore.

• Why can't I simply copy installed Perl modules to other machines?

  - by pistacchio

  Being very new to Perl but not to dynamic languages, I'm a bit surprised at how not straight forward the manage of modules is. Sure, cpan X does theoretically work, but I'm working on the same project from three different machines and OSs (at work, at home, testing in an external environment). At work (Windows 7) I have problem using cpan because of our firewall that makes ftp unusable At home (Mac OS X) it does work In the external environment (Linux CentOs) it worked after hours because I don't have root access and I had to configure cpan to operate as a non-root user I've tried on another server where I have an access. If the previous external environment is a VPS and so I have a shell access, this other one is a cheap shared hosting where I have no way to install new modules other than the ones pre-installed At the moment I still can't install Template under Windows. I've seen that as an alternative I could compile it and I've also tried ActiveState's PPM but the module is not existent there. Now, my perplexity is about Perl being a dynamic language. I've had all these kind of problems while working, for example, with C where I had to compile all the libraries for all the platform, but I thought that with Perl the approach would have been very similar to Python's or PHP's where in 90% of the cases copying the module in a directory and importing it simply works. So, my question: if Perl's modules are written in Perl, why the copy/paste approach will not work? If some (or some part) of the modules have to be compiled, how to see in CPAN if a module is Perl-only or it relies upon compiled libraries? Isn't there a way to download the module (tar, zip...) and use cpan to deploy it? This would solve my problem under Windows.

• Using maven to distribute a swing application that can have each dependency individually tracked

  - by tms

  I'm moving my project to Maven and eventually OSGi. I currently distribute the project is a large Zip file with all the dependencies. Although my projects code is only 20% of the total package I have to redistribute all the dependency. With smaller independent modules this may be even less. Looking here on stack overflow it seems that to keep my current plan the maven-assembly-plugin should do the trick. I was considering having a base installer that would look at a XML manifest, then collect all the libraries that needed to be updated. This would mean that libraries that change occasionally would be downloaded less often. This also makes since for something like OSGi plugins (which could have independent release schedules). In essence I want my software to look and manage individual libraries, and download on demand (based on the manifest). I was wondering if there is a "maven way" of generating this Manifest and publishing all the libraries to a website? I believe the deploy life-cycle would do the second step. As an alternative, is there a OpenSource Java library that does this type of deployment? I don't want to embed Maven or something larger with the distributed code. The application is not for coders, the simpler the better, and the smaller the installer the better.

• Installer downloads wrong version of sql server compact edition

  - by MartinStettner

  I have a Visual Studio setup project which defines SQL Server 3.5 as prerequisite. I also set it up to download the required files from the source (i.e. Microsoft). My project uses Sql Server 3.5 SP1. If I create the installer on my development machine, everything works fine. When the installer is built on the build machine, it downloads the "old" 3.5 version (without SP1) which makes my application crash. (If I install SP1 on the test system manually, the application just works find...) I installed both Visual Studio 2008 SP1 and Sql Server 3.5 SP1 on the build machine. This seems to be some issue with the prerequisite packages but they look the same on the development and the build machines. Any idea what goes wrong here? EDIT Ok, I rechecked it and the package descriptions are'nt the sames. Oddly enough, the .msi file is the right one on the build machine but the old one on the development machine, so I guess if I tried to build an installer which includes the prerequisites, I'd get the wrong result on the dev machine and the right one on the build machine. Extended question: How are the prerequesite packages (under C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\SQL Server Compact Edition) meant to be updated to SP1? Is the SQL Server CE SP1 installer responsible for this?

• Deploy an hta file in an exe or msi file

  - by rjmunro

  I've written an HTA file frontend for our web app that allows the web app to run without web browser status bars etc, and allows it to access the local system for certain tasks. I need a way to deploy this to customers. I need an installer to supply an hta file, an ico file, and add a link to them in the start menu and on the users desktop. I looked at building an installer with NSIS, but I couldn't figure out how to assign the icon to the shortcuts - The icon had to be a standard HTA one. Can this be done with NSIS, or should I be using another installer? P.s. I've got no particular preference for NSIS, it's just something I once used a very long time ago. When I download stuff, I think I prefer them to be msi files that launch with windows installer (it feels more like downloading a .rpm or .deb on linux which I am used to) but I know nothing about how those are created. I'm a web/linux guy who knows very little about windows programming.

• How to install Zend Framework on Windows

  - by sombe

  "installing Zend Framework is so easy!!!!" yeah right... Ok I'm working with a beginner's book and the ONE thing that is not excessively detailed is the most important part: Installing the darn thing. After browsing the quickstart guide for hours, all it said was: "download Zend [...] add the include directory (bla bla) and YOU'RE DONE!" right, i'm done using Zend. Ok, not really, not yet anyway. I beg of you people, I wanna go to bed, please tell me how (in simple 6th grade detail) to install the framework. I've got the unzipped folder in my htdocs directory, and I placed zf.bat+zf.php in the htdocs root. What's next? thank you so much. EDIT: Thanks guys for all the answers. Unfortunately I haven't been able to work with this or find a good enough resource to explain it to me in plain english. It seems that this framework adheres more so to programmers than to beginners. I've since yesterday read a little on CakePHP and found that it was incredibly easy to install and tune. As oppose to Zend Framework, where I had to dig in my "environment variables", configure "httpd.conf" and almost tie the knot between my computer driver cables to just get it running, CakePHP has already allowed me to put together a nice newbie application. In conclusion, I very much appreciate all of your help. I hope someone else venturing on ZF will be more successful with it. Thanks!

