• How do i get visual studio like tabs?

  - by Skun

  Hi guys. I've had this thought for a long time in my head now and i've not been able to find the solution to it ! Please help me. I've always loved the visual studio tabs and how they look. They're small and perfect. The normal TabControl, well is -bleh- and boring ! And i've seen these tabs being used in many applications .. so, my Question is this: Is that like a DLL that is available out there that i can link in order to get this control ? For all those who are wondering what tabs i'm talking about, feel free to check out the image below

• filter queryset based on list, including None

  - by jujule

  Hi all I dont know if its a django bug or a feature but i have a strange ORM behaviour with MySQL. class Status(models.Model): name = models.CharField(max_length = 50) class Article(models.Model) status = models.ForeignKey(status, blank = True, null=True) filters = Q(status__in =[0, 1,2] ) | Q(status=None) items = Article.objects.filter(filters) this returns Article items but some have other status than requested [0,1,2,None] looking at the sql query : SELECT [..] FROM `app_article` LEFT OUTER JOIN `app_status` ON (`app_article`.`status_id` = `app_status`.`id`) WHERE (`app_article`.`status_id` IN (1, 2) OR `app_status`.`id` IS NULL) ORDER BY [...] the OR app_status.id IS NULL part seems to be the cause. if i change it to OR app_article.status_id IS NULL it works correctly. How to deal with this ? Thanx.

• Drupal: what's the easiest way to let my customer to upload video thumbnails and associate them to v

  - by Patrick

  hi, my customer wants a gallery of videos and images (small thumbnails) and if you click on one of them you can see the picture / video in the overlaying lightbox). Now, I cannot install auto-generating video thumbnails because I don't have access to ffmpeg module on the server. I can only allow my customer to upload these thumbnails by himself. I'm using image and video CCK fields for each node to allow my customer images and videos. However I dunno how should I let him upload thumbnails for his videos. Should I create an additional Image CCK field for this ? Consequently, I should somehow associate the videos with the images in the design and my customer should pay attention to place them in the same order.. this is not very nice solution, but it is the only one that came to my mind so far. Furthermore, I'm using the lightbox I should somehow ignore the video thumbnails and display the videos instead... some tips ? Thanks

• Left outer joins that don't return all the rows from T1

  - by Summer

  Left outer joins should return at least one row from the T1 table if it matches the conditions. But what if the left outer join performs a join successfully, then finds that another criterion is not satisfied? Is there a way to get the query to return a row with T1 values and T2 values set to NULL? Here's the specific query, in which I'm trying to return a list of candidates, and the user's support for those candidates IF such support exists. SELECT c.id, c.name, s.support FROM candidates c LEFT JOIN support s on s.candidate_id = c.id WHERE c.office_id = 5059 AND c.election_id = 92 AND (s.user_id = 2 OR s.user_id IS NULL) --This line seems like the problem ORDER BY c.last_name, c.name The query joins the candidates and support table, but finds that it's a different user who supported this candidate (user_id=3, say). Then the candidate disappears entirely from the result set.

• User Interface. Multiple select with priority.

  - by Andrew Florko

  I'm designing user interface and want to ask your advises how to make it more user-friendly. Please tell any suggestions and if you have ever seen implementation of something familiar please share the link. University. There are 40+ specialities grouped into 5 faculties. User choose several he is interested in and than orders them by priority. For example I am interested in "programming microcontrollers", "system analysis" and "experimental physic". I must find them quickly in "programming faculty", select them and then order - what I prefer most and what I prefer less then others I select. Any ideas welcome :)

• Problems loading controller from url with codeigniter?

  - by Cody Short

  I'm currently in the process of putting up my first website for public use. I am using the codeigniter framework in order to do this, but I am having trouble loading the controllers from the url. I currently have the default codeigniter installment that you download trying to get things to work. The controller welcome is loaded by default, but when I try to load it through the url it doesn't work. I was having the same problem with the site that I had uploaded earlier. The site is located at this link any help on this would be appreciated.

• C++ Vector at/[] operator speed

  - by sub

  In order to give functions the option to modify the vector I can't do curr = myvec.at( i ); doThis( curr ); doThat( curr ); doStuffWith( curr ); But I have to do: doThis( myvec.at( i ) ); doThat( myvec.at( i ) ); doStuffWith( myvec.at( i ) ); (as the answers of my other question pointed out) I'm going to make a hell lot of calls to myvec.at() then. How fast is it, compared to the first example using a variable to store the result? Is there a different option for me? Can I somehow use pointers? When it's getting serious there will be thousands of calls to myvec.at() per second. So every little performance-eater is important.

