• Exciting product releases (and one disappointing thing) with Mix10

  - by Jeff

  Sadly, I'm not at Mix this year, for the first time in a few years. It's a little harder to go if you work for Microsoft, oddly enough. And then there's this little guy next to me, who at ten days old really needs his daddy to be around! But oh, the excitement of what Microsoft has in store! It's great to finally see all of these major releases coming together for Microsoft developer products. There is a great deal of excitement among people internally no matter where you work, because there is so much cool stuff in the pipe. In case you live under a rock...Visual Studio 2010 - Great to see all of the positive feedback on the Twitter and what not. I've been using it on one of my home products for awhile, and I really like it. The newer nightly builds of ReSharper also seem to be gaining speed in quality as well. I like the new debugging features, and the text readability is not imagined. Love it.Silverlight 4 - I've been running a couple of minor SL3 apps on my personal sites for awhile now, and I'm thrilled with the platform. With a couple of key concepts down, .NET folk like you and me can do some stellar things with this, and if you're a Mac nerd (like me), it's all kinds of awesome to be able to build stuff for it without the agony of Objective-C and X Code.Windows Phone 7 Series - A few weeks ago you got to see the shiny new UI that went beyond the icon grid, and now you've got the developer story as well. That I can adapt my existing Silverlight apps with minimal effort to work on the phone is pretty powerful. Millions of .NET devs just because phone developers, using the tools they already know. How great is that?ASP.NET MVC2 - The final bits shipped last week, and there was much rejoicing. I love this framework because of the testability and the real ability to get to the true mechanics of HTTP. The other cool thing is the speed at which the framework has evolved. v2 in less than a year is pretty "un-Microsoft" in a lot of eyes.The video of keynotes and sessions is starting to appear on the Mix site, but for reasons I can't understand, they're WMV downloads. For real? Not that helpful for Mac folk. Why wouldn't they be using a Silverlight player?In any case, the thing that continues to motivate me is that getting what you imagine on to the Internet gets easier every year. This is not a new revelation for me. I've only been at Microsoft for four months, but I've felt this way for years. I'm thrilled to be a part of it.

• At $20/month Windows Azure host my website with 99.97% uptime

  - by Gopinath

  Couple of years ago a reliable and decent performing Windows hosting was not affordable to many enthusiastic developers who want to try a startup idea or build a hobby site. I tried to start an ASP.NET website few years ago to provide services like – Mobile Tracing, Vehicle Tracing. But due to high cost of Windows hosting I developed those services using PHP (not an easy task for .NET developer) and hosted on them Linux servers.  But with recent evolution of Windows Azure, hosting ASP.NET websites on highly reliable servers is affordable. Today anyone can host a high responsive and available ASP.NET website for just $20/month using Windows Azure. My website coziie.com is running on Windows Azure and serves close to quarter millions visitors a month with 99.97% of uptime and most of the page load times are less than 3 seconds. All I spend to run this website is just around $20, if you translate it to India rupees its roughly Rs.1000. The web sever of coziie.com is powered by a single Extra Small Web role instance and the backend is powered by a SQL Azure instance. Azure is quite impressive to provide 99.97% of uptime. Response times during peak are around 3 seconds and on nomarl loads it is around 1.5 seconds. Here is the report of uptime provided by Royal Pingdom over last one year For just $20/month Windows Azure takes care of the following apart from hosting Patches up Windows OS to the latest version Upgrades ASP.NET to the latest version – coziie.com is running on ASP.NET MVC 3 and soon I’ll upgrade it to ASP.NET MVC 4 Hosts data on latest and best version Sql Server database SQL Azure maintains 3 copies of database and automatically recovers in case of server failures and disasters. I never worry about database backups/restore. Provides staging environment for deploying applications for testing purpose and move them to production – I upgrade  twice a month on average With Windows Azure I no longer focus on server maintenance or data backups. They are taken up by Microsoft team and I just focus on building my website. Wish there is a low cost Linux version of Windows Azure so that I can stop worrying about server maintenance of this blog!! If you are looking for a Windows hosting, look no further than Windows Azure. If you find $20/month is a bit expensive to start with you may explore Azure Website (sort of shared hosted environment) which is free to start with and as your traffic grows you can move to paid hosting.

• Object of type 'customObject' cannot be converted to type 'customObject'.

