  • file_field is not sticky in my Rails form

    - by Tony
    I have a pretty standard Rails form: <div> <h1>Create a New Listing</h1> <%- form_for @listing, :html => {:multipart => true} do |f| -%> <div><%= f.label :title, "Title:"%> <%= f.text_field :title %></div> <div> <%= f.label :image, "Image:" %> <%= f.file_field :image </div> <div> <%= f.label :sound, "Sound Clip:"%> <%= f.file_field :sound %><br /> </div> <div class="submit"><%= f.submit 'Post Listing' %></div> <%- end -%> </div> When a user chooses a file, but the form fails for validation purposes, he must always re-select the file. It is not sticky. Any suggestion on how to fix this? Thanks!

  • jQuery carousel clicks update <select> list's "selected" option to match clicked item's title attrib

    - by Scott B
    The code below allows me to change a preview image outside the carousel widget so that it matches the element under the mouse. For example, if the user mouses over image2's thumbnail, the script updates .selectedImage so that it displays image2's full size version. I'd like to enhance it so that the #myThumbs options listing updates its "selected" option to match the carousel image that receives a click. Mouseover changes the preview image and click changes the select list to match the same name. The items in the carousel will have the same title attribute as the items in the select list, so I would expect that I can pass that value from the carousel to the select list. $(function() { $("#carousel").jCarouselLite({ btnNext: ".next", btnPrev: ".prev", visible: 6, mouseWheel: true, speed: 700 }); $('#carousel').show(); $('#carousel ul li').hover(function(e) { var img_src = $(this).children('img').attr('src'); $('.selectedImage img').attr('src',img_src); } ,function() { $('.selectedImage img').attr('src', '<?php echo $selectedThumb; ?>');}); }); <select id="myThumbs"> <option>image1</option> <option selected="selected">image2</option> <option>image3</option> </select>

  • pdf external streams in Max OS X Preview

    - by olpa
    According to the specification, a part of a PDF document can reside in an external file. An example for an image: 2 0 obj << /Type /XObject /Subtype /Image /Width 117 /Height 117 /BitsPerComponent 8 /Length 0 /ColorSpace /DeviceRGB /FFilter /DCTDecode /F (pinguine.jpg) >> stream endstream endobj I found that this functionality does work in Adobe Acrobat 5.0 for Windows (sample PDF with the image), also I managed to view this file in Adobe Acrobat Reader 8.1.3 for Mac OS X after I found the setting "Allow external content". Unfortunately, it seems that non-Adobe tools ignore the external stream feature. I hope I'm wrong, therefore ask the question: How to enable external streams in Mac OS X? (I think that all the system Mac OS X tools use the same library, therefore say "Mac OS X" instead of "Preview".) Or maybe there could be a programming hook to emulate external streams? My task is: store a big set of images (total ˜300Mb) outside of a small PDF (˜1Mb). At some moment, I want to filter PDF through a quartz filter and get a PDF with the images embedded. Any suggestions are welcome.

  • playing flash movies in lightbox

    - by Cptcecil
    I'm using JQuery and Prototype in this web application that I'm developing. I'm looking for a way to use Lightbox v2.04 by Lokesh Dhakar to play flash movies. If its not possible using the Lightbox v2.04 then what other ways can I accomplish the shadowing overlayed flash video pop-up with jquery and/or Prototype? The reason I'm set on v2.04 is because I'm using it already as an image gallery. I'm using flv type flash files if that helps.

  • Unable to use certain Fonts programatically in ASP.Net

    - by TooFat
    I am trying to programatically create a bitmap with a specified font in ASP.Net. The idea is that the text, font name, size color etc. will be passed in from variables and a bitmap of the text using the font etc will be returned. However, I have been finding that I am only able to do so using the following code with certain fonts. <div> <% string fontName = "Segoe Script"; //Change Font here System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); System.Drawing.Font fnt = new System.Drawing.Font(fontName, 20); System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(System.Drawing.Color.Red); graph.DrawString("Help", fnt, brush, new System.Drawing.Point(10, 10)); bmp.Save(@"C:\Development\Path\image1.bmp"); this.Image1.ImageUrl = "http://mysite/Images/image1.bmp"; %> <asp:Label ID="Label1" runat="server" Text="Label" Font-Names="Segoe Script"> <%Response.Write("Help"); %></asp:Label> //Change font here <asp:Image ID="Image1" runat="server" /> </div> If I change the font name in the areas indicated by the comments to Arial or Verdana both the image and the label appear with the correct font. If however, I change the font name in both locations to something "Segoe Script" the Label will show up in Segoe Script but the image is in what looks like Arial.

