  • DIV Overlaying DIV, links in backmost DIV non-accessible

    - by Shawn
    I have a photoshop image that is 500x600 that I am using as a background image for the first div. The second div sits over top of the first div and is populated with images. The z-index of the first div is set to 100. The effect is the photoshop image sits over top of all of the smaller images. The photoshop image is a letter with the inner-content of it set to be transparent and the small images create the filling. Each of the small images however is a link, but none of the links are accessible. How can I remedy that? I would post the code here, but I have absolutely no clue how to format it. I quite simply do not understand typing a backtick followed by the tab key and then a dollar sign. All that ends up is I type a backtick here followed by a dollar sign in the Tags section below.

  • Cannot delete an image file that is shown in a listview

    - by Enrico
    Hello all, In my listview I show thumbnails of small images in a certain folder. I setup the listview as follows: var imageList = new ImageList(); foreach (var fileInfo in dir.GetFiles()) { try { var image = Image.FromFile(fileInfo.FullName); imageList.Images.Add(image); } catch { Console.WriteLine("error"); } } listView.View = View.LargeIcon; imageList.ImageSize = new Size(64, 64); listView.LargeImageList = imageList; for (int j = 0; j < imageList.Images.Count; j++) { var item = new ListViewItem {ImageIndex = j, Text = "blabla"}; listView.Items.Add(item); } The user can rightclick on an image in the listview to remove it. I remove it from the listview and then I want to delete this image from the folder. Now I get the error that the file is in use. Of course this is logical since the imagelist is using the file. I tried to first remove the image from the imagelist, but I keep on having the file lock. Can somebody tell me what I am doing wrong? Thanks!

  • Swap CSS class on the basis of Scroll Position with Javascript

    - by Brian
    I'm looking to re-create the Apple Store shopping cart sidebar. http://store.apple.com/us/configure/MB535LL/A?mco=MTA4MTg3NTQ It is similar to "position: fixed" except that it starts out as "position: absolute" with the CSS class "pinned_top" and then switches to CSS class "floating" when a certain scroll-y position is reached. I've looked EVERYWHERE for this, it seems a tutorial should be obvious but I'm yet to find anything. Any help?

  • System architecture: simple approach for setting up background tasks behind a web application -- wil

    - by Tim Molendijk
    I have a Django web application and I have some tasks that should operate (or actually: be initiated) on the background. The application is deployed as follows: apache2-mpm-worker; mod_wsgi in daemon mode (1 process, 15 threads). The background tasks have the following characteristics: they need to operate in a regular interval (every 5 minutes or so); they require the application context (i.e. the application packages need to be available in memory); they do not need any input other than database access, in order to perform some not-so-heavy tasks such as sending out e-mail and updating the state of the database. Now I was thinking that the most simple approach to this problem would be simply to piggyback on the existing application process (as spawned by mod_wsgi). By implementing the task as part of the application and providing an HTTP interface for it, I would prevent the overhead of another process that is holding all of the application into memory. A simple cronjob can be setup that sends a request to this HTTP interface every 5 minutes and that would be it. Since the application process provides 15 threads and the tasks are quite lightweight and only running every 5 minutes, I figure they would not be hindering the performance of the web application's user-facing operations. Yet... I have done some online research and I have seen nobody advocating this approach. Many articles suggest a significantly more complex approach based on a full-blown messaging component (such as Celery, which uses RabbitMQ). Although that's sexy, it sounds like overkill to me. Some articles suggest setting up a cronjob that executes a script which performs the tasks. But that doesn't feel very attractive either, as it results in creating a new process that loads the entire application into memory, performs some tiny task, and destroys the process again. And this is repeated every 5 minutes. Does not sound like an elegant solution. So, I'm looking for some feedback on my suggested approach as described in the paragraph before the preceeding paragraph. Is my reasoning correct? Am I overlooking (potential) problems? What about my assumption that application's performance will not be impeded?

