  • thick client migration to web based application

    - by user1151597
    This query is related to application design the technology that I should consider during migration. The Scenario: I have a C#.net Winform application which communicates with a device. One of the main feature of this application is monitoring cyclic data(rate 200ms) sent from the device to the application. The request to start the cyclic data is sent only once in the beginning and then the application starts receiving data from the device until it sends a stop request. Now this same application needs to be deployed over the web in a intranet. The application is composed of a business logic layer and a communication layer which communicates with the device through UDP ports. I am trying to look at a solution which will allow me to have a single instance of the application on the server so that the device thinks that it is connected as usual and then from the business logic layer I can manage the clients. I want to reuse the code of the business layer and the communication layer as much as possible. Please let me know if webserives/WCF/ etc what i should consider to design the migration. Thanks in advance.

  • Suggestion for setting web application parameters

    - by user40730
    I'm creating a web application on GWT. I'm using MVP pattern with activities and places. I have a xml config file containing some parameters to be used by the application. Content of this xml file is sent to the client using HttpRequest; I'm using a singleton class to hold the information from the xml file. Right now, the application is getting the data when the user starts the application in the home page, that is working well. Now, since I'm using activities and places, a user can bookmark a page and starts the application in any other page (Place). And here comes the problem: Since I'm using some of the information from the xml file to set some ui widgets, I have to check if the xml config file was read and the application already has the parameters (I do this by checking the singleton class). But the xml file is read by using an HttpRequest, so I got errors 'cause the application needs some parameters to initialize some ui widgets, but these parameters aren't ready on time. I was thinking on using an synchronous request to fix the problem, but it seems complicated and not recommendable to do that. So, I'd like to hear some other suggestions. Thanks.

  • Redirecting 2 or more domains to same hosting server

    - by mtk
    I have domains A.com, A.co.in and A.in Purchased from site X. I have a hosting space/account purchased from site Y, which has provided me with 2 DNS entries that is to be replaced in the account at the site from where I purchase the domains. I have successfully changed the DNS entries of A.com to these 2 DNS entries and I am able to see my index.html page when I hit A.com. Problem On similar lines, I have changed the DNS entries to the same entries for A.co.in and A.in, but on hitting those sites in browser gives me no response and browser specific page of 'Site not found' is been seen. Please let me know, how to set this, so that when I hit any of the domain, the web-site is rendered from the hosting server? What am I doing wrong here? Note It has been more than 3 days after changing the DNS entries, so I don't think so this is a problem of DNS propagation, which I heard from some people. Please provide some detail explanation, as I am very very new to this. This is my first hosting ;) -Thanks

  • RESTful applications logic and cross resource operations

    - by Gaz_Edge
    I have an RESTful api that allows my users to receive enquiries about their business e.g. 'I would like to book service x on date y. Is this available?'. The api saves this information as a resource to the following URI users/{userId}/enquiries/{enquiryId} The information shown when this resource is retrieved are the standard sort of things you'd expect from an enquiry - email, first_name, last_name, address, message The api also allows customers to be created for a user. The customer has a login and password and also a profile. The following URIs expose these two resources PUT users/{userId}/customers/{customerId} PUT users/{userId}/customers/{customerId}/profile The problem I am having is that I would like to have the ability to allow users to create a customer from an enquiry. For example, the user is able to offer their service on the date requested and will then want to setup a customer with login details etc to allow them to manage the rest of the process. The obvious answer would be to use a URI like users/{userId}/enquiries/{enquiryId}/convert-to-client The problem with this is is that it somewhat goes against a lot of what I've been reading about how to implement REST (specifically from the book Restful Web Services which suggests that URIs should point to resources not operations on resources). The other option would be to get the client application (i.e. the code that calls the api) to handle some of this application logic. This doesn't quite feel right to me. I have implemented in my design that the client app is fairly dumb. It knows just enough to display the results from the API, and does not contain any application logic. Would be great to hear what others views are on the best way of setting this up Am I wrong to have no application logic in the client app? How would I perform this operation purely in the REST api?

