  • IE image map remains clickable behind another div

    - by Ryan Giglio
    I have an Image Map of the United States. When you click on a state, the map fades out and a map of that state appears with an image map of the area codes in the state. In Firefox, Safari, and Chrome, the state map becomes clickable and the United States map becomes unclickable until you close the sate popover. However in Internet Explorer, the United States map remains clickable through the state popover, and I cannot click on any area codes. Here is my javascript: $(document).ready(function() { $("#usMap").html(); $("#usMap").load("/includes/us_map.inc"); }); $('area').live('click', function() { var state = $(this).attr("class"); var statePopover = $("<div id='statePopoverContainer'><a id='popoverCloseButton'>Close State</a><div id='statePopover'></div></div>"); $("#usMap").append(statePopover); $("#usMapImage").fadeTo('slow', 0.2); $("#statePopover").load("/includes/stateMaps/" + state + ".html"); }); $("#popoverCloseButton").live('click', function() { $("#statePopoverContainer").remove(); $("#usMapImage").fadeTo('slow', 1); }); I am loading the map on document ready because if you don't have Javascript, something else appears. And here is the CSS for all things related: div#usMap { width:676px; height:419px; text-align: center; position: relative; background-color:#333333; z-index: 1; } img#usMapImage { z-index: 1; } area { cursor: pointer; } div#statePopoverContainer { width:100%; height:100%; z-index:5; position:absolute; top:0; left:0; } a#popoverCloseButton { position:absolute; right:0; padding-right:5px; padding-top:5px; color:#FFFFFF; cursor:pointer; } You can see this happening at http://dev.crewinyourcode.com/ Login with beta/tester

  • Basic concepts in file system implementation

    - by darkie15
    I am a unclear about file system implementation. Specifically (Operating Systems - Tannenbaum (Edition 3), Page 275) states "The first word of each block is used as a pointer to the next one. The rest of block is data". Can anyone please explain to me the hierarchy of the division here? Like, each disk partition contains blocks, blocks contain words, and so on...

  • Is there any reasonable use of a function returning an anonymous struct?

    - by Akanksh
    Here is an (artificial) example of using a function that returns an anonymous struct and does "something" useful: #include <iostream> template<typename T> T* func( T* t, float a, float b ) { if(!t) { t = new T; t->a = a; t->b = b; } else { t->a += a; t->b += b; } return t; } struct { float a, b; }* foo(float a, float b) { if(a==0) return 0; return func(foo(a-1,b), a, b); } int main() { std::cout << foo(5,6)->a << std::endl; std::cout << foo(5,6)->b << std::endl; void* v = (void*)(foo(5,6)); float* f = (float*)(v); //[1] delete f now because I know struct is floats only. std::cout << f[0] << std::endl; std::cout << f[1] << std::endl; delete[] f; return 0; } There are a few points I would like to discuss: As is apparent, this code leaks, is there anyway I can NOT leak without knowing what the underlying struct definition is? see Comment [1]. I have to return a pointer to an anonymous struct so I can create an instance of the object within the templatized function func, can I do something similar without returning a pointer? I guess the most important, is there ANY (real-world) use for this at all? As the example given above leaks and is admittedly contrived. By the way, what the function foo(a,b) does is, to return a struct containing two numbers, the sum of all numbers from 1 to a and the product of a and b. EDIT: Maybe the line new T could use a boost::shared_ptr somehow to avoid leaks, but I haven't tried that. Would that work?

  • Examples of attoparsec in parsing binary file formats?

    - by me2
    Previously attoparsec was suggested to me for parsing complex binary file formats. While I can find examples of attoparsec parsing HTTP, which is essentially text based, I cannot find an example parsing actual binary, for example, a TCP packet, or image file, or mp3. Can someone post some code or pointer to some code which does this using attoparsec?

  • Java mouse motion anywhere on screen

    - by Dave
    I'm sure this is possible but all my searching is coming up blank. In Java is it possible to register for a mouse motion event outside of a Java app? So if the mouse pointer moves anywhere on the screen I get a call back. An approximation is possible with polling MouseInfo.getPointerInfo but there must be a better way. Thanks

  • Is it possible to build a WinForm app (or another type of .NET app) which allows me to interact with

    - by RoboShop
    I'm learning Chinese at the moment and I have gotten my hand on a Chinese dictionary definition. Now I would like to make an interface. All I really want the application to do is when I point my mouse pointer over any text on the screen (in any window), it would identify the text I am pointing at and then display a small form over it, which would the chinese transaction. Is that possible to do? Can WinForms apps interact with windows outside of it's own application?

  • How to handle an array of pointers in Objective-C

    - by DougW
    I figured out the answer to this question, but I couldn't find the solution on here, so posting it for posterity. So, in Objective-C, how do you create an object out of a pointer in order to store it in objective-c collections (NSArray, NSDictionary, NSSet, etc) without reverting to regular C?

  • No middle-click scrolling in visual studio 2010?

    - by maxp
    Just as I started to assume this feature was ubiquitous(middle-clicking on a page, then scrolling speed/direction is relative to the distance of the pointer on the y-axis). I can't believe this hasn't been implemented into the text editor in vs2010, I used it all the time in 2005 and 2008. Has anyone managed to find a workaround or am I a minority user of this feature?

  • jQuery: List expands on page load

    - by Hasanah
    I've been looking for something very simple: How to make a side navigation expand with animation on page load, but all the tutorial websites I usually go to don't seem to have it. The closest I could find is this jQuery sample: http://codeblitz.wordpress.com/2009/04/15/jquery-animated-collapsible-list/ I've managed to strip down the list like so: <script type="text/javascript" src="jquery-1.3.2.min.js"></script> <script type="text/javascript"> $(function(){ $('li') .css('pointer','default') .css('list-style','none'); $('li:has(ul)') .click(function(event){ if (this == event.target) { $(this).css('list-style', (!$(this).children().is(':hidden')) ? 'none' : 'none'); $(this).children().toggle('slow'); } return false; }) .css({cursor:'pointer', 'list-style':'none'}) .children().hide(); $('li:not(:has(ul))').css({cursor:'default', 'list-style':'none'}); }); <body> <fieldset> <legend>Collapsable List Demo</legend> <ul> <li>A - F</li> <li>G - M <ul> <li>George Kent Technology Centre</li> <li>Hampshire Park</li> <li>George Kent Technology Centre</li> <li>Hampshire Park</li> </ul> </li> <li> N - R </li> <li>S - Z</li> </ul> </fieldset> My question is: Is there any way to make this list expand on page load instead of on click? I also don't need it to collapse at all; basically I need only the animating expansion. Thank you for your time and advice. :)

  • Returning a shared library symbol table

    - by joemoe
    For instance: void* sdl_library = dlopen("libSDL.so", RTLD_LAZY); void* initializer = dlsym(sdl_library,"SDL_Init"); Assuming no errors, initializer will point to the function SD_Init in the shared library libSDK.so. However this requires knowing the symbol "SDL_Init" exists. Is it possibly to query a library for all its symbols? Eg, in this case it would return SDL_Init, the function pointer, and any other symbols exported by libSDL.so.
