  • How to reset persistent scrollbar position after div refresh in FF3?

    - by rcon
    Hi, I'm experiencing a weird scrollbar issue. I'm building a page that uses jQuery and PHP to dynamically load images into a DIV sequentially. This DIV is a fixed height but uses a scrollbar for its variable width. The problem is that the scrollbar does not reset after a dynamic refresh of the DIV. So when the user scrolls and then refreshes with new content, the scroll bar position stays persistent instead of resetting back to the left. This seems to only happen in FF3. The scrollbar resets perfectly fine in Chrome, Safari, and IE8. For each refresh, the DIV is hidden, emptied, sized with CSS, then sequentially appended with images. I've tried resetting white-space: normal before the nowrap, playing around with overflow, and also jQuery's scrollLeft to no avail. It still behaves strangely in FF3, and only FF3. http://www.shadowshapes.com/uttdev/ Click a thumbnail, move the scrollbar then click another thumb. Thanks for any help!

  • Create set of random JPGs

    - by Kylar
    Here's the scenario, I want to create a set of random, small jpg's - anywhere between 50 bytes and 8k in size - the actual visual content of the jpeg is irrelevant as long as they're valid. I need to generate a thousand or so, and they all have to be unique - even if they're only different by a single pixel. Can I just write a jpeg header/footer and some random bytes in there? I'm not able to use existing photos or sets of photos from the web. The second issue is that the set of images has to be different for each run of the program. I'd prefer to do this in python, as the wrapping scripts are in Python. I've looked for python code to generate jpg's from scratch, and didn't find anything, so pointers to libraries are just as good.

  • PHP GD issues with ImageCreateTrueColor and PNGs

    - by DrPheltRight
    I am resizing PNG images using the GD image library function ImageCopyResampled(). It all works fine, I can even keep alpha blending transparency with the use of ImageCreateTrueColor() rather than using ImageCreate() to create the resized image. The problem is, that if I use ImageCreateTrueColor() rather than ImageCreate() the file size of PNG files increases from something like 80kb to 150kb. If I use ImageCreate() the file size stays around the same size, but colors screw! So my question is, how can I retain alpha blending when resizing PNG images without increasing the file size? Oh and I am reducing the dimensions of the PNGs.

  • How do you pass objects between View Controllers in Objective-C?

    - by editor
    I've been trudging through some code for two days trying to figure out why I couldn't fetch a global NSMutableArray variable I declared in the .h and implemented in .m and set in a the viewDidLoad function. It finally dawned on me: there's no such thing as a global variable in Objective-C, at least not in the PHP sense I've come to know. I didn't ever really read the XCode error warnings, but there it was, even if not quite plain English: "Instance variable 'blah' accessed in class method." My question: What am I supposed to do now? I've got two View Controllers that need to access a central NSMutableDictionary I generate from a JSON file via URL. It's basically an extended menu for all my Table View drill downs, and I'd like to have couple other "global" (non-static) variables. Do I have to grab the JSON each time I want to generate this NSMutableDictionary or is there some way to set it once and access it from various classes via #import? Do I have to write data to a file, or is there another way people usually do this?

  • IE is doing strange things with JQuery

    - by Syncopated
    So ... The thing is, the code works in FireFox, no problems. But when I open the same page, it gives me the following error: "Undefined is null or not an object." But when I copy the code to a localhost page, it works fine. Also when I clear my cache in IE it works, but only once, if I refresh after that one load, it gives me the same error. Here is the code: <script type="text/javascript" src="datepicker/js/jquery-1.4.2.min.js"></script> <script type="text/javascript"> var count3 = 0; var count5 = 0; var count2 = 0; var count4 = 0; $(document).ready(function(){ $('#switch3').click(function(){ $('#switchDiv3').slideToggle(350); if(count3 == 0){ count3 = 1; document.getElementById('switchImage3').src = "images/ArrowDown.png"; return; } else { count3 = 0; document.getElementById('switchImage3').src = "images/ArrowRight.png"; return; } }); ... (this is the code for each item that is generated) </script> And the code that determines the div that should hide: <table width="100%" border="0" cellspacing="0" cellpadding="0" align="center"> <tr> <td width="20" align="center" valign="top" style="padding-right: 3px"> <a style="cursor: pointer;" id="switch3"><img width="20" height="20" src="images/ArrowRight.png" id="switchImage3" style="border-style: solid; border-width: 1px; border-color: black;"/></a> </td> <td> <div id="switchDiv3"> <div align="left"> (Contents of the div here) </div> </div> </td> </tr> </table> Any help is appreciated! Thanks in advance

