  • Div in HTML not floating left with CSS

    - by rusty009
    My div with class name 'header-body-right' doesn't seem to be floating to the left of my div named 'header-body-centre' and I can't understand why, here is my HTML, <!DOCTYPE HTML> <HTML> <HEAD> <TITLE> </TITLE> <meta charset="UTF-8" /> <link href="main.css" rel="stylesheet" type="text/css"> <META NAME="Generator" CONTENT="Notepad"> <META NAME="Author" CONTENT="00"> <META NAME="KEYWORDS" CONTENT="" /> <META NAME="DESCRIPTION" CONTENT="" /> </HEAD> <BODY> <div class="header-top"> </div> <div class="header-body"> <div class="header-body-centre"> <div class="logo"> <img src="logo.png" /> </div> </div> <div class="header-body-right"> test </div> </div> <div class="navbar"> </div> <div class="content-container"> </div> </BODY> </HTML> The CSS I am using for the code is posted below, body { margin:0px; padding:0px; } .header-top { height:11px; width:100%; background-image: url('HeaderTopNav.png'); background-repeat: repeat-x; } .header-body { width:100%; height:100px; } .header-body-centre { margin: 0 auto; height:100%; width:70%; } .header-body-right { width:15%; height:100px; float:left; } .navbar { height:35px; width:auto; border: 1px solid green; } .logo { margin-top:35px; float:left; } .quickNav { float:right; } .container { margin: 0 auto; background-color: #fff; border: 2px solid #c9c8c8; border-bottom: none; height:auto; overflow:hidden; width: 1000px; clear:both; } Can anyone see why? I have tried floating the header-bosy-centre and decreasing the width of the header-body-right but nothing works. Can anyone see what I have done wrong? I am out of ideas. Thanks.

  • Looking to eventually build a smartphone app...

    - by Brian L
    Hi all- I'm a young, inexperienced programmer (I've had a year of Java, some MATLAB, and HTML/CSS in school) but I've decided that to get better, I'm making it my goal to produce a simple smartphone app of some kind this year- probably either webOS or Android since I'm on a PC and can't afford a Mac just to write an iPhone app. So my question is, where do I start? I've read the threads about How to Write for Android and such, but I'm not sure I have enough Java experience to just jump right in. And then there's webOS which is based on JavaScript, correct? I guess I'd just like some input from more experienced folks. I have some Barnes and Noble book credit I'm looking to get rid of too, so if there's a guide you think would be useful, feel free to request. tl;dr: Programming newbie ultimately wants to build a simple smartphone app. Where do I start?

  • BB Code Parser (in formatting phase) with jQuery jammed due to messed up loops most likely

