  • Repeater vs. ListView

    - by MoezMousavi
    I do really hate repeater. I was more a GridView lover but after 3.5 be born, I prefer ListView.  The first problem with Repeater is paging. You will need to write code to handle paging. Second common problem is empty data template. Have a look at this:             if (rptMyRepeater.Items.Count < 1)             {                 if (e.Item.ItemType == ListItemType.Footer)                 {                     Label lblFooter = (Label)e.Item.FindControl("lblEmpty");                     lblFooter.Visible = true;                 }             }   I found the above code is usefull if you need to show something like "There is no record" is your data source has no records. Although the ListView has a template.   If you combine ListView with a DataPager, you will be in heaven as it is sorting the paging for you without writing code. (http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.datapager.aspx)     Note: You have got to bind ListView in PreRender, it doesn't work properly in PageLoad   More: http://www.4guysfromrolla.com/articles/061009-1.aspx

  • Facebook likes reset after moving to HTTPS (URL manually set in script, though)

    - by aarondicks
    Hi fellow Facebook developers. I've got a question regarding the Facebook like button. We worked on a piece recently that embeds a number of social share buttons (please see the source code below or here on Harvey Water Softeners' website) When the piece was released, it was on HTTP, and received over 2k likes (the URL 'slug' hasn't changed at all). The site was recently migrated to permanent-on HTTPS, and the like data has been reset, and we've been left with 50 new, recent likes. If you see in the source code, the URL is set explicitly to like the HTTP version, which I believe to be correct. Can anyone help me work out what's happened here? Here's the HTML bit of the like button: <div class="fb-like" data-href="http://www.harveywatersofteners.co.uk/history-interior-design" data-layout="box_count" data-action="like" data-show-faces="false" data-share="false"></div> Thanks in advance Aaron

  • How to test 3d acceleration?

    - by HappyDeveloper
    I want to install and test 3d acceleration in Ubuntu 12. I have read these pages: https://help.ubuntu.com/community/RadeonDriver https://wiki.ubuntu.com/X/Troubleshooting/VideoDriverDetection?action=show&redirect=X%2FTroubleshooting%2FFglrxInteferesWithRadeonDriver#Problem:_Need_to_purge_-fglrx I think I have installed it correctly, but I don't know how to test it. I tried to play minecraft in the browser, but I got a black screen. It may be a java problem too, so I need to troubleshoot. So how can I test my video card and drivers?

  • Why do I have Unity and GNOME Classic running at the same time?

    - by jerowin
    I've recently updated and found that Unity shows on the gnome-classic/fallback desktop. Is this a new feature (which I doubt to be), or a bug? If it is a bug, tell me how to disable Unity because it interferes with the lower panel (i.e. I bring out Trash instead of showing the desktop when I try pressing the "Show desktop" button when the panel is not in focus). I don't encounter this problem in gnome-classic (No effects). Don't judge me. I like pokemon!

  • UDK : UTWeap_RocketLauncher gift CreateInventory: Any idea why this does not work properly?

    - by John Sloan
    I am giving the player an instanced class of UTWeap_RocketLauncher in an instance of UTGame. PlayerPawn.CreateInventory(class'FobikRocketLauncher',false); // Does not work PlayerPawn.CreateInventory(class'FobikLinkGun',false); // Works Even if I give the original class (eg. UTWeap_RocketLauncher) it does not actually show up. However if I do a "GiveWeapons" cheat, I get it just fine. It also works if I had code it into the map. - But UTWeap_LinkGun works fine either way. Any ideas? It shows the default ammo amount, and the icon on the HUD.

