  • How to fetch particular element from string after splitting it, using XSLT split() ?

    - by Vijay
    Hi All, I have one query regarding XSLT functions. I am using split function to fetch values from a string. I am using separator as "*". e.g. String : {"item1*item2*item3*item4"} split function I am using is as; <xsl:template name="SplitItemsCollection"> <xsl:param name="list" select="''"/> <xsl:param name="separator" select="'*'"/> <xsl:if test="not($list = '' or $separator = '')"> <xsl:variable name="head" select="substring-before(concat($list, $separator), $separator)"/> <xsl:variable name="tail" select="substring-after($list, $separator)"/> <xsl:value-of select="$head"/> <xsl:call-template name="split"> <xsl:with-param name="list" select="$tail"/> <xsl:with-param name="separator" select="$separator"/> </xsl:call-template> </xsl:if> </xsl:template> This function returns me all the items. Is there any way to fetch particular item from these separated items ? Say I want to fetch item3. Can we do it directly ? Thanks in advance.

  • In Varnish, how can I read the Set-Cookie response header?

    - by Adam Friedman
    I am trying to detect if my application has set a cookie that holds an "alert message" for the user on the next page, where the Javascript displays it if detected. In my vcl_fetch(), I need to detect if the specific cookie value "alert_message" appears anywhere in the Set-Cookie header (presumably in the VCL variable beresp.http.Set-Cookie). If detected, then I do not want to cache that next page (since Varnish strips the Set-Cookie header by default, which would obliterate the alert message before it makes it back to the browser). So here is my simple test: if(beresp.http.Set-Cookie ~ "alert_message") { set req.http.no_cache = 1; } Strangely, it fails to evaluate to true. So I throw the variable into the Server header to see what it looks like: set beresp.http.Server = " MyApp Varnish implementation - test reading set-cookie: "+beresp.http.Set-Cookie; But for some reason this only displays the FIRST Set-Cookie line in the response headers. Here are the relevant response headers: Server: MyApp Varnish implementation - test reading cookie: elstats_session=7d7279kjmsnkel31lre3s0vu24; expires=Wed, 10-Oct-2012 00:03:32 GMT; path=/; HttpOnly Set-Cookie:app_session=7d7279kjmsnkel31lre3s0vu24; expires=Wed, 10-Oct-2012 00:03:32 GMT; path=/; HttpOnly Set-Cookie:alert_message=Too+many+results.; expires=Tue, 09-Oct-2012 20:13:32 GMT; path=/; domain=.my.app.com Set-Cookie:alert_key=flash_error; expires=Tue, 09-Oct-2012 20:13:32 GMT; path=/; domain=.my.app.com Vary:Accept-Encoding How do I read and run string detection on ALL Set-Cookie header lines?

  • C: Global ,Static variables understanding

    - by pavun_cool
    Hi All, In following program . I have one doubt. I have declared one global variable . I am printing the address of the global variable in the function . It is giving me same address when I am not changing the value of global . If I did any changes in the global variables It is giving me different address why...........? Like that it is happening for static also. #include<stdio.h> int global=10 ; // Global variables void function(); main() { global=20; printf ( " %p \n" , global ) ; printf ( " Val: %d\n", global ) ; function(); new(); } void function() { global=30; printf ( " %p \n" , global ) ; printf ( " Val: %d\n", global ) ; } Thanks.

  • Can't unwrap Optional.None tableviewcell

    - by Mathew Padley
    I've a table view that has a custom table view cell in it. My problem is that when i try and assign a value to a variable in the custom table view cell I get the stated error. Now, I think its because the said variable is not initialised, but its got me completely stumped. This is the custom table cell: import Foundation import UIKit class LocationGeographyTableViewCell: UITableViewCell { //@IBOutlet var Map : MKMapView; @IBOutlet var AddressLine1 : UILabel; @IBOutlet var AddressLine2 : UILabel; @IBOutlet var County : UILabel; @IBOutlet var Postcode : UILabel; @IBOutlet var Telephone : UILabel; var location = VisitedLocation(); func Build(location:VisitedLocation) -> Void { self.location = location; AddressLine1.text = "test"; } } My cell for row at index path is: override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { var addressCell = tableView.dequeueReusableCellWithIdentifier("ContactDetail") as? LocationGeographyTableViewCell; if !addressCell { addressCell = LocationGeographyTableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: "ContactDetail"); } addressCell!.Build(Location); return addressCell; } As I say I'm completely baffled, the Build function calls the correct function in the tableviewcell. Any help will be gratefully appreciated. Ta

