• Modify javascript to display a SharePoint list from another site collection, want items to open in a modal dialog [on hold]

  - by FRD

  I'm trying to modify the javascript below so that when a list from one site collection is displayed in another site collection and an item is selected, it opens in a dialog box instead of taking over the entire page and forcing the user to the originating site. <div id="ExternalListContainer"></div> <script type="text/javascript"> //wait for SP to load up ExecuteOrDelayUntilScriptLoaded( function LoadExternalList() { //turn on xsite scripting support for jquery $.support.cors = true; //load the external SP list $("#ExternalListContainer").load("http://originatingsiteurl.aspx table.ms-listviewtable", function(response, status, xhr) { //find all the list items and convert to HTML so we don't see the code $("#ExternalListContainer").find(".ms-vb2").each(function () { $(this).html($(this).text()); }); }); }, "sp.ribbon.js"); </script>

• Changing CSS classes when different strings are displayed in a text element with jQuery

  - by Nick Maddren

  I'm just wondering if this method would be possible using jQuery HTML and PHP. Basically I have a filtering system were products are listed, some have different attribute values such as Hatchback for example. The text element that holds these PHP echo's also have a css class that implements an icon. I'm just wondering can I alter class's that are added to a html element just by looking at the string? So for example if the string displays "Pick-up" then jQuery alters the class and adds the one associated with the "Pick-up" string? Thanks sorry if this is a little confusing, I can explain more if needed.

• Am I violating LSP if the condition can be checked?

  - by William

  This base class for some shapes I have in my game looks like this. Some of the shapes can be resized, some of them can not. private Shape shape; public virtual void SetSizeOfShape(int x, int y) { if (CanResize()){ shape.Width = x; shape.Height = y; } else { throw new Exception("You cannot resize this shape"); } } public virtual bool CanResize() { return true; } In a sub class of a shape that I don't ever want to resize I am overriding the CanResize() method so a piece of client code can check before calling the SetSizeOfShape() method. public override bool CanResize() { return false; } Here's how it might look in my client code: public void DoSomething(Shape s) { if(s.CanResize()){ s.SetSizeOfShape(50, 70); } } Is this violating LSP?

• Interface design where functions need to be called in a specific sequence

  - by Vorac

  The task is to configure a piece of hardware within the device, according to some input specification. This should be achieved as follows: 1) Collect the configuration information. This can happen at different times and places. For example, module A and module B can both request (at different times) some resources from my module. Those 'resources' are actually what the configuration is. 2) After it is clear that no more requests are going to be realized, a startup command, giving a summary of the requested resources, needs to be sent to the hardware. 3) Only after that, can (and must) detailed configuration of said resources be done. 4) Also, only after 2), can (and must) routing of selected resources to the declared callers be done. A common cause for bugs, even for me, who wrote the thing, is mistaking this order. What naming conventions, designs or mechanisms can I employ to make the interface usable by someone who sees the code for the first time?

• Is client side JavaScript capable of replicating the Node.JS module loading system?

  - by jt0dd

  I like the Node.JS style of JavaScript, where I can write all of my functionalities into smaller files and then require those neatly from within my code. I'm even thinking about trying to write a framework to mimic that behavior in client-side JS. My goal would be to implement the module loading system as accurately as possible - See Module docs. For require(), I can use things detailed in answers to this question, most notably JQuery's $.getScript(). It seems to me that other aspects of the module loading system should be possible as well. So I'm asking more experienced programmers here first, before I waist my time: Is there something that I'm missing that's going to cause such an attempt to fail miserably, or can this be successfully done?

• Confused about javascript module pattern implementation

  - by Damon

  I have a class written on a project I'm working on that I've been told is using the module pattern, but it's doing things a little differently than the examples I've seen. It basically takes this form: (function ($, document, window, undefined) { var module = { foo : bar, aMethod : function (arg) { className.bMethod(arg); }, bMethod : function (arg) { console.log('spoons'); } }; window.ajaxTable = ajaxTable; })(jQuery, document, window); I get what's going on here. But I'm not sure how this relates to most of the definitions I've seen of the module (or revealing?) module pattern. like this one from briancray var module = (function () { // private variables and functions var foo = 'bar'; // constructor var module = function () { }; // prototype module.prototype = { constructor: module, something: function () { } }; // return module return module; })(); var my_module = new module(); Is the first example basically like the second except everything is in the constructor? I'm just wrapping my head around patterns and the little things at the beginnings and endings always make me not sure what I should be doing.

• An algorithm for finding subset matching criteria?

