  • For loop to extract info from a structure doesn't work?

    - by ZaZu
    I have a structure in matlab that has a value of <1x1 struct>., its name is figurelist. Inside that structure, there is a field called images. Inside images, I have 25 images that have the name img1, img2, img3, ...... , img25. Now I made a for loop to extract those images, I basically did: For K=1:25 image(figurelist.images.imgK) PAUSE(0.25) End This unfortunately doesnt work. I get an error saying : ??? Reference to non-existent field 'imgK'. Is it possible to extract such info using a loop from a structure? Or am I doing something wrong? Thanks.

  • Agile web development with Rails 4 interface difficulties

    - by Luke Annison
    I've been following along with the examples in the book in making a online catalog and am having a couple of discouraging difficulties in Chapter 8 task C: Catalog display. I have input the code for the stylesheets as instructed but it has created a slightly skewed result as compared to what is shown in the book. Whilst minor and aesthetic in nature its a little shock to my confidence and slightly irritating when trying to carry on through the book. I have too little rep to post a pic, but heres the link: http://s11.postimage.org/3pwlzfiwj/Screen_Shot_2012_10_08_at_22_29_56.png) As you can see the boarder seems a little confused and the image at the top is covering the header text. I've been through the code time and time again but can't seem find out where I've gone wrong. Could anybody give me some clues?

  • Input-type-file path, where is it stored on AJAX request ?!?

    - by Sheavi
    Hi, I have been monitoring the parameters a website receives when a file is uploaded (via an input type="file"). Surprisingly, the parameter and its value were looking like this : parameter: upfile value: filename="this is the name of the uploaded file.png" Content-type: image/x-png Now in this POST request to the server page, the file name and its type is passed into a parameter, but what about the path to that filename? Where is that path stored so that the server page can upload the file at the good location? Also, I would like to know if it would be possible by any way to specify a path, NOT to the input type="file" since its impossible, but to the server (though this question probably depends a lot on how the server-side page is scripted). Thank you for your answers.

  • Comparing two images by corr2 function

    - by user3696860
    I'm trying to compare two images by corr2 function on Matlab, it's not necess getting 1 end of function so I am using a treshold to find best images among template images. But sometimes it evaluate wrong image. How can I process them to find best match? ` temp=[]; for i=1:10 res=sprintf('%d.png',i) yol=fullfile('cember\taslak_cember\',res); a=imread(yol); b=imread('30_1.png'); a=rgb2gray(a); b=rgb2gray(b); a=im2bw(a,0.4); b=im2bw(b,0.4); c=corr2(a,b); temp=[temp c]; end max(temp) `

  • Equal height divs with footer always at bottom of tallest div

    - by nukegara
    I was wondering if this were possible, and if it is the best way to go about this: example image (since I'm not allowed to post pics yet ^^) So, not only does each column have to be of equal height, but each column also has its own individual footer. I saw this post httx://stackoverflow.com/questions/1347366/div-at-bottom-of-window-and-adaptable-height-div (I also can't post more than one link....) - how could I rework this technique to apply to the bottom of the divs and not the bottom of the window? *edit - each column will have content that will constantly change and be of variable height. I'm thinking I could just figure out the equal height columns first, then just absolute position a footer div within those columns. Does its parent div then have to be position: relative?

  • How to add response headers based on Content-type; getting Content-type before the response is commi

    - by Bozho
    I want to set the Expires header for all image/* and text/css. I'm doing this in a Filter. However: before calling chain.doFilter(..) the Content-type is not yet "realized" after calling chain.doFilter(..) the Content-type is set, but so is content-length, which forbids adding new headers (at least in Tomcat implementation) I can use the extensions of the requested resource, but since some of the css files are generated by richfaces by taking them from inside jar-files, the name of the file isn't x.css, but is /xx/yy/zz.xcss/DATB/.... So, is there a way to get the Content-type before the response is committed.

  • Is it possible to hide the cursor in a webpage using CSS or Javascript?

    - by yeyeyerman
    I want to hide the cursor when showing a webpage that is meant to display information in a building hall. It doesn't have to be interactive at all. I tried with the cursor property and a transparent cursor image but I didn't make it work. Does anybody know if this can be done? I suppose this can be thought as a security threat for a user that can't know where he is clicking on, so I'm not very optimistic... Thank you!

  • Making dynamic images have static filenames

    - by michaeltk
    My website currently has various links to a php script that generates the images dynamically. For example, the link may say "img source="/dynamic_images.php?type=pie-chart&color=red" Obviously, this is not great for SEO. I'd like to somehow make the filenames of these links appear to be static, and use a solution (like Mod-Rewrite) to ensure that the images can still be dynamically created. I suppose I could have something like "img src="average-profits-in-scuba-diving-industry.png?type=pie-chart&color=red" (and use Mod-Rewrite to take care of changing the filename prefix to dynamic_images.php), but I'm afraid that the search engines would shy away from the querystring on the end of the image filename. Any solutions? Thanks in advance.

