  • ODUG lands DotNetNuke guru Nik Kalyani as a speaker

    - by Brian Scarbeau
    If you are in the Orlando, FL area during the first week of May then you should head over to the Orlando DotNetNuke user group meeting. Nik Kalyani will be the speaker and you will learn a great deal from him. DotNetNuke Module Development with the MVP Pattern This session focuses on introducing attendees to the Model-View-Presenter pattern, support for which was recently introduced in the DotNetNuke Core. We'll start with a quick overview of the pattern, compare it to MVC, and then dive right into code. We will start with fundamentals and then develop a full-featured module using this pattern. In order to do justice to the pattern, we will use ASP.NET WebForms controls minimally and implement most of the UI using jQuery plug-ins. Finally, to increase audience participation (both present at the meeting and remote), we will use a hackathon-style model and allow anybody, anywhere to follow along with the presentation and code their own MVP-based solution that they can share online during or after the session. A URL with full instructions for the hackathon will be posted online a few days prior to the meeting. About Our Speaker Nik Kalyani is Co-founder and Strategic Advisor for DotNetNuke Corp., the company that manages the DotNetNuke Open Source project. Kalyani is also Founder and CEO of HyperCrunch. He is a technology entrepreneur with over 18 years of experience in the software industry. He is irrationally exuberant about technology, especially if it has anything to do with the Internet. HyperCrunch is his latest startup business that builds on his knowledge and experience from prior startups, two of them venture-funded. Kalyani is a creative tinkerer perpetually interested in looking around the corner and figuring out new and interesting ways to make the world a better place. An experienced web developer, he finds the business strategy and marketing aspects of the software business more exciting than writing code. When he does create software, his primary expertise is in creating products with compelling user experiences. Kalyani is most proficient with Microsoft technologies, but has no religious fanaticism about them. Kalyani has a bachelor’s degree in computer science from Western Michigan University. He is a frequent speaker at technology conferences and user group meetings. He lives in Mountain View, California with his wife and daughters. He blogs at http://www.kalyani.com and is @techbubble on Twitter.

  • "Build your own website" - Developing a CMS with Vague Requirements on a Tight Deadline

    - by walnutmon
    I'm a Java developer in charge of making a product which allows clients to "build their own site". I've spent a lot of time looking into Liferay, as I don't have any experience in building CMSs, and want to either use it, or get ideas of how to build a decent system. The time line is short, requirements are vague, yada yada Is Liferay a good technology to work with when showing the client (who may be very low on computer expertise) a user interface to build a site? The thing is, I want the power and flexibility to avoid the learning curve in building a CMS like product, but I don't want to waste time learning a new technology only to find its over-kill, or can't do the simple - but uncommon and unimplemented - things that we are asked to add as features Ideally I'd like to provide multiple web interfaces to the core API to build the sites - one that is very powerful, and another that is watered down and easy to use.

  • Introducing Glimpse – Firebug for your server

    - by Neil Davidson
    Here at Red Gate, we spend every waking hour trying to wow .NET and SQL developers with great products.  Every so often, though, we find something out in the wild which knocks our socks off by taking “ingeniously simple” to a whole new level.  That’s what a little community led by developers Nik Molnar and Anthony van der Hoorn has done with the open source tool Glimpse. Glimpse describes itself as ‘Firebug for the server.’  You drop the NuGet package into your ASP.NET project, and then — like magic* — your web pages will bare every detail of their execution.  Even by our high standards, it was trivial to get running: if you can use NuGet, you’re already there. You get all that lovely detail without changing any code. Our feelings go beyond respect for the developers who designed and wrote Glimpse; we’re thrilled that Nik and Anthony have come to work for Red Gate full-time. They’re going to stay in control of the project and keep doing open source development work on Glimpse.  In the medium term, we’re hoping to make paid-for products which plug into the free open source framework, especially in areas like performance profiling where we already have some deep technology.  First, though, Glimpse needs to get from beta to a v1. Given the breakneck pace of new development, this should only be a month or so away. Supporting an open source project is a first for Red Gate, so we’re going to be working with Nik and Anthony, with the Glimpse community and even with other vendors to figure out what ‘great’ looks like from the a user perspective.  Only one thing is certain: this technology deserves a wider audience than the 40,000 people who have already downloaded it, so please have a look and tell us what you think. You can hear more about what the Glimpse developers think on the Glimpse blog, and there are plenty more technical facts over at our product manager’s blog. If you have any questions or queries, please tweet with the #glimpse hashtag or contact the Glimpse team directly on [email protected]. [*That’s ”magic” in the Arthur C. Clarke “sufficiently advanced technology” sense, of course] Neil Davidson co-founder and Joint CEO Red Gate Software http://twitter.com/neildavidson