  • Skip CodedUI Tests, use Selenium for Web Automation

    - by Aligned
    Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/10/31/skip-codedui-tests-use-selenium-for-web-automation.aspxI recently joined a team that was using Agile Methodologies to create a new product. They have a working beta product after 10 or so 2 week sprints and already had UI’s that had changed several times as they went through iterations of their UI. As a result, the QA team was falling behind with automated tests and I was tasked to help them catch up and expand their tests. The project is a website. I heard many complaints about how hard it is to work with CodedUI (writing our own code, not relying on the recorder as we wanted re-usable and more maintainable code) then it took me 4+ hours to fix one issue. It was hard to traverse the key and debugging the objects with breakpoints… I said out loud “there has to be a better way or a framework the uses jQuery to run through the tests.” Plus it seemed really slow (wait… finding the object … wait… start putting in text…). Plus some tests would randomly fail on the test agents (using the test settings and an automated build, they are run on VMs using Microsoft test agents). Enough complaining. Selenium to the rescue (mostly). The lead QA guy decided to try it out and we haven’t turned back. We are now running tests in Chrome and Firefox and they run a lot faster. We had IE running to, but some of the tests were running fine locally, but hanging on the test agents. I’ll add some hints and lessons learned in a later post.

  • Is there a future for AAA game development in C#? [closed]

    - by kasperov
    When XNA was released in 2006, I was happy and started doing indie attempts. After 3 years or so, there were lots of forum discussions on prospects of AAA game development in C#, and how a high performance vedio game can easily be programmed in C#. Suddenly after 2-3 more years, these discussions have died down and everybody seems like recommending native C++... What programming language should I practice on for long term? Should I stick with C# or do an extra effort for C++? Will AAA game companies adopt C# as a replacement to C++? Note : I aim to work at a AAA game company.

  • Using a random string to authenticate HMAC?

    - by mrwooster
    I am designing a simple webservice and want to use HMAC for authentication to the service. For the purpose of this question we have: a web service at example.com a secret key shared between a user and the server [K] a consumer ID which is known to the user and the server (but is not necessarily secret) [D] a message which we wish to send to the server [M] The standard HMAC implementation would involve using the secret key [K] and the message [M] to create the hash [H], but I am running into issues with this. The message [M] can be quite long and tends to be read from a file. I have found its very difficult to produce a correct hash consistently across multiple operating systems and programming languages because of hidden characters which make it into various file formats. This is of course bad implementation on the client side (100%), but I would like this webservice to be easily accessible and not have trouble with different file formats. I was thinking of an alternative, which would allow the use a short (5-10 char) random string [R] rather than the message for autentication, e.g. H = HMAC(K,R) The user then passes the random string to the server and the server checks the HMAC server side (using random string + shared secret). As far as I can see, this produces the following issues: There is no message integrity - this is ok message integrity is not important for this service A user could re-use the hash with a different message - I can see 2 ways around this Combine the random string with a timestamp so the hash is only valid for a set period of time Only allow each random string to be used once Since the client is in control of the random string, it is easier to look for collisions I should point out that the principle reason for authentication is to implement rate limiting on the API service. There is zero need for message integrity, and its not a big deal if someone can forge a single request (but it is if they can forge a very large number very quickly). I know that the correct answer is to make sure the message [M] is the same on all platforms/languages before hashing it. But, taking that out of the equation, is the above proposal an acceptable 2nd best?

  • I am new to game development, what do I need to know? [closed]

    - by farmdve
    I am unsure if this question is a duplicate, I hope it isn't. Are there any resources on the terminology when doing game development? Because, even if you tell me to learn some graphics API, how would I understand the things it does, if I am not well into the terminology(voxel,mesh,polygon,shading). What about the math that is involved in the game(geometry) or the concept of the gravity,collision detection in the game and their respective maths? I am very bad at math, never was good, because I have ADHD, but I won't give up just yet. I look at a game, and I see "textures", but how am I walking on them, how do they take substance so I don't fall off of them? And depth? This is what I need information about, not just a link to a library like SDL(which I have compiled under MinGW and MinGW-W64) and tell me to learn it and the cliché answer "start simple/small". I hope the question(s) are not too vague.

  • What is a good university for computer science and game development?

