  • Cannot display converted value inside xml field

    - by zurna
    PS: My bad, there was not an error. I forgot to upload the latest version to the server... I have multimedias and images table. I save images in multimedias table with their images table id numbers. Then whenever I need image's url, with a simple function I get it from images table. The problem I am having is when I try to display image's url inside ImageURL, it just does not happen. This is very annoying. xml output <?xml version='1.0' encoding='windows-1254' ?> <rows><row id='1'> <MultimediaTitle>Hagi Goals</MultimediaTitle> /FLPM/media/images/5Y2K4T5V_sm.jpg <ImageURL><![CDATA[]]></ImageURL> <Videos> <VideoID id='1'><VideoURL>/FLPM/media/videos/0H7T9C0F.flv</VideoURL></VideoID> <VideoID id='2'><VideoURL>/FLPM/media/videos/9L6X9G9J.flv</VideoURL></VideoID> </Videos> </row> </rows>

  • Logging in "Java Library Code" libs for Android applications

    - by K. Claszen
    I follow the advice to implement Android device (not application!) independent library code for my Android Apps in a seperate "Java Library Code" project. This makes testing easier for me as I can use the standard maven project layout, Spring test support and Continuous Build systems the way I am used to. I do not want to mix this inside my Android App project although this might be possible. I now wonder how to implement logging in this library. As this library will be used on the Android device I would like to go with android.util.Log. I added the followind dependency to my project to get the missing Android packages/classes and dependencies: <dependency> <groupId>com.google.android</groupId> <artifactId>android</artifactId> <version>2.2.1</version> <scope>provided</scope> </dependency> But this library just contains stub method (similar to the android.jar inside the android-sdk), thus using android.util.Log results in java.lang.RuntimeException: Stub! when running my unit tests. How do I implement logging which works on the Android device but does not fail outside (I do not expect it to work, but it must not fail)? Thanks for any advice Klaus For now I am going with the workaround to catch the exception outside android but hope there is a better solution. try { Log.d("me", "hello"); } catch (RuntimeException re) { // ignore failure outside android }

  • How to save XML file before update?

    - by Robert Iagar
    Right so I have a simple app that consists of a calendar a Set Event button and list box that populates using a DataTemplate in WPF. When I build the app the Events.xml file is like this: <?xml version="1.0" encoding="utf-8" ?> <events> </events> I add events to xml through code. Final structure of the xml file is the following <?xml version="1.0" encoding="utf-8" ?> <events> <event Name="Some Name"> <startDate>20.03.2010</startDate> <endDate>29.03.2010</endDate> </event> </event> Now here's my problem. If I update the app and deploy it with Click Once and the app updates it self, I lose the list because the new file is empty. Any workaround this? Here's how I add the Data: var xDocument = XDocument.Load(@"Data\Events.xml"); xDocument.Root.Add(new XElement("event", new XAttribute("name", event.Name), new XElement("startDate", startDate), new XElement("endDate", endDate) ) ); xDocument.Save(@"Data\Events.xml");

  • Tracking down slow managed DLL loading

    - by Alex K
    I am faced with the following issue and at this point I feel like I'm severely lacking some sort of tool, I just don't know what that tool is, or what exactly it should be doing. Here is the setup: I have a 3rd party DLL that has to be registered in GAC. This all works fine and good on pretty much every machine our software was deployed on before. But now we got 2 machines, seemingly identical to the ones we know work (they are cloned from the same image and stuffed with the same hardware, so pretty much the only difference is software settings, over which I went over and over, and they seem fine). Now the problem, the DLL in GAC takes a very long time to load. At least I believe this is the issue, what I can say definitively is that instantiating a single class from that DLL is the slow part. Once it is loaded, thing fly as they always have. But while on known-good machines the DLL loads so fast that a timestamp in the log doesn't even change, on these 2 machines it take over 1min to load. Knowns: I have no access to the source, so I can't debug through the DLL. Our app is the only one that uses it (so shouldn't be simultaneous access issues). There is only one version of this DLL in existance, so it shouldn't be a matter of version conflict. The GAC reference is being used (if I uninstall the DLL from GAC, an exception will be thrown about the missing GAC reference). Could someone with a greater skill in debug-fu suggest what I can do to track down the root cause of this issue?

