  • Concepts a web application developer should know?

    - by iama
    I think it is imperative for web application developers to know the answers surrounding the following general questions on web development irrespective of the programming language/framework used. What authentication mechanisms HTTP offer & what are their pros and cons? Why should one go for FORMS authentication? How to secure authentication or for that matter any transactions via HTTP? How to maintain state in HTTP? What are the downsides to maintaining state via cookie & what happens when browsers disable them? Security issues like cross site scripting, session hijacking etc. What other questions a web developer should have answers for similar to the ones above that are programming language/web framework agnostic?

  • Linker library for OpenMP for Snow Leopard?

    - by unknownthreat
    Currently, I am trying out OpenMP on XCode 3.2.2 on Snow Leopard: #include <omp.h> #include <iostream> #include <stdio.h> int main (int argc, char * const argv[]) { #pragma omp parallel printf("Hello from thread %d, nthreads %d\n", omp_get_thread_num(), omp_get_num_threads()); return 0; } I didn't include any linking libraries yet, so the linker complains: "_omp_get_thread_num", referenced from: _main in main.o "_omp_get_num_threads", referenced from: _main in main.o OK, fine, no problem, I take a look in the existing framework, looking for keywords such as openmp or omp... here comes the problem, where is the linking library? Or should I say, what is the name of the linking library for openMP? Is it dylib, framework or what? Or do I need to get it from somewhere first?

  • Setting up functional Tests in Flex

    - by Dan Monego
    I'm setting up a functional test suite for an application that loads an external configuration file. Right now, I'm using flexunit's addAsync function to load it and then again to test if the contents point to services that exist and can be accessed. The trouble with this is that having this kind of two (or more) stage method means that I'm running all of my tests in the context of one test with dozens of asserts, which seems like a kind of degenerate way to use the framework, and makes bugs harder to find. Is there a way to have something like an asynchronous setup? Is there another testing framework that handles this better?

  • Creating a data driven web front end quickly

    - by Ilya
    Over the last few years, I can't count how many web front ends I've had to create over a relatively simple database schema to fasciliate data entry. I have to imagine that someone out there has written a framework I can use to simplify the creation of these kind of simple GUIs. Doing a quick google, the following look like the key players in .net: ASP.Net dynamic data framework SubSonic NakedObjects for .net Has anyone worked with any of these and have any preferences? More importantly, are there other frameworks that would be good to evaluate in this space?

  • Multiple Inheritance in LINQtoSQL?

    - by Bumble Bee
    Guys, I have been surfing thru the web to find a way that I could use Multiple-Table-Inheritance in LINQ-To-SQL. But it looks like that it only supports single table inheritance which is not the best way to achieve inheritance in a ORM framework. I got to read that this will be addressed in next LINQ and Entity framework implementations. But how longer a stay we are talking about? In the meantime, if any of you guys have tried out a work-around implementation to achieve this, please let me know. And I thought of using my leisure time to come up with such an implementation so suggestions are welcome! /Bumble Bee

  • turning open source software into a consulting business ?

    - by sofreakinghigh
    just some general and specific questions about running a business which uses open source software and sells training, services, and other value added solutions utilizing the open source asset(s). 1) how much modification do you need to make to an existing open source software/framework to give a new brand ? open source (GPLv3) branding issues here.... for ex) Mambo and Joomla, i think they are pretty much same ? but they have different labels. 2) Is there a disadvantage of promoting open source software/framework/suite in hopes of selling value added services and solutions on top of the Open source asset ? 3) can Open source assets be marketing point for lowered Total Ownership Cost and transparency ? meaning, clients will not be using some mysterious, opaque proprietary asset ? 4) is competition fierce? cost of developing software is non existing because you are using an open source asset. barrier to entry is minimal ??

  • "Unable to find a version of the runtime to run this application" running .NET app in virtual XP mac

    - by Pete
    I've written a few winform apps in .net 2.0 which won't run in a virtual XP (running from VirtualBox). I get the error "unable to find a version of the runtime to run this application" (.NET Framework Initialization Error). I've tried fixing the installation of .net and also installing v3.5. I think it's probably a security issue rather than a framework problem, but i'm running under an administrator account. Other .net apps (2.0) run ok, so it might be a strong name/signing problem. I've tried compiling them completely unsigned and also delay signing them with a key and turning on verification skipping with the sn tool. help greatly appreciated!