    - by DukeYore
    I am starting my computer science degree at a local community college in programming using C++. However, I will be transferring to a 4-year university. Does anyone have any insight on university programs? I know Cal State Fullerton has a degree with a minor in Game Development. however, is that as important as getting a degree from a really great school? If I could shoot for something like Cal Poly would that be better? Or even Stanford or SF State being so close to so many gaming companies up there in the Bay area?

  • Which would a game development company prefer; UDK experience or C++ game projects?

    - by momboco
    Which would a game development company prefer? A developer with experience in UDK engine ? or, a developer with projects made entirely in c++ with a graphics engine like Ogre3D? I think that a coder can demonstrate better his abilities with games made in c++, because it requires a knowledge deeper in many fields. However, currently there is a lot of companies that develop his games with UDK. Now I don't know if is better specialize in a game engine like UDK.

  • Amazon EC2 vs Dedicated server at Hetzner, what's the use for EC2?

    - by C-Blu
    After searching the web I still can't find the reason to use EC2. What's the point to scale EC2? If you expect a huge burst in traffic, they say. OK, but what if you already have a couple of sites with good traffic, and for example medium reserved EC2 instance is not enough. You are paying $36.60(medium reserved for 1year) in EU(Ireland) + traffic + optional expenses for databases and S3 if you use them. Of course as some point when you are under $56.6-$66.1 you can optimize your hosting costs with Amazon EC2. But when you get at some point if purchase EX4 server from Hetzner, it will surpass your perfomance needs for a long time, before you get a massive traffic. (I am wrong?) CPU: i7-2600 Quadcore (3.4-3.8 Ghz) RAM: 16 GB HDD: 2x3 TB SATA (6 Gbit/s) - I think that disc performance of a dedicated is better then of Amazon EBS Traffic: 10 TiB in month included. This is what you get from Hetzner for $56(- 19% VAT) or $66 for EU residents. Please, tell me what's the reason to use Amazon? Which load won't a server from Hetzner take, but Amazon Auto Scaling will? The maintenance of dedicated vs EC2 is still the same? Or hardware failure at Amazon, won't ruin your EBS storage? I'm still not at the level when I need expensive hosting, but want to know beforehand, just to be sure if Amazon infrastructure is better then pure performance of Hetzner's hardware.

  • Motivation for service layer (instead of just copying dlls)?

    - by BornToCode
    I'm creating an application which has 2 different UIs so I'm making it with a service layer which I understood is appropriate for such case. However I found myself just creating web methods for every single method I have in the BL layer, so the services basically built from methods that looks like this: return customers_bl.Get_Customer_Prices(customer_id); I understood that a main point of the service layer is to prevent duplication of code so I asked myself - well, why not just import the BL.dll (and the DAL.dll) to the other UI, and whenever making a change re-copy the dll files, it might not be so 'neat', but is the all purpose of the service layer to prevent this? {I know something is wrong in my approach, I'm probably missing the importance of service layer, I'd like to get more motivation to create another layer, especially because as it is I found that many of my BL functions ALREADY looks like: return customers_dal.Get_Customer_Prices(cust_id) which led me to ask: was it really necessary to create the BL just because on several functions I actually have LOGIC inside the BL?} so I'm looking for more motivation to creating ONE MORE layer, I'm sure it's not just to make it more convenient that I won't have to re-copy the dlls on changes? Am I grasping it wrong? Any simple guidelines on how to design service layer (corresponding to all the BL layer functions or not? any simple example?) any enlightenment on the subject?

  • Standard/Compliance for web programming?

    - by MarkusK
    I am working with developers right now that write code the way they want and when i tell them to do it other way they respond that its just matter of preference how to do it and they have their way and i have mine. I am not talking about the formatting of code, but rather of way site is organized in classes and the way the utilize them. and the way they create functions and process forms etc. Their coding does not match my standards, but again they argue that its matter of preference and as long as goal achieved the can be different way's to do it. I agree but their way is proven to have bugs and we spend a lot of time going back and forth with them to fix all problems security or functionality, yet they still write same code no matter how many times i asked them to stop doing certain things. Now i am ready to dismiss them but friend of mine told me that he has same exact problem with freelance developers he work with. So i don't want to trade one bad apple for another. Question is is there some world wide (or at least europe and usa) accepted standard or compliance on how write secure web based applications. What application architecture should be for maintainable application. Is there are some general standard that can be used for any language ruby php or java govern security and functionality and quality of code? Or at least for PHP and MySQL i use for my website. So i can make them follow this strict standard and stop making excuses.

