  • LINQ to XML contents of child records.

    - by Fossaw
    I have this LINQ to XML enquiry... var Records = from Item in XDoc.Root.Elements("Item") where (string)Item.Element("ItemNumber") == item.ID.ToString select Item; ... where ItemNumber is a reference number used in the XML, (originally written by this program but manually edited by "others"), and item.ID is the database version of the same thing. The query executes, and I can test for the number of entries in the result fine... if (Records.Count() < 1) ... you get the idea. I have established that there is only one record. Each Item has several child fields. I want to test the values of the child fields are reasonable before passing them on to the database update sub-system. The XML is produced by the program, but edited by users, so I need to really check what is coming back. So I tried... if (DB_English.ToString() != Records.Elements("English").ToString()) ... DB_English is from the database, but the XML in Records, does not contain the contents of that field, it contains... System.Xml.Linq.Extensions+<GetElements>d__29`1[System.Xml.Linq.XElement] ... so, how do I get the value of this element in the XML file? I need to check the field in the XML has not been altered, (the manual editors of this data file are not potentially 100% reliable).

  • Merging datasets with 2 different time variables in SAS

    - by John
    Hye Guys, for those regularly browsing this site sorry for already another question (however I did solve my last question myself!) I have another problem with merging datasets, it seems that accounting for time in datasets is a real pain in the ass. I succesfully managed to merge on months in my previous datasets, however it seems I have a final dataset which only has quarter as a time count variable. So where all my normal databases have month 1- xxx as an indicator of time, this database had quarter as an indicator of time. I still want to add the variables of this last database, let's call it TVOL, into my WORK database. Quick summary QUARTER: Quarter 0 = JAN1996-MAR1996 Month: Month 0 = JAN1996 Example: TVOL TVOL _ Ticker ____ Quarter 1500 _ AA ________ -1 52546 _ BB ________ 15 Example: WORK BETA _ Ticker ____ Month 1.52 _ AA ________ 2 1.54__ BB _______ 3 Example: Merged: BETA ______ TVOL __ Ticker ____ Month 1.52 _______ 500 ___ AA _______ 2 I now want to merge this 2 tables using following relationship if the month is in quarter 1, the data of quarter 0 has to be used, so if i have an observation i nWORK with date 2FEB1996 the TVOL of quarter -1 has to be put behind this observation. Something like IF month = quarter i use data quarter i-1. Also, as TVOL is measured quarterly and I have to put in monthly I have to take the average, so (TVOL/3) should be added as a variable. Thanks!

  • Strings exported from a module have changed line breaks

    - by Jesse Millikan
    In a DrScheme project, I'm using a MrEd editor-canvas% with text% and inserting a string from a literal in a Scheme file. This results in an extra blank line in the editor for each line of text I'm trying to insert. I've tracked this down to the apparent fact that string literals from outside modules are getting extra line breaks. Here's a full example. The editor is irrelevant at this point, but it displays the result. ; test-literals.ss (module test-literals scheme (provide (all-defined-out)) (define exported-string "From another module with some more line breaks. ")) ; editor-test.ss (module editor-test scheme (require mred "test-literals.ss") (define w (instantiate frame% ("Editor Test" #f) )) (define c (instantiate editor-canvas% (w) (line-count 12) (min-width 400))) (define editor (instantiate text% ())) (send c set-editor editor) (send w show #t) (send editor erase) (send editor insert "Some text with some line breaks. ") (send editor insert exported-string)) And the result in the editor is Some text with some line breaks. From another module with some more line breaks. I've traced in and figured out that it's changing Unix line breaks to Windows line breaks when strings are imported from another module, but these display as double line breaks. Why is this happening and is there a way to stop it other than changing every imported string?

