  • jQuery: Replace strings with .each()

    - by Warrantica
    I want a function that replace each li with an image. This is my code: $(document).ready(function(){ var tmphref; var tmpname; var str = '<a href="' + tmphref + '"><img src="http://www.somesite.com/a/' + tmpname[1] + '/avatar-small.jpg /></a>'; $('#somediv li a').each(function(){ tmphref = $(this).attr("href"); tmpname = /http\:\/\/(\w+)\.somesite\.com\//.exec(tmphref); $(this).parent().replaceWith(str); }); }); The image is in this specific path: www.somesite.com/a/username/avatar-small.jpg The code above doesn't work. Any ideas? Thank you in advance.

  • jQuery: set the width of a textarea?

    - by AP257
    What it says on the tin: how do I set the width of a textarea in jQuery? I want to set the width of a textarea to match the width of a particular image. Using .width() works for setting the width of an image, but not of a textarea. $(document).ready(function() { var width = $("#my_image").width(); $("#another_image").width(width); // works $("#my_textarea").width(width); // fails }); How do I set the width of a textarea?

  • Looking for a Toolbox (Crop/Position/Rotate) for a Website

    - by VIRTUALWEB
    I'm looking for a Toolbox for a Website that can do the following things: Write Text in a Text Editor (change its color/font size/font) and display it over an product image (plus drag&drop, do rotation). As Texteditor i could use TinyMCE but how to rotate/drag&drop? the same with images (upload a logo, display it over an existing product image) where the user could drag&drop it around or rotate it left/right in 90 degrees, and change its size. are there any tools outside that can handle that requirements? They could be AJAX, Flash, jQuery, JavaScript, ... tia

  • How to make show desktop work only on the current workspace?

    - by thenasko
    I am an active user of workspaces in Ubuntu. Until recently, pressing Ctrl+Alt+D (show desktop) acted only on the current workspace. For example, one might want to minimize the applications in the current workspace, open a file, and then bring some of them back. The current implementation works on all workspaces uniformly which is counter-intuitive to me. The reason for the existence of workspaces is the separation of logic -- one can have a browser open in one workspace, a text editor in another, a terminal in a third. The current functionality goes against this idea. Is there a way to restrict the action of the show desktop command to a single workspace only?

  • NoMethodError when using .where (eager fetching)

    - by Ethan Leroy
    I have the following model classes... class Image < ActiveRecord::Base attr_accessible :description, :title has_many :imageTags has_many :tags, :through => :imageTags end class Tag < ActiveRecord::Base attr_accessible :name has_many :imageTags has_many :images, :through => :imageTags end class ImageTag < ActiveRecord::Base attr_accessible :position belongs_to :image belongs_to :tag end And when I use find for getting the Tag with the id 1 t = Tag.find(1); @images = t.images; But when I do the same with where, I get a NoMethodError, with the description undefined method 'images': t = Tag.where(:name => "foo"); @images = t.images; I also tried adding .includes(:images) before the .where statement, but that doesn't work too. So, how can I get all Images that belong to a Tag?

  • How to find the real problem line in my code with Application Verifier ?

    - by Newbie
    I am now trying to use this Application Verifier debugging tool, but i am stuck, first of all: it breaks the program at a line that is simple variable set line (s = 1; for example) Secondly, now when i run this program under debugger, my program seems to have changed its behaviour: i am drawing image, and now one of the colors has changed o_O, all those parts of the image that i dont draw on, has changed the color to #CDCDCD when it should be #000000, and i already set the default color to zero, still it becomes to #CDCDCD. How do i make any sense to this? Here is the output AV gave me: VERIFIER STOP 00000002: pid 0x8C0: Access violation exception. 14873000 : Invalid address causing the exception 004E422C : Code address executing the invalid access 0012EB08 : Exception record 0012EB24 : Context record AVRF: Noncontinuable verifier stop 00000002 encountered. Terminating process ... The program '[2240] test.exe: Native' has exited with code -1073741823 (0xc0000001).

