• Parsing the Youtube API with DOM

  - by Kirk

  I'm using the Youtube API and I can retrieve the date information without a problem, but don't know how to retrieve the description information. My Code: <?php $v = "dQw4w9WgXcQ"; $url = "http://gdata.youtube.com/feeds/api/videos/". $v; $doc = new DOMDocument; $doc->load($url); $pub = $doc->getElementsByTagName("published")->item(0)->nodeValue; $desc = $doc->getElementsByTagName("media:description")->item(0)->nodeValue; echo "<b>Video Uploaded:</b> "; echo date( "F jS, Y", strtotime( $pub ) ); echo '<br>'; if (isset ($desc)) { echo "<b>Description:</b> "; echo $desc; echo '<br>'; } ?> Here's a link to the feed: http://gdata.youtube.com/feeds/api/videos/dQw4w9WgXcQ?prettyprint=true And the excerpt of code I don't know how to retrieve data from: <media:group> <media:description type='plain'>Music video by Rick Astley performing Never Gonna Give You Up. (C) 1987 PWL</media:description> </media:group> Thanks in advance.

• How do I correctly reference georss: point in my xsd?

  - by Chris Hinch

  I am putting together an XSD schema to describe an existing GeoRSS feed, but I am stumbling trying to use the external georss.xsd to validate an element of type georss:point. I've reduced the problem to the smallest components thusly: XML: <?xml version="1.0" encoding="utf-8"?> <this> <apoint>45.256 -71.92</apoint> </this> XSD: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:georss="http://www.georss.org/georss"> <xs:import namespace="http://www.georss.org/georss" schemaLocation="http://georss.org/xml/1.1/georss.xsd"/> <xs:element name="this"> <xs:complexType> <xs:sequence> <xs:element name="apoint" type="georss:point"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> If I make apoint type "xs: string" instead of "georss: point", the XML validates happily against the XSD, but as soon as I reference an imported type (georss: point), my XML validator (Notepad++ | XML Tools) "cannot parse the schema". What am I doing wrong?

• Using SMO to call Database.ExecuteNonQuery() concurrently?

  - by JimDaniel

  I have been banging my head against the wall trying to figure out how I can run update scripts concurrently against multiple databases in a single SQL Server instance using SMO. Our environments have an ever-increasing number of databases which need updating, and iterating through one at a time is becoming a problem (too slow). From what I understand SMO does not support concurrent operations, and my tests have bore that out. There seems to be shared memory at the Server object level, for things like DataReader context, keeps throwing exceptions such as "reader is already open." I apologize for not having the exact exceptions I am getting. I will try to get them and update this post. I am no expert on SMO and just feeling my way through to be honest. Not really sure I am approaching it the right way, but it's something that has to be done, or our productivity will slow to a crawl. So how would you guys do something like this? Am I using the wrong technology with SMO? All I am wanting to do is execute sql scripts against databases in a single sql server instance in parallel. Thanks for any help you can give, Daniel

• Which pdf elements could cause crashes?

  - by Felixyz

  This is a very general question but it's based on a specific problem. I've created a pdf reader app for the iPad and it works fine except for certain pdf pages which always crash the app. We now found out that the very same pages cause Safari to crash as well, so as I had started to suspect the problem is somewhere in Apple's pdf rendering code. From what I have been able to see, the crashing pages cause the rendering libraries to start allocating memory like mad until the app is killed. I have nothing else to help me pinpoint what triggers this process. It doesn't necessarily happen with the largest documents, or the ones with the most shapes. In fact, we haven't found any parameter that helps us predict which pages will crash and which not. Now we just discovered that running the pages through a consumer program that lets you merge docs gets rid of the problem, but I haven't been able to detect which attribute or element it is that is the key. Changing documents by hand is also not an option for us in the long run. We need to run an automated process on our server. I'm hoping someone with deeper knowledge about the pdf file format would be able to point me in a reasonable direction to look for document features that could cause this kind of behavior. All I've found so far is something about JBIG2 images, and I don't think we have any of those.

• Simple way of getting the Last.fm artist image for recently listened songs?

