  • Confusion about maven-war-plugin and jetty-maven-plugin

    - by waxwing
    I am trying to get the run-exploded goal of the jetty-maven-plugin to work correctly. I find the documentation somewhat lacking on what I need to do to set this up. I believe I have a standard WAR-file setup. (The reason I wrote "believe" is that I find the maven-war-plugin documentation lacking as well.) When I build my webapp using maven package, I get the following in my target folder: classes maven-archiver surefire-reports test-classes tmp mywebapp-version mywebapp-version.war where mywebapp-version is the exploded war and mywebapp-version.war is the packaged one. So far so good (I think?). Now, running mvn jetty:run-exploded, it seems the default deploy folder is target/tmp/webapp/mywebapp-version.war/. This folder exists, but contains no files except for a webapp-cache.xml. This seems wrong to me. I also tried to actively set the webApp configuration element to ${project.build.directory}/mywebapp-version/, but run-exploded seems to ignore it (despite the documentation stating otherwise). What am I doing wrong? It looks as if I am missing something simple since no one else appears to be running into the same problem.

  • Dojo addOnLoad, but is Dojo loaded?

    - by adamrice32
    I've encountered what seems like a chicken & egg problem, and have what I think is a logical solution. However, it occurred to me that others must have encountered something similar, so I figured I'd float it out there for the masses. The situation is that I want to use dojo's addOnLoad function to queue up a number of callbacks which should be executed after the DOM has completed rendering on the client side. So what I'm doing is as follows: <html> <head> <script type="text/javascript" src="dojo.xd.js"></script> ... </head> <body> ... <script type="text/javascript"> dojo.addOnLoad( ... ); dojo.addOnLoad( ... ); ... </script> </body> </html> Now, the issue is that I seem to be calling dojo.addOnLoad before the entire Dojo library has been downloaded the browser. This makes sense in a way, because the inline SCRIPT contents should be executed before the entire DOM is loaded (and the normal body onload callback is triggered). My question is this - is my approach sound, or would it make more sense to register a normal/standard body onload JavaScript callback to call a function, which does the same work that each of the dojo.addOnLoads is doing in the SCRIPT block. Of course, this begs the question, why would you ever then use dojo.addOnLoad if you're not guaranteed that the Dojo library will be loaded prior to using the library? Hopefully this situation makes sense to someone other than me. Seems like someone else may have encountered this situation. Thoughts? Best Regards, Adam Rice

  • Converting John Resig's Templating Engine to work with PHP Templates

    - by Serhiy
    I'm trying to convert the John Resig's new ASP.NET Templating Engine to work with PHP. Essentially what I would like to achieve is the ability to use certain Kohana Views via a JavaScript templating engine, that way I can use the same views for both a standard PHP request and a jQuery AJAX request. I'm starting with the basics and would like to be able to convert http://github.com/nje/jquery-tmpl/blob/master/jquery.tmpl.js To work with php like so... <li><a href="{%= link %}">{%= title %}</a> - {%= description %}</li> <li><a href="<?= $link ?>"><?= $title ?></a> - <?= description ?></li> The RexEx in it is a bit over my head and it's apparently not as easy as changing the %} to ? in lines 148 to 158. Any help would be highly appreciated. I'm also not sure of how to take care of the $ difference that PHP variables have. Thanks, Serhiy

  • Open source Java CMS for Google App Engine?

    - by markvgti
    I am looking for an open source Java CMS (Web CMS, actually) to run on Google App Engine. I have looked at related older questions on this topic (What CMS runs on Google AppEngine?, CMS over Google App Engine, with SEO etc.) but the problem is that they all largely list Python-based CMSes. Plus these questions are pretty old, and since GAE is a fast-moving target, I thought it might be worthwhile to ask again. I want a CMS for creating some websites (for myself and for others), but would rather not start writing one from scratch. A "good" (very subjective, I know) open source WCMS allows me to start using a product, while still being able to add to/extend the product/project. On the one hand I am looking for a somewhat mature product/project, on the other hand it's easier to start contributing to the development cycle of a young product/project (conflicting, I know :-). Here are some features that would be preferable: [X]HTML/XML/CSS based templating Ability to create multiple blogs Galleries Ability to create a "Downloads" section (is this pretty much standard?) Separate management for digital assets (images, PDFs, binary files etc.) Roles like "Administrator", "Editor", "Contributor" etc. (or their equivalents) Ability to move/reorganize pages Export to PDF Reformat content for printing Is the CMS you are about to suggest especially well-suited to publishing an online book? My idea is that while the book may be offered as a downloadable eBook, the latest, most current version will be the one available on the website.

