  • Rounded Corners Image Change on Hover

    - by Sarfraz
    Hello, I created a rounded box/button and sliced its first corner, the middle bar (which repeats horizontally to adjust the width of the button text/content) and the last corner and used following markup: <div id="left-corner"></div> <div id="middle-bar">About Us</div> <div id="right-corner"></div> These divs have corresponding images from CSS and are floated left. Those three divs create a single rounded button wiht text About Us which is fine. Problem: I have also created similar three slices of hover images but I wonder how to apply hover to those buttons because if I use :hover with these hovered slices, then even hovering on corner images also creates hovering effect. One alternative is to use fixed width buttons and slice buttons completely but I do not want to do that.

  • Colspan in IE7/8 not respected

    - by Stefan Kendall
    The DOM looks like this: <table> <tr> <td>a</td>...<td>g</td> </tr> <tr> <td colspan="3"> <table> ... </table> </td> </tr> <tr> <td></td>...<td></td> </tr> </table> Any idea why this wouldn't work in IE? I tried setting width:auto on the TD holding the inner table, and table-layout:fixed isn't viable because the tabular data is generated dynamically. What could be going wrong?

  • How would one use Cocos2d to create a game like this.

    - by John Stewart
    http://itunes.apple.com/us/app/angry-birds/id343200656?mt=8&ign-mpt=uo%3D6 So I am getting started with this all game dev thing on iphone and I decided that I will start playing with Cocos2d as my starting engine. Now just so i have a goal in mind, I picked angry birds as my initial target of what sort of game play would I like to learn to build. This is not going to be a market release game. This is totally going to be learning purposes only. So to start off my question is: Would something like this be achievable using Cocos2d? How would I go about building the physics for this? How can one do a screen scroll like the way they do in cocos2d? (any example code would be great) This is just to start off. If you have any particular questions please do add to this question.

  • How to simulate postback in nested usercontrols?

    - by jaloplo
    Hi all, I'm doing an asp.net application with one page. In this page, I have one usercontrol defined. This usercontrol has a menu (three buttons) and 3 usercontrols defined too. Depending on the clicked button one of the three usercontrols turn to visible true or false. In these three usercontrols I have a button and a message, and I want to show the message "It's NOT postback" when the button of the menu is clicked, and when the button of the usercontrol is clicked the message will be "YES, it's postback!!!". The question is that using property "IsPostBack" of the usercontrol or the page the message will never be "It's NOT postback" because of the clicked button of the menu to show the nested usercontrol. This is the structure of the page: page parent usercontrol menu nested usercontrol 1 message button nested usercontrol 2 nested usercontrol 3 I know it can be done using ViewState but, there is a way to simulate IsPostBack property or know when is the true usercontrol postback? Thanks.

  • How to share memory buffer across sessions in Django?

    - by afriza
    I want to have one party (or more) sends a stream of data via HTTP request(s). Other parties will be able to receive the same stream of data in almost real-time. The data stream should be accessible across sessions (according to access control list). How can I do this in Django? If possible I would like to avoid database access and use in memory buffer (along with some synchronization mechanism)

  • Google App Engine Python: get image upload size server-side

    - by goggin13
    I am building a Google App Engine App that lets users upload images; I have everything working fine, but I am struggling to find a way to ensure that the user does not upload an image too large (because I am resizing the images, so this crashes my python script). When a user uploads a large image, I get this error RequestTooLargeError: The request to API call images.Transform() was too large. I know that there is a size limitation on what GAE allows for it's image API, I am just trying to find a way to deal with this server side; something along the lines of if (image is too large): inform user else: proceed I haven't had any luck finding the right python code to do this; can anyone help me out?

  • Conceptual website designer ideas?

    - by Alex Tang
    Hi, I'm just wondering if anyone knows of any tool (apart from Visio) to generate visually nice looking website site maps or diagrams of a conceptual website. We're wanting to present some nice diagrams to our client but we're unsure about where to get started - we're all coders, not designers. Visio shapes or stencils are quite old. Just wondered what others in the industry are using!

  • What web server should I use if I want to run Java code behind it?

