  • Accessing Remote ASP.NET Web Services' JSON data

    - by Emon
    How can I best create a webservice method which returns JSON data that is to be consumed by an application on a different domain? The following article talks about how to set it up: http://www.codeproject.com/KB/webservices/ASPNET_JSONP.aspx I havent tried it out yet but it seems like there are a lot of steps and the ajax client has to do some extra work. My question, is there a better way to do this? Also, I dont know too much about WCF services. Would I still have to go through a lot of work to enable JSONP? Thanks in advance.

  • How do I design a web service (microsoft) that can be consumed by multiple end points?

    - by Ben McCormack
    My company is planning to implement a solution in multiple applications that will help to validate mailing addresses at the point of data entry. We're using UPS's Extended Address Validation (XAV) web service API to validate the addresses. Our current plan is to build a .NET web service that can be used to communicate between our applications and the UPS API. We have applications in VB6, classic ASP, and .NET 2.0, so we'd like to implement a solution that can be easily consumed by each of these programming environments. What are our (Microsoft) options for designing a web service that can be consumed by multiple clients? In particular, is there a way to design a single web service that can respond with JSON (in case we want to validate our web page using javascript) in addition to XML? I'm new to designing web services and want to make sure we consider all of our options. I've heard terms like asmx, WCF, OData, etc., but I don't know which frameworks will support what we're trying to do and where to start.

  • How do I stop a page from unloading (navigating away) in JS?

    - by Natalie Downe
    Does anyone know how to stop a page from reloading or navigating away? jQuery(function($) { /* global on unload notification */ warning = true; if(warning) { $(window).bind("unload", function() { if (confirm("Do you want to leave this page") == true) { //they pressed OK alert('ok'); } else { // they pressed Cancel alert('cancel'); return false; } }); } }); I am working on an e-commerce site at the moment, the page that displays your future orders has the ability to alter the quantities of items ordered using +/- buttons. Changing the quantities this way this doesn't actually change the order itself, they have to press confirm and therefore committing a positive action to change the order. However if they have changed the quantities and navigate away from the page I would like to warn them they are doing so in case this is an accident, as the changed quantities will be lost if they navigate away or refresh the page. In the code above I am using a global variable which will be false by default (its only true for testing), when a quantity is changed I will update this variable to be true, and when they confirm the changes I will set it to false. If warning is true and the page is unloaded, I offer them a confirmation box, if they say no they would like to stay on this page I need to stop it from unloading. return false isn't working, it still lets the user navigate away (the alerts are there for debugging only) Any ideas?

  • Java Client interoperating with WSE 3.0 Web Service

    - by Dee
    I have a Interoperable Security Token Service (STS) that authenticates the User and then issues a SAML token. I also have transaction services that expects the SAML token in the incoming SOAP request header. For a client to make a call to transaction service, it first needs to authenticate with the STS, get the SAML token and then make a call to the transaction services. The STS is an interoperable service and can be invoked from a Java client. The Transaction services are build using WSE 3.0 framework, but the WSDL that it generates is not good enough for a Java client to understand it. I want my Java client to explicitly call the STS and then using the received SAML token make a call to Transaction Services. I tried with Netbeans and Metro WSIT toolkit. I was able to call the Transaction Services if it were implemented using WCF. With WCF Transaction Service the WSDL generated has complete information using which the Java client can figure out how to call to STS and then call the WCF Transaction service. How can my Java client explicitly call the STS and then in turn call the WSE 3.0 transaction services?

  • Best Practices for a Web App Staging Server (on a budget)

    - by fig-gnuton
    I'd like to set up a staging server for a Rails app. I use git & github, Cap, and have a VPS with Apache/Passenger. I'm curious as to the best practices for a staging setup, as far as both the configuration of the staging server as well as the processes for interacting with it. I do know it should be as identical to the production server as possible, but restricting public access to it will limit that, so tips on securing it only for my use would also be great. Another specific question would be whether I could just create a virtual host on the VPS, so that the staging server could reside alongside the production one. I have a feeling there may be reasons to avoid this, though.

  • How do I use jQuery for click event in iPhone web application

    - by Gazzer
    When I use jQuery for a simple click event it only works for links. Is there a way to make it work for spans etc: $("span.clicked").live("click", function(e){alert("span clicked!")}); $("a.clicked").live("click", function(e){alert("link clicked!")}); Example is here: http://ip1n.j-www.com/test/index2.html The SPAN works in Safari but not Mobile Safari (on iPhone or iPad) whereas the A tag works in both.

