  • jQuery center multiple dynamic images in different sized containers

    - by JVK Design
    So I've found similar questions but none that answer all the questions I have and I know there must be a simple jQuery answer to this. I've got multiple images that are being dynamically placed in their own containing div that have overflow:hidden, they need to fill their containing divs and be centered(horizontally and vertically) also. The containing divs will be different sizes as well. So in short: multiple different sized images fill and center in containing div. containing divs will be different sizes. will be used multiple times on a page. Hopefully this image helps explain what I'm after. Click here to view the image. HTML I'm using but can be changed <div class="imageHolder"> <div class="first SlideImage"> <img src="..." alt="..."/> </div> <div class="second SlideImage"> <img src="..." alt="..."/> </div> <div class="third SlideImage"> <img src="..." alt="..."/> </div> </div> And the CSS .imageHandler{ float:left; width:764px; height:70px; margin:1px 0px 0px; } .imageHolder .SlideImage{ float:left; position:relative; overflow:hidden; } .imageHolder .SlideImage img{ position:absolute; } .imageHolder .first.SlideImage{ width:381px; height:339px; margin-right:1px; } .imageHolder .second.SlideImage{margin-bottom:1px;} .imageHolder .second.SlideImage, .imageHolder .third.SlideImage { width: 382px; height: 169px; } Ask me anything if this doesn't make sense, thanks in advance

  • Dynamic webpage content

    - by SQLiteNoob
    I have a website with a jQuery UI navigation, and I've got ajax working to dynamically change content between html files. I'm basically just replacing the contents of certain div ids with the contents of other div ids. This still requires numerous HTML files and I was wondering if there was a way to have a single html file and load content into the main page from it instead? What about an xml file? Thanks for the tips and advice about best practices and possible solutions.

  • Dynamic HTML body width (over 100%)

    - by danixd
    I am creating a horizontal webpage and I am trying to make the body dynamically expand according to the content within it. I am building the website here: http://www.obliquo.co.uk/ As you can see it all works, but I am forced to setting a huge body width in pixel value. The content on the page will be changing all the time. If I don't set a width in pixels, the divs start bumping vertically, naturally.

  • getting database connectivity issue from only one part of my ASP.net project?

    - by Greg
    Hi, Something weird has started happening to my project with Dynamic Data. Suddenly I am now getting connection errors when going to the DD navigation pages, but things work fine on the default DD main page, and also other MVC pages I've added in myself work fine to the database. Any ideas? So in summary if I go to the following web pages: custom URL for my custom controller - this works fine, including getting database data main DD page from root URL - this works fine click on a link to a table maintenance page from the main DD page - GET DATABASE CONNECTIVITY ERROR Some items: * I'm using SQL Server Express 2008 * Doesn't seem to be any debug/error info in VS2010 at all I can see * Web config entry: <add name="Model1Container" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=GREG\SQLEXPRESS_2008;Initial Catalog=greg_development;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient"/> Error: Server Error in '/' Application.

  • What are basic programs like, recursion, Fibonacci, small trick programs?

    - by Mike
    This question may seem daft (I'm a new to 'programming' and should probably stop if this is the type of question I'm required to ask)... What are: "basic programs like, recursion, fibonacci, factorial, string manipulation, small trick programs"? I've recently read Coding Horror - the non programmer and followed the links to Kegel and How to get hired. Then I delved through some similar questions here (hence the block quote) and I realised that as a fully fledged non-programmer I probably wouldn't know if I knew recursion (or any of the others) because I wouldn't know what it looked like, or why it was used, and what the results would look like after it was used. I suppose I'm trying to get a picture of "the basics". What the principles are and why we learn them - where they'll be used and what result/s your looking for. If they'll be used as an interview question during my first interview sometime in 2020 I would like to look less ignorant than those 199 out of 200 who just don't know the how, or the why, of programming. As always...I'll get my coat. Thanks Mike

  • What does it mean that "Lisp can be written in itself?"

    - by Mason Wheeler
    Paul Graham wrote that "The unusual thing about Lisp-- in fact, the defining quality of Lisp-- is that it can be written in itself." But that doesn't seem the least bit unusual or definitive to me. ISTM that a programming language is defined by two things: Its compiler or interpreter, which defines the syntax and the semantics for the language by fiat, and its standard library, which defines to a large degree the idioms and techniques that skilled users will use when writing code in the language. With a few specific exceptions, (the non-C# members of the .NET family, for example,) most languages' standard libraries are written in that language for two very good reasons: because it will share the same set of syntactical definitions, function calling conventions, and the general "look and feel" of the language, and because the people who are likely to write a standard library for a programming language are its users, and particularly its designer(s). So there's nothing unique there; that's pretty standard. And again, there's nothing unique or unusual about a language's compiler being written in itself. C compilers are written in C. Pascal compilers are written in Pascal. Mono's C# compiler is written in C#. Heck, even some scripting languages have implementations "written in itself". So what does it mean that Lisp is unusual in being written in itself?

