• Learn C++ after learning C#

  - by RichK

  I'm developing a library in C# at the moment and recently bought a great book to help me out but the code snippets are in C++. Does anyone have a link to a site/PDF that'll give me a crash course in C++? (mainly the syntax rather than pros/cons etc) because I'll be developing in C# but things like -, ::, &, **, are giving me the shivers. Obviously the languages aren't 100% compatible but if I know what the C++ is doing from a 'theoretical' point of view I can make a stab at rewriting it in C#. I've had a Google to find the answer but all the sites seem to be "Should I use C++ or C#?", which isn't any good to me. Thanks in advance.

• Cascading MVC controllers with CatchAll Routes

  - by Richard

  Hi, I have an MVC app which has its routes defined with the final route being a catch all route to a "PageController" for a database driven collection of pages. What I want to achieve is to be able to plugin to the app a second controller to the catch all route which the first controller passes on to if it does not find the url recieved in the database. Effectively I want to queue up controllers with catch all actions: public ActionResult PageCatchall(string url) { var page = repository.Get<Page>(string url); if (page != null) { // Handle the request return View(page) } // Otherwise pass to a new controller ???? } Anyone have any good ideas as to how to solve this? I have tried RedirectToAction but that requires that the next controller has a different route to the action. I have tried ActionInvoker but this failed to work the way I did it.

• Find node level in a tree

  - by Álvaro G. Vicario

  I have a tree (nested categories) stored as follows: CREATE TABLE `category` ( `category_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `category_name` varchar(100) NOT NULL, `parent_id` int(10) unsigned DEFAULT NULL, PRIMARY KEY (`category_id`), UNIQUE KEY `category_name_UNIQUE` (`category_name`,`parent_id`), KEY `fk_category_category1` (`parent_id`,`category_id`), CONSTRAINT `fk_category_category1` FOREIGN KEY (`parent_id`) REFERENCES `category` (`category_id`) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_spanish_ci I need to feed my client-side language (PHP) with node information (child+parent) so it can build the tree in memory. I can tweak my PHP code but I think the operation would be way simpler if I could just retrieve the rows in such an order that all parents come before their children. I could do that if I knew the level for each node: SELECT category_id, category_name, parent_id FROM category ORDER BY level -- No `level` column so far :( Can you think of a way (view, stored routine or whatever...) to calculate the node level? I guess it's okay if it's not real-time and I need to recalculate it on node modification.

• How to use php variables (arrays) in mysql select statements?

  - by davidconn

  Hi everybody, How do you use a php variable (array) inside a mysql select statement? I am designing an auction site and currently working on a page that lets people view a list of all the current bids for an item. I want to display 3 columns: amountbid - the amount each bidder has bid for the item (held in tblbid) bidderid - the id of each bidder who has bid (found in tbluser) total_positivity_feedback - how many users have left positive feedback for the bidder (calculated from tblfeedback) To find the 'amount' and the 'bidderid' columns i pass the essayid URL parameter from the previous page. This works fine. Despite this, i can't display the total_positivity_feedback column for the various users who have made each bid. My mysql query looks like this: select tblbid.bidderid, tblbid.amount, (select count(tblfeedback.feedbackid) from tblfeedback WHERE tblfeedback.writerid = "ARRAY VARIABLE GOES HERE") AS total_positivity_feedback FROM tblbid WHERE tblbid.essayid = $essayid_bids I assume that the only way to accomplish this is to make the variable contain the bidderid's of those people who bid for that particular essay? I can't seem to work out how to do this tho?!? Many thanks for your help

• MediaWiki: workaround for watchlist restricted to 7 days?

  - by Mark Robinson

  I'm running MediaWiki 1.13.2. When I go to my watchlist, I'm limited to only viewing the last 7 days (though MediaWiki should permit me to view the last 30 days). I've tried: Clicking the all button Changing the URL Changing the settings under MY PREFERENCES-WATCHLIST. When I save (e.g. 30 days) it resets back to 7 days! Googling for an answer... Anyone heard of this bug before? Is there a workaround? I can't see a setting anywhere for this to be a maximum.

• How to access Oracle system tables from inside of a PL/SQL function or procedure?

  - by mjumbewu

  I am trying to access information from an Oracle meta-data table from within a function. For example (purposefully simplified): CREATE OR REPLACE PROCEDURE MyProcedure IS users_datafile_path VARCHAR2(100); BEGIN SELECT file_name INTO users_datafile_path FROM dba_data_files WHERE tablespace_name='USERS' AND rownum=1; END MyProcedure; / When I try to execute this command in an sqlplus process, I get the following errors: LINE/COL ERROR -------- ----------------------------------------------------------------- 5/5 PL/SQL: SQL Statement ignored 6/12 PL/SQL: ORA-00942: table or view does not exist I know the user has access to the table, because when I execute the following command from the same sqlplus process, it displays the expected information: SELECT file_name FROM dba_data_files WHERE tablespace_name='USERS' AND rownum=1; Which results in: FILE_NAME -------------------------------------------------------------------------------- /usr/lib/oracle/xe/oradata/XE/users.dbf Is there something I need to do differently?

