  • Can web apps allow fast data-typists to "type-ahead"?

    - by user61852
    In some data entry contexts, I've seen data typists, type really fast and know so well the app they use, and have a mechanic quality in their work so that they can "type ahead", ie continue typing and "tab-bing" and "enter-ing" faster than the display updates, so that in many occasions they are typing in the data for the next form before it draws itself. Then when this next entry form appears, their keystrokes fill the text boxes and they continue typing, selecting etc. In contexts like this, this speed is desirable, since this persons are really productive. I think this "type ahead of time" is only possible in desktop apps, but I may be wrong. My question is whether this way of handling the keyboard buffer (which in desktop apps require no extra programming) is achievable in web apps, or is this impossible because of the way web apps work, handle sessions, etc (network latency and the overhead of generating new web pages ) ? Edit: By "type ahead" I mean "keyboard type ahead" (typing faster than the next entry form can load), not suggets-as-you-type-like-google type ahead. Typeahead is a feature of computers and software (and some typewriters) that enables users to continue typing regardless of program or computer operation—the user may type in whatever speed he or she desires, and if the receiving software is busy at the time it will be called to handle this later. Often this means that keystrokes entered will not be displayed on the screen immediately. This programming technique for handling user what is known as a keyboard buffer.

  • EPM 11.1.2.2 Architecture: Financial Performance Management Applications

    - by Marc Schumacher
     Financial Management can be accessed either by a browser based client or by SmartView. Starting from release 11.1.2.2, the Financial Management Windows client does not longer access the Financial Management Consolidation server. All tasks that require an on line connection (e.g. load and extract tasks) can only be done using the web interface. Any client connection initiated by a browser or SmartView is send to the Oracle HTTP server (OHS) first. Based on the path given (e.g. hfmadf, hfmofficeprovider) in the URL, OHS makes a decision to forward this request either to the new Financial Management web application based on the Oracle Application Development Framework (ADF) or to the .NET based application serving SmartView retrievals running on Internet Information Server (IIS). Any requests send to the ADF web interface that need to be processed by the Financial Management application server are send to the IIS using HTTP protocol and will be forwarded further using DCOM to the Financial Management application server. SmartView requests, which are processes by IIS in first row, are forwarded to the Financial Management application server using DCOM as well. The Financial Management Application Server uses OLE DB database connections via native database clients to talk to the Financial Management database schema. Communication between the Financial Management DME Listener, which handles requests from EPMA, and the Financial Management application server is based on DCOM.  Unlike most other components Essbase Analytics Link (EAL) does not have an end user interface. The only user interface is a plug-in for the Essbase Administration Services console, which is used for administration purposes only. End users interact with a Transparent or Replicated Partition that is created in Essbase and populated with data by EAL. The Analytics Link Server deployed on WebLogic communicates through HTTP protocol with the Analytics Link Financial Management Connector that is deployed in IIS on the Financial Management web server. Analytics Link Server interacts with the Data Synchronisation server using the EAL API. The Data Synchronization server acts as a target of a Transparent or Replicated Partition in Essbase and uses a native database client to connect to the Financial Management database. Analytics Link Server uses JDBC to connect to relational repository databases and Essbase JAPI to connect to Essbase.  As most Oracle EPM System products, browser based clients and SmartView can be used to access Planning. The Java based Planning web application is deployed on WebLogic, which is configured behind an Oracle HTTP Server (OHS). Communication between Planning and the Planning RMI Registry Service is done using Java Remote Message Invocation (RMI). Planning uses JDBC to access relational repository databases and talks to Essbase using the CAPI. Be aware of the fact that beside the Planning System database a dedicated database schema is needed for each application that is set up within Planning.  As Planning, Profitability and Cost Management (HPCM) has a pretty simple architecture. Beside the browser based clients and SmartView, a web service consumer can be used as a client too. All clients access the Java based web application deployed on WebLogic through Oracle HHTP Server (OHS). Communication between Profitability and Cost Management and EPMA Web Server is done using HTTP protocol. JDBC is used to access the relational repository databases as well as data sources. Essbase JAPI is utilized to talk to Essbase.  For Strategic Finance, two clients exist, SmartView and a Windows client. While SmartView communicates through the web layer to the Strategic Finance Server, Strategic Finance Windows client makes a direct connection to the Strategic Finance Server using RPC calls. Connections from Strategic Finance Web as well as from Strategic Finance Web Services to the Strategic Finance Server are made using RPC calls too. The Strategic Finance Server uses its own file based data store. JDBC is used to connect to the EPM System Registry from web and application layer.  Disclosure Management has three kinds of clients. While the browser based client and SmartView interact with the Disclosure Management web application directly through Oracle HTTP Server (OHS), Taxonomy Designer does not connect to the Disclosure Management server. Communication to relational repository databases is done via JDBC, to connect to Essbase the Essbase JAPI is utilized.

  • Facebook App EULA & Restrictions: What can't they do that my web app can?