    - by Oskar
    Greetings everyone, I'm making a BB Code Parser but I'm stuck on the JavaScript front. I'm using jQuery and the caret library for noting selections in a text field. When someone selects a piece of text a div with formatting options will appear. I have two issues. Issue 1. How can I make this work for multiple textfields? I'm drawing a blank as it currently will detect the textfield correctly until it enters the $("#BBtoolBox a").mousedown(function() { } loop. After entering it will start listing one field after another in a random pattern in my eyes. !!! MAIN Issue 2. I'm guessing this is the main reason for issue 1 as well. When I press a formatting option it will work on the first action but not the ones afterwards. It keeps duplicating the variable parsed. (if I only keep to one field it will never print in the second) Issue 3 If you find anything especially ugly in the code, please tell me how to improve myself. I appriciate all help I can get. Thanks in advance $(document).ready(function() { BBCP(); }); function BBCP(el) { if(!el) { el = "textarea"; } // Stores the cursor position of selection start $(el).mousedown(function(e) { coordX = e.pageX; coordY = e.pageY; // Event of selection finish by using keyboard }).keyup(function() { BBtoolBox(this, coordX, coordY); // Event of selection finish by using mouse }).mouseup(function() { BBtoolBox(this, coordX, coordY); // Event of field unfocus }).blur(function() { $("#BBtoolBox").hide(); }); } function BBtoolBox(el, coordX, coordY) { // Variable containing the selected text by Caret selection = $(el).caret().text; // Ignore the request if no text is selected if(selection.length == 0) { $("#BBtoolBox").hide(); return; } // Print the toolbox if(!document.getElementById("BBtoolBox")) { $(el).before("<div id=\"BBtoolBox\" style=\"left: "+ ( coordX + 5 ) +"px; top: "+ ( coordY - 30 ) +"px;\"></div>"); // List of actions $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_bold.png\" alt=\"B\" title=\"Bold\" /></a>"); $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_italic.png\" alt=\"I\" title=\"Italic\" /></a>"); } else { $("#BBtoolBox").css({'left': (coordX + 3) +'px', 'top': (coordY - 30) +'px'}).show(); } // Parse the text according to the action requsted $("#BBtoolBox a").mousedown(function() { switch($(this).children(":first").attr("alt")) { case "B": // bold parsed = "[b]"+ selection +"[/b]"; break; case "I": // italic parsed = "[i]"+ selection +"[/i]"; break; } // Changes the field value by replacing the selection with the variable parsed $(el).val($(el).caret().replace(parsed)); $("#BBtoolBox").hide(); return false; }); }

  • Chrome and its Spellcheck -- How Hard Would This Be To Implement

    - by bobber205
    From a programmer's perspective. The dictionary in chrome, Google's "own" browser, does not have the same dictionary as their search engine. Countless times I have right clicked on a poorly misspelled word only to have no correct spelling appear. I Google the word and almost 100% of the time it knows what I was trying to type. :) I realize there are probably very good reasons for this, but why can't Chrome simply Google for a word when you right click on it when it can't find a correct spelling. I am sometimes a bad speller and it would be really nice if the spell check in Chrome at least utilized Google's landmark product to provide more accurate word spelling lookups. How hard must this be to implement or are there other reasons you think they are not?

  • SOAP - What's the point?

    - by DanSingerman
    I mean, really, what is the point of SOAP? Web services have been around for a while, and for a while it seemed that the terms 'SOAP' and 'Web service' were largely interchangeable. However SOAP always seemed unwieldy and massively overcomplicated to me. Then REST came along, and suddenly web services made sense. As Joel Spolsky says, give a programmer a REST URL, and they can start playing with the service right away, figuring it out. SOAP is obfuscated behind WSDLs and massively verbose XML, and despite being web based, you can't do anything as simple as access a SOAP service with a web browser. So the essence of my question is: Are there any good reasons to ever choose SOAP over REST? Are you working with SOAP now? Would it be better if the interface was REST? Am I wrong?

  • What benefits can Java developer have from moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse on it, so there will be no big difference. Guys, who use Java on *NIX, could you please give me some real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • OpenAL device, buffer and context relationship

    - by Markus
    I'm trying to create an object oriented model to wrap OpenAL and have a little problem understanding the devices, buffers and contexts. From what I can see in the Programmer's Guide, there are multiple devices, each of which can have multiple contexts as well as multiple buffers. Each context has a listener, and the alListener*() functions all operate on the listener of the active context. (Meaning that I have to make another context active first if I wanted to change it's listener, if I got that right.) So far, so good. What irritates me though is that I need to pass a device to the alcCreateContext() function, but none to alGenBuffers(). How does this work then? When I open multiple devices, on which device are the buffers created? Are the buffers shared between all devices? What happens to the buffers if I close all open devices? (Or is there something I missed?)

