  • WCF Web/ServiceHost - Singletons and initialisation

    - by Kyle
    I have some Service class which is defined as InstanceContextMode.Single, and is well known in the hosting application. (The host creates an instance, and passes that to the WebServiceHost) Hosting app:WebServiceHost host = null; SomeService serviceInstance = new SomeService("text", "more text"); host = new WebServiceHost(serviceInstance, baseUri); Problem: When I go to use the variables initialised when the service is created (ie, when a call is made to the service), they are either null or empty... Am I wrong in assuming that as the instance being initialised in the hosting application is used for each request to the WebServiceHost? Any pointers here would be great.

  • How can one extract rdf:about or rdf:ID properties from triples using SPARKQL?

    - by lennyks
    It seemed a trivial matter at the beginning but so far I had not managed to get unique identifier for a given resource using SPARKQL. What I mean is given, let say, rdf:Description rdf:about="http://..." and then some properties identifying this resource, what I want to do is to first find this very resource and then retrieve all the triples given some uri. I have tried naive approaches by writing statements in a WHERE clause such as ?x rdf:about ?y and ?x rdfs:about ?y. I hope I am being precise.

  • Programmatically access currency exchange rates

    - by Adam Pierce
    I'm setting up an online ordering system but I'm in Australia and for international customers I'd like to show prices in US dollars or Euros so they don't have to make the mental effort to convert from Australian dollars. Does anyone know if I can pull up to date exchange rates off the net somewhere in an easy-to-parse format I can access from my PHP script ? UPDATE: I have now written a PHP class which implements this. You can get the code from my website.

  • How to output multicolumn html without "widows"?

    - by user314850
    I need to output to HTML a list of categorized links in exactly three columns of text. They must be displayed similar to columns in a newspaper or magazine. So, for example, if there are 20 lines total the first and second columns would contain 7 lines and the last column would contain 6. The list must be dynamic; it will be regularly changed. The tricky part is that the links are categorized with a title and this title cannot be a "widow". If you have a page layout background you'll know that this means the titles cannot be displayed at the bottom of the column -- they must have at least one link underneath them, otherwise they should bump to the next column (I know, technically it should be two lines if I were actually doing page layout, but in this case one is acceptable). I'm having a difficult time figuring out how to get this done. Here's an example of what I mean: Shopping Link 3 Link1 Link 1 Link 4 Link2 Link 2 Link 3 Link 3 Cars Link 1 Music Games Link 2 Link 1 Link 1 Link 2 News As you can see, the "News" title is at the bottom of the middle column, and so is a "widow". This is unacceptable. I could bump it to the next column, but that would create an unnecessarily large amount of white space at the bottom of the second column. What needs to happen instead is that the entire list needs to be re-balanced. I'm wondering if anyone has any tips for how to accomplish this, or perhaps source code or a plug in. Python is preferable, but any language is fine. I'm just trying to get the general concept down.

  • Copying only the changed files while mirroring a website

    - by Rishi Verma
    I am using wget to mirror website using this code $ wget \ --recursive \ --no-clobber \ --page-requisites \ --html-extension \ --convert-links \ --restrict-file-names=windows \ --domains website.org \ --no-parent \ www.website.org/tutorials/html/ The next time I run it it starts downloading the same files again, however I want only the changed files to be downloaded next time. I am open to use any other tool or script(preferably PHP,Curl) apart from using wget.

  • Using IAM for user authentication

    - by mdavis6890
    I've read lots and lots of posts that touch on what I think should be a very common use case - but without finding exactly what I want, or a simple reason why it can't be done. I have some files on S3. I want to be able to grant certain users access to certain files, via a front end that I build. So far, I've made it work this way: I built the front end in Django, using it's built-in Users and Groups I have a model for Buckets, in which I mirror my S3 buckets. I have a m2m relationship from groups to buckets representing the S3 permissions. The user logs in and authenticates against Django's users. I grab from Django the list of buckets that the user is allowed to see I use boto to grab a list of links to files from those buckets and display to user. This works, but isn't ideal, and also just doesn't feel right. I've got to keep a mirror of the buckets, and I also have to maintain my own list of user/passwords and permissions, when AWS already has all that built in. What I really want is to simply create the users in IAM and use group permissions in IAM to control access to the S3 buckets. No duplication of data or function. My app would request a UN/PW from the user and use that to connect to IAM/S3 to pull the list of buckets and files, then display links to the user. Simple. How can I, or why can't I? Am I looking at this the wrong way? What's the "right" way to address this (I assume) very common use case?