  • Create xml file to be used in wordpress post import

    - by adedoy
    Alright here is the thing, I have this site that was once wordpress but have been converted into 70+ static pages, the admin is deleted and the whole site is static(which means every page is in index.html), I want to create a script that makes an xml so that I will just have to import it in the new wordpress install. So far, I am able to create an XML but it only imports one post. The data source is the URL of a page and I use jquery $get to filter only to gather the post of a given archive. //html <input type="text" class="full_path"> <input type="button" value="Get Data" class="getdata"> //script $('.getdata').click(function(){ $.get($('.full_path').val(), function(data) { post = $(data).find('div [style*="width:530px;"]'); $('.result').html(post.html()); }); });//get Data Through AJAX I send the cleaned data into a php below that creates the XML: $file = 'newpost.xml'; $post_data = $_REQUEST['post_data']; // Open the file to get existing content $current = file_get_contents($file); // Append a new post to the file $catStr = ''; if(isset($post_data['categories']) && count($post_data['categories']) > 0){ foreach($post_data['categories'] as $category) { $catStr .= '<category domain="category" nicename="'.$category.'"><![CDATA['.$category.']]></category>'; } } $tagStr = ''; if(isset($post_data['tags']) && count($post_data['tags']) > 0){ foreach($post_data['tags'] as $tag) { $tagStr = '<category domain="post_tag" nicename="'.$tag.'"><![CDATA['.$tag.']]></category>'; } } $post_name = str_replace(' ','-',$post_data["title"]); $post_name = str_replace(array('"','/',':','.',',','[',']','“','”'),'',strtolower($post_name)); $post_date = '2011-4-0'.rand(1, 29).''.rand(1, 12).':'.rand(1, 59).':'.rand(1, 59); $pubTime = rand(1, 12).':'.rand(1, 59).':'.rand(1, 59).' +0000'; $post = ' <item> <title>'.$post_data["title"].'</title> <link>'.$post_data["link"].'</link> <pubDate>'.$post_data["date"].'

  • Why isn't this simple PHP/MySQL code working?

    - by Sammy
    I am very new to php/mysql and this is causing me to loose hairs, I am trying to build a multi level site navigation. In this part of my script I am readying the sub and parent categories coming from a form for insertion into the database: // get child categories $catFields = $_POST['categories']; if (is_array($catFields)) { $categories = $categories; for ($i=0; $i<count($catFields); $i++) { $categories = $categories . $catFields[$i]"; } } // get parent category $select = mysql_query ("SELECT parent FROM categories WHERE id = $categories"); while ($return = mysql_fetch_assoc($select)) { $parentId = $return['parent']; } The first part of my script works fine, it grabs all the categories that the user has chosen to assign a post by checking the checkboxes in a form and readies it for insertion into the database. But the second part does not work and I can't understand why. I am trying to match a category with a parent that is stored in it's own table, but it returns nothing even though the categories all have parents. Can anyone tell me why this is? p.s. The $categories variable contains the sub category id.

  • Existing LINQ extension method similar to Parallel.For?

    - by Joel Martinez
    The linq extension methods for ienumerable are very handy ... but not that useful if all you want to do is apply some computation to each item in the enumeration without returning anything. So I was wondering if perhaps I was just missing the right method, or if it truly doesn't exist as I'd rather use a built-in version if it's available ... but I haven't found one :-) I could have sworn there was a .ForEach method somewhere, but I have yet to find it. In the meantime, I did write my own version in case it's useful for anyone else: using System.Collections; using System.Collections.Generic; public delegate void Function<T>(T item); public delegate void Function(object item); public static class EnumerableExtensions { public static void For(this IEnumerable enumerable, Function func) { foreach (object item in enumerable) { func(item); } } public static void For<T>(this IEnumerable<T> enumerable, Function<T> func) { foreach (T item in enumerable) { func(item); } } } usage is: myEnumerable.For<MyClass>(delegate(MyClass item) { item.Count++; });

  • Sql query - selecting top 5 rows and further selecting rows only if User is present