    - by Adam Tannon
    I have written a nifty little web app (in Java/GWT/JS) and have been experimenting with the idea of making it available through Facebook as a Facebook App as well. After spending some time reading Facebook's developer docs, it seems like I can just create a Facebook App to point at any URL I want and use that as the app/canvas. It accomplishes this via iframes. So, my tentative plan is to just point it towards my (existing) web app so that I don't have to totally re-write it. But then that got me thinking: Facebook must regulate what sorts of things can be done through a Facebook App, vs. what an app can't do. For instance, I can't imagine I can point a Facebook App to point at a URL for a web app that accepts e-commerce payments (that would by-pass Facebook altogether and not allow them to take a cut from the ecom transaction!). Also, I can't imagine that Facebook allows developers to point their Facebook Apps to just any old URL without some sort of a scan, otherwise that would open Facebook up to the horrors of every security threat knownst to humanity. I know for a fact that when you write an iOS native app and put it up on the Apple App Store, that Apple actually scans your source code for violations of their EULA. So my question: does Facebook do the same? If so, what are their terms & conditions for what a Facebook app can/can't do? Suprisingly, I can't find this anywhere!! Thanks in advance!

  • Is my project a web site or a mobile app?

    - by Evik James
    I am a web developer. I have been developing web sites professionally for 15+ years using ColdFusion, SQL Server, and jQuery. I am doing a project for a client that uses the above technologies. The site has a mobile facet too. For that, I am using jQuery Mobile. The site enables retail store personnel to gather a store customer's preferences using any smart phone or tablet. The store personnel just needs to access a special link via a QR code and a login. Anyone can easily access the site from a PC's browser, too. Some sources suggest that mobile apps must be downloaded and installed using a third party, such as from Google, Amazon, or Apple. Others sources suggest that any information designed for use on mobile device is a mobile app. Regarding the site that is specifically designed for use by mobile devices that extensively uses jQuery Mobile, is this a "web site" or a "mobile app"? What is the "proper" description for this type of site? My customer insists that it is one and not the other. I insist that it is the other and not the one. Can you help me clarify this?

  • .NET: understanding web.config in asp.net

    - by mark smith
    Hi there, Does anyone know of a good link to explain how to use the web.config...... For example, i am using forms authentication... and i notice there is a system.web and then it closed /system.web and then below configuration there are additional location tags here is an example, if you ntoice there is an authentication mode=forms with authorization i presume this is the ROOT....... It is also self contained within a system.web .... Below this there are more location= with system.web tags.... I have never really understand what i am actually doing.. I have tried checkign the MSDN documentation but still i don't fully understand up.... Can anyone help? If you notice with my example.... everything is stored in 1 web.config... i thought the standard waas create a standard web.config and then create another web.config in the directory where i wish to protect it..??? <configuration> <system.web> <compilation debug="true" strict="false" explicit="true" targetFramework="4.0" /> <authentication mode="Forms"> <forms loginUrl="Login.aspx" defaultUrl="Login.aspx" cookieless="UseCookies" timeout="60"/> </authentication> <authorization> <allow users="*"/> </authorization> </system.web> <location path="Forms"> <system.web> <authorization> <deny users="?"/> <allow users="*"/> </authorization> </system.web> </location> <location path="Forms/Seguridad"> <system.web> <authorization> <allow roles="Administrador"/> <deny users="?"/> </authorization> </system.web> </location>

  • How to pass initialisation parameters to a web service in Netbeans

    - by Bob Roberts
    I have built a web web service with Netbeans 6.8 using the "Web Service from WSDL" wizard. It has generated the binding classes and a skeleton for the class implementing the web service. I've set some initialization parameters in web.xml, under the servlet corresponding to the web service. Now I'd like to pass those parameters to the class implementing the web service. How can this be achieved (preferably without editing any of the code auto-generated by Netbeans)?

  • Difference between Website and Web Application in ASP.NET

    - by SAMIR BHOGAYTA
    Web site in Visual Studio 2005: A web site is just a group of all files in a folder and sub folders. There is no project file. All files under the specific folder - including your word documents, text files, images etc are part of the web site. You have to deploy all files including source files (unless you pre compile them) to the server. Files are compiled dynamically during run time. To create a "web site", you need to use the menu File New Website You will have the option to choose either one of the following location types: # File System - Allows you to choose a folder to put all the files. # Http - Allows you to choose a virtual directory to put the files. # FTP - Allows you to choose an ftp location. In any of the above cases, no project file is created automatically. Visual Studio considers all files under the folder are part of the web site. There will be no single assembly created and you will nto see a "Bin" folder. The benefits of this model is, you do not need a project file or virtual directory to open a project. It is very handy when you share or download code from the internet. You just need to copy the downloaded code into a folder and you are ready to go! Web Application Project in Visual Studio 2005: Microsoft introduced the "web site" concept where all files under a web site are part of the site, hoping that the development community is going to love that. In fact, this is very usefull to share code. However, they did not consider millions of existing web applications where people are comfortable with the "project" based application. Also, there were lot of web applications where several un wanted files were kept under the web site folder. So, the new model did not work well for them. When people started screaming, Microsoft came up with the answer. On April 7, 2006, they announced "Visual Studio 2005 Web Application Projects" as an Add-On to Visual Studio 2005. This Add-On will allow you to create and use web applications just like the way it used to be in Visual Studio 2003. The Visual Studio 2005 Web Application Project model uses the same project, build and compilation method as the Visual Studio .NET 2003 web project model. All code files within the project are compiled into a single assembly that is built and copied in the Bin directory. All files contained within the project are defined within a project file (as well as the assembly references and other project meta-data settings). Files under the web's file-system root that are not defined in the project file are not considered part of the web project.