  • How do I use the subversion revision of a css file to prevent browser cache

    - by Clayton
    StackOverflow implements it like this: <link rel="stylesheet" href="http://sstatic.net/so/all.css?v=4542"> Every time the referenced files change, the href attribute of the link tag is updated in the HTML code, thus supporting caching and updated referenced files. My question - how do you retrieve the subversion version of that css file to include in the link? Subversion keywords only tell you the revision of the file you are currently in. I'm working with PHP/CodeIgniter + jQuery.

  • Z-Index and javascript for rollover

    - by Raffaele
    I have a container (div) with a background image. In this div there is a menu - a horizontal list. What I need is to insert an image onMouseOver, positioning it absolutely, and showing it behind the text (of course!) AND on top of the div's background image. I also use jQuery, but I think this doesn't matter. The problem can be viewed online. Go to http://www.w3schools.com/css/tryit.asp?filename=trycss_zindex and paste the following text <html> <head> <style type="text/css"> img { top: 0; left: 0; position:absolute; z-index:-1; } #main { color: red; margin: 30px; padding: 20px; width: 700px; min-height: 400px; z-index: -2; background-image: url("http://www.google.com/logos/mother10-hp.gif"); background-repeat: no-repeat; } </style> </head> <body> <div id="main"> <h1>Z-Index question:</h1> <img src="w3css.gif" width="100" height="140" /> <p>How can we place the green pic between the text and the div#main?</p> <p>I need the green gif to appear</p> <ol> <li>On top of #main's background image</li> <li>Behind the text</li> </ol> </div> </body> </html>

  • DMG mounting warning message says "it may make computer less secure or cause other problems"

    - by Cawas
    When I try to open a DMG file I get this: I'll just transcript the image: There may be a problem with this disk image. Are you sure you want to open it? Opening this disk image may make your computer less secure or cause other problems. What does that mean in fact? What's really wrong with it, and what kind of problem can it cause just by mounting? Someone said: When you download a file in Leopard (and Snow Leopard), it's marked as a quarantined file. This occurs by the OS adding an attribute to the file, tagging where it came from (such as "downloaded by Safari"). This is what causes the user to see prompts when running files that were downloaded from the Internet, you may remember being asked to confirm you'd like to launch program XXX downloaded by Safari on XXX date. As a new part of Snow Leopard, files which are tagged with the quarantine attribute also have integrity checked by fsck, and if that verify fails you will see the message you described, triggered by an unused node in the disc image. But really, I didn't get that. What's quarantine? I've just downloaded a file here on SL, tried to open, and got that warning. Apple have a say about quarantine files, and they seem to work the same on Leopards. Plus I have got that file using Google Chrome while that feature seems to work just with Safari.

  • jquery image hover popup cant detect browser edge and change its direction

    - by Salman
    hi guys i am trying to implement jquery image hover popup but facing a problem when the popup is closer to browser edge it goes beyond its edge i want it to change its direction when it finds that space is not enough to show that popup, i have see this effect in many plugins where popups, tooltips and drop down menus change their direction if they are close to browser window edge can any one guide me in right direction here is the screen shot for reference http://img512.imageshack.us/img512/4990/browseredge.png here is the jquery hover code function imagePreview(){ /* CONFIG */ xOffset = 10; yOffset = 30; // these 2 variable determine popup's distance from the cursor // you might want to adjust to get the right result /* END CONFIG */ $("a.preview").hover(function(e){ this.t = this.title; this.title = ""; var c = (this.t != "") ? "<br>" + this.t : ""; var newName = this.name; //console.log(this.name); newName=newName.replace("/l/","/o/"); //console.log(newName); $("body").append("<p id='preview'><img src='"+ this.name +"' alt='Image preview' style='margin-bottom:5px;'>"+ c +"</p>"); $("#preview img").error(function () { $("#preview img").attr("src" ,newName).css({'width': '400px', 'height': 'auto'}); }); $("#preview") .css("top",(e.pageY - xOffset) + "px") .css("left",(e.pageX + yOffset) + "px") .fadeIn("fast"); }, function(){ this.title = this.t; $("#preview").remove(); }); $("a.preview").mousemove(function(e){ $("#preview") .css("top",(e.pageY - xOffset) + "px") .css("left",(e.pageX + yOffset) + "px"); }); }; any help will be appriciated Thanks Salman

  • Deploying workstations - best practices?

