• Silverlight Cream for April 29, 2010 -- #851

  - by Dave Campbell

  In this Issue: Carlos Figueira(-2-), Subodh Pushpak, Gergely Orosz, John Papa, Mike Snow(-2-), Rishi, Tim Heuer, Stefan Olson, and David Anson. Shoutouts: Josh Holmes blogged about a cool app the City of Miami has up: Miami 311: Built on Windows Azure Gergely Orosz reports on the state of a bug he found pre SL4: Silverlight 4 still displays large elements incorrectly Laura Foy and Charlie Kindel discuss WP7 on Channel 9: Windows Phone 7 Developer Tools Refresh Announced Charlie Kindel has an announcement, good instructions, and what's new notes on the Windows Phone Developer Tools CTP Refresh! Tim Heuer mentioned the workaround for this in his post (below), but I thought you might like to read Brandon Watson's debrief of what it's all about: Signed Assemblies Bug in the Windows Phone Tools CTP Refresh Laurent Bugnion posted about interrelations between versions of Blend and WP7 code... read it closely: Be careful when installing the Blend Windows Phone 7 Add-In From SilverlightCream.com: Consuming REST/POX services in Silverlight 4 Carlos Figueira has a pair of posts up about consuming services in Silverlight 4. This first one is about consuming REST/POX services. He provides a Service Contract that can be used with either and the full project code is available as well. Consuming REST/JSON services in Silverlight 4 In the second post, Carlos Figueira provides the code to allow WCF and Silverlight 4 to consume strongly-typed REST/JSON... and again, all the code is available. Silverlight and WCF caching Subodh Pushpak has a post up discussing caching in WCF, and has code demonstrating turning caching on at run-time. Detecting Silverlight Version Installed Gergely Orosz said it right when he said "Detecting the Silverlight version installed on a client machine isn’t entirely straightforward." ... and after reading this post, if you take the link to his ScottLogic blog, you'll get a full break-out of how it's done. Silverlight TV 22: Tim Heuer on Extending the SMF It's Thursday, and that means Silverlight TV! ... this week, John Papa has on Tim Heuer who has always been out there pushing media... and he's talking about SMF or Silverlight Media Framework for the uninitiated, and also extending it. Silverlight Tip of the Day #7 – Localized Resources Mike Snow has Tip Number 7 up and it's about localization... good end-to-end discussion and demonstration. Just thought I should use that to prove to my daughter that the tatoo she had put on the back of her neck actually reads "Eat More Broccoli" :) Silverlight Tip of the Day #8 – Detecting Alt, Shift, Control, Window & Apple Keys Combinations I just realized Mike Snow's site logo reads "Silverlight Tips of the Day" (bolding mine) ... that answers why I'm seeing more than one -- sorry Mike, couldn't pass it up :) ... Mike's second tip today and number 8 in the series is on detecting all the mouse button and ctl/alt/shift combinations in Silverlight. nRoute: More Wholesomeness, with SL 4 and .NET 4.0 Rishi has a post up announcing a new nRoute release for Silverlight 4 and .NET 4.0 He's tweaked the code to take advantages of enhancements in the new platforms, so check it out. Windows Phone 7 Developer Tools April 2010 Refresh Booya... Tim Heuer announced the release of the next drop in the WP7 tools ... dang wish I was at home today :) ... be sure to read the post for info such as the notes about Authenticode Assemblies and the release notes. Updates to Silverlight Multi-binding support Stefan Olson points up a SL4 change to Multi-binding support that he had previously blogged about. He shows the previous non-working example, and what you have to do to make it work now. Using XAML to create a custom wallpaper image for your mobile device David Anson has a solution for those pesky lost devices, and let me go on the record right now saying if anyone finds a WP7 phone laying around, just call me, it's mine :) [think that'd work??] ... ok, David's solution is a WPF app "MobileDeviceHomeScreenMaker" that you get the info set and it produces a png you then put on your device. But seriously about that lost phone... Stay in the 'Light!

• Keeping up with Technology

  - by kennedysteve

  If you're like me, you have a hard time keeping up with all the technologies out there. The reality is there's too many new technologies (languages, methodologies,  tools, etc). One of the ways I try to keep up with everything is by using good ol' RSS feeds in conjunction with Google Reader. Google Reader is both an online aggregator of RSS feeds, and it also has a good companion app on Google Android. The nicest part of Google Reader for me is the "All Listings" view which gives me a reverse chronological view of ALL articles (mixed together) regardless of the actual RSS feed.  This way, I get to see the newest articles first. I can then choose to hide the articles I've viewed, etc. Here is a list of my RSS feeds. Admittedly, some of these are all over the spectrum. But you might find one or two interesting. .NET Rocks!

• My new laptop - with a really nice battery option

  - by Rob Farley

  It was about time I got a new laptop, and so I made a phone-call to Dell to discuss my options. I decided not to get an SSD from them, because I’d rather choose one myself – the sales guy tells me that changing the HD doesn’t void my warranty, so that’s good (incidentally, I’d love to hear people’s recommendations for which SSD to get for my laptop). Unfortunately this machine only has one HD slot, but I figure that I’ll put lots of stuff onto external disks anyway. The machine I got was a Dell Studio XPS 16. It’s red (which suits my company), but also has the Intel® Core™ i7-820QM Processor, which is 4 Cores/8 Threads. Makes for a pretty Task Manager, but nothing like the one I saw at SQLBits last year (at 96 cores), or the one that my good friend James Rowland-Jones writes about here. But the reason for this post is actually something in the software that comes with the machine – you know, the stuff that most people uninstall at the earliest opportunity. I had just reinstalled the operating system, and was going through the utilities to get the drivers up-to-date, when I noticed that one of Dell applications included an option to disable battery charging. So I installed it. And sure enough, I can tell the battery not to charge now. Clearly Dell see it as a temporary option, and one that’s designed for when you’re on a plane. But for me, I most often use my laptop with the power plugged in, which means I don’t need to have my battery continually topping itself up. So I really love this option, but I feel like it could go a little further. I’d like “Not Charging” to be the default option, and let me set it when I want to charge it (which should theoretically make my battery last longer). I also intend to work out how this option works, so that I can script it and put it into my StartUp options (so it can be the Default setting). Actually – if someone has already worked this out and can tell me what it does, then please feel free to let me know. Even better would be an external switch. I had a switch on my old laptop (a Dell Latitude) for WiFi, so that I could turn that off before I turned on the computer (this laptop doesn’t give me that option – no physical switch for flight mode). I guess it just means I’ll get used to leaving the WiFi off by default, and turning it on when I want it – might save myself some battery power that way too. Soon I’ll need to take the plunge and sync my iPhone with the new laptop. I’m a little worried that I might lose something – Apple’s messages about how my stuff will be wiped and replaced with what’s on the PC doesn’t fill me with confidence, as it’s a new PC that doesn’t have stuff on it. But having a new machine is definitely a nice experience, and one that I can recommend. I’m sure when I get around to buying an SSD I’ll feel like it’s shiny and new all over again!

