  • Organazing ASP.Net Single Page Application with Nancy

    - by OnesimusUnbound
    As a personal project, I'm creating a single page, asp.net web application using Nancy to provide RESTful services to the single page. Due to the complexity of the single page, particularly the JavaScripts used, I've think creating a dedicated project for the client side of web development and another for service side will organize and simplify the development. solution | +-- web / client side (single html page, js, css) | - contains asp.net project, and nancy library | to host the modules in application ptoject folder | +-- application / service (nancy modules, bootstrap for other layer) | . . . and other layers (three teir, domain driven, etc) . Is this a good way of organizing a complex single page application? Am I over-engineering the web app, incurring too much complexity?

  • How to add a permanent redirect (301) for an htm file in IIS 7

    - by bconlon
    Looking in Web Analytics I could see several external sites pointing at an old .htm file on my web server that no longer existed, so I thought I would get IIS to redirect to the new .aspx replacement. How hard could it be? This has annoyed me for quite a while today so here is the answer. 1. Install the Http Redirection module - this is not installed by default!! Windows 7 Start->Control Panel->Programs and Features->Turn Windows Features on or off. Internet Information Services->World Wide Web Services->Common Http Features->HTTP Redirection. Windows Server 2008 Start->Administrative Tools->Server Manager. Roles->Web Server (IIS). Role Services->Add Role Services. Common Http Features->HTTP Redirection. 2. Edit your web.config file <configuration>     .....     <location path="oldfile.htm">         <system.webServer>             <httpRedirect enabled="true" destination="/newfile.aspx" exactDestination="true" childOnly="true" httpResponseStatus="Permanent" />         </system.webServer>     </location>     ..... </configuration> When a user clicks or Google crawls ‘oldfile.htm’ it will get a permanent redirect to ‘/newfile.aspx’ - and should take any Page Rank to the new file.  #

  • My .NET Technology picks for 2011

    - by shiju
    My Technology predictions for 2011 Cloud computing and Mobile application development will be the hottest trends for 2011. I hope that Windows Azure will be very hot in year 2011 and lot of cloud computing adoption will be happen with Windows Azure on 2011. Web application scalability will be the big challenge for Architects in the next year and architecture approaches like CQRS will get some attention on next year. Architects will look on different options for web application scalability and adoption of NoSQL and Document databases will be more in the year 2011. The following are the my technology picks for .Net stack Windows Azure Windows Azure will be one of the hottest technologies of 2011. Adoption of Cloud and Windows Azure will get big attention on next year. The Windows Azure platform is a flexible cloud–computing platform that lets you focus on solving business problems and addressing customer needs. No need to invest upfront on expensive infrastructure. Pay only for what you use, scale up when you need capacity and pull it back when you don’t. We handle all the patches and maintenance — all in a secure environment with over 99.9% uptime. Silverlight 5 Silverlight is becoming a common technology for variety of development platforms. You can develop Silverlight applications for web, desktop and windows phone. The new Silverlight 5 beta will be available during the starting quarter of the next year with new capabilities and lot of new features. Silverlight 5 will be powerful development platform for both web-based business apps and rich media solutions. We can expect final version of Silverlight 5 on end of 2011. Windows Phone 7 Development Tools Mobile application development will be very hot in year 2011 and Windows Phone 7 will be one of the hottest technologies of next year. You can get introduction on Windows Phone 7 Development Tools from somasegar’s blog post and MSDN documentation available from here. EF Code First I am a big fan of Entity Framework’s Code First approach and hope that Code First approach will attract more people onto Entity Framework 4. EF Code First lets you focus on domain model which will enable Domain-Driven Development for applications. I hope that DDD fans will love the EF Code First approach. The Entity Framework 4 now supports three types of approaches and these will attract different types of developer audience. ASP.NET MVC 3 The ASP.NET MVC 3 will be the hottest technology of Microsoft web stack on the next year. ASP.NET developers will widely move to the ASP.NET MVC Framework from their WebForms development. The new Razor view engine is great and it will increase the adoption of ASP.NET MVC 3. Razor the will improve the productivity when working with ASP.NET MVC 3 Views. You can build great web applications using ASP.NET MVC 3 and jQuery with better maintainability, generation of clean HTML and even better performance. In my opinion, the best technology stack for web development is ASP.NET MVC 3 and Entity Framework 4 Code First as ORM. On the next year, you can expect more articles from my blog on ASP.NET MVC 3 and Entity Framework 4 Code First. RavenDB NoSQL and Document databases will get more attention on the coming year and RavenDB will be the most notable document database in the .NET stack. RavenDB is an Open Source (with a commercial option) document database for the .NET/Windows platform developed by Ayende Rahien. RavenDB is .NET focused document database which comes with a fully functional .NET client API and supports LINQ. I have written few articles on RavenDB and you can read it from here. Managed Extensibility Framework (MEF) Many people didn't realized the power of MEF. The MEF lets you create extensible applications and provides a great solution for the runtime extensibility problem. I hope that .NET developers will more adopt the MEF on the next year for their .NET applications. You can get an excellent introduction on MEF from Anoop Madhusudanan’s blog post MEF or Managed Extensibility Framework – Creating a Zoo and Animals