  - by animuson

  On the Last.fm website, your recently listened track include the 34x34 (or whatever size) image at the left of each song. However, in the RSS feed that they give you, no image URLs are provided for the songs. I was wondering if there was a good way of figuring out the ID for the image that needs to be used for that artist and displaying it based on the data that we're given. I know it is possible to load the artist page from their website and then grab the image values from JavaScript, but that seems overly complicated and would probably take quite some time to do. What we're given: <item> <title>Owl City – Rainbow Veins</title> <link>http://www.last.fm/music/Owl+City/_/Rainbow+Veins</link> <pubDate>Thu, 20 May 2010 18:15:29 +0000</pubDate> <guid>http://www.last.fm/user/animuson#1274379329</guid> <description>http://www.last.fm/music/Owl+City</description> </item> and the 34x34 image for this song would be here (ID# 37056785). Does anything like this exist? I've considered storing the ID number in a cache of some sort once it has been checked once, but what if the image changes?

• Java Regex for matching hexadecimal numbers in a file

  - by Ranman

  So I'm reading in a file (like java program < trace.dat) which looks something like this: 58 68 58 68 40 c 40 48 FA If I'm lucky but more often it has several whitespace characters before and after each line. These are hexadecimal addresses that I'm parsing and I basically need to make sure that I can get the line using a scanner, buffered reader... whatever and make sure I can then convert the hexadecimal to an integer. This is what I have so far: Scanner scanner = new Scanner(System.in); int address; String binary; Pattern pattern = Pattern.compile("^\\s*[0-9A-Fa-f]*\\s*$", Pattern.CASE_INSENSITIVE); while(scanner.hasNextLine()) { address = Integer.parseInt(scanner.next(pattern), 16); binary = Integer.toBinaryString(address); //Do lots of other stuff here } //DO MORE STUFF HERE... So I've traced all my errors to parsing input and stuff so I guess I'm just trying to figure out what regex or approach I need to get this working the way I want.

• Getting a UIImage from MySQL using PHP and jSON

  - by Daniel

  I'm developing a little news reader that retrieves the info from a website by doing a POST request to a URL. The response is a jSON object with the unread-news. E.g. the last news on the App has a timeStamp of "2013-03-01". When the user refreshes the table, it POSTS "domain.com/api/api.php?newer-than=2013-03-01". The api.php script goes to the MySQL database and fetches all the news posted after 2013-03-01 and prints them json_encoded. This is // do something to get the data in an array echo $array_of_fetched_data; for example the response would be [{"title": "new app is coming to the market", "text": "lorem ipsum dolor sit amet...", image: XXX}] the App then gets the response and parses it, obtaining an NSDictionary and adds it to a Core Data db. NSDictionary* obtainedNews = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error]; My question is: How can I add an image to the MySQL database, store it, pass it using jSON trough a POST HTTP Request and then interpret it as an UIImage. It's clear that to store an UIImage in CoreData, they must be transform into/from NSData. How can I pass the NSData back and forth to a MySQL db using php and jSON? How should I upload the image to the db? (Serialized, as a BLOB, etc)

I'm really stuck on this. Thanks!

• why can't i bind ipv6 socket to a linklocal address

• Sync two SqlExpress using NHibernate

  - by Christian

  Hello, I am creating a simple project management system which uses NHibernate for object storage. The underlying database is SQL express (at least currently for development). The client runs on either the desktop or laptop. I know I could use web-services and store the DB only on the desktop, but this would force the desktop to be available all the time. I am currently thinking about duplicating the DB, having two instances with "different data". To clarify, we are not talking about a productive app here, its a prototype. One way to achieve this very simple would be the following process: Client: Check if desktop DB is available (through web service) Client: If yes, use desktop storage, no problem here Client: If not, use own DB as storage Client: Poll desktop regulary, as soon as it comes on, sync Client: Switch to desktop storage ... Desktop: Do not attempt any DB operation before checking for required sync Desktop: If sync needed, do it... My question is now, how would you sync? Assume 4 or 5 types of objects, all have GUID as identifiers. Would you always manually "lazy load" all objects of a certain type and feed them to the DB. Would you always drop the whole desktop DB in case the client DB may be newer and out of sync? Again, I want to stress out, I am not assuming any conflicts or stale data, I basically just want to "copy the whole DB from the client". Would you use NHibernate for this? Or would you separate the copy process? When I think about it, my questions comes down to this: Is there any function from NHibernate: SyncDBs_SourceWins_(SourceDB, TargetDB) Thanks for help, Chris

• ASP.NET 2.0 + Firefox/Safari - UI Issues?