  • Pymedia video encoding failed

    - by user1474837
    I am using Python 2.5 with Windows XP. I am trying to make a list of pygame images into a video file using this function. I found the function on the internet and edited it. It worked at first, than it stopped working. This is what it printed out: Making video... Formating 114 Frames... starting loop making encoder Frame 1 process 1 Frame 1 process 2 Frame 1 process 2.5 This is the error: Traceback (most recent call last): File "ScreenCapture.py", line 202, in <module> makeVideoUpdated(record_files, video_file) File "ScreenCapture.py", line 151, in makeVideoUpdated d = enc.encode(da) pymedia.video.vcodec.VCodecError: Failed to encode frame( error code is 0 ) This is my code: def makeVideoUpdated(files, outFile, outCodec='mpeg1video', info1=0.1): fw = open(outFile, 'wb') if (fw == None) : print "Cannot open file " + outFile return if outCodec == 'mpeg1video' : bitrate= 2700000 else: bitrate= 9800000 start = time.time() enc = None frame = 1 print "Formating "+str(len(files))+" Frames..." print "starting loop" for img in files: if enc == None: print "making encoder" params= {'type': 0, 'gop_size': 12, 'frame_rate_base': 125, 'max_b_frames': 90, 'height': img.get_height(), 'width': img.get_width(), 'frame_rate': 90, 'deinterlace': 0, 'bitrate': bitrate, 'id': vcodec.getCodecID(outCodec) } enc = vcodec.Encoder(params) # Create VFrame print "Frame "+str(frame)+" process 1" bmpFrame= vcodec.VFrame(vcodec.formats.PIX_FMT_RGB24, img.get_size(), # Covert image to 24bit RGB (pygame.image.tostring(img, "RGB"), None, None) ) print "Frame "+str(frame)+" process 2" # Convert to YUV, then codec da = bmpFrame.convert(vcodec.formats.PIX_FMT_YUV420P) print "Frame "+str(frame)+" process 2.5" d = enc.encode(da) #THIS IS WHERE IT STOPS print "Frame "+str(frame)+" process 3" fw.write(d.data) print "Frame "+str(frame)+" process 4" frame += 1 print "savng file" fw.close() Could somebody tell me why I have this error and possibly how to fix it? The files argument is a list of pygame images, outFile is a path, outCodec is default, and info1 is not used anymore. UPDATE 1 This is the code I used to make that list of pygame images. from PIL import ImageGrab import time, pygame pygame.init() f = [] #This is the list that contains the images fps = 1 for n in range(1, 100): info = ImageGrab.grab() size = info.size mode = info.mode data = info.tostring() info = pygame.image.fromstring(data, size, mode) f.append(info) time.sleep(fps)

  • JApplet behaving unexpectedly

    - by JohnW
    import java.awt.Graphics; import java.awt.Image; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JApplet; import javax.swing.Timer; public class CountingSheep extends JApplet { private Image sheepImage; private Image backgroundImage; private GameBoard gameBoard; private scoreBoard scoreBoard; public void init() { loadImages(); gameBoard = new GameBoard(sheepImage, backgroundImage); scoreBoard = new scoreBoard(); getContentPane().add(gameBoard); getContentPane().add(scoreBoard); } public void loadImages() { sheepImage = getImage(getDocumentBase(), "sheep.png"); backgroundImage = getImage(getDocumentBase(), "bg.jpg"); } } Update guys: Alright, first of all, thank you very much for all the help you've given so far (specifically creemam and Hovercraft Full of Eels), and your persistence. You've helped me out a lot as this is incredibly important (i.e. me passing my degree). The problem now is: The program works correctly when nothing but the GameBoard class is added to the JApplet, however, when I try to add the ScoreBoard class, both Panel classes do not show on the Applet. I'm guessing this is now down to positioning? Any ideas? EDIT: Gone back to the previously asked question Hovercraft, and found it was due to the layout of the contentPane and the order at with the components were added. Thanks to all of you so much. People like you make the development community a bit of alright.

