  • How do i map this in NHibernate

    - by Andrew Smith
    I Have two classes, Survey and Poll classes. Also I have Question and Question Choice classes. How do I map these so I come out with particular table formats. here is the classes involved. public class Survey { public IList<Question> Questions { get; private set; } } public class Poll { public Question Question { get; set; } } public class Question { public string Text { get; set; } public IList<QuestionChocie> Choices { get; private set; } } public class QuestionChoice { public string Text { get; set; } } The resulting tables that I'm shooting for include the following Surveys- a table of survey information. Polls - a table of polls information. SurveyQuestions -a table of survey questions. PollQuestions - a table of poll questions. SurveyChoices - a table of the question choices for the surveys. PollChoices - a table of the question choices for the survey. preferably i really want to know for fluent nhibernate, or just mapping xml is fine too.

  • CTRL+mouse wheel in gvim (windows) not paging

    - by andrew
    Hello, I'm loving vim, but one thing that's bugging me is that when I hold the control key and mouse wheel up or down, the window scrolls normally when the bindings are telling it to page up/down. I'm using the exact same vimrc file (and plugins) on one of my linux machines and the CTRL+mouse wheel does page up down (as opposed to just normally scrolling like in windows). Is there some way to force gvim to response to a ctrl+MouseUp/Down event? It seems to be ignoring it in windows ='[

  • Optimization of a c++ matrix/bitmap class

    - by Andrew
    I am searching a 2D matrix (or bitmap) class which is flexible but also fast element access. The contents A flexible class should allow you to choose dimensions during runtime, and would look something like this (simplified): class Matrix { public: Matrix(int w, int h) : data(new int[x*y]), width(w) {} void SetElement(int x, int y, int val) { data[x+y*width] = val; } // ... private: // symbols int width; int* data; }; A faster often proposed solution using templates is (simplified): template <int W, int H> class TMatrix { TMatrix() data(new int[W*H]) {} void SetElement(int x, int y, int val) { data[x+y*W] = val; } private: int* data; }; This is faster as the width can be "inlined" in the code. The first solution does not do this. However this is not very flexible anymore, as you can't change the size anymore at runtime. So my question is: Is there a possibility to tell the compiler to generate faster code (like when using the template solution), when the size in the code is fixed and generate flexible code when its runtime dependend? I tried to achieve this by writing "const" where ever possible. I tried it with gcc and VS2005, but no success. This kind of optimization would be useful for many other similar cases.

  • IntentService android download and return file to Activity

    - by Andrew G
    I have a fairly tricky situation that I'm trying to determine the best design for. The basics are this: I'm designing a messaging system with a similar interface to email. When a user clicks a message that has an attachment, an activity is spawned that shows the text of that message along with a paper clip signaling that there is an additional attachment. At this point, I begin preloading the attachment so that when the user clicks on it - it loads more quickly. currently, when the user clicks the attachment, it prompts with a loading dialog until the download is complete at which point it loads a separate attachment viewer activity, passing in the bmp byte array. I don't ever want to save attachments to persistent storage. The difficulty I have is in supporting rotation as well as home button presses etc. The download is currently done with a thread and handler setup. Instead of this, I'd like the flow to be the following: User loads message as before, preloading begins of attachment as before (invisible to user). When the user clicks on the attachment link, the attachment viewer activity is spawned right away. If the download was done, the image is displayed. If not, a dialog is shown in THIS activity until it is done and can be displayed. Note that ideally the download never restarts or else I've wasted cycles on the preload. Obviously I need some persistent background process that is able to keep downloading and is able to call back to arbitrarily bonded Activities. It seems like the IntentService almost fits my needs as it does its work in a background thread and has the Service (non UI) lifecycle. However, will it work for my other needs? I notice that common implementations for what I want to do get a Messenger from the caller Activity so that a Message object can be sent back to a Handler in the caller's thread. This is all well and good but what happens in my case when the caller Activity is Stopped or Destroyed and the currently active Activity (the attachment viewer) is showing? Is there some way to dynamically bind a new Activity to a running IntentService so that I can send a Message back to the new Activity? The other question is on the Message object. Can I send arbitrarily large data back in this package? For instance, rather than send back that "The file was downloaded", I need to send back the byte array of the downloaded file itself since I never want to write it to disk (and yes this needs to be the case). Any advice on achieving the behavior I want is greatly appreciated. I've not been working with Android for that long and I often get confused with how to best handle asynchronous processes over the course of the Activity lifecycle especially when it comes to orientation changes and home button presses...