  • Displaying a well formatted table

    Please take a look at the picture below. The header for the second column is displaying DISTRICT under SENATORIAL. But that's not the case for the 2nd and 3rd Rows under the 2nd Column. What I want to achieve is that words/strings should not ba able to extend width of the table.... The CSS I'm using is beneath. table { width: 650px; font-family: calibri; word-wrap: break-word; margin-left: 115px; } th { padding: 3px; color: white; text-transform: uppercase; font-size: 12px; background-image: url(navbg.png); font-weight: normal; word-wrap: break-word; font-family: "Trebuchet MS"; } Image:

  • JButtons don't imediatly change on mouse event

    - by out_sider
    I'm using the java swing library to develop a board game called DAO. The problem is that after the human player makes its move, by clicking on the JButton with the piece image that he wants to play, I call the computer AI routine but inside the mouse event function. By doing this only when the function returns, the computer ends its turn, do the JButtons refresh their Images (setIcon comes in). I'd like to know how can I force the JButtons to change their image at the moment they are clicked and not only when the mouse event function ends (as I need to handle data inside it). I've tried all of this myButtons[i][j].setIcon(xIcon); myButtons[i][j].revalidate(); myButtons[i][j].repaint(); myButtons[i][j].validate(); None worked. Thx in advance

  • 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.

Here is my code used to draw the background image: void drawFrame() { final SurfaceHolder holder = getSurfaceHolder(); Canvas c = null; try { c = holder.lockCanvas(); if (c != null) { c.drawBitmap(myBg, 0, 0, mPaint); } } finally { if (c != null) holder.unlockCanvasAndPost(c); } // Reschedule the next redraw mHandler.removeCallbacks(mDrawAnim); if (mVisible && mAnime) { mHandler.postDelayed(mDrawAnim, 50 ); } }

  • UI updates not happening in the expected order

    - by allonym
    I have a Panel which hosts a number of child controls in a grid layout. The child controls each consist of a Panel with a PictureBox and a Label. When one of these child controls is clicked it becomes "selected" (which basically entails changing its background to a different color) and an event is fired. In the handler for this event, an image is displayed in a PictureBox on a separate form. In code, the background of the child control is definitely changed before firing the event, but for some reason it never updates at runtime until after the image has updated in the other Form. I've tried to Invalidate() and Refresh() the child control before firing the event, without effect. Why is this happening, and what can I do to set it right?

  • Using Fancybox for country select in WordPress

    - by user2076774
    I am new to developing sites and just started using wordpress. I was told that I could use fancybox to help create a popup that would allow a person to select a country. Something similar to below, the only problem is I have no clue how to do this, I installed a fancybox plugin in (http://wordpress.org/plugins/fancybox-for-wordpress/). The way the person did it was you click on an image and then this text country pops up. How do I implement this to pop up a country select after you click on an image? Thanks!

  • 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!

  • Recommended Books for OpenGL [closed]

    - by TheBlueCat
    I'm fairly new to OpenGL and I'm have been researching any books that would be beneficial, I've had suggested to me (I've finished reading the OpenGL Book online): Real Time Rendering GPU Gems 3 OpenGL Super Bible Does anyone know any other books that they've found useful in the past, even if it covers higher level algorithms. Also, can anyone suggest an IDE/Text Editor for Linux? I'm using Komodo and it's super buggy, I just booted into Windows today and tried Visual Studio and loved it, is their anything similar for Linux? Although, the books I've been reading are saying to not use IDEs, partly because of the reliance you place onto them, per se. I use Eclipse a lot for my Java programming, can I use C and OpenGL with that? Lastly, do you think it would be more beneficial staying on Windows and programming in C/OpenGL on their, I do like Linux, but I found Visual Studio to be pretty good in some aspects?

  • Divs: Equal Horizontal Spacing

    - by Vecta
    I'm creating a site that has a series of four images on the homepage used as navigation with a large image beneath. <div style="width: 696px"> <div class="imglink"></div> <div class="imglink"></div> <div class="imglink"></div> <div class="imglink"></div> </div> <div style="width:696px"> ... </div> The "imglink" divs are 160px wide. I would like the images in the top div to be horizontally spaced evenly inside the div, with the two outer divs flush with the edges of the image below. I've been trying out floats, margins, padding, etc for a couple hours now and can't figure it out. Thanks for your help!

