  • What are the common patterns in web programming?

    - by lankerisms
    I have been trying to write my first big web app (more than one cgi file) and as I kept moving forward with the rough prototype, paralelly trying to predict more tasks, this is the todo that got accumulated (In no particular order). * Validations and input sanitizations * Object versioning (to avoid edit conflicts. I dont want hard locks) * Exception handling * memcache * xss and injection protections * javascript * html * ACLs * phonetics in search, match and find duplicates (for form validation) * Ajaxify!!! (I have snipped off the project specific items.) I know that each todo will be quite tied up to its project and technologies used. What I am wondering though, is if there is a pattern in your todo items as well as the sequence in which you experienced guys have come across them.

  • Access to a single pixel in C#

    - by Malki
    Hello, I'm working on a school project right now. It's meant to be a 3D editing software, (like a very minimized version of Maya). I have to write it in C#, using the 'Windows Application Project'. I intend to implement all the 3D stuff myself, from projections to shading. My question is, how can I get direct access to a single pixel in the C# windows application? I know I'm going to have a main view port in the window. But I haven't decided yet how it will be made. Is there a built in object that I can use, that will let me define the boundaries of the view port, and then paint each pixel individually? (I'm just shooting in the dark here, I don't know much about C#. I mostly program in C) Thanks, Malki.

  • Problem with connectionstring and entityframework

    - by Masna
    Hello, I have a database (sql 2008 mdf file), a class library project with an edmx file, created with the wizard. So the connection string is also made by the wizard. This project is on a teamfoundation server. I can use all the wizard made objects when coding. But when i run the program and I try to make an entityContainerName, the program crashes and gives this error: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. on this line: public TestEntities() : base("name=TestEntities", "TestEntities") How can I solve this problem or what am I doing wrong?

  • Asp.net Report Viewer - Custom filter parameters

    - by Chris
    Hi all, for a data warehouse project I need to know about some best practices regarding custom report viewer filters/parameters. Usually I use the standard parameter feature for reports, like multiple select boxes, check boxes, text boxes etc.. But for the current project some reports require more complex report parameters. E.g. a user wants to analyze some measures. For that the user needs to set a filter on a specific address. There are over 100.000 address to choose from, so he has to have the ability to search for an address (full text). Since such features cannot be done with the standard parameters, I will have to create custom params within a ASPX page which are then passed to the report viewer control. So my question is: Are there any best practices on how to create custom parameters? Did anyone had similar problems, if so, how did you solve it?

  • Linkedin: Registering Application for both Web and Mobile

    - by VishwaKumar
    My project deals with both Web app and Mobile app. So before we can use Linkedin API's into our project we need to register our app with Linkedin according to this Quick Start. But for my situation where i use Linkedin API's for both web and mobile, Do i need to register two application with Linkedin. Or is there any other way to register a single application and use the same for both web and mobile? In the registration page i don't see any distinction for Web and Mobile, unlike facebook where a single application registered can be used for both web and mobile app. If anyone could point me to appropriate docs or pointers, it would be really helpful. Please forgive me for posting here as there wasn't any appropriate forum to choose from. Thank you.

  • Universal syntax file format?

    - by Isaiah
    Hey as a project to improve my programing skills I've begun programing a nice code editor in python to teach myself project management, version control, and gui programming. I was wanting to utilize syntax files made for other programs so I could have a large collection already. I was wondering if there was any kind of universal syntax file format much in the same sense as .odt files. I heard of one once in a forum, it had a website, but I can't remember it now. If not I may just try to use gedit syntax files or geany. thanks

  • EntityDataSource Unable to configure to Entity Model

    - by photo_tom
    I'm doing my first test asp.net3.5 app using EntityDataSource. I've got the basic project built and the Entity model created and compiled. Database is a local sqlexpress one in app_data directory. When I put the <asp:EntityDataSource /> control on the page and try to configure it, I'm getting the message "The list of named connections could not be loaded because the configuration could not be opened". At this point, everything in the project is "auto-created" by Visual Studio 2008sp1. I confused as I cannot find any information on how to correct from this message.

