    - by Mike
    What i have is four comboboxes and two files. If the column matches the combobox i need to write it out to a file but it has to appened with the second combobox. So for example Combobox1: Apple | Orange Combobox2: Pineapple | Plum I have selected Apple Plum I need to search threw a text file and find whatever columns is Apple or Plum: Orange|Pear|Peach|Turnip|Monkey|Apple|Grape|Plum and then i need to write out just the columns Apple|Plum to a new text file.

  • User Control not loading based on location

    - by mwright
    I have an ASP.net MVC solution that uses nested master pages to load content. On the first Master page I load a header, then have the Content Placeholder, and then load a footer. This master page is referenced by another master page which adds some additional information based on the user being logged in or not. When I load a page that references these master pages, the header loads, but the footer does not. If I move the footer up above the Content Place Holder it loads into the page. Any ideas why this might be the case? The code for the master page that contains the footer is as follows: <%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title> <asp:ContentPlaceHolder ID="TitleContent" runat="server" /> </title> </head> <body> <div class="header"> <% Html.RenderPartial("Header"); %> </div> <div> <asp:ContentPlaceHolder ID="MainContent" runat="server"> </asp:ContentPlaceHolder> </div> <div class="footer"> <% Html.RenderPartial("Footer"); %> </div> </body> </html>

  • Getting the height of text to know fill height as in TCPDF

    - by sami
    I'm trying to go through the code of TCPDF to understand how it calculates the height of the text to be rendered, but it's too much for me to handle without asking. What I want to know: in the PDF from example 5 http://www.tcpdf.org/examples/example_005.pdf it gives the cell a yellow background. I'm guessing that at the basic level, it first draws a box with this fill color, then adds the text, so what method is it calling to get the height of the text to know the height of the box to fill? Anyone knows how to trace this, because doing it by hand and looking through the code isn't working at all for me.

  • Automatic music rating based on listening habits

    - by marco92w
    I've created a Winamp-like music player in Delphi. Not so complex, of course. Just a simple one. But now I would like to add a more complex feature: Songs in the library should be automatically rated based on the user's listening habits. This means: The application should "understand" if the user likes a song or not. And not only whether he/she likes it but also how much. My approach so far (data which could be used): Simply measure how often a song was played per time. Start counting time when the song was added to the library so that recent songs don't have any disadvantage. Measure how long a song was played on average (minutes). Starting a song but directly change to another one should have a bad influence on the ranking since the user didn't seem to like the song. ... Could you please help me with this problem? I would just like to have some ideas. I don't need the implementation in Delphi.

  • SQL statement to split a table based on a join

    - by williamjones
    I have a primary table for Articles that is linked by a join table Info to a table Tags that has only a small number of entries. I want to split the Articles table, by either deleting rows or creating a new table with only the entries I want, based on the absence of a link to a certain tag. There are a few million articles. How can I do this? Not all of the articles have any tag at all, and some have many tags. Example: table Articles primary_key id table Info foreign_key article_id foreign_key tag_id table Tags primary_key id It was easy for me to segregate the articles that do have the match right off the bat, so I thought maybe I could do that and then use a NOT IN statement but that is so slow running it's unclear if it's ever going to finish. I did that with these commands: INSERT INTO matched_articles SELECT * FROM articles a LEFT JOIN info i ON a.id = i.article_id WHERE i.tag_id = 5; INSERT INTO unmatched_articles SELECT * FROM articles a WHERE a.id NOT IN (SELECT m.id FROM matched_articles m); If it makes a difference, I'm on Postgres.

  • How can I put text from a multi-line text box into one string?