    - by V. Romanov
    Hi guys I've been researching on the subject of workstation deployment for a while, and found a ton of info and dozens different methods and tools, but no "best practice" method that doesn't lack at least one feature that i consider required for the solution to be perfect. I'm currently interested in windows workstation deployment, but if the tools can be extended to Linux, then it's an added value. I want the deployment tools I use to be able to do the following: hardware independent - I want my image or installation to have a minimum of hardware and driver dependency, so that i can use a single image/package for all workstations easily updatable - I want to be able to update my image as easily as possible without redeploying/rebuilding/reimaging all configurations PXE bootable deployment - I want the tools to be bootable off the network so that I don't need a boot cd/DOK. scriptable for minimum human input - Ideally, the tool should run automatically after being booted and perform a "default" deployment (including partitioning) unless prompted otherwise. i.e - take a pc, hook it up, power on, PXE boot and forget about it until the OS is deployed. I found no single product or environment that does all this. Closest i came to is the windows deployment services/WIM image format. I also checked out numerous imaging and deployment tools including clonezilla, ghost, g4u, wpkg and others, but most of them lack the hardware Independence and updatability features. We currently have a Symantec Ghost server setup that does imaging over the network, but I'm not satisfied with it as it has all the drawbacks i listed above. Do you have suggestions how to optimize the process of workstation deployment? How do you deploy them in your organization? Thanks! Vadim.

  • How to i disable the _moz_resizing?

    - by Shripad K
    I am using nicEdit editor and i have added my own custom image resizing script to it. But i want to disable the default _moz_resizing that appears in firefox. I wanted to have finer control over the image being resized. ( Eg: Allow only the image to resize and inherit the width of the parent container. ) So i wrote a custom script. But since firefox has its own image resizing control (_moz_resizing) how do i disable it? If there is no way to do so, i have a very simple workaround where i browser detect firefox and turn off my custom script and use the _moz_resizing instead. But i won't have fine grained control and will have to rely on there being now browser bugs in firefox. :(

  • Replace image in word doc using OpenXML

    - by fearofawhackplanet
    Following on from my last question here OpenXML looks like it probably does exactly what I want, but the documentation is terrible. An hour of googling hasn't got me any closer to figuring out what I need to do. I have a word document. I want to add an image to that word document (using word) in such a way that I can then open the document in OpenXML and replace that image. Should be simple enough, yes? I'm assuming I should be able to give my image 'placeholder' an id of some sort and then use GetPartById to locate the image and replace it. Would this be the correct method? What is this Id? How do you add it using Word? Every example I can find which does anything remotely similar starts by building the whole word document from scratch in ML, which really isn't a lot of use. EDIT: it occured to me that it would be easier to just replace the image in the media folder with the new image, but again can't find any indication of how to do this.

  • Faster image loading

    - by nemiss
    I want to display about 5-8 images on my page, one by one, but I would like them to pre-load one and not loading them each time i switch to anohter image. I have seen some examples where they have all images (hidden) on the page something like: <a href=""><img id="img1" src="images/image1.png" class="image" alt="" /></a> <a href=""><img id="img2" src="images/image1.png" class="image" alt="" /></a> <a href=""><img id="img3" src="images/image1.png" class="image" alt="" /></a> And the unhide the current image. And what I have is one image that i change it's src attribute for path for new images from th array. SwitchNextImage: function(){ var theimg=document.getElementById("imgContainer"); this.currentIndex = this.currentIndex+ 1 == this.totalImageCount ? 0 : this.currentIndex + 1; theimg.src=this.slideimages[this.currentIndex].src; } The first method is obviously faster loading. But requies static links. My questions is how can I make my method more faster loading?