  • Our Favorite Highlights from OpenWorld 2012

    - by Kathy.Miedema
    By Kathy Miedema and Misha Vaughan, Oracle Applications User Experience The Oracle Applications User Experience (UX) team’s activities around OpenWorld expand every year, but this year we certainly raised the bar.   Members of our team helped deliver three, separate, all-day training events in the week prior to OpenWorld. Our Fusion User Experience Advocates (FXA) and Applications UX Sales Ambassadors (SAMBA) have all-new material around the Oracle user experience to deliver at conferences in the coming year - Fusion Applications design patterns, mobile design patterns, and the new face of Fusion. We also delivered a hands-on workshop sharing user experience tools for our customers that is designed to answer this question: "If I have no UX staff, what do I do?" We also spent the weeks just before OpenWorld preparing to talk about the new face of Fusion Applications, a greatly simplified entry experience into Fusion Applications for self-service users, CRM users, and IT managers who want to change the look and feel quickly. Special thanks to Oracle ACE Director Floyd Teter for the first mention of our project.Jeremy Ashley, VP, Oracle Applications User Experience Customers may have seen one of the many OpenWorld session demos of the new face of Fusion, which will be available with Fusion Applications soon. It was shown in sessions by Oracle's Chris Leone, Anthony Lye, and our own Vice President, Jeremy Ashley, among others.   Leone reinforced the importance of user experience as one of three main design principles for Fusion Applications, emphasizing that Fusion was designed from the beginning to be intelligent, social, and mobile. User experience highlights of the new face of Fusion, he said, included the need for "zero training," and he called the experience "easy to use." He added that deploying it for HCM self-service would be effortless.  Customers take part in a usability lab tour during OpenWorld 2012. Customers also may have seen the new face of Fusion on the demogrounds or during one of our teams' chartered lab tours at the end of the week. We tested other new designs at our on-site lab in the Intercontinental Hotel, next to Moscone West. Applications User Experience team members show eye-tracking and mobile demos at OOW. We were also excited to kick off new branches of the Oracle Usability Advisory Board, which now has groups in Latin America and the Middle East, in addition to North America and EMEA.   And we were pleasantly surprised by the interest in one of our latest research projects, Oracle Voice, which is designed to enable faster data input for on-the-go users. We offer a big thank-you to the Nuance demopod for sharing the demo with OpenWorld attendees.  For more information on our program and products like the new face of Fusion, please comment below.

  • Go for Zend framework or Django for a modular web application?

    - by dr. squid
    I am using both Zend framework and Django, and they both have they strengths and weakness, but they are both good framworks in their own way. I do want to create a highly modular web application, like this example: modules: Admin cms articles sections ... ... ... I also want all modules to be self contained with all confid and template files. I have been looking into a way to solve this is zend the last days, but adding one omer level to the module setup doesn't feel right. I am sure this could be done, but should I? I have also included Doctrine to my zend application that could give me even more problems in my module setup! When we are talking about Django this is easy to implement (Easy as in concept, not in implementation time or whatever) and a great way to create web apps. But one of the downsides of Django is the web hosing part. There are some web hosts offering Django support, but not that many.. So then I guess the question is what have the most value; rapid modular development versus hosting options! Well, comments are welcome! Thanks

  • Single hardware unit to protect web servers and implement smart publishing

    - by Maxim V. Pavlov
    Thus far we've been using the combination of Forefront TMG 2010 as an edge firewall + intrusion prevention system + web site publishing mechanism in the data center to work with a few web server machines. Since we develop on ASP.NET, we are IIS and in general - Microsoft crowd. Since TMG is being deprecated, we need to come up with a hardware alternative to protect and serve our data center web cloud. Could you please advise a hardware or virtual appliance solution that can provide routing, flood prevention and smart web-site publishing (one IP - many web sites based on domain name filter) all in one. Even if it is hard to configure, as long as it covers all these features, we will invest to learn and replace TMG eventually.

  • Web application design with distributed servers

    - by Bonn
    I want to build a web application/server with this structure: main-server sub-server transaction-server (create, update, delete) view-server (view, search) authentication-server documents-server reporting-server library-server e-learning-server The main-server acts as host server for sub-server. I can add many sub-servers and connect it to main-server (via plug-play interface maybe), then it can begin querying data from another sub-servers (which has been connected to the main-server). The sub-servers can be anywhere as long as connected to internet. The main-server can manage all sub-servers which are connected to it (query data, setting permission between sub-servers, etc). The purpose is simple, the web application will be huge as the company grows, so I want to distribute it into small connected plug-able servers. My question is, does the structure above already have a standardized method? or are there any different views? what are the technologies needed? I need a lot of researches before the execution plan begin. thanks a lot.