  • Visual Studio 2012 won't start

    - by David Aleu
    I installed VS2012 Premium from our MSDN subscription and it was working fine the first couple of days but then I installed a few extensions I can't now start VS2012 and it gives the error: Faulting application name: devenv.exe, version: 11.0.50727.1, time stamp: 0x5011ecaa Faulting module name: ntdll.dll, version: 6.1.7601.17725, time stamp: 0x4ec49b8f Exception code: 0xc0000374 Fault offset: 0x000ce6c3 Faulting process id: 0xee8 Faulting application start time: 0x01cd89bb777fc1dd Faulting application path: C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe Faulting module path: C:\Windows\SysWOW64\ntdll.dll I'm running it on Windows 7 64 bit. I've tried to repair, uninstall and install again and nothing. I tried to restore to a previous restore system point but nothing. The extensions I installed I can remember: VS10x Code Map VSCommands Visual SVN Nuget manager (all the above my colleagues have it too and it works fine for them) and: Web Essentials Visual Studio Color Theme Editor SlowCheetah Mobile Ready HTML5 Questions are: Anyone else has had this problem? Is there a way I can uninstall extensions from a command line or software? (I removed the extensions folder but that doesn't do anything) Can I repair the "C:\Windows\SysWOW64\ntdll.dll"? Is it really a problem with this dll? I haven't been able to find any similar issue in other versions and because VS2012 is new doesn't seem to be much information either.

  • Scala path dependent return type from parameter

  • Subversion freaking out on me!

    - by Malfist
    I have two copies of a site, one is the production copy, and the other is the development copy. I recently added everything in the production to a subversion repository hosted on our linux backup server. I created a tag of the current version and I was done. I then copied the development copy overtop of the production copy (on my local machine where I have everything checked out). There are only 10-20 files changed, however, when I use tortoise SVN to do a commit, it says every file has changed. The diff file generated shows subversion removing everything, and replacing it with the new version (which is the exact same). What is going on? How do I fix it? An example diff: Index: C:/Users/jhollon/Documents/Visual Studio 2008/Projects/saloon/trunk/components/index.html =================================================================== --- C:/Users/jhollon/Documents/Visual Studio 2008/Projects/saloon/trunk/components/index.html (revision 5) +++ C:/Users/jhollon/Documents/Visual Studio 2008/Projects/saloon/trunk/components/index.html (working copy) @@ -1,4 +1,4 @@ -<html> -<body bgcolor="#FFFFFF"> -</body> +<html> +<body bgcolor="#FFFFFF"> +</body> </html> \ No newline at end of file

  • Should TcpClient be used for this scenario?

    - by Martín Marconcini
    I have to communicate with an iPhone. I have its IP Address and the port (obtained via Bonjour). I need to send a header that is “0x50544833” (or similar, It’s an HEX number), then the size of the data (below) and then the data itself. The data is just a string that looks like this: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE plist SYSTEM "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>clientName</key> <string>XXX</string> <key>clientService</key> <string>0be397e7-21f4-4d3c-89d0-cdf179a7e14d</string> <key>registerCode</key> <string>0000</string> </dict> </plist> The requirement also says that I must send the data in little endian format (which I think is the default for Intel anyway). So it would be: hex_number + size of data + string_with_the_above_xml. I need to send that to the iPhone and read the response. What would be, according to your experience, the best way to send this data (and read the response)?