  - by Phani Kumar PV

  i am receiving the follwing error when i am invoking a custom object "Object of type 'customObject' cannot be converted to type 'customObject'." Following is the scenario when i am getting the error i am invoking a method in a dll dynamically. Load an assembly CreateInstance.... calling MethodInfo.Invoke() passing int, string as a parameter for my method is working fine = No exceptions are thrown. But if I try and pass a one of my own custom class objects as a parameter, then I get an ArgumentException exception, and it is not either an ArgumentOutOfRangeException or ArgumentNullException. "Object of type 'customObject' cannot be converted to type 'customObject'." I am doing this in a web application. The class file containing the method is in a different proj . also the custom object is a sepearte class in the same file. there is no such thing called a static aseembly in my code. I am trying to invoke a webmethod dynamically. this webmethod is having the customObject type as an input parameter. So when i invoke the webmethod i am dynamically creating the proxy assembly and all. From the same assembly i am trying to create an instance of the cusotm object assinging the values to its properties and then passing this object as a parameter and invoking the method. everything is dynamic and nothing is created static.. :( add reference is not used. Following is a sample code i tried to create it public static object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args) { System.Net.WebClient client = new System.Net.WebClient(); //-Connect To the web service using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl")) { //--Now read the WSDL file describing a service. ServiceDescription description = ServiceDescription.Read(stream); ///// LOAD THE DOM ///////// //--Initialize a service description importer. ServiceDescriptionImporter importer = new ServiceDescriptionImporter(); importer.ProtocolName = "Soap12"; // Use SOAP 1.2. importer.AddServiceDescription(description, null, null); //--Generate a proxy client. importer.Style = ServiceDescriptionImportStyle.Client; //--Generate properties to represent primitive values. importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties; //--Initialize a Code-DOM tree into which we will import the service. CodeNamespace nmspace = new CodeNamespace(); CodeCompileUnit unit1 = new CodeCompileUnit(); unit1.Namespaces.Add(nmspace); //--Import the service into the Code-DOM tree. This creates proxy code //--that uses the service. ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1); if (warning == 0) //--If zero then we are good to go { //--Generate the proxy code CodeDomProvider provider1 = CodeDomProvider.CreateProvider("CSharp"); //--Compile the assembly proxy with the appropriate references string[] assemblyReferences = new string[5] { "System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll" }; CompilerParameters parms = new CompilerParameters(assemblyReferences); CompilerResults results = provider1.CompileAssemblyFromDom(parms, unit1); //-Check For Errors if (results.Errors.Count > 0) { StringBuilder sb = new StringBuilder(); foreach (CompilerError oops in results.Errors) { sb.AppendLine("========Compiler error============"); sb.AppendLine(oops.ErrorText); } throw new System.ApplicationException("Compile Error Occured calling webservice. " + sb.ToString()); } //--Finally, Invoke the web service method Type foundType = null; Type[] types = results.CompiledAssembly.GetTypes(); foreach (Type type in types) { if (type.BaseType == typeof(System.Web.Services.Protocols.SoapHttpClientProtocol)) { Console.WriteLine(type.ToString()); foundType = type; } } object wsvcClass = results.CompiledAssembly.CreateInstance(foundType.ToString()); MethodInfo mi = wsvcClass.GetType().GetMethod(methodName); return mi.Invoke(wsvcClass, args); } else { return null; } } } I cant find anything static being done by me. any help is greatly appreciated.

• How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment [closed]

  - by lmttag

  Possible Duplicate: How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment We have an ASP.NET Web API server that serves up a SQL Server data driven website. The API uses JSON to transfer data from SQL Server to the front end. We need to move it to an internal production environment (nothing will be exposed on the public Internet) and we’re having problems - or just not understanding what needs to be done. There are two domains: The corporate domain - where all users login normally. The process domain - contains the database the Web API needs to access. The IT staff wants to put a DMZ between the two domains to house the IIS app and shield the users on the corporate domain from having access into the process domain directly. The ideal configuration is: corp domain (end users) <–> firewall (open port 80) <–> DMZ (web server running IIS) <–> firewall (open port 80 or 1433????) <–> process domain (IIS for Web API and SQL Server) We don’t really understand how to deploy our browser/Web API application in this scenario. Do we need to break up our application so that all the client code is on the IIS server in the DMZ, while the Web API gets installed on the server in the process domain? Does the entire app (client code and Web API) stay together on the IIS server in the DMZ, which then somehow accesses the SQL Server instance to get data? From the IIS server and app in the DMZ, would you simply access the Web API on the server in the process domain by going to http://server/appname/api/getitmes? In the second firewall between the DMZ and the process domain, would you have to open port 1433 or just port 80 since the Web API is a HTTP endpoint? Or, is there some better way of deployment (i.e., how ASP.NET Web API single page applications written all in HTML5 and JavaScript supposed to be deployed to production environments?)? NB: The servers are Win2k8 R2, SQL Server 2k8 R2, and IIS 7.5.

• Differentiate procedural language(c) from oop languages(c++)

  - by niko

  I have been trying to differentiate c and c++(or oop languages) but I don't understand where the difference is. Note I have never used c++ but I asked my friends and some of them to differentiate c and c++ They say c++ has oop concepts and also the public, private modes for definition of variables and which c does not have though. Seriously I have done vb.net programming for a while 2 to 3 months, I never faced a situation to use class concepts and modes of definition like public and private. So I thought what could be the use for these? My friend explained me a program saying that if a variable is public, it can be accessed anywhere I said why not declare it as a global variable like in c? He did not get back to my question and he said if a variable is private it cannot be accessed by some other functions I said why not define it as a local variable, even these he was unable to answer. No matter where I read private variables cannot be accessed whereas public variables can be then why not make public as global and private as local whats the difference? whats the real use of public and private ? please don't say it can be used by everyone, I suppose why not we use some conditions and make the calls? I have heard people saying security reasons, a friend said if a function need to be accessed it should be inherited first. He explained saying that only admin should be able to have some rights and not all so that functions are made private and inherited only by the admin to use Then I said why not we use if condition if ( login == "admin") invoke the function he still did not answer these question. Please clear me with these things, I have done vb.net and vba and little c++ without using oop concepts because I never found their real use while I was writing the code, I'm a little afraid am I too back in oop concepts?