    - by Gublooo
    Hello, I kind of stuck on how to implement this query - this is pretty similar to the query I posted earlier but I'm not able to crack it. I have a shopping table where everytime a user buys anything, a record is inserted. Some of the fields are * shopping_id (primary key) * store_id * user_id Now what I need is to pull only the list of those stores where he's among the top 5 visitors: When I break it down - this is what I want to accomplish: * Find all stores where this UserA has visited * For each of these stores - see who the top 5 visitors are. * Select the store only if UserA is among the top 5 visitors. The corresponding queries would be: select store_id from shopping where user_id = xxx select user_id,count(*) as 'visits' from shopping where store_id in (select store_id from shopping where user_id = xxx) group by user_id order by visits desc limit 5 Now I need to check in this resultset if UserA is present and select that store only if he's present. For example if he has visited a store 5 times - but if there are 5 or more people who have visited that store more than 5 times - then that store should not be selected. So I'm kind of lost here. Thanks for your help

  • specifying multiple URLs with cURL/PHP using square brackets

    - by Raj Gundu
    I have a large array of URLS similar to this: $nodes = array( 'http://www.example.com/product.php?page=1&sortOn=sellprice', 'http://www.example.com/product.php?page=2&sortOn=sellprice', 'http://www.example.com/product.php?page=3&sortOn=sellprice' ); The cURL manual states here (http://curl.haxx.se/docs/manpage.html) that i can use square brackets '[]' to specify multiple urls. Used in the above example this would be similar to this: 'http://www.example.com/product.php?page=[1-3]&sortOn=sellprice' So far i have been unable to reference this correctly. This is the complete code segment I'm currently trying to utilize this with: $nodes = array( 'http://www.example.com/product.php?page=1&sortOn=sellprice', 'http://www.example.com/product.php?page=2&sortOn=sellprice', 'http://www.example.com/product.php?page=3&sortOn=sellprice' ); $node_count = count($nodes); $curl_arr = array(); $master = curl_multi_init(); for($i = 0; $i < $node_count; $i++) { $url =$nodes[$i]; $curl_arr[$i] = curl_init($url); curl_setopt($curl_arr[$i], CURLOPT_RETURNTRANSFER, true); curl_multi_add_handle($master, $curl_arr[$i]); } do { curl_multi_exec($master,$running); } while($running > 0); echo "results: "; for($i = 0; $i < $node_count; $i++) { $results = curl_multi_getcontent ( $curl_arr[$i] ); echo( $i .

  • Using MongoDB's map/reduce to "group by" two fields

    - by ibz
    I need something slightly more complex than the examples in the MongoDB docs and I can't seem to be able to wrap my head around it. Say I have a collection of objects of the form {date: "2010-10-10", type: "EVENT_TYPE_1", user_id: 123, ...} Now I want to get something similar to a SQL GROUP BY query, grouping over both date and type. That is, I want the number of events of each type in each day. Also, I'd like to make it unique by user_id, ie. if a user has more events in the same day, count it only once. I'm trying to do this with map/reduce. I do db.logs.mapReduce(function() { emit(this.type, 1); }, function(k, vals) { var total = 0; for (var i = 0; i < vals.length; i++) total += vals[i]; return total; }}) which nicely groups by type, but now, how can I group by date at the same time? Seems the key in emit() can't be an array (I thought about doing emit([this.date, this.type], 1)). Also, how can I ensure the per-user uniqueness? I'm just starting with MongoDB and I'm still having trouble grasping the basic concepts. Also, there is not much documentation available out there. Any help from more experienced users is appreciated. Thanks!

  • Double Click and Resize on an Ipad

  • Making a query result equal to zero when a condition is null

    - by John
    Hello, I believe the query below should work. However, when I run it, the results are blank. I think this is happening since for now, the table "comment" is empty. So there is no instance where s.submissionid = c.submissionid. I would like to have the query below to work even if there if no s.submissionid that equals a c.submissionid. In this case, I would like countComments to equal zero. How can I do this? Thanks in advance, John $sqlStr = "SELECT s.loginid, s.submissionid s.title, s.url, s.displayurl, l.username, count(c.comment) AS countComments FROM submission AS s, login AS l, comment AS c, WHERE s.loginid = l.loginid AND s.submissionid = c.submissionid GROUP BY s.loginid, s.submissionid s.title, s.url, s.displayurl, l.username ORDER BY s.datesubmitted DESC LIMIT 10"; $result = mysql_query($sqlStr); $arr = array(); echo "<table class=\"samplesrec\">"; while ($row = mysql_fetch_array($result)) { echo '<tr>'; echo '<td class="sitename1"><a href="http://www.'.$row["url"].'">'.$row["title"].'</a></td>'; echo '</tr>'; echo '<tr>'; echo '<td class="sitename2"><a href="http://www...com/sandbox/members/index.php?profile='.$row["username"].'">'.$row["username"].'</a><a href="http://www...com/sandbox/comments/index.php?submission='.$row["title"].'">'.$row["countComments"].'</a></td>'; echo '</tr>'; } echo "</table>";