  • Kohana Auth Library Deployment

    - by Steve
    My Kohana app runs perfectly on my local machine. When I deployed my app to a server (and adjust the config files appropriately), I can no longer log into the app. I've traced through the app login routine on both my local version and the server version and they both agree with each other all the way through until you get to the auth.php controller logged_in() routine where suddenly, at line 140 - the is_object($this-user) test - the $user object no longer exists!?!?!? The login() function call that calls the logged_in() function successfully passes the following test, which causes a redirect to the logged_in() function. if(Auth::instance()->login($user, $post['password'])) Yes, the password and hash, etc all work perfectly. Here is the offending code: public function logged_in() { if ( ! is_object($this->user)) { // No user is currently logged in url::redirect('auth/login'); } etc... } As the code is the same between my local installation and the server, I reckon it must be some server setting that is messing with me. FYI: All the rest of the code works because I have a temporary backdoor available that allows me to use the application (view pages of tables, etc) without being logged in. Any ideas?

  • Handle BACK key event in child view

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

  • How to provide i18n service for developer and end user

    - by user247245
    Many android applications have quite poor i18n-support, and for an understandable reason, as it adds much work for the developer. From a both intuitive and cultural point of view it would be a good thing if end-users could translate the apps themself, and OTA share the translation, without reinstalling the app itself. In concept; as wikipedia, some add content easily, others only use what's there. It's of course important that the service is as easy as possible to use, both for app-developers, and people willing to transcribe. To keep it simple, this is the solution I'm concidering; Developer perspective: Developer uses a customized setContentView when open activities/layouts that will seach for thanslations of xml-entries. (below) The customized version is provided as a free downloadable library/class..., turning the i18n feature to more or less a one liner. User perspective: User downloads app without any translation As app launches, it checks locale running at phone, and will look for a translated xml-file at shared space in SD. If no or old transcribed xml (above), try to download new from internet-service (ansync). This is all done by library above, no need for intents. Translator perspective: Separate app to provide translations for any app using the i18n service above. (Could be just a webapp), with some form of QA on translators/input. QUESTION: Now, for this to work efficiently, it has to be AeasyAP for the developer to even bother, and the most fluent solution would be a customized version of setContentView, that simply loads the translated values from external xml, instead of the ones in the apk. Is this possible at all, and if not, what's your suggested solutions? (And of course, Happy New Year, feliz ano novo, blwyddyn newydd dda, Gott Nytt År, kontan ane nouvo, szczesliwego nowego roku ...) Regards, /T

  • Glassfish 3: How do I get and use a developers build so I can navigate a stack trace including Glas

    - by Thorbjørn Ravn Andersen
    I am migrating a JSF 1.1 application to JEE 6 Web profile, and doing it in steps. I am in the process of moving from JSP with JSF 1.1 to Facelets under JSF 1.2 using the jsf-facelets.jar for JSF 1.2, and received an "interesting" stack trace when trying to lookup a key in a Map using a "{Bean.foo.map.key}" where the stacktrace complained about "key" not being a valid integer. (After code introspection I am workarounding it using a number as the key). That bug is not what this question is about. In such a situation it is essential to be able to navigate the source of every line in the stack trace. In Eclipse I normally attach a source jar to every jar on the build path, but in this particular case the Glassfish server adapter creates a library automatically containing the jars. Also there is to my knowledge no debug build of Glassfish where sources are included in the bundle. Glassfish is a non-trivial Maven project, and a bit picky too. I am not very familiar with maven, but have managed to checkout the code from Subversion and build it for the 3.0 tag according to http://wiki.glassfish.java.net/Wiki.jsp?page=V3FullBuildInstructions#section-V3FullBuildInstructions-CheckoutTheWorkspace - it appears to be the code corresponding to the official released 3.0 version. After finishing the "mvn -U install" part, I have then tried to create Eclipse projects by first using "mvn -DdownloadSources=true eclipse:eclipse" and then import them in Eclipse JEE 3.5.2 and specifying the M2_REPO variable but many of the projects still have compilation errors, and I cannot locate any instructions from Oracle about how to do this. I'd appreciate some help in just getting a functional IDE workspace reflecting the 3.0 version of Glassfish. I have Eclipse 3.5.2, Netbeans 6.8 and 6.9 beta, and IntelliJ IDEA 9, and Linux/Windows/OS X do do it on.