• 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.

• Expression Studio 4 - without SketchFlow&hellip;

  - by mbcrump

  is kinda like an explosion with no “Ka-Boom”… I was excited to hear the news yesterday at Microsoft Teched that Expression Studio 4 had officially launched. MSDN subscribers could log in and download the full release. So, I logged into my MSDN account and started downloading Expression Studio 4 Premium thinking that I was only minutes away from trying out SketchFlow 4. To my dismay, I launched Blend 4 and noticed it did not say SketchFlow on the splash screen. So, I went to New Project and the template was not available. After some digging around on the net, I learned my premium MSDN subscription did not include SketchFlow and I would need to purchase the Ultimate Edition. Below is a excerpt directly from Microsoft: Q: What products are included in the Microsoft Expression Studio 4 Ultimate? A: Expression Studio 4 Ultimate is comprised of 4 products, Expression Web 4, Microsoft Expression Blend® 4 + SketchFlow, Expression Encoder 4 Pro and Expression Design 4. Expression Blend 4 includes SketchFlow in Expression Studio 4 Ultimate product only. Q: What products are included in the Microsoft Expression Studio 4 Premium? A: Expression Studio 4 Premium is comprised of 4 products, Expression Web 4, Microsoft Expression Blend 4, Expression Encoder 4 and Expression Design 4. Expression Studio 4 Premium is not available for retail purchase. Q: What products are included in the Microsoft Expression Studio 4 Web Professional? A: Expression Studio 4 Web Professional is comprised of 3 products, Expression Web 4, Expression Encoder 4 and Expression Design 4. As you can see, we got screwed on this deal and plenty of people are complaining: Kiran Says: 6.07.2010 at 5:07 PM No SketchFlow for Expression Studio 4 Premium? What a bumper for Microsoft Partners!! Martin Says: 6.07.2010 at 6:18 PM Why does Expression Professional Subscription not include upgrades and new releases of Expression Studio. Good question hey. I bought my subscription 5 days ago thinking I would get what i purchased but no Expression upgrades or new releases for me, what a waste of money. I think I am not the only long term user of this software that feels disgruntled. Sorry john just had to tell someone. shaggygi Says: 6.07.2010 at 7:31 PM SketchFlow NOT included in Studio 4? WTF! I repeat.... WT...Freaking.... F! This is totally unacceptable. My development team purchased VS 2010 Premium w/ MSDN with the impression by Adam Kinney, Scott Guthrie, etc. that this would be included in the Premium package or some sort of free upgrade. I understand this is a Marketing thing, but come on! I believe, at very least, this should have been explained in detail before this release. John Papa... as a rep to give feedback to the team... Please please and please.... tell powers-at-be to fix this problem. Sorry for the rant. Besides this issue, I believe it is a very good product:) Thanks Vaclav Elias Says: 6.08.2010 at 4:30 AM Well, I am also not happy that SketchFlow is only for the chosen ones :-) It is very nice product. Actually, kind of foundation for web development so they could really support any MSDN subscribers.. :-( I am hoping that Microsoft will make this right for all of us with MSDN premier subscriptions. In the meantime,  you can check out the 5 day training series available here.

• Book Reviews: Art of Community and Eyetracking Web Usability

  - by ultan o'broin

  Holidays time offers a chance to catch up on some user experience and user assistance related material. So, two short book reviews (which I considered using my new Tumblr blog for. More about that another time) coming up. The Art of Community by Jono Bacon Excellent starting point for anyone wanting to get going in the community software (FLOSS, for example) space or understand how to set up, manage, and leverage the collective intelligence of communities for whatever ends. The book is a little too long in my opinion, and of course, usage of what Jono is recommending needs to be nuanced and adapted for enterprise applications space (hardly surprising there is a lot about Ubuntu, Lug Radio, and so on given Jono's interests). Shame there wasn't more information on international, non-English community considerations too. Still, some great ideas and insight into setting up and managing communities that I will leverage (watch out for the results on this blog, later in 2011). One section, on collaborative writing really jumped out. It reinforced the whole idea that to successful community initiatives are based on instigators knowing what makes the community tick in the first place. How about this for insight into user profiles for people who write community user assistance (OK then, "doc") and what tools they might use (in this case, we're talking about Jokosher): "Most people who write documentation for open source software projects would fall into the category of power user. They are technology enthusiasts who are not interested in the super-technical avenues of programming, but want to help out. Many of these people have good writing skills and a good knowledge of using the software, so the documentation fit is natural. With Jokosher we wanted to acknowledge this profile of user. As such, instead of focussing on complex text processing tools, we encouraged our documentation contributors to use a wiki." The book is available for free here, and well as being available from usual sources. Eyetracking Web Usability by Jakob Nielsen and Kara Prentice Another fine book by established experts. I have some field experience of eyetracking studies myself --in the user assistance for enterprise applications space--though Jakob and Kara concentrate on websites for their research here. I would caution how much about websites transfers easily to the applications space, especially enterprise applications, as claimed in the book too. However, Jakob and Kara do make the case very well that understanding design goals (for example, productivity improvement in the case of applications) and the context of the software use is critical. Executing a study using eyetracking technology requires that you know what you want to test, can set up realistic tasks for testing by representative testers, and then analyze the results. Be precise, as lots of data will be generated (I think the authors underplay the effort in analyzing data too). What I found disappointing was the lack of emphasis on eyetracking as only part of the usability solution. It's really for fine-tuning designs in my opinion, and should be used after other design reviews. I also wasn't that crazy about the level of disengagement between the qualitative and quantitative side of this kind of testing that the book indicated. I think it is useful to have testers verbalize their thoughts and for test engineers to prompt, intervene, or guide as necessary. More on cultural or international aspects to usability testing might have been included too (websites are available to everyone). To conclude, I enjoyed the book, took on board some key takeaways about methodologies and found the recommendations sensible and easy to follow (for example about Forms layouts). Applying enterprise applications requirements such as those relating to user profiles, design goals, and overall context of use in conjunction with what's in this book would be the way to go here. It also made me think of how interesting it would be to compare eyetracking findings between website and enterprise applications usage.