  • Do you know how to move the Team Foundation Server cache

    - by Martin Hinshelwood
    There are a number of reasons why you may want to change the folder that you store the TFS Cache. It can take up “some” amount of room so moving it to another drive can be beneficial. This is the source control Cache that TFS uses to cache data from the database. Moving the Cache is pretty easy and should allow you to organise your server space a little more efficiently. You may also get a performance improvement (although small) by putting it on another drive.. Create a new directory to store the Cache. e.g. “d:\TfsCache\” Figure: Create a new folder Give the local TFS WPG group full control of the directory   Figure: You need to use the App Tier Service WPG In the application tier web.config (~\Application Tier\Web Services\web.config) add the following setting (to the appSettings section). Figure: The web.config for TFS is stored in the application folder <appsettings> ... <add value="D:\" key="dataDirectory" /> ... </appsettings> Figure: Adding this to the web.config will trigger a restart of the app pool Figure: Your web.config should look something like this The app pool will automatically recycle and Team Web Access will start using the new location.  If you then download a file (not via a proxy) a folder with a GUID should be created immediately in the folder from #1.  If the folder doesn’t appear, then you probably don’t have permissions set up properly.

  • How do I find the JavaScript that is invoked when I click on a button or a link in a web-page (part of a data mining project)?

    - by aste123
    I tried to use the 'inspect element' of the firebug addon for Firefox but it doesn't give me any link to the javascript. For example I got this from the firebug addon: < a href="javascript:" text of the link < /a But there is no link to the actual javascript or anything that I can use to directly go to the said link. How do I accomplish this? I need this as part of a personal data mining project that I am doing.

  • Getting a domain sub-directory url for a new server

    - by Xianlin
    I have an web application server running tomcat and i need to publish my APIs to internet users. However I don't have a domain name for this server and I can only put the ip address of this server (e.g. 145.XXX.XXX.XXX) to point out where my API xml files are located. I have another web server running with a domain name "http://www.webserver.com" registered on the internet and I want to make use of its domain name to server my web application server API xml files location. How can I do that? using "www.webserver.com/api" or using "api.webserver.com"? which is better? Also I wonder if I want to publish a "rstp://145.XXX.XXX.XXX" web link for video streaming purpose, can I use "rstp://www.webserver.com/api" to replace it and how to do it? I always thought the url contain domain sub-directory name cannot point to another IP address, it only can point to another folder location on the webserver itself.

  • Why do we need REST service security if we have HTTPS

    - by Vangel
    I refer to this excellent article http://www.thebuzzmedia.com/designing-a-secure-rest-api-without-oauth-authentication/ which speaks of amazon like security for web service. However I was asked a question in the team of why do we need it if we already use HTTPS. I was unable to answer as it really seems to me they may be right although gut tells me otherwise. Also is there places when providing REST services where HTTPS may not work? Like 3rd party websites? If anyone has experience in securing Web Services over the public interwebs please shed some light with your experience. Thanks in advance. EDIT: To clarify I am not speaking of user authentication but more of client authentication. The user authentication can be assumed to be plain text over HTTPS+ REST. My worry is that this still allows anyone to use the web service without my client to access it since everything is plai text although over HTTPS the client end point can still use my web service without the client application.

  • Unity works on my PC but not on the Server. What did I miss?

    - by Erik France
    I have a web service using Microsoft Unity to hook the pieces together.  It all works fine on my PC but when I put it on the web server, I receive this error message: System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail]: The value of the property 'type' cannot be parsed. The error is: Method 'GetClaimsForUser' in type 'WebService.Implementation.ClaimsRetriever' from assembly 'WebService.Implementation, Version=1.0.0.0, Culture=neutral, PublicKeyToken=62cac0f1a908971a' does not have an implementation.