  • I can't click the links in Firefox and Chrome (they work in IE7)

    - by janoChen
    Its the weirdest thing I've ever seen. I can't click the last 3 links in the following code (when I use FF or Chrome): HTML: <div id="leftmanulist"> <div class="abouttop"> <ul class="aboutlist"> <li class="index"><a>????</a></li> <li><a href="instruments.html">????</a></li> <li><a href="performance.html">????</a></li> <li><a href="clothes.html">????</a></li> <li><a href="aboutfalundafa.html">??????</a></li> <li><a href="awards.html">????</a></li> </ul> </div> <div class="aboutbutton"></div> </div> CSS: #leftmanulist{ background:url("images/abouttop.gif") no-repeat; float: left; margin: 2px 2px 5px 30px; padding:39px 0 0 0; width:237px;} #leftmanulist ul li{line-height:35px;text-align:left; text-decoration:none;} #leftmanulist ul li a{ text-decoration:none;} #leftmanulist ul li:hover{ color:#0068FF;} #leftmanulist ul li a:hover{ color:#0068FF;} #leftmanulist ul li.index{ color:#0068FF;} #leftmanulist ul li.index a{ color:#0068FF;} .abouttop{background:url("images/leftmanulist_z.gif") repeat-y ; padding:0 6px; position:relative; z-index:0; width:237px;} .aboutlist{position:relative;left:28px;} .aboutbutton{background:url("images/leftmanulist_b.gif") no-repeat; width:237px; height:20px; position:relative; top:-17px; z-index:2;}

  • Are there any good Javascript/Jquery thumbnail script equivalents to TimThimb (PHP)?

    - by Mark
    For those unaware of TimThumb, it will take any image, of any size or dimension and create a thumbnail on the fly to any desired size. The beauty of it is that it really works on any dimension you feed it through a combination of either resizing the image, cropping or zoom cropping the image. Ive been searching for jscript equvalents but they either require the user to actually mask out the thumbs manually (looking for a script that automatically does it to images) or the scripts can't handle images in a different aspect ratio. Thanks for any leads on this!

  • Is it a good idea to include a large text variable in compiled code?

    - by gladman
    I am writing a program that produces a formatted file for the user, but it's not only producing the formatted file, it does more. I want to distribute a single binary to the end user and when the user runs the program, it will generate the xml file for the user with appropriate data. In order to achieve this, I want to give the file contents to a char array variable that is compiled in code. When the user runs the program, I will write out the char file to generate an xml file for the user. char* buffers = "a xml format file contents, \ this represent many block text \ from a file,..."; I have two questions. Q1. Do you have any other ideas for how to compile my file contents into binary, i.e, distribute as one binary file. Q2. Is this even a good idea as I described above?

  • Show different product image in new.phtml vs. list

    - by user1907662
    $collection = $this->_addProductAttributesAndPrices($collection) ->addStoreFilter() ->addAttributeToFilter('is_discontinued', array('neq' => 1) ) ->addAttributeToFilter('collection_id', array('neq' => 'LKG') ) ->addAttributeToFilter('media_gallery_label', array('eq' => 'Home Page Image') ) //->addAttributeToSort('entity_id', 'desc') ->addAttributeToSort('news_from_date', 'desc') For the media_gallery_label field, I need to be able to filter by any gallery images, and if the label of any of the images is "Home Page Image", it needs to display instead of the default "small" image. I need this to work only in new.phtml file, and not in the list.phtml.

  • How to achieve jQuery scrolling/overlay effect (video in description)

    - by waffl
    I have two columns. The left column contains text of dynamic lengths. The right column is of fixed height and will contain a set of images selected at random per page load. I am trying to create an effect where while the user scrolls, the Image 2 scrolls above Image 1. When it reaches the top, the Image 1 begins to scroll up until it disappears, then Image 3 comes in and repeats the process. As this is rather confusing, I made a short video describing the desired effect. Video - MP4 I have begun trying to get it working in this jsbin but am at a loss for when the user scrolls back down and also when more images are required. I am thinking my current path is not the right direction. I'm thinking that employing something like jQuery waypoints is more the direction I should be pursuing?

