  • Flex: Can I assign propertiy of multi-layer object to Chart's xField or yField?

    - by Sean Chen
    Hi, I have a question about how to assign property of a multi-layer object to Chart's xField or yField. For example: var obj:Object = new Object(); var store:Object = new Object(); store.store1 = 300; store.store2 = 200; store.store3 = 250; obj.date = "2010/04/26"; obj.count = 2; obj.store = store; Because I have to draw multiple LineSeries, the yField on different series must be assigned to obj.store.store1~store3. How can I set yField in different layer of object?

  • Using a "local" S3 emulation layer as a replacement for HDFS?

    - by user183394
    I have been testing out the most recent Cloudera CDH4 hadoop-conf-pseudo (i.e. MRv2 or YARN) on a notebook, which has 4 cores, 8GB RAM, an Intel X25MG2 SSD, and runs a S3 emulation layer my colleagues and I wrote in C++. The OS is Ubuntu 12.04LTS 64bit. So far so good. Looking at Setting up hadoop to use S3 as a replacement for HDFS, I would like to do it on my notebook. Nevertheless, I can't find where I can change the jets3t.properties for setting the end point to localhost. I downloaded the hadoop-2.0.1-alpha.tar.gz and searched the source without finding out a clue. There is a similar Q on SO Using s3 as fs.default.name or HDFS?, but I want to use our own lightweight and fast S3 emulation layer, instead of AWS S3, for our experiments. I would appreciate a hint as to how I can change the end point to a different hostname. Regards, --Zack

  • How to access Grails domain classes in Java service layer?

    - by batmannavneet
    How can I use grails domain classes (which is in groovy) in service layer which is in Java/Spring. When using the grails MVC, everything is fine as I can use controller to access domain objects and call CRUD and other dynamic methods on them. But, what I am wondering is is there a clean way to do it from Java - say the service layer. For example, I may want to develop a reporting framework where I need to use domain objects to access the DB. I Hope the question is clear. This should be a standard problem that everybody must have faced in a reasonably sized project. I am just wondering how it is solved..maybe I am missing something here. thanks.

  • How to capture a click on a link on a temporary layer that is hidden when the focus changes

    - by hstoerr
    We have a layer that appears when a certain text input has the focus and that should dissappear when the input loses the focus. I tried to do it like this: <input type="text" onblur="document.getElementById('hideme').style.display='none'" /> <div id="hideme">Textextext <a href="http://disney.com/">disney</a> text</div> My problem is: when the user clicks on the link link, the browser does not follow this link. It seems the layer disappears before the browser checks where the click goes. What can I do here? One idea would be to watch whether the mouse enters the hideme div and not to close it when the mouse cursor is in there, but this seems way to complicated. Do you have a better idea? By the way: you can try it out very easy by pasting this into the Tryit Editor of w3schools. :-)

  • How to Add a Dynamic Layer to an Esri Map Control Programatically in WPF?

    - by Scott
    Just as the question asks. I have an Esri map control and want to add a Rastor image to the control in WPF and don't know how to do it. I see that I can add layers to the Map control, but is there a way to add a Raster image to a map control? I did find this code to turn the raster image into a Dynamic layer, but Im still lost on how to add a dynamic layer to the control it self. http://resources.esri.com/arcgisserver/apis/silverlight/index.cfm?fa=codeGalleryDetails&scriptID=16723 Thank you!

  • Improving the performance of an nHibernate Data Access Layer.

    - by Amitabh
    I am working on improving the performance of DataAccess Layer of an existing Asp.Net Web Application. The scenerios are. Its a web based application in Asp.Net. DataAccess layer is built using NHibernate 1.2 and exposed as WCF Service. The Entity class is marked with DataContract. Lazy loading is not used and because of the eager-fetching of the relations there is huge no of database objects are loaded in the memory. No of hits to the database is also high. For example I profiled the application using NHProfiler and there were about 50+ sql calls to load one of the Entity object using the primary key. I also can not change code much as its an existing live application with no NUnit test cases at all. Please can I get some suggestions here?

  • Should i use partial classes as business layer when using entity framework?

    - by samsur
    I am working on a project using entity framework. Is it okay to use partial classes of the EF generated classes as the business layer. I am begining to think that this is how EF is intended to be used. I have attempted to use a DTO pattern and soon realized that i am just creating a bunch of mapping classes that is duplicating my effort and also a cause for more maintenance work and an additional layer. I want to use self-tracking-entities and pass the EF entities to all the layers. Please share your thoughts and ideas. Thanks

  • Replace dual-XP installs with single-XP install and repartition drive?