  • Generating scala AST for recursive method.

    - by scout
    I am generating the scala AST using the following code: val setting = new Settings(error) val reporter = new ConsoleReporter(setting, in, out) { override def displayPrompt = () } val compiler = new Global(setting, reporter) with ASTExtractor{ override def onlyPresentation = true } //setting.PhasesSetting("parser", "parserPhase") val run = new compiler.Run val sourceFiles:List[String] = List("Test.scala") run.compile(sourceFiles.toList) I guess this is the standard code used to run the compiler in the code and generate the AST to work with. The above code worked fine for any valid scala code in Test.scala till now. When I use a recursive function in Test.scala, like def xMethod(x:Int):Int = if(x == 0) -1 else xMethod(x-1) It gives me a java.lang.NullPointerException. The top few lines of the stack trace look like this at scala.tools.nsc.typechecker.Typers$Typer.checkNoDoubleDefsAndAddSynthetics$1(Typers.scala:2170) at scala.tools.nsc.typechecker.Typers$Typer.typedStats(Typers.scala:2196) at scala.tools.nsc.typechecker.Typers$Typer.typedBlock(Typers.scala:1951) at scala.tools.nsc.typechecker.Typers$Typer.typed1(Typers.scala:3815) at scala.tools.nsc.typechecker.Typers$Typer.typed(Typers.scala:4124) at scala.tools.nsc.typechecker.Typers$Typer.typed(Typers.scala:4177) at scala.tools.nsc.transform.TailCalls$TailCallElimination.transform(TailCalls.scala:199) The code works fine for a method like def aMethod(c:Int):Int = { bMethod(c) } def bMethod(x:Int):Int = aMethod(x) Please let me know if recursive functions need any other setting.

  • Detect a white square in a black and white image

    - by gcc
    I saw that question i one web site (cite name like that programm.) then i tried to solve but icannot (not my and myfriend homework ) how can i approach to that one (in program.net no solution there is ) Read black & white image data from standard input, and detect a white square in the image. Output the coordinates of the upper left corner of the square, and the width of the square. In the preliminary work, you can print the output and terminate your program after you detect your first square. If you can't find any square on the image, you will print the string: "NO DETECTION". Input (which represents a 2 by 2 square in the center of a 5 by 4 image): 2 2 5 4 0 0 0 0 0 0 0 255 255 0 0 0 255 255 0 0 0 0 0 0 Output: 3 2 2 Input (more comprehensible format of the image, with the same output): 2 6 4 000 000 000 000 000 000 000 000 255 255 255 000 000 000 000 255 255 000 000 000 000 000 000 000 Output: no detection Input can be: 000 255 255 000 000 000 000 255 255 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 255 255 255 000 000 000 255 255 255 000 000 000 255 255 255 000 000 000 000 000 000 000 If there are two squares detected, we should use the biggest one

  • Winforms MVP with Castle Windsor - DI for subforms?

    - by Paul Kirby
    I'm building a winforms app utilizing passive-view MVP and Castle Windsor as an IoC container. I'm still a little new to dependency injection and MVP, so I'm looking for some clarity... I have a main form which contains a number of user controls, and also will bring up other dialogs (ex. Login, options, etc) as needed. My first question is...should I use constructor injection to get the presenters for these other views into the main view, or should I go back to a Service Locator-type pattern? (which I've been told is a big nono!) Or something else? Second question...the user controls need to communicate back to the main form when they are "completed" (definition of that state varies based on the control). Is there a standard way of hooking these up? I was thinking perhaps just wiring up events between the main presenter and the child presenters, but I'm not sure if this is proper thinking. I'd appreciate any help, it seems that the combination of MVP and IoC in winforms isn't exactly well-documented.

  • Is this error caused by a 64-bit library being accessed by a Java program running in a 32-bit JVM?