  • NSPredicate as a constraint solver?

    - by Felixyz
    I'm working on a project which includes some slightly more complex dynamic layout of interface elements than what I'm used to. I always feel stupid writing complex code that checks if so-and-so is close to such-and-such and in that case move it x% in some direction, etc. That's just not how programming should be done. Programming should be as declarative as possible! Precisely because what I'm going to do is fairly simple, I thought it would be a good opportunity to try something new, and I thought of using NSPredicate as a simple constraints solver. I've only used NSPredicate for very simple tasks so far, but I know that it capable of much more. Are there any ideas, experiences, examples, warnings, insights that could be useful here? I'll give a very simple example so there will be something concrete to answer. How could I use NSPredicate to solve the following constraints: viewB.xmid = (viewB.leftEdge + viewB.width) / 2 viewB.xmid = max(300, viewA.rightEdge + 20 + viewB.width/2) ("viewB should be horizontally centered on coordinate 300, unless its left edge gets within 20 pixels of viewB's right edge, in which case viewA's left edge should stay fixed at 20 pixels to the right of viewB's right edge and viewA's horizontal center get pushed to the right.") viewA.rightEdge and viewB.width can vary, and those are the 'input variables'. EDIT: Any solution would probably have to use the NSExpression method -(id)expressionValueWithObject:(id)object context:(NSMutableDictionary *)context. This answer is relevant.

  • Need some ignition for learning Embedded Systems

    - by Rahul
    I'm very much interested in building applications for Embedded Devices. I'm in my 3rd year Electrical Engineering and I'm passionate about coding, algorithms, Linux OS, etc. And also by Googling I found out that Linux OS is one of the best OSes for Embedded devices(may be/may not be). I want to work for companies which work on mobile applications. I'm a newbie/naive to this domain & my skills include C/C++ & MySQL. I need help to get started in the domain of Embedded Systems; like how/where to start off, Hardware prerequisites, necessary programming skills, also what kind of Embedded Applications etc. I've heard of ARM, firmware, PIC Micorcontrollers; but I don't know anything & just need proper introduction about them. Thanx. P.S: I'm currently reading Bjarne Struotsup's lecture in C++ at Texas A&M University, and one chapter in it describes about Embedded Systems Programming.

  • I can learn either C or Java, which one should I choose first? Should I take them concurrently?

    - by GR1000
    I realize this is a subject of hot debate, but I'm interested in opinions that relate to my specific situation. I want to learn the basics and fundamentals of programming, so I'm already taking a college course in general programming concepts. It isn't covering a specific language, but it's giving me a solid foundation that I can build upon when I move on to a class that teaches a specific language. My two options for a specific language are Java and C because those are the two languages taught at the college I want to take classes from. What I want to do is learn a complex language so that I can apply that knowledge to languages that I use, or will eventually use, in my current job building web pages: XHTML, CSS, JavaScript, PHP, XML, ActionScript. I'm not necessariy interested in becoming a Java developer or a C developer in the immediate future, but I do have aspirations of developing web applications and iPod/iPhone applications. So, basically, I'm looking for answers to these questions and the reasoning behind them: Do I take the introductory course in Java first, and then take the intro course in C, or Do I take C first and then take Java? Is there any reason not to take them concurrently? Should I skip C altogether as Java covers everything I need to know? EDIT: Thanks everyone for your thoughtful and insightful responses.

  • Want to add a functional language to my toolchest. Haskell or Erlang?

    - by sean.johnson
    I've been an OO/procedural guy my whole career except in school where I did a lot of logic programming (Prolog). I work on an amazing variety of projects (freelancer) and so I don't want the tools I know and understand to hold me back from using the right tool for the job. I've decided I should know a functional programming language. I've narrowed the field to Haskell and Erlang. What are the pros and cons, advantages and disadvantages, and major trade offs of Haskell and Erlang? How do I decide in a rational way, which is the better path? This is a big time investment, so I'd like to chose wisely. Is there a good case to be made for something else entirely? F#, Scala Ocaml? (BTW, I'm normally a Ruby/C/Obj.C guy, so I'm not terribly impressed or dependent on the JVM as a runtime. It's completely neutral to me. It's a fine runtime, I don't hold it for or against a language. I don't use Microsoft products though, so a .NET runtime would be a negative.)

  • Financial Market Developer dilemma...