  • Using Rails, problem testing has_many relationship

    - by east
    The summary is that I've code that works when manually testing, but isn't doing what I would think it should when trying to build an automated test. Here are the details: I've two models: Payment and PaymentTranscation. class Payment ... has_many :transactions, :class_name => 'PaymentTransaction' class PaymentTranscation ... belongs_to payment The PaymentTransaction is only created in a Payment model method, like so: def pay_up ... transactions.create!(params...) ... end I've manually tested this code, inspected the database, and everything works well. The failing automated test looks like this: def test_pay_up purchase = Payment.new(...) assert purchase.save assert_equal purchase.state, :initialized.to_s assert purchase.pay_up # this should create a new PaymentTransaction... assert_equal purchase.state, :succeeded.to_s assert_equal purchase.transactions.count, 1 # FAILS HERE; transactions is an empty array end If I step through the code, it's clear that the PaymentTransaction is getting created correctly (though I can't see it in the database because everything is in a testing transaction). What I can't figure out is why transactions is returning an empty array in the test when I know a valid PaymentTransaction is getting created. Anybody have some suggestions? Thanks in advance, east

  • Disposing underlying object from finalizer in an immutable object

    - by Juan Luis Soldi
    I'm trying to wrap around Awesomium and make it look to the rest of my code as close as possible to NET's WebBrowser since this is for an existing application that already uses the WebBrowser. In this library, there is a class called JSObject which represents a javascript object. You can get one of this, for instance, by calling the ExecuteJavascriptWithResult method of the WebView class. If you'd call it like myWebView.ExecuteJavascriptWithResult("document", string.Empty).ToObject(), then you'd get a JSObject that represents the document. I'm writing an immutable class (it's only field is a readonly JSObject object) called JSObjectWrap that wraps around JSObject which I want to use as base class for other classes that would emulate .NET classes such as HtmlElement and HtmlDocument. Now, these classes don't implement Dispose, but JSObject does. What I first thought was to call the underlying JSObject's Dispose method in my JSObjectWrap's finalizer (instead of having JSObjectWrap implement Dispose) so that the rest of my code can stay the way it is (instead of having to add using's everywhere and make sure every JSObjectWrap is being properly disposed). But I just realized if more than two JSObjectWrap's have the same underlying JSObject and one of them gets finalized this will mess up the other JSObjectWrap. So now I'm thinking maybe I should keep a static Dictionary of JSObjects and keep count of how many of each of them are being referenced by a JSObjectWrap but this sounds messy and I think could cause major performance issues. Since this sounds to me like a common pattern I wonder if anyone else has a better idea.

  • Windows-1251 file inside UTF-8 site?

    - by Spoonk
    Hello everyone Masters Of Web Delevopment :) I have a piece of PHP script that fetches last 10 played songs from my winamp. This script is inside file (lets call it "lastplayed.php") which is included in my site with php include function inside a "div". My site is on UTF-8 encoding. The problem is that some songs titles are in Windows-1251 encoding. And in my site they displays like "??????"... Is there any known way to tell to this div with included "lastplayed.php" in it, to be with windows-1251 encoding? Or any other suggestions? P.S: The file with fetching script a.k.a. "lastplayed.php", is converted to UTF-8. But if it is ANCII it's the same result. I try to put and meta tag with windows-1251 between head tag but nothing happens again. P.P.S: Script that fetches the Winamp's data (lastplayed.php): <?php /****** * You may use and/or modify this script as long as you: * 1. Keep my name & webpage mentioned * 2.