• jQuery/CSS related problem

  - by MrAwesome

  Hi I am new to jQuery, and this is the page I'm currently developing. http://90.230.237.71/gandhi.html (Hope that works now :P) When I hit "Show/hide gallery" all the images are first opened vertically, and later they are corrected to their horizontal placement, that's the problem. They should be horizontal right away! I don't know if this is due to jQuerys slideDown or entirely CSS-related, but the code is all there for you. Initally, the images are set to display: none, perhaps they then are invisibly stored vertically. Then slideDown is performed and last, the CSS-attributes are changed to "display: inline". Perhaps I need to change execution order of slideDown and setting the CSS-attributes... but how? I NEED HELP... for many reasons, but I only want you to help me with this one ;) And also, please actually look at the code before making any assumptions. It's all there in the code.

• How to organize Windows Phone code base to target both 7.x and 8 platforms

  - by ljubomir

  I took over a Windows Phone project which was previously targeting WP 7.1 platform, and with the recent announcement of the new platform it should target WP 8 as well. My VS 2010 solution consists on several projects (Data access, Model, Tests and WP7 client app) and i am wandering on how to include support for WP8. I have to note that the code-base is not compatible with WP8, due to usage of Toolkit controls and other 3rd party libraries targeted for WP7.1 specifically. Also there is another problem with the Visual Studio versions - WP7.1 can work with VS 2010, but WP8 requires VS 2012. Should i move the whole code-base to VS 2012? Any good advice on how to organize code-base in a most meaningful way in order to avoid duplication and possible painful maintenance? I am thinking between one solution - multiple projects vs. multiple solutions - reusable projects approach. Code duplication (like two separate folders/solutions) should be the least possible approach (fallback).

• PHP PDO - bindValue PARAM_BOOL as string

  - by PHP_guy

  I'm freaking out here and can't figure out what's wrong. I'm pretty new to PDO, but everything works in my code except for booleans which are sent as strings. My code (simplified): $sql = 'SELECT * FROM pages WHERE clean_url_slo = :clean_url_slo AND published = :published LIMIT 1'; $clean_url_slo = 'home'; $published = true; Then I prepare stuff and execute it like this (simplified): $stmt = $db->prepare($sql); $stmt->bindValue(':clean_url_slo',$clean_url_slo,PDO::PARAM_STR); $stmt->bindValue(':published',$published,PDO::PARAM_BOOL); $stmt->execute(); And then here is what comes to mysql (from the mysql log - the query mysql received): 91 Query SELECT * FROM pages WHERE 1=1 AND clean_url_slo='domov' AND published='1' ORDER BY id desc LIMIT 1 As you can see, published is an integer - so always true, which is not OK. Why is that if I'm declaring it as a boolean? using: WAMP SERVER PHP version: 5.3.9 Mysql: 5.5.20 Many thanks for your help..

• Joining two select queries and ordering results

  - by user1

  Basically I'm just unsure as to why this query is failing to execute: (SELECT replies.reply_post, replies.reply_content, replies.reply_date AS d, members.username FROM (replies) AS a INNER JOIN members ON replies.reply_by = members.id) UNION (SELECT posts.post_id, posts.post_title, posts.post_date AS d, members.username FROM (posts) as b WHERE posts.post_set = 0 INNER JOIN members ON posts.post_by = members.id) ORDER BY d DESC LIMIT 5 I'm getting this error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'a INNER JOIN members ON replies.re' at line 2 All I'm trying to do is select the 5 most recent rows (dates) from these two tables. I've tried Join, union etc and I've seen numerous queries where people have put another query after the FROM statement and that just makes no logical sense to me as to how that works? Am I safe to say that you can join the same table from two different but joined queries? Or am I taking completely the wrong approach, because frankly I can't seem see how this query is failing despite reading the error message. (The two queries on there own work fine)

• Return multiple results using dynamic sql (postgresql 8.2)

  I want to loop through schemas and get a result set that looks like this: Count 5 834 345 34 984 However, I can't get it to return anything using dynamic sql...I've tried everything but 8.2 is being a real pain.

• How do manage the limit of executions to be done by hour (Max: 1000 requests per hour) without a dat

  - by cslavoie

  I am currently developing a script in PHP to fetch webpages. The fact is that by doing so, I occasionally do too much requests to a particular website. In order to control any overflow, I would like to keep trace of how many requests have been done in the last hour or so for each domain. It doesn't need to be perfect, just a good estimate. I doesn't have access to a database, except sqlite2. I would really like something really simple because there will typically be a lot of updates, which is kind of heavy for a sqlite database. If no one has a magical solution, I'll go for sqlite, but I was curious what you can come up with Thank you very much

• Annotation based data structure visualization - are there similar tools out there?