  • How do I create a Status Icon / System Tray Icon with custom text and transparent background using P

    - by Raugturi
    Here is the code that I have so far to define the icon: icon_bg = gtk.gdk.pixbuf_new_from_file('gmail.png') w, h = icon_bg.get_width(), icon_bg.get_height() cmap = gtk.gdk.Colormap(gtk.gdk.visual_get_system(), False) drawable = gtk.gdk.Pixmap(None, w, h, 24) drawable.set_colormap = cmap gc = drawable.new_gc() drawable.draw_pixbuf(gc, icon_bg, 0, 0, 0, 0, w, h) drawn_icon = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, False, 8, w, h) drawn_icon.get_from_drawable(drawable, cmap, 0, 0, 0, 0, w, h) icon = gtk.status_icon_new_from_pixbuf(drawn_icon) This works to get the png into the icon, but falls short in two areas. First, transparency is not working. If I use a 22x22 png with transparent background and the image centered, I end up with sections of other active icons showing up inside of mine, like this: http://i237.photobucket.com/albums/ff311/Raugturi/22x22_image_with_transparency.png The icon it choose to steal from is somewhat random. Sometimes it's part of the dropbox icon, others the NetworkManager Applet. If I instead use this code: icon_bg = gtk.gdk.pixbuf_new_from_file('gmail.png') w, h = icon_bg.get_width(), icon_bg.get_height() cmap = gtk.gdk.Colormap(gtk.gdk.visual_get_system(), False) drawable = gtk.gdk.Pixmap(None, w, h, 24) drawable.set_colormap = cmap gc = drawable.new_gc() drawable.draw_pixbuf(gc, icon_bg, 0, 0, 0, 0, w, h) drawn_icon = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, False, 8, 22, 22) drawn_icon.get_from_drawable(drawable, cmap, 0, 0, 3, 6, w, h) icon = gtk.status_icon_new_from_pixbuf(drawn_icon) And an image that is only 16x11 with the transparent edges removed, what I end up with is this: Same URL but file is 16x11_image_positioned_in_middle.png So how do I end up with a transparent block like the 1st one that doesn't pull in stuff from other icons? As for the second problem, I need the ability to write on the image before converting it to the icon. I tried using draw_glyphs and it told me I should be using Pango layout/context instead. Unfortunately all the Pango tutorials I could find deal with actual windows, not the status icon. Is there a good tutorial out there for Pango that would apply to this issue (and also maybe have at least some explanation of how to tell it what font to use as all of them that I found seem to lack this and it won't write anything without it). Note: Sorry for the lack of actual images and only one working link, apparently this is a spam prevention feature due to my lack of reputation.

    I have a table for image gallery with four columns like: foid | uid | pic1 | pic2 | pic3 | date | ----------------------------------------------- 104 | 5 | 1.jpg | 2.jpg | 3.jpg | 2010-01-01 105 | 14 | 8.jpg | | | 2009-04-08 106 | 48 | x.jpg | y.jpg | | 2010-08-09 Mysql query for the user's galleries looks like: SELECT * FROM foto WHERE uid = $id order by foid DESC The thing that I want to do is count the number of images (PIC1, PIC2, PIC3) in every of the listed galleries. What is the best way for doing that?

  • CSS "Cover" - No scroll bars?

    - by Lynda
    I am using the cover property to create a background image that fills the background and resizes with the browser. But I run into one issue, the page has a lot of content and no scroll bars appear for me to scroll down! Here is the code I am using: body{ background: url(path.jpg) no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; /* Cover for IE 7/8 */ filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='path.jpg', sizingMethod='scale'); -ms-filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='path.jpg', sizingMethod='scale'); /* End Cover for IE 7/8 */ background-size: cover; background-color: transparent !important; position:fixed; top: 0; left: 0; width: 100%; height:100%; max-width:2500px; max-height:1500px; z-index:1; } If I remove position:fixed; I get the scroll bars back but the background image disappears. What is the best way to tackle this and have both scroll bars and the background cover image? Note: I am using jQuery and would use a JS answer if it works (though I prefer a CSS only answer.)

  • jquery CSS doesn't work in webkit

    - by Mauro74
    I'm trying to apply some css to an image tag if the image is portrait, but for some reason .css() doesn't work in webkit. Basically the image tag doesn't get the 'style' property. Here's my code: $(document).ready(function () { $('.listing .item .thumb img').each(function () { var _img = $(this); var _imgWidth = _img.outerWidth(); var _imgHeight = _img.outerHeight(); if (_imgHeight > _imgWidth) { _img.css('top', '-40%'); } }); }); <div class="listing about"> <div class="item"> <a href="#" class="thumb"> <img src="../_uploads/siteassets/images/thumb-carousel-2.jpg" /> <span class="frame"></span> </a> <span class="snippet"> <a href="#" class="title">Name Surname</a> <span class="date">Role in the company</span> <p class="description">Lorem ipsum dolor sit amet...</p> </span> </div> </div> I've tried to use .attr() instead of .css() but nothing. It doesn't work! Any idea why?