  • IE7 cutting off image

    - by Kimberley
    Hi all I have 3 divs with rollover images inside them stacked vertically inside my main content div. IE7 is chopping off about three quarters of the bottom div and I can't figure out why. It displays perfectly in all other browsers (even IE6) but IE7 just won't display properly. This is my first website so I still have a lot to learn. I've managed to fix the other IE bugs but just can't figure this one out. Any help appreciated! } .main_content { float: left; width: 816px; background-image: url(Images/evokedesign_bg_tile.png); background-repeat: repeat-y; overflow: hidden; } .portfolio_buttons { float: left; width: 634px;

  • How to detect if an element exists in Watir

    - by Rijksband
    Hi, I'm relatively new to Watir but can find no good documentation (examples) regarding how to check if an element exists. There are the API specs, of course, but these make precious little sense to me if I don't find an example. I've tried both combinations but nothing seems to work... if browser.image (:src "/media/images/icons/reviewertools/editreview.jpg").exists then... if browser.image (:src "/media/images/icons/reviewertools/editreview.jpg").exists? then... If anyone has a concrete suggestion as per how to implement this, please help! Thanks!

  • Online image resizer

    - by Happy
    Searching for some script or service for online image resizing. I should have the ability to throw my imagelink, like http://site.com/bigimage.jpg, and it must give me this image after resizing like http://site-were-image-resized.com/sdf4234f21f.png. It would be amazing, if I can give some values, like height and width. If I upload script on my own site, it should have the ability to resize external images from some domains. Tryed to use http://www.darrenhoyt.com/demo/timthumb/, but it doesn't work with external images.

  • Macro C++ Issues __VA_ARGS__

    - by CodeLizard
    What (if any) are some potential problems with a C++ macro usage like this? Would an inline function be a more appropriate solution? #define EVENT_INFO(_format_, ...) CMyEvent::Generate(__FILE__, __LINE__, CMyEvent::EVT_HIGH, _format_, __VA_ARGS__) void CMyEvent::Generate( const char* file, // filename int line, // line number CMyEvent::LEVEL level, // severity level const char *format, // format of the msg / data ...) // variable arguments { // Get a message from the pool CMyEvent* p_msg = GetMessageFromPool(); if(p_msg != NULL) { va_list arguments; // points to each unnamed argument va_start(arguments, format); // Fill the object with strings and data. p_msg->Fill(file, line, level, 0, format, arguments); va_end(arguments); } }

  • What code commenting style should I use for both C++ and C# ?

    - by ereOn
    Hi, I was recently hired in a company. They have a lot of C++ and C# code source files and almost one different commenting style per file. (Well this is exagerated, but you have the picture) This morning, I show my new collegues how my personnal code was commented and how easy it was to generate a documentation from it (I use Doxygen). I somehow convinced them to use a coherent commenting style. I would suggest using Doxygen for C++ source files and native C# style commenting style for C# files. However, I'm not sure that's the best solution here. Are you aware of a commenting style that would work for both C++ and C# allowing us to generate a documentation from it ? If so, what software/tool should we use ? Having a solution that would work on Linux platforms as well would be even better. Thank you very much.

    Hello All, I been recently playing with F# . I was wondering instead of using a for loop to generate a sequence to element which are multiplied with every other element in the list how can I use a Seq map function or something similar to generate something like below. So for e.g. I have a list [1..10] I would like to apply a fun which generates a result something like [(1*1); (1*2);(1*3); (1*4); (1*5)......(2*1);(2*2);(2*3).....(3*1);(3*2)...] How can i achieve this ?. Many thanks for all you help.

  • prettyPhoto not working in my wordpress theme

    - by codemanic
    So friends I am trying to use prettyPhoto in my wordpress theme but its not working at all. Both of its files - prettyPhoto.css and jquery.prettyPhoto.js are correctly linked in header.php file. This is the linking of the files in my header.php file - <link rel="stylesheet" href="<?php bloginfo('stylesheet_directory'); ?>/js/prettyPhoto/css/prettyPhoto.css" type="text/css" media="screen" title="prettyPhoto main stylesheet" charset="utf-8" /> <script src="<?php bloginfo('stylesheet_directory'); ?>/js/prettyPhoto/js/jquery.prettyPhoto.js" type="text/javascript"></script> Please let me know if this problem is due to not using wp_enqueue_script(). And this is how I link the image to be used with prettyPhoto - <a title="test image" href="images/new-image.png" rel="prettyPhoto[]"><img src="images/new-image.png" alt="Some Alternate Text" /></a> When I click on image, it doesn't open in prettyPhoto.