  - by Tejaswi Yerukalapudi

  I'm developing on a system that was originally developed five years ago. I don't have access to the complete source code of the system, but it is completely driven by XML and runs on ASP.NET 2.0. This was originally written for IE6, but since Microsoft has officially decided to dump it, we moved to IE7. Some javascript is added on the client side, but nothing that changes the UI has been done. (We had to integrate a credit card reader into the system) This code is accessed primarily on tablet PCs running windows, but I'd like to persuade my company to use the iPad. [The tablet somehow costs around 3k$. I think selling a 3000$ device to a client when you have the iPad for 500$ is ridiculous.] Now, my problem is if we open it in any other browser (Tested it on safari / firefox), the UI is completely messed up with elements completely out of place. Doesn't ASP.NET generate HTML that runs on any browser? My second question is if there are any credit card readers available in the market that integrate with the iPad. I don't really care about the software part as it's taken care by our company, I just need it to read the card details and post it to the server. Thanks, Teja.

• Robust DateTime parser library for .NET

  - by Frank Krueger

  Hello, I am writing an RSS and Mail reader app in C# (technically MonoTouch). I have run into the issue of parsing DateTimes. I see a lot of variance in how dates are presented in the wild and have begun writing a function like this: public static DateTime ParseTime(string timeStr) { var formats = new string[] { "ddd, d MMM yyyy H:mm:ss \"GMT+00:00\"", "d MMM yyyy H:mm:ss \"EST\"", "yyyy-MM-dd\"T\"HH:mm:ss\"Z\"", "ddd MMM d HH:mm:ss \"+0000\" yyyy", }; try { return DateTime.Parse(timeStr); } catch (Exception) { } foreach (var f in formats) { try { var t = DateTime.ParseExact(timeStr, f, CultureInfo.InvariantCulture); return t; } catch (Exception) { } } return DateTime.MinValue; } This, well, makes me sick. Three points. (1) It's silly of me to think that I can actually collect a format list that will cover everything out there. (2) It's wrong! Notice that I'm treating an EST date time as UTC (since .NET seems oblivious to time zones). (3) I don't like using exceptions for logic. I am looking for an existing library (source only please) that is known to handle a bunch of these formats. Also, I would like to keep using UTC DateTimes throughout my code so whatever library is suggested should be able to produce DateTimes. Is there anything out there like this?

• How To perform a SQL Query to DataTable Operation That Can Be Cancelled

  - by David W

  I tried to make the title as specific as possible. Basically what I have running inside a backgroundworker thread now is some code that looks like: SqlConnection conn = new SqlConnection(connstring); SqlCommand cmd = new SqlCommand(query, conn); conn.Open(); SqlDataAdapter sda = new SqlDataAdapter(cmd); sda.Fill(Results); conn.Close(); sda.Dispose(); Where query is a string representing a large, time consuming query, and conn is the connection object. My problem now is I need a stop button. I've come to realize killing the backgroundworker would be worthless because I still want to keep what results are left over after the query is canceled. Plus it wouldn't be able to check the canceled state until after the query. What I've come up with so far: I've been trying to conceptualize how to handle this efficiently without taking too big of a performance hit. My idea was to use a SqlDataReader to read the data from the query piece at a time so that I had a "loop" to check a flag I could set from the GUI via a button. The problem is as far as I know I can't use the Load() method of a datatable and still be able to cancel the sqlcommand. If I'm wrong please let me know because that would make cancelling slightly easier. In light of what I discovered I came to the realization I may only be able to cancel the sqlcommand mid-query if I did something like the below (pseudo-code): while(reader.Read()) { //check flag status //if it is set to 'kill' fire off the kill thread //otherwise populate the datatable with what was read } However, it would seem to me this would be highly ineffective and possibly costly. Is this the only way to kill a sqlcommand in progress that absolutely needs to be in a datatable? Any help would be appreciated!