  • Archiver Securing SQLite Data without using Encryption on iPhone

    - by Redrocks
    I'm developing an iphone app that uses Core Data with a SQLite data store and lots of images in the resource bundle. I want a "simple" way to obfuscate the file structure of the SQLite database and the image files to prevent the casual hacker/unscrupulous developer from gaining access to them. When the app is deployed, the database file and image files would be obfuscated. Upon launching the app it would read in and un-obfuscate the database file, write the un-obfuscated version to the users "tmp" directory for use by core data, and read/un-obfuscate image files as needed. I'd like to apply a simple algorithm to the files that would somehow scramble/manipulate the file data so that the sqlite database data isn't discernible when the db is opened in a text editor and so that neither is recognized by other applications (SQLite Manager, Photoshop, etc.) It seems, from the information I've read, that I could use NSFileManager, NSKeyedArchiver, and NSData to accomplish this but I'm not sure how to proceed. Been developing software for many years but I'm new to everything CocoaTouch, Mac and iPhone. Also never had to secure/encrypt my data so this is new. Any thoughts, suggestions, or links to solutions are appreciated.

  • Object Oriented Programming Problem

    - by Danny Love
    I'm designing a little CMS using PHP whilst putting OOP into practice. I've hit a problem though. I have a page class, whos constructor accepts a UID and a slug. This is then used to set the properties (unless the page don't exist in which case it would fail). Anyway, I wanted to implement a function to create a page, and I thought ... what's the best way to do this without overloading the constructor. What would the correct way, or more conventional method, of doing this be? My code is below: <?php class Page { private $dbc; private $title; private $description; private $image; private $tags; private $owner; private $timestamp; private $views; public function __construct($uid, $slug) { } public function getTitle() { return $this->title; } public function getDescription() { if($this->description != NULL) { return $this->description; } else { return false; } } public function getImage() { if($this->image != NULL) { return $this->image; } else { return false; } } public function getTags() { if($this->tags != NULL) { return $this->tags; } else { return false; } } public function getOwner() { return $this->owner; } public function getTimestamp() { return $this->timestamp; } public function getViews() { return $this->views; } public function createPage() { // Stuck? } }

  • How to use Facebook graph API to retrieve fan photos uploaded to wall of fan page?

    - by Joe
    I am creating an external photo gallery using PHP and the Facebook graph API. It pulls thumbnails as well as the large image from albums on our Facebook Fan Page. Everything works perfect, except I'm only able to retrieve photos that an ADMIN posts to our page. (graph.facebook.com/myalbumid/photos) Is there a way to use graph api to load publicy uploaded photos from fans? I want to retrieve the pictures from the "Photos from" album, but trying to get the ID for the graph query is not like other albums... it looks like this: http://www.facebook.com/media/set/?set=o.116860675007039 Another note: The only way i've come close to retreiving this data is by using the "feed" option.. ie: graph.facebook.com/pageid/feed EDIT: This is about as far as I could get- it works, but has certain issues stated below. Maybe someone could expand on this, or provide a better solution. (Using FB PHP SDK) <?php require_once ('config.php'); // get all photos for album $photos = $facebook->api("/YourID/tagged"); $maxitem =10; $count = 0; foreach($photos['data'] as $photo) { if ($photo['type'] == "photo"): echo "<img src='{$photo['picture']}' />", "<br />"; endif; $count+= 1; if ($count >= "$maxitem") break; } ?> Issues with this: 1) The fact that I don't know a method for graph querying specific "types" of Tags, I had to run a conditional statement to display photos. 2) You cannot effectively use the "?limit=#" with this, because as I said the "tagged" query contains all types (photo, video, and status). So if you are going for a photo gallery and wish to avoid running an entire query by using ?limit, you will lose images. 3) The only content that shows up in the "tagged" query is from people that are not Admins of the page. This isn't the end of the world, but I don't understand why Facebook wouldn't allow yourself to be shown in this data as long as you posted it "as yourself" and not as the page.