  • Multiple developers on a Titanium project

    - by Cybear
    I'm making an iPhone app with Appcelerator Titanium and I want to share the source code with a few more programmers. I will use a SCM repository which at some point might be open to the general public. Now my question is, are there any files which I should not commit to the repository? In project root I can tell that tiapp.xml and mainfest are telling the app GUID, is there any reason for me to keep that private? (this value is also shown many places in the build/ folder) I've added everything in the Resources/ folder. If I skip the build/iphone/build/ folder, will developers still be able to build the project? Side question - When another programmer downloads this code, it seems to me that (s)he has to have the same directory structure as I do? Any workarounds for this?

  • How to get cheap version control?

    - by gotch4
    Hello, I'm a programmer, contractor, self experimenter and so on. I'd need to have cheap version control. I've been working with Subversion and recently with Mercurial. I've seen around many cheap hosting but, even if they are great (like BitBucket), many of them don't allow many private projects (1 or 2). Much of the code I need to keep on VC is not open, maybe because it is stuff I'm working on for clients, or maybe because it's code I usually need for my development, but it is not intended and usable as a open source project. Now, I've a cheap web hosting, with unlimited space and free mysql. I CAN'T install Mercurial or SVN on those machinese, but I was asking myself if is it there a way to use a common CVS with it, with "common" I mean something that has its good IDE plugins (Eclipse or Netbeans) that may avoid me to write commands by hand. Thank you

  • How to code for Alternate Course AKA Rainy Day Scenary?

    - by janetsmith
    Alternate course is something when user doesn't do what you expected, e.g. key in wrong password, pressing back button, or database error. For any programming project, alternate course accounts for more than 50% of a project timeline. It is important. However, most computer books only focus on Basic Course (when everything goes fine). Basic course is rather simple, compared to Alternate course, because this is normally given by client. Alternate course is what we, as a programmer or Business Analyst needs to take care of. Java has some built-in mechanism (try-catch) to force us to handle those unexpected behavior. The question is, how to handle them? Any pattern to follow? Any guideline or industry practice for handling alternate course?

  • SQL Server: Primary Key Schema Largely Guid but Sometimes Integer Types...

    - by Code Sherpa
    OK, this may be a silly question but... I have inherited a project and am tasked with going over the primary key relationships. The project largely uses Guids. I say "largely" because there are examples where tables use integral types to reflect enumerations. For example, dbo.MessageFolder has MessageFolderId of type int to reflect public emum MessageFolderTypes { inbox = 1, sent = 2, trash = 3, etc... } This happens a lot. There are tables with primary keys of type int which is unavoidable because of their reliance on enumerations and tables with primary keys of type Guid which reflect the primary key choice on the part of the previous programmer. Should I care that the PK schema is spotty like this? It doesn't feel right but does it really matter? If this could create a problem, how do I get around it (I really can't move all PKs to type int without serious legwork and I have never heard of enumerations that have guid values)? Thanks.

  • How to automate the finding of an M value along a route

    - by Heather Taylor
    Kirk Kuykendall had given a script example a few years back in an ESRI forum http://forums.esri.com/Thread.asp?c=93&f=996&t=88246&mc=4 as to how to find the M (measure) value of a point in a shapefile along a route when you clicked on the point. This is very handy, BUT..I have 1500 points that I need M values for. Is there a way to automate this type of thing? I need the M values for the points to create linear events on the route.

  • Windows 8 isn't detecting PS3 eye

    - by JonFriesen
    I have the PS3 Eye web cam installed with drivers from Code Laboratories, which comes with a test program. When I open the test program it shows a clear picture from the webcam. Every other program does not detect a webcam. The cam shows in my device manager and as installed correctly. My question is, is there a flag or something like that I can set that will show Windows 8 that this device is in fact a camera and is working. Here is a picture of the test program that comes loaded with the drivers and the windows 8 camera app. Thanks for the help! **Here is a pic, I can't integrated because I haven't posted enough on superuser :P http://i48.tinypic.com/6qyw6t.png

  • Is Python appropriate for algorithms focused on scientific computing?

