• Integrate BING API for Search inside ASP.Net web application

  - by sreejukg

  As you might already know, Bing is the Microsoft Search engine and is getting popular day by day. Bing offers APIs that can be integrated into your website to increase your website functionality. At this moment, there are two important APIs available. They are Bing Search API Bing Maps The Search API enables you to build applications that utilize Bing’s technology. The API allows you to search multiple source types such as web; images, video etc. and supports various output prototypes such as JSON, XML, and SOAP. Also you will be able to customize the search results as you wish for your public facing website. Bing Maps API allows you to build robust applications that use Bing Maps. In this article I am going to describe, how you can integrate Bing search into your website. In order to start using Bing, First you need to sign in to http://www.bing.com/toolbox/bingdeveloper/ using your windows live credentials. Click on the Sign in button, you will be asked to enter your windows live credentials. Once signed in you will be redirected to the Developer page. Here you can create applications and get AppID for each application. Since I am a first time user, I don’t have any applications added. Click on the Add button to add a new application. You will be asked to enter certain details about your application. The fields are straight forward, only thing you need to note is the website field, here you need to enter the website address from where you are going to use this application, and this field is optional too. Of course you need to agree on the terms and conditions and then click Save. Once you click on save, the application will be created and application ID will be available for your use. Now we got the APP Id. Basically Bing supports three protocols. They are JSON, XML and SOAP. JSON is useful if you want to call the search requests directly from the browser and use JavaScript to parse the results, thus JSON is the favorite choice for AJAX application. XML is the alternative for applications that does not support SOAP, e.g. flash/ Silverlight etc. SOAP is ideal for strongly typed languages and gives a request/response object model. In this article I am going to demonstrate how to search BING API using SOAP protocol from an ASP.Net application. For the purpose of this demonstration, I am going to create an ASP.Net project and implement the search functionality in an aspx page. Open Visual Studio, navigate to File-> New Project, select ASP.Net empty web application, I named the project as “BingSearchSample”. Add a Search.aspx page to the project, once added the solution explorer will looks similar to the following. Now you need to add a web reference to the SOAP service available from Bing. To do this, from the solution explorer, right click your project, select Add Service Reference. Now the new service reference dialog will appear. In the left bottom of the dialog, you can find advanced button, click on it. Now the service reference settings dialog will appear. In the bottom left, you can find Add Web Reference button, click on it. The add web reference dialog will appear now. Enter the URL as http://api.bing.net/search.wsdl?AppID=<YourAppIDHere>&version=2.2 (replace <yourAppIDHere> with the appID you have generated previously) and click on the button next to it. This will find the web service methods available. You can change the namespace suggested by Bing, but for the purpose of this demonstration I have accepted all the default settings. Click on the Add reference button once you are done. Now the web reference to Search service will be added your project. You can find this under solution explorer of your project. Now in the Search.aspx, that you previously created, place one textbox, button and a grid view. For the purpose of this demonstration, I have given the identifiers (ID) as txtSearch, btnSearch, gvSearch respectively. The idea is to search the text entered in the text box using Bing service and show the results in the grid view. In the design view, the search.aspx looks as follows. In the search.aspx.cs page, add a using statement that points to net.bing.api. I have added the following code for button click event handler. The code is very straight forward. It just calls the service with your AppID, a query to search and a source for searching. Let us run this page and see the output when I enter Microsoft in my textbox. If you want to search a specific site, you can include the site name in the query parameter. For e.g. the following query will search the word Microsoft from www.microsoft.com website. searchRequest.Query = “site:www.microsoft.com Microsoft”; The output of this query is as follows. Integrating BING search API to your website is easy and there is no limit on the customization of the interface you can do. There is no Bing branding required so I believe this is a great option for web developers when they plan for site search.