    - by Boaz
    At the moment, I have lot's of Java which does all kind of nifty stuff and I'm happy with it. The code is command line driven which have been great so far, but I recently decided I want to make the functionality available through web-services. Since my is complex and I'm happy with the way it's written , I don't want go through the pain of porting it to other languages. So I set out on a google journey to find out what web servers exist (on a Linux machine, though it's interesting to hear the answer without that limitation). From what I could find, it seems that there are two viable options: Apache Tomcat and Sun Java Server. What are the reason to choose one on top of the other? what are the strength of each and what are the weaknesses? Or, perhaps, there is a third one which is much easier, flexible and less cumbersome. Anyone?

  • What should be the considerations for choosing SQL/NoSQL?

    - by Yuval A
    Target application is a medium-sized website built to support several hundred-thousand users an hour, with an option to scale above that. Data model is rather simple, and caching potential is pretty high (~10:1 ratio of read to edit actions). What should be the considerations when coming to choose between a relational, SQL-based datastore to a NoSQL option (such as HBase and Cassandra)?

  • Help with Sharepoint (WSS 3.0) and JQuery

    - by Nicholas Selby
    Ok so the scenario is as follows: Have a sharepoint site setup on Microsoft Online, basically this site is a job booking system and is based on a custom sharepoint list. What I am trying to achieve is to extract List Items where the Invoiced Column is set to "No". Eventually I would like to post this to xero.com using their API as it accepts XML through the API Endpoints. Have tried using JQuery and JPoint but my limited programming skills are holding me back. Could anyone offer me some advice or point me in the right direction of someone that could help? am willing to pay someone if they can help me with getting this to work :)

  • Disabling Scrollbars in WebKit

    - by Aram Havarneanu
    Hello, I'm embedding WebKit in a Windows C++ Application. I'm using the Cairo port. It works fine. I'd like to disable the scrollbars that appear when there's more data that the client area can display. Like the iPhone, the iPhone does not have scrollbars, scrolling is implemented differently. How can I disable the scrollbars programatically, in C++ (no Javascript hacks)? Thanks,

  • Way to check files in and out with multiple developers.

    - by Roeland
    I am a web developer working with 2-3 people including me. Our current setup is very simplistic. We try to let each other know when we are working on a specific file. We use FTP to edit our files. Recently we have run into the problem of 2 people accidentally editing one file, or working on a local file then uploading when another person just did the same. From what I have read I need some sort of control system. I have heard of subversion and mercurial. It seems that these systems may not be what I need though, since its just giving me different versions of the files. I don't know if it solves the issue of two people working on a file and overwriting each others work. What are your suggestions for solving my problem?

  • Accurate Timings with Oscilloscopes on PC

    - by Paul Bullough
    In the world of embedded software (firmware) it is fairly common to observe the order of events, take timings and optimise a program by getting it to waggle PIO lines and capturing their behavior on an oscilloscope. In days gone by it was possible to toggle pins on the serial and parallel ports to achieve much the same thing on PC-based software. This made it possible to capture host PC-based software events and firmware events on the same trace and examine host software/firmware interactions. Now, my new laptop ... no serial or parallel ports! This is increasingly the case. So, does anyone have any suggestions as to go about emitting accurate timing signals off a "modern" PC? It strikes me that we don't have any immediately programmable, lag-free output pins left. The solution needs to run off a laptop, so using add-on cards that only plug into desktops are not permitted.

  • Ruby as a scripting language for web server

    - by Olivier Lalonde
    Is it possible to use Ruby as a scripting language with a HTTP server ? I'd like to be able to simply put some Ruby files in a web directory and be able to execute them from my browser - just like I did with PHP. I have absolutely nothing against frameworks such as RoR, but I was told that I should first learn Ruby and only then move on with higher level frameworks. Of course, I could write some Ruby scripts and run them in the console, but I would prefer getting the input/output from my browser :) Is that possible at all ? Otherwise, how hard would it be for me to build a quick and simple web framework ?