  • Scala - learning by doing

    - by wrecked
    coming from the PHP-framework symfony (with Apache/MySQL) I would like to dive into the Scala programming language. I already followed a few tutorials and had a look at Lift and Play. Java isn't a stranger to me either. However the past showed that it's easiest to learn things by just doing them. Currently we have a little - mostly ajax-driven - application build on symfony at my company. My idea is to just build a little project similar to this one which might gets into production in the future. The app should feature: High scalability and performance a backend-server web-interface and a GUI-client There are plenty of questions arising when I think of this. First of all: Whats the best way to accomplish a easy to maintain, structured base for it? Would it be best to establish a socket based communication between pure-scala server/client and accessing that data via Lift or is building a Lift-app serving as a server and connecting the gui-client (via REST?) the better way? Furthermore I wounder which database to choose. I'm familiar with (My)SQL but feel like a fool beeing confronted with all these things like NoSQL, MongoDB and more. Thanks in advance!

  • OOP Structure for web application

    - by Query
    Ok so I have a website in which users complete tasks to earn points. When they earn enough points, they rise in rank. The site from my understanding is very basic and only executes one query or two queries at most a page. There is a user table, a support ticket table, and an orders table. All of these contain a relational row for username. Our class was familiarized with OOP back in highschool with Java but that was for video games and I could grasp the concept on why you would need a class player and class enemy. However I don't understand it's web application. At least not in my situation. I understand the user class might contain stuff like: getUsername getPoints getEmail setEmail addPoints (does this belong here? OR only things the user can manipulate should be here?) etc.. But I'm at a loss with everything else such as user registration. Can you help give me a wire framework that I could wrap my head around? Pointing me to a good eBook would help greatly

  • which technology or strategy a new / inexperienced freelancer should use to earn profit? [closed]

    this question has re-posted by me in the following group if you find suitable to answer this question then please click on the link attached here or copy paste this in your browser.. http://answers.onstartups.com/questions/32767/which-technology-or-strategy-a-new-inexperienced-freelancer-should-use-to-earn Well it is my very first Question in this section and i really don't know whether my query relate to this section or not. anyway i have some awkward query. (however, it is like a bit story but i guess it is necessary to know some background knowledge of me.) Actually I m fresh recent grad who has just started his freelancing work. In due course i have got a project to develop website for a middle scale business (travel agent). As I don't trust on my client whether he will pay to me in full or not after the completion of website, i want to use cheaper and efficient technology so that how much he would pay I could got at least few units of % of profit. As i have learnt ASP.NET and when I inquired about the expense in Hosting of my website i got the recommendation to develop my web app using the combination PHP and MYSQL instead the asp.net + ms sql. And the problem is I don't know PHP. should I learn PHP and or work in what i m comfortable with and should try to cover whole deserved money. (as it is my first project so i m also advised that i may got some loss in starting but contrary to this i don't want to go in loss and want to earn appropriate profit)

    I am interested in developing some 2d game since I have graduated and got some time to spare. I am looking for some advices where to start and with what. My main target platforms are Mac and Windows (later porting/rewriting/modifying for iOS, Android or WP7 is considerable). I need some advices about language I should choose, frameworks, engines and this kind of stuff. I gotta start somehow, but first of all I need to know how. Choosing good language with great framework/engine is key to ongoing successful game development I think.

  • PHP and Ruby: how to leverage both? and, is it worth it?

