  • Do most web 'programmers' (not designers) use WYSIWYG editors or hand code their HTML?

    - by John MacIntyre
    When I started programming web pages, it became immediately obvious that the WYSIWYG editors sucked. The HTML output was difficult to maintain, did things in ways you may not have agreed with, completely messed up existing pages if opened, couldn't handle code in the page, and was polluted with dead or irrelevant code like <font ...></font>. At that time, I didn't know a single programmer with more than 6 months experience who didn't hand code their HTML. Even now, most of the developers I know hand code their HTML. But, I also realize this was a decade ago, WYSIWYG editors have improved, and I may be seriously underproductive hand coding my HTML. Do you, as a web programmer, use WYSIWYG editors for your HTML? PS-I'm kind of thinking we can just vote either YES or NO, and put comments below.

  • Working with three dimensional data in an HTML (ASP.NET) table.

    - by ProfK
    I am working on the prototype for a scheduling application on an intranet system. The application is for scheduling and tracking promotional workers at various locations on various dates (hence location, date, workers dimensions). Currently, only for prototyping, I am generating a data table of location/date, and from this I iteratively build an HTML table (asp:Table control). On visiting each cell, I query for people working that location-date and populate the cell accordingly. This is very inefficiant, and will at worst be improved by querying cached data for the whole location/date grid. I'm looking around for established patterns and techniques for dealing with scenarios like this in HTML in general, maybe a visualisation library for jQuery or something, and for ASP.NET in particular, maybe a library for implementation on a GridView etc. Am I going in the right direction with this, and if so, what recomendations are there regarding the previous paragraph?

  • What are some affordable developer resources?

    - by ritu
    Hi Guys (and gals), In the past my employers bought me subscriptions to MSDN and Safari but now that I am working as a contractor and have to pay for these things myself, I was wondering if there are other services that offer subscriptions or access to technical books. I develop on Windows using C++ and .NET.

  • Need to dynamically-generate a "sticky note" text

    - by gravyface
    Working on a website that has an image of a sticky note which will change text somewhat frequently (every month or so) as new "todo" items are created on it. Font I'm currently using is not Web Safe and the text is slightly angled to match the skew of the sticky note as well. Now I'm a pragmatist, and in situations like this I would normally secede defeat and opt for something more CSS/HTML practical. But no more! I'm falling a bit behind on what's going on with HTML5, CSS3, PNG graphics, Flash (ugh), and/or any other rich visuals. I'm decent with PHP/CSS/JS (jquery), have dabbled in Flash/actionscript too. My question is: what tools/method should I be looking at here?

  • problem with a very simple tile based game

    - by newbieguy
    Hello, I am trying to create a pacman-like game. I have an array that looks like this: array: 1111111111111 1000000000001 1111110111111 1000000000001 1111111111111 1 = Wall, 0 = Empty space I use this array to draw tiles that are 16x16 in size. The Game character is 32x32. Initially I represented the character's position in array indexes, [1,1] etc. I would update his position if array[character.new_y][charater.new_x] == 0 Then I translated these array coordinates to pixels, [y*16, x*16] to draw him. He was lining up nicely, wouldn't go into walls, but I noticed that since I was updating him by 16 pixels each, he was moving very fast. I decided to do it in reverse, to store the game character's position in pixels instead, so that he could use less than 16 pixels per move. I thought that a simple if statement such as this: if array[(character.new_pixel_y)/16][(character.new_pixel_x)/16] == 0 would prevent him from going into walls, but unfortunately he eats a bit of the bottom and right side walls. Any ideas how would I properly translate pixel position to the array indexes? I guess this is something simple, but I really can't figure it out :(

  • Visual Studio Stop Debugging on IE Close - WebSite?

    - by Mark
    Hi all, Would like to know if there is a setting anywhere which causes debugging to automatically stop when IE closes, and also if there is a way for this to work the other way around and IE to close if debugging stops. I know that this works when the project type I'm working on is a 'Web Application', I'd like to know if the same functionality exists when working on a 'Web Site' Thanks all.

  • What's the "correct way" to organize this project?

