  • Template approach for a PHP application

    - by Industrial
    Hi everyone, We're in the middle of making a new e-commerce related PHP application and we have come to the point where we have started to think about how we should solve templating for our customers needs. What we would like to do is offer our customers the possibility of uploading/modifying templates to suit their company:s profile. The initial thought is that we shall not reinvent the wheel, so instead letting our customers upload their templates with FTP, so there will be basic HTML skills required. For those customers that want to modify/customize template and doesnt have the knowledge, we offer that service as well. I know that there's a number of issues to solve before this could be considered safe, like preventing XSS and writing scripts that check through each uploaded file for potential security threats and so on. Of course, there are some part that probably will be to complex for the customer to modify by themselves, so maybe this approach won't apply to all<< template files in the frontend application. But besides that, what would be a good way to handle this?

  • Does GAE/OpenID/OAuth support xmlhttp proxy?

    - by h2g2java
    Currently, my code would construct the GWT form, which user would submit directly to openId (or any authenticaiton service). Such a method works fine. However, what if I had the gwt page server access the OpenID provider, is there a way/strategy for the server to mediate authentication between its client and the auth provider? I wish to know the answers with respect to GAE as the proxy and, regardless if GAE or Tomcat is the intended proxy, answers wrt Google Accounts OpenID OAuth If so, it would be wonderful if someone could describe the installation strategy.

  • Joomla , forms with upload and custom field from inside the administration panel

    - by Stathis
    I want a plugin for joomla like jforms or chronoforms in order to make a form to upload videos along with other custom fields to db and manage them. The only problem is I want this functionality to be made from inside the administrator console and not to appear on a page at my site's frontend. My site does not have a login service , so I need to make the admin able to login to administration panel and from there to upload and manage videos. Do you know of a plugin wich supports this functionality? Thank you in advance.

  • What is an Enterprise Java Bean really?

    - by HDave
    On the Tomcat FAQ it says: "Tomcat is not an EJB server. Tomcat is not a full J2EE server." But if I: use Spring to supply an application context annotate my entities with JPA annotations (and use Hibernate as a JPA provider) configure C3P0 as a connection pooling data source annotate my service methods with @Transactional (and use Atomikos as JTA provider) Use JAXB for marshalling and unmarshalling and possibly add my own JNDI capability then don't I effectively have a JEE application server? And then aren't my beans EJBs? Or is there some other defining characteristic? What is it that a JEE compliant app server gives you that you can't easily/readily get from Tomcat with some 3rd party subsystems?

  • Returning a users lat lng as a string iPhone

    - by Joshmattvander
    Is there a way to return the users location as a string from a model? I have a model thats job is to download same JSON data from a web service.

But I cant find out how to explicitly return the lat and lng values. Im only 2 days into iPhone dev so go easy on me :)

  • Setting up Android application for Analytics and tracking

    - by Samuh
    Tracking events and setting up Analytics for Websites seems easy. You create an account with one of the Analytics service providers like Google. They give you javascript code that you embed in your pages (whichever event you wish to track) and voila..you're done. I have written a native application for Android phones, which is actually an adaptation of the actual web site. Now, I am required to setup Analytics and tracking for this native application. Question: How to do setup a native application for Analytics? We have Java Script code(not Google Analytics but for some other engine) that works for the original web site. Is there a way to incorporate that in the native application? I know Android supports Java Script via WebViews(Webkit);my application does not have webviews, it is native! I have not worked on JavaScript since school so excuse me if I sound naive. Thanks.

  • PAC with kerberoes

    - by Varun
    I am currently working on kerberoes, and for now have this doubt on PAC in MS-KILE kerberoes extension. Can pac included in pactype strcuture withtin authorization data, is meant for client to decrypt and decode. It seems (if my understanding is correct), that PAC is encrypted with target server's encryption key, which is known only to kdc and target server, and therefore, client just needs to forward that to server when requesting a service, and isn't suppose to decrypt and extract details about its credentails. Is there a way to try to decrypt this on the fly? ( is there sufficient information available in AS-REP for me extract and decrypt this?

  • Entity Framework - Self Tracking Objects - how to reset client side?

    - by David
    I am using wcf with self tracking entity framework objects. On the client side i have bound an entity to an edit form (which has multiple textboxes and comboboxes). After the user hits Save, the entity is sent through wcf to the server wcf service which will attempt to save the entity. If there is a failure (say a network failure), I need to reset the current entity back to original values. How best can I do this client side? (I recognize with Self Tracking objects there is a property OriginalValues however that collection seems to have count=0) so not sure how to get the original values? Thanks-

  • How to find/display the Upload File limits on IIS with ASP.NET?