  • Web Service returning object with null fields

    - by Xaiter
    Never seen this one before. WebService.Implementation imp = new WebService.Implementation(); WebService.ImplementationRequest req = new WebService.ImplementationRequest(); return imp.GetValue(req); The object that imp returns is not null. It's returning an ImplementationResponse, as expected. But all of the fields in that object are null. Which is not expected. The WebService, currently, just returns some constant dummy data. We've tested this on another developer's machine, works just fine. I suppose I should also note that the WebService should throw an exception if I pass null into the GetValue method. It doesn't. Not for me. Any idea what could be wrong with my environment that could make a WebService return an object, but make every value in that object null? And somehow 'magically' return this mystery object when it should be throwing an exception?

  • Cheapest ways to expose internet services

    - by tmow
    Hi all, we have developed/customized an internet site that provides functionalities like sharing, swap/barter, selling and rent any object/services trough public or private galleries and/or clubs. We'd like now to expose all or some of the services to the public, so that anybody can take advantage of our engine, but without spending too much as we rae running low on budget. At the moment we have developed some RSS interfaces for the public catalogs and is possible to use JQuery to query the engine. Do you have any advices on how to proceed here? We were thinking about something simple like framset, using openID like authentication, or similar technologies. Even if can be the coolest solution, we a would like to avoid the develop soap, rest or xmlrpc APIs as it takes a lot of time ( =money ) Do you have any super smart ideas?

  • Freelance web hosting - what are good LAMP choices?

    - by tkotitan
    I think it's best if I ask this question with an example scenario. Let's say your mom-and-pop local hardware store has never had a website, and they want you, the freelance developer to build them a website. You have all the skills to run a LAMP setup and admin a system, so the difficult question you ask yourself is - where will I host it? As you aren't going to host it out of the machine in your apartment. Let's say you want to be able to customize your own system, install the version of PHP you want, and manage your own database. Perhaps the best kind of hosting is to get a virtual machine so you can customize the system as you see fit. But this essentially a "set it and forget it" site you make, bill by the hour for, and then are done. In other words, the hosting should not be an issue. Given the requirements of hosting a website: Unlimited growth potential needing good amounts of bandwidth to handle visitors Wide range of system and programming options allowing it to be portable Relatively cheap (not necessarily the cheapest) or reasonable scaling cost Reliable hosting with good support Hosted entirely on the host company's hardware Who would you pick to host this website? Yes I am asking for a business/company recommendation. Is there a clear answer for this scenario, or a good source that can reliably give the current answer? I know there are all kinds of schemes out there. I'm just wondering if any one company fills the bill for freelancers and stands out in such a crowded market.

  • Browser Preview Utility

    - by just_wes
    Hello everybody, Are there any programs that render websites from the point of view of different browsers? In other words, I'd like to be able to open and view websites as if it were Internet Explorer, Firefox, Chrome, Safari, etc. It would be a bonus if the utility has a paned interface that lets you view pages side by side. Thanks!

  • CSS content overflowing containing div

    - by kaese
    Hi, Currently have a problem with some DIVs overlapping their containing DIVs. See image below (the 3 products at the bottom): All the body content of the page is held within the #content DIV: div#content { width: 960px; float: left; background-image: url("../img/contentBg.png"); background-repeat: repeat; margin-top: 10px; line-height: 1.8em; border-top: 8px solid #5E88A2; padding: 10px 15px 10px 15px; } And here is the CSS for the product boxes within the #content div: .upper { text-transform: uppercase; } .center { text-align: center; } div#products { float: left; width: 100%; margin-bottom: 25px; } div.productContainer { float: left; width: 265px; font-size: 1em; margin-left: 50px; height: 200px; padding-top: 25px; text-align: right; } div.product { float: left; width: 200px; } div.product p { } div.product a { display: block; } div.product img { float: left; } div.product img:hover { opacity: 0.8; filter: alpha(opacity = 80); } div.transparent { opacity: 0.8; filter: alpha(opacity = 80); } And here is the HTML for the boxes: <div class="productContainer"> <div class="product"> <h2 class="upper center">A2 Print</h2> <a href='../edit/?productId=5&amp;align=v' class='upper'> <img src="../../wflow/tmp/133703b808c91b8ec7e7c7cdf19320b7A2-Print.png" alt="Representation of image printed at A2 Print through MyPersonalPoster." /></a> <p class="upper">16.5 inches x 23.4 inches<br /><strong>&pound;15.99</strong></p> <p class="upper smaller"><em><span><span class="yes">Yes</span> - your picture quality is high enough for this size</span> </em></p> <p><a href='../edit/?productId=5&amp;align=v' class='upper'><span>Select</span></a></p> </div> </div> <div class="productContainer"> <div class="product transparent"> <h2 class="upper center">A1 Print</h2> <a href='../edit/?productId=11&amp;align=v' class='upper'> <img src="../../wflow/tmp/133703b808c91b8ec7e7c7cdf19320b7A1-Print.png" alt="Representation of image printed at A1 Print through MyPersonalPoster." /></a> <p class="upper">23.4 inches x 33.1 inches<br /><strong>&pound;19.99</strong></p> <p class="upper smaller"><em><span><span class="no">Warning</span> - your picture quality may not be sufficient for this size</span> </em></p> <p><a href='../edit/?productId=11&amp;align=v' class='upper'><span>Select</span></a></p> </div> </div> <div class="productContainer"> <div class="product transparent"> <h2 class="upper center">Poster Print (60cm x 80cm)</h2> <a href='../edit/?productId=12&amp;align=v' class='upper'> <img src="../../wflow/tmp/133703b808c91b8ec7e7c7cdf19320b7Poster-Print-(60cm-x-80cm).png" alt="Representation of image printed at Poster Print (60cm x 80cm) through MyPersonalPoster." /></a> <p class="upper">23.6 inches x 31.5 inches<br /><strong>&pound;13.95</strong></p> <p class="upper smaller"><em><span><span class="no">Warning</span> - your picture quality may not be sufficient for this size</span> </em></p> <p><a href='../edit/?productId=12&amp;align=v' class='upper'><span>Select</span></a></p> </div> </div> Any idea what could be causing these DIVs to overlap? What I'd like is for all the boxes to fit within the #container div as expected. It's driving me crazy! Cheers

