    memory leak with setInterval

    This is a real showtopper. My application needs to run for hours at a time without resetting, using limited processing cycles and limited memory. It uses Ajax to poll the server every few seconds. Unfortunately, the setInterval to used to make the poll tick over is leaking. I'm running a...

    'kill script' feature HTML5

    According to w3c, HTML5 has this feature where one can set parameters to have JS kill a script if certain conditions are met. Here's the ref: http://dev.w3.org/html5/spec/webappapis.html#killing-scripts Is this a feature *new* in HTML5? i.e. it was not doable before? If so, how? I haven't...

    SVG document format vs HTML

    I could not find a more appropriate sub forum for this. I always thought SVG was specifically an image format; it seems it is more generally a document format. So I've been given an SVG page (i.e. there is no SVG element embedded in an HTML page, this SVG page stands on its own and renders...

    basic JSP/XML error - Unable to find a value for "x" in object of cla

    Having trouble zeroing in on this bug. I'm pretty new to struts and XML. I'm just debugging the code, so I didn't build this. Other pages work great, so not a system problem. javax.servlet.jsp.JspException: An error occurred while evaluating custom action attribute "value" with value...

    How to Set up Struts on my system

    I've got to learn Struts - and quickly. I've got a tutorial (Struts Design and Programming) but it seems to assume my system is all set up. So I need to get my laptop set up to develop in Java 1.2 SDK I believe? Can someone give me a shove towards appropriate downloads and instructions for this?

    What CMS is good for user-defined metadata?

    I'm looking on opensourcecms.com but frankly, it's just TOO big. I'm looking for a CMS that supports (preferably by default rather than development) many user fields for metadata. Think of sites that might track things like weather observations or personals or logs for divers/hikers/athletes...

    scrolling div height = browser window height

    I want to make a div whose content scrolls vertically, using overflow-y:scroll. But I want the div to fill the browser window top to bottom regardless of what height the browser is, such as a low screen rez i.e. div height=100% This doesn't work - since the content is very large, the dive...

    I want to play mp3s and flvs in Flash called from external files by way of XML. Could someone give me a shove in the right direction?

    browser causing problem w/ invisible divs?

    I have been having trouble with a certain website, but thought it was their problem until I found a second site causing a possibly related problem. Now I'm wondering if it's my browser. I'm running IE6.0.2900.2180.xpsp_sp2 on XP. This is the site I was originally having trouble with...

    looking for web-based user comment engine

    I'm looking for an engine to form the core of my website. The website will have a database that users fill with comments etc. and are searchable by lots of metadata. It's not a blog, as I do not provide the content, the users do. Let me see if I can propose a hypothetical example: Say it's a...

    div sizing

    This is easy-peasy with tables, but I don't know how to do it with DIVs: 1] I have a div nested inside another div. The inner div is position: absolute; right: 20px. Problem is, my inner div is *taller* than my outer div *wants* to be - the inner div hangs off the bottom edge of the outerdiv...

    more CSS alignment

    Also, do DIVs have the equivalent of tablecell width "*"? i.e. I want the outer div to be 100%, the inner RIGHT div to have a fixed width, and the inner LEFT div to be variable in width.

    CSS div alignment

    Maybe this is the right forum... I have a div nested inside another div. The inner div is position: absolute; right: 20px. Problem is, my inner div is *taller* than my outer div *wants* to be - the inner div hangs off the bottom edge of the outerdiv. How can I get my outer div to expand to...

    large strings of chars in URLs

    What purpose do these large values serve? default.asp?4YINDs4an1nFScVSPL34dK$kdx31Rh7oZl$NW8ySOgdICYuKQMfi6EcVhgaWqc_w I presume it's some sort of security encryption. Are these half of a public key?

    testing for $_SESSION variable w/ isset

    I want to ensure that, when I first come into the script I know or set the value of variable 'debug'. I first need to know if it's set. if (isset($_SESSION['debug'])){ $debug=$_SESSION['debug']; } else{ $debug=0; } This gives me a warning on the first line: Notice: Undefined index: debug

    PHP error message switch

    I'm developing PHP on my Webhost, but I'm not getting any messages back when there are errors, I just get blank pages. I know there's a setting that displays error messages in my browser. Tech Support told me to do this: error_reporting(E_ALL) but that's not doing the trick (I use this setting...