• Pie Charts Just Don't Work When Comparing Data - Number 10 of Top 10 Reasons to Never Ever Use a Pie

  - by Tony Wolfram

  When comparing data, which is what a pie chart is for, people have a hard time judging the angles and areas of the multiple pie slices in order to calculate how much bigger one slice is than the others. Pie Charts Don't Work A slice of pie is good for serving up a portion of desert. It's not good for making a judgement about how big the slice is, what percentage of 100 it is, or how it compares to other slices. People have trouble comparing angles and areas to each other. Controlled studies show that people will overestimate the percentage that a pie slice area represents. This is because we have trouble calculating the area based on the space between the two angles that define the slice. This picture shows how a pie chart is useless in determing the largest value when you have to compare pie slices.   You can't compare angles and slice areas to each other. Human perception and cognition is poor when viewing angles and areas and trying to make a mental comparison. Pie charts overload the working memory, forcing the person to make complicated calculations, and at the same time make a decision based on those comparisons. What's the point of showing a pie chart when you want to compare data, except to say, "well, the slices are almost the same, but I'm not really sure which one is bigger, or by how much, or what order they are from largest to smallest. But the colors sure are pretty. Plus, I like round things. Oh,was I suppose to make some important business decision? Sorry." Bad Choices and Bad Decisions Interaction Designers, Graphic Artists, Report Builders, Software Developers, and Executives have all made the decision to use pie charts in their reports, software applications, and dashboards. It was a bad decision. It was a poor choice. There are always better options and choices, yet the designer still made the decision to use a pie chart. I'll expore why people make such poor choices in my upcoming blog entires. (Hint: It has more to do with emotions than with analytical thinking.) I've outlined my opinions and arguments about the evils of using pie charts in "Countdown of Top 10 Reasons to Never Ever Use a Pie Chart." Each of my next 10 blog entries will support these arguments with illustrations, examples, and references to studies. But my goal is not to continuously and endlessly rage against the evils of using pie charts. This blog is not about pie charts. This blog is about understanding why designers choose to use a pie chart. Why, when give better alternatives, and acknowledging the shortcomings of pie charts, do designers over and over again still freely choose to place a pie chart in a report? As an extra treat and parting shot, check out the nice pie chart that Wikipedia uses to illustrate the United States population by state.   Remember, somebody chose to use this pie chart, with all its glorious colors, and post it on Wikipedia for all the world to see. My next blog will give you a better alternative for displaying comparable data - the sorted bar chart.

• SQL SERVER – DMV – sys.dm_os_wait_stats Explanation – Wait Type – Day 3 of 28

  - by pinaldave

  The key Dynamic Management View (DMV) that helps us to understand wait stats is sys.dm_os_wait_stats; this DMV gives us all the information that we need to know regarding wait stats. However, the interpretation is left to us. This is a challenge as understanding wait stats can often be quite tricky. Anyway, we will cover few wait stats in one of the future articles. Today we will go over the basic understanding of the DMV. The Official Book OnLine Reference for DMV is over here: sys.dm_os_wait_stats. I suggest you all to refer this for all the accuracy. Following is a statement from the online book: “Specific types of wait times during query execution can indicate bottlenecks or stall points within the query. Similarly, high wait times, or wait counts server wide can indicate bottlenecks or hot spots in interaction query interactions within the server instance.” This is the statement which has inspired me to write this series. Let us first run the following statement from DMV. SELECT * FROM sys.dm_os_wait_stats ORDER BY wait_time_ms DESC GO Above statement will show us few of the columns. Here it is quick explanation of each of the column. wait_type – this is the name of the wait type. There can be three different kinds of wait types – resource, queue and external. waiting_tasks_count – this incremental counter is a good indication of frequent the wait is happening. If this number is very high, it is good indication for us to investigate that particular wait type. It is quite possible that the wait time is considerably low, but the frequency of the wait is much high. wait_time_ms – this is total wait accumulated for any type of wait. This is the total wait time and includes singal_wait_time_ms. max_wait_time_ms – this indicates the maximum wait type ever occurred for that particular wait type. Using this, one can estimate the intensity of the wait type in past. Again, it is not necessary that this max wait time will occur every time; so do not over invest yourself here. signal_wait_time_ms – this is the wait time when thread is marked as runnable and it gets to the running state. If the runnable queue is very long, you will find that this wait time becomes high. Additionally, please note that this DMV does not show current wait type or wait stats. This is cumulative view of the all the wait stats since server (instance) restarted or wait stats have been cleared. In future blog post, we will also cover two more DMVs which can be helpful to identify wait-related issues. ?sys.dm_os_waiting_tasks sys.dm_exec_requests Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Pinal Dave, PostADay, SQL, SQL Authority, SQL DMV, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, SQL Wait Stats, SQL Wait Types, T SQL, Technology

• How to use caching to increase render performance?

  - by Christian Ivicevic

  First of all I am going to cover the basic design of my 2d tile-based engine written with SDL in C++, then I will point out what I am up to and where I need some hints. Concept of my engine My engine uses the concept of GameScreens which are stored on a stack in the main game class. The main methods of a screen are usually LoadContent, Render, Update and InitMultithreading. (I use the last one because I am using v8 as a JavaScript bridge to the engine. The main game loop then renders the top screen on the stack (if there is one; otherwise, it exits the game) - actually it calls the render methods, but stores all items to be rendered in a list. After gathering all this information the methods like SDL_BlitSurface are called by my GameUIRenderer which draws the enqueued content and then draws some overlay. The code looks like this: while(Game is running) { Handle input if(Screens on stack == 0) exit Update timer etc. Clear the screen Peek the screen on the stack and collect information on what to render Actually render the enqueue screen stuff and some overlay etc. Flip the screen } The GameUIRenderer uses as hinted a std::vector<std::shared_ptr<ImageToRender>> to hold all necessary information described by this class: class ImageToRender { private: SDL_Surface* image; int x, y, w, h, xOffset, yOffset; }; This bunch of attributes is usually needed if I have a texture atlas with all tiles in one SDL_Surface and then the engine should crop one specific area and draw this to the screen. The GameUIRenderer::Render() method then just iterates over all elements and renders them something like this: std::for_each( this->m_vImageVector.begin(), this->m_vImageVector.end(), [this](std::shared_ptr<ImageToRender> pCurrentImage) { SDL_Rect rc = { pCurrentImage->x, pCurrentImage->y, 0, 0 }; // For the sake of simplicity ignore offsets... SDL_Rect srcRect = { 0, 0, pCurrentImage->w, pCurrentImage->h }; SDL_BlitSurface(pCurrentImage->pImage, &srcRect, g_pFramework->GetScreen(), &rc); } ); this->m_vImageVector.clear(); Current ideas which need to be reviewed The specified approach works really good and IMHO it is really has a good structure, however the performance could be definitely increased. I would like to know what do you suggest, how to implement efficient caching of surfaces etc so that there is no need to redraw the same scene over and over again? The map itself would be almost static, only when the player moves, we would need to move the map. Furthermore animated entities would either require updates of the whole map or updates of only the specific areas the entities are currently moving in. My first approaches were to include a flag IsTainted which should be used by the GameUIRenderer to decide whether to redraw everything or use cached version (or to not render anything so that we do not have to Clear the screen and let the last frame persist). However this seems to be quite messy if I have to manually handle in my Render method of the screen class if something has changed or not.