  - by Macin

  I recently came up with a problem which I would like to share some thoughts about with someone on this forum. This relates to finding a subset. In reality it is more complicated, but I tried to present it here using some simpler concepts. To make things easier, I created this conceptual DB model: Let's assume this is a DB for storing recipes. Recipe can have many instructions steps and many ingredients. Ingredients are stored in a cupboard and we know how much of each ingredient we have. Now, when we create a recipe, we have to define how much of each ingredient we need. When we want to use a recipe, we would just check if required amount is less than available amount for each product and then decide if we can cook a dinner - if amount required for at least one ingredient is less than available amount - recipe cannot be cooked. Simple sql query to get the result. This is straightforward, but I'm wondering, how should I work when the problem is stated the other way round, i.e. how to find recipies which can be cooked only from ingredients that are available? I hope my explanation is clear, but if you need any more clarification, please ask.

• Started wrong with a project. Should I start over?

  - by solidsnake

  I'm a beginner web developer (one year of experience). A couple of weeks after graduating, I got offered a job to build a web application for a company whose owner is not much of a tech guy. He recruited me to avoid theft of his idea, the high cost of development charged by a service company, and to have someone young he can trust onboard to maintain the project for the long run (I came to these conclusions by myself long after being hired). Cocky as I was back then, with a diploma in computer science, I accepted the offer thinking I can build anything. I was calling the shots. After some research I settled on PHP, and started with plain PHP, no objects, just ugly procedural code. Two months later, everything was getting messy, and it was hard to make any progress. The web application is huge. So I decided to check out an MVC framework that would make my life easier. That's where I stumbled upon the cool kid in the PHP community: Laravel. I loved it, it was easy to learn, and I started coding right away. My code looked cleaner, more organized. It looked very good. But again the web application was huge. The company was pressuring me to deliver the first version, which they wanted to deploy, obviously, and start seeking customers. Because Laravel was fun to work with, it made me remember why I chose this industry in the first place - something I forgot while stuck in the shitty education system. So I started working on small projects at night, reading about methodologies and best practice. I revisited OOP, moved on to object-oriented design and analysis, and read Uncle Bob's book Clean Code. This helped me realize that I really knew nothing. I did not know how to build software THE RIGHT WAY. But at this point it was too late, and now I'm almost done. My code is not clean at all, just spaghetti code, a real pain to fix a bug, all the logic is in the controllers, and there is little object oriented design. I'm having this persistent thought that I have to rewrite the whole project. However, I can't do it... They keep asking when is it going to be all done. I can not imagine this code deployed on a server. Plus I still know nothing about code efficiency and the web application's performance. On one hand, the company is waiting for the product and can not wait anymore. On the other hand I can't see myself going any further with the actual code. I could finish up, wrap it up and deploy, but god only knows what might happen when people start using it. What do you think I should do?

• Best way to load application settings

  - by enzom83

  A simple way to keep the settings of a Java application is represented by a text file with ".properties" extension containing the identifier of each setting associated with a specific value (this value may be a number, string, date, etc..). C# uses a similar approach, but the text file must be named "App.config". In both cases, in source code you must initialize a specific class for reading settings: this class has a method that returns the value (as string) associated with the specified setting identifier. // Java example Properties config = new Properties(); config.load(...); String valueStr = config.getProperty("listening-port"); // ... // C# example NameValueCollection setting = ConfigurationManager.AppSettings; string valueStr = setting["listening-port"]; // ... In both cases we should parse strings loaded from the configuration file and assign the ??converted values to the related typed objects (parsing errors could occur during this phase). After the parsing step, we must check that the setting values ??belong to a specific domain of validity: for example, the maximum size of a queue should be a positive value, some values ??may be related (example: min < max), and so on. Suppose that the application should load the settings as soon as it starts: in other words, the first operation performed by the application is to load the settings. Any invalid values for the settings ??must be replaced automatically with default values??: if this happens to a group of related settings, those settings are all set with default values. The easiest way to perform these operations is to create a method that first parses all the settings, then checks the loaded values ??and finally sets any default values??. However maintenance is difficult if you use this approach: as the number of settings increases while developing the application, it becomes increasingly difficult to update the code. In order to solve this problem, I had thought of using the Template Method pattern, as follows. public abstract class Setting { protected abstract bool TryParseValues(); protected abstract bool CheckValues(); public abstract void SetDefaultValues(); /// <summary> /// Template Method /// </summary> public bool TrySetValuesOrDefault() { if (!TryParseValues() || !CheckValues()) { // parsing error or domain error SetDefaultValues(); return false; } return true; } } public class RangeSetting : Setting { private string minStr, maxStr; private byte min, max; public RangeSetting(string minStr, maxStr) { this.minStr = minStr; this.maxStr = maxStr; } protected override bool TryParseValues() { return (byte.TryParse(minStr, out min) && byte.TryParse(maxStr, out max)); } protected override bool CheckValues() { return (0 < min && min < max); } public override void SetDefaultValues() { min = 5; max = 10; } } The problem is that in this way we need to create a new class for each setting, even for a single value. Are there other solutions to this kind of problem? In summary: Easy maintenance: for example, the addition of one or more parameters. Extensibility: a first version of the application could read a single configuration file, but later versions may give the possibility of a multi-user setup (admin sets up a basic configuration, users can set only certain settings, etc..). Object oriented design.