  • Model value not being set on return from View to Controller

    - by sagesky36
    I have a boolean model variable who's value is supposed to be set to TRUE in order to perform a process on return back into the Controller. It works absolutely fine on my local machine, but not on the remote web server. Can somebody PLEASE inform me what I am missing? Below is the "proof of the pudding": The boolean value in quesion is "ShouldGeneratePdf"; MODEL: namespace PDFConverterModel.ViewModels { public partial class ViewModelTemplate_Guarantors { public ViewModelTemplate_Guarantors() { Templates = new List<PDFTemplate>();

The values of the hidden variable when the page loads and when the last alert button finishes are as follows: My local machine: The remote machine: As you can see, the value on my machine is set to true when the process executes. However, on the remote machine, it is set to false where it then doesn't excute. Why isn't the value in the model being returned as TRUE on the remote machine?

  • Various way to stop a thread - which is the correct way

  • What's the best technique to protect my framework from visitors who are not logged in?

    - by Hermet
    First of all, I would like to say that I have used the search box looking for a similar question and was unsuccessful, maybe because of my poor english skills. I have a a 'homemade' framework. I have certain PHP files that must only be visible for the admin. The way I currently do this is check within every single page to see if a session has been opened. If not, the user gets redirected to a 404 page, to seem like the file which has been requested doesn't exist. I really don't know if this is guaranteed to work or if there's a better and more safe way because I'm currently working with kind of confidential data that should never become public. Could you give me some tips? Or leave a link where I could find some? Thank you very much, and again excuse me for kicking the dictionary. EDIT What I usually write in the top of each file is something like this <?php include("sesion.php"); $rs=comprueba(); //'check' if ($rs==1) { ?> And then, at the end <?php } ?> Is it such a butched job, isn't it? EDIT Let's say I have a customers list in a file named customers.php That file may be currently on http://www.mydomain.com/admin/customers.php and it must only be visible for the admin user. Once the admin user has been logged in, I create a session variable. That variable is what I check on the top of each page, and if it exists, the customers list is shown. If not, the user gets redirected to the 404 page. Thank you for your patience. I really appreciate.

  • reshaping a data frame into long format in R

    - by user1773115
    I'm struggling with a reshape in R. I have 2 types of error (err and rel_err) that have been calculated for 3 different models. This gives me a total of 6 error variables (i.e. err_1, err_2, err_3, rel_err_1, rel_err_2, and rel_err_3). For each of these types of error I have 3 different types of predivtive validity tests (ie random holdouts, backcast, forecast). I would like to make my data set long so I keep the 4 types of test long while also making the two error measurements long. So in the end I will have one variable called err and one called rel_err as well as an id variable for what model the error corresponds to (1,2,or 3) Here is my data right now: iter err_1 rel_err_1 err_2 rel_err_2 err_3 rel_err_3 test_type 1 -0.09385732 -0.2235443 -0.1216982 -0.2898543 -0.1058366 -0.2520759 random 1 0.16141630 0.8575728 0.1418732 0.7537442 0.1584816 0.8419816 back 1 0.16376930 0.8700738 0.1431505 0.7605302 0.1596502 0.8481901 front 1 0.14345986 0.6765194 0.1213689 0.5723444 0.1374676 0.6482615 random 1 0.15890059 0.7435382 0.1589823 0.7439204 0.1608709 0.7527580 back 1 0.14412360 0.6743928 0.1442039 0.6747684 0.1463520 0.6848202 front and here is what I would like it to look like: iter model err rel_err test_type 1 1 -0.09385732 (#'s) random 1 2 -0.1216982 (#'s) random 1 3 -0.1216982 (#'s) random and on... I've tried playing around with the syntax but can't quite figure out what to put for the time.varying argument Thanks very much for any help you can offer.