  • How to enforce a namespace in wsdl for inner elements

I am just using this as an example as the element that are children of soapenv always have a namespace prefix, however, the children of these children do not have any prefix. This is the case with soapUI and message sent by Axis2 generated stubs. My questions are: 1. Why aren't there any namespace for arg0? 2. Is there a way to enforce myp prefix on arg0 from WSDL? If so, how? If not, why can't it be done?

  • RoR app running on mongrel development but not production

    - by ANaimi
    Hello all, This is my first stab at Ruby on Rails. Just deployed a very simple app to Heroku. The thing is that my app runs flawlessly on mongrel development; When I run it with "mongrel_rails start -e production" however, I get the error "We're sorry, but something went wrong." For the life of me, I couldn't debug this. Heroku logs is not returning anything, the Exceptional addon in Heroku is not returning anything, and I cannot find mongrel.log on my Windows machine (when I run mongrel using: mongrel_rails start -e production -d" I'm using Rails 2.3.5 and sqlite3 with bundler to pack my gems. I was told that probably rails is not booting up correctly. I can't find any other way to diagnose this. Any ideas? Thanks, ANaimi

  • I would like to interactively detect when an ActiveX component has been installed, and asynchronousl

    - by Brian Stinar
    Hello, I am working on a website, and I would like to refresh a portion of the page after an ActiveX component has been installed. I have a general idea of how to do this with polling, which I am working on getting going : function detectComponentThenSleep(){ try{ // Call what I want ActiveX for, if the method is available, or // ActiveXComponent.object == null --- test for existance document.getElementById("ActiveXComponent").someMethod(); } catch{ // Try again, if the method is not available setTimeout(detectComponentThenSleep, 100); } } However, what I would REALLY like to do is something like this: ActiveXObject.addListener("onInstall", myfunction); I don't actually have the source for the ActiveX component, but I have complete control of the page I am hosting it on. I would like to use JavaScript, if possible, to accomplish this. So, my question is 1.) will this actually work with the polling method? and 2.) Is there an interrupt/listener like way of doing this? I am sure I am missing something with connecting the dots here, I can already detect if the component is present, but I am having trouble doing this asynchronously. Thank you very much for your time and help, -Brian J. Stinar-

  • Web-based code interpreter

    - by detly
    I remember coming across a website where I could type in some code and it would compile and run it (or error out), displaying any console output. It accepted a variety of interpreted and non-interpreted languages — I specifically remember that I could use C (maybe Python too... I'm not completely sure). Does anyone know what site I'm talking about?

  • Interoperability when returning derived class by base class in WCF

    - by mt_serg
    I have some simple code: [DataContract] [KnownType(typeof(SpecialEvent))] public class Event { //data } [DataContract] public class SpecialEvent : Event { //data } [ServiceContract] public interface IService { [OperationContract] List<Event> GetEvents(); } [ServiceBehavior] public class Service : IService { public List<Event> GetEvents() { List<Event> events = new List<Event>(); events.Add(new Event()); events.Add(new SpecialEvent()); return events; } } I know that it works fine in case wcf to wcf. but what about interoperability? is it generate standart wsdl and any client can use the service or no?

  • When to databind data-bound controls?

    - by sanjuro
    Hi, i have little dilemma, i often use data-bound controls such as Gridview in conjunction with ObjectDataSource. But i have two possible options when can i bind data to Gridview. The first is that i set datasourceid of gridview in aspx file and databind occurs in a moment before PreRender event occurs or i can set datasource in Page_Load event and databinding occurs immediately, something like this: protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { testGridView.DataSource = testObjectDataSource.Select(); testGridView.DataBind(); } } I think that in second approach i have more control above databinding. But how it is in real programming life? Which of the above two options is commonly used? Or is there some third option how can i bind data to data-bound control? Thanks for your opinions from real-life experiences.

  • AJAX in Rails - doing simple looping to update information when available

    - by Acidburn2k
    I am trying to get put out a simple site, which would pool the database every few seconds and update the information on the page dynamicly, when theres something new inserted. I am farily new to ruby, but I understand the whole concept of RJS, link_to_function and soforth. The question is, what is the best way how to implement some kind of simple loop, which would run after the page is loaded and update the DOM if there is something new to display. Thanks in advance for any tips!

  • What's the usual term for a local IIS/web application with services?

    - by JBRWilkinson
    I've inherited a multi-technology project which comprises a Flash user interface contained in a web-browser-like host and has an ASP.NET piece which provides web services to the Flash UI, background/watchdog services plus a web application for administration of the system. Our transatlantic project conference calls are getting confusing due to the various terms people use to describe the ASP.NET piece. Indeed, ASP.NET has its' own project terminology including 'Web Site' and 'Web Application' to both of which one can add a 'Web Service'. Is there any commonly-used name for this ASP.NET multi-purpose project piece?