• Supervisor sentry-web exit status 1

  - by rockingskier

  I'm having problems getting Sentry (https://www.getsentry.com - not enough rep for a link) running as a service using supervisor. I can run Sentry in the command line and view it correctly in the browser but when it comes to supervisor I am completely in the dark. I shall try and give all the details I can Initial user warning By no means a server admin, just playing/learning in VirtualBox. Literally only just discovered supervisor from reading the Sentry documentation so I may well be making some obvious mistakes here. The setup: Ubuntu server 11.10 (fresh install, VirtualBox) virtualenv with Sentry and its dependencies. supervisor Instructions followed Supervisor with vanilla ini file Sentry/supervisor instructions My supervisor ini (Sentry section) [program:sentry-web] directory=/root/.virtualenvs/sentry/ command= start http /root/.virtualenvs/sentry/bin/sentry autostart=true autorestart=true redirect_stderr=true OK so here we go: When I run supervisord -n I get the following messages rather than a nice web interface to play with. 2012-04-12 23:48:09,024 CRIT Supervisor running as root (no user in config file) 2012-04-12 23:48:09,097 INFO RPC interface 'supervisor' initialized 2012-04-12 23:48:09,099 CRIT Server 'unix_http_server' running without any HTTP authentication checking 2012-04-12 23:48:09,100 INFO supervisord started with pid 17813 2012-04-12 23:48:10,126 INFO spawned: 'sentry-web' with pid 17816 2012-04-12 23:48:10,169 INFO exited: sentry-web (exit status 1; not expected) 2012-04-12 23:48:11,199 INFO spawned: 'sentry-web' with pid 17817 2012-04-12 23:48:11,238 INFO exited: sentry-web (exit status 1; not expected) 2012-04-12 23:48:13,269 INFO spawned: 'sentry-web' with pid 17818 2012-04-12 23:48:13,309 INFO exited: sentry-web (exit status 1; not expected) 2012-04-12 23:48:16,343 INFO spawned: 'sentry-web' with pid 17819 2012-04-12 23:48:16,389 INFO exited: sentry-web (exit status 1; not expected) 2012-04-12 23:48:17,394 INFO gave up: sentry-web entered FATAL state, too many start retries too quickly CRIT Supervisor running as root (no user in config file) suggests a big problem, probably shouldn't be running this as root? CRIT Server 'unix_http_server' running without any HTTP authentication checking Surely authentication is optional? INFO exited: sentry-web (exit status 1; not expected) *sad face* here.