  • 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.

  • Import and Export data from SQL Server 2005 to XL Sheet

    - by SAMIR BHOGAYTA
    For uploading the data from Excel Sheet to SQL Server and viceversa, we need to create a linked server in SQL Server. Expample linked server creation: Before you executing the below command the excel sheet should be created in the specified path and it should contain the name of the columns. EXEC sp_addlinkedserver 'ExcelSource2', 'Jet 4.0', 'Microsoft.Jet.OLEDB.4.0', 'C:\Srinivas\Vdirectory\Testing\Marks.xls', NULL, 'Excel 5.0' Once you executed above query it will crate linked server in SQL Server 2005. The following are the Query from sending the data from Excel sheet to SQL Server 2005. INSERT INTO emp SELECT * from OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=C:\text.xls','SELECT * FROM [sheet1$]') The following query is for sending the data from SQL Server 2005 to Excel Sheet. insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=c:\text.xls;', 'SELECT * FROM [sheet1$]') select * from emp

  • 2 Birds, 1 Stone: Enabling M2M and Mobility in Healthcare

    - by Eric Jensen
    Jim Connors has created a video showcase of a comprehensive healthcare solution, connecting a mobile application directly to an embedded patient monitoring system. In the demo, Jim illustrates how you can easily build solutions on top of the Java embedded platform, using Oracle products like Berkeley DB and Database Mobile Server. Jim is running Apache Tomcat on an embedded device, using Berkeley DB as the data store. BDB is transparently linked to an Oracle Database backend using  Database Mobile Server. Information protection is important in healthcare, so it is worth pointing out that these products offer strong data encryption, for storage as well as transit. In his video, Jim does a great job of demystifying M2M. What's compelling about this demo is that uses a solution architecture that enterprise developers are already comfortable and familiar with: a Java apps server with a database backend. The additional pieces used to embed this solution are Oracle Berkeley DB and Database Mobile Server. It functions transparently, from the perspective of Java apps developers. This means that organizations who understand Java apps (basically everyone) can use this technology to develop embedded M2M products. The potential uses for this technology in healthcare alone are immense; any device that measures and records some aspect of the patient could be linked, securely and directly, to the medical records database. Breathing, circulation, other vitals, sensory perception, blood tests, x-rats or CAT scans. The list goes on and on. In this demo case, it's a testament to the power of the Java embedded platform that they are able to easily interface the device, called a Pulse Oximeter, with the web application. If Jim had stopped there, it would've been a cool demo. But he didn't; he actually saved the most awesome part for the end! At 9:52 Jim drops a bombshell: He's also created an Android app, something a doctor would use to view patient health data from his mobile device. The mobile app is seamlessly integrated into the rest of the system, using the device agent from Oracle's Database Mobile Server. In doing so, Jim has really showcased the full power of this solution: the ability to build M2M solutions that integrate seamlessly with mobile applications. In closing, I want to point out that this is not a hypothetical demo using beta or even v1.0 products. Everything in Jim's demo is available today. What's more, every product shown is mature, and already in production at many customer sites, albeit not in the innovative combination Jim has come up with. If your customers are in the market for these type of solutions (and they almost certainly are) I encourage you to download the components and try it out yourself! All the Oracle products showcased in this video are available for evaluation download via Oracle Technology Network.