    - by Mike
    I'm trying to create a simple Java app that uses JNI to call some native functions. I've followed the examples in the JNI Programming Guide and can't seem to get them to work. I have the following Hello World program, written in Java: class HelloWorld { private native void print(); public static void main(String [] args) { new HelloWorld().print(); } static { System.load("/home/mike/Desktop/libHelloWorld.so"); } } I compile it using javac HelloWorld.java, just like normal. Then I run javah -jni HelloWorld, and finally the following: gcc34 -shared -fpic -o libHelloWorld.so -I/<path to JDK>/include -I/<path to JDK>/include/linux HelloWorld.c gcc34 is the name of the GCC program on my machine here at work (I don't control that) and I obviously place the real path to the JDK in that command. When I run my program, using the standard java HelloWorld, I get an error saying the following: Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/mike/Desktop/libHelloWorld.so: /home/mike/Desktop/libHelloWorld.so: wrong ELF class: ELFCLASS64 (Possible causes: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1778) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1674) at java.lang.Runtime.load0(Runtime.java:770) at java.lang.System.load(System.java:1003) at HelloWorld.<clinit>(HelloWorld.java:8) Could not find the main class: HelloWorld. Program will exit. I know I'm running a 32-bit JVM (and unfortunately, as of right now, I'm not allowed to get a 64-bit JVM). I tried telling GCC to compile in 32-bit mode using the "-m32" option, but we don't have (and again, can't get) what we need for that. Does this sound like a 32/64-bit conflict or something else?

  • Determine whether .NET assemblies were built from the same source

    - by Clayton
    Does anyone know of a way to compare two .NET assemblies to determine whether they were built from the "same" source files? I am aware that there are some differencing utilities available, such as the plugin for Reflector, but I am not interested in viewing differences in a GUI, I just want an automated way to compare a collection of binaries to see whether they were built from the same (or equivalent) source files. I understand that multiple different source files could produce the same IL, and realise that the process would only be sensitive to differences in the IL, not the original source. The main obstacle to just comparing the byte streams for the two assemblies is that .NET includes a field called "MVID" (Module Version Identifier) the assembly. This appears to have a different value for every compilation, so if you build the same code twice the assembly will be different. A related question is, does anyone know how to force the MVID to be the same for each compilation? This would avoid us needing to have a comparison process that is insensitive to differences in the value of the MVID. A consistent MVID would be preferable, as this means that standard checksums could be used. The background behind this is that a third-party company is responsible for independently reviewing and signing off our releases, prior to us being permitted to release to Production. This includes reviewing the source code. They want to independently confirm that the source code we give them matches the binaries that we earlier built, tested and currently plan to deploy. We are looking for a process that allows them to independently build the system from the source we supply them with, and the compare the checksums against the checksums for the binaries we have tested. thanks

  • Using DevIL with Xcode

    - by jak3t
    Hello everyone! I'm trying to use DevIL with XCode but I can't get it to work. I tried using the "standard" method by doing "configure make make install" and using #import <IL/il> but it doesn't work. It identifies the library but I still get some compiling errors: Ld build/Release/cg.app/Contents/MacOS/cg normal i386 cd "/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1" /Developer/usr/bin/g++-4.2 -arch i386 "-L/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1/build/Release" "-F/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1/build/Release" -filelist "/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1/build/CGaula1.build/Release/cg.build/Objects-normal/i386/cg.LinkFileList" -framework Foundation -framework AppKit -framework GLUT -framework OpenGL -framework Cocoa -framework AppKit -o "/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1/build/Release/cg.app/Contents/MacOS/cg" Undefined symbols: "_ilConvertImage", referenced from: terreno() in main.o "_ilGetInteger", referenced from: terreno() in main.o terreno() in main.o terreno() in main.o "_ilLoadImage", referenced from: terreno() in main.o "_ilBindImage", referenced from: terreno() in main.o "_ilGetData", referenced from: terreno() in main.o "_ilInit", referenced from: terreno() in main.o "_ilGenImages", referenced from: terreno() in main.o ld: symbol(s) not found collect2: ld returned 1 exit status` So i tried do it by using the macports libdevil install. It installed correctly but nothing seems to work. Do I need to change my #import declarations? Any suggestion to install DevIL on the Mac correctly and use it in a XCode Project? Thanks a lot!