  • JQUERY: Multiplying input elements select box and radio boxes and hidden inputs

    - by Andrew Tan
    Evening, I'm tyring to multiply different input elements but for some reason it's giving me a NAND error. As the user selects, check or modify the values of any element. This should change the total amount. http://jsfiddle.net/aQ5K8/ <select name="select"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> </select> <input name="radio" type="radio" id="radio" value="10" tvalue="100" /> <input name="radio" type="radio" id="radio" value="20" tvalue="200" /> <label id="Total"></label> Also if you take a look at the jsfiddle code i have tvalue=100 and the other is =200 as a custom attributes, how would I access that instead of accessing the regular html value. Thank you.

  • Firebug shows error "_11 is undefined"

    - by Andrew
    Actually that's it. What does this error mean? I've googled on it, but found nothing. This error appears in firebug console after the page is loaded, or when i click on tabs. It does not prevent the execution of another JavaScript code, but the nature of it is mysterious for me.

  • jquery load function problem

    - by andrew
    Hi, i have a select box like that <select name="sehirler_post" id="sehirler_post"> i am getting values via jquery. i know two different ways to get values. first one is : var sehirler_post = jQuery('select#sehirler_post').attr('value'); second one is: jQuery('#sehirler_post ').val() and finally here is my problem, i have something like this: jQuery("#okay").load("ajax_post_category.php?okay="+id+""); i would like to use selectbox value instead of id (okay="+id+"). so, i must change +id+ part with select box value. however i can not do it.. i tried to do like that: jQuery("#okay").load("ajax_post_category.php?okay="+jQuery('#sehirler_post').val()+""); it did not work. there must be a way, so i can use selectbox value instead of id in my load function. if anyone helps me, ill be so glad. regards

  • nonatomic property in model class when using NSOperationQueue (iPhone)?

    - by Andrew B.
    I have a custom model class with an NSMutableData ivar that will be accessed by custom NSOperation subclasses (using an NSOperationQueue). I think I can guarantee thread-safe access to the ivar from multiple NSOperations by using dependencies, and I can guarantee that I don't access the ivar from other code (say my main app thread) by waiting until the Q has finished all operations. Should I use a nonatomic property specification, or leave it atomic? Is there a significant impact on performance?

  • MySQL Returns wrong values on SELECT statement

    - by Andrew K
    All, I'm wondering if this is a MySQL bug, but since I've seen others playing with larger numbers than this, I'm thinking I'm doing something wrong here. Here is my table structure for the table I'm querying: mysql describe ipspace6\G ************* 1. row ************* Field: id Type: decimal(39,0) unsigned Null: NO Key: Default: NULL Extra: ************* 2. row ************* Field: addr Type: decimal(39,0) unsigned Null: NO Key: PRI Default: 0 Extra: ************* 3. row ************* Field: netmask Type: decimal(39,0) unsigned Null: NO Key: Default: 0 Extra: ************* 4. row ************* Field: subnet Type: int(4) Null: NO Key: Default: NULL Extra: Now, I run a simple SELECT statement against the "id" column: mysql SELECT id FROM ipspace6 WHERE id='50552019118453823914642686339427860480'; +----------------------------------------+ | id | +----------------------------------------+ | 50552019118453823730175245602332344320 | | 50552019118453823730175245602332344320 | | 50552019118453823914642686339427860480 | | 50552019118453823914642686339427860480 | +----------------------------------------+ ...What the heck is going on here? Two of these results are valid, and two definitely are not. It's not like I'm doing some super-complex nested query or anything, this is simple stuff, and it's driving me insane. Help, anyone?

  • Post-back + Page Refresh. Post/Redirect/Get pattern alternatives?

    - by Andrew Florko
    When user posts back a web form and then tries to refresh the page - dialog "would you like to resend information" pops up (Opera works silently though). To avoid this we can redirect browser to the page we'd like to show after postback. Now, when user refreshes the page, he duplicates get-request and no pop-ups. Everything is ok but post/redirect/get approach requires additional roundtrip. Is there better alternatives. Send form data with ajax aynchronously, for example? Thank you in advance!

  • Meteor Deps - Running a Client Side Func

    - by Andrew Plummer
    I'm struggling to get a handle on Meteor deps, in order to be specific my use case is: 2) When collection is changed, I want to run a jQuery function on the client side I think deps are what I'm looking for, but at the moment I have only just used: Template.templateName.set () -> return Set.find({}) ...in terms of reactivity. A solution which simply console.log's the collection each time it is changed would be more that enough.

  • [PHP, CSS, & ?] fixed width div, resizing text on the fly based on length

    - by Andrew Heath
    Let's say you've got a simple fixed-width layout that pulls a title from a MySQL database. CSS: #wrapper { width: 800px; } h1 { width: 100%; } HTML: <html> <body> <div id="wrapper"> <h1> $titleString </h1> </div> </body> </html> But the catch is, the length of the title string pulled from your MySQL database varies wildly. Sometimes it might be 10 characters, sometimes it might be 80. It's possible to establish a min & max character count. How, if at all possible, do I get the text-size of my <h1>$titleString</h1> to enlarge/decrease on-the-fly such that the string is only ever on one line and best fit to that line length? I've seen a lot of questions about resizing the div - but in my case the div must always be 100% (800px) and I want to best-fit the title. Obviously a maximum text-size value would have to be set so 5 character strings don't become gargantuan. Does anyone have a suggestion? I'm only using PHP/MySQL/CSS on this page at the moment, but incorporation of another language is fine if it means I can solve the problem. The only thing I can think of is a bruteforce approach whereby through trial and error I establish acceptable string character count ranges matched with CSS em sizes, but that'd be a pretty ugly implementation from the code side.