  • Transporting servers - need special rack/case

    - by Nso
    I am responsible for our companys server infrastructure at trade shows. We have 2 annual shows, 1 in Las Vegas and 1 in Amsterdam, so obviously our servers do quite a bit of travelling. Quite often, it gets home with pieces falling off, and insurance/rebuilding takes ages and cost a lot of money. For now I have been using a wooden rack-box, with steel-reinforced sides/corners, but I am looking for something tougher. Does anyone have experience with sending servers all around the world, without them dieing all the time?

  • Question about finding third party website APIs.

    - by Abe Miessler
    I have a client that works with several well established 3rd party sites to sell his product (in this case hotel rooms, but the question is more general). Every time he gets a reservation he has to go to each site and manually make changes. I've done a quick search to see if there are APIs or any developer resources for these sites but have come up with nothing. I've emailed his contacts for each site but have yet to receive a response. I don't have a lot of experience working with third party sites like this but in the past when I've looked for APIs I usually come up empty handed. Are these types of APIs rare or am I just looking in the wrong places? It seems like an obvious thing to have for a company that has an affiliate program. Any suggestions on where to look for APIs or am I at the mercy of my "contact"?

  • Drawing rectangles on a grid in a web browser

    - by Dhruv
    I would like to create an online, simple WYSIWYG drawing editor allowing people to draw rectangular shapes. I'm thinking of a grid which the lines and points can snap on to, ensuring that the lines are strictly vertical or horizontal. I will be parsing the rectangular shapes to obtain some area calculations and compute certain things. How can I achieve the drawing ability? The new canvas tag is good but people have been telling me that IE does not support it. I found some Java applets but I have never programmed in Java before. Is there a way to do this using pure javascript or jquery? Does ASP.NET help at all? Thanks.

  • Changing color of a row in dropdown list

    - by Judy
    is it possible to change "selector" color in drop-down list? <select name="select" style="background-color: #ff0000"> <option style="background-color: #ff0000" value="1">Red</option> <option style="background-color: #ffffff" value="2">Green</option> <option style="background-color: #0000ff" value="3">Blue</option> </select> I tried in above style but it didn't worked. I know with javascript getting document.getElementById('text').style.color='red' can set the color. But is it possible in html to set the colors?

  • Scheduling jobs from a web environment on Linux

    - by Anders Feder
    Hi. I am developing an application in PHP on Linux/Apache. I want to be able to schedule PHP jobs (scripts) for execution at some specific time in the future from within the application. I know that many people will recommend cron and at, but first of all I don't need recurrence (cron) and secondly and most importantly, I need the solution to be able to scale. At was not designed with race condititions in mind, and if two users try to add a job at the same time one or both may fail. It's also important that jobs are executed at their specified time, and not just 'polled' once per minute or so. Can anyone please suggest solutions for this task? Thank you.

  • Deserialising Json to derived types in Asp.Net Web API

    - by IoChaos
    I'm calling a method of my WebAPI sending a json that I would like to match (or bind) with a model. In the controller I have a method like: public Result Post([ModelBinder(typeof(CustomModelBinder))]MyClass model); 'MyClass', wich is given as a parameter is an abstract class. I would like that at, depending of the type of json passed, the correct inherited class is instantiated. To achieve it, I'm trying to implement a custom binder. The problem is that (I don't know if it's very basic but I can't find anything) I don't know how to retrieve the raw Json (or better, some kind of serialization) that comes in the request. I see: actionContext.Request.Content But all methods are exposed as async. I don't know who this fits with passing the generate model to the controller method... Thanks a lot!