  • MS WebBrowser + Embedded HTML Resource + res:// Protocol

    - by letthewookiewin
    Hi, I have an embedded HTML resource (helloworld.htm) inside my Visual Studio project. (Ie, I've added an HTML file to the project and set its properties to "Embedded Resource". Within the same application I have a WebBrowser control. I'd like to direct the WebBrowser control to display the HTML resource using the res:// protocol. But I can't figure out the exact format needed to address an embedded resource using this style of URL. Any ideas? Thanks!

  • How to commit a non-subversioned file into a repository ?

    - by devdude
    The environment: SVN, Netbeans, Hudson SVN Project A: Builds a library file (foo.jar). The build file is under /dist, which is ignored for svn, the sourcecode is under svn control. SVN Project B: holds all library files. (other SVN projects get all their libraries from here via external svn) Question: I want to commit foo.jar from A into B. How to do that ? foo.jar cannot be added or committed because it is not under SVN control. Thanks for any hints ! (The question is independent from the IDE and CI Server)

  • Maven : Is it possible to override the configuration of a plugin already defined for a profile in a parent POM

    - by Guillaume Cernier
    In a POM parent file of my project, I have such a profile defining some configurations useful for this project (so that I can't get rid of this parent POM) : <profile> <id>wls7</id> ... <build> <plugins> <!-- use java 1.4 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <fork>true</fork> <source>1.4</source> <target>1.4</target> <meminitial>128m</meminitial> <maxmem>1024m</maxmem> <executable>%${jdk14.executable}</executable> </configuration> </plugin> </plugins> </build> ... </profile> But in my project I just would like to override the configuration of the maven-compiler-plugin in order to use jdk5 instead of jdk4 for compiling test-classes. That's why I did this section in the POM of my project : <profiles> <profile> <id>wls7</id> <activation> <property> <name>jdk</name> <value>4</value> </property> </activation> <build> <directory>target-1.4</directory> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <executions> <execution> <id>my-testCompile</id> <phase>test-compile</phase> <goals> <goal>testCompile</goal> </goals> <configuration> <fork>true</fork> <executable>${jdk15.executable}</executable> <compilerVersion>1.5</compilerVersion> <source>1.5</source> <target>1.5</target> <verbose>true</verbose> </configuration> </execution> </executions> </plugin> </plugins> </build> </profile> ... </profiles> and it's not working ... I even tried to override the configuration in regular plugin sections of my POM (I mean, not for a specific profile but for my whole POM). What could be the problem ? To clarify some of my requirements : I don't want to get rid of the parent POM and the profile (wls7) defined inside it (since I need many and many properties, configurations, ...) and that is not the process in my company. A solution based on duplicating the parent POM and/or the profile defined inside it is not a good one. Since if the responsible of the parent POM change something, I would have to report it in mine. It's just an inheritance matter (extend or override a profile, a configuration from an upper-level POM) so I think it should be possible with maven2.

  • C++ app fails to initialize (0xc0000005), when using C# dll

    - by Simon
    Hi, I have a C# DLL, which I call from a native C++ programm. As I use Qt and /clr compiler option did not work I followed this tutorial for a bridge. So I have a VS2008 project (compiled with /clr), which links to the C# DLL and contains the bridge class and the native class, which exposes interfaces to my C++ programm. Another VS2008 project (no .net stuff) calls the native class (statically linked). I had some issues, but now the programm at least compiles. However, if I try to run this programm, I get a (0xc0000005) error on initialization, when I try to use the native class. As this happens on initialization, I don't even see, which DLLs fail to initialize. All DLLs should be in the right place. Any hints? Thank you.

  • How to stop C# compile on first error in VS 2010 (VS 2008 macros don't work)!

    - by Ben Robbins
    At work we have a C# solution with over 80 projects. Is it possible in VS 2010 to automatically stop compilation as soon as an error is encountered rather than the default behaviour which is to continue as far as possible and display a list of errors in the error window? I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). I'd also note that in VS 2008 we used macros similar to some of the answers below but they don't work in VS 2010 (at least I couldn't get them to as the environment events don't seem to fire in VS 2010).

  • How to integrate ANTLR (2.7) in Visual Studio 2005 (C++) build?