  • How do I use a command line tool to install .net 4 to IIS

    - by tehp
    I'm trying to deploy my WCF RIA services application to our in-house server for testing. I've been following the instructions and comments from this blog site: http://timheuer.com/blog/archive/2009/12/10/tips-to-deploy-ria-services-troubleshoot.aspx At the end someone points to this question: http://stackoverflow.com/questions/1528324/how-to-solve-a-http-error-404-3-not-found-error I've been trying to run that same tool with .net 4.0 but it keeps giving me an error: [Warning]The HTTP namespace reservation already exists. I am running the version of the exe that I found inside of C:\Windows\Microsoft.NET\Framework\v4.0.21006 There is also C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation that has (what I assume is) the same exe in it, and I can use it just fine. I've tried to un-install the 3.0 version before installing the 4.0 version, but I am still getting the same warning and failure. Has anyone successfully done this with .net 4.0?

  • Is dependency injection possible for JSP beans?

    - by kazanaki
    This may be a long shot question.. I am working on an application that is based on JSP/Javascript only (without a Web framework!) Is there a way to have depencency injection for JSP beans? By jsp beans I mean beans defined like this <jsp:useBean id="cart" scope="session" class="session.Carts" /> Is there a way/library/hack to intercept the bean creation so that when "cart" is referenced for the first time, some some of injection takes place? Can I define somewhere a "listener" for JSP beans (like you can do for JSF beans for example)? I am free to do anything I want in the back-end, but I cannot add a web framework in the front-end (Don't ask!)

  • Curious about python installation paths, especially on OSX.

    - by chiggsy
    First: I'm running Macports. No problems with that, except: /opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin which is the value of sys.exec_prefix, for my macports python even though: /opt/local/lib/python2.6/site-packages/ seems to be quite a logical place to put things, /opt/local being the macports --prefix, as it were. Why does easy_install put things in this odd Frameworks/Python.framework thing? More importantly, can i use the methods here, to ensure that all my systemwide python, particularly the scripts which I really want in /opt/local/bin, things I use all over the place like (i|b)python for example are accessible?

  • Is there a predefined enumeration for Month in the .NET library?

    - by Mark Rogers
    I'm looking to see if there is an official enumeration for months in the .net framework. It seems possible to me that there is one, because of how common the use of month is, and because there are other such enumerations in the .net framework. For instance, there is an enumeration for the days in the week, System.DayOfWeek, which includes monday, tuesday, etc.. I'm wondering if there is one for the months in the year, ie. January, February, etc? Does anyone know? Thanks for reading!

  • CMIS explorer webapp

    - by Nicolas Raoul
    CMIS is a recently approved standard for accessing ECM repositories. My idea is to create a repository explorer using CMIS, under the form of an open source Java/JEE Web Application. The main interest would probably be for integrators, using it as a framework on which to quickly build repository access intranet/extranet applications. Of course, if such an open source project already exists, I would rather contribute to it rather than start a competing effort. So, does such an application/framework already exist? As open source? The only one I have found so far is chemistry-opencmis-test-browser, which is intended for tests and seems really inconvenient to extend for business use (no MVC, no IoC).

  • ASP.net error message when using REST starter kit

    - by jonhobbs
    Hi all, I've written some code using the REST starter kit and it works fine on my development machine. However, when I upload it to our server the page gives me the following error message... CS1684: Warning as Error: Reference to type 'System.Runtime.Serialization.Json.DataContractJsonSerializer' claims it is defined in 'c:\WINNT\assembly\GAC_MSIL\System.ServiceModel.Web\3.5.0.0__31bf3856ad364e35\System.ServiceModel.Web.dll', but it could not be found I've removed code line by line and it appears that the following line of code is triggering the error... HttpContent newOrganizationContent = HttpContentExtensions.CreateXmlSerializable(newOrganizationXml); Really haven't got a clue how to fix it. I assumed it might be because it needs a newer version of the framework to run, but looking in IIS it says it's running version 2.0.50727 which I think is the lates version because it says that even when we're using framework 3.5 Very confused, any ideas?

  • Quickly generate/publish RSS feeds from ASP.NET projects?