• Dude, what’s up with POP Forums vNext?

  - by Jeff

  Yeah, it has been awhile. I posted v9.2 back in January, about five months ago. That’s a real change from the release pace I had there for awhile. Let me explain what’s going on. First off, in the interim, I re-launched CoasterBuzz, which required a lot of my attention for about two of those months. That’s a good thing though, because that site is just about the best test bed I could ask for. The other thing is that I committed to make the next version use ASP.NET MVC 4, which is now at the RC stage. I didn’t think much about when they’d hit their RTW point, but RC is good enough for me. To that end, there is enough change in the next version that I recently decided to make it a major version upgrade, and finish up the loose ends and science projects to make it whole. Here’s what’s in store… Mobile views: I sat on this or a long time. Originally, I was going to use jQuery Mobile, and waited and waited for a new release, but in the end, decided against using it. Sometimes buttons would unexplainably not work, I felt like I was fighting it at times, and the CSS just felt too heavy. I rolled my own mobile sugar at a fraction of the size, and I think you’ll find it easy to modify. And it’s Metro-y, of course! Re-do of background services: A number of things run in the background, and I did quite a bit of “reimagining” of that code. It’s the weirdness of running services in a Web site context, because so many folks can’t run a bona fide service on their host’s box. The biggest change here is that these service no longer start up by default. You’ll need to call a new method from global.asax called PopForumsActivation.StartServices(). This is also a precursor to running the app in a Web farm (new data layer and caching is the second part of that). I learned about this the hard way when I had three apps using the forum library code but only one was actually the forum. The services were all running three times as often with race conditions and hits on the same data. That was particularly bad for e-mail. CSS clean up: It’s still not ideal, but it’s getting better. That’s one of those things that comes with integrating to a real site… you discover all of the dumb things you did. The mobile CSS is particularly easier to live with. Bug fixes: There are a whole lot of them. Most were minor, but it’s feeling pretty solid now. So that’s where I am. I’m going to call it v10.0, and I’m going to really put forth some effort toward finishing the mobile experience and getting through the remaining bugs. The roadmap beyond that will likely not be feature oriented, but rather work on some other things, like making it run in Azure, perhaps using SQL CE, a better install experience, etc. As usual, I’ll post the latest here. Stay tuned!

• Your Job Search Should be More Than Just a New Year's Resolution

  - by david.talamelli

  I love the beginning of a new year, it is a great chance to refocus and either re-evaluate goals you are working to or even set new ones. I don't have any statistics to measure this but I am sure that one of the more popular new year's resolutions in the general workforce is to either get a new job or work to further develop one's career. I think this is a good idea, in today's competitive work force people should have a plan of what they want to do, what role they are after and how to get there. One common mistake I think many people make though is that a career plan shouldn't be a once a year thought. When people finish with the holiday season with their new year's resolution to find a new job fresh in their mind, you can see the enthusiasm and motivation a person has to make something happen. Emails are sent, calls are made, applications are made, networking is happening, etc..... Finding the right role that you are after however can be difficult, while it would be great if that dream role was available just at the time you happened to be looking for it - in reality this is not always the case. Job Seekers need to keep reminding themselves that while sometimes that dream job they are after is available at the same time they are looking, that also a Job search can be a difficult and long process. Many people who set out with the best of intentions in January to find a new job can soon lose interest in a job search if they do not immediately find a role. Just like the Christmas decorations are put away and the photos from New Year's are stored away - a Job Seeker's motivation may slowly decrease until that person finds themselves 12 months later in the same situation in same role and looking for that new opportunity again. Rather than just "going for it" and looking for a role in the month of January, a person's job search or career plan should be an ongoing activity and thought process that is constantly updated and evaluated over the course of the year. It can be hard to stay motivated over an extended period of time, especially when you are newly motivated and ready for that new role and the results are not immediate. Rather than letting your job search fall down the priority list and into the "too hard basket" a few ideas that may keep your enthusiasm fresh Update your resume every 6 months, even if you are not looking for a job - it is easy to forget what you have accomplished if you don't keep your details updated. Also it is good to be prepared and have a resume ready to go in case you do get an unexpected phone call for that 'dream job' you have been hoping for. Work out what you want out of your next role before you begin your job search - rather than aimlessly searching job ads or talking to people - think of the organisations or type of role you would like before you search. If you know what you are looking for it will be much easier to work out how to get there than if you do not know what you want. Don't expect immediate results once you decide to look for another job, things don't always fall into place. Timing and delivery can be important pieces of being selected for a role, companies don't hire every role in January. Have an open mind - people you meet or talk to may not result in immediate results for your job search but every connection may help you get a bit closer to what you are after . These actions will not guarantee a positive result, but in today's competitive work force every little of extra preparation and planning helps. All the best for 2011 and I hope your career plan whatever it may be is a success.