    - by Kevin van Zanten
    Dear reader, I'm faced with a bit of an issue. The scenario is that I have a multi-line text box and I want to put all that text into one single string, without any new lines in it. This is what I have at the moment: string[] values = tbxValueList.Text.Split('\n'); foreach (string value in values) { if (value != "" && value != " " && value != null && value != "|") { valueList += value; } } The problem is that no matter what I try and what I do, there is always a new line (at least I think?) in my string, so instead of getting: "valuevaluevalue" I get: "value value value". I've even tried to replace with string.Replace and regex.Replace, but alas to no avail. Please advise. Yours sincerely, Kevin van Zanten

  • Help a Beginner with a PHP based Login System

    - by Brian Lang
    I'm a bit embarrassed to say, but I've run into issue with creating a PHP based login system. I'm using a site template to handle the looks of the the login process, so I will spare you the code. Here is my thought process on how to handle the login: Create a simple login.php file. On there will be a form whose action is set to itself. It will check to see if the submit has been clicked, and if so validate to make sure the user entered a valid password / username. If they do, set a session variable save some login info (username, NOT password), and redirect them to a restricted area. If the login info isn't valid, save an error message in a session variable, display error message giving further instruction, and wait for the user to resubmit. Here is a chunk of what I have - hopefully one of you experts can see where I've gone wrong, and give me some insight: if(isset($_POST['submit'])) { if(!empty($_POST['username']) AND !empty(!$_POST['password'])) { header("Location: http://www.google.com"); } else { $err = 'All the fields must be filled in!'; } } if($err) { $_SESSION['msg']['login-err'] = $err; } ? Now the above is just an example - the intent of the above code is to process user input, with the script validating simply that the user has given input for username and password. If they have, I would like them, in this case, to be redirected to google.com (for the sake of this example). If not, save an error message. Given my current code, the error message will display perfectly, however if the user submits and has something entered for the username and password, the page simply doesn't redirect. I'm sure this is a silly question, but I am a beginner, and well, to be honest, a bit buzzed right now. Thanks so much!

  • overlay text on some else's window - HUD

    - by taglius
    I am interested in writing an app that overlays a small heads up display (HUD) over another application, in VB.NET. Does anyone have an example of this? I will need to enumerate all open windows to find the window that I want, and then overlay some text in a specific position on the window. If the user moves that window, my text will need to follow. (I will probably be painting the text in a loop over and over). Edit: nobody answered my original query - I added C# to the keywords to see if any of gurus in that language might have an answer. thanks.

  • jQuery UI Rang Slider show divs based on selected range

    - by andi_sf
    I have set up a range slider that should show/hide divs based on their range values - meaning if the range of the one specifies in the div falls into the selected range in the slider it should show - the others hide. Somehow it does not work correctly - if anybody could help that would be greatly appreciated. My code so far: $("#slider").slider({ range: true, min: 150, max: 280, step: 5, values: [150, 280], slide: function(event, ui) { $("#amount").val('Min. Value' + ui.values[0] + ' - Max. Value' + ui.values[1]); }, change: function(event, ui) { $('#col-2 div').each(function(){ var valueS = parseInt($(this).attr("class")); var valueX = parseInt($(this).attr("title")); if (valueS < ui.values[0] && valueX <= ui.values[1] || valueS ui.values[0] && valueX = ui.values[1] ) { $(this).stop().animate({opacity: 0.25}, 500) } else { $(this).stop().animate({opacity: 1.0}, 500) $("#amount").val('Min. Value' + ui.values[0] + ' - Max. Value' + ui.values[1]); } }); } }); $("#amount").val('Min. Value' + $("#slider").slider("values", 0) + ' - Max. Value' + $("#slider").slider("values", 1)); }); I have also posted a sample at: http://www.webdesigneroakland.com/slider/444range_slider.html

  • selectively show wordpress posts based on category

    - by Andy
    Hi, Currently I'm using the following code as part of sidebar code for Wordpress (the code works fine): <ul class="linklist"> <?php $recentPosts = new WP_Query(); $recentPosts->query('showposts=12'); while ($recentPosts->have_posts()) : $recentPosts->the_post(); ?> <li><a href="<?php the_permalink() ?>" rel="bookmark" title="Link to <?php the_title(); ?>"> <?php the_title(); ?></a> </li> <?php endwhile;?> </ul> It shows the last 12 posts. But what I'm looking for is the following; first check what category the current post (the post that is showing based on the permalink) belongs to, and then only list the latest posts that belong to that same category. What should be edited? Thanks!