• Multiple jQuery.noConflict() instances...

  - by user353816

  I am working with several jQuery scripts that include a MenuFader (http://css-tricks.com/examples/MenuFader/), twitter feed, and timestamp. Additionally I have a couple Mootools scripts that include the Barackslideshow (http://devthought.com/wp-content/moogets/BarackSlideshow/demo.html). And finally I have a scrolling ticker with tooltips taken from the twitter homepage. I originally had a conflict with the Jquery MenuFader and Mootools BarackSlideshow, but easily fixed this issue with the jQuery.noconflict(); and replaced all corresponding $ with jQuery. Unfortunately, after I added the scrolling ticker from Twitter, the Mootools BarackSlideshow and the Jquery MenuFader no longer work. I tried to implement jQuery.noconflict(); then $.noconflict(); then var j = jQuery.noconflict(); and replacing the $ as I did previously, but I cannot get the scripts to play nicely. Any help is greatly appreciated...I have been working on this all day. I am pretty new with javascript, but have managed to get through most problems with a little persistence. Please take a look at the script below: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js" type="text/javascript"></script> <script src="http://a2.twimg.com/a/1274914417/javascripts/fronts.js" type="text/javascript"></script> <script type="text/javascript"> //<![CDATA[ $( function () { setTimeout(function() { $(".twtr-widget").append($("<div></div>").attr("class", "twtr-fade")); }, 0); (function() { var tabIndex = $("[tabindex]:last").attr("tabIndex"); var setTabIndex = function() { $(this).attr("tabindex", ++tabIndex); } $(".footer-nav a").each(setTabIndex); $(".language-select a").each(setTabIndex); })(); $("#signup_submit").scribe({ event_name: "signup_submit_click", experiment: "ab_signup_button", bucket: "sign_up" }, "www_ab_tests"); $('#signin_menu').isSigninMenu(); new FrontPage().init(); }); //]]>

• Images from url to listview

  - by Andres

  I have a listview which I show video results from YouTube. Everything works fine but one thing I noticed is that the way it works seems to be a bit slow and it might be due to my code. Are there any suggestions on how I can make this better? Maybe loading the images directly from the url instead of using a webclient? I am adding the listview items in a loop from video feeds returned from a query using the YouTube API. The piece of code which I think is slowing it down is this: Feed<Video> videoFeed = request.Get<Video>(query); int i = 0; foreach (Video entry in videoFeed.Entries) { string[] info = printVideoEntry(entry).Split(','); WebClient wc = new WebClient(); wc.DownloadFile(@"http://img.youtube.com/vi/" + info[0].ToString() + "/hqdefault.jpg", info[0].ToString() + ".jpg"); string[] row1 = { "", info[0].ToString(), info[1].ToString() }; ListViewItem item = new ListViewItem(row1, i); YoutubeList.Items.Add(item); imageListSmall.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); imageListLarge.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); } public static string printVideoEntry(Video video) { return video.VideoId + "," + video.Title; } As you can see I use a Webclient which downloads the images so then I can use them as image in my listview. It works but what I'm concerned about is speed..any suggestions? maybe a different control all together?

• File streaming in PHP - How to replicate this C#.net code in PHP?

  I'm writing an interface to a web service where we need to upload configuration files. The documentation only provides a sample in C#.net which I am not familiar with. I'm trying to implement this in PHP. Can someone familiar with both languages point me in the right direction?

• Google App Engine - How to implement the activity stream in a social network

  - by spidee

  I want some ideas on the best practice to implement an activity stream for a social network im building in app engine (PYTHON) I first want to keep a log for all activities of each user - so that we have a history. i.e. someone became a friend, added a picture, changed their address etc. This way we have a users history available should we need it. Also mean we can remove friendship joins, change user data but have a historical log. I also want to stream a users activity to their friends. for this only the last X activities need to be kept - that is in the scenario that messages are sent to friends when an activity occurs. Its pretty straight forward designing a history log - ie: when, what, where. The complication comes as to how we notify friends of a user as to their activity. In our app friendships are not mutual - ie they are based on the twitter following model. Some accounts could have thousands of followers. What is the best approach to model this. using a many to many join table and doing a costly query - using a feed class that fired a copy of the activity to all the subscribers - maybe into mcache? As their maybe a need to fire thousands of messages i would imagine a cron job would need to be used. Any help ideas thoughts on this Thx

• Error 100 When Attempting to post from app to Facebook wall?