• using ubuntu command line to replace text in huge file

  - by user299331

  hi i have a huge xml file that i must work with. right now the file is only 1 line that contains about 2 million characters which represent 30,000 records. there are no carriage returns or linefeeds whatsoever. what i need to do is make each record on its own line. new records begin with "" and end with "". i've been looking around here and it seems the tools to use are: sed, tr or awk but i'm not sure which is most appropriate. i've tried this to no avail: tr '<ROW' '\012 <ROW' <source.xml |tee destination.xml above seems to output some pretty weird stuff so i must be way off here. maybe its that "<" character that is the problem?

• Run a VirtualBox VM in a second X-Server with Graphic support

  - by Scindix

  I'm starting a VirtualBox VM (Windows 7) in a second X-Server (Ubuntu 14.04) and i'm using the following xinit script (/path/.vboximage): optirun VBoxManage startvm <vm name> & exec tinywm I recognized that while running Virtualbox normally under Gnome (Unity to be precise ;-) ) I get full graphics support. But when I run it on a second xserver there seem to be some problems. E.g. Windows Aero doesn't seem to work and Chrome WebGL demos are running with poorer performance. I'm not a big Windows expert, so I don't know how I could check the used Graphic card (specification). But it is very obvious that something has changed when running the vm in the extra X-Server. Also when I try to replace tinywm with compiz I get the unity frame around the VM, which also seems to have no graphics acceleration (no transparency effects) So it seems that the X-Server doesn't have Graphic acceleration at all. I have a NVidia 525m and an Intel HD3000 which are both capable of advanced graphics. I'm starting the above script with startx /path/.vboximage - :1 How could I fix that?

• How to boot Chromebook from SD card without entering developer mode?

  - by Caleb Strutz

  I have a question. Is it at all possible to install Ubuntu or Chrubuntu onto a SD Card and then boot a chromebook from said SD card? I know this is easily possible, but the chromebook in question belongs to my school, so I cannot enter developer mode, because that would void the license agreement. I don't really care how technical or how many steps this will take, as long as it can be possible. Thanks in advance.

• window borders, menu bar missing over VNC

  - by zacaj

  I'm running Ubuntu 14.04 with Unity and Gnome3, however I don't have a screen hooked up anymore. I have installed x11vnc and run it with "-create" so that it will create a new X11 session, however when I VNC to it, the menu bar, window borders, etc are missing, windows are ordered based on creation time, and cannot be resized. Now, I don't really care if I end up with Ubuntu or Gnome's window manager, as long as this doesn't mess up my normal desktop stuff if I should happen to hook a monitor up again, and I'm not even attached to x11vnc if someone can point me to a good complete tutorial using something else, but I've been trying vino and tightvnc and rdp and x11vnc is the only one I've managed to get this far.

• How can I undo this key mapping?

  - by user273872

  First of all sorry my punctuation will be bad. its hard to type when keys are not doing what you expect. Eg it keeps scaring the **** out of me by taking a screen shot when I push the up arrow lolol So anyways, I broke a key on my keyboard and used xkeycaps to remap it to an unused key which worked. But then I realized it screwed up other keys... I think this is the program I used http://www.jwz.org/xkeycaps/man.html And then after doing the modifications I found out how to save them from the second answer in this question How to Map my enter key to a different key down where it says this "When you are happy with your current keymap and want to use it in future X-sessions, run the following command to save it: xmodmap -pke ~/.Xmodmap"

• Still can't mount windows 8 drive after restart

  - by Ishai Bloch

  After following the instructions in other posts, I am still getting the same error when I try to mount my Windows 8 drive in Ubuntu 14.04 on a dual boot system. I have disabled fast start after shutdown, hybrid hibernation, and the preinstalled Asus Instant On service. I have tried restarting Windows rather than shutting down. In all cases I get the same error message, namely: Error mounting /dev/sda4 at /media/jesse/OS: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda4" "/media/jesse/OS"' exited with non-zero exit status 14: Windows is hibernated, refused to mount. Failed to mount '/dev/sda4': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option. I did not have the same issue before upgrading from Ubuntu 12 to 14. For what it's worth my computer is supposedly a "hybrid" with an SSD drive installed, although I can't see that the SSD drive is being used at all with my present settings. Any thoughts?