• Visual Studio 2010 SP1

  - by ScottGu

  Last week we shipped Service Pack 1 of Visual Studio 2010 and the Visual Studio Express Tools.  In addition to bug fixes and performance improvements, SP1 includes a number of feature enhancements.  This includes improved local help support, IntelliTrace support for 64-bit applications and SharePoint, built-in Silverlight 4 Tooling support in the box, unit testing support when targeting .NET 3.5, a new performance wizard for Silverlight, IIS Express and SQL CE Tooling support for web projects, HTML5 Intellisense for ASP.NET, and more.  TFS 2010 SP1 was also released last week, together with a new TFS Project Server Integration Pack and Load Test Feature Pack.  Brian Harry has a good blog post about the TFS updates here. VS 2010 SP1 Download Click here to download and install SP1 for all versions of Visual Studio (including express).  This installer examines what you have installed on your machine, and only downloads the servicing downloads necessary to update them to SP1.  The time it takes to download and update will consequently depend on what all you have installed.  Jon Galloway has a good blog post on tips to speed up the SP1 install by uninstalling unused components. Web Platform Installer Bundles In addition to the core VS 2010 SP1 installer, we have also put together two Web Platform Installer (WebPI) bundles that automate installing SP1 together with additional web-specific components: VS 2010 SP1 WebPI Bundle Visual Web Developer 2010 SP1 WebPI Bundle The above WebPI bundles automate installing: VS 2010/VWD 2010 SP1 ASP.NET MVC 3 (runtime + tools support) IIS 7.5 Express SQL Server Compact Edition 4.0 (runtime + tools support) Web Deployment 2.0 Only the components that are not already installed on your machine will be downloaded when you use the above WebPI bundles.  This means that you can run the WebPI bundle at any time (even if you have already installed SP1 or ASP.NET MVC 3) and not have to worry about wasting time downloading/installing these components again. Earlier this year I did two posts that discussed how to use IIS Express and SQL CE with ASP.NET projects in SP1.  Read the below posts to learn more about how to use them after you run the above bundles: Visual Studio 2010 SP1 and IIS Express Visual Studio 2010 SP1 and SQL CE for ASP.NET The above feature additions work with any web project type – including both ASP.NET Web Forms and ASP.NET MVC. Additional SP1 Notes Two additional notes about VS 2010 SP1: 1) One change we made between RTM and SP1 is that by default Visual Studio now uses software rendering instead of hardware acceleration when running on Windows XP.  We made this change because we’ve seen reports of (often inconsistent) performance issues caused by older video drivers.  Running in software mode eliminates these and delivers consistent speeds.  You can optionally re-enable hardware acceleration with SP1 using Visual Studio’s Tools->Options menu command – we did not remove support for HW acceleration on XP, we simply changed the default setting for it.  Jason Zander has written more details on the change and how to re-enable HW acceleration inside VS here. 2) We have discovered an issue where installing SP1 can cause TSQL intellisense within SQL Server Management Studio 2008 R2 to stop working (typing still works – but intellisense doesn’t show up).  The SQL team is investigating this now and I’ll post an update on how to fix this once more details are known.  Hope this helps, Scott P.S. I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• Great Customer Service Example

  - by MightyZot

  A few days ago I wrote about what I consider a poor customer service interaction with TiVo, a company that I have been faithful to for the past 12 years or so. In that post I talked about how they helped me, but I felt like I was doing something wrong at the end of the call – when in reality I was just following through with an offer that TiVo made possible through my cable company. Today I had a wonderful customer service interaction with American Express, another company that I have been loyal to for many years.(I am a Gold Card member.) I like my Amex card because I can use it for big purchases and it forces me to pay them off at the end of the month. Well, the reality is that I’m not always so good at doing that, so sometimes my payments are over a couple of months.  :) A few days ago I received an email from “American Express” fraud detection. The email stated that I should call a toll free number and have the last four digits of my card handy. I grew up during the BBS era with some creative and somewhat mischievous friends. I’ve learned to be extremely cautious with regard to my online life! So, I did what you would expect…I sent them a nice reply that said “Go screw yourself.” For the past couple of days someone has been trying to call me and I assumed it was the same prankster trying to get the last four digits of my card. The last caller left a message indicating that they were from American Express and they wanted to talk to me about my card. After looking up their customer service numbers on the www.americanexpress.com web site, I called and was put through to the fraud detection group. The rep explained that there were some charges on my wife’s card that did not fit our purchase profile. She went through each charge and, for the most part, they looked like charges my wife may have made. My wife had asked to use the card for some Christmas shopping during the same timeframe as the charges. The American Express rep very politely explained that these looked out of character to her. She continued through the charges. She listed a charge for $160 – at this point my adrenaline started kicking in. My wife said she was going to charge about $25 or $30 dollars, not $160. Next, the rep listed a charge for over $1200. Uh oh!! Now I know that my account has been compromised. I informed the rep that we definitely did not make those charges. She replied with, “that’s ok Mr Pope, we declined those charges as well as some others.” We went through the pending charges and there were a couple more that were questionable. The rep very patiently waited while I called my wife on my office phone to verify the charges. Sure enough, my wife had not ordered anything from Netflix or purchased anything with Yahoo Wallet! “No problem Mr Pope, we will remove those charges as well.” “We are going to cancel your wife’s card and send her a new one. She will receive it by 7pm tomorrow via Federal Express. Please watch your statements over the next couple of months. If you notice anything fishy, give us a call and we will take care of it for you.” (Wow, I’m thinking to myself!) “Is there anything else I can help you with Mr Pope?” “Nope, thank you very much for catching this so early and declining those charges!”, I said smiling. Apparently she could hear me smiling on the other end of the phone line because she replied with “keep smiling Mr Pope and have a good rest of your week.” Now THAT’s customer service!  Thank you American Express!!! I shall remain an ever faithful customer. Interesting…

• How to prepare for an interview presentation!

  - by Tim Koekkoek

  During an interview process you might be asked to prepare a presentation as one of the steps in the recruitment process. Below, we want to give you some tips to help you prepare for what might be considered a daunting aspect of a recruitment process. Main purpose of the presentation Always keep in mind the main purpose of what the presentation is meant to convey. Generally speaking, an interview presentation is for the company to check if you have the ability to represent and sell the organization (and yourself), to the internal and external stakeholders in the position you are applying for. A presentation is often also part of the recruitment process to check whether you can structure and explain your experience and thoughts in a convincing manner. If you are unsure about the purpose of the presentation, feel free to ask your recruiter for more information. Preparation As with every task you do, preparation is key, so is the case with an interview presentation. It is important to know who your audience is. You have to adapt your presentation to your audience, ensuring that you are presenting the facts which they would want to hear. Furthermore, make sure you practice your presentation beforehand; this will make you more confident in your presenting skills. Also, estimate the length of your presentation as presentations or pitches during the recruitment process are often capped to a certain time limit. Structure Every presentation should have a beginning, middle and an end. Make sure you give an overview of your presentation and tell the audience what they can expect. Your presentation should have a logical order and a clear message. Always build up to your key message with strong arguments and evidence. When speaking about the topic, make sure you convey your points with conviction. Also be sure you believe the message you bring forward, if you don’t believe it yourself, then the audience definitely won’t! Delivery When you think back on successful presentations you have seen, the presenter was most likely always standing up. So if asked to do a presentation, follow this example and make sure you stand up as well. Standing up when you are doing your presentation shows confidence and control. Another important aspect in the delivery of the presentation is to relax and speak slowly and with enough volume for the audience to hear you. Speaking slowly allows the audience the time to absorb the information you are providing to them. Visual Using PowerPoint, or an equivalent, makes it very easy to have a visually attractive presentation. Make sure however that you take into account that the visual aids you use are there to support you, not for you to read word for word what is on the slides! Questions When starting your presentation, it is a good idea to tell your audience that you will deal with any questions they might have at the end of the presentation. This way it doesn’t interrupt your train of thought and the flow of your presentation. Answering questions at the end may give you additional opportunities to further expand on your facts in the topic. Some people might play the “devil’s advocate” role and confront you with opposing opinions, if this is the case, take your time to reiterate your points and remain professional in your response. A good way to deal with this is to start interacting with other members of the audience and ask for their opinions, so it will become a group discussion. This will also shows strong leadership skills, as you are open to discuss and ask for other opinions.