  • file layout and setuptools configuration for the python bit of a multi-language library

    - by dan mackinlay
    So we're writing a full-text search framework MongoDb. MongoDB is pretty much javascript-native, so we wrote the javascript library first, and it works. Now I'm trying to write a python framework for it, which will be partially in python, but partially use those same stored javascript functions - the javascript functions are an intrinsic part of the library. On the other hand, the javascript framework does not depend on python. since they are pretty intertwined it seems like it's worthwhile keeping them in the same repository. I'm trying to work out a way of structuring the whole project to give the javascript and python frameworks equal status (maybe a ruby driver or whatever in the future?), but still allow the python library to install nicely. Currently it looks like this: (simplified a little) javascript/jstest/test1.js javascript/mongo-fulltext/search.js javascript/mongo-fulltext/util.js python/docs/indext.rst python/tests/search_test.py python/tests/__init__.py python/mongofulltextsearch/__init__.py python/mongofulltextsearch/mongo_search.py python/mongofulltextsearch/util.py python/setup.py I've skipped out a few files for simplicity, but you get the general idea; it' a pretty much standard python project... except that it depends critcally ona whole bunch of javascript which is stored in a sibling directory tree. What's the preferred setup for dealing with this kind of thing when it comes to setuptools? I can work out how to use package_data etc to install data files that live inside my python project as per the setuptools docs. The problem is if i want to use setuptools to install stuff, including the javascript files from outside the python code tree, and then also access them in a consistent way when I'm developing the python code and when it is easy_installed to someone's site. Is that supported behaviour for setuptools? Should i be using paver or distutils2 or Distribute or something? (basic distutils is not an option; the whole reason I'm doing this is to enable requirements tracking) How should i be reading the contents of those files into python scripts?

  • Automatic linebreak in WPF label

    - by Vlad
    Dear all, is it possible for a WPF Label to split itself automatically into several lines? In my following example, the text is cropped at the right. <Window x:Class="..." xmlns="..." xmlns:x="..." Height="300" Width="300"> <Grid> <Label> `_Twas brillig, and the slithy toves did gyre and gimble in the wabe: all mimsy were the borogoves, and the mome raths outgrabe.</Label> </Grid> </Window> Am I doing something wrong? Taking other controls is unfortunately not a good option, since I need support of access keys. Replacing the Label with a TextBlock (having TextWrapping="Wrap"), and adjusting its control template to recognize access keys would be perhaps a solution, but isn't it an overkill? Edit: having a non-standard style for label will break skinning, so I would like to avoid it if possible.

  • Core Data Migration - "Can't add source store" error

    - by Tofrizer
    Hi, In my iPhone app I'm using Core Data and I've made changes to my data model that cannot be automatically migrated over (i.e. added new relationships). I added the data model version (Design - Data Model - Add Model Version) and applied my new data model changes to the new version 2. I then created a mapping object model and set the Source and Destination models to their correct data models (old and new respectively). When I run the app and call the persistentStoreCoordinator, my app barfs with the following: 2010-02-27 02:40:30.922 XXXX[73578:20b] Unresolved error Error Domain=NSCocoaErrorDomain Code=134110 UserInfo=0xfc2240 "Operation could not be completed. (Cocoa error 134110.)", { NSUnderlyingError = Error Domain=NSCocoaErrorDomain Code=134130 UserInfo=0xfbb3a0 "Operation could not be completed. (Cocoa error 134130.)"; reason = "Can't add source store"; } FWIW (not much i think) I've also made the usual code changes in persistentStoreCoordinator to use the NSMigratePersistentStoresAutomaticallyOption and NSInferMappingModelAutomaticallyOption (for future data model changes that can be automatically migrated). More relevantly, my managedObjectModel is created by calling initWithContentsOfURL where the file/resource type is "momd". I've tried updating both the source and destination model in the mapping model (Design - Mapping Model - Update XXX Model) as well as deleted the mapping model and recreated it. I've cleaned and re-built but all to no avail. I still get the above error message. Any pointers/thoughts on how I can further debug or resolve this problem please? I haven't posted any code snippets because this feels much more like a build environment issue (and my code is very standard - just the usual core data code to handle migrations using a mapping model but I'm happy to show the code if it helps). Appreciate any help. Thanks

  • Formatting and pretty printing dates with jquery

    - by Tauren
    I need to display dates in a couple different ways in an app built with jquery. In some situations, I need the typical "yyyy-mm-dd hh:mma" type of formatting, with all of it's different permutations. In other cases, I need to show dates "pretty printed" similar to how StackOverflow does them: 5 seconds ago 12 minutes ago 3 hours ago yesterday 2 days ago My application already uses JQuery UI DatePicker which includes a formatDate() function, but as far as I can tell, there is no way to use it outside of the datepicker. I want to format dates that aren't associated with a datepicker. Is it possible to do this using DatePicker? The DateJS library can parse dates like "12 minutes ago", but as far as I can tell, it cannot take a Date object and format strings like this. It can format the typical "yyyy-mm-dd" types of formats. This library seems pretty heavy as well. John Resig's Pretty Dates looks like it can provide the pretty printing ("2 hours ago"), but it doesn't do the standard formatting. Is there not a single plugin that can do all of this? Is there a way to leverage the DatePicker code so I don't have to load multiple codebases that do the same things?