• ASP.NET Web API - Screencast series Part 3: Delete and Update

  - by Jon Galloway

  We're continuing a six part series on ASP.NET Web API that accompanies the getting started screencast series. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. In Part 1 we looked at what ASP.NET Web API is, why you'd care, did the File / New Project thing, and did some basic HTTP testing using browser F12 developer tools. In Part 2 we started to build up a sample that returns data from a repository in JSON format via GET methods. In Part 3, we'll start to modify data on the server using DELETE and POST methods. So far we've been looking at GET requests, and the difference between standard browsing in a web browser and navigating an HTTP API isn't quite as clear. Delete is where the difference becomes more obvious. With a "traditional" web page, to delete something'd probably have a form that POSTs a request back to a controller that needs to know that it's really supposed to be deleting something even though POST was really designed to create things, so it does the work and then returns some HTML back to the client that says whether or not the delete succeeded. There's a good amount of plumbing involved in communicating between client and server. That gets a lot easier when we just work with the standard HTTP DELETE verb. Here's how the server side code works: public Comment DeleteComment(int id) { Comment comment; if (!repository.TryGet(id, out comment)) throw new HttpResponseException(HttpStatusCode.NotFound); repository.Delete(id); return comment; } If you look back at the GET /api/comments code in Part 2, you'll see that they start the exact same because the use cases are kind of similar - we're looking up an item by id and either displaying it or deleting it. So the only difference is that this method deletes the comment once it finds it. We don't need to do anything special to handle cases where the id isn't found, as the same HTTP 404 handling works fine here, too. Pretty much all "traditional" browsing uses just two HTTP verbs: GET and POST, so you might not be all that used to DELETE requests and think they're hard. Not so! Here's the jQuery method that calls the /api/comments with the DELETE verb: $(function() { $("a.delete").live('click', function () { var id = $(this).data('comment-id'); $.ajax({ url: "/api/comments/" + id, type: 'DELETE', cache: false, statusCode: { 200: function(data) { viewModel.comments.remove( function(comment) { return comment.ID == data.ID; } ); } } }); return false; }); }); So in order to use the DELETE verb instead of GET, we're just using $.ajax() and setting the type to DELETE. Not hard. But what's that statusCode business? Well, an HTTP status code of 200 is an OK response. Unless our Web API method sets another status (such as by throwing the Not Found exception we saw earlier), the default response status code is HTTP 200 - OK. That makes the jQuery code pretty simple - it calls the Delete action, and if it gets back an HTTP 200, the server-side delete was successful so the comment can be deleted. Adding a new comment uses the POST verb. It starts out looking like an MVC controller action, using model binding to get the new comment from JSON data into a c# model object to add to repository, but there are some interesting differences. public HttpResponseMessage<Comment> PostComment(Comment comment) { comment = repository.Add(comment); var response = new HttpResponseMessage<Comment>(comment, HttpStatusCode.Created); response.Headers.Location = new Uri(Request.RequestUri, "/api/comments/" + comment.ID.ToString()); return response; } First off, the POST method is returning an HttpResponseMessage<Comment>. In the GET methods earlier, we were just returning a JSON payload with an HTTP 200 OK, so we could just return the  model object and Web API would wrap it up in an HttpResponseMessage with that HTTP 200 for us (much as ASP.NET MVC controller actions can return strings, and they'll be automatically wrapped in a ContentResult). When we're creating a new comment, though, we want to follow standard REST practices and return the URL that points to the newly created comment in the Location header, and we can do that by explicitly creating that HttpResposeMessage and then setting the header information. And here's a key point - by using HTTP standard status codes and headers, our response payload doesn't need to explain any context - the client can see from the status code that the POST succeeded, the location header tells it where to get it, and all it needs in the JSON payload is the actual content. Note: This is a simplified sample. Among other things, you'll need to consider security and authorization in your Web API's, and especially in methods that allow creating or deleting data. We'll look at authorization in Part 6. As for security, you'll want to consider things like mass assignment if binding directly to model objects, etc. In Part 4, we'll extend on our simple querying methods form Part 2, adding in support for paging and querying.

• Web Development Trends: Mobile First, Data-Oriented Development, and Single Page Applications

  - by dwahlin

  I recently had the opportunity to give a keynote talk at an Intel conference about key trends in the world of Web development that I feel teams should be taking into account with projects. It was a lot of fun and I had the opportunity to talk with a lot of different people about projects they’re working on. There are a million things that could be covered for this type of talk (HTML5 anyone?) but I only had 60 minutes and couldn’t possibly cover them all so I decided to focus on 3 key areas: mobile, data-oriented development, and SPAs. The talk was geared toward introducing people (many who weren’t Web developers) to topics such as mobile first development (demos showed a few tools to help here), responsive design techniques, data binding techniques that can simplify code, and Single Page Application (SPA) benefits. Links to code demos shown during the presentation can be found at the end of the slide deck. Web Development Trends - What's New in the World of Web Development by Dan Wahlin

• Custom Profile Provider with Web Deployment Project

  - by Ben Griswold

  I wrote about implementing a custom profile provider inside of your ASP.NET MVC application yesterday. If you haven’t read the article, don’t sweat it.  Most of the stuff I write is rubbish anyway. Since you have joined me today, though, I might as well offer up a little tip: you can run into trouble, like I did, if you enable your custom profile provider inside of an application which is deployed using a Web Deployment Project.  Everything will run great on your local machine and you’ll probably take an early lunch because you got the code running in no time flat and the build server is happy and all tests pass and, gosh, maybe you’ll just cut out early because it is Friday after all.  But then the first user hits the integration machine and, that’s right, yellow screen of death. Lucky you, just as you’re walking out the door, the user kindly sends the exception message and stack trace: Value cannot be null. Parameter name: type Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Stack Trace: [ArgumentNullException: Value cannot be null. Parameter name: type] System.Activator.CreateInstance(Type type, Boolean nonPublic) +2796915 System.Web.Profile.ProfileBase.CreateMyInstance(String username, Boolean isAuthenticated) +76 System.Web.Profile.ProfileBase.Create(String username, Boolean isAuthenticated) +312 User error?  Not this time. Damn! One hour later… you notice the harmless “Treat as library component (remove the App_Code.compiled file)” setting on the Output Assemblies Tab of your Web Deployment Project. You have no idea why, but you uncheck it.  You test and everything works great both locally and on the integration machine.  Application users think you’re the best and you’re still going to catch the last half hour of happy hour.  Happy Friday.