• Is this possible?

  - by PythonNewbie2

  Hello, I'm exploring some technologies and JSP with JSF 2.0 and Primefaces seems really cool. I'm new to all of these, but I'm a fast learner. I wondering if I can create the web app I want withh JSP/JSF/Primefaces or should I be looking to different technologies? If I should, which ones do you recommend? Here's a basic description of the app: Users log in with their username and password (maybe I can somehow incorporate google OPENID)? With a really nice UI, they will be presented a large list of questions specific to a certain category, for example, JSP. When they click on any of these questions, a little input opens up below it to allow the user to put in a link. If the link they enter has the same question on that webpage the URL points to, they will be awarded one point. This question then disappears and gets added to a different page that has a list of all correctly linked questions. On the right side of the screen, there will be a leaderboard with the usernames of the people with the top ten points. Is this possible with JSP/JSF/Primefaces, or should I be looking elsewhere for a different web technology? The idea is relatively simple - to be able to compile links to external websites for specific questions. I know I can build the UI easily with Primefaces. What I'm not sure is if JSP/JSF gives the ability to parse HTML at a certain URL to see if it contains words. I can do this with python easily by using urllib. Any help would be appreciated!!! What would be more helpful than a "Yes" or "No" answer would be links to where I can see sample code of external HTML parsing. Your input is truly appreciated! Thanks!

• Is Play Framework good for doing some logic parallely?

  - by pmichna

  I'm going to build a web application that's going to host urban games. A user visits my website, clicks "Start game" and starts receiving some SMS messages when gets to some location and has to answer them to get points. My question: is Play suitable for this kind of application? From what I've read I know for sure it's ok for traditional web applications: user interface for same data storage and manipulation. But what if after clicking the "start button" some logic has to go on its own course? How would I handle parallely checking geolocation of the players (I have API for that)? I guess in some threads that would ping them every ~5 sec. and do some processing but is it possible to just "disconnect" them from the main user interface? So to sum up: I want an application written in Play that starts a separate thread for a game after clicking "start game" and other users are able to view their data (statisctics etc.), while the threads work their way with the game logic. I found something like jobs but they are documented for version 1.2 (current one is 2.2). Sorry for my somewhat fuzzy explenation, I tried to do my best.