  • Currency exchange rates for paypal

    - by Jacco
    Does anyone know a way to get the currency exchange rates for paypal? We have custom shopping cart and use Paypal (Website Payments Standard) to handle payments. Our 'home' currency is Euro, but we would like to present our customers the option to pay in different currencies (USD, CAD, AUD and GBP). PayPal offers the option to:     a) automatically convert our Euro quoted prices to, for example, USD upon checkout     b) checkout in USD directly With option a): We get paid in Euro, the customer pays for the currency exchange (good). The customer does not know what he/she is going to be charged in USD until checkout. (bad) With option b) The customer pays in USD, then the currency is converted into EUR and we pay the the currency exchange. The customer never has to worry about the different currencies (excellent) We do not know the exchange rate PayPal is going to use so we cannot quote the correct prices to our customer (showstopper) So my question is:   Does anybody know a way to get the PayPal exchange rates? or   Does anybody know how to make a good estimate? Update: PayPal updates it's exchange rate 2 times a day. (at least, that is what they state). They use the Interbank Exchange Rate provided by ??? and add a 2.5% spread above this rate to determine their retail foreign exchange rates. Unforunately, there the Interbank Exchange Rates vary from source to source and from minute to minute. We have been monitoring the PayPal exchange rates and cross referenced them with the Official reference rates provides by the European Central Bank. the results vary widely, somewhere from 1 to 6 ! percent...

  • Best Youtube embed player sizes?

    - by Xeoncross
    I use tumblr to share videos and, unfortunately, when re-posting a video to your tumblelog it uses the embed code at 400x336px. This is neither widescreen nor very large. So I'm trying to set the player to better size and I'm finding that the youtube player really comes in many sizes. For example, when copying the embed code for and HD video I get the sizes 560x340, 640x385, and 853x505. Then when I look at the embed code for a SD video I get the sizes 425x344, 480x385, and 640x505. I was having the best luck with setting the player to 640 x 505 as it was large enough for HD and perfect for SD. print str_replace( array('400', '336'), array('640', '505'), $video_player_html); Has anyone dealt with trying to find a good standard embed size for a site? One thing that would make this a lot easier is to know whether the video was HD or not - however, that info is not provided in the embed code. I guess I am actually more interested in knowing the right ratio (or specific size) to use that works the best for youtube's mixed content.

What I've got so far: First, I'm defining a custom ActivityDesignerTheme as follows: public class CustomActivityTheme : ActivityDesignerTheme { public CustomActivityTheme(WorkflowTheme theme) : base(theme) { this.BackColorStart = Color.FromArgb(0xff, 0xf4, 0xf4, 0xf4); this.BackColorEnd = Color.FromArgb(0xff, 0xc0, 0xc0, 0xc0); this.BackgroundStyle = LinearGradientMode.Horizontal; } } Then, I am applying this theme to a custom ActivityDesigner (apparently the theme must be applied to a designer, and not to an activity): [ActivityDesignerTheme(typeof(CustomActivityTheme))] public class CustomActivityDesigner : SequentialActivityDesigner { ... } Ultimately, I am applying the custom designer to my custom Activity: [Designer(typeof(CustomActivityDesigner))] public partial class CustomActivity : SequenceActivity { ... } Now, according to some code examples that I've seen, this should do the trick. However, when I include an instance of my CustomActivity in a workflow, my custom theme is not applied and it is displayed in the Visual Studio Designer as any standard activity would (white background etc.). I tried re-compiling and even re-starting Visual Studio a couple of times, just to make sure the used assembly is up-to-date, but to no avail. My question: What am I missing? Why does Visual Studio's Workflow Designer not respect the CustomActivityTheme when it displays a CustomActivity?

