  • Update Metadata and Cover Art in Windows Media Player 12

    - by DigitalGeekery
    If you use Windows Media Player 12 in Windows 7, you may notice some of your media is missing information when displayed in the library. Today we look at how to edit and update metadata and cover art in WMP 12. By default, Windows Media Player will pull metadata, such as the title, artist, album, and cover art from the Internet. If you did not accept that default option during setup, we’ll need to turn the feature on first. Select Tools > Options from the top Menu bar. On the Library tab, ensure that Retrieve additional information form the Internet is checked. Click OK. Editing Metadata Now we’re ready to update some files. Find a media file with incorrect details or cover art. Right-click on the title and select Find album info. This will bring up the Find album information window. Here you’ll see the existing information that Windows Media Player interpreted as correct on the left side. The results of  WMP’s search for the media information are on the right. Click on Artists,  Albums , or Tracks to scroll through the search results and try to find a match. You can also type in new keywords in the Search box and hit enter (or click the Search button) to perform a new search.   If you find a correct match for your media file, click to select it and click Next. You’ll be prompted to confirm your selection, then click Finish. You should now see your media file displayed properly in Windows Media Player. Manually Entering Metadata If your search for the correct media information comes up empty, you can always manually enter the information yourself. On the Find album information window, click Edit under Existing Information. You can edit the existing information in the text boxes or the Genre dropdown box. There are a couple hidden text boxes below. Click next to Contributing Artist or Composer to enter that information.   Choosing Your Own Cover Art If your media file doesn’t pull the proper cover art, or if you simply wish to find a different image, you can add your own. Search online for a suitable image. An ideal size would be around 300 x 300 pixels, give or take. Right-click on the image copy the image. You’ll need to switch to Expanded title (if you haven’t already) to paste the image.   Paste your new image by right-clicking on the current image and select Paste album art. Note: If the image is not suitable size or type, the Paste album art option will not be available. Your new cover art will appear in Windows Media Player.   Even though it is pulled from the Internet, cover art is cached on your computer and will still be available when you are disconnected from the Internet.

  • Travelling MVP #1: Visit to SharePoint User Group Finland

    - by DigiMortal
    My first self organized trip this autumn was visit to SharePoint User Group Finland community evening. As active community leaders who make things like these possible they are worth mentioning and on spug.fi side there was Jussi Roine the one who invited me. Here is my short review about my trip to Helsinki. User group meeting As Helsinki is near Tallinn I went there using ship. It was easy to get from sea port to venue and I had also some minutes of time to visit academic book store. Community evening was held on the ground floor of one city center hotel and room was conveniently located near hotel bar and restaurant. Here is the meeting schedule: Welcome (Jussi Roine) OpenText application archiving and governance for SharePoint (Bernd Hennicke, OpenText) Using advanced C# features in SharePoint development (Alexey Sadomov, NED Consulting) Optimizing public-facing internet sites for SharePoint (Gunnar Peipman) After meeting, of course, local dudes doesn’t walk away but continue with some beers and discussion. Sessions After welcome words by Jussi there was session by Bernd Hennicke who spoke about OpenText. His session covered OpenText history and current moment. After this introduction he spoke about OpenText products for SharePoint and gave the audience good overview about where their SharePoint extensions fit in big picture. I usually don’t like those vendors sessions but this one was good. I mean vendor dudes were not aggressively selling something. They were way different – kind people who introduced their stuff and later answered questions. They acted like good guests. Second speaker was Alexey Sadomov who is working on SharePoint development projects. He introduced some ways how to get over some limitations of SharePoint. I don’t go here deeply with his session but it’s worth to mention that this session was strong one. It is not rear case when developers have to make nasty hacks to SharePoint. I mean really nasty hacks. Often these hacks are long blocks of code that uses terrible techniques to achieve the result. Alexey introduced some very much civilized ways about how to apply hacks. Alex Sadomov, SharePoint MVP, speaking about SharePoint coding tips and tricks on C# I spoke about how I optimized caching of Estonian Microsoft community portal that runs on SharePoint Server and that uses publishing infrastructure. I made no actual demos on SharePoint because I wanted to focus on optimizing process and share some experiences about how to get caches optimized and how to measure caches. Networking After official part there was time to talk and discuss with people. Finns are cool – they have beers and they are glad. It was not big community event but people were like one good family. Developers there work often for big companies and it was very interesting to me to hear about their experiences with SharePoint. One thing was a little bit surprising for me – SharePoint guys in Finland are talking actively also about Office 365 and online SharePoint. It doesn’t happen often here in Estonia. I had to leave a little bit 21:00 to get to my ship back to Tallinn. I am sure spug.fi dudes continued nice evening and they had at least same good time as I did. Do I want to go back to Finland and meet these guys again? Yes, sure, let’s do it again! :)

  • I’m a Phoenix… and I’m miffed

    - by Stan Spotts
    For personal reasons, almost 30 years ago I left school to enter the workforce. I decided late 2008 to go back to school and finish my degree. After the expected loss of credits for a transfer, from Temple University to University of Phoenix, I'm now about 75% done. The experience has been interesting. Classes are time compressed, only 5 weeks each. Because I have a family and a full time job, I'm taking one at a time. Even so, I've written more papers in these classes than I ever wrote at Temple. My own papers are one thing, but the team papers give me heartburn since I can't completely control what goes into them. Not a big deal except that they make up 30% of our grade. In any case, most of the class facilitators have been great. I had great ones for Accounting, Finance, and frankly most others. I've had a few (4, maybe) cases where I was less than 2 points from an A, and asked the facilitator if I could get any of my work reviewed to see if I could get those extra points. I figured it was worth a shot, and there were no extenuating circumstances to help make my case. I think that only one facilitator decided after a review of one paper that my interpretation was good, just not what he expected, and gave me another point, which gave me an A. So while none are pushovers, they've all been open to discussion, which is as much as I should expect. Overall, good experience. That is, until my last class. On the second week, the day I was due to hand in my personal assignment for the week, I was in an accident. An SUV creamed my little Ford Focus, and totaled it (estimated repair over $11K). I was pretty banged up, especially my left shoulder. I was scheduled for rotator cuff surgery for two weeks later, and getting hit against the door really made it worse. After dealing with the police, the EMT, the tow truck, and the Percocet and Flexeril for the pain, I crashed for the night and didn't get to upload my paper until the next day. The instructor took 30% off for it being late, even after I supplied photos of the car, my arm (huge bruises), and offered to supply the police report number. I figured I'd be okay since that's 2.7 points, and I could lose up to 5 before jeopardizing an A grade. Well, that wasn't the case as we lost more points than I expected on our team paper in Week 5. I ended up with a 94.3. Yes, 7/10 of a point from an A. Of course I asked the instructor to review the issue with the accident and give me just the 0.7 points I needed for the A. That got me a short response of "I have received your emails and review your work over the last five weeks. Your current grade will stand. If you would like to dispute your grade then please feel free to contact your academic advisor. I wish you much success in your professional and academic career." Brrrr….! So I asked my academic advisor to file a dispute. If it wasn't that a pretty bad car accident was the cause, I wouldn't have. Without the grade reduction, I would have had a 97 for the class, so I'll argue that I was performing at the A level throughout the class. Why her purported "review" of my work didn't then warrant such a minor adjustment, I don't know. An A- drops my GPA, and this ticked me off. Now I have to wait and see what the school says about the grade dispute.