    - by user571747
    I'm working on a project that allows multiple users to submit large data files and perform operations on them. The "backend" which performs these operations is written in Perl while the "frontend" uses PHP to load HTML template files and determines which content to deliver. Data is stored in a database (MySQL, SQLite, Oracle) and while there is data which has not yet been acted upon, Perl adds it to a running queue which delivers data to other threads based on system load. In addition, there may be pre- and post-processing of the data before and after the main Perl script operates (the specifications are unclear) so I may want to allow these processors to be user-selectable plugins. I had been writing this project in a more procedural fashion but I am quickly realizing the benefit of separating concerns as to limit the scope one change has on the rest of the project. I'm quite unexperienced with design patterns and am curious what the best way to proceed is. I've heard MVC thrown around quite a bit but I am unsure of how to apply it. Specifically, what are some good options to structure this code (in terms of design patterns and folder hierarchy)? How can I achieve this with both PHP and Perl while minimizing duplicated code between languages? Should I keep my PHP files in the top level so I don't have ugly paths in the URL? Also, if I want to provide interchangeable databases, does each table need its own DAO implementation?

  • C/PHP: How do I convert the following PHP JSON API script into a C plugin for apache?

    - by TeddyB
    I have a JSON API that I need to provide super fast access to my data through. The JSON API makes a simply query against the database based on the GET parameters provided. I've already optimized my database, so please don't recommend that as an answer. I'm using PHP-APC, which helps PHP by saving the bytecode, BUT - for a JSON API that is being called literally dozens of times per second (as indicated by my logs), I need to reduce the massive RAM consumption PHP is consuming ... as well as rewrite my JSON API in a language that execute much faster than PHP. My code is below. As you can see, is fairly straight forward. <?php define(ALLOWED_HTTP_REFERER, 'example.com'); if ( stristr($_SERVER['HTTP_REFERER'], ALLOWED_HTTP_REFERER) ) { try { $conn_str = DB . ':host=' . DB_HOST . ';dbname=' . DB_NAME; $dbh = new PDO($conn_str, DB_USERNAME, DB_PASSWORD); $params = array(); $sql = 'SELECT homes.home_id, address, city, state, zip FROM homes WHERE homes.display_status = true AND homes.geolat BETWEEN :geolatLowBound AND :geolatHighBound AND homes.geolng BETWEEN :geolngLowBound AND :geolngHighBound'; $params[':geolatLowBound'] = $_GET['geolatLowBound']; $params[':geolatHighBound'] = $_GET['geolatHighBound']; $params[':geolngLowBound'] =$_GET['geolngLowBound']; $params[':geolngHighBound'] = $_GET['geolngHighBound']; if ( isset($_GET['min_price']) && isset($_GET['max_price']) ) { $sql = $sql . ' AND homes.price BETWEEN :min_price AND :max_price '; $params[':min_price'] = $_GET['min_price']; $params[':max_price'] = $_GET['max_price']; } if ( isset($_GET['min_beds']) && isset($_GET['max_beds']) ) { $sql = $sql . ' AND homes.num_of_beds BETWEEN :min_beds AND :max_beds '; $params['min_beds'] = $_GET['min_beds']; $params['max_beds'] = $_GET['max_beds']; } if ( isset($_GET['min_sqft']) && isset($_GET['max_sqft']) ) { $sql = $sql . ' AND homes.sqft BETWEEN :min_sqft AND :max_sqft '; $params['min_sqft'] = $_GET['min_sqft']; $params['max_sqft'] = $_GET['max_sqft']; } $stmt = $dbh->prepare($sql); $stmt->execute($params); $result_set = $stmt->fetchAll(PDO::FETCH_ASSOC); /* output a JSON representation of the home listing data retrieved */ ob_start("ob_gzhandler"); // compress the output header('Content-type: text/javascript'); print "{'homes' : "; array_walk_recursive($result_set, "cleanOutputFromXSS"); print json_encode( $result_set ); print '}'; $dbh = null; } catch (PDOException $e) { die('Unable to retreive home listing information'); } } function cleanOutputFromXSS(&$value) { $value = htmlspecialchars($value, ENT_QUOTES, 'UTF-8'); } ?> How would I begin converting this PHP code over to C, since C is both better on memory management (since you do it yourself) and much, much faster to execute?