  - by IMAPC

  I'm playing around with the Facebook API, and have gotten far enough to get the access token into my app, but when I go to actually send a post to my Facebook wall I get the error message, {"error":{"message":"(#100) You can't post this because it has a blocked link.","type":"OAuthException","code":100}}1 I'm not attempting to send any kind of link, just "Hello, World!" so this seems pretty weird to me :\ Here's my code so far: $content = urlencode("Hello, World!"); $accesstoken = urlencode($row['fbid']); $result = getPageWithPOST("https://graph.facebook.com/me/feed", "access_token=" . $accesstoken . "&message=" . $content); echo $result; where getPageWithPOST is, function getPageWithPOST($url, $posts) { $c = curl_init(); curl_setopt($c, CURLOPT_URL, $url); curl_setopt($c, CURLOPT_POST, true); curl_setopt($c, CURLOPT_POSTFIELDS, $posts); $content = curl_exec ($c); curl_close ($c); return $content; } thanks!

• Modify SQL result set before returning from stored procedure

  - by m0sa

  I have a simple table in my SQL Server 2008 DB: Tasks_Table -id -task_complete -task_active -column_1 -.. -column_N The table stores instructions for uncompleted tasks that have to be executed by a service. I want to be able to scale my system in future. Until now only 1 service on 1 computer read from the table. I have a stored procedure, that selects all uncompleted and inactive tasks. As the service begins to process tasks it updates the task_active flag in all the returned rows. To enable scaleing of the system I want to enable deployment of the service on more machines. Because I want to prevent a task being returned to more than 1 service I have to update the stored procedure that returns uncompleted and inactive tasks. I figured that i have to lock the table (only 1 reader at a time - I know I have to use an apropriate ISOLATION LEVEL), and updates the task_active flag in each row of the result set before returning the result set. So my question is how to modify the SELECT result set iin the stored procedure before returning it?

  - by gadym

  hello all, i am new to the filestream option in sql server 2008, but i have already understand how to open this option and how to create a table that allow you to save files. let say my table contains: id,name, filecontent i tried to insert an html file (that has hebrew chars/text in it) to this table. i'm writing in asp.net (c#), using visual studio 2008. but when i tried to read back the content , hebrew char becomes '?'. the actions i took were: 1. i read the file like this: // open the stream reader System.IO.StreamReader aFile = new StreamReader(FileName, System.Text.UTF8Encoding.UTF8); // reads the file to the end stream = aFile.ReadToEnd(); // closes the file aFile.Close(); return stream; // returns the stream i inserted the 'stream' to the filecontent column as binary data. i tried to do a 'select' to this column and the data did return (after i coverted it back to string) but hebrew chars become '?' how do i solve this problem ? what I should pay attention to ? thanks, gadym

• increase number of photos from flickr using json

  - by Andrew Welch

  Hi this is my code: Is is possible to get more photos from flickr. What is the standard / default number? $(document).ready(function(){ $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?id=48719970@N07&lang=en-us&format=json&jsoncallback=?", function(data){ $.each(data.items, function(i, item){ var newurl = 'url(' + item.media.m + ')'; $("<div class='images'/>").css('background', newurl).css('backgroundPosition','top center').css('backgroundRepeat','no-repeat').appendTo("#images").wrap("<a target=\"_blank\ href='" + item.link + "'></a>"); }) $("#title").html(data.title); $("#description").html(data.description); $("#link").html("<a href='" + data.link + "' target=\"_blank\">Visit the Viget Inspiration Pool!</a>"); //Notice that the object here is "data" because that information sits outside of "items" in the JSON feed $('.jcycleimagecarousel').cycle({ fx: 'fade', speed: 300, timeout: 3000, next: '#next', prev: '#prev', pause: 1, random: 1 }); }); });