  • How to configure Visual Studio 2010 code coverage for ASP.NET MVC unit tests

    - by DigiMortal
    I just got Visual Studio 2010 code coverage work with ASP.NET MVC application unit tests. Everything is simple after you have spent some time with forums, blogs and Google. To save your valuable time I wrote this posting to guide you through the process of making code coverage work with ASP.NET MVC application unit tests. After some fighting with Visual Studio I got everything to work as expected. I am still not very sure why users must deal with this mess, but okay – I survived it. Before you start configuring Visual Studio I expect your solution meets the following needs: there are at least one library that will be tested, there is at least on library that contains tests to be run, there are some classes and some tests for them, and, of course, you are using version of Visual Studio 2010 that supports tests (I have Visual Studio 2010 Ultimate). Now open the following screenshot to separate windows and follow the steps given below. Visual Studio 2010 Test Settings window. Click on image to see it at original size.  Double click on Local.testsettings under Solution Items. Test settings window will be opened. Select “Data and Diagnostics” from left pane. Mark checkboxes “ASP.NET Profiler” and “Code Coverage”. Move cursor to “Code Coverage” line and press Configure button or make double click on line. Assemblies selection window will be opened. Mark checkboxes that are located before assemblies about what you want code coverage reports and apply settings. Save your project and close Visual Studio. Run Visual Studio as Administrator and run tests. NB! Select Test => Run => Tests in Current Context from menu. When tests are run you can open code coverage results by selecting Test => Windows => Code Coverage Results from menu. Here you can see my example test results. Visual Studio 2010 Test Results window. All my tests passed this time. :) Click on image to see it at original size.  And here are the code coverage results. Visual Studio 2101 Code Coverage Results. I need a lot more tests for sure. Click on image to see it at original size.  As you can see everything was pretty simple. But it took me sometime to figure out how to get everything work as expected. Problems? You may face some problems when making code coverage work. Here is my short list of possible problems. Make sure you have all assemblies available for code coverage. In some cases it needs more libraries to be referenced as you currently have. By example, I had to add some more Enterprise Library assemblies to my project. You can use EventViewer to discover errors that where given during testing. Make sure you selected all testable assemblies from Code Coverage settings like shown above. Otherwise you may get empty results. Tests with code coverage are slower because we need ASP.NET profiler. If your machine slows down then try to free more resources.

  • JavaScript Browser Hacks

    Recently during one of my client side scripting classes, I was trying to show my students some basic examples of JavaScript as an introduction to the language.  My first basic example was to show an alert box using JavaScript via the address bar. The student’s reaction to my browser hack example really caught me off guard in a good way. After programming with a language for close to 10 years you start to lose the "Awe Cool!" effect that new learners of a language experience when writing code. New learns of JavaScript are the reason why I created this post. Please enjoy. Note: Place JavaScript in to address bar and then press the enter key. Example 1: JavaScript Alert box displaying My name: John Doe Javascript:alert('My name: \n John Doe') ; Example 2: JavaScript alert box displaying name entered by user. javascript:alert('My name: \n ' + prompt('Enter Name','Name')) ; Example 3: JavaScript alert box displaying name entered by user, and then displays the length of the name. javascript:var name= prompt('Enter Name','Name'); alert('My name: \n ' + name); alert(name.length); If you notice, the address bar will execute JavaScript on the current page loaded in the browser using the Document Object Model (DOM). Additionally, the address bar will allow multiple lines to be executed sequentially even though all of the code is contained within one line due to the fact that the JavaScript interpreter uses the “;” to indicate where a line of ends and a new one begins. After doing a little more research on the topic of JavaScript Browser Hacks I found a few other cool JavaScript hacks which I will list below. Example 4: Make any webpage editableSource: http://www.openjason.com/2008/09/02/browser-hack-make-any-web-page-editable/ javascript:document.body.contentEditable='true'; document.designMode='on'; void 0; Example 5: CHINESE DRAGON DANCING Source: http://nzeyi.wordpress.com/2009/06/01/dwrajaxjavascript-hacks-the-secrets-of-javascript-in-the-adress-bar/ javascript:R=0;x1=0.1;y1=0.05;x2=0.25;y2=0.24;x3=1.6; y3=0.24;x4=300;y4=200;x5=300;y5=200;DI=document.links; DIL=DI.length;A=function(){for(i=0;i-DIL;i++){DI[i].style. position='absolute';DI[i].style.left=Math.sin(R*x1+i*x2+x3)*x4+ x5;DI[i].style.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++;}; setInterval('A()',5);void(0); Example 6: Reveal content stored in password protected fields javascript:(function(){var s,F,j,f,i; s = “”; F = document.forms; for(j=0; j Example 7: Force user to close browser windowSource: http://forums.digitalpoint.com/showthread.php?t=767053 javascript:while(1){alert('Restart your brower to close this box!')} Learn more about JavaScript Browser Hacks.

  • Logging WebSocket Frames using Chrome Developer Tools, Net-internals and Wireshark (TOTD #184)

    - by arungupta
    TOTD #183 explained how to build a WebSocket-driven application using GlassFish 4. This Tip Of The Day (TOTD) will explain how do view/debug on-the-wire messages, or frames as they are called in WebSocket parlance, over this upgraded connection. This blog will use the application built in TOTD #183. First of all, make sure you are using a browser that supports WebSocket. If you recall from TOTD #183 then WebSocket is combination of Protocol and JavaScript API. A browser supporting WebSocket, or not, means they understand your web pages with the WebSocket JavaScript. caniuse.com/websockets provide a current status of WebSocket support in different browsers. Most of the major browsers such as Chrome, Firefox, Safari already support WebSocket for the past few versions. As of this writing, IE still does not support WebSocket however its planned for a future release. Viewing WebSocket farmes require special settings because all the communication happens over an upgraded HTTP connection over a single TCP connection. If you are building your application using Java, then there are two common ways to debug WebSocket messages today. Other language libraries provide different mechanisms to log the messages. Lets get started! Chrome Developer Tools provide information about the initial handshake only. This can be viewed in the Network tab and selecting the endpoint hosting the WebSocket endpoint. You can also click on "WebSockets" on the bottom-right to show only the WebSocket endpoints. Click on "Frames" in the right panel to view the actual frames being exchanged between the client and server. The frames are not refreshed when new messages are sent or received. You need to refresh the panel by clicking on the endpoint again. To see more detailed information about the WebSocket frames, you need to type "chrome://net-internals" in a new tab. Click on "Sockets" in the left navigation bar and then on "View live sockets" to see the page. Select the box with the address to your WebSocket endpoint and see some basic information about connection and bytes exchanged between the client and the endpoint. Clicking on the blue text "source dependency ..." shows more details about the handshake. If you are interested in viewing the exact payload of WebSocket messages then you need a network sniffer. These tools are used to snoop network traffic and provide a lot more details about the raw messages exchanged over the network. However because they provide lot more information so they need to be configured in order to view the relevant information. Wireshark (nee Ethereal) is a pretty standard tool for sniffing network traffic and will be used here. For this blog purpose, we'll assume that the WebSocket endpoint is hosted on the local machine. These tools do allow to sniff traffic across the network though. Wireshark is quite a comprehensive tool and we'll capture traffic on the loopback address. Start wireshark, select "loopback" and click on "Start". By default, all traffic information on the loopback address is displayed. That includes tons of TCP protocol messages, applications running on your local machines (like GlassFish or Dropbox on mine), and many others. Specify "http" as the filter in the top-left. Invoke the application built in TOTD #183 and click on "Say Hello" button once. The output in wireshark looks like Here is a description of the messages exchanged: Message #4: Initial HTTP request of the JSP page Message #6: Response returning the JSP page Message #16: HTTP Upgrade request Message #18: Upgrade request accepted Message #20: Request favicon Message #22: Responding with favicon not found Message #24: Browser making a WebSocket request to the endpoint Message #26: WebSocket endpoint responding back You can also use Fiddler to debug your WebSocket messages. How are you viewing your WebSocket messages ? Here are some references for you: JSR 356: Java API for WebSocket - Specification (Early Draft) and Implementation (already integrated in GlassFish 4 promoted builds) TOTD #183 - Getting Started with WebSocket in GlassFish Subsequent blogs will discuss the following topics (not necessary in that order) ... Binary data as payload Custom payloads using encoder/decoder Error handling Interface-driven WebSocket endpoint Java client API Client and Server configuration Security Subprotocols Extensions Other topics from the API