    - by NVRAM
    I have a web service on which the end users will be uploading ZIP archives that can be very large (one test file is over 200MB). I'd like to handle oversized files proactively and size-limited upload failures gracefully. Since the web app will be deployed on customers' machines, so I cannot easily ensure that the configuration matches any fixed size. I've documented how to use the appcmd command for them to set the requestLimits.maxAllowedContentLength value beyond the 30MB default. But I'd like to handle it in the web app; I'm hoping for two things: To show the current limit on the page where they initiate the file upload, something along the lines of: Each file upload is limited to 15MB. If your archive is larger, (etc., etc., etc.) To give a meaningful error when that size is exceeded. Currently, it takes a long time for the data to be sent, and then I see a misleading 404 page. Any thoughts?

  • .NET platform independant sync framework

    - by Quandary
    Question: I need to synchronize a few ActionScript files from my computer to a network share (backup). I saw a quick fix would be using Microsoft Sync Framework for this, and write a windows service. My problem is I also use Linux, and before I start with MS vendor lockin, is there any sync framework/library/whatever I could use that works accross platform? Or does the MS sync framework work on Linux, too? It is my understanding that it is a wrapper around some com objects, thus it wouldn't work. All I need is synchronizing files. So never mind the database part, although it would be nice to have it, too.

  • [C#] Running elevated applications on user login with UAC?

    - by Alex
    I need to start a program every time the user logs in, but I cannot do this without being met by a UAC dialog asking for permissions for that application. Is there any way to have an application start up on user login without the user having to answer the UAC prompt? I was thinking about running a service, but this would be a last resort. I saw something about an Application Compatibility Toolkit to disable UAC for certain applications, but I feel this is too big of a hassle - even services would be easier to program. I was just wondering if there is an even easier solution I am missing. Thanks in advance.

  • WCF interoperability with WSDL proxy and performance consideration advise.

    - by user194917
    I'm essentially writing a broker service. The requirement is that I write an API that acts as an intermediary broker between our in-house developed services and a 3rd party provided API. The intention being that my API abstract the actual communication with the 3rd party API from our internal systems. The architect on the project chose WCF as the communication framework. The problem is that 70 percent of our subscriber applications are written in .Net 2 and as such have no access to the class libraries required to implement a WCF proxy. The end result being that our proxy classes are loosely based on the code auto generated by the WSDL tool as opposed to the SvcUtil tool. My question is, although I have no issues implementing the required proxy classes using basicHttp as the actual binding and using the WSDL tool, are there any special considerations that I need to take into account in this scenario? I.E proxy optimizations and the like. Thanks in advance.

  • InfoPath Getting SharePoint Group Information

    - by anon
    I have an InfoPath form embedded in an aspx page on a SharePoint site. How do I bind the SharePoint user groups to a drop-down list on my form? What I've tried so far is to create a data connection to a web service (method GetGroupCollectionFromWeb) to pull the data. Next, I open the list box properties, select "Look up values from an external data source", select the data source, assign the entries, and I get the following error: "You must select a repeating group or field." What I don't understand is that since the method I am calling is called GetGroupCollectionFromWeb, isn't the return value a collection? And aren't collections repeating by definition? What am I missing, and is there a workaround? Thank you.

  • Firefox extension dev: observing preferencies, avoid multiple notifications

    - by Michael
    Let's say my Firefox extension has multiple preferences, but some of them are grouped, like check interval, fail retry interval, destination url. Those are used in just single function. When I subscribe to preference service and add observer, the observe callback will be called for each changed preference, so if by chance user changed all of the settings in group, then I will have to do the same routine for the same subsystem as many times as I have items in that preferences group. What I want is observe to be called just once for group of preferences. Say extensions.myextension.interval1 extensions.myextension.site extensions.myextension.retry so if one or all of those preferences are changed, I receive only 1 notification about it.

  • Crowdsourcing translation for mobile developers?

    - by superg
    I am developing applications for mobile phones with different operating systems (Android, Symbian, iPhone). Applications are sold internationally so they need to be translated to different languages in addition to english version. I assume most mobile developers do the translations using some paid external service each time. This approach does not look very cost-effective to me. Would it make sense to have a website where simple translations would be done using crowdsourcing (other developers)? Most strings in mobile applications are very simple and short, for example "OK, "Cancel", "Are you sure?", "Please enter your password". Also the same strings are used in hundreds of applications. Instead of paying for translating all strings, developers could save money by only buying their difficult application specific translations. Does anyone agree with this idea? I have seen many opensource projects doing the translations succesfully using volunteers.

  • First-time contractor question: how do I handle web hosting?