• Odd MVC 4 Beta Razor Designer Issue

  - by Rick Strahl

  This post is a small cry for help along with an explanation of a problem that is hard to describe on twitter or even a connect bug and written in hopes somebody has seen this before and any ideas on what might cause this. Lots of helpful people had comments on Twitter for me, but they all assumed that the code doesn't run, which is not the case - it's a designer issue. A few days ago I started getting some odd problems in my MVC 4 designer for an app I've been working on for the past 2 weeks. Basically the MVC 4 Razor designer keeps popping me errors, about the call signature to various Html Helper methods being incorrect. It also complains about the ViewBag object and not supporting dynamic requesting to load assemblies into the project. Here's what the designer errors look like: You can see the red error underlines under the ViewBag and an Html Helper I plopped in at the top to demonstrate the behavior. Basically any HtmlHelper I'm accessing is showing the same errors. Note that the code *runs just fine* - it's just the designer that is complaining with Errors. What's odd about this is that *I think* this started only a few days ago and nothing consequential that I can think of has happened to the project or overall installations. These errors aren't critical since the code runs but pretty annoying especially if you're building and have .csHtml files open in Visual Studio mixing these fake errors with real compiler errors. What I've checked Looking at the errors it indeed looks like certain references are missing. I can't make sense of the Html Helpers error, but certainly the ViewBag dynamic error looks like System.Core or Microsoft.CSharp assemblies are missing. Rest assured they are there and the code DOES run just fine at runtime. This is a designer issue only. I went ahead and checked the namespaces that MVC has access to in Razor which lives in the Views folder's web.config file: /Views/web.config For good measure I added <system.web.webPages.razor> <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, <split for layout> Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <pages pageBaseType="System.Web.Mvc.WebViewPage"> <namespaces> <add namespace="System.Web.Mvc" /> <add namespace="System.Web.Mvc.Ajax" /> <add namespace="System.Web.Mvc.Html" /> <add namespace="System.Web.Routing" /> <add namespace="System.Linq" /> <add namespace="System.Linq.Expressions" /> <add namespace="ClassifiedsBusiness" /> <add namespace="ClassifiedsWeb"/> <add namespace="Westwind.Utilities" /> <add namespace="Westwind.Web" /> <add namespace="Westwind.Web.Mvc" /> </namespaces> </pages> </system.web.webPages.razor> For good measure I added System.Linq and System.Linq.Expression on which some of the Html.xxxxFor() methods rely, but no luck. So, has anybody seen this before? Any ideas on what might be causing these issues only at design time rather, when the final compiled code runs just fine?© Rick Strahl, West Wind Technologies, 2005-2012Posted in Razor  MVC   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Lazy Evaluation &ndash; Why being lazy in F# blows my mind!

  - by MarkPearl

  First of all – shout out to Peter Adams – from the feedback I have gotten from him on the last few posts of F# that I have done – my mind has just been expanded. I did a blog post a few days ago about infinite sequences – I didn’t really understand what was going on with it, and I still don’t really get it – but I am getting closer. In Peter’s last comment he made mention of Lazy Evaluation. I am ashamed to say that up till then I had never heard about lazy evaluation – how can evaluation be lazy? I mean, I know about lazy loading and that makes sense… but surely something is either evaluated or not! Well… a bit of reading today and I have been enlightened to a point – if you do know of any good articles explaining lazy evaluation please send them to me. So what is lazy evaluation and why is it useful? Lazy evaluation is a process whereby the system only computes the values needed and “ignores” the computations not needed. I’m going out on a limb here, but with this explanation in hand, imagine the following C# code… public int CalculatedVal() { int Val1 = 0; int Val2 = 0; for (int Count = 0; Count < 1000000; Count++) { Val1++; } return Val2; }   Normally, even though Val1 is never needed, the system would loop 1000000 times and add 1 to the current value of Val1. Imagine if the system realized this and so just skipped this segment of code and instead did the following…. public int CalculatedVal() { int Val1 = 0; return Val2; }   A massive saving in computation and wasted effort. Now I am pretty sure it isn’t as simple as this but I think this is the basic idea. For a more detailed explanation of lazy evaluation in c#, Pedram Rezei has a wonderful post on lazy evaluation and makes some C# comparisons. I am not going to take any thunder from him by repeating everything he said since I think he did such a good job of explaining it himself. What I am interested in though is how in F# do you tell something to have lazy evalution, and how do you know if something will be eager or lazy by looking at it. I found this post was useful. From reading around F# by default uses eager evaluation unless explicitly told to use lazy evaluation. One exception to this is sequences, which are lazy by default. Now reading about lazy evaluation has helped me understand more about F# coding… From my understanding of F# because of its declarative nature, most of the actual code you are declaring properties and rules – very little code is actually saying do this right now - but when it comes to a “do this” code section, it then evaluates and optimizes code and applies the rules. So props to lazy evaluation and its optimizations…

• To sample or not to sample...