  • Looking for a web based, embeddable file manager

    - by Kristi H.
    I'm looking for a web based, embeddable file manager. I haven't found anything suitable through Google or the Stack Overflow archives. Does anyone know of a file manager that meets the following criteria? The file manager must… …be embeddable (e.g. Flash or a Java applet) …run from my server (no storing uploads in a remote location) …be licensed for business use (fees are okay) …let me disable uploads. Users shouldn't be able to upload files, only download them …allow me to tag files and/or place them in folders …let me disable authentication or handle it from the backend. My app already has a login system and I don't want to make users log in twice …allow users to select and download multiple files …have an attractive interface The file manager should… …have an external config file …display thumbnail previews for files …be skinnable …be actively developed or at least actively maintained Thanks for your help. I need a sophisticated file manager and I'd like to avoid writing it from scratch.

  • Using recursion to to trim a binary tree based on a given min and max value

    - by Justin
    As the title says, I have to trim a binary tree based on a given min and max value. Each node stores a value, and a left/right node. I may define private helper methods to solve this problem, but otherwise I may not call any other methods of the class nor create any data structures such as arrays, lists, etc. An example would look like this: overallRoot _____[50]____________________ / \ __________[38] _______________[90] / \ / _[14] [42] [54]_____ / \ \ [8] [20] [72] \ / \ [26] [61] [83] trim(52, 65); should return: overallRoot [54] \ [61] My attempted solution has three methods: public void trim(int min, int max) { rootFinder(overallRoot, min, max); } First recursive method finds the new root perfectly. private void rootFinder(IntTreeNode node, int min, int max) { if (node == null) return; if (overallRoot.data < min) { node = overallRoot = node.right; rootFinder(node, min, max); } else if (overallRoot.data > max) { node = overallRoot = node.left; rootFinder(node, min, max); } else cutter(overallRoot, min, max); } This second method should eliminate any further nodes not within the min/max, but it doesn't work as I would hope. private void cutter(IntTreeNode node, int min, int max) { if (node == null) return; if (node.data <= min) { node.left = null; } if (node.data >= max) { node.right = null; } if (node.data < min) { node = node.right; } if (node.data > max) { node = node.left; } cutter(node.left, min, max); cutter(node.right, min, max); } This returns: overallRoot [54]_____ \ [72] / [61] Any help is appreciated. Feel free to ask for further explanation as needed.

  • Posting an image and textual based data to a wcf service

    - by James Hay
    I have a requirement to write a web service that allows me to post an image to a server along with some additional information about that image. I'm completely new to developing web services (normally client side dev) so I'm a little stumped as to what I need to look into and try. How do you post binary data and plain text into a servic? What RequestFormat should I use? It looks like my options are xml or json. Can I use either of these? Bit of a waffly question but I just need some direction rather than a solution as I can't seem to find much online.

  • Choose a XML node in SQL Server based on max value of a child element

    - by Jay
    I am trying to select from SQL Server 2005 XML datatype some values based on the max data that is located in a child node. I have multiple rows with XML similar to the following stored in a field in SQL Server: <user> <name>Joe</name> <token> <id>ABC123</id> <endDate>2013-06-16 18:48:50.111</endDate> </token> <token> <id>XYX456</id> <endDate>2014-01-01 18:48:50.111</endDate> </token> </user> I want to perform a select from this XML column where it determines the max date within the token element and would return the datarows similar to the result below for each record: Joe XYZ456 2014-01-01 18:48:50.111 I have tried to find a max function for xpath that would all me to select the correct token element but I couldn't find one that would work. I also tried to use the SQL MAX function but I wasn't able to get it working with that method either. If I only have a single token it of course works fine but when I have more than one I get a NULL, most likely because the query doesn't know which date to pull. I was hoping there would be a way to specify a where clause [max(endDate)] on the token element but haven't found a way to do that. Here is an example of the one that works when I only have a single token: SELECT XMLCOL.query('user/name').value('.','NVARCHAR(20)') as name XMLCOL.query('user/token/id').value('.','NVARCHAR(20)') as id XMLCOL.query('user/token/endDate').value(,'xs:datetime(.)','DATETIME') as endDate FROM MYTABLE

  • Linux time sample based profiler.