  • BizTalk Cross Reference Data Management Strategy

    - by charlie.mott
    Article Source: http://geekswithblogs.net/charliemott This article describes an approach to the management of cross reference data for BizTalk.  Some articles about the BizTalk Cross Referencing features can be found here: http://home.comcast.net/~sdwoodgate/xrefseed.zip http://geekswithblogs.net/michaelstephenson/archive/2006/12/24/101995.aspx http://geekswithblogs.net/charliemott/archive/2009/04/20/value-vs.id-cross-referencing-in-biztalk.aspx Options Current options to managing this data include: Maintaining xml files in the format that can be used by the out-of-the-box BTSXRefImport.exe utility. Use of user interfaces that have been developed to manage this data: BizTalk Cross Referencing Tool XRef XML Creation Tool However, there are the following issues with the above options: The 'BizTalk Cross Referencing Tool' requires a separate database to manage.  The 'XRef XML Creation' tool has no means of persisting the data settings. The 'BizTalk Cross Referencing tool' generates integers in the common id field. I prefer to use a string (e.g. acme.country.uk). This is more readable. (see naming conventions below). Both UI tools continue to use BTSXRefImport.exe.  This utility replaces all xref data. This can be a problem in continuous integration environments that support multiple clients or BizTalk target instances.  If you upload the data for one client it would destroy the data for another client.  Yet in TFS where builds run concurrently, this would break unit tests. Alternative Approach In response to these issues, I instead use simple SQL scripts to directly populate the BizTalkMgmtDb xref tables combined with a data namepacing strategy to isolate client data. Naming Conventions All data keys use namespace prefixing.  The pattern will be <companyName>.<data Type>.  The naming conventions will be to use lower casing for all items.  The data must follow this pattern to isolate it from other company cross-reference data.  The table below shows some sample data. (Note: this data uses the 'ID' cross-reference tables.  the same principles apply for the 'value' cross-referencing tables). Table.Field Description Sample Data xref_AppType.appType Application Types acme.erp acme.portal acme.assetmanagement xref_AppInstance.appInstance Application Instances (each will have a corresponding application type). acme.dynamics.ax acme.dynamics.crm acme.sharepoint acme.maximo xref_IDXRef.idXRef Holds the cross reference data types. acme.taxcode acme.country xref_IDXRefData.CommonID Holds each cross reference type value used by the canonical schemas. acme.vatcode.exmpt acme.vatcode.std acme.country.usa acme.country.uk xref_IDXRefData.AppID This holds the value for each application instance and each xref type. GBP USD SQL Scripts The data to be stored in the BizTalkMgmtDb xref tables will be managed by SQL scripts stored in a database project in the visual studio solution. File(s) Description Build.cmd A sqlcmd script to deploy data by running the SQL scripts below.  (This can be run as part of the MSBuild process).   acme.purgexref.sql SQL script to clear acme.* data from the xref tables.  As such, this will not impact data for any other company. acme.applicationInstances.sql   SQL script to insert application type and application instance data.   acme.vatcode.sql acme.country.sql etc ...  There will be a separate SQL script to insert each cross-reference data type and application specific values for these types.

  • Clean Code: A Handbook of Agile Software Craftsmanship – book review

    - by DigiMortal
       Writing code that is easy read and test is not something that is easy to achieve. Unfortunately there are still way too much programming students who write awful spaghetti after graduating. But there is one really good book that helps you raise your code to new level – your code will be also communication tool for you and your fellow programmers. “Clean Code: A Handbook of Agile Software Craftsmanship” by Robert C. Martin is excellent book that helps you start writing the easily readable code. Of course, you are the one who has to learn and practice but using this book you have very good guide that keeps you going to right direction. You can start writing better code while you read this book and you can do it right in your current projects – you don’t have to create new guestbook or some other simple application to start practicing. Take the project you are working on and start making it better! My special thanks to Robert C. Martin I want to say my special thanks to Robert C. Martin for this book. There are many books that teach you different stuff and usually you have markable learning curve to go before you start getting results. There are many books that show you the direction to go and then leave you alone figuring out how to achieve all that stuff you just read about. Clean Code gives you a lot more – the mental tools to use so you can go your way to clean code being sure you will be soon there. I am reading books as much as I have time for it. Clean Code is top-level book for developers who have to write working code. Before anything else take Clean Code and read it. You will never regret your decision. I promise. Fragment of editorial review “Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees.

  • MongoDB usage best practices

    - by andresv
    The project I'm working on uses MongoDB for some stuff so I'm creating some documents to help developers speedup the learning curve and also avoid mistakes and help them write clean & reliable code. This is my first version of it, so I'm pretty sure I will be adding more stuff to it, so stay tuned! C# Official driver notes The 10gen official MongoDB driver should always be referenced in projects by using NUGET. Do not manually download and reference assemblies in any project. C# driver quickstart guide: http://www.mongodb.org/display/DOCS/CSharp+Driver+Quickstart Reference links C# Language Center: http://www.mongodb.org/display/DOCS/CSharp+Language+Center MongoDB Server Documentation: http://www.mongodb.org/display/DOCS/Home MongoDB Server Downloads: http://www.mongodb.org/downloads MongoDB client drivers download: http://www.mongodb.org/display/DOCS/Drivers MongoDB Community content: http://www.mongodb.org/display/DOCS/CSharp+Community+Projects Tutorials Tutorial MongoDB con ASP.NET MVC - Ejemplo Práctico (Spanish):http://geeks.ms/blogs/gperez/archive/2011/12/02/tutorial-mongodb-con-asp-net-mvc-ejemplo-pr-225-ctico.aspx MongoDB and C#:http://www.codeproject.com/Articles/87757/MongoDB-and-C C# driver LINQ tutorial:http://www.mongodb.org/display/DOCS/CSharp+Driver+LINQ+Tutorial C# driver reference: http://www.mongodb.org/display/DOCS/CSharp+Driver+Tutorial Safe Mode Connection The C# driver supports two connection modes: safe and unsafe. Safe connection mode (only applies to methods that modify data in a database like Inserts, Deletes and Updates. While the current driver defaults to unsafe mode (safeMode == false) it's recommended to always enable safe mode, and force unsafe mode on specific things we know aren't critical. When safe mode is enabled, the driver internal code calls the MongoDB "getLastError" function to ensure the last operation is completed before returning control the the caller. For more information on using safe mode and their implicancies on performance and data reliability see: http://www.mongodb.org/display/DOCS/getLastError+Command If safe mode is not enabled, all data modification calls to the database are executed asynchronously (fire & forget) without waiting for the result of the operation. This mode could be useful for creating / updating non-critical data like performance counters, usage logging and so on. It's important to know that not using safe mode implies that data loss can occur without any notification to the caller. As with any wait operation, enabling safe mode also implies dealing with timeouts. For more information about C# driver safe mode configuration see: http://www.mongodb.org/display/DOCS/CSharp+getLastError+and+SafeMode The safe mode configuration can be specified at different levels: Connection string: mongodb://hostname/?safe=true Database: when obtaining a database instance using the server.GetDatabase(name, safeMode) method Collection: when obtaining a collection instance using the database.GetCollection(name, safeMode) method Operation: for example, when executing the collection.Insert(document, safeMode) method Some useful SafeMode article: http://stackoverflow.com/questions/4604868/mongodb-c-sharp-safemode-official-driver Exception Handling The driver ensures that an exception will be thrown in case of something going wrong, in case of using safe mode (as said above, when not using safe mode no exception will be thrown no matter what the outcome of the operation is). As explained here https://groups.google.com/forum/?fromgroups#!topic/mongodb-user/mS6jIq5FUiM there is no need to check for any returned value from a driver method inserting data. With updates the situation is similar to any other relational database: if an update command doesn't affect any records, the call will suceed anyway (no exception thrown) and you manually have to check for something like "records affected". For MongoDB, an Update operation will return an instance of the "SafeModeResult" class, and you can verify the "DocumentsAffected" property to ensure the intended document was indeed updated. Note: Please remember that an Update method might return a null instance instead of an "SafeModeResult" instance when safe mode is not enabled.