  • PHP: prepared statement, IF statement help needed

    - by JGreig
    I have the following code: $sql = "SELECT name, address, city FROM tableA, tableB WHERE tableA.id = tableB.id"; if (isset($price) ) { $sql = $sql . ' AND price = :price '; } if (isset($sqft) ) { $sql = $sql . ' AND sqft >= :sqft '; } if (isset($bedrooms) ) { $sql = $sql . ' AND bedrooms >= :bedrooms '; } $stmt = $dbh->prepare($sql); if (isset($price) ) { $stmt->bindParam(':price', $price); } if (isset($sqft) ) { $stmt->bindParam(':price', $price); } if (isset($bedrooms) ) { $stmt->bindParam(':bedrooms', $bedrooms); } $stmt->execute(); $result_set = $stmt->fetchAll(PDO::FETCH_ASSOC); What I notice is the redundant multiple IF statements I have. Question: is there any way to clean up my code so that I don't have these multiple IF statements for prepared statements?

  • How to check if aspect ratio auto adjustment is enabled in monitor

    - by kFk
    Game application is written in C++ and uses DirectX 8. I am getting a maximum monitor resolution to calculate it's aspect ratio. Then I use this value to fix game rendering (scale and set clipping to receive normal 4:3 image with black borders on wide screen monitors). How can I check if monitor is using aspect ratio auto adjustment now? Because my scaling plus monitor scaling makes resulting image overscaled. Thanks EDIT: I saw correct different monitor resolution handling with or without aspect ratio auto adjustment in "Royal Envoy" casual game. But don't know how do they do this.

  • jQuery: what is it "forbidden" to do in plain Javascript

    - by flybywire
    A jQuery best practices question. I am writing a very jQuery intensive web page. I am new to jQuery and notice its power, but as I come with heavy javascript experience and knowledge, my question is: What should be done in jQuery and what in plain javascript. For example, there are callbacks that send a plain DOM object as an argument. Should I use that or should I wrap it ( like $(this)). Does it matter if I do this.x=y or $(this).attr("x", y).

  • Business web application platform structure

    - by VoodooRider
    Hi, I would like to develop a web application in java/spring/hibernate serving as a business platform that I could connect plugins to (i.e. CRM plugin, ware plugin, sales plugin). Those plugins could be dependent of other plugins in a tree manner. The parent project would be packaged as war having all the basic configuration and looks (spring configs, css, scripts), ready to go user and group management, security settings, etc. All together I would like it to behave and look a bit like Joomla, but built using different tools for different purposes. And I have a few questions concerning that project: Do you know of any open source projects offering such a platform ready to go? If not is maven applicable for managing those plugins? What is the best way to package and deploy those plugins? And the last but not least, basically is this the right way to go or is a dead end and it would be better to create a separate web app for those business needs?

  • Hidden links are still clickable on the Android browser

    - by David
    I've got a contextual menu that appears when a button is clicked. This menu has some links and after some seconds is hidden again. The problem is that after the menu has disappeared the links are still there. They are not shown but are clickable and the green border appears. And after some seconds they disappear. I've tryied many ways of hiding the menu: display: none, visibility: hidden, width: 0, height: 0, jquery hide, jquery fadeout... but none worked. Also hidding the links. Does anyone have a idea about what's happening? With the rest of the browsers it works without problem Thanks

  • Why does placing this html within form tags change the layout?

    - by user352687
    I'm using this free Web Template - EliteCircle and have just incorporated it into a master page. The master page wraps the html in: <form id="form1" runat="server"> //master page html </form> The template almost comes out fine except the entire page is surrounded by a think white border (default CSS behavior for form?) and the footer background is half white on the very bottom. I wouldn't expect the form with id=form1 to change anything in the layout. There is nothing in the [CSS][2] with that id. When I remove the form tags from the master page (just to check) the layout is perfect, no problems. Any ideas? (Using Visual Web Developer 2008 Express) Thanks, Greg The CSS: http://www.styleshout.com/templates/preview/EliteCircle12/images/EliteCircle.css

  • Using code from this site

    - by user553798
    Hi, The legal section of this site mentions that all code by the contributors is licensed under the Creative Commons Attribution Share Alike License. Does this mean that I have to attribute the submitter even if the code in question is a few lines amongst hundreds or thousands of lines of code? What if I use code from a book or SDK? For eg; If I use the sample code from Google's Android SDK documentation, does that mean I need to attribute Google every time I write an app, after all it would be impossible to write an app without consulting the SDK docs, atleast initially... I am totally confused :S

Is there a way to fix this without resorting to Javascript?