• Editing a remote file on-the-fly with PHP

  - by user275074

  Hi, I have a requirement to edit a remote text file on-the-fly, the content of which currently stands at ~1Mb. I have tried a couple of approaches and both seem to be clunky or hog memory which I can't rely on. Thinking out logically what I'm trying to achieve is: FTP to a remote server. Download a copy of the file for backup purposes and store it somewhere locally. Open the remote file and add the necessary lines required. Remove lines from the remote file as per an array of un-required data generated from the local server. Is this possible? I've managed to code steps 1 and 2 but I'm having difficult with 3 and 4. The way I'm doing it now is to use fgets and return the whole string. Really, I don't want to do this as it involves manipulating and re-generating the whole string (and it's large) and then re-inserting it in between two markers in the remote file. Is there no way of manipulating the lines of text in the file on-the-fly?

When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity. I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack. The only way I can find that this is possible is if both AsyncTasks' onPostExecute() executed SO simultaneously that they were virtually running the same lines at the same time, since I set the 'itemXdownloaded' flag to true right before I check for both and call startActivity(). But this is happening enough that it's very hard for me to believe that both downloads are finishing precisely at the same time and having their onPostExecute()s so close together... Any thoughts on what could be going on here? General gist of code (details removed, ignore any syntactical errors I may have edited in): // In onPostExecute() switch (downloadID) { case DL1: dl1complete = true; break; case DL2: dl2complete = true; break; case DL3: dl3complete = true; break; } // If 1 and 2 are done, move on (DL3 still going in background) if ( downloadID != DL3 && dl1complete && dl2complete) { ParentClass.this.startActivity(new Intent(ParentClass.this, NextActivity.class)); }

• Error creating Google Calendar

  - by Don

  Hi, I'm trying to use the Google Calendar Java API to create a secondary calendar for a Google apps user. The relevant code is: // Initialise the API client CalendarService googleCalendar = new GCalendarService("canimo.ca"); googleCalendar.setUserCredentials("[email protected]", "secret"); // Create the calendar CalendarEntry cal = new CalendarEntry(); cal.title = new PlainTextConstruct(user.email); cal.summary = new PlainTextConstruct("Collection calendar"); cal.timeZone = new TimeZoneProperty("America/Montreal"); cal.hidden = HiddenProperty.FALSE; googleCalendar.insert(CALENDAR_URL, calendar); The call to insert() above results in com.google.gdata.util.ServiceException: Internal Server Error and no calendar is created. If I try and perform the same operation through the Google calendar website, it also fails with the error message: We could not save changes. Please try again in a few minutes. An obvious conclusion is that there's some problem on Google's side, but this has been going on for several days now. Strangely, if I create a new user, everything works fine for a while. I can create calendars via the website, and download them via the API. But as soon as I try and create a new calendar using the API, I get the exception above, and thereafter can't create new calendars using either the website or the API. Thanks, Don

• Developer friendly open-source license?

  - by Francisco Garcia

  As a software engineer/programmer myself, I love the possibility to download the code and learn from it. However building software is what brings food to my table. I have doubts regarding the type of license I should use for my own personal projects or when picking up one project to learn from. There are already many questions about licenses on Stackoverflow, but I would like to make this one much more specific. If your main profession and way of living is building software, which type of license do you find more useful for you? And I mean, the license that can benefit you most as a professional because it gives you more freedom to reuse the experience you gain. GPL is a great license to build communities because it forces you to give back your work. However I like BSD licenses because of their extra freedom. I know that if the code I am exploring is BSD licensed, I might be able to expand not only my skills, but also my programmer toolbox. Whenever I am working for a company, I might recall that something similar was done in another project and I will be able to copy or imitate certain part of the code. I know that there are religious wars regarding GPL vs BSD and it is not my intention to start one. Probably many companies already take snipsets from GPL projects anyway. I just want to insist in the factor of professional enrichment. I do not intend to discriminate any license. I said I prefer BSD licenses but I also use Linux because the user base is bigger and also the market demand.

• Why does my javascript file sometimes compressed while sometimes not?(IIS Gzip problem)

  - by Kevin Yang

  i enable gzip for javascript file in my iis settings, here 's the corresponding config section. <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" staticCompressionLevel="10" dynamicCompressionLevel="8" /> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/soap+msbin1" enabled="true" /> <add mimeType="*/*" enabled="false" /> </dynamicTypes> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/javascript" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </staticTypes> </httpCompression> currently, when i download my js file, it seems that sometimes server return the gzip one, and sometimes not. i dont know why, and how to debug that. If a file is already gzipped, it should be cached in local disk, and next time someone visit that file again, iis kernel should return the cache gzip file directly without compressing it again. Is that right?