  • If You Could Cut Your Meeting Times in ½ Would You?

    - by [email protected]
    By Brian Dayton on April 22, 2010 2:02 PM I know it sounds like a big promise. And what I'm thinking about may not cut a :60 minute meeting into :30 minutes, but it could make meetings and interactions up to 2X more productive. How? Social Media for the Enterprise, Not Social Media In the Enterprise Bear with me. I'm not talking about whether or not workers should or shouldn't have access to Facebook on corporate networks. That topic has been discussed @ length. I'm also not talking about the direct benefits of Social Networking tools like Presence (the ability to see someone online and ask a question in real-time), blogs, RSS feeds or external tools like Twitter. The Un-Measurable Benefits Would you do something that you believe will have a positive effect--but can't be measured? It's impossible to quantify the effectiveness of a meeting. However, what I am talking about would be more of a byproduct of all of the social networking tools above. Here's the hypothesis: As I've gotten more and more busy with work, family, travel and kids--and the same has happened to my friends and family--I'm less and less connected. But by introducing Facebook to my life I've not only made connections with longtime friends whom I haven't spoken to in years--but I've increased the pace and quality of interactions, on and offline, with close friends who I see and speak to every week. In some cases it even enhances the connections and interactions with those I see or speak to every day. The same holds true in an organization. Especially a larger one with highly matrixed organizational structures. You work with people on a project, new people come in with each different project and a disproportionate amount of time is spent getting oriented and staying current. Going back to the initial value proposition--making meetings shorter/more effective--a large amount of time is spent: - At Project Kick-off: Meeting and understanding team member's histories, goals & roles - Ongoing: Summarizing events since the last meeting or update email In my personal, Facebook life today I know that: - My best friend from college - has been stranded in India for 5 days because of the volcano in Iceland and is now only 250 miles from home - One of my co-workers started conference calls at 6:30 this morning - My wife wasn't terribly pleased with my painting skills in our new bathroom (disclosure: she told me this face to face too) Strengthening Weak Links A recent article in CIO Magazine, Three Dangerous Social Media Misconceptions (Kristen Burnham, March 12, 2010) calls out the #1 misconception as follows: 1. "Face-to-face relationships are far more valuable than virtual ones." While some level of physical interaction will always add value to relationships, Gartner says that come 2020, most relationships and teams will be based on "weak links"--that is, you may not have personally met a contact, but you'll know of or may have interacted with him via social sites like Facebook, LinkedIn and Twitter. The sooner your enterprise adopts these tools, the sooner your employees will learn them, and the sooner you'll begin to cultivate these relationships-of-the-future. I personally believe that it's not an either/or choice between face-to-face and virtual interactions. In fact, I'll be as bold as saying it doesn't matter. I can point to two extremely valuable work relationships that I've had over the past 5 years: - I shared an office with one of them - I met the other person, face-to-face, only once Both relationships were very productive. The dynamics were similar. The communication tactics differed immensely. What does matter is the quality, frequency and relevance of interactions. Still sound like too much? An over-promise? Stay tuned for my next post The Gap Between Facebook and LinkedIn. I'll also connect some of the dots with where Oracle Applications and technologies are headed.

  • POP Forums v9 Beta 1 for ASP.NET MVC 3 posted to CodePlex!

    - by Jeff
    As promised, I posted a beta build of my forum app for ASP.NET MVC 3. Get the new goodies here: http://popforums.codeplex.com/releases/view/58228 This is the first beta for the ASP.NET MVC 3 version of POP Forums. It is nearly feature complete, and ready for testing and feedback. For previous release notes, look here, here and here.Check out the live preview: http://preview.popforums.com/ForumsSetup instructions are on the home page of this project. The new hotness in the beta, or what has been done since the last preview: All views converted to use Razor E-mail subscription/notification of new posts New post indicators/mark read buttons Permalinks to posts Jump to newest post (from new post indicators) Recent topics Favorite topics Moderator functions for topics (pin/close/delete, plus move and rename) Search, ported from v8. Not a ton of optimization here, or new unit testing, but the old version worked pretty well User posts (topics the user posted in) Forgot password Vanity items (signatures and avatars) Hide vanity items per user preference Some minor data caching where appropriate A little bit of UI refinement Lots-o-bug fixes Lots-o-unit tests What's next? The plan between now and the next beta is as follows: Continue working through features/tasks, and fix bugs as they're reported Integrate the forum into a real, production site Refine the UI Refactor as much as possible... the code organization is not entirely logical in some places After the second beta, a release candidate will follow, with a real "final" release after that. Subsequent releases should come relatively frequently and without a lot of risk. The trick in building this thing has been that it mostly tossed the previous WebForms version, which was all full of crusties. The time table for this is a little harder to pin down, as day jobs and families will have their effect. Other notes Refactoring will be a priority. As the features of MVC have evolved, so have my desires to use it in a fashion that makes things clear and easy to follow. I don't even know if anyone will ever start mucking around in the code, but on the off chance they do, I'd like what they find to not suck. Other nice-to-haves are builds to target Windows Azure and SQL CE. A nice setup UI would be super too. I think the ASP.NET MVC world has gone long enough without a decent forum.The biggest challenge that I've found is making the forum something that can be dropped in any app. While it does rope its views into an area, areas are mostly just routing details. I haven't thought of a clever way yet to limit dependency injection, for example, to just the forum bits. I mean, everyone should be using Ninject, but how realistic is that? ;)How much time and effort should you spend on POP Forums in its current state? Change is inevitable, but at this point I'm reasonably committed to not changing the database schema. I really think it will stay as-is. All bets are off for the various interfaces throughout the app, but the data should generally resist change. It's not even that different from v8, which was one of the original goals because I didn't want to rewrite SQL or introduce a new ORM or whatever. My point is that if you wanted to build a site around this today, even though it's not entirely functional, I think it's low risk in terms of data loss. I can't vouch for whether or not you know what you're doing.I've been having some chats with people lately about quoting posts, and honestly there has to be something better and straight forward. That continues to be a holy grail of mine, and some day, I hope to find it.Enjoy... it's starting to feel more real every day!