  • File Format Conversion to TIFF. Some issues???

    - by Nains
    I'm having a proprietary image format SNG( a proprietary format) which is having a countinous array of Image data along with Image meta information in seperate HDR file. Now I need to convert this SNG format to a Standard TIFF 6.0 Format. So I studied the TIFF format i.e. about its Header, Image File Directories( IFD's) and Stripped Image Data. Now I have few concerns about this conversion. Please assist me. SNG Continous Data vs TIFF Stripped Data: Should I convert SNG Data to TIFF as a continous data in one Strip( data load/edit time problem?) OR make logical StripOffsets of the SNG Image data. SNG Data Header uses only necessary Meta Information, thus while converting the SNG to TIFF, some information can’t be retrieved such as NewSubFileType, Software Tag etc. So this raises a concern that after conversion whether any missing directory information such as NewSubFileType, Software Tag etc is necessary and sufficient condition for TIFF File. Encoding of each pixel component of RGB Sample in SNG data: Here each SNG Image Data Strip per Pixel component is encoded as: Out^[i] := round( LineBuffer^[i * 3] * **0.072169** + LineBuffer^[i * 3 + 1] * **0.715160** + LineBuffer^[i * 3+ 2]* **0.212671**); Only way I deduce from it is that each Pixel is represented with 3 RGB component and some coefficient is multiplied with each component to make the SNG Viewer work RGB color information of SNG Image Data. (Developer who earlier work on this left, now i am following the trace :)) Thus while converting this to TIFF, the decoding the same needs to be done. This raises a concern that the how RBG information in TIFF is produced, or better do we need this information?. Please assist...

  • SQL Compact error: Unable to load DLL 'sqlceme35.dll'. The specified module could not be found

    - by Ciaran Bruen
    Hi - I'm developing a Winforms application using Visual Studio 2008 C# that uses a SQL compact 3.5 database on the client. The client will most likely be 32 bit XP or Vista machines. I'm using a standard Windows Installer project that creates an msi file and setup.exe to install the app on a client machine. I'm new to SQL compact so I haven't had to distribute a client database like this before now. When I run the setup.exe (on new Windows XP 32 bit with SP2 and IE 7) it installs fine but when I run the app I get the error below: Unable to load DLL 'sqlceme35.dll'. The specified module could not be found I spent a few hours searching this error already but all I can find are issues relating to installing on 64 bit Windows, none relating to normal 32 bit that I'm using. The install app copies the all the dependant files that it found into the specified install directory, including the System.Data.SqlServerCe.dll file (assembly version 3.5.1.0). The database file is in a directory called 'data' off the application directory, and the connection string for it is <add name="Tickets.ieOutlet.Properties.Settings.TicketsLocalConnectionString" connectionString="Data Source=|DataDirectory|\data\TicketsLocal.sdf" providerName="Microsoft.SqlServerCe.Client.3.5" /> Some questions I have: should the app be able to find the dll if it's in the same directory i.e. local to the app, or do I need to install it in the GAC? (If so cam I use the Windows Installer to install a dll in the GAC?) is there anything else I need to distribute with the app in order to use a Sql Compact database? there are other dlls also such as MS interop for exporting data to Excel on the client. Do these need to be installed in the GAC or will locating them in the application directory suffice? TIA, Ciaran.

  • finding "line-breaks" in textarea that is word-wrapping ARABIC text

    - by Irfan jamal
    I have a string of text that I display in a textarea (right-to-left orientation). The user can resize the textarea dynamically (I use jquery for this) and the text will wrap as necessary. When the user hits submit, I will take that text and create an image using PHP, BUT before submitting I would like to know where the "line-breaks" or rather "word-wraps" occur. Everywhere I have looked so far only shows me how to process line-breaks on the php side. I want to make it clear that there ARE NO LINE-BREAKS. What I have is one LONG string that will be word-wrapped in different ways based on the width of the textarea set by the user. I can't use "columns" or any other standard width representation because I have a very complex arabic font that is actually composed of glyphs (characters) of numerous different widths. If anyone knows of a way of accessing where the word wraps occur (either in a textarea or a div if need-be), I'd really like to know. My only other solution is to actually store (in my DB) the width of every single character (somewhat tedious since there are over 200 characters in 600 different fonts, for a total of...some huge number). My hopes aren't high, but I thought I would ask. Thanks i. jamal

  • Best practice for structuring a new large ASP.NET MVC2 plus EF4 VS2010 solution?