    - by dukeofgaming
    As you might have noticed from the title, this is not a "PHP or Ruby", or a "PHP vs. Ruby" question. This is a question on how to leverage PHP + Ruby in the same business. I myself am a PHP developer, I love the language because of its convenience and I specially love the ecosystem of resources that surround it: Joomla, Drupal, Wordpress, Symfony2, Doctrine2, etc. However, the language itself can be a little disappointing sometimes. OTOH, Ruby looks like a very beautiful language and —from studying it superficially in several aspects— I could say it is leaner than Python as a language per se. However, from what I've seen there is pretty much only RoR making noise, and I don't like RoR so much (mainly because its model layer). As Co-CEO and CTO at my company I'm trying to think outside of the box since I want to start to focus on the human side of technology and see if its sane to use both PHP and Ruby. Here are some random thoughts: Ruby folk seem to be generally better suited programmers than PHP folk (in terms of averages), I know the previous statement is somewhat baloney because very good and well architected PHP can be written, but I'd say the Ruby programmer culture is better than PHP's. The thing about Ruby is that it seems better suited for rapid development, I don't really know if this is only the case for RoR, but I do know that there are certain practices (perhaps not so good) like monkey patching that let business needs be satified quicker. From a marketing point of view (yep, sometimes you need to leverage the marketing BS for the sake of your company) Ruby seems better while PHP carries some stigmas. PHP 5.4 is bringing traits, and that is better/cleaner than mixins. That could really make PHP as lean as Ruby —or more— for certain stuff. Now, concretely, my questions: Would a PHP programmer want to learn Ruby?, I know I do, but conversely, would a Ruby programmer want to learn PHP?. What kinds of projects or situations would be better suited for Ruby that are not suited for PHP?. What is the actual ecosystem of Ruby?, aside from RoR, I have not seen other hyped technologies/frameworks (I've seen RSpec, but I confess being a total noob on what BDD really consists of and its implications). Supposing there are a certain type of projects ideal for Ruby, would there be a moment that its better to move it to PHP?. I know PHP can handle lots of stuff, but I've read that Ruby has its limitations when scaling (or is that RoR?, or is that baloney for both?). Finally and most importantly, would it be sane to maintain projects in two languages?, or is that just stupid. As I said, it looks like Ruby is leaner on the short term and that can make a project happen and succeed, but I'm not so sure about that on the long run. I'm looking for insights mainly from people that know well the strengths and weaknesses of the languages —preferably both of them— and Ruby's ecosystem in real practice, meaning: frameworks and applications like the ones I quoted from PHP's ecosystem. Best regards and thanks for your time.

  • 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 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: 'XXXXXXXXXXXXXXXXXXX',                 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