  • HTTP 401 error in Windows Authentication disappears after swapping Providers

    - by Ray Cheng
    The IIS 7 on Windows 2008 R2 is acting really weird. We deploy our web apps as web sites with appcmd.exe. After they are deployed, if I browse to them, I'll get HTTP 401 errors. The web sites are only have Windows Authentication enabled and the providers are Negotiate and NTLM in such order. But if I swap the providers, the HTTP 401 error goes away. Even if I swap it back, the errors are still gone. So the order of the providers doesn't seem to matter, what matters is the swapping. It must have triggered something. Even if we delete the web site and application pool and reinstall the web sites, the errors are still gone. So far, we can't reproduce it easily since it happens randomly. Has anyone experienced this? How do I go about to troubleshoot it?

    I have an existing website that is a Ruby on Rails project. I have another server i need to transfer the existing website too. The server i wish to transfer too was originally hosting the website so has the necessary gems/configuration are installed. I have tar the current releases shared dir from the old server and transfered them over to the new server. I have then unpack the tar in the apps directory to the new location which is a different URL path. My problem is now as you can see below that the path on the current - is pointing to the old url.

  • How can I setup a group writeable directory?

    - by meder
    $ whoami meder $ cd /var/www $ sudo mkdir html $ sudo groupadd web $ sudo usermod -a -G web meder $ sudo usermod -a -G web medertest $ sudo chown meder:web html $ sudo chmod -R g+rwx html The problem is, anytime I create a new file in /var/www/html even though the group is set to web, it is only writeable by the original user. I was given the advice of setting the umask to be 002 because the default is what causes the problems. But I would have to do this for all users in that group, and as far as I know it would be tedious having all of them modify ~/.bashrc to have umask 002. Even if I can do it myself with a shell command for all of those users, it still seems too tedious. Can anyone offer any advice on having a group writeable directory?

  • Website inheritance of ownership question

    - by Adrian Denham
    I paid for a web site for my motel business, then due to my landlord actions I was placed in a position to file for bankrupcy. I asked my IT manager and web developer to close down the web site for the business. He has since then sold my web site to the new owners. I took all the photos myself and I am in at least 4 of the photos on the site. There are no changes to the site as I left it and it now states that it is under the copyright on the new owners? I am not sure what I should do as this happen 10 months ago and I have just found this out. Thank you for your help, I am in Australia.

  • PowerShell Script To Find Where SharePoint 2007 Features Are Activated

    - by Brian T. Jackett
    Recently I posted a script to find where SharePoint 2010 Features Are Activated.  I built the original version to use SharePoint 2010 PowerShell commandlets as that saved me a number of steps for filtering and gathering features at each level.  If there was ever demand for a 2007 version I could modify the script to handle that by using the object model instead of commandlets.  Just the other week a fellow SharePoint PFE Jason Gallicchio had a customer asking about a version for SharePoint 2007.  With a little bit of work I was able to convert the script to work against SharePoint 2007.   Solution    Below is the converted script that works against a SharePoint 2007 farm.  Note: There appears to be a bug with the 2007 version that does not give accurate results against a SharePoint 2010 farm.  I ran the 2007 version against a 2010 farm and got fewer results than my 2010 version of the script.  Discussing with some fellow PFEs I think the discrepancy may be due to sandboxed features, a new concept in SharePoint 2010.  I have not had enough time to test or confirm.  For the time being only use the 2007 version script against SharePoint 2007 farms and the 2010 version against SharePoint 2010 farms.    Note: This script is not optimized for medium to large farms.  In my testing it took 1-3 minutes to recurse through my demo environment.  This script is provided as-is with no warranty.  Run this in a smaller dev / test environment first. 001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033 034 035 036 037 038 039 040 041 042 043 044 045 046 047 048 049 050 051 052 053 054 055 056 057 058 059 060 061 062 063 064 065 066 067 068 069 070 function Get-SPFeatureActivated { # see full script for help info, removed for formatting [CmdletBinding()] param(     [Parameter(position = 1, valueFromPipeline=$true)]     [string]     $Identity )#end param     Begin     {         # load SharePoint assembly to access object model         [void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")             # declare empty array to hold results.

  • How to implement smart card authentication with a .NET Fat client?