• Google and Bing Map APIs Compared

  - by SGWellens

  At one of the local golf courses I frequent, there is an open grass field next to the course. It is about eight acres in size and mowed regularly. It is permissible to hit golf balls there—you bring and shag our own balls. My golf colleagues and I spend hours there practicing, chatting and in general just wasting time. One of the guys brings Ginger, the amazing, incredible, wonder dog. Ginger is a Portuguese Pointer. She chases squirrels, begs for snacks and supervises us closely to make sure we don't misbehave.     Anyway, I decided to make a dedicated web page to measure distances on the field in yards using online mapping services. I started with Google maps and then did the same application with Bing maps. It is a good way to become familiar with the APIs. Here are images of the final two maps: Google:  Bing:   To start with online mapping services, you need to visit the respective websites and get a developers key. I pared the code down to the minimum to make it easier to compare the APIs. Google maps required this CSS (or it wouldn't work): <style type="text/css">     html     {         height: 100%;     }       body     {         height: 100%;         margin: 0;         padding: 0;     } Here is how the map scripts are included. Google requires the developer Key when loading the JavaScript, Bing requires it when the map object is created: Google: <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=XXXXXXX&libraries=geometry&sensor=false" > </script> Bing: <script  type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"> </script> Note: I use jQuery to manipulate the DOM elements which may be overkill, but I may add more stuff to this application and I didn't want to have to add it later. Plus, I really like jQuery. Here is how the maps are created: Common Code (the same for both Google and Bing Maps):     <script type="text/javascript">         var gTheMap;         var gMarker1;         var gMarker2;           $(document).ready(DocLoaded);           function DocLoaded()         {             // golf course coordinates             var StartLat = 44.924254;             var StartLng = -93.366859;               // what element to display the map in             var mapdiv = $("#map_div")[0];   Google:         // where on earth the map should display         var StartPoint = new google.maps.LatLng(StartLat, StartLng);           // create the map         gTheMap = new google.maps.Map(mapdiv,             {                 center: StartPoint,                 zoom: 18,                 mapTypeId: google.maps.MapTypeId.SATELLITE             });           // place two markers         marker1 = PlaceMarker(new google.maps.LatLng(StartLat, StartLng + .0001));         marker2 = PlaceMarker(new google.maps.LatLng(StartLat, StartLng - .0001));           DragEnd(null);     } Bing:         // where on earth the map should display         var StartPoint = new  Microsoft.Maps.Location(StartLat, StartLng);           // create the map         gTheMap = new Microsoft.Maps.Map(mapdiv,             {                 credentials: 'Asbsa_hzfHl69XF3wxBd_WbW0dLNTRUH3ZHQG9qcV5EFRLuWEaOP1hjWdZ0A0P17',                 center: StartPoint,                 zoom: 18,                 mapTypeId: Microsoft.Maps.MapTypeId.aerial             });             // place two markers         marker1 = PlaceMarker(new Microsoft.Maps.Location(StartLat, StartLng + .0001));         marker2 = PlaceMarker(new Microsoft.Maps.Location(StartLat, StartLng - .0001));           DragEnd(null);     } Note: In the Bing documentation, mapTypeId: was missing from the list of options even though the sample code included it. Note: When creating the Bing map, use the developer Key for the credentials property. I immediately place two markers/pins on the map which is simpler that creating them on the fly with mouse clicks (as I first tried). The markers/pins are draggable and I capture the DragEnd event to calculate and display the distance in yards and draw a line when the user finishes dragging. Here is the code to place a marker: Google: // ---- PlaceMarker ------------------------------------   function PlaceMarker(location) {     var marker = new google.maps.Marker(         {             position: location,             map: gTheMap,             draggable: true         });     marker.addListener('dragend', DragEnd);     return marker; }   Bing: // ---- PlaceMarker ------------------------------------   function PlaceMarker(location) {     var marker = new Microsoft.Maps.Pushpin(location,     {         draggable : true     });     Microsoft.Maps.Events.addHandler(marker, 'dragend', DragEnd);     gTheMap.entities.push(marker);     return marker; } Here is the code than runs when the user stops dragging a marker: Google: // ---- DragEnd -------------------------------------------   var gLine = null;   function DragEnd(Event) {     var meters = google.maps.geometry.spherical.computeDistanceBetween(marker1.position, marker2.position);     var yards = meters * 1.0936133;     $("#message").text(yards.toFixed(1) + ' yards');    // draw a line connecting the points     var Endpoints = [marker1.position, marker2.position];       if (gLine == null)     {         gLine = new google.maps.Polyline({             path: Endpoints,             strokeColor: "#FFFF00",             strokeOpacity: 1.0,             strokeWeight: 2,             map: gTheMap         });     }     else        gLine.setPath(Endpoints); } Bing: // ---- DragEnd -------------------------------------------   var gLine = null;   function DragEnd(Args) {    var Distance =  CalculateDistance(marker1._location, marker2._location);      $("#message").text(Distance.toFixed(1) + ' yards');       // draw a line connecting the points    var Endpoints = [marker1._location, marker2._location];           if (gLine == null)    {        gLine = new Microsoft.Maps.Polyline(Endpoints,            {                strokeColor: new Microsoft.Maps.Color(0xFF, 0xFF, 0xFF, 0),  // aRGB                strokeThickness : 2            });          gTheMap.entities.push(gLine);    }    else        gLine.setLocations(Endpoints);  }   Note: I couldn't find a function to calculate the distance between points in the Bing API, so I wrote my own (CalculateDistance). If you want to see the source for it, you can pick it off the web page. Note: I was able to verify the accuracy of the measurements by using the golf hole next to the field. I put a pin/marker on the center of the green, and then by zooming in, I was able to see the 150 markers on the fairway and put the other pin/marker on one of them. Final Notes: All in all, the APIs are very similar. Both made it easy to accomplish a lot with a minimum amount of code. In one aerial view, there are leaves on the tree, in the other, the trees are bare. I don't know which service has the newer data. Here are links to working pages: Bing Map Demo Google Map Demo I hope someone finds this useful. Steve Wellens   CodeProject

Here is the code to place a marker: Google: // ---- PlaceMarker ------------------------------------   function PlaceMarker(location) {     var marker = new google.maps.Marker(         {             position: location,             map: gTheMap,             draggable: true         });     marker.addListener('dragend', DragEnd);     return marker; } Bing: // ---- PlaceMarker ------------------------------------   function PlaceMarker(location) {     var marker = new Microsoft.Maps.Pushpin(location,     {         draggable : true     });     Microsoft.Maps.Events.addHandler(marker, 'dragend', DragEnd);     gTheMap.entities.push(marker);     return marker; } Here is the code than runs when the user stops dragging a marker: Google: // ---- DragEnd -------------------------------------------   var gLine = null;   function DragEnd(Event) {     var meters = google.maps.geometry.spherical.computeDistanceBetween(marker1.position, marker2.position);     var yards = meters * 1.0936133;     $("#message").text(yards.toFixed(1) + ' yards');    // draw a line connecting the points     var Endpoints = [marker1.position, marker2.position];       if (gLine == null)     {         gLine = new google.maps.Polyline({             path: Endpoints,             strokeColor: "#FFFF00",             strokeOpacity: 1.0,             strokeWeight: 2,             map: gTheMap         });     }     else        gLine.setPath(Endpoints); } Bing: // ---- DragEnd -------------------------------------------   var gLine = null;   function DragEnd(Args) {    var Distance =  CalculateDistance(marker1._location, marker2._location);      $("#message").text(Distance.toFixed(1) + ' yards');       // draw a line connecting the points    var Endpoints = [marker1._location, marker2._location];           if (gLine == null)    {        gLine = new Microsoft.Maps.Polyline(Endpoints,            {                strokeColor: new Microsoft.Maps.Color(0xFF, 0xFF, 0xFF, 0),  // aRGB                strokeThickness : 2            });          gTheMap.entities.push(gLine);    }    else        gLine.setLocations(Endpoints);  }  Note: I couldn't find a function to calculate the distance between points in the Bing API, so I wrote my own (CalculateDistance). If you want to see the source for it, you can pick it off the web page. Note: I was able to verify the accuracy of the measurements by using the golf hole next to the field. I put a pin/marker on the center of the green, and then by zooming in, I was able to see the 150 markers on the fairway and put the other pin/marker on one of them. Final Notes: All in all, the APIs are very similar. Both made it easy to accomplish a lot with a minimum amount of code. In one aerial view, there are leaves on the tree, in the other, the trees are bare. I don't know which service has the newer data. Here are links to working pages: Bing Map Demo Google Map Demo I hope someone finds this useful. Steve Wellens   CodeProject