  • WCF WS-Security and WSE Nonce Authentication

    - by Rick Strahl
    WCF makes it fairly easy to access WS-* Web Services, except when you run into a service format that it doesn't support. Even then WCF provides a huge amount of flexibility to make the service clients work, however finding the proper interfaces to make that happen is not easy to discover and for the most part undocumented unless you're lucky enough to run into a blog, forum or StackOverflow post on the matter. This is definitely true for the Password Nonce as part of the WS-Security/WSE protocol, which is not natively supported in WCF. Specifically I had a need to create a WCF message on the client that includes a WS-Security header that looks like this from their spec document:<soapenv:Header> <wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <wsse:UsernameToken wsu:Id="UsernameToken-8" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <wsse:Username>TeStUsErNaMe1</wsse:Username> <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >TeStPaSsWoRd1</wsse:Password> <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" >f8nUe3YupTU5ISdCy3X9Gg==</wsse:Nonce> <wsu:Created>2011-05-04T19:01:40.981Z</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soapenv:Header> Specifically, the Nonce and Created keys are what WCF doesn't create or have a built in formatting for. Why is there a nonce? My first thought here was WTF? The username and password are there in clear text, what does the Nonce accomplish? The Nonce and created keys are are part of WSE Security specification and are meant to allow the server to detect and prevent replay attacks. The hashed nonce should be unique per request which the server can store and check for before running another request thus ensuring that a request is not replayed with exactly the same values. Basic ServiceUtl Import - not much Luck The first thing I did when I imported this service with a service reference was to simply import it as a Service Reference. The Add Service Reference import automatically detects that WS-Security is required and appropariately adds the WS-Security to the basicHttpBinding in the config file:<?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="RealTimeOnlineSoapBinding"> <security mode="Transport" /> </binding> <binding name="RealTimeOnlineSoapBinding1" /> </basicHttpBinding> </bindings> <client> <endpoint address="https://notarealurl.com:443/services/RealTimeOnline" binding="basicHttpBinding" bindingConfiguration="RealTimeOnlineSoapBinding" contract="RealTimeOnline.RealTimeOnline" name="RealTimeOnline" /> </client> </system.serviceModel> </configuration> If if I run this as is using code like this:var client = new RealTimeOnlineClient(); client.ClientCredentials.UserName.UserName = "TheUsername"; client.ClientCredentials.UserName.Password = "ThePassword"; … I get nothing in terms of WS-Security headers. The request is sent, but the the binding expects transport level security to be applied, rather than message level security. To fix this so that a WS-Security message header is sent the security mode can be changed to: <security mode="TransportWithMessageCredential" /> Now if I re-run I at least get a WS-Security header which looks like this:<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <u:Timestamp u:Id="_0"> <u:Created>2012-11-24T02:55:18.011Z</u:Created> <u:Expires>2012-11-24T03:00:18.011Z</u:Expires> </u:Timestamp> <o:UsernameToken u:Id="uuid-18c215d4-1106-40a5-8dd1-c81fdddf19d3-1"> <o:Username>TheUserName</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >ThePassword</o:Password> </o:UsernameToken> </o:Security> </s:Header> Closer! Now the WS-Security header is there along with a timestamp field (which might not be accepted by some WS-Security expecting services), but there's no Nonce or created timestamp as required by my original service. Using a CustomBinding instead My next try was to go with a CustomBinding instead of basicHttpBinding as it allows a bit more control over the protocol and transport configurations for the binding. Specifically I can explicitly specify the message protocol(s) used. Using configuration file settings here's what the config file looks like:<?xml version="1.0"?> <configuration> <system.serviceModel> <bindings> <customBinding> <binding name="CustomSoapBinding"> <security includeTimestamp="false" authenticationMode="UserNameOverTransport" defaultAlgorithmSuite="Basic256" requireDerivedKeys="false" messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10"> </security> <textMessageEncoding messageVersion="Soap11"></textMessageEncoding> <httpsTransport maxReceivedMessageSize="2000000000"/> </binding> </customBinding> </bindings> <client> <endpoint address="https://notrealurl.com:443/services/RealTimeOnline" binding="customBinding" bindingConfiguration="CustomSoapBinding" contract="RealTimeOnline.RealTimeOnline" name="RealTimeOnline" /> </client> </system.serviceModel> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> </startup> </configuration> This ends up creating a cleaner header that's missing the timestamp field which can cause some services problems. The WS-Security header output generated with the above looks like this:<s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <o:UsernameToken u:Id="uuid-291622ca-4c11-460f-9886-ac1c78813b24-1"> <o:Username>TheUsername</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >ThePassword</o:Password> </o:UsernameToken> </o:Security> </s:Header> This is closer as it includes only the username and password. The key here is the protocol for WS-Security:messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10" which explicitly specifies the protocol version. There are several variants of this specification but none of them seem to support the nonce unfortunately. This protocol does allow for optional omission of the Nonce and created timestamp provided (which effectively makes