  • Does Interlocked guarantee visibility to other threads in C# or do I still have to use volatile?

    - by Lirik
    I've been reading the answer to a similar question, but I'm still a little confused... Abel had a great answer, but this is the part that I'm unsure about: ...declaring a variable volatile makes it volatile for every single access. It is impossible to force this behavior any other way, hence volatile cannot be replaced with Interlocked. This is needed in scenarios where other libraries, interfaces or hardware can access your variable and update it anytime, or need the most recent version. Does Interlocked guarantee visibility of the atomic operation to all threads, or do I still have to use the volatile keyword on the value in order to guarantee visibility of the change? Here is my example: public class CountDownLatch { private volatile int m_remain; // <--- do I need the volatile keyword there since I'm using Interlocked? private EventWaitHandle m_event; public CountDownLatch (int count) { Reset(count); } public void Reset(int count) { if (count < 0) throw new ArgumentOutOfRangeException(); m_remain = count; m_event = new ManualResetEvent(false); if (m_remain == 0) { m_event.Set(); } } public void Signal() { // The last thread to signal also sets the event. if (Interlocked.Decrement(ref m_remain) == 0) m_event.Set(); } public void Wait() { m_event.WaitOne(); } }

  • N3WB Question: passing objects in java?

    - by Adam Outler
    Hello, I am new at java. I am doing the following: Read from file, then put data into a variable. checkToken = lineToken.nextToken(); processlinetoken() } But then when I try to process it... public static void readFile(String fromFile) throws IOException { BufferedReader reader = new BufferedReader(new FileReader(fromFile)); String line = null; while ((line=reader.readLine()) != null ) { if (line.length() >= 2) { StringTokenizer lineToken = new StringTokenizer (line); checkToken = lineToken.nextToken(); ...... But here's where I come into a problem. public static void processlinetoken() checkToken=lineToken.nextToken(); } it fails out. Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method nextToken() is undefined for the type String at testread.getEngineLoad(testread.java:243) at testread.readFile(testread.java:149) at testread.main(testread.java:119) so how do I get this to work? It seems to pass the variable, but nothing after the . works.

  • JSTL <c:out> where the element name contains a space character...

    - by Shane
    I have an array of values being made available, but unfortunately some of the variable names include a space. I cannot work out how to simply output these in the page. I know I'm not explaining this well (I'm the JSP designer, not the Java coder) so hopefully this example will illustrate what I'm trying to do: <c:out value="${x}"/> outputs to the page (artificially wrapped) as: {width=96.0, orderedheight=160.0, instructions=TEST ONLY. This is a test., productId=10132, publication type=ns, name=John} I can output the name by using <c:out value="${x.name}"/> no problems. The issue is when I try to get the "publication type"... because it has a space, I can't seem to get <c:out> to display it. I have tried: <!-- error parsing custom action attribute: --> <c:out value="${x.publication type}"/> <!-- error occurred while evaluating custom action attribute: --> <c:out value="${x.publication+type}"/> <!-- error occurred while parsing custom action attribute: --> <c:out value="${x.'publication type'}"/> <!-- error occurred while parsing custom action attribute: --> <c:out value="${x.publication%20type}"/> I know the real solution is to get the variable names formatted correctly (ie: without spaces) but I can't get the code updated for quite a while. Can this be done? Any help greatly appreciated.

  • How can I get HTML to link to a browser (or system) specified URL?