    - by Nick
    Hi, we are building a new web application using Microsoft ASP.NET MVC2 and Entity Framework 4. Although I am sure there is not one right answer to my question, we are struggling to agree a VS2010 solution structure. The application will use SQL Server 2008 with a possible future Azure cloud version. We are using EF4 with T4 POCOs (model-first) and accessing a number of third-party web-services. We will also be connecting to a number of external messaging systems. UI is based on standard ASP.NET (MVC) with jQuery. In future we may deliver a Silverlight/WPF version - as well as mobile. So put simply, we start with a VS2010 blank solution - then what? I have suggested 4 folders Data (the EF edmx file etc), Domain (entities, repositories), Services (web-services access), Presentation (web ui etc). However under Presentation, creating the ASP.NET MVC2 project obviously creates it's own Models folder etc and it just doesn't seem to fit too well in this proposed structure. I'm also missing a business layer (or does this sit in the domain?). Again I am sure there is no one right way to do it, but I'd really appreciate your views on this. Thanks

  • Implementing Naïve Bayes algorithm in Java - Need some guidance

    - by techventure
    hello stackflow people As a School assignment i'm required to implement Naïve Bayes algorithm which i am intending to do in Java. In trying to understand how its done, i've read the book "Data Mining - Practical Machine Learning Tools and Techniques" which has a section on this topic but am still unsure on some primary points that are blocking my progress. Since i'm seeking guidance not solution in here, i'll tell you guys what i thinking in my head, what i think is the correct approach and in return ask for correction/guidance which will very much be appreciated. please note that i am an absolute beginner on Naïve Bayes algorithm, Data mining and in general programming so you might see stupid comments/calculations below: The training data set i'm given has 4 attributes/features that are numeric and normalized(in range[0 1]) using Weka (no missing values)and one nominal class(yes/no) 1) The data coming from a csv file is numeric HENCE * Given the attributes are numeric i use PDF (probability density function) formula. + To calculate the PDF in java i first separate the attributes based on whether they're in class yes or class no and hold them into different array (array class yes and array class no) + Then calculate the mean(sum of the values in row / number of values in that row) and standard divination for each of the 4 attributes (columns) of each class + Now to find PDF of a given value(n) i do (n-mean)^2/(2*SD^2), + Then to find P( yes | E) and P( no | E) i multiply the PDF value of all 4 given attributes and compare which is larger, which indicates the class it belongs to In temrs of Java, i'm using ArrayList of ArrayList and Double to store the attribute values. lastly i'm unsure how to to get new data? Should i ask for input file (like csv) or command prompt and ask for 4 values? I'll stop here for now (do have more questions) but I'm worried this won't get any responses given how long its got. I will really appreciate for those that give their time reading my problems and comment.

  • How to produce an HTTP 403-equivalent WCF Message from an IErrorHandler?

    - by Andras Zoltan
    I want to write an IErrorHandler implementation that will handle AuthenticationException instances (a proprietary type), and then in the implementation of ProvideFault provide a traditional Http Response with a status code of 403 as the fault message. So far I have my first best guess wired into a service, but WCF appears to be ignoring the output message completely, even though the error handler is being called. At the moment, the code looks like this: public class AuthWeb403ErrorHandler : IErrorHandler { #region IErrorHandler Members public bool HandleError(Exception error) { return error is AuthenticationException; } public void ProvideFault(Exception error, MessageVersion version, ref Message fault) { //first attempt - just a stab in the dark, really HttpResponseMessageProperty property = new HttpResponseMessageProperty(); property.SuppressEntityBody = true; property.StatusCode = System.Net.HttpStatusCode.Forbidden; property.StatusDescription = "Forbidden"; var m = Message.CreateMessage(version, null); m.Properties[HttpResponseMessageProperty.Name] = property; fault = m; } #endregion } With this in place, I just get the standard WCF html 'The server encountered an error processing the request. See server logs for more details.' - which is what would happen if there was no IErrorHandler. Is this a feature of the behaviours added by WebServiceHost? Or is it because the message I'm building is simply wrong!? I can verify that the event log is indeed not receiving anything. My current test environment is a WebGet method (both XML and Json) hosted in a service that is created with the WebServiceHostFactory, and Asp.Net compatibility switched off. The service method simply throws the exception in question.