The Windows Azure Import/Export Service enables you to move large amounts of on-premises data into and out of your Windows Azure Storage accounts. It does this by enabling you to securely ship hard disk drives directly to our Windows Azure data centers. Once we receive the drives we’ll automatically transfer the data to or from your Windows Azure Storage account.  This enables you to import or export massive amounts of data more quickly and cost effectively (and not be constrained by available network bandwidth). Encrypted Transport Our Import/Export service provides built-in support for BitLocker disk encryption – which enables you to securely encrypt data on the hard drives before you send it, and not have to worry about it being compromised even if the disk is lost/stolen in transit (since the content on the transported hard drives is completely encrypted and you are the only one who has the key to it).  The drive preparation tool we are shipping today makes setting up bitlocker encryption on these hard drives easy. How to Import/Export your first Hard Drive of Data You can read our Getting Started Guide to learn more about how to begin using the import/export service.  You can create import and export jobs via the Windows Azure Management Portal as well as programmatically using our Server Management APIs. It is really easy to create a new import or export job using the Windows Azure Management Portal.  Simply navigate to a Windows Azure storage account, and then click the new Import/Export tab now available within it (note: if you don’t have this tab make sure to sign-up for the Import/Export preview): Then click the “Create Import Job” or “Create Export Job” commands at the bottom of it.  This will launch a wizard that easily walks you through the steps required: For more comprehensive information about Import/Export, refer to Windows Azure Storage team blog.  You can also send questions and comments to the [email protected] email address. We think you’ll find this new service makes it much easier to move data into and out of Windows Azure, and it will dramatically cut down the network bandwidth required when working on large data migration projects.  We hope you like it. HDInsight: 100% Compatible Hadoop Service in the Cloud Last week we announced the general availability release of Windows Azure HDInsight. HDInsight is a 100% compatible Hadoop service that allows you to easily provision and manage Hadoop clusters for big data processing in Windows Azure.  This release is now live in production, backed by an enterprise SLA, supported 24x7 by Microsoft Support, and is ready to use for production scenarios. HDInsight allows you to use Apache Hadoop tools, such as Pig and Hive, to process large amounts of data in Windows Azure Blob Storage. Because data is stored in Windows Azure Blob Storage, you can choose to dynamically create Hadoop clusters only when you need them, and then shut them down when they are no longer required (since you pay only for the time the Hadoop cluster instances are running this provides a super cost effective way to use them).  You can create Hadoop clusters using either the Windows Azure Management Portal (see below) or using our PowerShell and Cross Platform Command line tools: The import/export hard drive support that came out today is a perfect companion service to use with HDInsight – the combination allows you to easily ingest, process and optionally export a limitless amount of data.  We’ve also integrated HDInsight with our Business Intelligence tools, so users can leverage familiar tools like Excel in order to analyze the output of jobs.  You can find out more about how to get started with HDInsight here. Virtual Machines: VM Gallery Enhancements Today’s update of Windows Azure brings with it a new Virtual Machine gallery that you can use to create new VMs in the cloud.  You can launch the gallery by doing New->Compute->Virtual Machine->From Gallery within the Windows Azure Management Portal: The new Virtual Machine Gallery includes some nice enhancements that make it even easier to use: Search: You can now easily search and filter images using the search box in the top-right of the dialog.  For example, simply type “SQL” and we’ll filter to show those images in the gallery that contain that substring. Category Tree-view: Each month we add more built-in VM images to the gallery.  You can continue to browse these using the “All” view within the VM Gallery – or now quickly filter them using the category tree-view on the left-hand side of the dialog.  For example, by selecting “Oracle” in the tree-view you can now quickly filter to see the official Oracle supplied images. MSDN and Supported checkboxes: With today’s update we are also introducing filters that makes it easy to filter out types of images that you may not be interested in. The first checkbox is MSDN: using this filter you can exclude any image that is not part of the Windows Azure benefits for MSDN subscribers (which have highly discounted pricing - you can learn more about the MSDN pricing here). The second checkbox is Supported: this filter will exclude any image that contains prerelease software, so you can feel confident that the software you choose to deploy is fully supported by Windows Azure and our partners. Sort options: We sort gallery images by what we think customers are most interested in, but sometimes you might want to sort using different views. So we’re providing some additional sort options, like “Newest,” to customize the image list for what suits you best. Pricing information: We now provide additional pricing information about images and options on how to cost effectively run them directly within the VM Gallery. The above improvements make it even easier to use the VM Gallery and quickly create launch and run Virtual Machines in the cloud. Virtual Machines: ACL Support for VIPs A few months ago we exposed the ability to configure Access Control Lists (ACLs) for Virtual Machines using Windows PowerShell cmdlets and our Service Management API. With today’s release, you can now configure VM ACLs using the Windows Azure Management Portal as well. You can now do this by clicking the new Manage ACL command in the Endpoints tab of a virtual machine instance: This will enable you to configure an ordered list of permit and deny rules to scope the traffic that can access your VM’s network endpoints. For example, if you were on a virtual network, you could limit RDP access to a Windows Azure virtual machine to only a few computers attached to your enterprise. Or if you weren’t on a virtual network you could alternatively limit traffic from public IPs that can access your workloads: Here is the default behaviors for ACLs in Windows Azure: By default (i.e. no rules specified), all traffic is permitted. When using only Permit rules, all other traffic is denied. When using only Deny rules, all other traffic is permitted. When there is a combination of Permit and Deny rules, all other traffic is denied. Lastly, remember that configuring endpoints does not automatically configure them within the VM if it also has firewall rules enabled at the OS level.  So if you create an endpoint using the Windows Azure Management Portal, Windows PowerShell, or REST API, be sure to also configure your guest VM firewall appropriately as well. Web Sites: Web Sockets Support With today’s release you can now use Web Sockets with Windows Azure Web Sites.  This feature enables you to easily integrate real-time communication scenarios within your web based applications, and is available at no extra charge (it even works with the free tier).  Higher level programming libraries like SignalR and socket.io are also now supported with it. You can enable Web Sockets support on a web site by navigating to the Configure tab of a Web Site, and by toggling Web Sockets support to “on”: Once Web Sockets is enabled you can start to integrate some really cool scenarios into your web applications.  Check out the new SignalR documentation hub on www.asp.net to learn more about some of the awesome scenarios you can do with it. Web Sites: Remote Debugging Support The Windows Azure SDK 2.2 we released two weeks ago introduced remote debugging support for Windows Azure Cloud Services. With today’s Windows Azure release we are extending this remote debugging support to also work with Windows Azure Web Sites. With live, remote debugging support inside of Visual Studio, you are able to have more visibility than ever before into how your code is operating live in Windows Azure. It is now super easy to attach the debugger and quickly see what is going on with your application in the cloud. Remote Debugging of a Windows Azure Web Site using VS 2013 Enabling the remote debugging of a Windows Azure Web Site using VS 2013 is really easy.  