  • Modifying a model and texture mid-game code

    - by MicroPirate
    Just have a question for anyone out there who knows some sort of game engine pretty well. What I am trying to implement is some sort of script or code that will allow me to make a custom game character and textures mid-game. A few examples would be along the lines of changing facial expressions and body part positions in the game SecondLife. I don't really need a particular language, feel free to use your favorite, I'm just really looking for an example on how to go about this. Also I was wondering if there is anyway to combine textures for optimization; for example if i wanted to add a tattoo to a character midgame, is there any code that could combine his body texture and the tattoo texture into one texture to use (this way I can simply just render one texture per body.) Any tips would be appreciated, sorry if the question is a wee bit to vauge.

  • Horizontally align rows in multiple tables using web user control

    - by goku_da_master
    I need to align rows in different tables that are layed out horizontally. I'd prefer to put the html code in a single web user control so I can create as many instances of that control as I want and lay them out horizontally. The problem is, the text in the rows needs to wrap. So some rows may expand vertically and some may not (see the example below). When that happens, the rows in the other tables aren't aligned horizontally. I know I can accomplish all this by using a single table, but that would mean I'd have to duplicate the name, address and phone html code instead of dynamically creating new instances of my user control (in reality there are many more fields than this, but I'm keeping it simple). Is there any way to do this whether with div's, tables or something else? Here's the problem: Mary Jane's address field expands 2 lines, causing her phone field to not align properly with John's and Bob's. Name: John Doe Name: Mary Jane Name: Bob Smith Address: 123 broadway Address: Some really long address Address: Short address Phone: 123-456 that takes up multiple lines Phone: 111-2222 Phone: 456-789 I'm not restricted in any way how to do this (other than using asp.net), but I'd prefer to use a single web control that I instantiate X times at design time (in this example, it's 3 times). I'm using VS2008, and .Net 3.5

  • JQuery Help: toggle() is not working properly

    - by John Smith
    Hi All, I'm trying to use JQuery toggle functionality, but not able to use properly. Instead of smooth slide up and down, it goes very fast and not in an animated manner. I want to achieve sliding effect in my code, like this has (Please see Website Design, Redesign Services slider): Here is my code: HTML: <div> <div class="jquery_inner_mid"> <div class="main_heading"> <a href="#"> <img src="features.jpg" alt="" title="" border="0" /></a> </div> <div class="plus_sign"> <img id="imgFeaturesEx" src="images/plus.jpg" alt="" title="" border="0" /> <img id="imgFeaturesCol" src="images/minus.jpg" alt="" title="" border="0" /></div> <div class="toggle_container"> <div id="divMain" > </div> </div> </div> <div class="jquery_inner_mid"> <div class="main_heading"> <img src="About.jpg" alt="" title="" /></div> <div class="plus_sign"> <img id="imgTechnoEx" src="images/plus.jpg" alt="" title="" border="0" /> <img id="imgTechnoCol" src="images/minus.jpg" alt="" title="" border="0" /></div> <div class="toggle_container"> <div id="divTechnossus" > </div> </div> </div> </div> JQuery: $(function() { document.getElementById('imgFeaturesCol').style.display = 'none'; document.getElementById('imgTechnoCol').style.display = 'none'; $('#imgFeaturesEx').click(function() { $.getJSON("/Visitor/GetFeatureInfo", null, function(strInfo) { document.getElementById('divMain').innerHTML = strInfo; }); $("#divMain").toggle("slow"); document.getElementById('imgFeaturesEx').style.display = 'none'; document.getElementById('imgFeaturesCol').style.display = 'block'; }); $('#imgFeaturesCol').click(function() { document.getElementById('divMain').innerHTML = ""; $("#divMain").toggle("slow"); document.getElementById('imgFeaturesCol').style.display = 'none'; document.getElementById('imgFeaturesEx').style.display = 'block'; }); $('#imgTechnoEx').click(function() { $.getJSON("/Visitor/GetTechnossusInfo", null, function(strInfo) { document.getElementById('divTechnossus').innerHTML = strInfo; }); $("#divTechnossus").slideToggle("slow"); document.getElementById('imgTechnoEx').style.display = 'none'; document.getElementById('imgTechnoCol').style.display = 'block'; }); $('#imgTechnoCol').click(function() { document.getElementById('divTechnossus').innerHTML = ""; $("#divTechnossus").slideToggle("slow"); document.getElementById('imgTechnoCol').style.display = 'none'; document.getElementById('imgTechnoEx').style.display = 'block'; }); });
