  • jQuery "Autcomplete" plugin is messing up the order of my data

    - by Max Williams
    I'm using Jorn Zaefferer's Autocomplete plugin on a couple of different pages. In both instances, the order of displayed strings is a little bit messed up. Example 1: array of strings: basically they are in alphabetical order except for General Knowledge which has been pushed to the top: General Knowledge,Art and Design,Business Studies,Citizenship,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Displayed strings: General Knowledge,Geography,Art and Design,Business Studies,Citizenship,Design and Technology,English,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Note that Geography has been pushed to be the second item, after General Knowledge. The rest are all fine. Example 2: array of strings: as above but with Cross-curricular instead of General Knowledge. Cross-curricular,Art and Design,Business Studies,Citizenship,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Displayed strings: Cross-curricular,Citizenship,Art and Design,Business Studies,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Here, Citizenship has been pushed to the number 2 position. I've experimented a little, and it seems like there's a bug saying "put things that start with the same letter as the first item after the first item and leave the rest alone". Kind of mystifying. I've tried a bit of debugging by triggering alerts inside the autocomplete plugin code but everywhere i can see, it's using the correct order. it seems to be just when its rendered out that it goes wrong. Any ideas anyone? max

  • Silverlight and WCF Ria Services

  • 2-column table with two foreign keys. Performance/design question.

    - by Emanuel
    Hello everyone! I recently ran into a quite complex problem and after looking around a lot I couldn't find a solution to it. I've found answers to my questions many times before on stackoverflow.com, so I decided to post here. So I'm making a user/group managment system for a web-based project, and I'm storing all related data into a postgreSQL database. This system relies on three tables: USERS GROUPS GROUP_USERS The two first tables simply define all the users and all the groups on the site, and the last table, GROUP_USERS, stores the groups every user is part of. It only has two columns: USER_ID GROUP_ID Since every user can be a member of several groups, I decided to make a separate table for this purpose, rather than storing a comma separated column in the USERS-table. Now, both columns are foreign keys, and I want to make them both primary keys as well, this since each combination of USER_ID and GROUP_ID has to be unique, and if I give them the constraint UNIQUE pgAdmin tells me that each table should have at least one Primary key. But now I am stuck with what seems to be a lot of indexes and relations to a very small table only containing numbers. In the end, I want this table to be as fast as possible, even if containing tens of thousands of rows. Size on disk shouldn't be a problem since its just all numbers anyway, but it feels quite stupid to have a full-sized index refering to a smaller table. Should I stick with my current solution, store comma-separated values in a column in the USERS-table or is there any other solution I should be aware of. PS. I don't want to use an array-column, even if they are supported by postgreSQL. I want to be as generic as possible so I can switch database later on, if necessary. EDIT: I other words, will using a compound primary key and two foreign keys in one table with only two columns have a negative impact on performance rather than the opposite due to the size of the generated index? Thank you!

  • Multi level menu, active links css highlight. (Ruby on Rails)

    - by klamath
    Site structure: / /products /products/design /products/photo /about I want to see parent menu item also highlighted by CSS, when child is active. (When 'design' or 'photo' is active 'products' should be highlighted too.) I'm using this for child and simple urls: <li class="<%= current_page?(:action => 'design') %>"> <%= link_to_unless_current 'Design', :design %> </li> For 'products' checking should be like: <%= current_page?(:action => 'products') || current_page?(:action => 'design') %> || current_page?(:action => 'photo') %> But triple || is not right, and it's become complicated. I saw a helper, like this one: def current(childs) if current_page?(:action => childs) @container = "active" else @container = "inactive" end end Which is used by: <%= current(:photo) %> So, how to put all my 3 checks for 'products', 'design', 'photo' in one helper? And make possible to use something like <%= current(:products, :design, :photo) %>

  • CentOS RPM database trashed, "rpm --rebuilddb" won't fix, can I recover using /var/lib/rpm/ from a 2

    - by user18330
    My RPM database is shot, neither rpm or yum works. Supposedly "rpm --rebuilddb" will fix it, but it doesn't in my case. This server has three sister servers that are basically identical, and have working RPM databases. I tried copying /var/lib/rpm/ from working server to the sick one, but that didn't fix it. Any ideas of how I can use good server's rpm to fix the sick one?