    - by gmatt
    My interests in programming lie mainly in algorithms, and lately I have seen many reputable researchers write a lot of their code in python. How easy and convenient is python for scientific computing? Does it have a library of algorithms that compares to matlab's? Is Python a scripting language or does it compile? Is it a great language for prototyping an algorithm? How long would it take me to learn enough of it to be productive provided I know C well and OO programming somewhat? Is it OO based? Sorry for the condensed format of questions, but I'm very curious and was hoping a more experienced programmer could help me out.

  • how to customize debian installation cd for your needs

    - by Frank
    I have with me a Debian CD, which I want to customize for my own needs. I have extracted the CD and started to change some parts of it, e.g Splash screen (splash.png) installer Title (through isolinux.cfg) etc These are the things that I want to do: Change the Splash logo at start up of installation to have my own (which is done) Change the grub boot parameters to use my comapny name on it. Change the set of packages in it, so that I can have my own set of packages in it and only those packages are installed Do some post installation steps Customize it's startup and login screen to have my company name. After I am done with this customization, I need to build its live installer CD so that I can install it on my own, on any other system.

  • C# Lists, Foreach, and Types

    - by user406470
    I was wondering if there is a version of foreach that checks only for a specific type and returns it. For example consider this class tree: org.clixel.ClxBasic - org.clixel.ClxObject - org.clixel.ClxSprite - WindowsGame1.test Then consider this code public List<ClxBasic> objects = new List<ClxBasic>(); foreach(GroupTester tester in objects) { tester.GroupTesterOnlyProperty = true; } tester.GroupTesterOnlyProperty is a property created in GroupTester. Is there some way to make something like this work, like an overload of foreach, or another snippet that might help me? I want to make it easy for a programmer to sort through the lists grabbing only what type they need.

  • How to make nginx only respond to one domain?

    - by larryzhao
    I am pretty new to nginx, I host my rails application on nginx+passenger. I want my website to be accessible to only one domain. So I set my nginx conf like the following: server { listen 80; server_name mydomain.com www.mydomain.com; root /var/deploy/myapp/current/public; passenger_enabled on; location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ { expires 1y; add_header Cache-Control public; } } I specify the server_name directive, but still, it answers anything which points to this IP and I could see that in the access.log that it answers to other domain names. Is there anything I am doing wrong?

  • Some good websites to learn about JavaScript and programming architecture?

    - by Jack Roscoe
    I'm not sure if 'architecture' is the correct term, but I've been looking for some articles online which talk about programming design and more about how best to use languages such as JavaScript in a code design sense rather than the actual syntax itself. I have found many websites but a lot seem to be very out dated, and I'm not sure what developments have taken place with JavaScript over the years so do not know how old is too old. If anybody could suggest some great websites, or maybe specific articles you think would be useful, that would be highly appreciated. I am a beginner programmer currently using JavaScript with XML and of course HTML & CSS, and I'm currently trying to get further into and learn more about web development.

  • Is there a smart web developer language skill combination?

    - by Cryo
    I'm no newbie to programming, but I'm making the move to a career in web development, and I've noticed that so many job postings have different combinations of skill requirements: (PHP, C#, XML, XHTML/CSS, ASP, .NET, jQuery, YUI, Joomla, Ruby, Perl, Python, Java, Javascript... the list goes on.) As of now, I've started learning XHTML, CSS, JavaScript, jQuery, PHP, and mySQL, but with so many combinations, I want to plan ahead to have a marketable combination of skills as early on as possible. Am I on the right path? What is vital for a marketable web programmer's arsenal? Thanks for your thoughts.

  • Caffeine and Stimulant Usage

    - by Jon Purdy
    Let's see how many of us fit the old stereotype, shall we? Do you typically use caffeine when programming? During the day or at night? How frequently do you pull all-nighters? Do you use caffeine when you do stay up late? Do you prefer to have a large amount of caffeine all at once, or small amounts over a longer period of time? Do you use energy drinks, 5-hour energy shots, coffee, tea, or caffeine pills? How about other stimulants such as amphetamines? For instance, I've known a programmer who dabbled in speed because they believed it increased their ability to focus on programming, though happily they're clean now and quite honest about the whole experience. Share, discuss, find the Ballmer Peak of caffeine, enjoy. Happy Easter.