  • Why won't EF4 generate a method to support my Function Import?

    - by Deane
    I have a stored proc in my database which returns an integer. I added a Function Import to my model. This appears in the EDMX file: <Function Name="GetTotalEntityCount" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="false" ParameterTypeSemantics="AllowImplicitConversion" Schema="dbo" /> However, no method actually gets generated for this. It should be top level, right? using (MyContext context = new MyContext()) { context.MyMethodShouldBeRightHere(); } Nothing appears in Intellisense, I've gone through the designer.cs file and there's nothing in there, and reflected the DLL...nothing. The code generator is just not generating any code to support this stored proc. I added another table to my database and updated the model, and that came in, so the model will update, it's just specifically ignoring this stored proc. I've tried everything I can think of, and consulted every resource I can find, and as near as I can tell, I'm doing everything right. I'm using EF4, database-first. (I'm pretty sure on the version, anyway. This shows up in the generated file: Runtime Version:4.0.30319.1 )

  • xsl:template match doesn't find matches

    - by dmo
    I'm trying to convert some Xaml to HTML using the .NET XslCompiledTransform and am running into difficulties getting the xslt to match Xaml tags. For instance with this Xaml input: <FlowDocument PagePadding="5,0,5,0" AllowDrop="True" NumberSubstitution.CultureSource="User" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> <Paragraph>a</Paragraph> </FlowDocument> And this xslt: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="html" indent="yes"/> <xsl:template match="/"> <html> <body> <xsl:apply-templates /> </body> </html> </xsl:template> <xsl:template match="FlowDocument"> <xsl:apply-templates /> </xsl:template> <xsl:template match="Paragraph" > <p> <xsl:apply-templates /> </p> </xsl:template> I get this output: <html> <body> a </body> </html> Rather than the expected: <html> <body> <p>a</p> </body> </html> Could this be a problem with the namespace? This is my first attempt at an xsl transform, so I'm at a loss.

  • Is this XML file correct for RSS feeding?

    - by Hermet
    Hi guys I am generating a XML-RSS type file from PHP. The output for example is like this <?xml version="1.0" encoding="iso-8859-1"?> <rss version="2.0"> <channel> <title>Mi web mola</title> <link>http://www.dominio.com/blog.php</link> <language>es-ES</language> <description>Mallas y eso</description> <generator>Autor</generator> <item> <title>Articulo de prueba</title> <link>http://www.midominio.com/2342</link> <pubDate>14/06/2010</pubDate> <description><![CDATA[Descripcion de prueba bla bla bla]]></description> <content:encoded><![CDATA[Contenido prueba]]></content:encoded> </item> </channel> </rss> ... and all I can see in the Firefox preview is the title and the description of the blog, not the items, but in the source it appears correctly, so I've thought it must be a parse error or something like that.. What could be wrong? Again, excuse me for my bad english, and thank you very much.

  • Is it possible to De-Serialize a new Derived class using Old Binary?

    - by Anand
    In my project I have a class which I Serialize in Binary format to the disk. Due to some new requirement I need to create a new class which is derived from the original class. eg [Serializable] public class Sample { String someString; int someInt; public Sample() { } public Sample(String _someString, int _someInt) { this.someInt = _someInt; this.someString = _someString; } public String SomeString { get { return someString; } } public int SomeInt { get { return someInt; } } } [Serializable] public class DerivedSample : Sample { String someMoreString; int someMoreInt; public DerivedSample () : base() { } public DerivedSample (String _someString, int _someInt, String _someMoreString, int _someMoreInt) : base(_someString, _someInt) { this.someMoreString = _someMoreString; this.someMoreInt = _someMoreInt; } public String SomeMoreString { get { return someMoreString; } } public int SomeMoreInt { get { return someMoreInt; } } } When I try to De serialize an old file which contains only object of Sample it works fine, in the current assembly. That means backward compatibility is there. But when I try to deserialize the file which contains object of DerivedSample using the previous version of the assembly application crashes. Which means forward compatibilty needs to be taken care off... It it possible to say read only the base class part of the object from new version of the file?