  - by Helper Method

  For a project at university I plan to build an annotation based tool to visualize/play around with data structures. Here's my idea: Students which want to try out their self-written data structures need to: mark the type of their data structures using some sort of marker annotation e.g. @List public class MyList { ... } so that I know how to represent the data structure need to provide an iterator so that I can retrieve the elements in the right order need to annotate methods for insertion and removal, e.g. @add public boolean insert(E e) { ... } so that I can "bind" that method to some button. Do similar applications exist? I googled a little bit around but didn't find anything like that.

• Simple Big O with lg(n) proof

  - by halohunter

  I'm attempting to guess and prove the Big O for: f(n) = n^3 - 7n^2 + nlg(n) + 10 I guess that big O is n^3 as it is the term with the largest order of growth However, I'm having trouble proving it. My unsuccesful attempt follows: f(n) <= cg(n) f(n) <= n^3 - 7n^2 + nlg(n) + 10 <= cn^3 f(n) <= n^3 + (n^3)*lg(n) + 10n^3 <= cn^3 f(n) <= N^3(11 + lg(n)) <= cn^3 so 11 + lg(n) = c But this can't be right because c must be constant. What am I doing wrong?

• How do you remove/clean-up code which is no longer used?

  - by clarke ching

  So, we have a project which had to be radically descoped in order to ship on time. It's got a lot of code left in it which is not actually used. I want to clean up the code, removing any dead-wood. I have the authority to do it and I can convince people that it's a commercially sensible thing to do. [I have a lot of automated unit tests, some automated acceptance tests and a team of testers who can manually regression test.] My problem: I'm a manager and I don't know technically how to go about it. Any help?

• Without using PECL or system() type functions, is there a way to look up DNS records using PHP?

  - by Navarr

  I'm working on creating a new type of email protocol, and in order to do that I had to set up an SRV DNS record for my domain. In promoting this protocol, I'll need to be able to discover if a given host uses my system (and if not fall back to an older protocol). So, is there a way to pull a DNS record (such as SRV) using PHP without using a PECL extension or running it through the linux command line (I already know I can ob_start() and system("host -t SRV hostname") but I'm looking for a better way, if it exists.)

• Creating Wiki Pages through code or CAML

  - by Joe Capka

  We are trying to create a site definition that includes a wiki page. Basically we are trying to figure out how to replicate the same process that happens when a user chooses to create a new page in a blank site, and the system says something along the lines of: "In order to create wiki pages on this site, there must be a default wiki page library and site assets library. Would you like to create those document libraries now?" When the user chooses yes, the system provisions those libraries as well as a few "howto" wiki pages. If anyone knows how to trigger that roll-out though code or CAML, we would appreciate the help.

• didSelectRowAtIndexPath being called after viewDidLoad of the called view

  - by Serguei Fedorov

  I am trying to pass variables over to the new view. I have the following code: appDelegate *dataCenter = (AppDelegate*)[[UIApplication sharedApplication] delegate]; dataCenter.myVariable = [array objectAtIndex:indexPath.row]; in the didSelectRowAtIndexPath of the calling view. However, the issue that I have is that this variable is empty in the vewDidLoad function of the next view, simply because it fired off BEFORE the didSelectRowAtIndexPath of the calling view. I am using storyboard to link the views together. Both are UITableView. If I hit back and then reselect the table element it is then set, granted that by the time I hit back and then selected again, the variable got set. Is there any way to for the order of execution? I really don't want to do UI view switching on the back end. Any help is greatly appreciated!

• Allow users to enter a variable length list of items in asp.net form

  - by EJB

  I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list. I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order). What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation?

• Google Play: how dev can give (already purchased) app to customer as a gift?

  - by Tertium

  Yes, SO, I know, it's not a "programmer's" question:) But customers sometimes help us (devs) with our code, so we (devs) shold be grateful. I think answer to my question will be useful for all fellow android devs. User has purchased my app. Refund period (15min) is over of course. Now I'd like to return money to him as a gift, because he helped me in testing a little. If I refund the entire order in Checkout-Orders will user keep my app 'purchased'? I mean will he be able to uninstall and install it again from GooglePlay-MyApps and will app be marked "purchased"? Will Google LVL accept him to run the app? I've done such refunds before, but then they called it "Android Market", and refund was 12h, and there were no LVL. Maybe somebody know another way to make a small gift using Google Play?

• LINQ Expression help with Func TEntity,TType

  - by Chris Conway

  I have a repository method that accepts an order by parameter in the form: public IEnumerable<TEntity> Get<TEntity>(Expression<Func<TEntity,string>> orderBy) Now that works fine when trying to sort by a property of type string, var entities = rep.Get(x => x.Name); but what if i want to sort by double or int or any other type. Doing something like var entities = rep.Get(x => x.Price); obviously throws a compile error saying I can't convert double to string. How can I make this more generic so I can sort by any property in my entity, or at least the properties where the type implements IComparable or something similar?