  • Delphi: Problems with TList of Frames

    - by Dan Kelly
    I'm having a problem with an interface that consists of a number of frames (normally 25) within a TScrollBox. There are 2 problems, and I am hoping that one is a consequence of the other... Background: When the application starts up, I create 25 frames, each containing approx. 20 controls, which are then populated with the default information. The user can then click on a control to limit the search to a subset of information at which point I free and recreate my frames (as the search may return < 25 records) The problem: If I quit the application after the initial search then it takes approx. 5 seconds to return to Delphi. After the 2nd search (and dispose / recreate of frames) it takes approx. 20 seconds) Whilst I could rewrite the application to only create the frames once, I would like to understand what is going on. Here is my create routine: procedure TMF.CreateFrame(i: Integer; var FrameBottom: Integer); var NewFrame: TSF; begin NewFrame := TSF.Create(Self); NewFrame.Name := 'SF' + IntToStr(i); if i = 0 then NewSF.Top := 8 else NewSF.Top := FrameBottom + 8; FrameBottom := NewFrame.Top + NewFrame.Height; NewFrame.Parent := ScrollBox1; FrameList.Add(NewFrame); end; And here is my delete routine: procedure TMF.ClearFrames; var i: Integer; SF: TSF; begin for i := 0 to MF.FrameList.Count -1 do begin SF := FrameList[i]; SF.Free; end; FrameList.Clear; end; What am I missing?

  • Reading Certificates on iOS Problem

    - by David Schiefer
    I am trying to read certificates from various URLs in iOS. My code however is not working well - the array that should return the information I need always returns null. What am I missing? - (void)findCertificate:(NSString *)url { NSInputStream*input = [[NSInputStream inputStreamWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://store.writeitstudios.com"]]] retain]; [input setDelegate:self]; [input scheduleInRunLoop:[NSRunLoop mainRunLoop] forMode:NSDefaultRunLoopMode]; [input open]; NSLog(@"Status: %i",[input streamStatus]); } - (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode { NSLog(@"handle Event: %i",eventCode); if (eventCode == NSStreamStatusOpen) { NSArray *certificates = (NSArray*)CFReadStreamCopyProperty((CFReadStreamRef)aStream, kCFStreamPropertySSLPeerCertificates); NSLog(@"Certs: %@",CFReadStreamCopyProperty((CFReadStreamRef)aStream, kCFStreamPropertySSLPeerCertificates)); if ([certificates count] > 0) { SecCertificateRef certificate = (SecCertificateRef)[certificates objectAtIndex:0]; NSString *description = (NSString*)SecCertificateCopySubjectSummary(certificate); NSData *data = (NSData *)SecCertificateCopyData(certificate); NSLog(@"Description: %@",description); } } } And yes, I am aware that I am leaking memory. This is just a snippet.

  • Why do my raytraced spheres have dark lines when lit with multiple light sources?

    - by Curyous
    I have a simple raytracer that only works back up to the first intersection. The scene looks OK with two different light sources, but when both lights are in the scene, there are dark shadows where the lit area from one ends, even if in the middle of a lit area from the other light source (particularly noticeable on the green ball). The transition from the 'area lit by both light sources' to the 'area lit by just one light source' seems to be slightly darker than the 'area lit by just one light source'. The code where I'm adding the lighting effects is: // trace lights for ( int l=0; l<primitives.count; l++) { Primitive* p = [primitives objectAtIndex:l]; if (p.light) { Sphere * lightSource = (Sphere *)p; // calculate diffuse shading Vector3 *light = [[Vector3 alloc] init]; light.x = lightSource.centre.x - intersectionPoint.x; light.y = lightSource.centre.y - intersectionPoint.y; light.z = lightSource.centre.z - intersectionPoint.z; [light normalize]; Vector3 * normal = [[primitiveThatWasHit getNormalAt:intersectionPoint] retain]; if (primitiveThatWasHit.material.diffuse > 0) { float illumination = DOT(normal, light); if (illumination > 0) { float diff = illumination * primitiveThatWasHit.material.diffuse; // add diffuse component to ray color colour.red += diff * primitiveThatWasHit.material.colour.red * lightSource.material.colour.red; colour.blue += diff * primitiveThatWasHit.material.colour.blue * lightSource.material.colour.blue; colour.green += diff * primitiveThatWasHit.material.colour.green * lightSource.material.colour.green; } } [normal release]; [light release]; } } How can I make it look right?