  • IE6 transparency+radio button can't be clicked

    - by Jonas Byström
    IE6: when I place a partially transparent image in a div, the radio buttons in that div that overlap the non-transparent pixels of the image become unclickable. Example: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <style media="screen" type="text/css"> div { position: relative; width: 500px; height: 300px; _filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src=http://upload.wikimedia.org/wikipedia/commons/thumb/f/fc/Olympic_flag_transparent.svg/200px-Olympic_flag_transparent.svg.png, sizingMethod='crop'); } input { position: absolute; top: 40px; left: 60px; } </style> </head> <body> <div> <input type="radio" value="1" name="1"/> </div> </body> </html> If you test the code, you can also try moving the button from (60, 40) to (40, 40) where the image is transparent, and voilà - the clicking is back in business again. This bug might, or might not, be related to the IE6 links transparency bug, but I'm not knowledgable enough to grasp any resemblence. Have I done something wrong? Or how can I circumvent? Is there some other option apart from removing the _filter:progid?

By touching the cell or button(play button) on the image a video is loaded and played. I need to delete the cell by touching delete button. If I touched the delete button the corresponding video is deleted from library . But, how to delete the cell and all remaining data in it ? I am not able to delete the cells or the data in the cells. How to do it ? I used these.

  • Getting a UIImage from MySQL using PHP and jSON

    - by Daniel
    I'm developing a little news reader that retrieves the info from a website by doing a POST request to a URL. The response is a jSON object with the unread-news. E.g. the last news on the App has a timeStamp of "2013-03-01". When the user refreshes the table, it POSTS "domain.com/api/api.php?newer-than=2013-03-01". The api.php script goes to the MySQL database and fetches all the news posted after 2013-03-01 and prints them json_encoded. This is // do something to get the data in an array echo $array_of_fetched_data; for example the response would be [{"title": "new app is coming to the market", "text": "lorem ipsum dolor sit amet...", image: XXX}] the App then gets the response and parses it, obtaining an NSDictionary and adds it to a Core Data db. NSDictionary* obtainedNews = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error]; My question is: How can I add an image to the MySQL database, store it, pass it using jSON trough a POST HTTP Request and then interpret it as an UIImage. It's clear that to store an UIImage in CoreData, they must be transform into/from NSData. How can I pass the NSData back and forth to a MySQL db using php and jSON? How should I upload the image to the db? (Serialized, as a BLOB, etc)

  • HTC Incredible displaying blank ImageView

    - by Todd
    HI, I have an app that displays an an image in an ImageView using the setImageDrawable(Drawable) method. However, with the release of the Droid Incredible the images are coming up as a blank screen. I am using Drawable.createFromPath(Environment.getExternalStorageDirectory() + "\imagefile") to access the image from the SD card. I don't get any sort of error, just a black screen. I will get a null pointer exception if after trying to load the image I try to access a property of the Drawable. This makes me believe that the Drawable wasn't loaded, but I don't know why or how to make it work. This code as been working on all other Android devices, so I'm not sure what is different with the Incredible. Unfortunately I don't have access to an Incredible to test on, so I've got to rely on others to test and send me the log files. Any help you can offer would be greatly appreciated. If anyone knows how to replicate this issue on the emulator, that would be helpful too. I've configured an emulator with firmware 7 and the correct screen resolution, but I was unable to replicate the issue. Thanks.

  • Setting objct literal property value via asynchronous callback.

    - by typeof
    I'm creating a self-contained javascript utility object that detects advanced browser features. Ideally, my object would look something like this: Support = { borderRadius : false, // values returned by functions gradient : false, // i am defining dataURI : true }; My current problem deals with some code I'm adapting from Weston Ruter's site which detects dataURI support. It attempts to use javascript to create an image with a dataURI source, and uses onload/onerror callbacks to check the width/height. Since onload is asynchronous, I lose my scope and returning true/false does not assign true/false to my object. Here is my attempt: Support = { ... dataURI : function(prop) { prop = prop; // keeps in closure for callback var data = new Image(); data.onload = data.onerror = function(){ if(this.width != 1 || this.height != 1) { that = false; } that = true; } data.src = "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw=="; return -1; }(this) }; I'm executing the anonymous function immediately, passing this (which I hoped was a reference to Support.dataURI), but unfortunately references the window object -- so the value is always -1. I can get it to work by using an externally defined function to assign the value after the Support object is created... but I don't think it's very clean that way. Is there a way for it to be self-contained? Can the object literal's function reference the property it's assigned to?