  • Know any unobstrusive, simple GUI guidelines or design recommendations for notifications?

    - by Vinko Vrsalovic
    Hello again. I'm in the process of designing and testing various ideas for an application whose main functionality will be to notify users of occurring events and offer them with a choice of actions for each. The standard choice would be to create a queue of events showing a popup in the taskbar with the events and actions, but I want this tool to be the less intrusive and disrupting as possible. What I'm after is a good book or papers on studies of how to maximize user productivity in these intrinsically disruptive scenarios (in other words, how to achieve the perfect degree of annoying-ness, not too much, not too little). The user is supposedly interested in these events, they subscribe to them and can choose the actions to perform on each. I prefer books and papers, but the usual StackOverflow wisdom is appreciated as well. I'm after things like: Don't use popups, use instead X Show popups at most 3 seconds Show them in the left corner Use color X because it improves readability and disrupts less That is, cognitive aspects of GUI design that would help users in such a scenario.

  • Ofice for Mac 2011 does not start, how do I repair the database?

    - by RomanT
    After a TimeMachine restore; Office 2011 is having kittens over permissions it would seem. Having attempted a 'repair' out of Disk Utility, am still seeing: there is a problem with the Office database upon startup, after which Word/Excel work without issues. Outlook on the other hand won't even start. Given the obvious message here "You do not have write access to the Outlook application folder" – where is the DB located to check?

  • Is there any project estimation tool to give estimate for web design/ development work?

    - by jitendra
    Is there any project estimation tool which gives estimates for web design/ development work? I don't have to calculate Price just want to calculate estimated time. Just for example, for things like: Page creation (layout in XHTML) CSS creation Content creation (Word to HTML, including images in some pages) Bulk PDF upload PHP Script for Form Testing all pages I need like Items Quantity Time for each task(min) Estimated total (in hour) PDF upload x 30 = 2 min = 60 Min pages with images x 30 = 15 min for each = 60 Min Is there any simple JQuery calculator power with JQuery? Where we can add add/remove custom thing to calculate time? Or any other free online/offline tool ?

  • OOP Design Question - Where/When do you Validate properties?

    - by JW
    I have read a few books on OOP DDD/PoEAA/Gang of Four and none of them seem to cover the topic of validation - it seems to be always assumed that data is valid. I gather from the answers to this post (http://stackoverflow.com/questions/1651964/oop-design-question-validating-properties) that a client should only attempt to set a valid property value on a domain object. This person has asked a similar question that remains unanswered: http://bytes.com/topic/php/answers/789086-php-oop-setters-getters-data-validation#post3136182 So how do you ensure it is valid? Do you have a 'validator method' alongside every getter and setter? isValidName() setName() getName() I seem to be missing some key basic knowledge about OOP data validation - can you point me to a book that covers this topic in detail? - ie. covering different types of validation / invariants/ handling feedback / to use Exceptions or not etc

  • What's a good design to handle multiple global hotkeys?

    - by Alex
    I'm struggling to think of a good design to handle multiple global hotkeys. Say I have three different functions bound to three different global hotkeys... Play Song | Ctrl + P Skip Song | Ctrl + N Increase Volume | Ctrl + V What's a good, effective way to check if the hotkey pressed conforms to a certain function? I'm using a class very similar to this: http://www.liensberger.it/web/blog/?p=207 Should I create a new instance of the hotkey class for each hotkey? Hotkey hotkey = new Hotkey(); hotkey.RegisterHotkey(Shortcut.ModifierKeys.Control, Keys.F10); hotkey.KeyPressed += ((s, args) => { //Do Something! }); Or should I have an enum with different hotkey functions and manage it from within the hotkey class to prevent multiple instances (seems wasteful but easy). Thanks for any advice / help in advance.

  • Do you know of a free .Net component for visual flow model graph design and editing?

    - by Ivan
    An app (C#4, WinForms, Entity Framework, SQL Server 2008) of mine maintains a graph of interconnected objects, each having some simple member fields and a set of many directed (in and out) one-to-one links to other objects. I'd like to offer a user an ability to view and edit this graph visually some way, creating and removing connections, modifying objects attributes values and introducing/dropping objects. I suppose there has to be a framework (at list a primitive kind of) for this as visual model design tools are pretty common to meet. Do you know one?