  • IntelliTrace As a Learning Tool for MVC2 in a VS2010 Project

    - by Sam Abraham
    IntelliTrace is a new feature in Visual Studio 2010 Ultimate Edition. I see this valuable tool as a “Program Execution Recorder” that captures information about events and calls taking place as soon as we hit the VS2010 play (Start Debugging) button or the F5 key. Many online resources already discuss IntelliTrace and the benefit it brings to both developers and testers alike so I see no value of just repeating this information.  In this brief blog entry, I would like to share with you how I will be using IntelliTrace in my upcoming talk at the Ft Lauderdale ArcSig .Net User Group Meeting on April 20th 2010 (check http://www.fladotnet.com for more information), as a learning tool to demonstrate the internals of the lifecycle of an MVC2 application.  I will also be providing some helpful links that cover IntelliTrace in more detail at the end of my article for reference. IntelliTrace is setup by default to only capture execution events. Microsoft did such a great job on optimizing its recording process that I haven’t even felt the slightest performance hit with IntelliTrace running as I was debugging my solutions and projects.  For my purposes here however, I needed to capture more information beyond execution events, so I turned on the option for capturing calls in addition to events as shown in Figures 1 and 2. Changing capture options will require us to stop our debugging session and start over for the new settings to take place. Figure 1 – Access IntelliTrace options via the Tools->Options menu items Figure 2 – Change IntelliTrace Options to capture call information as well as events Notice the warning with regards to potentially degrading performance when selecting to capture call information in addition to the default events-only setting. I have found this warning to be sure true. My subsequent tests showed slowness in page load times compared to rendering those same exact pages with the “event-only” option selected. Execution recording is auto-started along with the new debugging session of our project. At this point, we can simply interact with the application and continue executing normally until we decide to “playback” the code we have executed so far.  For code replay, first step is to “break” the current execution as show in Figure 3.   Figure 3 – Break to replay recording A few tries later, I found a good process to quickly find and demonstrate the MVC2 page lifecycle. First-off, we start with the event view as shown in Figure 4 until we find an interesting event that needs further studying.  Figure 4 – Going through IntelliTrace’s events and picking as specific entry of interest We now can, for instance, study how the highlighted HTTP GET request is being handled, by clicking on the “Calls View” for that particular event. Notice that IntelliTrace shows us all calls that took place in servicing that GET request. Double clicking on any call takes us to a more granular view of the call stack within that clicked call, up until getting to a specific line of code where we can do a line-by-line replay of the execution from that point onwards using F10 or F11 just like our typical good old VS2008 debugging helped us accomplish. Figure 5 – switching to call view on an event of interest Figure 6 – Double clicking on call shows a more granular view of the call stack. In conclusion, the introduction of IntelliTrace as a new addition to the VS developers’ tool arsenal enhances development and debugging experience and effectively tackles the “no-repro” problem. It will also hopefully enhance my audience’s experience listening to me speaking about  an MVC2 page lifecycle which I can now easily visually demonstrate, thereby improving the probability of keeping everybody awake a little longer.

  • Fusion Concepts: Fusion Database Schemas

    - by Vik Kumar
    You often read about FUSION and FUSION_RUNTIME users while dealing with Fusion Applications. There is one more called FUSION_DYNAMIC. Here are some details on the difference between these three and the purpose of each type of schema. FUSION: It can be considered as an Administrator of the Fusion Applications with all the corresponding rights and powers such as owning tables and objects, providing grants to FUSION_RUNTIME.  It is used for patching and has grants to many internal DBMS functions. FUSION_RUNTIME: Used to run the Applications.  Contains no DB objects. FUSION_DYNAMIC: This schema owns the objects that are created dynamically through ADM_DDL. ADM_DDL is a package that acts as a wrapper around the DDL statement. ADM_DDL support operations like truncate table, create index etc. As the above statements indicate that FUSION owns the tables and objects including FND tables so using FUSION to run applications is insecure. It would be possible to modify security policies and other key information in the base tables (like FND) to break the Fusion Applications security via SQL injection etc. Other possibilities would be to write a logon DB trigger and steal credentials etc. Thus, to make Fusion Applications secure FUSION_RUNTIME is granted privileges to execute DMLs only on APPS tables. Another benefit of having separate users is achieving Separation of Duties (SODs) at schema level which is required by auditors. Below are the roles and privileges assigned to FUSION, FUSION_RUNTIME and FUSION_DYNAMIC schema: FUSION It has the following privileges: Create SESSION Do all types of DDL owned by FUSION. Additionally, some specific priveleges on other schemas is also granted to FUSION. EXECUTE ON various EDN_PUBLISH_EVENT It has the following roles: CTXAPP for managing Oracle Text Objects AQ_SER_ROLE and AQ_ADMINISTRATOR_ROLE for managing Advanced Queues (AQ) FUSION_RUNTIME It has the following privileges: CREATE SESSION CHANGE NOTIFICATION EXECUTE ON various EDN_PUBLISH_EVENT It has the following roles: FUSION_APPS_READ_WRITE for performing DML (Select, Insert, Delete) on Fusion Apps tables FUSION_APPS_EXECUTE for performing execute on objects such as procedures, functions, packages etc. AQ_SER_ROLE and AQ_ADMINISTRATOR_ROLE for managing Advanced Queues (AQ) FUSION_DYNAMIC It has following privileges: CREATE SESSION, PROCEDURE, TABLE, SEQUENCE, SYNONYM, VIEW UNLIMITED TABLESPACE ANALYZE ANY CREATE MINING MODEL EXECUTE on specific procedure, function or package and SELECT on specific tables. This depends on the objects identified by product teams that ADM_DDL needs to have access  in order to perform dynamic DDL statements. There is one more role FUSION_APPS_READ_ONLY which is not attached to any user and has only SELECT privilege on all the Fusion objects. FUSION_RUNTIME does not have any synonyms defined to access objects owned by FUSION schema. A logon trigger is defined in FUSION_RUNTIME which sets the current schema to FUSION and eliminates the need of any synonyms.   What it means for developers? Fusion Application developers should be using FUSION_RUNTIME for testing and running Fusion Applications UI, BC and to connect to any SQL front end like SQL *PLUS, SQL Loader etc. For testing ADFbc using AM tester while using FUSION_RUNTIME you may hit the following error: oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.sql.SQLException, msg=invalid name pattern: FUSION.FND_TABLE_OF_VARCHAR2_255 The fix is to add the below JVM parameter in the Run/Debug client property in the Model project properties -Doracle.jdbc.createDescriptorUseCurrentSchemaForSchemaName=true More details are discussed in this forum thread for it.

  • Collation errors in business

    - by Rob Farley
    At the PASS Summit last month, I did a set (Lightning Talk) about collation, and in particular, the difference between the “English” spoken by people from the US, Australia and the UK. One of the examples I gave was that in the US drivers might stop for gas, whereas in Australia, they just open the window a little. This is what’s known as a paraprosdokian, where you suddenly realise you misunderstood the first part of the sentence, based on what was said in the second. My current favourite is Emo Phillip’s line “I like to play chess with old men in the park, but it can be hard to find thirty-two of them.” Essentially, this a collation error, one that good comedians can get mileage from. Unfortunately, collation is at its worst when we have a computer comparing two things in different collations. They might look the same, and sound the same, but if one of the things is in SQL English, and the other one is in Windows English, the poor database server (with no sense of humour) will get suspicious of developers (who all have senses of humour, obviously), and declare a collation error, worried that it might not realise some nuance of the language. One example is the common scenario of a case-sensitive collation and a case-insensitive one. One may think that “Rob” and “rob” are the same, but the other might not. Clearly one of them is my name, and the other is a verb which means to steal (people called “Nick” have the same problem, of course), but I have no idea whether “Rob” and “rob” should be considered the same or not – it depends on the collation. I told a lie before – collation isn’t at its worst in the computer world, because the computer has the sense to complain about the collation issue. People don’t. People will say something, with their own understanding of what they mean. Other people will listen, and apply their own collation to it. I remember when someone was asking me about a situation which had annoyed me. They asked if I was ‘pissed’, and I said yes. I meant that I was annoyed, but they were asking if I’d been drinking. It took a moment for us to realise the misunderstanding. In business, the problem is escalated. A business user may explain something in a particular way, using terminology that they understand, but using words that mean something else to a technical person. I remember a situation with a checkbox on a form (back in VB6 days from memory). It was used to indicate that something was approved, and indicated whether a particular database field should store True or False – nothing more. However, the client understood it to mean that an entire workflow system would be implemented, with different users have permission to approve items and more. The project manager I’d just taken over from clearly hadn’t appreciated that, and I faced a situation of explaining the misunderstanding to the client. Lots of fun... Collation errors aren’t just a database setting that you can ignore. You need to remember that Americans speak a different type of English to Aussies and Poms, and techies speak a different language to their clients.