• How to solve package issues/dependencies

  - by Wolfgang Kuehne

  Background info I am trying to install Veins simulation environment by following the tutorial provided by the author. In step 1 it is required to install some packages in Linux, the tutorial suggest this commands to be executed on Terminal: sudo apt-get install build-essential gcc g++ bison flex perl tcl-dev tk-dev blt libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-1.0-0 openmpi-bin libopenmpi-dev libpcap-dev autoconf automake libtool libxerces-c2-dev proj libgdal1-dev libfox-1.6-dev When I execute this command, I immediately get: E: Package 'proj' has no installation candidate Then I remove the proj from the command and execute it again without proj in it, next I get: The following packages have unmet dependencies: libgdal1-dev : Depends: libgdal-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. So, I remove libgdal1-dev from the command as well. And it executes file, by downloading the remaining packages. To troubleshoot the problem with proj and libdgal1-dev I go to the Synaptic Package Manager. libgdal1-dev I search for libgdal1-dev in Synaptic Package Manager and I get an entry. I Mark for Installation and then Synaptic Package Manager suggests removing libxerces-c2-dev which is actually added via the initial command. Should I trust Synaptic Package Manager with this suggestion, and proceed further? proj What should I do about proj. There are some packages in Synaptic Package Manager such as proj-bin or libproj-dev. Should I install them? I think proj has to do with this and this What should I do to make sure that this simulation tool works fine?

  Can anyone make something out of this? After getting the invitation for upgrading from 12.04 to 14.04, I click on the 'Yes, Upgrade Now' button and I get a little window saying 'Authentication failed', Authenticating the upgrade failed. There may be a problem with the network or with the server. It's weird since I have a good solid connection while doing this. Thanks and any help would be great. Thanks again!

• usb drive filesystem?

  - by purbleguy

  So, school is approaching quickly, and one of the things on my supply list is a usb drive. Now I'm asking myself what filesystem to use. After some research, I found ext4 to be the most stable drive filesystem. But, I also found that Windows (The OS used by every computer in my school) can't read ext4 formatted drives without special drivers, and I'm sure the school wouldn't be too happy with me having to install the windows ext4 drivers on every computer I use with my usb. So, my question is, Should I use fat32, one of the ext filesystems (2, 3 or 4 would work) or NTFS, I have an ubuntu laptop, a Mac desktop, and of course the school computers I use are Windows, so which would be the best filesystem for my usb.

• Reset Windows share password after 'Remember forever'

  - by timmit

  I've been happily connecting to a Windows share from my 14.04 machine. When I first entered the password for the share I chose to have it remembered forever. Yesterday I changed the password on the Windows machine, today I can't access the share... My searches for a solution have been in vain, most suggestions say that there is an entry in the Password & Keys (seahorse) app that should be deleted, this doesn't exist for me. I even ran seahorse as the root user to see if the key was hidden away in there, but no luck. Is there anywhere else I should be looking? Shouldn't the Nautilus app be prompting me to update my password in this scenario?

• Need to know best way to utilize LVM to backup Ubuntu

  - by William Leininger

  So I've had issues with Windows which forced me to install and learn Ubuntu as I'm fed up with MSFT. So now I need to know the most efficient/best way to image Ubuntu so that if I messed something up in one point in time I could always come back to the healthy point in time. During the install I saw an option for LVM and read what it is though I don't know how to utilize it to prevent a situation where I have to reinstall everything. Help? Note: I found on the right hand side of this Ask A Question area an area titled Similar Questions giving me Setting up LVM Snapshot as a backup/restore point in ubuntu This is pretty in depth and a bit complex, though completely doable, is it possible to just use LVM out of the box after a complete HDD wipe and normal Ubuntu install? :Fingers crossed and rabbits foot in hand:

• Problem after upgrading to 14.04: Unable to mount - Not authorized

  - by Elisa Velasco Lorenzo

  This is the first time I ever post on this forum. I have used Ubuntu for 7 years, and every time I've had a problem, I have browsed the web and I have been able to solve it thanks to the help given on forums to other users experiencing the same issues (I do not have technical knowledge on Ubuntu). This time, I've spent hours reading forums and typing commands and nothing helps. I am exhausted. Upgrading to 14.04 has proved itself a mistake. Many things won't work anymore. But the one which worries me right now is external media not automounting anymore. I know other people have had the same issue and I have carefully read their threads, but nothing helps!!