• Looking to create website that can have custom GUI and database per user

  - by riley3131

  I have developed an MS Access database for a company to track data in regards to production of a certain commodity. It has many many tables, forms, reports, etc. These were all done as the user requested, and resemble the users previously used system, mostly printed worksheets and excel workbooks. This has created a central location for all information and has allowed the company to compare data in a new way. I am now looking to do this for other companies, but would like to switch it to a web application. Here is my question. What is the best way to create unique solutions for individual companies that can have around 100 users each? I would love to create one site that would serve all parties, but that would ruin the customizable nature of what I am developing. I love the ability to create reports, excel sheets, pdf, graphs, etc with access, but am tired of relying on my customers software, servers, etc. I have some experience with WAMP, but I am far better at VBA. I was okay at PHP, and was getting a grasp on JavaScript a few years back. I am also trying to decide whether to go with WAMP or LAMP, if web is the best choice. Also, should I try set up one site for all users that after log-in goes to company specific pages, or individual sites for each company? Should I host or use a service?

• What are solutions and tradeoffs to maintain search result consistency in a web application

  - by iammichael

  Consider a web application with a custom search function that must display the results in a paged manner (twenty per page with up to hundreds of thousands of total results) and the ability to drill down to individual results that maintain next/previous links to navigate through the results. Re-executing the search on each page request to get the appropriate results for that page of data can be too expensive (up to 15s per search). Also, since the underlying data can change frequently (e.g. addition of new results), re-executing could cause the next/previous functionality to result in inconsistent behavior (e.g. the same results reappearing on a later page after having been viewed on an earlier page). What options exist to ensure the search results can be viewed across multiple pages in a consistent manner, and what tradeoffs does each option have in terms of network, CPU, memory, and storage requirements? EDIT: I thought caching the query search results was an obvious necessity. The question is really asking about where to cache the result set and what tradeoffs might exist to each. For example, storing the ids of the entities in the result set on the client, or storing the IDs of the entities themselves in the users session on the web server, or in a temporary table in the database. I'm not looking specifically for a single solution as different scenarios may result in different approaches (and such a question would be more suited for stackoverflow.com rather than here), but more of a design comparison between the possible approaches.

• Visual Studio 2010 SP1 Beta supports IIS Express

  - by DigiMortal

  Visual Studio 2010 SP1 Beta and ASP.NET MVC 3 RC2 were both announced today. I made a little test on one of my web applications to see how Visual Studio 2010 works with IIS Express. In this posting I will show you how to make your ASP.NET MVC 3 application work with IIS Express. Installing new stuff You can install IIS Express using Web Platform Installer. It is not part of WebMatrix anymore and you can just install IIS Express without WebMatrix. NB! You have to install IIS Express using Web Platform installer because IIS Express is not installed by SP1. After installing Visual Studio 2010 SP1 Beta on my machine (it took a long-long-long time to install) I installed also ASP.NET MVC 3 RC2. If you have Async CTP installed on your machine you have to uninstall it to get ASP.NET MVC 3 RC2 installed and run without problems. Screenshot on right shows what kinf of horrors my old laptop had to survive to get all new stuff installer. Setting IIS Express as server for web application Now, when you right-click on some web project you should see new menu item in context menu – Use IIS Express…. If you click on it you are asked for confirmation and if you say Yes then your web application is reconfigured to use IIS Express. After configuration you will see dialog box like this. And you are done. You can run your application now. Running web application When you run your application it is run on IIS Express. You can see IIS Express icon on taskbar and when you click it you can open IIS Express settings. If you closed your application in browser you can open it again from IIS Express icon. Modifying IIS Express settings for web application You can modify IIS Express settings for your application. Just open your project properties and move to Web tab. IIS and IIS Express are using same settings. The difference is if you make check to Use IIS Express checkbox or not. Switching back to Visual Studio Development Server If you don’t want or you can’t use IIS Express for some reason you can easily switch back to Visual Studio Development Server. Just right-click on your web application project and select Use Visual Studio Development Server from context menu. Conclusion IIS Express is more independent than full version of IIS and it can be also installed and run on machines where are very strict rules (some corporate and academic environments by example). IIS Express was previously part of WebMatrix package but now it is separate product and Visual Studio 2010 has very nice support for it thanks to SP1. You can easily make your web applications use IIS Express and if you want to switch back to development server it is also very easy.