  • Learning to think in the Object Oriented Way

    - by SpikETidE
    Hi Everyone.... I am a programmer trying to learn to code in the object oriented paradigm... I mainly work with PHP and i thought of learning the zend framework... So, felt I need to learn to code in OO PHP.... The problem is, having done code using functions for quite a long time, i just can't get my head to think in the OO way.... Also felt that probably I am not the only one facing this problem since the beginning of time... So, how did you people learn object oriented programming... especially how did you succeed in "unlearning" to code using functions... and learn to see you code as objects...? Is there any good resource books or sites where one could find help...?? Thanks for sharing your knowledge and experiences...

  • Best performance approach to history mechanism?

    - by Royi Namir
    We are going to create History Mechanism for our changes in DB (DART in pic) via Triggers. we have 600 tables. Each record that will be changed - the trigger will insert the deleted one into XXX. regarding to the XXX : option 1 : clone each table in "Dart" DB and each table now will have a "sister table" e.g. : Table1 will have Table1_History problems : we will have 1200 tables programmer can do mistakes by working on wrong tables... option 2 : make a new DB (DART_2005 in pic) and the history tables will be there option 3 : use linked server which stores the Db which will contain the history tables. question : 1) which option gives the best performance ( I guess 3 is not - but is it 1 or 2 or same ?) 2) Does option 2 is acting like "linked server" ( in queries we will need to select from both DB's...) 3) What is the best practice approach ?

  • Rails destroy confirm with Jquery AJAX

    - by Mike
    I have got this working for the most part. My rails link is: <%= link_to(image_tag('/images/bin.png', :alt => 'Remove'), @business, :class => 'delete', :confirm => 'Are you sure?', :id => 'trash') %> :class = "delete" is calling an ajax function so that it is deleted and the page isn't refreshed that works great. But because the page doesn't refresh, it is still there. So my id trash is calling this jquery function: $('[id^=trash]').click(function(){ var row = $(this).closest("tr").get(0); $(row).hide(); return false; }); Which is hiding the row of whatever trash icon i clicked on. This also works great. I thought I had it all worked out and then I hit this problem. When you click on my trash can I have this confirm box pop up to ask you if you are sure. Regardless of whether you choose cancel or accept, the jquery fires and it hides the row. It isn't deleted, only hidden till you refresh the page. I tried changing it so that the prompt is done through jquery, but then rails was deleteing the row regardless of what i choose in my prompt because the .destroy function was being called when the prompt was being called. My question really is how can i get the value to cancel or accept from the rails confirm pop up so that in my jquery I can have an if statement that hides if they click accept and does nothing if they click cancel. EDIT: Answering Question below. That did not work. I tried changing my link to: <%= link_to(image_tag('/images/bin.png', :alt => 'Remove'), @business, :class => "delete", :onclick => "trash") %> and putting this in my jquery function trash(){ if(confirm("Are you sure?")){ var row = $(this).closest("tr").get(0); $(row).hide(); return false; } else { //they clicked no. } } But the function was never called. It just deletes it with no prompt and doesn't hide it. But that gave me an idea. I took the delete function that ajax was calling $('a.delete').click (function(){ $.post(this.href, {_method:'delete'}, null, "script"); $(row).hide(); }); And modified it implementing your code: remove :confirm = 'Are you sure?' $('a.delete').click (function(){ if(confirm("Are you sure?")){ var row = $(this).closest("tr").get(0); $.post(this.href, {_method:'delete'}, null, "script"); $(row).hide(); return false; } else { //they clicked no. return false; } }); Which does the trick.