  • Backup and Transfer Foobar2000 to a New Computer

    - by Mysticgeek
    If you are a fan of Foobar2000 you undoubtedly have tweaked it to the point where you don’t want to set it all up again on a new machine. Here we look at how to transfer Foobar2000 settings to a new Windows 7 machine. Note: For this article we are transferring Foobar2000 settings from on Windows 7 machine to another over a network running Windows Home Server.  Foobar2000 Foobar2000 is an awesome music player which is highly customizable and we’ve previously covered. Here we take a look at how it’s set up on the current machine. It’s a nothing flashy, but is set up for our needs and includes a lot of components and playlists.   Backup Files Rather than wasting time setting everything up again on a new machine, we can backup the important files and replace them on the new machine. First type or copy the following into the Explorer address bar. %appdata%\foobar2000 Now copy all of the files in the folder and store them on a network drive or some type removable media or device. New Machine Now you can install the latest version of Foobar2000 on your new machine. You can go with a Standard install as we will be replacing our backed up configuration files anyway. When it launches, it will be set with all the defaults…and we want what we had back. Browse to the following on the new machine… %appdata%\foobar2000 Delete all of the files in this directory… Then replace them with the ones we backed up from the other machine. You’ll also want to navigate to C:\Program Files\Foobar2000 and replace the existing Components folder with the backed up one. When you get the screen telling you there is already files of the same name, select Move and Replace, and check the box Do this for the next 6 conflicts. Now we’re back in business! Everything is exactly as it was on the old machine. In this example, we were moving the Foobar2000 files from a computer on the same home network. All the music is coming from a directory on our Windows Home Server so they hadn’t changed. If you’re moving these files to a computer on another machine… say your work computer, you’ll need to adjust where the music folders point to. Windows XP If you’re setting up Foobar2000 on an XP machine, you can enter the following into the Run line. %appdata%\foobar2000 Then copy your backed up files into the Foobar2000 folder, and remember to swap out the Components folder in C:\Program Files\Foobar2000. Confirm to replace the files and folders by clicking Yes to All… Conclusion This method worked perfectly for us on our home network setup. There might be some other things that will need a bit of tweaking, but overall the process is quick and easy. There is a lot of cool things you can do with Foobar2000 like rip an audio CD to FlAC. If you’re a fan of Foobar2000 or considering switching to it, we will be covering more awesome features in future articles.

  • Oracle’s New Memory-Optimized x86 Servers: Getting the Most Out of Oracle Database In-Memory

    - by Josh Rosen, x86 Product Manager-Oracle
    With the launch of Oracle Database In-Memory, it is now possible to perform real-time analytics operations on your business data as it exists at that moment – in the DRAM of the server – and immediately return completely current and consistent data. The Oracle Database In-Memory option dramatically accelerates the performance of analytics queries by storing data in a highly optimized columnar in-memory format.  This is a truly exciting advance in database technology.As Larry Ellison mentioned in his recent webcast about Oracle Database In-Memory, queries run 100 times faster simply by throwing a switch.  But in order to get the most from the Oracle Database In-Memory option, the underlying server must also be memory-optimized. This week Oracle announced new 4-socket and 8-socket x86 servers, the Sun Server X4-4 and Sun Server X4-8, both of which have been designed specifically for Oracle Database In-Memory.  These new servers use the fastest Intel® Xeon® E7 v2 processors and each subsystem has been designed to be the best for Oracle Database, from the memory, I/O and flash technologies right down to the system firmware.Amongst these subsystems, one of the most important aspects we have optimized with the Sun Server X4-4 and Sun Server X4-8 are their memory subsystems.  The new In-Memory option makes it possible to select which parts of the database should be memory optimized.  You can choose to put a single column or table in memory or, if you can, put the whole database in memory.  The more, the better.  With 3 TB and 6 TB total memory capacity on the Sun Server X4-4 and Sun Server X4-8, respectively, you can memory-optimize more, if not your entire database.   Sun Server X4-8 CMOD with 24 DIMM slots per socket (up to 192 DIMM slots per server) But memory capacity is not the only important factor in selecting the best server platform for Oracle Database In-Memory.  As you put more of your database in memory, a critical performance metric known as memory bandwidth comes into play.  The total memory bandwidth for the server will dictate the rate in which data can be stored and retrieved from memory.  In order to achieve real-time analysis of your data using Oracle Database In-Memory, even under heavy load, the server must be able to handle extreme memory workloads.  With that in mind, the Sun Server X4-8 was designed with the maximum possible memory bandwidth, providing over a terabyte per second of total memory bandwidth.  Likewise, the Sun Server X4-4 also provides extreme memory bandwidth in an even more compact form factor with over half a terabyte per second, providing customers with scalability and choice depending on the size of the database.Beyond the memory subsystem, Oracle’s Sun Server X4-4 and Sun Server X4-8 systems provide other key technologies that enable Oracle Database to run at its best.  The Sun Server X4-4 allows for up 4.8 TB of internal, write-optimized PCIe flash while the Sun Server X4-8 allows for up to 6.4 TB of PCIe flash.  This enables dramatic acceleration of data inserts and updates to Oracle Database.  And with the new elastic computing capability of Oracle’s new x86 servers, server performance can be adapted to your specific Oracle Database workload to ensure that every last bit of processing power is utilized.Because Oracle designs and tests its x86 servers specifically for Oracle workloads, we provide the highest possible performance and reliability when running Oracle Database.  To learn more about Sun Server X4-4 and Sun Server X4-8, you can find more details including data sheets and white papers here. Josh Rosen is a Principal Product Manager for Oracle’s x86 servers, focusing on Oracle’s operating systems and software.  He previously spent more than a decade as a developer and architect of system management software. Josh has worked on system management for many of Oracle's hardware products ranging from the earliest blade systems to the latest Oracle x86 servers.

  • How to reproject a shapefile from WGS 84 to Spherical/Web Mercator projection.