• What PC for programming? [on hold]

  - by James Jeffery

  I'm asking this here because I'm looking for some advice on a PC that will be suitable for my needs. I currently have mac's and have rarely used PC's apart from my Vaio laptop, which is on it's way out. I will be using the PC for C# and .NET development. I mainly develop desktop apps using a PC, but I will be doing some ASP.NET as I'm switching from PHP to ASP. The selection of PC's are on here: http://www.pcworld.co.uk/ I have £500, but if I can not spend all of that I'd be happy. I will be doing nothing on the computer apart from C# development (desktop and ASP). Any help would be much appreciated. My applications are not intensive. They are usually automation software for web scraping and marketing purposes.

  - by nikolaosk

  In this post I would like to talk about LINQ to SQL and transactions.When I have a LINQ to SQL class I always get asked this question, "How does LINQ treat Transactions?". When we use the DeleteOnSubmit() method or the InsertOnSubmit() method, all of those commands at some point are translated into T-SQL commands and then are executed against the database. All of those commands live in transactions and they follow the basic rules of transaction processing. They do succeed together or fail together...(read more)

• Getting a Web Resource Url in non WebForms Applications

  - by Rick Strahl

  WebResources in ASP.NET are pretty useful feature. WebResources are resources that are embedded into a .NET assembly and can be loaded from the assembly via a special resource URL. WebForms includes a method on the ClientScriptManager (Page.ClientScript) and the ScriptManager object to retrieve URLs to these resources. For example you can do: ClientScript.GetWebResourceUrl(typeof(ControlResources), ControlResources.JQUERY_SCRIPT_RESOURCE); GetWebResourceUrl requires a type (which is used for the assembly lookup in which to find the resource) and the resource id to lookup. GetWebResourceUrl() then returns a nasty old long URL like this: WebResource.axd?d=-b6oWzgbpGb8uTaHDrCMv59VSmGhilZP5_T_B8anpGx7X-PmW_1eu1KoHDvox-XHqA1EEb-Tl2YAP3bBeebGN65tv-7-yAimtG4ZnoWH633pExpJor8Qp1aKbk-KQWSoNfRC7rQJHXVP4tC0reYzVw2&t=634533278261362212 While lately excessive resource usage has been frowned upon especially by MVC developers who tend to opt for content distributed as files, I still think that Web Resources have their place even in non-WebForms applications. Also if you have existing assemblies that include resources like scripts and common image links it sure would be nice to access them from non-WebForms pages like MVC views or even in plain old Razor Web Pages. Where's my Page object Dude? Unfortunately natively ASP.NET doesn't have a mechanism for retrieving WebResource Urls outside of the WebForms engine. It's a feature that's specifically baked into WebForms and that relies specifically on the Page HttpHandler implementation. Both Page.ClientScript (obviously) and ScriptManager rely on a hosting Page object in order to work and the various methods off these objects require control instances passed. The reason for this is that the script managers can inject scripts and links into Page content (think RegisterXXXX methods) and for that a Page instance is required. However, for many other methods - like GetWebResourceUrl() - that simply return resources or resource links the Page reference is really irrelevant. While there's a separate ClientScriptManager class, it's marked as sealed and doesn't have any public constructors so you can't create your own instance (without Reflection). Even if it did the internal constructor it does have requires a Page reference. No good… So, can we get access to a WebResourceUrl generically without running in a WebForms Page instance? We just have to create a Page instance ourselves and use it internally. There's nothing intrinsic about the use of the Page class in ClientScript, at least for retrieving resources and resource Urls so it's easy to create an instance of a Page for example in a static method. For our needs of retrieving ResourceUrls or even actually retrieving script resources we can use a canned, non-configured Page instance we create on our own. The following works just fine: public static string GetWebResourceUrl(Type type, string resource ) { Page page = new Page(); return page.ClientScript.GetWebResourceUrl(type, resource); } A slight optimization for this might be to cache the created Page instance. Page tends to be a pretty heavy object to create each time a URL is required so you might want to cache the instance: public class WebUtils { private static Page CachedPage { get { if (_CachedPage == null) _CachedPage = new Page(); return _CachedPage; } } private static Page _CachedPage; public static string GetWebResourceUrl(Type type, string resource) { return CachedPage.ClientScript.GetWebResourceUrl(type, resource); } } You can now use GetWebResourceUrl in a Razor page like this: <!DOCTYPE html> <html <head> <script src="@WebUtils.GetWebResourceUrl(typeof(ControlResources),ControlResources.JQUERY_SCRIPT_RESOURCE)"> </script> </head> <body> <div class="errordisplay"> <img src="@WebUtils.GetWebResourceUrl(typeof(ControlResources),ControlResources.WARNING_ICON_RESOURCE)" /> This is only a Test! </div> </body> </html> And voila - there you have WebResources served from a non-Page based application. WebResources may be a on the way out, but legacy apps have them embedded and for some situations, like fallback scripts and some common image resources I still like to use them. Being able to use them from non-WebForms applications should have been built into the core ASP.NETplatform IMHO, but seeing that it's not this workaround is easy enough to implement.© Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET  MVC   Tweet (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• RequestValidation Changes in ASP.NET 4.0