• Use Microsoft PowerPivot to Access Salesforce.com Through the OData Connector

  - by dataintegration

  This article will explain how to connect to any of our OData Connectors with Microsoft Excel's PowerPivot business intelligence tool. While the example will use the Salesforce Connector, the same process can be followed for any of the RSSBus OData Connectors. Step 1: Download and install both the Salesforce Connector from RSSBus and PowerPivot for Excel from Microsoft. Step 2: Next you will want to configure the Salesforce Connector to connect with your Salesforce account. If you browse to the Help tab in the Salesforce Connector application, there is a link to the Getting Started Guide which will walk you through setting up the Salesforce Connector. Step 3: Once you have successfully configured the Salesforce Connector application, you will want to open Excel and select the PowerPivot tab at the top of the window. Step 4: Here you will click on the button labeled PowerPivot Window at the top left. Step 5: A new pop up will appear. Now select the option "From Data Feeds". Step 6: In the resulting Table Import Wizard you will enter the OData URL of the Salesforce Connector. You can find this by clicking on the Settings tab of the Salesforce Connector. It will look something like this: http://localhost:8181/sfconnector/data/conn/odata.rsc. You will also need to add authentication options in this step. To do this, click on the Advanced button and scroll down to the Security section of the resulting pop up window. Change the Integrated Security option to "Basic". You will also need to enter the User ID and Password of the user who has access to the Salesforce Connector. Step 7: When the connection to the Salesforce Connector is successful, click the Next button at the bottom of the window. Step 8: A table listing of the available tables will appear in the next window of the wizard. Here you will select which tables you want to import and click Finish. Step 9: If the import was successful, click Close and you are done! Your data is now in PowerPivot.

• Using MAC Authentication for simple Web API’s consumption

  - by cibrax

  For simple scenarios of Web API consumption where identity delegation is not required, traditional http authentication schemas such as basic, certificates or digest are the most used nowadays. All these schemas rely on sending the caller credentials or some representation of it in every request message as part of the Authorization header, so they are prone to suffer phishing attacks if they are not correctly secured at transport level with https. In addition, most client applications typically authenticate two different things, the caller application and the user consuming the API on behalf of that application. For most cases, the schema is simplified by using a single set of username and password for authenticating both, making necessary to store those credentials temporally somewhere in memory. The true is that you can use two different identities, one for the user running the application, which you might authenticate just once during the first call when the application is initialized, and another identity for the application itself that you use on every call. Some cloud vendors like Windows Azure or Amazon Web Services have adopted an schema to authenticate the caller application based on a Message Authentication Code (MAC) generated with a symmetric algorithm using a key known by the two parties, the caller and the Web API. The caller must include a MAC as part of the Authorization header created from different pieces of information in the request message such as the address, the host, and some other headers. The Web API can authenticate the caller by using the key associated to it and validating the attached MAC in the request message. In that way, no credentials are sent as part of the request message, so there is no way an attacker to intercept the message and get access to those credentials. Anyways, this schema also suffers from some deficiencies that can generate attacks. For example, brute force can be still used to infer the key used for generating the MAC, and impersonate the original caller. This can be mitigated by renewing keys in a relative short period of time. This schema as any other can be complemented with transport security. Eran Rammer, one of the brains behind OAuth, has recently published an specification of a protocol based on MAC for Http authentication called Hawk. The initial version of the spec is available here. A curious fact is that the specification per se does not exist, and the specification itself is the code that Eran initially wrote using node.js. In that implementation, you can associate a key to an user, so once the MAC has been verified on the Web API, the user can be inferred from that key. Also a timestamp is used to avoid replay attacks. As a pet project, I decided to port that code to .NET using ASP.NET Web API, which is available also in github under https://github.com/pcibraro/hawknet Enjoy!.