    - by MrHatken
    Hi All, I'd like to be able to create a "HTML link" that the user can click on and be taken to an URL (location) specified either in the browser (preferences?) or system environment. Is this possible? Any suggestions on how to do it please? For example, it may look something like this (or alternatively it could be a clickable image or even a submit button): "Click here to go to your preferred news site." When the user clicks on "here" the browser would go to a location specified not in the HTML but somehow in the browser (preferences?) or some system environment variable (OS specific etc.) Of course, the user would have to set up this preference or environment variable (or have some local application or better Web page that could set it - when approved by the user). This is sort of like most OS these days allow you to set "preferred app" for image processing or playing media. I would like to set preferred Web sites for certain tasks. Thanks for any suggestions. Hopefully with Javascript and modern browsers and perhaps HTML 5 something like this is possible. Cheers, Ashley.

  • Php JSON Response Array

    - by Nick Kl
    I have this php code. As you can see i query a mysql database through a function showallevents. I return a the $result to the $event variable. I try to return all rows of the data that i take with the msql_fetch_assoc. I don't get response even when i encode the $response variable. It returns null to all fields. Can anyone help me on what i am doing wrong. I had a valid code but it was returning only 1 row of data so i tried to make an associative array but seems i am failing. if ($tag == 'showallevents') { // Request type is show all events // show all events $event = $db->showallevents(); if ($event != false) { $data = array(); while($row = mysql_fetch_assoc($event)) { $data[] = array( $response["success"] = 1, $response["uid"] = $event["uid"], $response["event"]["date"] = $event["date"], $response["event"]["hours"] = $event["hours"], $response["event"]["store_name"] = $event["store_name"], $response["event"]["event_information"] = $event["event_information"], $response["event"]["event_type"] = $event["event_type"], $response["event"]["Phone"] = $event["Phone"], $response["event"]["address"] = $event["address"], $response["event"]["created_at"] = $event["created_at"], $response["event"]["updated_at"] = $event["updated_at"]); } echo json_encode($data); } else { // event not found // echo json with error = 1 $response["error"] = 1; $response["error_msg"] = "Events not found"; echo json_encode($response); } } else { echo "Access Denied"; } } ?>

  • How do I put my return data from an asmx into JSON?

    - by jphenow
    I want to return an array of javascript objects from my asp.net asmx file. ie. variable = [ { *value1*: 'value1', *value2*: 'value2', ..., }, { . . } ]; I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable. Thanks in advance for assistance. EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.

  • Refactor link to show/hide a table row

    - by abatishchev
    I have a table with row which cab be hidden by user. It's implemented this way: Markup: <table> <tr> <td> <table style="margin-left: auto; text-align: right;"> <tr> <td class="stats-hide"> <a href="#" onclick="hideStats();">Hide</a> </td> <td class="stats-show" style="display: none;"> <a href="#" onclick="showStats();">Show</a> </td> </tr> </table> </td> </tr> <tr class="stats-hide"> <td> <!-- data --> </td> </tr> </table> And jQuery code: <script type="text/javascript" language="javascript"> function hideStats() { hideControls(true, $('.stats-hide')); hideControls(false, $('.stats-show')); } function showStats() { hideControls(false, $('.stats-hide')); hideControls(true, $('.stats-show')); } function hideControls(value, arr) { $(arr).each(function () { if (value) { $(this).hide(); } else { $(this).show(); } }); } </script> How to implement the same behavior with one, single link and one, probably, CSS class? My idea - store somewhere a boolean variable and toggle controls visibility relatively to this variable. Are there more?

  • Writing an auto-memoizer in Scheme. Help with macro and a wrapper.

    - by kunjaan
    I am facing a couple of problems while writing an auto-memoizer in Scheme. I have a working memoizer function, which creats a hash table and checks if the value is already computed. If it has been computed before then it returns the value else it calls the function. (define (memoizer fun) (let ((a-table (make-hash))) (?(n) (define false-if-fail (?() #f)) (let ((return-val (hash-ref a-table n false-if-fail))) (if return-val return-val (begin (hash-set! a-table n (fun n)) (hash-ref a-table n))))))) Now I want to create a memoize-wrapper function like this: (define (memoize-wrapper function) (set! function (memoizer function))) And hopefully create a macro called def-memo which defines the function with the memoize-wrapper. eg. the macro could expand to (memoizer (define function-name arguments body ...) or something like that. So that I should be able to do : (def-memo (factorial n) (cond ((= n 1) 1) (else (* n (factorial (- n 1)))))) which should create a memoized version of the factorial instead of the normal slow one. My problem is that the The memoize-wrapper is not working properly, it doesnt call the memoized function but the original function. I have no idea how to write a define inside of the macro. How do I make sure that I can get variable lenght arguments and variable length body? How do I then define the function and wrap it around with the memoizer? Thanks a lot.