Start by opening up your web application’s project within Visual Studio. Then navigate to the “Server Explorer” tab within Visual Studio, and click on the deployed web-site you want to debug that is running within Windows Azure using the Windows Azure->Web Sites node in the Server Explorer.  Then right-click and choose the “Attach Debugger” option on it: When you do this Visual Studio will remotely attach the debugger to the Web Site running within Windows Azure.  The debugger will then stop the web site’s execution when it hits any break points that you have set within your web application’s project inside Visual Studio.  For example, below I set a breakpoint on the “ViewBag.Message” assignment statement within the HomeController of the standard ASP.NET MVC project template.  When I hit refresh on the “About” page of the web site within the browser, the breakpoint was triggered and I am now able to debug the app remotely using Visual Studio: Note above how we can debug variables (including autos/watchlist/etc), as well as use the Immediate and Command Windows. In the debug session above I used the Immediate Window to explore some of the request object state, as well as to dynamically change the ViewBag.Message property.  When we click the the “Continue” button (or press F5) the app will continue execution and the Web Site will render the content back to the browser.  This makes it super easy to debug web apps remotely. Tips for Better Debugging To get the best experience while debugging, we recommend publishing your site using the Debug configuration within Visual Studio’s Web Publish dialog. This will ensure that debug symbol information is uploaded to the Web Site which will enable a richer debug experience within Visual Studio.  You can find this option on the Web Publish dialog on the Settings tab: When you ultimately deploy/run the application in production we recommend using the “Release” configuration setting – the release configuration is memory optimized and will provide the best production performance.  To learn more about diagnosing and debugging Windows Azure Web Sites read our new Troubleshooting Windows Azure Web Sites in Visual Studio guide. Notification Hubs: Segmented Push Notification support with tag expressions In August we announced the General Availability of Windows Azure Notification Hubs - a powerful Mobile Push Notifications service that makes it easy to send high volume push notifications with low latency from any mobile app back-end.  Notification hubs can be used with any mobile app back-end (including ones built using our Mobile Services capability) and can also be used with back-ends that run in the cloud as well as on-premises. Beginning with the initial release, Notification Hubs allowed developers to send personalized push notifications to both individual users as well as groups of users by interest, by associating their devices with tags representing the logical target of the notification. For example, by registering all devices of customers interested in a favorite MLB team with a corresponding tag, it is possible to broadcast one message to millions of Boston Red Sox fans and another message to millions of St. Louis Cardinals fans with a single API call respectively. New support for using tag expressions to enable advanced customer segmentation With today’s release we are adding support for even more advanced customer targeting.  You can now identify customers that you want to send push notifications to by defining rich tag expressions. With tag expressions, you can now not only broadcast notifications to Boston Red Sox fans, but take that segmenting a step farther and reach more granular segments. This opens up a variety of scenarios, for example: Offers based on multiple preferences—e.g. send a game day vegetarian special to users tagged as both a Boston Red Sox fan AND a vegetarian Push content to multiple segments in a single message—e.g. rain delay information only to users who are tagged as either a Boston Red Sox fan OR a St. Louis Cardinal fan Avoid presenting subsets of a segment with irrelevant content—e.g. season ticket availability reminder to users who are tagged as a Boston Red Sox fan but NOT also a season ticket holder To illustrate with code, consider a restaurant chain app that sends an offer related to a Red Sox vs Cardinals game for users in Boston. Devices can be tagged by your app with location tags (e.g. “Loc:Boston”) and interest tags (e.g. “Follows:RedSox”, “Follows:Cardinals”), and then a notification can be sent by your back-end to “(Follows:RedSox || Follows:Cardinals) && Loc:Boston” in order to deliver an offer to all devices in Boston that follow either the RedSox or the Cardinals. This can be done directly in your server backend send logic using the code below: var notification = new WindowsNotification(messagePayload); hub.SendNotificationAsync(notification, "(Follows:RedSox || Follows:Cardinals) && Loc:Boston"); In your expressions you can use all Boolean operators: AND (&&), OR (||), and NOT (!).  Some other cool use cases for tag expressions that are now supported include: Social: To “all my group except me” - group:id && !user:id Events: Touchdown event is sent to everybody following either team or any of the players involved in the action: Followteam:A || Followteam:B || followplayer:1 || followplayer:2 … Hours: Send notifications at specific times. E.g. Tag devices with time zone and when it is 12pm in Seattle send to: GMT8 && follows:thaifood Versions and platforms: Send a reminder to people still using your first version for Android - version:1.0 && platform:Android For help on getting started with Notification Hubs, visit the Notification Hub documentation center.  Then download the latest NuGet package (or use the Notification Hubs REST APIs directly) to start sending push notifications using tag expressions.  They are really powerful and enable a bunch of great new scenarios. TFS & GIT: Continuous Delivery Support for Web Sites + Cloud Services With today’s Windows Azure release we are making it really easy to enable continuous delivery support with Windows Azure and Team Foundation Services.  Team Foundation Services is a cloud based offering from Microsoft that provides integrated source control (with both TFS and Git support), build server, test execution, collaboration tools, and agile planning support.  It makes it really easy to setup a team project (complete with automated builds and test runners) in the cloud, and it has really rich integration with Visual Studio. With today’s Windows Azure release it is now really easy to enable continuous delivery support with both TFS and Git based repositories hosted using Team Foundation Services.  This enables a workflow where when code is checked in, built successfully on an automated build server, and all tests pass on it – I can automatically have the app deployed on Windows Azure with zero manual intervention or work required. The below screen-shots demonstrate how to quickly setup a continuous delivery workflow to Windows Azure with a Git-based ASP.NET MVC project hosted using Team Foundation Services. Enabling Continuous Delivery to Windows Azure with Team Foundation Services The project I’m going to enable continuous delivery with is a simple ASP.NET MVC project whose source code I’m hosting using Team Foundation Services.  I did this by creating a “SimpleContinuousDeploymentTest” repository there using Git – and then used the new built-in Git tooling support within Visual Studio 2013 to push the source code to it.  Below is a screen-shot of the Git repository hosted within Team Foundation Services: I can access the repository within Visual Studio 2013 and easily make commits with it (as well as branch, merge and do other tasks).  Using VS 2013 I can also setup automated builds to take place in the cloud using Team Foundation Services every time someone checks in code to the repository: The cool thing about this is that I don’t have to buy or rent my own build server – Team Foundation Services automatically maintains its own build server farm and can automatically queue up a build for me (for free) every time someone checks in code using the above settings.  This build server (and automated testing) support now works with both TFS and Git based source control repositories. Connecting a Team Foundation Services project to Windows Azure Once I have a source repository hosted in Team Foundation Services with Automated Builds and Testing set up, I can then go even further and set it up so that it will be automatically deployed to Windows Azure when a source code commit is made to the repository (assuming the Build + Tests pass).  Enabling this is now really easy.  To set this up with a Windows Azure Web Site simply use the New->Compute->Web Site->Custom Create command inside the Windows Azure Management Portal.  This will create a dialog like below.  I gave the web site a name and then made sure the “Publish from source control” checkbox was selected: When we click next we’ll be prompted for the location of the source repository.  