  • How to get the number of files in a folder as a variable?

    - by Jason
    Using bash, how can one get the number of files in a folder, excluding directories from a shell script without the interpreter complaining? With the help of a friend, I've tried $files=$(find ../ -maxdepth 1 -type f | sort -n) $num=$("ls -l" | "grep ^-" | "wc -l") which returns from the command line: ../1-prefix_blended_fused.jpg: No such file or directory ls -l : command not found grep ^-: command not found wc -l: command not found respectively. These commands work on the command line, but NOT with a bash script. Given a file filled with image files formatted like 1-pano.jpg, I want to grab all the images in the directory to get the largest numbered file to tack onto the next image being processed. Why the discrepancy?

  • Inconsistent behaviour from SDL_BlitSurface

    - by bardes
    Here is an example code: #include <SDL/SDL.h> #include <SDL/SDL_image.h> #include <stdio.h> int main() { if(SDL_Init(SDL_INIT_EVERYTHING) == -1) { printf("SDL ERROR: %s", SDL_GetError()); return 1; } SDL_Surface *screen; screen = SDL_SetVideoMode(128, 128, 32, SDL_SWSURFACE); SDL_Surface *img; img = IMG_Load("./debug.png"); SDL_BlitSurface(img, NULL, screen, NULL); SDL_Flip(screen); SDL_Delay(1000); SDL_FreeSurface(img); SDL_Quit(); return 0; } It compiles fine, but when I run it sometimes it works and most times only part of the image is displayed. I really can't imagine what's causing that... EDIT: This is the image I'm using to test the program: http://img140.imageshack.us/img140/3858/debugi.png

  • New line before header()

    - by MetalAdam
    I'm working with a custom made Joomla script that generates an image from a blob in a database. However, when we moved it from an Apache server to an IIS server, the script is breaking. Upon investigation, it seems that now, there is a line break that is getting appended before the header function is being run (when I comment out the image portion, and do an echo "test";, test gets printed on line 2 of the source code. I've gone through the script over and over again, and through the many files in the component, and can't seem to find out where this new line is coming from. At all. I've tried using ob_start() and many similar functions, but nothing seems to work. I'm completely out of ideas, and don't know where to turn. Is there a way to trace what files are being called in the page, perhaps? Any thoughts on further steps?

  • Windows Backup fails with 0x80070002: "The system cannot find the file specified"

    - by James Johnston
    Windows 7 Backup is failing. When backing up even a single insignificant directory (e.g. I chose only the empty "Contacts" directory, leaving all other directories unchecked), I get this error within a few seconds and the backup fails. If I uncheck all files/directories, and just do the system image - then the system image is backed up OK without issue. Backup destination is an external USB hard drive. Steps to reproduce and subsequent failure: Set up backup to go to external hard drive. Don't back up system image. Back up "Contacts" directory only for my profile. Start backup. Immediately view the status of the backup, it stays on "Creating a shadow copy..." for a few seconds, and then the backup fails. Click Options button, and it says "Check your backup / The system cannot find the file specified." - with options to "Try to run backup again" or "Change backup settings". If I click "Show Details", then it says: Backup time: 4/12/2012 04:38 Backup location: My Book (D:) Error code: 0x80070002 An examination of the Event Log shows nothing useful beyond the following: Log Name: Application Source: Windows Backup Date: 4/12/2012 04:38:44 Event ID: 4104 Task Category: None Level: Error Keywords: Classic User: N/A Computer: JTJLaptop Description: The backup was not successful. The error is: The system cannot find the file specified. (0x80070002). Event Xml: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Windows Backup" /> <EventID Qualifiers="0">4104</EventID> <Level>2</Level> <Task>0</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2012-04-12T04:38:44.000000000Z" /> <EventRecordID>23979</EventRecordID> <Channel>Application</Channel> <Computer>JTJLaptop</Computer> <Security /> </System> <EventData> <Data>The system cannot find the file specified.

Running SFC /SCANNOW to run system file checker Checked the list of profiles at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList and ensured that each profile directory exists. I'm stumped; WHAT file can't be found and why is my backup failing? This is on a Lenovo T420 laptop.