• Gamify your Web

  - by Isabel F. Peñuelas

  Yesterday Valencia welcomed the Gamification World Congress that I follow virtually through #GWC2012. BBVA, Iberia, Ligeresa, Axe, Wayra, ESADE, GlaxoSmithKline, Macmillan, Gamisfaction, Nomaders, Blaffin were among the companies presenting success stories on gaming. It has been proved that people remember things easily when an emotion is created. The marketing expectations around Gamification techniques have a lot to do with Neuromarketing theories. There are a lot of expectations on internal enterprise Gamification. In the public Web some sectors are taking the lead on following the trend. The Gartner Analyst Brian Burke opened another Gamification recent event in Madrid remembering that “Gamification is mostly about Engagement”, and this can be applied both to customers or employees. Gamification and Banking The experience of the Spanish Financial Group BBVA that just launched BBVA Game was also presented a week ago at the BBVA Innovation Centre during the event “Gamification & Banking: a fad or a serious business?” . One of the objectives of the BBVA Game was to double the name of registered users. “People like the efficiency of the online channel want to keep a one-to-one contact with the brand”-explained Bernardo Crespo. Another interested data coming out the BBVA presentation was that “only 20% of Spanish users –out of the total holders of Bank Accounts in the country- is familiar with the use of a Web Site to consult their bank accounts”, the project aims also to reverse this situation helping people to learn making a heavy use of the Video in the gaming context. In general Banking presenters seem to agree that Gamification techniques are helping to increase the time spent on the Web. Gamification and Health Using Gamification techniques for chronic illness rehabilitation was another topic of the World Congress. Here you can find some ideas and experiences What can games do for the health (In Spanish) I have personally started my own mental-health gaming project at http://www.lumosity.com/ Gamification in the Enterprise I really recommend Reading this excellent post of Ultan ÓBroin my Introduction to Gamification and Applications. Employee´s motivation and learning are experiencing a 360º turn and it looks than some of us will become soon the Dragon of the year instead of the Employee of the Year. Using Web 2.0 Tools for Gamification Projects  What type of tools do we need for a quick-win Gamification project? To certain extend Gamification can be considered an evolution of the participative Web. Badging, avatars, points and awards, leader boards, progress charts, virtual currencies, gifting and giving challenges and quests are common components and elements. The Web is offering new development frameworks to that purpose as this Avatar Framework from Paypal or Badgeville to include in web applications. Besides, tools to create communities around a game are required to comment, share and vote players as well as for an efficient multimedia management. Due to its entirely open architecture, its community features, and its multimedia and imaging solutions is were I see WebCenter as a tool helping brands to success.

• How to Setup an Active Directory Domain-Week 26

  - by OWScott

  Today's lesson covers how to create an Active Directory domain and join a member server to it. This week's topic takes a slightly different turn from the normally IIS related topics, but this is key video to help setup either a test or production environment that requires Active Directory. Part of being a web administrator is understanding the servers and how they interact with each other. This week’s lesson takes a different path than usual and covers how to create an Active Directory domain and how to join a member computer to that domain. In less than 13 minutes we complete the entire process, end to end. An understanding of Active Directory is useful, whether it’s simply to setup a test lab, or to learn more so that you can manage a production domain environment. This week starts a mini-series on web farms. Today’s lesson is on setting up a domain which is a necessary prerequisite for next week which will be on Distributed File System Replication (DFS-R), a useful technology for web farms. Upcoming lessons will cover shared configuration, Application Request Routing (ARR), and more. Additionally, this video introduces us to Vaasnet (www.vaasnet.com), a service that allows the web pro to gain immediate access to an entire lab environment for situations such as these. This is week 26 (the middle week!) of a 52 week series for the Web Pro. Past and future videos can be found here: http://dotnetslackers.com/projects/LearnIIS7/ You can find this week’s video here.