  • MySQL: How to pull information from multiple tables based on information in other tables?

    - by Greg
    Ok, I have 5 tables which I need to pull information from based on one variable. gameinfo id | name | platforminfoid gamerinfo id | name | contact | tag platforminfo id | name | abbreviation rosterinfo id | name | gameinfoid rosters id | gamerinfoid | rosterinfoid The 1 variable would be gamerinfo.id, which would then pull all relevant data from gamerinfo, which would pull all relevant data from rosters, which would pull all relevant data from rosterinfo, which would pull all relevant data from gameinfo, which would then pull all relevant data from platforminfo. Basically it breaks down like this: gamerinfo contains the gamers basic information. rosterinfo contains basic information about the rosters (ie name and the game the roster is aimed towards) rosters contains the actual link from the gamer to the different rosters (gamers can be on multiple rosters) gameinfo contains basic information about the games (ie name and platform) platform info contains information about the different platforms the games are played on (it is possible for a game to be played on multiple platforms) I am pretty new to SQL queries involving JOINs and UNIONs and such, usually I would just break it up into multiple queries but I thought there has to be a better way, so after looking around the net, I couldn't find (or maybe I just couldn't understand what I was looking at) what I was looking for. If anyone can point me in the right direction I would be most grateful.

  • In Django, how to define a "location path" in order to display it to the users?

    - by naw
    I want to put a "location path" in my pages showing where the user is. Supposing that the user is watching one product, it could be Index > Products > ProductName where each word is also a link to other pages. I was thinking on passing to the template a variable with the path like [(_('Index'), 'index_url_name'), (_('Products'), 'products_list_url_name'), (_('ProductName'), 'product_url_name')] But then I wonder where and how would you define the hierarchy without repeating myself (DRY)? As far I know I have seen two options To define the hierarchy in the urlconf. It could be a good place since the URL hierarchy should be similar to the "location path", but I will end repeating fragments of the paths. To write a context processor that guesses the location path from the url and includes the variable in the context. But this would imply to maintain a independient hierarchy wich will need to be kept in sync with the urls everytime I modify them. Also, I'm not sure about how to handle the urls that require parameters. Do you have any tip or advice about this? Is there any canonical way to do this?

  • How do I refer to a windows form control by name (C# / VB)

    - by Alex
    Suppose I have a label control on a windows form called "UserName". How can I refer to that label programmatically using the label name? For example I can do: For each ctrl as Control in TabPage.Controls If ctrl.Name = "UserName" Then ' Do something End If Next This seems quite inefficient. I would like to do something like: TabPage.Controls("UserName").Text = "Something" I did some googling but couldn't find a satisfactory answer. Most suggested looping, some said .NET 2005 doesn't support direct refenece using string name, and FindControl method was asp.net only... EDIT Thanks for the response so far. Here is a bit more detail. I have a windows form with three tabpages, all of which a very similar in design and function i.e. same drop down menus, labels, react in simlar way to events etc. Rather than write code for each event per tabpage I have built a class that controls the events etc. per tabpage. For example, on each tabpage there is a Label called "RecordCounter" that simply shows the number of rows in the datagridview when it is populated by selection of a variable in a drop down menu. So what I want to be able to do is, upon selection of a variable in the drop down menu, the datagridview populates itself with data, and then I simply want to display the number of rows in a label ("RecordCounter"). This is exactly the same process on each tabpage so what I am doing is passing the tabpage to the class and then I want to be able to refer to the "RecordCounter" and then update it. In my class I set the ActivePage property to be the TabPage that the user has selected and then want to be able to do something like: ActivePage.RecordCounter.Text = GetNumberOfRows()