• Wordpress & Vanity User URLs

  - by st4ck0v3rfl0w

  Hi All, Was wondering if anyone had any smart approaches to creating dynamic vanity user urls upon user registration. My site basically uses emails as usernames. I have the regex to strip the text before the "@" symbol (e.g. "[email protected]" becomes "name") I would then like to take the "name" and create a vanity url (e.g. domain.com/name or name.domain.com) Any thoughts on how to accomplish this with Wordpress? I'm a pretty advanced Wordpress user and my first thoughts were to do the following Verify user registration Upon successful user registration create page name with username as the title (this would help me achieve the www.domain.com/username) Apply preset template to that page with the desired view Any and all thoughts are welcome.

• Why isn't a JS file hosted on Amazon S3 getting cached by the browser?

  - by Paras Chopra

  I have a JS file hosted on Amazon S3 (http://s3.amazonaws.com/wingify/vis_opt.js). I want the file to be cached on users' browsers so that they don't have to download it with every page view. However, in spite of setting Cache Control header I don't think it is getting cached. Browser still contacts Amazon Server with every pageview. Here is the example of page where this script is embedded: http://myjugaad.in/ If you have Firebug, you will be able to see that browser requests it with every pageview. What can I do so that the file gets permanently cached? Thanks for help.

• How to track conversion rate (clicks to sales) from an internal advertising system?

  - by Ed Woodcock

  I am currently writing an interal advertising system for a company client's website, where the adverts will only be seen by internal users, and all transactions take place internally to the site (i.e. the adverts are for member-only content available on the site). Does anyone have any recommendations as to the best way to track the conversion rate of these adverts (i.e. views:clicks:sales)? EDIT I'm not looking for a 'Why don't you use google analystics'-type answer, I'm looking into possible architecture outlines, i.e. a 'why don't use store a guid in a cache temporarily and see if it ties to the advert' kind of answer. /EDIT In a previous job I did something based on an internal cache, which simply did view:click tracking, however the addition of the sales rate makes this task more complex, especially if we take into account the idea that someone may click through to an advert and not purchase immediately. Cheers, Ed (N.B. I'm leaving this purposely vague in order to (hopefully) get some answers that provide ideas I've yet to have thought of by coming at the problem from a different angle)

OnTreeNodePopulate event fires this event, protected void tvLabs_TreeNodePopulate(object sender, System.Web.UI.WebControls.TreeNodeEventArgs e) { PopulateSubLevelLab(e.Node.Value, e.Node); //This function is used for populating the child node. FillLabGrid(e.Node.Value);---My Question? } ---My Question? The FillLabGrid method used for fill a grid view on the basis of selecting the treeview parent node. But this function filled the grid only once when i click the parent node for the first time.

• IB z-order on simulator 6.0

  - by Stanley

  Consider the above's IB objects listing. Siblings further down the list should be on top of the siblings listed further up when rendered on the screen. Under Xcode 4.5.2, everything is ok if iphone simulator 5.1 is used. But for simulator 6.0 the map just covers everything. The same if using actual devices (phones) for testing. Hope that somebody knowledgeable could help. Please also add comments if you do not find such a problem on simulator 6.0. Because chances are the problem is related to how my project is setup. Update : Have setup a test project with the iOS 6 map view. There seems to be no problem with the z-order. So the problem should relate to my code.

• What exactly is GRASP's Controller about?

  - by devoured elysium

  What is the idea behind Grasp's Controller pattern? My current interpretation is that sometimes you want to achieve something that needs to use a couple of classes but none of those classes could or has access to the information needed to do it, so you create a new class that does the job, having references to all the needed classes(this is, could be the information expert). Is this a correct view of what Grasp's Controller is about? Generally when googling or SO'ing controller, I just get results about MVC's (and whatnot) which are topics that I don't understand about, so I'd like answers that don't assume I know ASP.NET's MVC or something :( Thanks

• How to structure data... Sequential or Hierarchical?

  - by Ryan

  I'm going through the exercise of building a CMS that will organize a lot of the common documents that my employer generates each time we get a new sales order. Each new sales order gets a 5 digit number (12222,12223,122224, etc...) but internally we have applied a hierarchy to these numbers: + 121XX |--01 |--02 + 122XX |--22 |--23 |--24 In my table for sales orders, is it better to use the 5 digital number as an ID and populate up or would it be better to use the hierarchical structure that we use when referring to jobs in regular conversation? The only benefit to not populating sequentially seems to be formatting the data later on in my view, but that doesn't sound like a good enough reason to go through the extra work. Thanks

• iPad: How can I implement a scrolling timeline using a static image?

  - by BeachRunnerJoe

  I'm diving into iOS development and I'm building a simple timeline app using a static timeline image that I already have. The timeline image won't fit on the screen. The width of the image is about five times the width of the iPad screen, so I have to allow the user to scroll the image horizontally. Here's a mockup... For each item on the timeline, the user can tap it to receive a description at the bottom of the screen. My questions are... I was planning to use a UIScrollView with a PageControl at the bottom. Can a UIScrollView hold a single view that holds the entire timeline image or do I have to break the the timeline image up into multiple views? Are there any performance issues I need to consider when implementing this with a UIScrolLView, using a static image? Are there other approaches to implementing this scrollable timeline that I should consider other than using a UIScrollView? Thanks so much in advance for your wisdom!