  - by Rick Strahl

  There’s been a change in the way the ValidateRequest attribute on WebForms works in ASP.NET 4.0. I noticed this today while updating a post on my WebLog all of which contain raw HTML and so all pretty much trigger request validation. I recently upgraded this app from ASP.NET 2.0 to 4.0 and it’s now failing to update posts. At first this was difficult to track down because of custom error handling in my app – the custom error handler traps the exception and logs it with only basic error information so the full detail of the error was initially hidden. After some more experimentation in development mode the error that occurs is the typical ASP.NET validate request error (‘A potentially dangerous Request.Form value was detetected…’) which looks like this in ASP.NET 4.0: At first when I got this I was real perplexed as I didn’t read the entire error message and because my page does have: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="NewEntry.aspx.cs" Inherits="Westwind.WebLog.NewEntry" MasterPageFile="~/App_Templates/Standard/AdminMaster.master" ValidateRequest="false" EnableEventValidation="false" EnableViewState="false" %> WTF? ValidateRequest would seem like it should be enough, but alas in ASP.NET 4.0 apparently that setting alone is no longer enough. Reading the fine print in the error explains that you need to explicitly set the requestValidationMode for the application back to V2.0 in web.config: <httpRuntime executionTimeout="300" requestValidationMode="2.0" /> Kudos for the ASP.NET team for putting up a nice error message that tells me how to fix this problem, but excuse me why the heck would you change this behavior to require an explicit override to an optional and by default disabled page level switch? You’ve just made a relatively simple fix to a solution a nasty morass of hard to discover configuration settings??? The original way this worked was perfectly discoverable via attributes in the page. Now you can set this setting in the page and get completely unexpected behavior and you are required to set what effectively amounts to a backwards compatibility flag in the configuration file. It turns out the real reason for the .config flag is that the request validation behavior has moved from WebForms pipeline down into the entire ASP.NET/IIS request pipeline and is now applied against all requests. Here’s what the breaking changes page from Microsoft says about it: The request validation feature in ASP.NET provides a certain level of default protection against cross-site scripting (XSS) attacks. In previous versions of ASP.NET, request validation was enabled by default. However, it applied only to ASP.NET pages (.aspx files and their class files) and only when those pages were executing. In ASP.NET 4, by default, request validation is enabled for all requests, because it is enabled before the BeginRequest phase of an HTTP request. As a result, request validation applies to requests for all ASP.NET resources, not just .aspx page requests. This includes requests such as Web service calls and custom HTTP handlers. Request validation is also active when custom HTTP modules are reading the contents of an HTTP request. As a result, request validation errors might now occur for requests that previously did not trigger errors. To revert to the behavior of the ASP.NET 2.0 request validation feature, add the following setting in the Web.config file: <httpRuntime requestValidationMode="2.0" /> However, we recommend that you analyze any request validation errors to determine whether existing handlers, modules, or other custom code accesses potentially unsafe HTTP inputs that could be XSS attack vectors. Ok, so ValidateRequest of the form still works as it always has but it’s actually the ASP.NET Event Pipeline, not WebForms that’s throwing the above exception as request validation is applied to every request that hits the pipeline. Creating the runtime override removes the HttpRuntime checking and restores the WebForms only behavior. That fixes my immediate problem but still leaves me wondering especially given the vague wording of the above explanation. One thing that’s missing in the description is above is one important detail: The request validation is applied only to application/x-www-form-urlencoded POST content not to all inbound POST data. When I first read this this freaked me out because it sounds like literally ANY request hitting the pipeline is affected. To make sure this is not really so I created a quick handler: public class Handler1 : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; context.Response.Write("Hello World <hr>" + context.Request.Form.ToString()); } public bool IsReusable { get { return false; } } } and called it with Fiddler by posting some XML to the handler using a default form-urlencoded POST content type: and sure enough – hitting the handler also causes the request validation error and 500 server response. Changing the content type to text/xml effectively fixes the problem however, bypassing the request validation filter so Web Services/AJAX handlers and custom modules/handlers that implement custom protocols aren’t affected as long as they work with special input content types. It also looks that multipart encoding does not trigger event validation of the runtime either so this request also works fine: POST http://rasnote/weblog/handler1.ashx HTTP/1.1 Content-Type: multipart/form-data; boundary=------7cf2a327f01ae User-Agent: West Wind Internet Protocols 5.53 Host: rasnote Content-Length: 40 Pragma: no-cache <xml>asdasd</xml>--------7cf2a327f01ae *That* probably should trigger event validation – since it is a potential HTML form submission, but it doesn’t. New Runtime Feature, Global Scope Only? Ok, so request validation is now a runtime feature but sadly it’s a feature that’s scoped to the ASP.NET Runtime – effective scope to the entire running application/app domain. You can still manually force validation using Request.ValidateInput() which gives you the option to do this in code, but that realistically will only work with the requestValidationMode set to V2.0 as well since the 4.0 mode auto-fires before code ever gets a chance to intercept the call. Given all that, the new setting in ASP.NET 4.0 seems to limit options and makes things more difficult and less flexible. Of course Microsoft gets to say ASP.NET is more secure by default because of it but what good is that if you have to turn off this flag the very first time you need to allow one single request that bypasses request validation??? This is really shortsighted design… <sigh>© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET

• ASP.NET Web API and Simple Value Parameters from POSTed data

  - by Rick Strahl

  In testing out various features of Web API I've found a few oddities in the way that the serialization is handled. These are probably not super common but they may throw you for a loop. Here's what I found. Simple Parameters from Xml or JSON Content Web API makes it very easy to create action methods that accept parameters that are automatically parsed from XML or JSON request bodies. For example, you can send a JavaScript JSON object to the server and Web API happily deserializes it for you. This works just fine:public string ReturnAlbumInfo(Album album) { return album.AlbumName + " (" + album.YearReleased.ToString() + ")"; } However, if you have methods that accept simple parameter types like strings, dates, number etc., those methods don't receive their parameters from XML or JSON body by default and you may end up with failures. Take the following two very simple methods:public string ReturnString(string message) { return message; } public HttpResponseMessage ReturnDateTime(DateTime time) { return Request.CreateResponse<DateTime>(HttpStatusCode.OK, time); } The first one accepts a string and if called with a JSON string from the client like this:var client = new HttpClient(); var result = client.PostAsJsonAsync<string>(http://rasxps/AspNetWebApi/albums/rpc/ReturnString, "Hello World").Result; which results in a trace like this: POST http://rasxps/AspNetWebApi/albums/rpc/ReturnString HTTP/1.1Content-Type: application/json; charset=utf-8Host: rasxpsContent-Length: 13Expect: 100-continueConnection: Keep-Alive "Hello World" produces… wait for it: null. Sending a date in the same fashion:var client = new HttpClient(); var result = client.PostAsJsonAsync<DateTime>(http://rasxps/AspNetWebApi/albums/rpc/ReturnDateTime, new DateTime(2012, 1, 1)).Result; results in this trace: POST http://rasxps/AspNetWebApi/albums/rpc/ReturnDateTime HTTP/1.1Content-Type: application/json; charset=utf-8Host: rasxpsContent-Length: 30Expect: 100-continueConnection: Keep-Alive "\/Date(1325412000000-1000)\/" (yes still the ugly MS AJAX date, yuk! This will supposedly change by RTM with Json.net used for client serialization) produces an error response: The parameters dictionary contains a null entry for parameter 'time' of non-nullable type 'System.DateTime' for method 'System.Net.Http.HttpResponseMessage ReturnDateTime(System.DateTime)' in 'AspNetWebApi.Controllers.AlbumApiController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Basically any simple parameters are not parsed properly resulting in null being sent to the method. For the string the call doesn't fail, but for the non-nullable date it produces an error because the method can't handle a null value. This behavior is a bit unexpected to say the least, but there's a simple solution to make this work using an explicit [FromBody] attribute:public string ReturnString([FromBody] string message) andpublic HttpResponseMessage ReturnDateTime([FromBody] DateTime time) which explicitly instructs Web API to read the value from the body. UrlEncoded Form Variable Parsing Another similar issue I ran into is with POST Form Variable binding. Web API can retrieve parameters from the QueryString and Route Values but it doesn't explicitly map parameters from POST values either. Taking our same ReturnString function from earlier and posting a message POST variable like this:var formVars = new Dictionary<string,string>(); formVars.Add("message", "Some Value"); var content = new FormUrlEncodedContent(formVars); var client = new HttpClient(); var result = client.PostAsync(http://rasxps/AspNetWebApi/albums/rpc/ReturnString, content).Result; which produces this trace: POST http://rasxps/AspNetWebApi/albums/rpc/ReturnString HTTP/1.1Content-Type: application/x-www-form-urlencodedHost: rasxpsContent-Length: 18Expect: 100-continue message=Some+Value When calling ReturnString:public string ReturnString(string message) { return message; } unfortunately it does not map the message value to the message parameter. This sort of mapping unfortunately is not available in Web API. Web API does support binding to form variables but only as part of model binding, which binds object properties to the POST variables. Sending the same message as in the previous example you can use the following code to pick up POST variable data:public string ReturnMessageModel(MessageModel model) { return model.Message; } public class MessageModel { public string Message { get; set; }} Note that the model is bound and the message form variable is mapped to the Message property as would other variables to properties if there were more. This works but it's not very dynamic. There's no real easy way to retrieve form variables (or query string values for that matter) in Web API's Request object as far as I can discern. Well only if you consider this easy:public string ReturnString() { var formData = Request.Content.ReadAsAsync<FormDataCollection>().Result; return formData.Get("message"); } Oddly FormDataCollection does not allow for indexers to work so you have to use the .Get() method which is rather odd. If you're running under IIS/Cassini you can always resort to the old and trusty HttpContext access for request data:public string ReturnString() { return HttpContext.Current.Request.Form["message"]; } which works fine and is easier. It's kind of a bummer that HttpRequestMessage doesn't expose some sort of raw Request object that has access to dynamic data - given that it's meant to serve as a generic REST/HTTP API that seems like a crucial missing piece. I don't see any way to read query string values either. To me personally HttpContext works, since I don't see myself using self-hosted code much.© Rick Strahl, West Wind Technologies, 2005-2012Posted in Web Api   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();