  • CDN for Images in ASP.NET

    - by Chris
    I am in the process of moving all of the images in my web application over to a CDN but I want to easily be able to switch the CDN on or off without having to hard code the path to the images. My first thought was to add an HttpHandler for image extensions that depending whether a variable in the web.config (something like ) will serve the image from the server or from the CDN. But after giving this a little though I think I've essentially ruled this out as it will cause ASP.NET to handle the request for every single image, thus adding overhead, and it might actually completely mitigate the benefits of using a CDN. An alternative approach is, since all of my pages inherit from a base page class, I could create a function in the base class that determines what path to serve the files from based off the web.config variable. I would then do something like this in the markup: <img src='<%= GetImagePath()/image.png' /> I think this is probably what I'll have to end up doing, but it seems a little clunky to me. I also envision problems with the old .NET error of not being able to modify the control collection because of the "<%=" though the "<%#" solution will probably work. Any thoughts or ideas on how to implement this?

  • PHP Header redirection problem within page called by cURL

    - by Das123
    I have a site that uses cURL to access some pages, stores the returned results in variables, and then uses these variables within its own page. The script works well except where the target cURL page has a header('Location: ...') command inside it. It seems to just ignore this header command. The cURL command is as follows... //Load result page into variable so portions can be allocated to correct variables $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); # URL to post to curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 ); # return into a variable curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields); $loaded_result = curl_exec( $ch ); # run! curl_close($ch); I've tried changing the CURLOPT_HEADER to 1 but it doesn't do anything. So how can I allow script redirection within the target urls using cURL to grab the results? By the way, the pages work fine if accessed other than via cURL but iFrames are not an option in this instance.

  • Haskell: Dealing With Types And Exceptions

    - by Douglas Brunner
    I'd like to know the "Haskell way" to catch and handle exceptions. As shown below, I understand the basic syntax, but I'm not sure how to deal with the type system in this situation. The below code attempts to return the value of the requested environment variable. Obviously if that variable isn't there I want to catch the exception and return Nothing. getEnvVar x = do { var <- getEnv x; Just var; } `catch` \ex -> do { Nothing } Here is the error: Couldn't match expected type `IO a' against inferred type `Maybe String' In the expression: Just var In the first argument of `catch', namely `do { var <- getEnv x; Just var }' In the expression: do { var <- getEnv x; Just var } `catch` \ ex -> do { Nothing } I could return string values: getRequestURI x = do { requestURI <- getEnv x; return requestURI; } `catch` \ex -> do { return "" } however, this doesn't feel like the Haskell way. What is the Haskell way?

  • How to stop input in Perl?

    - by user1472747
    First time poster and part time perl noobie. I'm making a reflex game. Here's the output - __________________________________________________________________________ Reflex game initiated. Press ENTER to begin the game, and then press ENTER after the asterisks are printed to measure your reflexes!. ************************* Your result: 0.285606 seconds. logout [Process completed] __________________________________________________________________________ There's one small problem though - There's 0-10 seconds (based on a random variable) after you press enter to start the game and before the stars are printed. During that time, if the player presses ENTER, it's logged as their reflex time. So I need a way to stop my code from reading their ENTER button before the stars are printed. The code - #!/usr/bin/perl use Time::HiRes qw(sleep); use Time::HiRes qw(gettimeofday); #random delay variable $random_number = rand(); print "Reflex game initiated. Press ENTER to begin the game, and then press ENTER after the asterisks are printed to measure your reflexes!.\n"; #begin button $begin = <>; #waits x milliseconds sleep(10*$random_number); #pre-game $start = [ Time::HiRes::gettimeofday() ]; print "\n****************************\n"; #user presses enter $stop = <>; #post game $elapsed = Time::HiRes::tv_interval($start); #delay time print print "Your result: ".$elapsed." seconds.\n";