    This might be a little complicated. See code below. When image is clicked I want to change "MY-ID-NUMBER" in "value" and "src" of object. But I want the other information to remain. When link is clicked I want to restore "value" and "src" so I can use the same function for next image that is clicked. Is it possible? Please help! My HTML: <img height="186" width="134" alt="4988" src="i123.jpg"> <img height="186" width="134" alt="4567" src="i124.jpg"> <a class="restore-to-default" href="#">DVD</a> <div class="tdt"> <object width="960" height="540"><param name="movie" value="http://www.domain.com/v3.4/player.swf?file=http://se.player-feed.domain.com/cinema/MY-ID-NUMBER/123-1/><param name="wmode" value="transparent" /><param name="allowFullScreen" value="true" /><param name="allowScriptAccess" value="always" /><embed id="player" name="player" type="application/x-shockwave-flash" src="http://www.player.domain.com/v3.4/player.swf?file=http://se.player-feed.domain.com/cinema/MY-ID-NUMBER/123-1/&display_title=over&menu=true&enable_link=true&default_quality=xxlarge&controlbar=over&autostart=true&backcolor=000000&frontcolor=ffffff&share=0&repeat=always&displayclick=play&volume=80&linktarget=_blank" width="960" height="540"allowFullScreen="true" allowScriptAccess="always"></embed></object> My jquery: $('img').click(function(){ var alt = $(this).attr("alt"); $('.tdt object').val("alt", alt); // Some how change "MY-ID-NUMBER" into the "alt-value" of image }); $('a').click(function(){ //restore to "MY-ID-NUMBER" }); Thanks!

  • Escape whitespace in paths using nautilus script

    - by Tommy Brunn
    I didn't think this would be as tricky as it turned out to be, but here I am. I'm trying to write a Nautilus script in Python to upload one or more images to Imgur just by selecting and right clicking them. It works well enough with both single images and multiple images - as long as they don't contain any whitespace. In fact, you can upload a single image containing whitespace, just not multiple ones. The problem is that NAUTILUS_SCRIPT_SELECTED_FILE_PATHS returns all the selected files and directories as a space separated string. So for example, it could look like this: print os.environment['NAUTILUS_SCRIPT_SELECTED_FILE_PATHS'] /home/nevon/Desktop/test image.png /home/nevon/Desktop/test.jpg What I need is a way to -either in bash or Python- escape the spaces in the path - but not the spaces that delimit different items. Either that, or a way to put quotation marks around each item. The ultimate solution would be if I could do that in bash and then send the items as separate arguments to my python script. Something like: python uploader.py /home/nevon/Desktop/test\ image.png /home/nevon/Desktop/test.jpg I've tried RTFM'ing, but there doesn't seem to be a lot of good solutions for this. At least not that I've found. Any ideas?

  • use a sprite png in li-class and display in div

    - by bonny
    hello i have some problem with displaying a sprite in a div that is in a li-class. so the structure is: <li id="aa"> <div><a href="#">one</a></div> </li> and the css: li{ width: 120px; height: 18px; margin-top: 5px; } li div{ width: 20px; height: 10px; background-image:url(../images/sprite.png) background-repeat: no-repeat; margin-left: 0px; font-weight:bolder; border: 1px solid #fff; } when i use this i can see the sprite even outside the div. so i tried adding to li background-image: none; that makes the image in the div not visible too. so if there is someone who know about that i really would appreciate. thanks alot.

  • Multiple/repeat .replace on one page

    - by Kenneth B
    I've made a script which copies the ALT-tag of an image and puts it into a SPAN. It also formates the information devided by a hyphen. It works like a charm, but only with one image. Further more, I would like it to wrap a div around the image, to prevent unnecessary markup, as I have now. Any ideas is much appreciated... :-) Script that works now: HTML: <div id="hoejre"> <p><span class="alignright"><img src="tommy_stor.jpg" alt="Name - Title" width="162" height="219" /><span></span></span></p> </div> jQuery: var alt = $("#hoejre p span img").attr("alt"); $('#hoejre p span span').html("<strong>" + alt.replace("-", "</strong> <em>") + "</em>"); Output: <span class="alignright"><img height="219" width="162" alt="Name - Title" src="tommy_stor.jpg"><span><strong>Name </strong> <em> Title</em></span></span> How do you I repeat the effect on several images, with different information within? P.S.: I really love this forum. I have used several other forums for this kind of questions, but this one is by far the most professional.