• Django forms: prepopulate form with request.user and url parameter

  - by Malyo

  I'm building simple Course Management App. I want Users to sign up for Course. Here's sign up model: class CourseMembers(models.Model): student = models.ForeignKey(Student) course = models.ForeignKey(Course) def __unicode__(self): return unicode(self.student) Student model is extended User model - I'd like to fill the form with request.user. In Course model most important is course_id, which i'm passing into view throught URL parameter (for example http://127.0.0.1:8000/courses/course/1/). What i want to achieve, is to generate 'invisible' (so user can't change the inserted data) form with just input, but containing request.user and course_id parameter.

• Resizing the imageView in a UITableView

  - by Luca

  Hi! I Created a grouped table view, and I noticed that placing an image in the imageView results in an image that is too large. It overlaps the rounded borders of the cell, which is horrible. I tried looking for a way to resize it, but I found many answers that didn't quite satisfy me. How would you do this? Which is the simplest way to go? The solutions I found where strangely complicated. Thanks!

• asp.net could a half submitted web page be processed?

  - by c00ke

  Having a weird bug in production and just wondering if it's possible for a half submitted web page to processed by the server? The page has no view state just using plain old html controls and accessing data displayed in repeater on the back end via Request.Form[name] etc. Is it possible for a request to be truncated perhaps due to lost internet connection and the page still processed by the server. Therefore if field not part of the request Request.Form[name] could result in null? I know can use fiddler to modify request but unfortunately we are not allowed to change group policy and change the proxy! Many Thanks

• Cannot call struct properties from HAML file

  - by Lander

  I have the following code in my controller: @nav_items = ActiveSupport::OrderedHash.new @nav_items[:home] = Struct::NavItem.new("Home", nil, "/", "icon-home") @nav_items[:about] = Struct::NavItem.new("About", nil, "/about", "icon-heart") @nav_items[:contact] = Struct::NavItem.new("Contact", nil, "/contact", "icon-envelope") if (current_user != nil && current_user.admin?) @nav_items[:admin_divider] = Struct::NavItem.new(nil, "divider-vertical", nil, nil) @nav_items[:admin] = Struct::NavItem.new("Admin", nil, "/admin", "") end And the following in my view: - @nav_items.each do |nav_item| %li{ :class => nav_item[:class] } %a{ :href => nav_item[:link] }= nav_item[:text] And my struct definition: Struct.new("NavItem", :text, :class, :link, :icon_class) I'm relatively new to Ruby, Rails, and HAML, but in another project using ERB rendering, code like that worked fine. I've tried referencing properties by doing something like nav_item.link as well, but that still does not work. The error I get with my current code is: Symbol as array index By using code like nav_item.link: undefined method `link' for #< Array:0x126970ff0 As this is my first time using HAML, I'm not too sure what I'm doing wrong.

• IE7 jQuery(document).ready() problem

  - by Zendog74

  I have a page that works perfectly fine in Firefox, but is throwing an error in IE. I am loading jQuery dynamically (if it is not already loaded), and then doing some stuff in the jQuery(document).ready() block. However, IE throws the dreaded "Object expected" error when it hits the jQuery(document).ready() block. You can view the full page code here: http://www.pastie.org/977767 IE is throwing the error right at jQuery(document).ready(). Any ideas as to what is going here? Again, this works perfectly fine in Firefox. It seems almost like IE thinks jQuery is loaded but it really isn't yet or that jQuery is still loading when the jQuery(document).ready() block is encountered?

• Why I cant be able to change the UITableViewCell detailTextLabel's frame (just the label's position)?

  Hi.. I am having a table view with default UITableViewCell of style UITableViewCellStyleValue2. I just want to move detailTextLabel few pixels to the right. I know it makes no sense to adjust its width and height :). I am trying to set detailTextLabel's frame with my x and y value. But its not affecting the its frame. I prefer to use default UITableViewCell, in this case, over a customized cell because the default UITableViewCell automatically manages the text alignment and centering of the labels.. How to change UITableViewCell detailTextLabel's frame? Am I allowed to change its frame? Thanks everyone..

• CMS or roll-yer-own?

  - by girlwithglasses

  I have a database of software tools and I want to be able to have users rate and comment on the tools, and view the ratings and comments that other users have left. To lower the risk of spammers attacking the site, I would like to be able to restrict comment/rating permissions to those who are logged in. At present, the tools are in a list on a static html page as part of a website that is very "non-interactive"; other than the contact form, there is nowhere that users contribute content to the site. We maintain a wiki (of the standard mediawiki flavour) that users can contribute to, and we also have a Drupal installation as a news site. Does anyone have any experience of creating such a rating/commenting system, and whether it would be better to use Mediawiki or Drupal (or another free CMS?), or to try to create something myself? Any advice would be appreciated. Thanks!