  - by [email protected]

  Ideally, we would know the exact answer to every question. How many people support presidential candidate A vs. B? How many people suffer from H1N1 in a given state? Does this batch of manufactured widgets have any defective parts? Knowing exact answers is expensive in terms of time and money and, in most cases, is impractical if not impossible. Consider asking every person in a region for their candidate preference, testing every person with flu symptoms for H1N1 (assuming every person reported when they had flu symptoms), or destructively testing widgets to determine if they are "good" (leaving no product to sell). Knowing exact answers, fortunately, isn't necessary or even useful in many situations. Understanding the direction of a trend or statistically significant results may be sufficient to answer the underlying question: who is likely to win the election, have we likely reached a critical threshold for flu, or is this batch of widgets good enough to ship? Statistics help us to answer these questions with a certain degree of confidence. This focuses on how we collect data. In data mining, we focus on the use of data, that is data that has already been collected. In some cases, we may have all the data (all purchases made by all customers), in others the data may have been collected using sampling (voters, their demographics and candidate choice). Building data mining models on all of your data can be expensive in terms of time and hardware resources. Consider a company with 40 million customers. Do we need to mine all 40 million customers to get useful data mining models? The quality of models built on all data may be no better than models built on a relatively small sample. Determining how much is a reasonable amount of data involves experimentation. When starting the model building process on large datasets, it is often more efficient to begin with a small sample, perhaps 1000 - 10,000 cases (records) depending on the algorithm, source data, and hardware. This allows you to see quickly what issues might arise with choice of algorithm, algorithm settings, data quality, and need for further data preparation. Instead of waiting for a model on a large dataset to build only to find that the results don't meet expectations, once you are satisfied with the results on the initial sample, you can  take a larger sample to see if model quality improves, and to get a sense of how the algorithm scales to the particular dataset. If model accuracy or quality continues to improve, consider increasing the sample size. Sampling in data mining is also used to produce a held-aside or test dataset for assessing classification and regression model accuracy. Here, we reserve some of the build data (data that includes known target values) to be used for an honest estimate of model error using data the model has not seen before. This sampling transformation is often called a split because the build data is split into two randomly selected sets, often with 60% of the records being used for model building and 40% for testing. Sampling must be performed with care, as it can adversely affect model quality and usability. Even a truly random sample doesn't guarantee that all values are represented in a given attribute. This is particularly troublesome when the attribute with omitted values is the target. A predictive model that has not seen any examples for a particular target value can never predict that target value! For other attributes, values may consist of a single value (a constant attribute) or all unique values (an identifier attribute), each of which may be excluded during mining. Values from categorical predictor attributes that didn't appear in the training data are not used when testing or scoring datasets. In subsequent posts, we'll talk about three sampling techniques using Oracle Database: simple random sampling without replacement, stratified sampling, and simple random sampling with replacement.

• A debugging experience with "highly compatible" ASP.NET 4.5

  - by Jeff

  I have to admit that I will pretty much upgrade software for no reason other than being on the latest version. I won't do it if it's super expensive (Adobe gets money from me about once every three or four years at best), but particularly with frameworks and stuff generally available as part of my MSDN subscription, I'll be bleeding edge. CoasterBuzz was running on the MVC 4 framework pretty much as soon as they did a "go live" license for it. I didn't really jump in head-first with Windows 8 and Visual Studio 2012, in part because I just wasn't interested in doing the reinstalls for each new version. Turns out there weren't that many revisions anyway. But when the final versions were released a week and a half ago, I jumped in. I saw on one of the Microsoft sites that .Net 4.5 was a "highly compatible in-place update" to the framework. Good enough for me. I was obviously running it by default in Windows 8, and installed it on my production server. I suppose it's "highly compatible," except when it isn't. Three of my sites are running with various flavors of the MVC version of POP Forums. All of them stopped working under ASP.NET 4.5. It was not immediately obvious what the problem might be beyond an exception indicating that there were no repository classes registered with Ninject, which I use for dependency injection in the forums. This was made all the more weird by the fact that it ran fine locally in the dev Web host. My first instinct was to spin up a Windows Server VM on my local box and put the remote debugger on it. (Side note: running multiple VM's on a Retina MacBook Pro with 16 gigs of RAM is pretty much the most awesome thing ever. I can't believe this computer is for real, and not a 50-pound tower under my desk.) What might have been going on in IIS that doesn't happen in Visual Studio? In the debugging process, I realized that I might be looking in the wrong place. POP Forums creates a Ninject container using a method called from a PreApplicationStartMethod attribute, and at that time registers a module (what Ninject uses to map interfaces to implementations) that maps all of the core dependencies. It also creates an instance of an HttpModule that originally hosted the "services" (search indexing, mailer, etc.), but now just records errors. That's all well and good, but the actual repository mapping, where data is actually read or persisted, happens in Application_Start() in global.asax. The idea there is that you can swap out the SqlSingleWebServer repos for something tuned for multiple servers, Oracle or something else. Of course, if I used something like StructureMap, which does convention-based mapping for dependency injection (a class implementing ISettingsRepository called SettingsRepository is automagically mapped), I wouldn't have to worry about it. In any case, the HttpModule, being instantiated before Application_Start() gets to run, would throw because there was no repo mapped where it could get settings from the database. This makes total sense. The fix is sort of a hack, where I don't setup the innards of the HttpModule until a call to its BeginRequest is made. I say it's a hack, because its primary function, logging exceptions, won't work until the app has warmed up. Still, this brings up an interesting question about the race condition, and what changed in 4.5 when it's running in IIS. In ASP.NET 4, it would appear that the code called via the PreApplicationStartMethod was either failing silently, and running again later, or it was getting to that code after Application_Start was called. In any case, weird thing. The real pain point I'm experiencing now is a bug in MVC 4 that is extremely serious because it renders the mobile/alternate view functionality very much broken.

• Create Custom Windows Key Keyboard Shortcuts in Windows

  - by Asian Angel

  Nearly everyone uses keyboard shortcuts of some sort on their Windows system but what if you could create new ones for your favorite apps or folders? You might just be amazed at how simple it can be with just a few clicks and no programming using WinKey. WinKey in Action During the installation process you will see this window that gives you a good basic idea of just what can be accomplished with this wonderful little app. As soon as the installation process has finished you will see the “Main App Window”. It provides a simple straightforward listing of all the keyboard shortcuts that it is currently managing. Note: WinKey will automatically add an entry to the “Startup Listing” in your “Start Menu” during installation. To see the regular built-in Windows keyboard shortcuts that it is managing click “Standard Shortcuts” to select it and then click on “Properties”. For those who are curious WinKey does have a “System Tray Icon” that can be disabled if desired. Now onto creating those new keyboard shortcuts… For our example we decided to create a keyboard shortcut for an app rather than a folder. To create a shortcut for an app click on the small “Paper Icon” as shown here. Once you have done that browse to the appropriate folder and select the exe file. The second step will be choosing which keyboard shortcut you would like to associate with that particular app. You can use the drop-down list to choose from a listing of available keyboard combinations. For our example we chose “Windows Key + A”. The final step is choosing the “Run Mode”. There are three options available in the drop-down list…choose the one that best suits your needs. Here is what our example looked like once finished. All that is left to do at this point is click “OK” to finish the process. And just like that your new keyboard shortcut is now listed in the “Main App Window”. Time to try out your new keyboard shortcut! One quick use of our new keyboard shortcut and Iron Browser opened right up. WinKey really does make creating new keyboard shortcuts as simple as possible. Conclusion If you have been wanting to create new keyboard shortcuts for your favorite apps and folders then it really does not get any simpler than with WinKey. This is definitely a recommended app for anyone who loves “get it done” software.