This is a basic demo to try and utilize a separate project library called TiledLib. I have four projects overall: TiledLib (C# Class Library) TiledTest (Windows Game) TiledTestContent (Content) TMX CP Ext (Content Pipeline Extension Library) TiledLib contains MapContent which is throwing the error, however I believe this may just be a generic error with a deeper root problem. EMX CP Ext contains one file: MapProcessor.cs using System; using System.Collections.Generic; using System.Linq; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Content.Pipeline; using Microsoft.Xna.Framework.Content.Pipeline.Graphics; using Microsoft.Xna.Framework.Content.Pipeline.Processors; using Microsoft.Xna.Framework.Content; using TiledLib; namespace TMX_CP_Ext { // Each tile has a texture, source rect, and sprite effects.

ExternalReference<Texture2DContent> textureContent = null; Rectangle sourceRect = new Rectangle(); // iterate all the tile sets foreach (var tileSet in input.TileSets) { // if our tile index is in this set if (tileIndex - tileSet.FirstId < tileSet.Tiles.Count) { // store the texture content and source rectangle textureContent = tileSet.Texture; sourceRect = tileSet.Tiles[(int)(tileIndex - tileSet.FirstId)].Source; // and break out of the foreach loop break; } } // now insert the tile into our output outLayer.Tiles[i] = new DemoMapTileContent { Texture = textureContent, SourceRectangle = sourceRect, SpriteEffects = spriteEffects }; } // add the layer to our output output.Layers.Add(outLayer); } } // return the output object. because we have ContentSerializerRuntimeType attributes on our // objects, we don't need a ContentTypeWriter and can just use the automatic serialization. return output; } } } TiledLib contains a large amount of files including MapContent.cs using System; using System.Collections.Generic; using System.Globalization; using System.Xml; using Microsoft.Xna.Framework.Content.Pipeline; namespace TiledLib { public enum Orientation : byte { Orthogonal, Isometric, } public class MapContent { public string Filename; public string Directory; public string Version = string.Empty; public Orientation Orientation; public int Width; public int Height; public int TileWidth; public int TileHeight; public PropertyCollection Properties = new PropertyCollection(); public List<TileSetContent> TileSets = new List<TileSetContent>(); public List<LayerContent> Layers = new List<LayerContent>(); public MapContent(XmlDocument document, ContentImporterContext context) { XmlNode mapNode = document["map"]; Version = mapNode.Attributes["version"].Value; Orientation = (Orientation)Enum.Parse(typeof(Orientation), mapNode.Attributes["orientation"].Value, true); Width = int.Parse(mapNode.Attributes["width"].Value, CultureInfo.InvariantCulture); Height = int.Parse(mapNode.Attributes["height"].Value, CultureInfo.InvariantCulture); TileWidth = int.Parse(mapNode.Attributes["tilewidth"].Value, CultureInfo.InvariantCulture); TileHeight = int.Parse(mapNode.Attributes["tileheight"].Value, CultureInfo.InvariantCulture); XmlNode propertiesNode = document.SelectSingleNode("map/properties"); if (propertiesNode != null) { Properties = new PropertyCollection(propertiesNode, context); } foreach (XmlNode tileSet in document.SelectNodes("map/tileset")) { if (tileSet.Attributes["source"] != null) { TileSets.Add(new ExternalTileSetContent(tileSet, context)); } else { TileSets.Add(new TileSetContent(tileSet, context)); } } foreach (XmlNode layerNode in document.SelectNodes("map/layer|map/objectgroup")) { LayerContent layerContent; if (layerNode.Name == "layer") { layerContent = new TileLayerContent(layerNode, context); } else if (layerNode.Name == "objectgroup") { layerContent = new MapObjectLayerContent(layerNode, context); } else { throw new Exception("Unknown layer name: " + layerNode.Name); } // Layer names need to be unique for our lookup system, but Tiled // doesn't require unique names. string layerName = layerContent.Name; int duplicateCount = 2; // if a layer already has the same name... if (Layers.Find(l => l.Name == layerName) != null) { // figure out a layer name that does work do { layerName = string.Format("{0}{1}", layerContent.Name, duplicateCount); duplicateCount++; } while (Layers.Find(l => l.Name == layerName) != null); // log a warning for the user to see context.Logger.LogWarning(string.Empty, new ContentIdentity(), "Renaming layer \"{1}\" to \"{2}\" to make a unique name.", layerContent.Type, layerContent.Name, layerName); // save that name layerContent.Name = layerName; } Layers.Add(layerContent); } } } } I'm lost as to why this is failing. Thoughts? -- EDIT -- After playing with it a bit, I would think it has something to do with referencing the projects. I'm already referencing the TiledLib within my main windows project (TiledTest). However, this doesn't seem to make a difference. I can place the dll generated from the TiledLib project into the debug folder of TiledTest, and this causes it to generate a different error: Error loading "desert".