  • Windows Phone 8 Launch Event Summary

    - by Tim Murphy
    Today was the official coming out party for Windows Phone 8.  Below is a summary of the launch event.  There is a lot here to stay with me. They started with a commercial staring Joe Belfiore show how his Windows Phone 8 was personal too him which highlights something I think Microsoft has done well over the last couple of event: spotlight how Windows Phone is a different experience from other smartphones.  Joe actually called iPhone and Android “tired old metaphors" and explained that the idea around Windows Phone was to “reinvent the smartphone around you” as “the most personal smartphone operating system”.  The is the message that they need to drive home in their adds. The only real technical aspect we found out was that they have optimized the operating system around the dual core Qualcomm Snapdragon chip set.  It seems like all of the other hardware goodies had already been announced.  The remainder of the event was centered around new features of the OS and app announcements. So what are we getting?  The integrated features included lock screen live tile, Data Sense, Rooms and Kids corner.  There wasn’t a lot of information about it, but Joe also talked about apps not just having live tiles, but being live apps that could integrate with wallet and the hub. The lock screen will now be able to be personalized with live tile data or even a photo slide show.  This gives the lock screen an even better ability to give you the information you want to know before you even unlock the phone. The Kids Corner allows you as a parent to setup an area on your phone that you kids can go into an use it without disturbing your apps.  They can play games or use apps that you have designated and will only see those apps.  It even has a special lock screen gesture just for the kids corner. Rooms allow you to organize your phone around the groups of people in your life.  You get a shared calendar, a room wall as well as shared notes beyond just being able to send messages to a group.  You can also invite people not on the Windows Phone platform to access an online version of the room. Data Sense is a new feature that gives you better control and understanding of your data plan usage.  You can see which applications are using data and it can automatically adjust they way your phone behaves as you get close to your data limit. Add to these features the fact that the entire Windows ecosystem is integrated with SkyDrive and you have an available anywhere experience that is unequaled by any other platform.  Your document, photos and music are available on your Windows Phone, Window 8 device and Xbox.  SkyDrive also doesn’t limit how long you can keep files like the competing cloud platforms and give more free storage. It was interesting the way they made the launch event more personal.  First Joe brought out his own kids to demo the Kids Corner.  They followed this up by bringing out Jessica Alba to discuss her experience on the Windows Phone 8.  They need to keep putting a face on the product instead of just showing features as a cold list. Then we get to apps.  We knew that the new Skype was coming, but we found out that it was created in such a way that it can receive calls without running consistently in the background which would eat up battery.  This announcement was follow by the coming Facebook app that is optimized for Windows Phone 8.  As a matter of fact they indicated that just after launch the marketplace would have 46 out of the top 50 apps used by all smartphone platforms.  In a rational world this tide with over 120,000 apps currently in the marketplace there should be no more argument about the Windows Phone ecosystem. For those of us who develop for Windows Phone and weren’t on the early adoption program will finally get access to the SDK tomorrow after an announcement at Build (more waiting).  Perhaps we will get a few new features then. In the end I wouldn’t say there were any huge surprises, but I am really excited about getting my hands on the devices next month and starting to develop.  Stay tuned. del.icio.us Tags: Windows Phone,Windows Phone 8,Winodws Phone 8 Launch,Joe Belfiore,Jessica Alba

  • Collision representation in game overworlds

    - by Akroy
    I'm implementing a 2D overworld where one can walk through an area that is not tile based. I was wondering the best way to implement collisions. In the past when I've done similar things, I've used one image (or set of images) to show an elaborately drawn world and then a second binary image that does nothing but differentiate "wall" and "not wall". Then, I'd use the first for all drawing to the screen, but the second for collision detection. Having another image of the same size to represent collisions seems like lots of overhead. Is there a better way to handle this? (I'm currently using C++ with SDL, although I'm more interested in general concepts)

  • JavaOne 2012 demo of Java SE Embedded on Raspberry Pi

    - by hinkmond
    Here's the Inquirer's article about our Java SE Embedded demos at JavaOne 2012 this year. Simon Ritter had a fun presentation showing the cool demo on the Raspberry Pi at his talk. See: Demo Java SE Embedded on Raspberry Pi Here's a quote: Oracle demonstrated Java SE for embedded devices running on the Raspberry Pi bare bones computer at the Java One show on Wednesday, with the aim of encouraging developers to try it out for themselves to create reference libraries for the target school children audience. I had the presentation after Simon and saw the size crowd he had. They were laughing and clapping at the demo and having a good ol' time. Good to see the interest in Java SE Embedded, even if it is for a "toy" device like the Raspberry Pi. Hinkmond

  • What's the point of Rabbit MQ? [duplicate]

    - by bad_boy
    This question already has an answer here: When to use Advanced Message Queuing Protocol like RabbitMQ? [closed] 2 answers First of all, let me say, I have no problem following tutorials. The problem is that I don't understand why even Rabbit MQ is ever needed. And there's no such explanation on tutorials - they only show what to do and how to use, but not when its usage is the case. Can you explain this? Why would you want to use Rabbit MQ? To solve what problem?

  • How to install an additional .NET library?

    - by Deusdies
    I'm a beginner .NET programmer (C# and IronPython). I've come across WatiN .NET library which will show handy for what I'm trying to do. The website claims that it is compatible with any .NET language, so I assume it's compatible with IronPython as well. How do I go about installing it? Their website only has some instructions, using NUget in Visual Studio. I neither use Visual Studio nor am I interested in it. How and where would I put the downloaded files in order to make it work with IronPython?

  • Showing "Failed" for a SharePoint 2010 Timer Job Status

    - by Damon
    I have been working with a bunch of custom timer jobs for last month.  Basically, I'm processing a bunch of SharePoint items from the timer job and since I don't want the job failing because of an error on one item, so I'm handing errors on an item-by-item basis and just continuing on with the next item.  The net result of this, I soon found, is that my timer job actually says it ran successfully even if every single item fails.  So I figured I would just set the "Failed" status on the timer job is anything went wrong so an administrator could see that not all was well. However, I quickly found that there is no way to set a timer job status.  If you want the status to show up as "Failed" then the only way to do it is to throw an exception.  In my case, I just used a flag to store whether or not an error had occurred, and if so the the timer job throws a an exception just before existing to let the status display correctly.

  • juju: How do I list all the relation variables and debug them interactively?