• Friday Fun: Spell Blazer

  - by Asian Angel

  Are you ready for some fun and adventure after a long week back at work? This week’s game combines jewel-matching style game play with an RPG story for an awesome mix of fun and fiction. Your goal is to help a young wizard reach the magic academy in Raven as the forces of darkness are building. Spell Blazer The object of the game is to help young Kaven reach the Lightcaster Academy in Raven alive, but he will encounter many dangers along the way. Are you ready to begin the quest? As soon as you click Start Game the intro will automatically begin. If this is your first time playing the game the intro provides a nice background story for the game and what is happening in the game environment. Once you are past the intro, you will see a map of the region with your starting point in the Farmlands, various towns and the roads connecting them, along with your final destination of Raven. Notice that some of the roads are different colors…those colors indicate the “danger levels” for each part of your journey (green = good, yellow = some danger, etc.). To begin your journey click on the Town of Goose with your mouse. You will encounter your first monster part of the way towards Goose. This first round takes you through the game play process step-by-step. Once you have clicked Okay you will see the details about the monster you have just encountered. It is very important that you do not click on Fight! or Flee! until viewing and noting the types of spells that the monster is resistant to or has a weakness against. Choose your spells wisely based on the information provided about the monster. Keep in mind that the healing spell can be very useful depending on the monster you meet and your current health status. Note: Spells shown in order here are Healing, Fireball, Icebolt, & Lightning. Ready to fight! The first battle will also explain how to fight…click Okay to get started. Once the main window is in full view there are details that you need to look at. Beneath each of the combatants you will see the three attacks that each brings to the battle and at the bottom you will see their respective health points. We got lucky and had an Icebolt attack that we could utilize on the first play! Note: You can exchange two squares without making a match in order to try and line up an attack. While it happened too quickly to capture in our screenshot, there will be cool lightning bolt effects shoot out from matched up squares to the opposite combatant. You will also see the amount of damage inflicted from a particular attack on top of the avatars. Victory! Once you have won a round of combat a window will appear showing the amount of gold coins left behind by the monster. When you reach a town you will have the opportunity to stop over and rest or directly continue on with your journey. On to Halgard after a good rest!

• Microsoft ReportViewer SetParameters continuous refresh issue

  - by Ilya Verbitskiy

  Originally posted on: http://geekswithblogs.net/ilich/archive/2013/10/16/microsoft-reportviewer-setparameters-continuous-refresh-issue.aspxI am a big fun of using ASP.NET MVC for building web-applications. It allows us to create simple, robust and testable solutions. However, .NET world is not perfect. There is tons of code written in ASP.NET web-forms. You cannot simply ignore it, even if you want to. Sometimes ASP.NET web-forms controls bring us non-obvious issues. The good example is Microsoft ReportViewer control. I have an example for you. 1: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> 2: <%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %> 3:   4: <!DOCTYPE html> 5:   6: <html xmlns="http://www.w3.org/1999/xhtml"> 7: <head runat="server"> 8: <title>Report Viewer Continiuse Resfresh Issue Example</title> 9: </head> 10: <body> 11: <form id="form1" runat="server"> 12: <div> 13: <asp:ScriptManager runat="server"></asp:ScriptManager> 14: <rsweb:ReportViewer ID="_reportViewer" runat="server" Width="100%" Height="100%"></rsweb:ReportViewer> 15: </div> 16: </form> 17: </body> 18: </html>   The back-end code is simple as well. I want to show a report with some parameters to a user. 1: protected void Page_Load(object sender, EventArgs e) 2: { 3: _reportViewer.ProcessingMode = ProcessingMode.Remote; 4: _reportViewer.ShowParameterPrompts = false; 5:   6: var serverReport = _reportViewer.ServerReport; 7: serverReport.ReportServerUrl = new Uri("http://localhost/ReportServer_SQLEXPRESS"); 8: serverReport.ReportPath = "/Reports/TestReport"; 9:   10: var reportParameter1 = new ReportParameter("Parameter1"); 11: reportParameter1.Values.Add("Hello World!"); 12:   13: var reportParameter2 = new ReportParameter("Parameter2"); 14: reportParameter2.Values.Add("10/16/2013"); 15:   16: var reportParameter3 = new ReportParameter("Parameter3"); 17: reportParameter3.Values.Add("10"); 18:   19: serverReport.SetParameters(new[] { reportParameter1, reportParameter2, reportParameter3 }); 20: }   I set ShowParametersPrompts to false because I do not want user to refine the search. It looks good until you run the report. The report will refresh itself all the time. The problem caused by ServerReport.SetParameters method in Page_Load. The method cause ReportViewer control to execute the report on the NEXT post back. That is why the page has continuous post-backs. The fix is very simple: do nothing if Page_Load method executed during post-back. 1: protected void Page_Load(object sender, EventArgs e) 2: { 3: if (IsPostBack) 4: { 5: return; 6: } 7:   8: _reportViewer.ProcessingMode = ProcessingMode.Remote; 9: _reportViewer.ShowParameterPrompts = false; 10:   11: var serverReport = _reportViewer.ServerReport; 12: serverReport.ReportServerUrl = new Uri("http://localhost/ReportServer_SQLEXPRESS"); 13: serverReport.ReportPath = "/Reports/TestReport"; 14:   15: var reportParameter1 = new ReportParameter("Parameter1"); 16: reportParameter1.Values.Add("Hello World!"); 17:   18: var reportParameter2 = new ReportParameter("Parameter2"); 19: reportParameter2.Values.Add("10/16/2013"); 20:   21: var reportParameter3 = new ReportParameter("Parameter3"); 22: reportParameter3.Values.Add("10"); 23:   24: serverReport.SetParameters(new[] { reportParameter1, reportParameter2, reportParameter3 }); 25: } You can download sample code from GitHub - https://github.com/ilich/Examples/tree/master/ReportViewerContinuousRefresh