  • What is the best tool to achieve this API design?

    - by Jose Fernandez
    Our web app offers a service that allows a "Publisher" to create a website (we give them a CMS system) that is ready to provide this service to "Members" (think Shopify). We have some possible clients that wish to become "Publishers" but they already have existing websites (vbulletin, word press blog, etc) with their own user base. We wish to develop an API that would allow these "Publishers" to keep using their own websites, and embed our services into them. Our main business requirement is that once "Members" are logged into the "Publishers" existing system, they should be able to also access our website without having to log-in again OR have to create another account there. The process should be seamless to the "Member" and "Publishers" should not have to sync their user base with our system. We also want to use an existing API authentication/authorization system instead of creating our own (OAuth, OpenID, etc) What would be the best way to use OAuth to achieve this sigle-sign on design? If OAuth is not the best tool, is there any other one out there that fits our requirements?

  • iPhone interface design considerations: checkbox and drop-down menu ?

    - by Jesse Armand
    This may not be a programming question, but I don't know where to ask for this and it's still related. We all know that the checkbox and drop-down menu is a UI paradigm brought in from HTML or web interface. I'm not asking for code implementations here. A google search had produced many results. Although if anyone is willing to share that's great. So the question is: Is this a good design approach if we just want to provide a checkbox or drop-down functionality? (e.g. for quizzes, or forms)

  • How do I design a .NET (C#) for a program that needs to run as a Windows service but also have a web

    - by hjoelr
    I am designing a piece of software that needs to operate different pieces of hardware based mainly on a schedule but it also needs to have a web interface for configuring settings, configuring the schedule, and possibly even manually controlling the hardware. I'm not sure how to design the architecture of software like this. One thought that I have had was to create a Windows service that does the communication with the hardware as well as "publishing" web services through WCF and then having an ASP.NET application that then controls the Windows service through WCF. This approach seems to be a lot of work for what I'm trying to accomplish. Could someone please give me some direction whether or not this is a good approach, and even give me a better way to do it if one exists? Thanks! Joel

  • Big table or multiple separate tables? (database design question)

    - by Khou
    This is a database design question. I want to build an invoice web application, an invoice can have many items, and each user can have an inventory list of product items that they can store and choose to add to an invoice item. My questions are: 1. Should I store all product inventory for all users using my application under one single table? Or have a separate product inventory table created for each user? 2. Is this even possible? 1 table is easier, but what if this single table grows too big, will I have a problem? (primary key INT).

  • How do I design a web service (microsoft) that can be consumed by multiple end points?

    - by Ben McCormack
    My company is planning to implement a solution in multiple applications that will help to validate mailing addresses at the point of data entry. We're using UPS's Extended Address Validation (XAV) web service API to validate the addresses. Our current plan is to build a .NET web service that can be used to communicate between our applications and the UPS API. We have applications in VB6, classic ASP, and .NET 2.0, so we'd like to implement a solution that can be easily consumed by each of these programming environments. What are our (Microsoft) options for designing a web service that can be consumed by multiple clients? In particular, is there a way to design a single web service that can respond with JSON (in case we want to validate our web page using javascript) in addition to XML? I'm new to designing web services and want to make sure we consider all of our options. I've heard terms like asmx, WCF, OData, etc., but I don't know which frameworks will support what we're trying to do and where to start.

  • Does XAML design mode support more color than code view?

    - by Rahul Soni
    While working with SilverLight using Visual Studio 10, I found that in design mode XAML allows a wide plethora of colors. For ex. Lime is a valid color in XAML. <LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5"> <GradientStop Color="Yellow" Offset="0" /> <GradientStop Color="Lime" Offset="1" /> While working with code though, I found that Lime and many other colors are missing... GradientStop blueGS = new GradientStop(); blueGS.Color = Colors.Lime; What am I missing? Both of these colors belong to System.Windows.Media.Colors.

  • When to use an MS SQL instance vs. different database on same instance

    - by BoxerBucks
    We have some MS SQL servers that are setup with different instances on the same server to separate applciation DB's as well as some servers that are setup with all DB's on the same instance, just separated with security settings. When is it advisable to create a new instance for SQL server and install your DB's in that instance as opposed to just creating a new DB on the same instance and putting security around the database itself? Is there more to the decision that just a security aspect?