  • Why does File.Exists return false?

    - by Jonas Stawski
    I'm querying all images on the Android device as such: string[] columns = { MediaStore.Images.Media.InterfaceConsts.Data, MediaStore.Images.Media.InterfaceConsts.Id }; string orderBy = MediaStore.Images.Media.InterfaceConsts.Id; var imagecursor = ManagedQuery(MediaStore.Images.Media.ExternalContentUri, columns, null, null, orderBy); for (int i = 0; i < this.Count; i++) { imagecursor.MoveToPosition(i); Paths[i]= imagecursor.GetString(dataColumnIndex); Console.WriteLine(Paths[i]); Console.WriteLine(System.IO.File.Exists(Paths[i])); } The problem is that the output shows that some files don't exist. Here's a sample output: /storage/sdcard0/Download/On-Yom-Kippur-Jews-choose-different-shoes-VSETQJ6-x-large.jpg False /storage/sdcard0/Download/397277_10151250943161341_876027377_n.jpg False /storage/sdcard0/Download/Roxy_Cottontail_&_Melo-X_Present..._Some_Bunny_Love's_You.jpg False /storage/sdcard0/Download/album-The-Rolling-Stones-Some-Girls.jpg True /storage/sdcard0/Download/some-people-ust-dont-appreciate-fashion[1].jpg True /storage/sdcard0/Download/express.gif True ... /storage/sdcard0/Download/some-joys-are-expressed-better-in-silence.JPG False How is this possible?

  • I'm looking for a way to evaluate reading rate in several languages

    - by i30817
    I have a software that is page oriented instead of scrollbar oriented so i can easily count the words, but i'd like a way to filter outliers and some default value for the text language (that is known). The goal is from the remaining text to calculate the remaining time. I'm not sure what is the best unit to use. WPM (words per minute) from here seems very fuzzy and human oriented. Besides i don't know how many "words" remain in the text. http://www.sfsu.edu/~testing/CalReadRate.htm So i came up with this: The user is reading the text. The total text size in characters is known. His position in the text is known. So the remaining characters to read is also known. If a language has a median word length of say 5 chars, then if i had a WPM speed for the user, i could calculate the remaining time. 3 things are needed for this: 1) A table of the median word length of the language. 2) A table of the median WPM of a median user per language. 3) Update the WPM to fit the user as data becomes available, filtering outliers. However i can't find these tables. And i'm not sure how precise it is assuming median word length.

  • XSL-FO: Static content AND Flow content in Region-Body: Possible?

    - by Peterdk
    I have the following problem: I need to use XSLFO to generate a 2-column multipage document. Problem is: I need to have a vertical line between the 2 columns. Since XSLFO does not seem to specify a option for creating such a divider, I need to manually put it there. I was thinking of using a static rotated blockcontainer with a leader in it. However, it looks like it's not possible to use static-content on the same region as where the flow content comes. <fo:layout-master-set> <fo:simple-page-master page-width="170mm" page-height="222mm" master-name="page" > <fo:region-body region-name="xsl-region-body" margin-top="2mm" margin-bottom="2mm" margin-left="10mm" margin-right="10mm" column-count="2" column-gap="5mm" /> </fo:simple-page-master> </fo:layout-master-set> <fo:page-sequence master-reference="page"> <fo:static-content flow-name="xsl-region-body" ><!-- This gives a error --> <fo:block>test</fo:block> </fo:static-content> <fo:flow flow-name="xsl-region-body"> <xsl:apply-templates/> </fo:flow> </fo:page-sequence> Results in (XEP): [error] Duplicate identifier: flow-name="xsl-region-body". Property 'flow-name' should be unique within 'fo:page-sequence'. Are there any methods to place static content on the main region when also flow content is placed there? Or: Is there a way to define the divider that divides a 2-column layout?