    - by samkea
    Definitions: You will need to know the meaning of these terms below. I have given a small description to the acronyms but you can google and know more about them. #1:WGS-84- World Geodetic Systems (1984)- is a standard reference coordinate system used for Cartography, Geodesy and Navigation. #2: EPGS-European Petroleum Survey Group-was a scientific organization with ties to the European petroleum industry consisting of specialists working in applied geodesy, surveying, and cartography related to oil exploration. EPSG::4326 is a common coordinate reference system that refers to WGS84 as (latitude, longitude) pair coordinates in degrees with Greenwich as the central meridian. Any degree representation (e.g., decimal or DMSH: degrees minutes seconds hemisphere) may be used. Which degree representation is used must be declared for the user by the supplier of data. So, the Spherical/Web Mercator projection is referred to as EPGS::3785 which is renamed to EPSG:900913 by google for use in googlemaps. The associated CRS(Coordinate Reference System) for this is the "Popular Visualisation CRS / Mercator ". This is the kind of projection that is used by GoogleMaps, BingMaps,OSM,Virtual Earth, Deep Earth excetra...to show interactive maps over the web with thier nearly precise coordinates.  Reprojection: After reading alot about reprojecting my coordinates from the deepearth project on Codeplex, i still could not do it. After some help from a colleague, i got my ball rolling.This is how i did it. #1 You need to download and open your shapefile using Q-GIS; its the one with the biggest number of coordinate reference systems/ projections. #2 Use the plugins menu, and enable ftools and the WFS plugin. #3 Use the Vector menu--> Data Management Tools and choose define current projection. Enable, use predefined reference system and choose WGS 84 coodinate system. I am personally in zone 36, so i chose WGS84-UTM Zone 36N under ( Projected Coordinate Systems--> Universal Transverse Mercator) and click ok. #4 Now use the Vector menu--> Data Management Tools and choose export to new projection. The same dialog will pop-up. Now choose WGS 84 EPGS::4326 under Geodetic Coordinate Systems. My Input user Defined Spatial Reference System should looks like this: +proj=tmerc +lat_0=0 +lon_0=33 +k=0.9996 +x_0=500000 +y_0=200000 +ellps=WGS84 +datum=WGS84 +units=m +no_defs Your Output user Defined Spatial Reference System should look like this: +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs Browse for the place where the shapefile is going to be and give the shapefile a name(like origna_reprojected). If it prompts you to add the projected layer to the TOC, accept. There, you have your re-projected map with latitude and longitude pair of coordinates. #5 Now, this is not the actual Spherical/Web Mercator projection, but dont worry, this is where you have to stop. All the other custom web-mapping portals will pick this projection and transform it into EPGS::3785 or EPSG:900913 but the coordinates will still remain as the LatLon pair of the projected shapefile. If you want to test, a particular know point, Q-GIS has a lot of room for that. Go ahead and test it.

  • Windows Azure Use Case: Agility

    - by BuckWoody
    This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx  Description: Agility in this context is defined as the ability to quickly develop and deploy an application. In theory, the speed at which your organization can develop and deploy an application on available hardware is identical to what you could deploy in a distributed environment. But in practice, this is not always the case. Having an option to use a distributed environment can be much faster for the deployment and even the development process. Implementation: When an organization designs code, they are essentially becoming a Software-as-a-Service (SaaS) provider to their own organization. To do that, the IT operations team becomes the Infrastructure-as-a-Service (IaaS) to the development teams. From there, the software is developed and deployed using an Application Lifecycle Management (ALM) process. A simplified view of an ALM process is as follows: Requirements Analysis Design and Development Implementation Testing Deployment to Production Maintenance In an on-premise environment, this often equates to the following process map: Requirements Business requirements formed by Business Analysts, Developers and Data Professionals. Analysis Feasibility studies, including physical plant, security, manpower and other resources. Request is placed on the work task list if approved. Design and Development Code written according to organization’s chosen methodology, either on-premise or to multiple development teams on and off premise. Implementation Code checked into main branch. Code forked as needed. Testing Code deployed to on-premise Testing servers. If no server capacity available, more resources procured through standard budgeting and ordering processes. Manual and automated functional, load, security, etc. performed. Deployment to Production Server team involved to select platform and environments with available capacity. If no server capacity available, standard budgeting and procurement process followed. If no server capacity available, systems built, configured and put under standard organizational IT control. Systems configured for proper operating systems, patches, security and virus scans. System maintenance, HA/DR, backups and recovery plans configured and put into place. Maintenance Code changes evaluated and altered according to need. In a distributed computing environment like Windows Azure, the process maps a bit differently: Requirements Business requirements formed by Business Analysts, Developers and Data Professionals. Analysis Feasibility studies, including budget, security, manpower and other resources. Request is placed on the work task list if approved. Design and Development Code written according to organization’s chosen methodology, either on-premise or to multiple development teams on and off premise. Implementation Code checked into main branch. Code forked as needed. Testing Code deployed to Azure. Manual and automated functional, load, security, etc. performed. Deployment to Production Code deployed to Azure. Point in time backup and recovery plans configured and put into place.(HA/DR and automated backups already present in Azure fabric) Maintenance Code changes evaluated and altered according to need. This means that several steps can be removed or expedited. It also means that the business function requesting the application can be held directly responsible for the funding of that request, speeding the process further since the IT budgeting process may not be involved in the Azure scenario. An additional benefit is the “Azure Marketplace”, In effect this becomes an app store for Enterprises to select pre-defined code and data applications to mesh or bolt-in to their current code, possibly saving development time.

  • Extracting the Date from a DateTime in Entity Framework 4 and LINQ

    - by Ken Cox [MVP]
    In my current ASP.NET 4 project, I’m displaying dates in a GridDateTimeColumn of Telerik’s ASP.NET Radgrid control. I don’t care about the time stuff, so my DataFormatString shows only the date bits: <telerik:GridDateTimeColumn FilterControlWidth="100px"   DataField="DateCreated" HeaderText="Created"    SortExpression="DateCreated" ReadOnly="True"    UniqueName="DateCreated" PickerType="DatePicker"    DataFormatString="{0:dd MMM yy}"> My problem was that I couldn’t get the built-in column filtering (it uses Telerik’s DatePicker control) to behave.  The DatePicker assumes that the time is 00:00:00 but the data would have times like 09:22:21. So, when you select a date and apply the EqualTo filter, you get no results. You would get results if all the time portions were 00:00:00. In essence, I wanted my Entity Framework query to give the DatePicker what it wanted… a Date without the Time portion. Fortunately, EF4 provides the TruncateTime  function. After you include Imports System.Data.Objects.EntityFunctions You’ll find that your EF queries will accept the TruncateTime function. Here’s my routine: Protected Sub RadGrid1_NeedDataSource _     (ByVal source As Object, _      ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) _     Handles RadGrid1.NeedDataSource     Dim ent As New OfficeBookDBEntities1     Dim TopBOMs = From t In ent.TopBom, i In ent.Items _                   Where t.BusActivityID = busActivityID _       And i.BusActivityID And t.ItemID = i.RecordID _       Order By t.DateUpdated Descending _       Select New With {.TopBomID = t.TopBomID, .ItemID = t.ItemID, _                        .PartNumber = i.PartNumber, _                        .Description = i.Description, .Notes = t.Notes, _                        .DateCreated = TruncateTime(t.DateCreated), _                        .DateUpdated = TruncateTime(t.DateUpdated)}     RadGrid1.DataSource = TopBOMs End Sub Now when I select March 14, 2011 on the DatePicker, the filter doesn’t stumble on time values that don’t make sense. Full Disclosure: Telerik gives me (and other developer MVPs) free copies of their suite.