  • Aggregating and displaying content from hundreds of RSS feeds

    - by Andrew LeClair
    I'd like to build a website that aggregates and displays content from hundreds of RSS feeds. The feeds will be from different sites: Twitter, Flickr, Tumblr, etc, so the content will be very heterogenous. In a perfect world — and this is more of a side issue — I would like to allow other people to help manage the list of feeds and assign tags to the content from each individual feed so that you can filter the items that are displayed. What I've tried so far: Google Feeds API – I thought this would be the answer, but unless I'm missing something, the FeedController will only output the collected feed content as separate lists. Is there any way to ask the Google Feeds API to aggregate and sort the content from many RSS feeds before displaying? Yahoo! Pipes – This also seemed like a good solution at first. I setup a Pipe that accesses a list of RSS feeds stored in a Google Doc spreadsheet and then aggregates the content. However, the output leaves a lot to be desired; Tumblr video posts, for example, only show a title and a permalink to the post, the embedded Youtube video is lost. PHP – I've seen this question, which looks like a good approach. I'm less proficient in PHP, so although I'm willing to learn, I'd ideally like to find a different approach. Any thoughts? Thanks.

  • Haskell type signature with multiple type somethings (predicates?, for example Eq a =>)

    - by Andrew
    I'm not sure if type predicates is the right term, in fact I've never learned the word for this, so an edit to correct would be helpful - I'm referring to when you give the tipe of function f :: a -> b and you want to say a is a Eq and you say f :: Eq a => a -> b, the name for Eq a => - this is the thing i called a type predicate. My question, though, is how to have multiple of these, so if A is an Eq and B is a Num, I could say either f :: Eq a => a -> b or f :: Num b => a -> b. So, how can I have Eq a => and Num b => at the same time? f :: Eq a => Num b => a -> b, f :: Eq a -> Num b => a -> b, and f :: Eq a, Num b => a -> b all didn't do what I wanted.

  • Determining whether one array contains the contents of another array in ruby

    - by Andrew Grimm
    In ruby, how do I test that one array not only has the elements of another array, but contain them in that particular order? correct_combination = [1, 2, 3, 4, 5] [1, 5, 8, 2, 3, 4, 5].function_name(correct_combination) # => false [8, 10, 1, 2, 3, 4, 5, 9].function_name(correct_combination) # => true I tried using include, but that is used to test whether [1,2,3].include?(2) is true or not.

  • JQuery. Layout is shaking during animation

    - by Andrew Florko
    Hello everybody, JQuery accordion animation (as well as simple hides / shows) looks weird with some browsers (IE, Opera). But Fire Fox and Chrome renders animation perfectly without artifacts. Html layout tends to shake with IE / Opera during animation as if surrounding paddings / margins are changed for small random value. How can I minimize this effect. Is it jquery bug or browsers issue?

  • Align text with bottom as it comes in during a chat?

    - by Andrew
    I'm building a custom web chat application, and while I have the basics worked out, I've been wondering if this was possible... right now, the chat comes in at the top of the div, and when it reaches the bottom, the div starts scrolling. This works. This is great. But I was wondering if it was possible to create it more like an IRC client, where the chat comes in initially at the bottom of the div, then each new line comes in below the old ones, etc, and again, when the div is full, it starts scrolling. I've managed to get part of this working: I can get it displaying this way. But I can't find a way to scroll it; either the scroll doesn't appear (when there's no overflow on the inner, text div, despite there being an overflow on the outer, container div), or it's confined to the width of the text rather than the width of the container div. Some options I've tried: <div id="chatbox" style="overflow: auto; position: relative; width: 100%; height: 400px;"> <div id="chatmessages" style="overflow: auto; position: absolute; bottom: 0;"></div></div> This has the text appear properly at the bottom, but no scrollbar ever appears. <div id="chatbox" style="overflow: auto; position: relative; width: 100%; height: 400px;"> <div id="chatmessages" style="overflow: scroll; position: absolute; bottom: 0;"></div></div> This has the text appear properly at the bottom, and a scrollbar appears, but it's only ever as wide as the text, even if width=100%... and when the text reaches the top, the scrollbar remains gray. Basically, do I want the scrollbar on the inner or the container div, is this even possible, how do I force it to work, and am I going about this entirely wrong?