The TiledLib I am utilizing is from Nick Gravelyn, and can be found here: https://bitbucket.org/nickgravelyn/tiledlib. The demo it comes with works fine, and yet in recreating I always run into this error.

• Extracting data from internet

  - by Ankiov Spetsnaz

  I would like to extract data from internet like www.mozenda.com does but I want to write my own program to do that. Specific data I'm looking for is various event data. Based on my research, I think custom web crawler is my answer but I Would like to confirm the answer and see if there are any suggestion to make custom web crawlers if web crawler indeed is an answer. Personally, I would prefer Java and I'm planning on using Glassfish technology if that matters...

• Anonymous Access and Sharepoint Web Services

  - by Stacy Vicknair

  A month or so ago I was working on a feature for a project that required a level of anonymity on the Sharepoint site in order to function. At the same time I was also working on another feature that required access to the Sharepoint search.asmx web service. I found out, the hard way, that the Sharepoint Web Services do not operate in an expected way while the IIS site is under anonymous access. Even though these web services expect requests with certain permissions (in theory) they never attempt to request those credentials when the web service is contacted. As a result the services return a 401 Unauthorized response. The fix for my situation was to restrict anonymous access to the area that needed it (in this case the control in question had support for being used in an ASP.NET app that I could throw in a virtual directory). After that I removed anonymous access from IIS for the site itself and the QueryService requests were working once more. Here’s a related article with a bit more depth about a similar experience: http://chrisdomino.com/Blog/Post/401-Reasons-Why-SharePoint-Web-Services-Don-t-Work-Anonymously?Length=4 Technorati Tags: Sharepoint,QueryService,WSS,IIS,Anonymous Access