    - by mfisch
    I'm writing a charm that requires a mysql database, I found from looking at other charms that this (below) is how I get the info about the database: user=`relation-get user` password=`relation-get password` mysqlhost=`relation-get private-address` But I just found that from reading the wordpress charm example, is there a way to show all the relation variables that I can use? Also, while debugging my db-relation-changed script, I wanted to ssh into my host and interactively run those commands, for example relation-get user, but it didn't work. I resorted to having to restart everything and use juju log to print them out. This wasted a lot of time. Is there a way to print out these relations, either from my dev box or from the instance running my charm? (Below is what happens when I tried to interactively run relation-get): ubuntu@mfisch-local-tracks-0:~$ relation-get user usage: relation-get [-h] [-o OUTPUT] [-s SOCKET] [--client-id CLIENT_ID] [--format FORMAT] [--log-file FILE] [--log-level CRITICAL|DEBUG|INFO|ERROR|WARNING] [-r RELATION ID] [settings_name] [unit_name] No JUJU_AGENT_SOCKET/-s option found

  • Finish long directory name with tab problem

    - by user1880405
    I have simple problem that I have to long directories which I want to cd into, but I would like to know easy way. mosquito@mosquito-K56CB:~/Downloads$ ls | grep Guns Guns n' Roses - Appetite for Destruction (Japanese Edition) 1987 Guns n' Roses - Use Your Illusion I 1991 Of course I can just copy the name and put it like this: cd "Guns n' Roses - Appetite for Destruction (Japanese Edition) 1987" But why when I write cd Guns then tab, it finishes line into: cd Guns\ n\'\ Roses\ -\ then by my understanding I should just start writing App.. with tab and it should finish whole name, but it does not. And hitting tab twice does not show me anything either. What I am missing here?

  • Lining things up while using columns

    - by Charles
    I have a request that may not be possible. I'd like to line up the elements of a form so that the inputs all start at the same place: Name: [ ] Company: [ ] Some question with a long name: [ ] But my list is (somewhat) long and I would like to show them in multiple columns on screens that are wide enough. Ideally, I'd find a POSH method (table-free is semantically appropriate, I think) that works on a reasonable number of browsers. My current page uses a table. I tried CSS with columns: auto; -moz-column-count: auto; -moz-column-width: auto; -webkit-column-count: auto; -webkit-column-width: auto; but Firefox (at least) won't break a table across columns.

  • Most appropriate diagram for GUI button design?

    - by JustADude
    What is the most appropriate diagram for GUI button design? Specifically, I have numerous buttons that will be changing color based on state information from operator input and input from various subcomponents and sensors. I would like to use UML or some other type of design diagrams to be able to capture the color transition. Some folks have suggested sequence diagrams, but I haven't been able to find any good examples that show how to incorporate this design artifact. I would really like to head in this direction to help developers. Thanks a ton for feedback and insights.

  • Thumbnail preview rotator on mouse-over HOW IS THAT CALLED?

    - by Gerben
    I've been searching for hours now but can't get any tutorial on this. I have these thumbnails on my homepage which are the first images of their corresponding posts. What I want is that when I mouse-over a post on the homepage... the corresponding thumbnail should also show/rotate the other images of that particular post... bit like a sneak-peak image rotator... Does anyone know where I can get a tutorial regarding this? How's this called? It seems like I'm searching for the wrong keywords on google as I can't find anything.

  • Ubuntu Screensaver Freezes?

    - by user11833
    I am using ubuntu 10.04. Over the last couple of days, I am having a weird problem: once the machine gets into screen saver, it is impossible to get it "out". I do see the mouse cursor move as I move the mouse, but the login popup (with user / password) does not show up and the screen remains "frozen". Any idea what might be going wrong? For the time being, I have no choice but to restart the computer in order to be able to resume work. Thanks.

  • Do navigation menu links negatively impact SEO for pages' content?

    - by Rodolfo
    I've always had my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?

  • Bukkit send a custom placed name plate?

    - by HcgRandon
    Hello i have been working on a part of my plugin that has waypoints allowing the user to create delete etc. I got to thinking after using and seeing a couple of the disguse plugins. That maybe i could create a command toggle that would show the user where the waypoints they have are! I know how to do all of this i just have no idea how to display a nameplate to the client. I know its possible because disguisecraft does it i tried looking though their code but couldent find much... I belive to get this effect i need to send packets to the client if someone can direct me to a list of bukkit packets or even a solution to sending the client a custom located nameplate that would be fantastic! Thanks in advanced.

  • Hybrid Columnar Compression

    - by user12620172
    You heard me in the past talk about the HCC feature for Oracle databases. Hybrid Columnar Compression is a fantastic, built-in, free feature of Oracle 11Gr2. One used to need an Exadata to make use of it. However, last October, Oracle opened it up and now allows it to work on ANY Oracle DB server running 11Gr2, as long as the storage behind it is a ZFSSA for DNFS, or an Axiom for FC. If you're not sure why this is so cool or what HCC can do for your Oracle database, please check out this presentation. In it, Art will explain HCC, show you what it does, and give you a great idea why it's such a game-changer for those holding lots of historical DB data. Did I mention it's free?