    - by Caspin
    short version: Is there a good time based sampling profiler for Linux? long version: I generally use OProfile to optimize my applications. I recently found a shortcoming that has me wondering. The problem was a tight loop spawning c++filt to demangle a c++ name. I only stumbled upon the code by accident while chasing down another bottleneck. The OProfile didn't show anything unusual about the code so I almost ignored it but my code sense told me to optimize the call and see what happened. I changed the popen of c++filt to abi::__cxa_demangle. The runtime went from more than a minute to a little over a second. About a x60 speed up. Is there a way I could have configured OProfile to flag the popen call? As the profile data sits now OProfile thinks the bottle neck was the heap and std::string calls (which BTW once optimized dropped the runtime to less than a second, more than x2 speed up). Here is my OProfile configuration: $ sudo opcontrol --status Daemon not running Event 0: CPU_CLK_UNHALTED:90000:0:1:1 Separate options: library vmlinux file: none Image filter: /path/to/excutable Call-graph depth: 7 Buffer size: 65536 Is there another profiler for Linux that could have found the bottleneck? I suspect the issue is that OProfile only logs its samples to the currently running process. I'd like it to always log its samples to the process I'm profiling. So if the process is currently switched out (blocking on IO or a popen call) OProfile would just place its sample at the blocked call. If I can't fix this, OProfile will only be useful when the executable is pushing near 100% CPU. It can't help with executables that that have inefficient blocking calls.

  • File based caching under PHP

    - by azatoth
    I've been using http://code.google.com/p/phpbrowscap/ for a project, and it usually works nice. But a few times it's cache, which is plain php-files (see http://code.google.com/p/phpbrowscap/source/browse/trunk/browscap/Browscap.php#372 et. al.), has been "zeroed", i.e. the whole cache file has become large blob of NULLs. Instead of trying to find out why the files become NULL, I though perhaps it might be better to change the caching strategy to something more resilient. So I do wonder if you has any good ideas what would be a good solution; I've been looking at http://www.jongales.com/blog/2009/02/18/simple-file-based-php-cache-class/ and http://www.phpclasses.org/package/313-PHP-Cache-arbitrary-data-in-files-.html and I also though of just saving an serialized array to the file instead of pure php as it's been doing now; But I'm uncertain what approach I should target here. I'm grateful for any insight into this area of technology, as I know it's complex from a performance point of view.

  • How to combine multiple uiBinder-based widgets?

  • Group / User based security. Table / SQL question

    - by Brett
    Hi, I'm setting up a group / user based security system. I have 4 tables as follows: user groups group_user_mappings acl where acl is the mapping between an item_id and either a group or a user. The way I've done the acl table, I have 3 columns of note (actually 4th one as an auto-id, but that is irrelevant) col 1 item_id (item to access) col 3 user_id (user that is allowed to access) col 3 group_id (group that is allowed to access) So for example item1, peter, , item2, , group1 item3, jane, , so either the acl will give access to a user or a group. Any one line in the ACL table with either have an item - user mapping, or an item group. If I want to have a query that returns all objects a user has access to, I think I need to have a SQL query with a UNION, because I need 2 separate queries that join like.. item - acl - group - user AND item - acl - user This I guess will work OK. Is this how its normally done? Am I doing this the right way? Seems a little messy. I was thinking I could get around it by creating a single user group for each person, so I only ever deal with groups in my SQL, but this seems a little messy as well..