We’ll select “Team Foundation Services”: Once we do this we’ll be prompted for our Team Foundation Services account that our source repository is hosted under (in this case my TFS account is “scottguthrie”): When we click the “Authorize Now” button we’ll be prompted to give Windows Azure permissions to connect to the Team Foundation Services account.  Once we do this we’ll be prompted to pick the source repository we want to connect to.  Starting with today’s Windows Azure release you can now connect to both TFS and Git based source repositories.  This new support allows me to connect to the “SimpleContinuousDeploymentTest” respository we created earlier: Clicking the finish button will then create the Web Site with the continuous delivery hooks setup with Team Foundation Services.  Now every time someone pushes source control to the repository in Team Foundation Services, it will kick off an automated build, run all of the unit tests in the solution , and if they pass the app will be automatically deployed to our Web Site in Windows Azure.  You can monitor the history and status of these automated deployments using the Deployments tab within the Web Site: This enables a really slick continuous delivery workflow, and enables you to build and deploy apps in a really nice way. Developer Analytics: New Relic support for Web Sites + Mobile Services With today’s Windows Azure release we are making it really easy to enable Developer Analytics and Monitoring support with both Windows Azure Web Site and Windows Azure Mobile Services.  We are partnering with New Relic, who provide a great dev analytics and app performance monitoring offering, to enable this - and we have updated the Windows Azure Management Portal to make it really easy to configure. Enabling New Relic with a Windows Azure Web Site Enabling New Relic support with a Windows Azure Web Site is now really easy.  Simply navigate to the Configure tab of a Web Site and scroll down to the “developer analytics” section that is now within it: Clicking the “add-on” button will display some additional UI.  If you don’t already have a New Relic subscription, you can click the “view windows azure store” button to obtain a subscription (note: New Relic has a perpetually free tier so you can enable it even without paying anything): Clicking the “view windows azure store” button will launch the integrated Windows Azure Store experience we have within the Windows Azure Management Portal.  You can use this to browse from a variety of great add-on services – including New Relic: Select “New Relic” within the dialog above, then click the next button, and you’ll be able to choose which type of New Relic subscription you wish to purchase.  For this demo we’ll simply select the “Free Standard Version” – which does not cost anything and can be used forever:  Once we’ve signed-up for our New Relic subscription and added it to our Windows Azure account, we can go back to the Web Site’s configuration tab and choose to use the New Relic add-on with our Windows Azure Web Site.  We can do this by simply selecting it from the “add-on” dropdown (it is automatically populated within it once we have a New Relic subscription in our account): Clicking the “Save” button will then cause the Windows Azure Management Portal to automatically populate all of the needed New Relic configuration settings to our Web Site: Deploying the New Relic Agent as part of a Web Site The final step to enable developer analytics using New Relic is to add the New Relic runtime agent to our web app.  We can do this within Visual Studio by right-clicking on our web project and selecting the “Manage NuGet Packages” context menu: This will bring up the NuGet package manager.  You can search for “New Relic” within it to find the New Relic agent.  Note that there is both a 32-bit and 64-bit edition of it – make sure to install the version that matches how your Web Site is running within Windows Azure (note: you can configure your Web Site to run in either 32-bit or 64-bit mode using the Web Site’s “Configuration” tab within the Windows Azure Management Portal): Once we install the NuGet package we are all set to go.  We’ll simply re-publish the web site again to Windows Azure and New Relic will now automatically start monitoring the application Monitoring a Web Site using New Relic Now that the application has developer analytics support with New Relic enabled, we can launch the New Relic monitoring portal to start monitoring the health of it.  We can do this by clicking on the “Add Ons” tab in the left-hand side of the Windows Azure Management Portal.  Then select the New Relic add-on we signed-up for within it.  The Windows Azure Management Portal will provide some default information about the add-on when we do this.  Clicking the “Manage” button in the tray at the bottom will launch a new browser tab and single-sign us into the New Relic monitoring portal associated with our account: When we do this a new browser tab will launch with the New Relic admin tool loaded within it: We can now see insights into how our app is performing – without having to have written a single line of monitoring code.  The New Relic service provides a ton of great built-in monitoring features allowing us to quickly see: Performance times (including browser rendering speed) for the overall site and individual pages.  You can optionally set alert thresholds to trigger if the speed does not meet a threshold you specify. Information about where in the world your customers are hitting the site from (and how performance varies by region) Details on the latency performance of external services your web apps are using (for example: SQL, Storage, Twitter, etc) Error information including call stack details for exceptions that have occurred at runtime SQL Server profiling information – including which queries executed against your database and what their performance was And a whole bunch more… The cool thing about New Relic is that you don’t need to write monitoring code within your application to get all of the above reports (plus a lot more).  The New Relic agent automatically enables the CLR profiler within applications and automatically captures the information necessary to identify these.  This makes it super easy to get started and immediately have a rich developer analytics view for your solutions with very little effort. If you haven’t tried New Relic out yet with Windows Azure I recommend you do so – I think you’ll find it helps you build even better cloud applications.  Following the above steps will help you get started and deliver you a really good application monitoring solution in only minutes. Service Bus: Support for partitioned queues and topics With today’s release, we are enabling support within Service Bus for partitioned queues and topics. Enabling partitioning enables you to achieve a higher message throughput and better availability from your queues and topics. Higher message throughput is achieved by implementing multiple message brokers for each partitioned queue and topic.  The  multiple messaging stores will also provide higher availability. You can create a partitioned queue or topic by simply checking the Enable Partitioning option in the custom create wizard for a Queue or Topic: Read this article to learn more about partitioned queues and topics and how to take advantage of them today. Billing: New Billing Alert Service Today’s Windows Azure update enables a new Billing Alert Service Preview that enables you to get proactive email notifications when your Windows Azure bill goes above a certain monetary threshold that you configure.  This makes it easier to manage your bill and avoid potential surprises at the end of the month. With the Billing Alert Service Preview, you can now create email alerts to monitor and manage your monetary credits or your current bill total.  To set up an alert first sign-up for the free Billing Alert Service Preview.  Then visit the account management page, click on a subscription you have setup, and then navigate to the new Alerts tab that is available: The alerts tab allows you to setup email alerts that will be sent automatically once a certain threshold is hit.  For example, by clicking the “add alert” button above I can setup a rule to send myself email anytime my Windows Azure bill goes above $100 for the month: The Billing Alert Service will evolve to support additional aspects of your bill as well as support multiple forms of alerts such as SMS.  Try out the new Billing Alert Service Preview today and give us feedback. Summary Today’s Windows Azure release enables a ton of great new scenarios, and makes building applications hosted in the cloud even easier. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • How can I get my Web API app to run again after upgrading to MVC 5 and Web API 2?