    - by jdk
    Under a timeline, therefore the salient point is "quickly" and willing to throw some $ at it too (doesn't have to be a free solution). Looking for an RSS feed generator usuable in .NET framework 2.0. Ideally it would be easy to use (inferred quick) but flexible enough to support the multiple standards (shown part way down this page). We have the business classes in .NET and want to publish RSS feeds on the ASP.NET website. Any software that's good? Doesn't have to be free. Must support .NET framework 2.0 Thanks.

  • Composite Views and View Controllers

    - by BillyK
    Hi, I'm somewhat new to Android and am in the process of designing an application with a couple fairly complex views. One of the views is intended to involve a complex view displaying information associated with model objects and segregated into several different views; the navigation of which is meant to be achieved using sliding effects (i.e. sliding one's finger across the screen to traverse from one screen to the next, etc). The view itself will be used to host multiple sets of views for varying types of model objects, but with a general structure that is reused between them all. As a rough example, the view might come up to display information about a person (the model object), displaying several details views: a view for general information, a view displaying a list of hobbies, and a view displaying a list of other individuals associated with their social network. The same general view, when given a model object representing a particular car would give several different views: A general view with details, A view containing photo images for that vehicle, a view representing locations which it could be purchased from, and a view providing a list of related cars. (NOTE: This is not the real data involved, but is representative of the general intent for the view). The subviews will NOT cover the entire screen real-estate and other features within the view should be both visible and able to be interacted with by the user. The idea here is that there is a general view structure that is reusable and which will manage a set of subviews dynamically generated based upon the type of model object handed to the view. I'm trying to determine the appropriate way to leverage the Android framework in order to best achieve this without violating the integrity of the framework. Basically, I'm trying to determine how to componentize this larger view into reusable units (i.e. general view, model-specific sub-view controllers, and individual detail views). To be more specific, I'm trying to determine if this view is best designed as a composite of several custom View classes or a composite of several Activity classes. I've seen several examples of custom composite views, but they typically are used to compose simple views without complex controllers and without attention to the general Activity lifecycle (i.e. storing and retrieving data related to the model objects, as appropriate). On the other hand, the only real example I've seen regarding a view comprised of a composite of Activities is the TabActivity itself, and that isn't customizable in the fashion that would be necessary for this. Does anyone have any suggestions as to the appropriate way to structure my view to achieve the application framework I'm looking for? Views? Activities? Something else? Any guidance would be appreciated. Thanks in advance.

  • How to solve the performance decay of a VB.NET 1.1 application?

    - by marco.ragogna
    I have single-thread windows form application written with VB.NET and targeting Framework 1.1. The software communicates with external boards through a serial interface, and it mainly consist of a state machine that run some tests, driven in a loop done with a Timer and an Interval of 50ms. The feedback on the user interface is done through some custom events raised during the tests. The problem that is driving me crazy is that the performance slightly decrease over time, and in particular after 1200/1300 test operations. The memory occupied does not increase over time, it is only the CPU that seems interested by this problem. The strange thing is that, targeting framework 2.0 and using the same identical code, I do not have this problem. I know that is difficult without looking at the code, but do you have suggestions how can I approach the problem?

  • Using jquery with nested masterpages

    - by diver-d
    Hi everyone, Can anyone show me how to use jquery in an asp.net nested masterpage. I have my main masterpage where I have added the link to the jquery libaray and also the validation framework. I have then created another masterpage with some styling and created a aspx page based on that masterpage. How can I attach the validation framework to textboxes within my page? I have tried $("#aspnetForm").validate({ rules: { <%=txtPostCode.UniqueID %>: { minlength: 2, required: true }, <%=txtContactEmail.UniqueID %>: { required: true, email:true } }, messages: { <%=txtPostCode.UniqueID %>:{ required: "* Required Field *", minlength: "* Please enter atleast 2 characters *" } } }); However nothing happens. Can anyone point me in the right direction?

  • logging in scala

    - by IttayD
    In Java, the standard idiom for logging is to create a static variable for a logger object and use that in the various methods. In Scala, it looks like the idiom is to create a Logging trait with a logger member and mixin the trait in concrete classes. This means that each time an object is created it calls the logging framework to get a logger and also the object is bigger due to the additional reference. Is there an alternative that allows the ease of use of "with Logging" while still using a per-class logger instance? EDIT: My question is not about how one can write a logging framework in Scala, but rather how to use an existing one (log4j) without incurring an overhead of performance (getting a reference for each instance) or code complexity. Also, yes, I want to use log4j, simply because I'll use 3rd party libraries written in Java that are likely to use log4j.