    - by John Nevermore
    I know very little about smart card authentication in general so please point out or correct me if anything below doesn't make sense. Lets say i have: A Certificate Authority "X"-s smart card (non-exportable private key) Drivers for that smart card written in C A smart card reader CA-s authentication OCSP web service A requirement to implement user authentication in a .NET fat client application via a smart card, that was given out by the CA "X". I tried searching info on the web but no prevail. What would the steps be ? My first thought was: Set up a web service, that would allow saving of (for example) scores of a ping pong game for each user. Each time someone tries to submit a score via the client application, he can only do so by inserting the smart card into the reader. Then the public key is read from the smart card by native c calls through .NET and sent to my custom web service, which in return uses the CA-s authentication OCSP web service to prove the validity of the public key/public certificate (?). If the public key is okay and valid, encrypt a random sequence of bytes with the public key and send it to the client application. If the client application sends back the correctly decrypted random sequence of bytes along with the score of the ping pong game, then the score is saved in the database for the given user. My question is, is this the correct way to do it ? What else should i know about smart card authentication ?

  • What is SOA ?

    - by llaszews
    First, let’s mention what SOA is not: • SOA is not the same thing as web services. Web Services implies the use of standard such as Java/JAX-RPC, .NET or REST. Web Services also implies the use of a WSDL, SOAP, and/or J2EE Connector Architecture (J2EE CA) and HTTP. SOA architectures can be implemented using J2EE CA, XML file transfer or Remote Procedural Call (RPC) over File Transfer Protocol (FTP), TCP/IP, Remote Method Invocation (RMI) or other protocols. In other words, Web Services are a very specific set of technologies. SOA is a concept and can be implemented in many different ways. Some very rudimentary, such as transfering flat files between applications. • SOA will not solve all of your problems. It will make your business more agile, increase business visibility, reduce integration costs and provide better reuse. However, if you don’t need help in these area or expect SOA to cure all of your IT problems, you are looking in the wrong place. • The concepts behind SOA are not new, but SOA is also not mature. SOA as it stands today has really only been around for 5 years. The concepts of standards based protocol handlers, predefined communication schemas and remote method invocation have been around for decades. So, what is SOA? SOA is an architectural blueprint, a way of developing applications, and a set of best practices. SOA is not an ‘out of the box’ solution you buy, install and then have up and running in a matter of months. SOA is a journey to a better way of doing business and the technology architecture to support this better way of doing business. SOA is also a broader set of technologies including more then just web services. Techologies like an Enterpirse Service Bus (ESB), Business Processs Execution Language (BPEL), message queues and Business Activity Monitoring (BAM) all are part of a SOA architecture.

  • Using HTML5 Today part 4&ndash;What happened to XHTML?

    - by Steve Albers
    This is the fourth entry in a series of descriptions & demos from the “Using HTML5 Today” user group presentation. For practical purposes, the original XHTML standard is a historical footnote, although XHTML transitional will probably live on forever in the default web page templates of old web page editors. The original XHTML spec was released in 2000, on the heels of the HTML 4.01 spec.  The plan was to move web development away from HTML to the more formal, rigorous approach that XHTML offered, but it was built on a principle that conflicts with the history and culture of the Internet: XHTML introduced the idea of Draconian Error Handling, which essentially means that invalid XML markup on a page will cause a page to stop rendering. There is a transitional mode offered in the original XHTML spec, but the goal was to move to D.E.H.  You can see the result by changing the doc type for a document to “application/xhtml+xml” - for my class example we change this setting in the web.config file: <staticContent> <remove fileExtension=".html" /> <mimeMap fileExtension=".html" mimeType="application/xhtml+xml" /> </staticContent> With the new strict syntax a simple error, in this case a duplicate </td> tag, can cause a critical page error: While XHTML became very popular in the ensuing decade, the Strict form of XHTML never achieved widespread use. Draconian Error Handling was one of the factors that led in time to the creation of the WHATWG, or Web Hypertext Application Technology Group.  WHATWG contributed to the eventually disbanding of the XHTML 2.0 working group and the W3C’s move to embrace the HTML5 standard. For developers who long for XML markup the W3C HTML5 standard includes an XHTML5 syntax. For the longer, more definitive look at what happened to XHTML and how HTML5 came to be check out the Dive Into HTML mirror site or Bruce Lawson’s “HTML5: Who, What, When Why” talk.

  • How I Built My First Paid Website

    I have been a web master or a website administrator for around a year or so, initially I built two sites which were entirely made using a free domain registrar and a free web host. The free things are always got at the cost of quality. It applied here as well, the main problem I faced with free web host was that their server up time was very low, most of the times the server was down and another problem was server overload, since lots of websites were built on a single server, the load on the server was very...