    - by abeger
    I've started doing a little freelance web work and I've got to build a site for a client. The client doesn't currently have a hosting service, so either I or they are going to have to set it up. Traditionally, how does this work out? Do I set it up and then transfer ownership to them when I'm done? Do I leave it to them to set it up? If they're going to be paying for the hosting directly, does that affect anything? Basically, I'm brand new at all this and any and all advice on how to handle hosting would be greatly appreciated.

  • Querying my JPA provider (Hibernate) for a collection of <Id,Name> of an entity

    - by Ittai
    Hi, I have an entity which looks something like this: Id (PK) Name Other business properties and associations... I have the need for my DAL (JPA with hibernate as provider) to return a list of the entities which correlate to some constraints (or just return them all) but instead of returning the entities themselves I'd like to receive only the Id and the Name properties. I know this can be achieved with HQL/SQL (something like: select id,name from entity where...) but I don't want to go down that road. I was thinking of somehow defining the pair a compositioned part of the entity and thought that might help me but I'm not sure that's "legal" as the Id is the PK. The logic for this scenario is to have a textbox which asynchronously queries the web-service (and through it the DAL) for the relevant entities and once an entity is selected then it is loaded as a whole and shipped to the front-end. Would appreciate any feedback, Ittai

  • WebService Security

    - by LauzPT
    Hello, I'm developing an project, which consists in a webservice and a client application. It's a fair simple scenario. The webservice is connected to a database server, and the client consumes from the webserver in order to get information retrieved from the database. The thing is: 1. The client application can only display data after a previous authentication; 2. All the data transferred between Web Service and clients must be confidential; 3. Data integrity shouldn’t be compromised; I'm wondering what is the best way to achieve these requirements. The first thing I thought about, was sending the server a digital signature containing a client certificate, to be stored in the server, and used as comparison for authentication. But I investigated a little about webservice security, and I'm no longer certain that this is the best option. Can anyone give me an opinion about this? TIA

  • Preventing dictionary attacks on a web application

    - by Kevin Pang
    What's the best way to prevent a dictionary attack? I've thought up several implementations but they all seem to have some flaw in them: Lock out a user after X failed login attempts. Problem: easy to turn into a denial of service attack, locking out many users in a short amount of time. Incrementally increase response time per failed login attempt on a username. Problem: dictionary attacks might use the same password but different usernames. Incrementally increase response time per failed login attempt from an IP address. Problem: easy to get around by spoofing IP address. Incrementally increase response time per failed login attempt within a session. Problem: easy to get around by creating a dictionary attack that fires up a new session on each attempt.

  • Login implementation for windows mobile

    - by pdiddy
    What is a good approach for credential checks for windows mobile app. Knowing that it is an occasionally connected device. Should I keep the user credential into the local database? If the credential doesn't exist in the db, try to see if it has internet access and do the check through a web service? If both fails then display an error message ? If logins is successful then store the credential to the local database store then upon next login go against the database first? Is this a good approach?

    Well i am a bit confused.. I saw a service known as Zopim..

Can any body let me know how this works and from where i can learn this.. + how can they even set the CSS with this and also the looks? Awaiting for your replies... Thanks

  • Creating hashmap/map from XML resources

    - by KimAMartinsen
    Hi! I'm making an application where a web service fetches (amongst other) a bunch of codes from a webservice (I.e BEL, FRA, SWE). During runtime I want to translate these codes to their apporiate names to display to users (I.e Belgium, France, Sweden). There can be a lot of these codes, so i'm wondering if there is any approriate way to store the (code, name) entry as a some sort of map in the XML resources in Android, so I can quickly fetch the name by the given code? It's all about speed here, since the map can have a few hundred entries.

  • What is your prefered way to return XML from an ActionMethod in Asp.net MVC?

    - by serbrech
    I am displaying charts that load the data asynchronously because the searches are the work to fetch the data is quite heavy. The data has to be return as XML to make the chart library happy. My ActionMethods return a ContentResult with the type set as text/xml. I build my Xml using Linq to XML and call ToString. This works fine but it's not ideal to test. I have another idea to achieve this which would be to return a view that builds my XML using the XSLT View engine. I am curious and I always try to do the things "the right way". So how are you guys handling such scenarios? Do you implement a different ViewEngine (like xslt) to build your XML or do you Build your XML inside your controller (Or the service that serves your controller)?

  • Can't establish a DB connection. (Maybe threads related)

    - by JobGovernor
    Hello, I am getting this exception on the Rufus::Scheduler ActiveRecord::ConnectionTimeoutError: could not obtain a database connection within 5 seconds. The max pool size is currently 30; consider increasing it. I've increased the pool from 10 to 30. And I also monkey patched the method which raises the exception to also call ActiveRecord::Base.verify_active_connections! before doing its job. And I also restarted the service which executes the script so that the new code is run. Any ideas would be greatly appreciated. Let me know if you need any other info about environment or whatnot. Thank you.