    - by Clay Shannon
    I upgraded my Web API app to the funkelnagelneu versions using this guidance: http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2 However, after going through the steps (it seems all this should be automated, anyway), I tried to run it and got, "A project with an Output Type of Class Library cannot be started directly" What in Sam Hills Brothers Coffee is going on here? Who said this was a class library? So I opened Project Properties, and changed it (it was marked as "Class Library" for some reason - it either wasn't yesterday, or was and worked fine) to an Output Type of "Windows Application" ("Console Application" and "Class Library" being the only other options). Now it won't compile, complaining: "*Program 'c:\Platypus_Server_WebAPI\PlatypusServerWebAPI\PlatypusServerWebAPI\obj\Debug\PlatypusServerWebAPI.exe' does not contain a static 'Main' method suitable for an entry point...*" How can I get my Web API app back up and running in view of this quandary? UPDATE Looking in packages.config, two entries seem chin-scratch-worthy: <package id="Microsoft.AspNet.Providers" version="1.2" targetFramework="net40" /> <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net40" /> All the others target net451. Could this be the problem? Should I remove these packages? UPDATE 2 I tried to uninstall the Microsoft.Web.Infrastructure package (its description leads me to believe I don't need it; also, it has no dependencies) via the NuGet package manager, but it tells me, "NuGet failed to install or uninstall the selected package in the following project(s). [mine]" UPDATE 3 I went through the steps in again, and found that I had missed one step. I had to change this entry in the Application web.config File : <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" /> </dependentAssembly> (from "4.0.0.0" to "5.0.0.0") ...but I still get the same result - it rebuilds/compiles, but won't run, with "A project with an Output Type of Class Library cannot be started directly" UPDATE 4 Thinking about the err msg, that it can't directly open a class library, I thought, "Sure you can't/won't -- this is a web app, not a project. So I followed a hunch, closed the project, and reopened it as a website (instead of reopening a project). That has gotten me further, at least; now I see a YSOD: Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. UPDATE 5 Note: The project is now (after being opened as a web site) named "localhost_48614" And...there is no longer a "References" folder...?!?!? As to that YSOD I'm getting, the official instructions (http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2) said to do this, and I quote: "Update all elements that contain “System.Web.WebPages.Razor” from version “2.0.0.0” to version“3.0.0.0”." UPDATE 6 When I select Tools Library Package Manager Manage NuGet Packages for Solution now, I get, "Operation failed. Unable to locate the solution directory. Please ensure that the solution has been saved." So I save it, and it saves it with this funky new name (C:\Users\clay\Documents\Visual Studio 2013\Projects\localhost_48614\localhost_48614.sln) I get the Yellow Strip of Enlightenment across the top of the NuGet Package Manager telling me, "Some NuGet packages are missing from this solution. Click to restore from your online package sources." I do (click the "Restore" button, that is), and it downloads the missing packages ... I end up with the 30 packages. I try to run the app/site again, and ... the erstwhile YSOD becomes a compilation error: The pre-application start initialization method Start on type System.Web.Mvc.PreApplicationStartCode threw an exception with the following error message: Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.. Argghhhh!!! (and it's not even talk-like-a-pirate day).