  • C: Fifo between threads, writing and reading strings

    - by Yonatan
    Hello once more dear internet, I writing a small program that among other things, writes a log file of commands received. to do that, I want to use a thread that all it should do is just attempt to read from a pipe, while the main thread will write into that pipe whenever it should. Since i don't know the length of each string command, i thought about writing and reading the pointer to the char buf[MAX_MESSAGE_LEN]. Since what i've tried so far doesn't work, i'll post my best effort :P char str[] = "hello log thread 123456789 10 11 12 13 14 15 16 17 18 19\n"; if (pipe(pipe_fd) != 0) return -1; pthread_t log_thread; pthread_create(&log_thread,NULL, log_thread_start, argv[2]); success_write = 0; do { write(pipe_fd[1],(void*)&str,sizeof(char*)); } while (success_write < sizeof(char*)); and the thread does this: char buffer[MAX_MSGLEN]; int success_read; success_read = 0; //while(1) { do { success_read += read(pipe_fd[0],(void*)&buffer, sizeof(char*)); } while (success_read < sizeof(char*)); //} printf("%s",buffer); (Sorry if this doesn't indent, i can't seem to figure out this editor...) oh, and pipe_fd[2] is a global parameter. So, any help with this, either by the way i thought of, or another way i could read strings without knowing the length, would be much appreciated. On a side note, i'm working on Eclipse IDE C/C++, version 1.2.1 and i can't seem to set up the compiler so it will link the pthread library to my project. I've resorted to writing my own Makefile to make it (pun intended :P) work. Anyone knows what to do ? i've looked online, but all i find are solutions that are probably good on an older version because the tabs and option keys are different. Anyways, Thanks a bunch internet ! Yonatan

  • Converting string to a simple type

    - by zespri
    .Net framework contains a great class named Convert that allows conversion between simple types, DateTime type and String type. Also the class support conversion of the types implementing IConvertible interface. The class has been implemented in the very first version of .Net framework. There were a few things in the first .Net framework that were not done quite right. For example .Parse methods on simple types would throw an exception if the string couldn't be parsed and there would be no way to check if exception is going to be thrown in advance. A future version of .Net Framework removed this deficiency by introducing the TryParse method that resolved this problem. The Convert class dates back to time of the old Parse method, so the ChangeType method on this class in implemented old style - if conversion can't be performed an exception is thrown. Take a look at the following code: public static T ConvertString<T>(string s, T @default) { try { return (T)Convert.ChangeType(s, typeof(T), CultureInfo.InvariantCulture); } catch (Exception) { return @default; } } This code basically does what I want. However I would pretty much like to avoid the ugly try/catch here. I'm sure, that similar to TryParse, there is a modern method of rewriting this code without the catch-all. Could you suggest one?

  • RMagick transparent_color deprecated? What's the alternative?

    - by user315975
    I'm developing an app that does a fair amount of generating transparent pngs on the fly. These are used as overlays, to show areas of interest in a graphic, so they have to have transparent backgrounds. I am developing in Ruby on Rails, deploying on Heroku. What works fine in development is not working in production. I get this error when I call a drawing routine using RMagick: NotImplementedError (the `transparent_color=' method is not supported by ImageMagick 6.2.4): /usr/local/lib/ruby/gems/1.8/gems/rmagick-1.15.17/lib/RMagick.rb:1691:in `transparent_color=' I'm using RMagick version 2.12.1 on the development machine, but I'm not exactly certain how to discover the version of ImageMagick that it's running, so I'm not sure if this is a case of my local code being behind or ahead. I'm hoping behind, because perhaps then there'll be a replacement for this call. Does anyone know what the fix is here? What's required to generate a transparent background, if not the call I'm using? I can't find this in the documentation: in fact, it was on a third-party site that I found mention of this capability.