• Understanding each other in web development

  - by Pete Hotchkin

  During my career I have been lucky enough to work in several different roles within web development with many extremely talented people, from incredible designers who were passionate about the placement of every pixel right through to server administrators and DBAs who were always measuring the improvements they were making to their queries in the smallest possible unit. The problem I always faced was that more often than not I was stuck in the middle trying to mediate between these different functions and enable each side to understand the other’s point of view. The main areas of contention that there have always been between these functional groups in my experience have been at 2 key points: during the build phase and then when there is a problem post-build. During both of these times it is often easier for someone to pass the buck onto someone else than spend the time to understand the other person’s perspective. Below is a quick look at two upcoming tools that will not only speed up the build phase for each function, but  also help when it comes to the issues faced once a site has been pushed live. In my experience a web project goes through several phases of development. The first of these is design, generally handled as Photoshop files which are then passed onto a front-end developer. This is the first point at which heated discussions can arise. One problem I’ve seen several times is that the designer doesn’t fully understand the platform constraints that need to be considered, and as a result has designed something that does not translate very well or is simply not possible. Working at Red Gate, I am lucky enough to be able to meet some amazing people and this happened just the other day when I was introduced to Neil Kinnish and Pete Nelson, the creators of what I believe could be a great asset in this designer-developer relationship, Mixture. Mixture allows the front end developer to quickly prototype a web page with built-in frameworks such as bootstrap. It’s not an IDE however, it just sits there in the background and monitors the project files in the background so every time you save a file from your favorite IDE, it will compile things like LESS, compact your JavaScript and the automatically refresh your test browser so you can see the changes instantly. I think one of the best parts of this however is a single button that pushes the changed files up to the web so the designer can instantly see how far the developer has got and the problem that he is facing at that time without the need to spend time setting up a remote server. I can see this being a real asset to remote teams where there needs to be a compromise between the designer and the front-end developer, or just to allow the designer to see how the build is progressing and suggest small alterations. Once the design has been built into the front end the designer’s job is generally done and there are no other points of contention between the designer and the other functions involved in building these web projects. As the project moves into the stage of integrating it into the back end and deploying it to the production server other functions start to be pulled in and other issues arise such as the back-end developer understanding the frameworks that they are using such as the routes that are in place in an MVC application or the number of database calls that the ORM layer is actually making. There are many tools out there that can actually help with these problems such as mini profiler that gives you a quick snapshot of what is going on directly in the browser. For a slightly more in-depth look at what is happening and to gain a deeper understanding of an application you may be working on though, you may want to consider Glimpse. Created by Nik and Anthony, it is an application that sits at the bottom of your browser (installed via NuGet) which can show you information about how your application is pieced together and how the information on screen is being delivered as it happens. With a wealth of community-built plugins such as one for nHibernate and linq2SQL (full list of plugins on NuGet). It can be customized directly to your own setup to truly delve into the code to see what is happening, and can help to reduce the number of confusing moments about whether it is your code that is going wrong or whether there is something more sinister happening directly on the server. All the tools that I have mentioned in this post help to do one thing above all, and that is to ease the barrier of understanding between the different functions that are involved in building and maintaining a web application. In my experience it is very easy to say “Well, that’s not my problem”, simply because the two functions involved don’t truly understand the other’s point of view. Software should not only be seen as a way to streamline our own working process or as a debugging tool but also a communication aid to improve the entire lifecycle of a web project. Glimpse is actually the project that I am the designer on and I would love to get your feedback if you do decide to try it out or if you would like to share your own experiences of working on web projects please fill in your details at https://www.surveymk.com/s/joinGlimpse  or add a comment below and I will get in touch with you.

• IIS can't load Oracle.Web assembly (for ASP.NET membership provider)

  - by Konamiman

  I am trying to configure an IIS web site to use an Oracle database for ASP.NET membership, but I can't get it to work. IIS doesn't seem to be able to load the assembly containing the Oracle membership provider. That's what I have so far: An Oracle 10g database online and with all the tables for ASP.NET membership created. Windows 2008 R2 Standard with the web server role installed, including support for ASP.NET. Oracle 11g Release 2 ODAC 11.2.0.1.2 installed. The installed components are: Oracle data provider for .NET, Oracle providers for ASP.NET, Oracle instant client. The default web site on IIS (I am using that for testing) has the following web.config file: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.web> <membership defaultProvider="OracleMembershipProvider"> <providers> <remove name="SqlMembershipProvider" /> <add name="OracleMembershipProvider" type="Oracle.Web.Security.OracleMembershipProvider, Oracle.Web, Version=2.112.1.2, Culture=neutral, PublicKeyToken=89b483f429c47342" connectionStringName="OracleServer" /> </providers> </membership> </system.web> </configuration> (Additional attributes on the "add" element omitted for brevity. Also, the connection string is defined for the whole server.) The Oracle.Web.dll file is on the GAC. That's the relevant part of the C:\Windows\Assembly folder: The web site application pool is configured for .NET 2.0, and has 32-bit applications enabled. I have allowed untrusted providers in the IIS' administration.config file (just for the sake of testing, I'll explicitly add the assembly to the trusted providers list later). With all of this setup in place, when I click on the ".NET Users" icon on the IIS manager, I get a warning about the provider having too much privileges, and when I accept I get the following message: There was an error while performing this operation. Details: Could not load file or assembly 'Oracle.Web, Version=2.112.1.2, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified. So, what am I missing? How can I get the Oracle membership provider to work? Thank you! UPDATE: It seems that the problem is not with IIS itself, but with the IIS administrator only. When using the web site configuration tool provided by Visual Studio, everything works fine.