  • PUT parameters not working in python / google app engine

    - by magegu
    hi, i'm working on a simple RESTful webservice with python with the webapp framework on the google app engine. Basically i'm sending all request via AJAX/jquery - for POST it works like a charm, but when I'm sending data with PUT, the parameters are empty / not processed. this is my PUT: $.ajax({ type: "PUT", url: "/boxes", data: { name: this.name, archived: this.archived }, success: function(msg){ } }); firebug saids i'm putting: Parameter application/x-www-form-urlencoded archived false name 123112323asdasd but using this python code: from google.appengine.ext import webapp from google.appengine.ext.webapp import util, template from google.appengine.ext import db from google.appengine.api.datastore_types import * from django.utils import simplejson as json import cgi import datetime class BoxHandler(webapp.RequestHandler): def post(self): #working print "test" self.response.out.write(self.request.get("name")) def put(self): print "test" #not working self.response.out.write(self.request.get("name")) will just return test Status: 200 OK Content-Type: text/html; charset=utf-8 Cache-Control: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Content-Length: 0 so .. hm, is there anything i'm missing here? cheers, Martin

  • Folders-like URL with PHP?

    - by Maxime
    Hi, ever since I added this htaccess to my website, I noticed a HUGE slowdown, and my error logs are filled with errors such as PHP Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in page.php on line 79. I've got up to four of these per second. Most of the time it works though. The htaccess consisted of two similar rules: one with two GET vars, another one with only one. RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)\/(.*)$ index.php?var1=$1&var2=$2 [L] Anyway, I just rewrote a PHP script that handles of all the strings and redirects where it should, and my website is now fast again. But is there a way to hide mypage.php?var1=la&var2=lu and still have URLs that look like folders? Thanks for your replies!

  • RESTful copy/move operations?

    - by ladenedge
    I am trying to design a RESTful filesystem-like service, and copy/move operations are causing me some trouble. First of all, uploading a new file is done using a PUT to the file's ultimate URL: PUT /folders/42/contents/<name> The question is, what if the new file already resides on the system under a different URL? Copy/move Idea 1: PUTs with custom headers. This is similar to S3's copy. A PUT that looks the same as the upload, but with a custom header: PUT /folders/42/contents/<name> X-custom-source: /files/5 This is nice because it's easy to change the file's name at copy/move time. However, S3 doesn't offer a move operation, perhaps because a move using this scheme won't be idempotent. Copy/move Idea 2: POST to parent folder. This is similar to the Google Docs copy. A POST to the destination folder with XML content describing the source file: POST /folders/42/contents ... <source>/files/5</source> <newName>foo</newName> I might be able to POST to the file's new URL to change its name..? Otherwise I'm stuck with specifying a new name in the XML content, which amplifies the RPCness of this idea. It's also not as consistent with the upload operation as idea 1. Ultimately I'm looking for something that's easy to use and understand, so in addition to criticism of the above, new ideas are certainly welcome!

  • Real time embeddable http server library required

    - by Howard May
    Having looked at several available http server libraries I have not yet found what I am looking for and am sure I can't be the first to have this set of requirements. I need a library which presents an API which is 'pipelined'. Pipelining is used to describe an HTTP feature where multiple HTTP requests can be sent across a TCP link at a time without waiting for a response. I want a similar feature on the library API where my application can receive all of those request without having to send a response (I will respond but want the ability to process multiple requests at a time to reduce the impact of internal latency). So the web server library will need to support the following flow 1) HTTP Client transmits http request 1 2) HTTP Client transmits http request 2 ... 3) Web Server Library receives request 1 and passes it to My Web Server App 4) My Web Server App receives request 1 and dispatches it to My System 5) Web Server receives request 2 and passes it to My Web Server App 6) My Web Server App receives request 2 and dispatches it to My System 7) My Web Server App receives response to request 1 from My System and passes it to Web Server 8) Web Server transmits HTTP response 1 to HTTP Client 9) My Web Server App receives response to request 2 from My System and passes it to Web Server 10) Web Server transmits HTTP response 2 to HTTP Client Hopefully this illustrates my requirement. There are two key points to recognise. Responses to the Web Server Library are asynchronous and there may be several HTTP requests passed to My Web Server App with responses outstanding. Additional requirements are Embeddable into an existing 'C' application Small footprint; I don't need all the functionality available in Apache etc. Efficient; will need to support thousands of requests a second Allows asynchronous responses to requests; their is a small latency to responses and given the required request throughput a synchronous architecture is not going to work for me. Support persistent TCP connections Support use with Server-Push Comet connections Open Source / GPL support for HTTPS Portable across linux, windows; preferably more. I will be very grateful for any recommendation Best Regards