    - by Sahat
    ...In the future I am planning to work in the financial sector as a programmer. I have a couple of options right now (1 or 2): Learn and master .NET since presumably that's widely used in that industry OR Learn the programming concepts, learn algorithms, learn a little bit of c,c++,c#,java,objective-c,sql,oracle,cobol - in other words learn the fundamental principles that tie all programming languages together without going too deep in any particular language. Someone has told me that most of the time as a programmer you won't be writing any code, but instead maintaing and existing code that people before you have built. Does that mean I don't really need to master any specific language and as long as I have general concepts it'll be good enough? If you or if you know someone who has worked in the financial industry as a software developer could you please share the experience and what is the daily routine consists of? Also what should I be learning right now while I am still young and in college? Do I have to thoroughly understand the market and the current economy? What about Oracle or SQL Databases - do I need to know them inside out as a programmer? Thanks if you have anything else to add that I have not mentioned then please do so! Thanks in advance!

  • When returning from a period of not programming, do you find you've improved?

    - by Jon Purdy
    It seems as though whenever I take an extended break from programming—whether to pursue other interests or simply because I fall out of the habit for a while—I invariably find that when I return to a project and set to coding, I come with an abundance of new ideas, novel approaches, and just plain better code. It may be because I have a lot of other creative interests besides programming, and my mind likes to find correlation and crossover between them, so while I'm doing one thing, in the back of my mind I'm usually also applying it to another. So what's your experience? Do you ever return from a break (whether intentional or not) feeling not only refreshed, but also somehow noticeably improved? Is it actually the norm?

  • Is 4-5 years the “Midlife Crisis” for a programming career?

    - by Jeff
    I’ve been programming C# professionally for a bit over 4 years now. For the past 4 years I’ve worked for a few small/medium companies ranging from “web/ads agencies”, small industry specific software shops to a small startup. I've been mainly doing "business apps" that involves using high-level programming languages (garbage collected) and my overall experience was that all of the works I’ve done could have been more professional. A lot of the things were done incorrectly (in a rush) mainly due to cost factor that people always wanted something “now” and with the smallest amount of spendable money. I kept on thinking maybe if I could work for a bigger companies or a company that’s better suited for programmers, or somewhere that's got the money and time to really build something longer term and more maintainable I may have enjoyed more in my career. I’ve never had a “mentor” that guided me through my 4 years career. I am pretty much blog / google / self taught programmer other than my bachelor IT degree. I’ve also observed another issue that most so called “senior” programmer in “my working environment” are really not that senior skill wise. They are “senior” only because they’ve been a long time programmer, but the code they write or the decisions they make are absolutely rubbish! They don't want to learn, they don't want to be better they just want to get paid and do what they've told to do which make sense and most of us are like that. Maybe that’s why they are where they are now. But I don’t want to become like them I want to be better. I’ve run into a mental state that I no longer intend to be a programmer for my future career. I started to think maybe there are better things out there to work on. The more blogs I read, the more “best practices” I’ve tried the more I feel I am drifting away from “my reality”. But I am not a great programmer otherwise I don't think I am where I am now. I think 4-5 years is a stage that can be a step forward career wise or a step out of where you are. I just wanted to hear what other have to say about what I’ve mentioned above and whether you’ve experienced similar situation in your past programming career and how you dealt with it. Thanks.

  • AI Game Programming : Bayesian Networks, how to make efficient?

    - by Mahbubur R Aaman
    We know that AI is one of the most important part of Game Programming. Bayesian networks is one of the core part of AI at Game Programming. Bayesian networks are graphs that compactly represent the relationship between random variables for a given problem. These graphs aid in performing reasoning or decision making in the face of uncertainty. Here me, utilizing the monte carlo method and genetic algorithms. But tooks much time and sometimes crashes due to memory. Is there any way to implement efficiently?

  • Any good tutorials all this web programming stuff for a GUI person? [closed]

    - by supercheetah
    For some reason, I am having a hard time understanding all this web programming stuff--from AJAX to JSON, etc. I've got plenty of experience programming GUIs. I'm currently working on a project in Python, and I thought that maybe I could just use PyJS (since it's GWT for Python, it uses an API that's very familiar to experienced GUI programmers like myself) to compile it with a Javascript interface on top, but alas, the compiler gave me a spectacular failure. It's obviously not meant to handle much of any Python beyond itself, and some of the core Python library. It would have been nice if it could, but I will admit, it would have been the lazy way to do it. I tried to learn Django, but for some reason, I'm just having a hard time understanding the tutorial on their website, and what it's all doing. Maybe it's not the best framework to learn, perhaps? Anyway, does anyone have a good primer/tutorial explaining all this stuff, especially for Python, and especially for someone coming from a GUI background?