  • Multi-client C# ODBC (Sybase/Oracle/MSSQL) table access question.

    - by Hamish Grubijan
    I am working on a feature that would allow clients pick a unique identifier (ci_name). The code below is a generic version that gets expanded to the right sql depending on the vendor. Hopefully it makes sense. #include "sql.h" create table client_identification ( ci_id TYPE_ID IDENTITY, ci_name varchar(64) not null, constraint ci_pk primary key (ci_name) ); go CREATE_SEQUENCE(ci_id) There will be simple stored procedures for adding, retrieving, and deleting these user records. This will be used by several admins. This will not happen very frequently, but there is still a possibility that something will be added or deleted since the list was initially retrieved. I have not yet decided if I need to detect the case of a double delete, but the user name cannot be created twice - primary key constraint will object. I want to be able to detect this particular case and display something like: "you snooze - you loose." :) I would like to leverage the pk constraint instead of doing some extra sql gymnastics. So, how can I detect this case cleanly, so that it works in MS SQL 2008, Sybase, and Oracle? I hope to do better than catch a general ODBC exception and parse out the text and look for what Sybase, Oracle, and MSSQL would give me back. Oracle is a little different. We actually prepend these variables to the Oracle version of stored procedures because they are not available otherwise: Vret_val out number, Vtran_count in out number, Vmessage_count in out number, Thanks. General helpful tips and comments are welcome, except for naming convention ones ( I do not have a choice here, plus I mangled the actual names a bit).

  • How to use linux csplit to chop up massive XML file?

    - by Fred
    Hi everyone, I have a gigantic (4GB) XML file that I am currently breaking into chunks with linux "split" function (every 25,000 lines - not by bytes). This usually works great (I end up with about 50 files), except some of the data descriptions have line breaks, and so frequently the chunk files do not have the proper closing tags - and my parser chokes halfway through processing. Example file: (note: normally each "listing" xml node is supposed to be on its own line) <?xml version="1.0" encoding="UTF-8"?> <listings> <listing><date>2009-09-22</date><desc>This is a description WITHOUT line breaks and works fine with split</desc><more_tags>stuff</more_tags></listing> <listing><date>2009-09-22</date><desc>This is a really annoying description field WITH line breaks that screw the split function</desc><more_tags>stuff</more_tags></listing> </listings> Then sometimes my split ends up like <?xml version="1.0" encoding="UTF-8"?> <listings> <listing><date>2009-09-22</date><desc>This is a description WITHOUT line breaks and works fine with split</desc><more_tags>stuff</more_tags></listing> <listing><date>2009-09-22</date><desc>This is a really annoying description field WITH line breaks ... EOF So - I have been reading about "csplit" and it sounds like it might work to solve this issue. I cant seem to get the regular expression right... Basically I want the same output of ~50ish files Something like: *csplit -k myfile.xml '/</listing>/' 25000 {50} Any help would be great Thanks!

  • XSLT: replace an integer by a string

    - by binogure
    I have a little problem. A node in my XML may contains and integer, and i have to replace this integer by a string. Each number match with a string. For example i have: Integer - String 1 - TODO 2 - IN PROGRESS 3 - DONE 4 - ERROR 5 - ABORTED Original XML: <root> <status>1</status> </root> Converted XML: <root> <status>TODO</status> </root> So i want replace 1 by "TODO", 2 by "IN PROGRESS" ... <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/root/status"> <root> <status> <xsl:variable name="text" select="." /> <xsl:choose> <xsl:when test="contains($text, '1')"> <xsl:value-of select="'TODO'"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="$text"/> </xsl:otherwise> </xsl:choose> </status></root> </xsl:template> </xsl:stylesheet> I'am asking if there is another way to do that.