  • Creating an HttpHandler to handle request of your own extension

    - by Jalpesh P. Vadgama
    I have already posted about http handler in details before some time here. Now let’s create an http handler which will handle my custom extension. For that we need to create a http handlers class which will implement Ihttphandler. As we are implementing IHttpHandler we need to implement one method called process request and another one is isReusable property. The process request function will handle all the request of my custom extension. so Here is the code for my http handler class. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; namespace Experiement { public class MyExtensionHandler:IHttpHandler { public MyExtensionHandler() { //Implement intialization here } bool IHttpHandler.IsReusable { get { return true; } } void IHttpHandler.ProcessRequest(HttpContext context) { string excuttablepath = context.Request.AppRelativeCurrentExecutionFilePath; if (excuttablepath.Contains("HelloWorld.dotnetjalps")) { Page page = new HelloWorld(); page.AppRelativeVirtualPath = context.Request.AppRelativeCurrentExecutionFilePath; page.ProcessRequest(context); } } } } Here in above code you can see that in process request function I am getting current executable path and then I am processing that page. Now Lets create a page with extension .dotnetjalps and then we will process this page with above created http handler. so let’s create it. It will create a page like following. Now let’s write some thing in page load Event like following. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace Experiement { public partial class HelloWorld : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Response.Write("Hello World"); } } } Now we have to tell our web server that we want to process request from this .dotnetjalps extension through our custom http handler for that we need to add a tag in httphandler sections of web.config like following. <configuration> <system.web> <compilation debug="true" targetFramework="4.0" /> <httpHandlers> <add verb="*" path="*.dotnetjalps" type="Experiement.MyExtensionHandler,Experiement"/> </httpHandlers> </system.web> </configuration> That’s it now run that page into browser and it will execute like following in browser That’s you.. Isn’t it cool.. Stay tuned for more.. Happy programming.. Technorati Tags: HttpHandler,ASP.NET,Extension

  • How do I fix my resolution after Directx install through Steam?

    - by Justin
    I'm a bit long-winded so see bottom for quick version and specs. Friendly Hello: Hello all on these askUbuntu pages, I just recently built my own computer and decided to switch to Ubuntu for the extra coolness. I've been learning a lot through all this, and mostly been trying to figure out issues on my own (read: Google searches). However, I couldn't seem to find others with this problem so I've come here for help. Detailed Recount: So I just used WINE and WINETRICKS to install Steam. All went well and it worked. Then I went to trying a game out. I remembered that Orcs Must Die! worked from http://www.steamgamesonlinux.com/ so I tried that out. After selecting to download it, that's when the problem occurred. The screen suddenly zoomed in!!! I think it's the resolution right? Half the screen is cut off and I can't see parts of the right side of windows. My theory is that this is due to Direct X being installed through Steam, as Steam automatically installed it as I chose to download the game. It didn't even ask me to install Direct X or not ): It all happened so fast. This all being said, the game works fine! It looks a little strange, as if the resolution was off, but it plays just fine. What I did so far: Restarted my computer. Didn't work -_- Researched Steam installing DirectX on Ubuntu then messing up resolution and couldn't really find anything. Researched uninstalling DirectX from Ubuntu but only found uninstalling DirectX after having been installed with Wine, not through Steam. Got mad and ate my feelings. Tried "xrandr -s 0" but it didn't do anything. Ran xrandr alone and terminal showed this: Screen 0: minimum 8 x 8, current 640 x 480, maximum 16384 x 16384 DVI-I-0 connected 640x480+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 640x480 59.9*+ 320x240 120.1 DVI-I-1 disconnected (normal left inverted right x axis y axis) HDMI-0 disconnected (normal left inverted right x axis y axis) DP-0 disconnected (normal left inverted right x axis y axis) DVI-D-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) About now I was mad so I played Odin's Sphere then took a nap. Back to it! I entered the following: xrandr --output DVI-I-0 --mode 1024x768 But I was met with this message: xrandr: cannot find mode 1024x768 I get the same messages for 800x600, 1400x1050, and seemingly any other combination of numbers. I then tried Going into System Settings then Displays, then playing around in there. My Resolution is set to 640x480 and there are no other options for me to choose from. Rotation has Normal, Clockwise, Counter Clockwise, and 180 Degrees. It's set to Normal and I haven't messed with that. Launcher Placement has Unknown and All Displays as its two options. It's set to Unknown, but moving it to All Displays doesn't seem to do anything. Finally, when I click Detect Displays, nothing seems to happen. Quick Version: Linux noob. Steam installed with Wine and Winetricks. Steam downloaded and installed game + DirectX. Resolution messed up now (I think; pretty sure), can't fix it, very annoying, no idea what's going on, halp! Specs: Ubuntu Version 12.04 Wine Version 1.4.1 Have not changed any settings in Wine Using Winetricks Graphics Card: http://www.gigabyte.com/products/pro...px?pid=4361#sp Drivers: Proprietary (Installing those were a LOT of fun) Also let it be known that I have a DVI to VGA cord running from my Graphics card to my monitor. If any more information is needed I am ready to report. Thank You: Thanks a lot for your help and all the work you do to support noob ubuntuers like me (:

  • July, the 31 Days of SQL Server DMO’s – Day 22 (sys.dm_db_index_physical_stats)

    - by Tamarick Hill
    The sys.dm_db_index_physical_stats Dynamic Management Function is used to return information about the fragmentation levels, page counts, depth, number of levels, record counts, etc. about the indexes on your database instance. One row is returned for each level in a given index, which we will discuss more later. The function takes a total of 5 input parameters which are (1) database_id, (2) object_id, (3) index_id, (4) partition_number, and (5) the mode of the scan level that you would like to run. Let’s use this function with our AdventureWorks2012 database to better illustrate the information it provides. SELECT * FROM sys.dm_db_index_physical_stats(db_id('AdventureWorks2012'), NULL, NULL, NULL, NULL) As you can see from the result set, there is a lot of beneficial information returned from this DMF. The first couple of columns in the result set (database_id, object_id, index_id, partition_number, index_type_desc, alloc_unit_type_desc) are either self-explanatory or have been explained in our previous blog sessions so I will not go into detail about these at this time. The next column in the result set is the index_depth which represents how deep the index goes. For example, If we have a large index that contains 1 root page, 3 intermediate levels, and 1 leaf level, our index depth would be 5. The next column is the index_level which refers to what level (of the depth) a particular row is referring to. Next is probably one of the most beneficial columns in this result set, which is the avg_fragmentation_in_percent. This column shows you how fragmented a particular level of an index may be. Many people use this column within their index maintenance jobs to dynamically determine whether they should do REORG’s or full REBUILD’s of a given index. The fragment count represents the number of fragments in a leaf level while the avg_fragment_size_in_pages represents the number of pages in a fragment. The page_count column tells you how many pages are in a particular index level. From my result set above, you see the the remaining columns all have NULL values. This is because I did not specify a ‘mode’ in my query and as a result it used the ‘LIMITED’ mode by default. The LIMITED mode is meant to be lightweight so it does collect information for every column in the result set. I will re-run my query again using the ‘DETAILED’ mode and you will see we now have results for these rows. SELECT * FROM sys.dm_db_index_physical_stats(db_id('AdventureWorks2012'), NULL, NULL, NULL, ‘DETAILED’)   From the remaining columns, you see we get even more detailed information such as how many records are in a particular index level (record_count). We have a column for ghost_record_count which represents the number of records that have been marked for deletion, but have not physically been removed by the background ghost cleanup process. We later see information on the MIN, MAX, and AVG record size in bytes. The forwarded_record_count column refers to records that have been updated and now no longer fit within the row on the page anymore and thus have to be moved. A forwarded record is left in the original location with a pointer to the new location. The last column in the result set is the compressed_page_count column which tells you how many pages in your index have been compressed. This is a very powerful DMF that returns good information about the current indexes in your system. However, based on the mode you select, it could be a very resource intensive function so be careful with how you use it. For more information on this Dynamic Management Function, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms188917.aspx Follow me on Twitter @PrimeTimeDBA
