  • PHP Magento Screen Scraping

    - by Grant unwin
    I am trying to scrape a suppliers magento site in an effort to save some time because of there being around 2000 products I need to gather info for. I'm totally OK with writing a screen scraper for pretty much anything but i've encountered a major problem. Im using get_file_contentsto gather the html of the product page. The problem is: You need to be logged in, to view the product page. Its a standard magento login, so how can I get round this in my screen scraper? I don't require a full script, just advice on a method. Thanks

  • Insert at specific location of a 2d vector

    - by Elgoog
    I have a 2d vector which represents a 2d grid; so grid[0][2] for example. I am needing to 'insert' -might not be the right word here. a vector at a specific location say grid[3][2] there will definitely be a grid[0][0] but when im needing to insert into grid[3][2] there may be nothing before it other than grid[0][0] and there needs to be the space in between for later on. Is there any way to do this? Thank you for your help. ps: I should note that the size of the vectors are not known (they will grow over time)

  • how to configure hibernate not to update @Version on each access to entity

    - by radai
    i have a simple query that returns an entity, and when i look at hibernate SQL output i see that when i execute this query hibernate updates the @Version field (on each consecutive read the @version field is updated). i dont modify anything in the entity i fetch, and i dont pass is as an argument to either persist or merge. this effectively means every read i make turns into a read+write. i've tried setting the lock mode t oboth NONE (jpa 2) and READ (jpa 1) to no avail. is there any way to achieve this? if so, is there any way to set this as the default behavior in persistence.xml in some way ? im using jpa2 over hibernate 3.6

  • Exposing console apps to the web with Ruby

    - by Aaron
    I'm looking to expose an interactive command line program via JSON or another RPC style service using Ruby. I've found a couple tricks to do this, but im missing something when redirecting the output and input. One method at least on linux is to redirect the stdin and stdout to a file then read and write to that file asynchronously with file reads and writes. Another method ive been trying after googling around was to use open4. Here is the code I wrote so far, but its getting stuck after reading a few lines from standard output. require "open4" include Open4 status = popen4("./srcds_run -console -game tf +map ctf_2fort -maxplayers 6") do |pid, stdin, stdout, stderr| puts "PID #{pid}" lines="" while (line=stdout.gets) lines+=line puts line end while (line=stderr.gets) lines+=line puts line end end Any help on this or some insight would be appreciated!

  • PHP speed optimisation.

    - by Petah
    Hi, Im wondering about speed optimization in PHP. I have a series of files that are requested every page load. On average there are 20 files. Each file must be read an parsed if they have changed. And this is excluding that standard files required for a web page (HTML, CSS, images, etc). EG - client requests page - server outputs html, css, images - server outputs dynamic content (20+/- files combined and minified). What would be the best way to serve these files as fast as possible?

  • Best way to update UI from other classes?

    - by Jack
    I've got several nested classes, with the following structure: BackupLocation contains list of BackupClients BackupClients contains a list of BackupVersions BackupVersions contains a list of BackupFiles In my UI - Im populating a combo box with BackupLocations - and have several listboxes for the clients, versions, and files. When processing the BackupLocations - I can update my status bar easily because thats the top level class that the UI creates. But how can I update the status bar and progress bar on each file being processed? Since the BackupFiles are 3 levels deep, I cant see any way to update the UI. The actual processing of the files are within the BackupVersion class - which loads its files. I think it probably has something to do with events and delegates - but am unsure exactly how to proceed with this, any help would be appreciated.

  • Communicate between service and winform

    - by Richard Tivey
    I could do with a bit of help with a windows service im writing in c#. The service basically just runs various tasks on a schedule. It has 3 main sections: a class which contains everything for the task (config, code to be executed when it runs, etc), the service which contains instances of the tasks, running them on a timer and a windows form which is used to configure the settings for the task. The question I have is would it be possible to reference the service from the Winform whilst the service is running? Ultimately I want to be able to open the Winform and see a live status of what the service is currently doing. I've considered writing something network related to get around it but it didn't seem correct considering that both processes would be on the same machine.

  • PHP Get Shape Coordinates From Points

    - by Ozzy
    Im sure if the title is exactly what I am trying to describe so sorry if it isnt. Ok here is what i am trying to do: What i want to do is create a function that you can enter unlimited ammount of coordinates ( the blue dots) and then it will create a shape like so and then return all coordinates the shape covers. Because this is for working with pixels, there will be no decimal coordinates. Something that can be used like so: print_r(get_coords(12,6, 23,13, 30,9, 37,24, 24,34, 25,24, 7,30, 6,15)); // ^ Will output an array of all x and y coordinates that the shape covers How would i go about doing something like this?

  • .NET Micro Edition - Open Multiple Windows

    - by RM
    I've had a look through quite a few tutorials, but cant seem to find how to open multipe windows? I'm not expecting to have them layer etc, I just want to define multiple window classes and say, from a menu, launch the appropriate window class from the menu window. Then when that window is finished, call the close method on it and menu will show again. I have managed to do the same kind of functionality using panels, but think window is really what I should be using? (.NET MF 4.0) I assume you can do this? I think im missing something obvious?

  • solutions for rapid front-end development?

    - by fayer
    im using mvc framework and i have learned some techniques that help me with different parts of RAD. models: doctrine/visual paradigm controllers/libraries: various design patterns now i only need to know what technique/solution i should use for the views so that i can create views more rapidly. cause i don't think it's efficient to code css/html manually, even though i understand it. its the same principle when using visual paradigm to create both my mysql database tables and doctrine model classes. i believe in using right tools will boost up development speed. so what could i use for the views to save time and energy and don't reinvent the wheel all the time? dreamweaver? any css generation tools? 960/blueprint for layout? suggestions? thanks

  • Javascript Library - Family Tree Flowchart

    - by MrMime
    Im looking for a simple Javascript Library (svg?) that allow me to draw a family tree relationships. I have searched a lot on google found a lot of interesting libraries like Raphaël and its extention Dracula. Google has its own library to make flowcharts too. Unfortunally, every library make a relation between nodes with a sigle line. If A and B has a relation to C, I will obtain 2 line: one from A to C and one from B to C. What I need is a line from A to B (we call it AB) and a line from AB to C to represent the Marriage of A and B. example-image Thanks.

  • python [lxml] - cleaning out html tags

    - by sadhu_
    from lxml.html.clean import clean_html, Cleaner def clean(text): try: cleaner = Cleaner(scripts=True, embedded=True, meta=True, page_structure=True, links=True, style=True, remove_tags = ['a', 'li', 'td']) print (len(cleaner.clean_html(text))- len(text)) return cleaner.clean_html(text) except: print 'Error in clean_html' print sys.exc_info() return text I put together the above (ugly) code as my initial forays into python land. I'm trying to use lxml cleaner to clean out a couple of html pages, so in the end i am just left with the text and nothing else - but try as i might, the above doesnt appear to work as such, i'm still left with a substial amount of markup (and it doesnt appear to be broken html), and particularly links, which aren't getting removed, despite the args i use in remove_tags and links=True any idea whats going on, perhaps im barking up the wrong tree with lxml ? i thought this was the way to go with html parsing in python?