    - by caeious
    Hello, The Current Situation I have a hard drive that currently is split up like so: Primary Partition C: 9.77 GB NTFS Healthy (System) with XP Pro (in Polish) installed Extended Partition D: 39.82 GB NTFS Healthy (Boot) with XP Pro (in English) installed 6.30 GB Free space When I start my comuter I get a black and white Windows Boot Manager dual boot screen with 2 choices both being Microsoft Windows XP. The first choice is the English version of XP and the second choice is the Polish version of XP. Images of my Computer Management window and Dual Boot screen The Mission What I need to do is get rid of the entire extended partition (D: 39.82 GB & 6.30 free space) and just have the one primary C: drive which I assume will be somewheres around 55 GB big. So in the end I just want XP Pro in English running on my C: drive and no black and white boot screen to show up when starting up my laptop. The Question How do I go about successfully completing The Mission with out making my computer a useless pile of silicon, plastic and metal? UPDATE: So I went ahead and tried to follow Neal's suggestion but hit a wall. I got to a Windows XP Pro install screen that had the 3 following options as well as my drive data: To set up Windows XP on the selected item, press Enter To create a partition in the unpartitioned space, press C To delete the selected partition, press D 57232 MB Disk 0 at Id 0 on bus 0 on atapi [MBR] C: Partition1 [NTFS] 10001 MB ( 4642 MB free ) Unpartitioned space 6448 MB D: Partition2 [NTFS] 40774 MB ( 26225 MB free ) Unpartitioned space 8 MB I figured I would go with the first choice ((To set up Windows XP on the selected item, press Enter)) because I just wanted to set up Windows XP on C: Partition1 (which was preselected) so I pressed Enter which brought me to a screen displaying this message: You chose to install Windows XP on a partition that contains another operating system. Installing Windows XP on this partition might cause the other operating system to function improperly. CAUTION: Installing multiple operating systems on a single partition is not recommended. So this leads me to 2 new questions: How do I get rid of the Windows XP (Polish language) install on C: Partition 1 so that I can cleanly and safely install Windows XP (English language) on it? Neal, is this what you meant by me possibly having to delete the partition that the Windows XP (Polish language) install was located on? Since I have the option to delete partitions with the 3rd choice ((To delete the selected partition, press D)), should I do that on this screen or wait until I have Windows XP (English language) safely installed on C: Partition 1? I have to ask these questions because I have read that it is possibly dangerous to delete hard drive partitions. Just being cautious.

  • Sync sticky notes between Windows 7 and Linux on Dual Boot System?

    - by TheLQ
    I love Windows 7's sticky notes, it really helps. Here's the issue though: I dual boot Windows 7 and Fedora Linux. Whichever OS I'm in is random, depending on what I'm wanting to do at the time. Therefore I can't rely on just keeping the notes in my "primary" OS and referencing it when needed Does anybody know of a way to sync Windows 7's Sticky Notes with Fedora? Various Google searches haven't yielded much as they deal with primarily syncing between common OS's.

  • How to set my Bamboo Fun to work only on ONE of my dual screens?

    - by Przemyslaw Piekarski
    I need dual screen for my web developer job but when I do illustrations I prefer to work on a single screen to avoid the stretching of the workspace which affects tablet's precision. Is there a way to make my tablet work only on my primary screen and, at the same time, use mouse for both screens? I've looked into my tablet's preferences and haven't found it. I use Windows XP, Bamboo Fun A5, ATI Radeon X 1050. Thanks in advance.

    - by nicon

  • How do I get the same dual-screen experience on my install as I had on the 12.04 Live CD?

    - by Alexander G
    I downloaded, burned to disc, and booted Ubuntu 12.04 Precise (I defected to Arch for a year when I got fed up of Natty). I was pleasantly surprised by both of my monitors working perfectly on there (needed to rearrange as my secondary monitor is to the left, however). So I installed. There's no recognition of the second monitor now, and it doesn't appear in the settings. I've also enabled the Nvidia driver. What do I do?

  • How to solve this problem starting new Opera-windows on dual monitor-setup?

    - by Mnementh
    I use Opera and have a setup with two monitors. If I want to open a new URL opera -newwindow URL. The outcome differs, if I execute this command in a program on the same screen where Opera is, or on the other. On the same screen everything is fine. I get the message opera: Activated running instance and the new window with the URL is opened. On the other screen, I get a dialog with the following message: It appears another opera instance is using the same configuration directory because its lock file is active: /home/(my name)/.opera/lock and the URL is not shown. That's not only from console, also if I click a link in E-Mail or so. How can I fix this? Window-manager is awesome, if it does make a difference.

  • How to solve dual monitor issue, which happens only during X start?

    - by tamashumi
    When is loading and two monitors are connected, instead of a login screen I see this: ...after clicking OK, selection appears: Then I'm following to console login, disconnecting by hand the secondary monitor cable, restart lightdm with a command sudo service lightdm restart ...and voila! System loads fine. If I disconnect the cable before boot X will be loaded fine too. It's not a nice 'feature' when I have to disconnect the cable each boot or X restart. I was trying to delete monitors.xml but it didn't help. The situation relates to my notebook with Intel integrated GPU. The same happens on two different pairs of monitors: at the office and at home. How can I fix this? Ubuntu 12.04 x64 Desktop with default Unity GUI.

  • How do I get movies to work in my dual CD/DVD computer?

    - by user289178
    I have an older Dell Optiplex GX620. It has an IDE CD drive and an IDE DVD drive. I cannot seem to get Ubuntu 14.04 to allow movies to play. I've tried installing libdvdcss2 as well as the libdvdread4. VLC was installed last, but each time I attempt to play a movie, the player flashed briefly, then goes back to the initial screen like I didn't even have a DVD in the drive. I'm fairly new to the linux world, so any/all suggestions would be helpful.

  • How do you dual boot Windows 7/8 seperatly with GRUB?

    - by Aaron
    I installed the beta version of Windows 8 and re-installed GRUB. When I boot my computer and select Windows 7, I get the new Windows 8 booting screen asking to boot between either Windows 7 or 8. If I choose Windows 7, my computer then restarts and I have to select Windows 7 again in order to boot into 7. But if I choose Windows 8 it boots right up. I understand I can choose which OS to boot by default, but I want my GRUB options to be the only way to choose between OS's. So my question is, how can I set this up so that when I click on Windows 7, I go there, and when I select Windows 8, I boot 8?

  • Dual monitor ATI hd 4350 (1GB PCI-e), ubuntu 12.04 (pear Linux) Do I need the ATI driver or open source?

    - by Geeve
    I think I covered it in the title, Right now both monitors are mirrored (both 19" at 1440x900). I guess what I need to know is do I need the ATI proprietary driver or will the open source driver from Ubuntu (additional drivers) work? I want to expand the desktop between the two monitors. Still finishing install and running updates now, I just wanted to gather all documentation and downloads prior to doing what is necessary. Thanks Geeve