those keys optional). With some services I tried that requested a Nonce just using this protocol actually worked where the default basicHttpBinding failed to connect, so this is a possible solution for access to some services. Unfortunately for my target service that was not an option. The nonce has to be there. Creating Custom ClientCredentials As it turns out WCF doesn't have support for the Digest Nonce as part of WS-Security, and so as far as I can tell there's no way to do it just with configuration settings. I did a bunch of research on this trying to find workarounds for this, and I did find a couple of entries on StackOverflow as well as on the MSDN forums. However, none of these are particularily clear and I ended up using bits and pieces of several of them to arrive at a working solution in the end. http://stackoverflow.com/questions/896901/wcf-adding-nonce-to-usernametoken http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/4df3354f-0627-42d9-b5fb-6e880b60f8ee The latter forum message is the more useful of the two (the last message on the thread in particular) and it has most of the information required to make this work. But it took some experimentation for me to get this right so I'll recount the process here maybe a bit more comprehensively. In order for this to work a number of classes have to be overridden: ClientCredentials ClientCredentialsSecurityTokenManager WSSecurityTokenizer The idea is that we need to create a custom ClientCredential class to hold the custom properties so they can be set from the UI or via configuration settings. The TokenManager and Tokenizer are mainly required to allow the custom credentials class to flow through the WCF pipeline and eventually provide custom serialization. Here are the three classes required and their full implementations:public class CustomCredentials : ClientCredentials { public CustomCredentials() { } protected CustomCredentials(CustomCredentials cc) : base(cc) { } public override System.IdentityModel.Selectors.SecurityTokenManager CreateSecurityTokenManager() { return new CustomSecurityTokenManager(this); } protected override ClientCredentials CloneCore() { return new CustomCredentials(this); } } public class CustomSecurityTokenManager : ClientCredentialsSecurityTokenManager { public CustomSecurityTokenManager(CustomCredentials cred) : base(cred) { } public override System.IdentityModel.Selectors.SecurityTokenSerializer CreateSecurityTokenSerializer(System.IdentityModel.Selectors.SecurityTokenVersion version) { return new CustomTokenSerializer(System.ServiceModel.Security.SecurityVersion.WSSecurity11); } } public class CustomTokenSerializer : WSSecurityTokenSerializer { public CustomTokenSerializer(SecurityVersion sv) : base(sv) { } protected override void WriteTokenCore(System.Xml.XmlWriter writer, System.IdentityModel.Tokens.SecurityToken token) { UserNameSecurityToken userToken = token as UserNameSecurityToken; string tokennamespace = "o"; DateTime created = DateTime.Now; string createdStr = created.ToString("yyyy-MM-ddThh:mm:ss.fffZ"); // unique Nonce value - encode with SHA-1 for 'randomness' // in theory the nonce could just be the GUID by itself string phrase = Guid.NewGuid().ToString(); var nonce = GetSHA1String(phrase); // in this case password is plain text // for digest mode password needs to be encoded as: // PasswordAsDigest = Base64(SHA-1(Nonce + Created + Password)) // and profile needs to change to //string password = GetSHA1String(nonce + createdStr + userToken.Password); string password = userToken.Password; writer.WriteRaw(string.Format( "<{0}:UsernameToken u:Id=\"" + token.Id + "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" + "<{0}:Username>" + userToken.UserName + "</{0}:Username>" + "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText\">" + password + "</{0}:Password>" + "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" + nonce + "</{0}:Nonce>" + "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace)); } protected string GetSHA1String(string phrase) { SHA1CryptoServiceProvider sha1Hasher = new SHA1CryptoServiceProvider(); byte[] hashedDataBytes = sha1Hasher.ComputeHash(Encoding.UTF8.GetBytes(phrase)); return Convert.ToBase64String(hashedDataBytes); } } Realistically only the CustomTokenSerializer has any significant code in. The code there deals with actually serializing the custom credentials using low level XML semantics by writing output into an XML writer. I can't take credit for this code - most of the code comes from the MSDN forum post mentioned earlier - I made a few adjustments to simplify the nonce generation and also added some notes to allow for PasswordDigest generation. Per spec the nonce is nothing more than a unique value that's supposed to be 'random'. I'm thinking that this value can be any string that's unique and a GUID on its own probably would have sufficed. Comments on other posts that GUIDs can be potentially guessed are highly exaggerated to say the least IMHO. To satisfy even that aspect though I added the SHA1 encryption and binary decoding to give a more random value that would be impossible to 'guess'. The original example from the forum post used another level of encoding and decoding to string in between - but that really didn't accomplish anything but extra overhead. The header output generated from this looks like this:<s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <o:UsernameToken u:Id="uuid-f43d8b0d-0ebb-482e-998d-f544401a3c91-1" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <o:Username>TheUsername</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">ThePassword</o:Password> <o:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" >PjVE24TC6HtdAnsf3U9c5WMsECY=</o:Nonce> <u:Created>2012-11-23T07:10:04.670Z</u:Created> </o:UsernameToken> </o:Security> </s:Header> which is exactly as it should be. Password Digest? In my case the password is passed in plain