    - by Burkhard
    I have a project containing files generated from a .g file (antlr 2.7.x). The guy who wrote the whole thing has left me with it. Until now, I did not need to modify the grammar and all was fine. But now, I cannot continue without modifying the grammar (i.e. the .g-file). I have the source code of the used antlr and the visual studio 2005 project. Unfortunately, the lexer and parser files are not generated prior to the build (in fact they are never generated) and that leads to my question: how do I generate these files whenever the grammar file is modified? Or in other words, how do I integrate antlr into visual studio?

  • Zend Framework on a Shared Host

    - by manyxcxi
    I am trying to push my first ZF project to my shared hosting provider. I have done a lot of testing on my home server and everything is working great. My issue is that I do not know how to set up my .htaccess files on the shared hosting provider to make it work correctly. The ZF documentation says to configure my Apache config VirtualServer DocumentRoot to /whatever/path/project-folder/public, but I don't have that kind of access. How do I get around this? I have seen http://stackoverflow.com/questions/1115547/zend-framework-on-shared-hosting but none of those solutions have worked for me. My application path looks like this / - .htaccess - /application ... - /public -- .htaccess -- index.php -- ... ... My .htaccess files look like: /.htaccess RewriteEngine On RewriteRule !\.(js|gif|jpg|png|css|txt)$ public/index.php [L] RewriteCond %{REQUEST_URI} !^/public/ RewriteRule ^(.*)$ public/$1 [L] /public/.htaccess RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L]

  • How to set utf8 in the auto-generated PHP code of flash builder 4 ?

    - by Mark
    HI, PHP problem here (I think): I've just created a Flex (Flash Builder) project with a datagrid linked to a database - the database is all utf8. When I run the project using the auto-generated code in flex4, the non-English part comes like ????? while the English part comes fine. The auto-generated PHP code uses mysqli. I've tried: $this->connection->set_charset('utf8'); or mysqli_query($this->connection,"SET NAMES utf8"); I also tried writing the code myself (I'm not a PHP guy): mysql_query("set names utf8"); was fine - but that's mysql and not mysqli (that's an "i" after the mysql) and I want to use the auto-generated code... any help is appreciated.

  • How can I add a .jar to my build path in Eclipse?

    - by Roman
    I try to do it the following way: Right click on the name of the project. Click on Build Path in the drop dawn menu. Click on "Configure Build Path" And then I do not know what to do. Should I select "Source", "Projects", "Libraries", "Order and Export"? In "Libraries" I have "Add JARs..." and "Add External JARs...". What should I select? (I have already a .jar file in the lib folder of my project.) ADDED: If I click on "Add JARs" in the "Libraries" tab, I see the "lib" sub-folder but if I go there I do not see my .jar file there (and I know that it is there).

  • Learning rails and AJAX. How do I load a div via ajax and then toggle hiding/showing it?

    - by Kevin L.
    I'm doing my first Ruby on Rails project. I am working on a project where the user can add a new message. Then they can add updates to this message like a thread. I've got it all written and now I'm going back and applying some AJAX. I want to show just the main message when the page first loads. Then when I click a link I want an AJAX event to fire that populates a div with all the updates to the message. Then I want this same link to toggle hiding and showing the div. I've made a submit button to fire the ajax and get back the updates using form_remote_tag. I've also created a separate link to toggle the hiding using $(div_id).toggle();. But now I'm stuck on how to combine these two things into one all purpose link. Thanks.

  • Looking for Info on a Javascript Testing framework

    - by DaveDev
    Hi Can somebody fill me in on JavaScript Testing Frameworks? I'm working on a project now and as the JS (Mostly jQuery) libraries grow, it's getting more and more difficult to introduce change or refactor, because I have no way of guaranteeing the accuracy of the code without manually testing everything. I don't really know anything about JavaScript Testing Frameworks, or how they integrate/operate in a .Net project, so I thought I'd ask here. What would a good testing framework be for .Net? What does a JavaScript test look like? (e.g. with NUnit, I have [TestFixture] classes & [Test] methods in a ProjectTests assembly) How do I run a javascript test? What are the conceptual differences between testing JS & testing C#? Is there anything else that would be worth knowing? Thanks Dave