  • Firing a Keyboard Event at the Body - JavaScript (?)

    - by user317985
    I've done a lot of research on this but have come up empty handed. What I would like to do is invoke or create an event for the right arrow key (Key Code 39). I was planning on using an onclick event inside an tag to go to a function where this event could be 'fired'. Any help would be appreciated. If anyone needs context, I have a jQuery content slider that's functionality is very hard to alter and currently the functionality I need to emulate only occurs when a user hits the right arrow on their keyboard. What I would like to do is tie an onclick() event to a image that when clicked on fires the right keyboard event and the content will slide. Please let me know if I can provide further details or explanation. My working demo for this is: http://greenplanet3d.com

  • Ruby on Rails ActiveScaffold: Showing {{model}} instead of model name?

    - by AnExtremelySmellyPerson
    Hi there, I'm using ActiveScaffold with Ruby on Rails and I'm loving it, however there is one weird thing. Whenever I hit "Edit" or "Create New" in my webapp's ActiveScaffold, it says "Create {{model}}" or "Update {{model}}" in the webapp rather than using the model's name. Why is this? I have an ads_controller.rb that includes this: active_scaffold :ad do |config| config.label = "Ads" config.columns = [:name, :description, :imageUrl, :linkUrl, :apps, :created_at, :updated_at] config.update.columns = [:name, :description, :imageUrl, :linkUrl, :apps] config.create.columns = config.update.columns list.sorting = {:created_at => 'DESC'} columns[:imageUrl].label = "Image URL" columns[:linkUrl].label = "Link URL" end And my routes.rb includes this: map.namespace :admin do |admin| admin.root :controller => 'admin_home', :action => 'index' admin.resources :ads, :active_scaffold => true end Any thoughts on why I'm seeing "Create {{model}}" instead of "Create ad" ?

  • jQuery pagination go to page on input value change

    - by JV10
    I'm creating some pagination for my website, and want to use an input-element to navigate between pages. Like the following example: The input would require the "return" key to be hit for the script to trigger. If the value entered is not within range and alert would trigger. e.g. If there was 32 pages, "Please enter a value between 1 and 32" Can this be done using jQuery or javascript, by detecting the value change within the range of pages and redirecting to that page? I'm trying to create the same device on Getty Images: http://www.gettyimages.com.au/Search/Search.aspx?contractUrl=2&language=en-US&family=creative&p=ball&assetType=image&clarification=ball%3A60847

  • input URL, output contents of "view page source", i.e. after javascript / etc, library or command-li

    - by Ryan Berckmans
    I need a scalable, automated, method of dumping the contents of "view page source" (DOM) to a file. Programs such as wget or curl will non-interactively retrieve a set of URLs, but do not execute javascript or any of that 'fancy stuff'. My ideal solution looks like any of the following (fantasy solutions): cat urls.txt | google-chrome --quiet --no-gui \ --output-sources-directory=~/urls-source (fantasy command line, no idea if flags like these exist) or cat urls.txt | python -c "import some-library; \ ... use some-library to process urls.txt ; output sources to ~/urls-source" As a secondary concern, I also need: dump all included javascript source to file (a la firebug) dump pdf/image of page to file (print to file)

  • Creating a Dynamic calendar in Silverlight

    - by Tom
    I am attempting to create a long range calendar that dynamically loads (and unloads) event data as the user scrolls left or right through time. I'm really struggling to figure out how to lay the basic framework of the UI out and how to dynamically build the interface as the user scrolls by clicking and dragging the mouse in the view area. See the image below for a basic diagram of the intent. Each slice would have potentially multiple rectangles in it for events that occurred on that day (slice). I would like each slice to be a canvas to allow me to position those rectangles appropriately. There are a few problems that I am not yet sure how to tackle but this is the first big one that I've been mulling over for a while and can't quite wrap my head around: I know how to dynamically create controls but how would I go about adding things to one end of the scrollable content while removing things from the other depending on the way the user is scrolling? Any guidance in the right direction would be much appreciated! Thanks.