text over an SSL connection, so there's no digest required so I was done with the code above. Since I don't have a service handy that requires a password digest,  I had no way of testing the code for the digest implementation, but here is how this is likely to work. If you need to pass a digest encoded password things are a little bit trickier. The password type namespace needs to change to: http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#Digest and then the password value needs to be encoded. The format for password digest encoding is this: Base64(SHA-1(Nonce + Created + Password)) and it can be handled in the code above with this code (that's commented in the snippet above): string password = GetSHA1String(nonce + createdStr + userToken.Password); The entire WriteTokenCore method for digest code looks like this:protected override void WriteTokenCore(System.Xml.XmlWriter writer, System.IdentityModel.Tokens.SecurityToken token) { UserNameSecurityToken userToken = token as UserNameSecurityToken; string tokennamespace = "o"; DateTime created = DateTime.Now; string createdStr = created.ToString("yyyy-MM-ddThh:mm:ss.fffZ"); // unique Nonce value - encode with SHA-1 for 'randomness' // in theory the nonce could just be the GUID by itself string phrase = Guid.NewGuid().ToString(); var nonce = GetSHA1String(phrase); string password = GetSHA1String(nonce + createdStr + userToken.Password); writer.WriteRaw(string.Format( "<{0}:UsernameToken u:Id=\"" + token.Id + "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" + "<{0}:Username>" + userToken.UserName + "</{0}:Username>" + "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#Digest\">" + password + "</{0}:Password>" + "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" + nonce + "</{0}:Nonce>" + "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace)); } I had no service to connect to to try out Digest auth - if you end up needing it and get it to work please drop a comment… How to use the custom Credentials The easiest way to use the custom credentials is to create the client in code. Here's a factory method I use to create an instance of my service client:  public static RealTimeOnlineClient CreateRealTimeOnlineProxy(string url, string username, string password) { if (string.IsNullOrEmpty(url)) url = "https://notrealurl.com:443/cows/services/RealTimeOnline"; CustomBinding binding = new CustomBinding(); var security = TransportSecurityBindingElement.CreateUserNameOverTransportBindingElement(); security.IncludeTimestamp = false; security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256; security.MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10; var encoding = new TextMessageEncodingBindingElement(); encoding.MessageVersion = MessageVersion.Soap11; var transport = new HttpsTransportBindingElement(); transport.MaxReceivedMessageSize = 20000000; // 20 megs binding.Elements.Add(security); binding.Elements.Add(encoding); binding.Elements.Add(transport); RealTimeOnlineClient client = new RealTimeOnlineClient(binding, new EndpointAddress(url)); // to use full client credential with Nonce uncomment this code: // it looks like this might not be required - the service seems to work without it client.ChannelFactory.Endpoint.Behaviors.Remove<System.ServiceModel.Description.ClientCredentials>(); client.ChannelFactory.Endpoint.Behaviors.Add(new CustomCredentials()); client.ClientCredentials.UserName.UserName = username; client.ClientCredentials.UserName.Password = password; return client; } This returns a service client that's ready to call other service methods. The key item in this code is the ChannelFactory endpoint behavior modification that that first removes the original ClientCredentials and then adds the new one. The ClientCredentials property on the client is read only and this is the way it has to be added.   Summary It's a bummer that WCF doesn't suport WSE Security authentication with nonce values out of the box. From reading the comments in posts/articles while I was trying to find a solution, I found that this feature was omitted by design as this protocol is considered unsecure. While I agree that plain text passwords are rarely a good idea even if they go over secured SSL connection as WSE Security does, there are unfortunately quite a few services (mosly Java services I suspect) that use this protocol. I've run into this twice now and trying to find a solution online I can see that this is not an isolated problem - many others seem to have struggled with this. It seems there are about a dozen questions about this on StackOverflow all with varying incomplete answers. Hopefully this post provides a little more coherent content in one place. Again I marvel at WCF and its breadth of support for protocol features it has in a single tool. And even when it can't handle something there are ways to get it working via extensibility. But at the same time I marvel at how freaking difficult it is to arrive at these solutions. I mean there's no way I could have ever figured this out on my own. It takes somebody working on the WCF team or at least being very, very intricately involved in the innards of WCF to figure out the interconnection of the various objects to do this from scratch. Luckily this is an older problem that has been discussed extensively online and I was able to cobble together a solution from the online content. I'm glad it worked out that way, but it feels dirty and incomplete in that there's a whole learning path that was omitted to get here… Man am I glad I'm not dealing with SOAP services much anymore. REST service security - even when using some sort of federation is a piece of cake by comparison :-) I'm sure once standards bodies gets involved we'll be right back in security standard hell…© Rick Strahl, West Wind Technologies, 2005-2012Posted in WCF  Web Services   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); })();