  • Why did the web win the space of remote applications and X not?

    - by Martin Josefsson
    The X Window System is 25 years old, it had it's birthday yesterday (on the 15'th). As you probably are aware of, one of it's most important features is the separation of the server side and the client side in a way that neither Microsoft's, Apples or Wayland's windowing systems have. Back in the days (sorry for the ambiguous phrasing) many believed X would dominate over other ways to make windows because of this separation of server and client, allowing the application to be ran on a server somewhere else while the user clicks and types on her own computer at home. This use obviously still exists, but is marginalized at best. When we write and use programs that run on a server we almost always use the web with it's html/css/js. Why did the web win, and X not? The technologies used for the web (said html/css/js) are a mess. Combined with all the back-end-frameworks (Rails, Django and all) it really is a jungle to navigate thru. Still the web thrives with creativity and progress, while remote X apps do not.

  • Authentication settings in IIS Manager versus web.config versus system.serviceModel

    - by Joe
    I'm new to ASP.NET :) I have a WCF web service, and I want to use Basic authentication. I am getting lost in the authentication options: In IIS 6 Manager, I can go in to the properties of the web site and set authentication options. In the web site's web.config file, under system.web, there is an <authentication mode="Windows"/> tag In the web site's web.config file, under system.serviceModel, I can configure: <wsHttpBinding <binding name="MyBinding" <security mode="Transport" <transport clientCredentialType="Basic"/ </security </binding </wsHttpBinding What is the difference between these three? How should each be configured? Some context: I have a simple web site project that contains a single .svc web service, and I want it to use Basic authentication over SSL. (Also, I want it to not use Windows accounts, but maybe that is another question.)

  • Web service reference location?

    - by Damien Dennehy
    I have a Visual Studio 2008 solution that's currently consisting of three projects: A DataFactory project for Business Logic/Data Access. A Web project consisting of the actual user interface, pages, controls, etc. A Web.Core project consisting of utility classes, etc. The application requires consuming a web service. Normally I'd add the service reference to the Web project, but I'm not sure if this is best practice or not. The following options are open to me: Add the reference to the Web project. Add the reference to the Web.Core project, and create a wrapper method that Web will call to consume the web service. Add a new project called Web.Services, and copy step 2. This project is expected to increase in size so I'm open to any suggestions.

  • Implementing Multitasking on an iPhone/iOS4 Web App

    - by Peter Watts
    I am looking to build a web app that implements background audio and fast app switching. These features work out of the box, when run as regular Safari web pages, but as soon as you add the web-app-capable tag, and try to run in full screen mode, this functionality breaks. I did some testing and even the most basic web app will reload every time when you switch back to it. And seeing as it's a web app, we can't exactly implement the multitasking API. Has anyone found a work around? This isn't a deal-breaker, as you can just avoid full screen mode, but then you also lose the ability to use your own icon in the app switch tray. Perhaps this explains a lack of full screen mode in YouTube's new web app....

  • Compact web server with Lua support?

    - by OverTheRainbow
    Hello, I need to find a very compact, cross-platform web server that can run Lua scripts, ie. either a regular web server like Mongoose that will forward queries to a Lua program in eg. FastCGI, or a web server itself written in Lua which will save the need to provide a separate web server. I recently started learning about Lua so am still in the dark about what is available out there, save for the three I came accross: Barracuda Embedded Web Server http://barracudaserver.com/ba/doc/ Xavante - Lua HTTP 1.1 Web server http://keplerproject.github.com/xavante/ Haserl http://haserl.sourceforge.net/ If someone's already done this recently, what solution would you recommend along with any tutorial/article that would get me started? Thank you.

  • Web Applications Development: Security practices for Application design

    - by Shyam
    Hi, As I am creating more web applications that are targeted for multiple users, I figured out that I have to start thinking about user management and security. At a glance and in my ideal world, all users belong to a group. Permissions and access is thus defined per group (and inherited by the users of that group). Logically, I have my group of administrators, which are identified with a level "7" (integer) clearance. A group of webusers have for example level "1". This in generally all works great for me, but I need some kind of list that I have to keep in mind how I secure my system, and some general practices. I am not looking for a specific environment; I want to learn the why's and how's. An example is privilege escalation. If someone would be able to "push" themselves inside a group with higher privileges, for example the Administration, how can I prevent this, or what measures should I take to have some sort of precaution? I don't like in that case to walk into a caveat. My question is basically: where can I find a good resource, list, policy, book that explains the security of web applications, the why's, the how's and readable if you don't have any experience in the realm of advanced security? I prefer a free resource, as I believe I couldn't be the first one who thought about this. Thank you for your answers, comments and feedback.