  • Best way to fix an out-of-sync TFS workspace after a back-up/restore

    - by DanO
    Wednesday I had to restore from a back-up image I made on Monday. At the time of the snapshot I had about 20 files modified, which I later checked in, and more, on Tuesday. Now that I am back to a snapshot from Monday morning, my workspace has all of these files checked-out or added, etc. even my check-in comments and work-item associations. But I already did that check-in on Tuesday. I'm thinking I will shelve all the pending changes (just in-case), and then just undo all changes, and get latest (specific version). And I should be back to good. Any cautions or suggestions? (TFS 2008, VS2010)

  • matplotlib 3D plot with PyQt4 in Qtabwidget (mplwidget)

    - by artdijk
    I am working on my first Python app using PythonXY (2.6 and Qt4). I have a window with some buttons and a QtabWidget. When I press a button I want to plot a 3D image on a specific tab. I managed to get a 2D plot but I can't get the axes to 3D. Via Qt desiger I use the mplwidget. In many examples I see the use of figure(), but I can't get that to work with the mplwidget. (I am not sure if that is even possible) Can you please show me an example of code defining the 3D axes (in a QtabWidget) with a simple plot ? Thanks very much

  • How to match data between columns to do the comparasion

    - by NCC
    I do not really know how to explain this in a clear manner. Please see attached image I have a table with 4 different columns, 2 are identical to each other (NAME and QTY). The goal is to compare the differences between the QTY, however, in order to do it. I must: 1. sort the data 2. match the data item by item This is not a big deal with small table but with 10 thousand rows, it takes me a few days to do it. Pleas help me, I appreciate. My logic is: 1. Sorted the first two columns (NAME and QTY) 2. For each value of second two columns (NAME and QTY), check if it match with first two column. If true, the insert the value. 3. For values are not matched, insert to new rows with offset from the rows that are in first two columns but not in second two columns

  • Using UIImageViews for 'pages' in an iPhone/iPad storybook app?

    - by outtoplayinc
    I'm new to iPhone programming, and well, what seems obvious to me may seem silly to a seasoned coder. I did a few 'switching views' tutorials on Youtube, and basically, they seems to work nicely for adding pages to a storybook type app. You add a UIViewController and associated view for each page. My question is would this become insanely slow, or a memory hog if I continued this method for say....35+ pages? Each page would also have a sound file associated with it that would play narration when a page load and stops when we leave. Basically, think of a powerpoint type app, with sound, possibly animated image elements, next & back buttons. I'm probably thinking of this very simplistically, but that's where my experience is at for the moment. Any insight or tips as to better and or more efficient ways to proceed would be greatly appreciated.

  • Could not retrieve data from URL

    - by user1655065
    I have a lot of websites which are using the same CMS, and they are hosted in 3 seperated servers, only one of this servers has a problem with retrieving the title, description, and the image of any url, and in the FaceBook debugger I get this error: Could not retrieve data from URL. From previous questions, I read that the reason may be an HTML error, but as I said before on other servers there is no problem using the same CMS. You can try putting this URL for example in the debugger: http://www.shaharah.net/2010/news-10054.htm Also, other websites on the same server which are using another CMS, or is just HTML pages are also not retrieved. Thanks. Best regards, Aws Aleryani

  • conceptually different entities with a few similar properties should be stored in one table or more?

    - by Haghpanah
    Assume A and B are conceptually different entities that have a few similar properties and of course their own specific properties. In database design, should I put those two entities in one big aggregated table or two respectively designed tables. For instance, I have two types of payment; Online-payment and Manual-payment with following definition, TABLE [OnlinePayments] ( [ID] [uniqueidentifier], [UserID] [uniqueidentifier], [TrackingCode] [nvarchar](32), [ReferingCode] [nvarchar](32), [BankingAccID] [uniqueidentifier], [Status] [int], [Amount] [money], [Comments] [nvarchar](768), [CreatedAt] [datetime], [ShopingCartID] [uniqueidentifier], ) And TABLE [ManualPayments] ( [ID] [uniqueidentifier], [UserID] [uniqueidentifier], [BankingAccID] [uniqueidentifier], [BankingOrgID] [uniqueidentifier], [BranchName] [nvarchar](64), [BranchCode] [nvarchar](16), [Amount] [money], [SlipNumber] [nvarchar](64), [SlipImage] [image], [PaidAt] [datetime], [Comments] [nvarchar](768), [CreatedAt] [datetime], [IsApproved] [bit], [ApprovedByID] [uniqueidentifier], ) One of my friends told me that creating two distinct tables for such similar entities is not a well design method and they should be put in one single table for the sake of performance and ease of data manipulations. I’m now wondering what to do? What is the best practice in such a case?

  • PHP - MySQL - Select runs indefinitely

    - by John
    I have three tables listings: id, pid, beds, baths, etc, etc, etc, db locations: id, pid, zip, lat, lon, etc, etc, etc, db images id, pid, height, width, raw, etc, etc, db id, pid & db are indexed. db just references the mls provider a particular item came from. in images the raw column holds raw image data there are about 15k rows in listings/locations, and about 120k rows in images so there are multiple rows that have the same pid. when i do "select pid from listings" or "select pid from locations" the query completes successfully in about 100ms. when i do "select pid from images" it just hangs in sqlyog and never completes... i was thinking since the raw column contains alot of information that it might be trying to select that too, but my query doesn't try to select that so I can't imagine why it's taking so long... any idea why this is happening??
