  • Save all xml nodes to db without looping through it

    - by AndreMiranda
    I have this xml: <Path> <Record> <ID>6534808</ID> <Distance>1.05553036073736</Distance> </Record> <Record> <ID>6542471</ID> <Distance>1.05553036073736</Distance> </Record> ... and about more 500 nodes </Path> And I'm using the code below to get all "Record" nodes: XmlNodeList paths = xDoc.SelectNodes("//Record"); And, after that, I save each record to database. But, the problem is that I'm using a foreach to loop through this nodes and the count of this nodes may be more than 500, sometimes it gets up to 1000 "Records" node. And this gets too long... Is there a way to save all of these nodes without looping through it? Thanks!!

  • What's the best way to develop a debugging window for an ajax ASP.Net MVC application

    - by KallDrexx
    While developing my ASP.NET MVC, I have started to see the need for a debugging console window to assist in figuring out what is going right and wrong in my code. I read the last few chapters of the Pro Asp.net MVC book, and the author details how to use http modules to show page load/creation times and linq to sql query logs, both of which I definitely want to be able to see. However, since I am loading a lot of small sections of my page individually with ajax I don't want the debug information right there in the middle of my screen. So the idea I came up with was to have a separate browser window (open-able by a link or some javascript) with a console log, that can contain logged entries both from javascript and from the asp.net mvc run. The former should be relatively easy, but I'm having trouble coming up with a way to log the asp.net information in ajax requests. The direction I have been thinking of going is to create an httpmodule (like the Pro MVC book does), and have that module contain some that append the javascript's log to console calls with the messages. The issue I see with this is finding a way to get the log messages from the controller's action methods to the httpmodule's methods. The only way I see to do this is with a singleton, but I'm not sure if singletons are bad practice for a stateless web application. Furthermore, it seems like if I return json with my ajax calls (instead of pure html) then that won't work at all anyways and unless there is a way to add data to an existing json structure inside the httpmodule. How does everyone else handle this type of debugging in heavily ajax applications? For reference, the javascript library I am using is jquery.

  • reading from app.config file

    - by Sathish
    I am trying to read StartingMonthColumn and CategoryHeadingColumn from the below app.config file using the code ConfigurationSettings.AppSettings["StartingMonthColumn"] but it is returning null, also ConfigurationSettings.AppSettings.Count returns zero Please help me to read this in my windows application <configuration> <configSections> <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="CTARepository.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> </sectionGroup> </configSections> <userSettings> <CTARepository.Properties.Settings> <setting name="Setting" serializeAs="String"> <value /> </setting> </CTARepository.Properties.Settings> </userSettings> <appSettings> <add key="StartingMonthColumn" value="7"/> <add key="CategoryHeadingColumn" value="1"/> </appSettings>

  • Does anyone knows any Train-table-api service?

    - by DaNieL
    Hi guys, im wondering if there is any online service who provide API about the train timetables (arrivals, departure, etch..), at least for the european stations. I know www.bahn.de, who provide the accurated timetables for many european countries, but i didin't find any similar to a api service. My goal (well, just a future-project) is to develope an application like gmaps, but instead of giving the car-trip i would like to give the train-trip.. you know, the user set the departure day, time and station, then the first arrival, maybe then add another one, and so on. So, there is something like, that can be queryed by php/python/javascript? Edit: if can help, im wondering to build a service to plan an inter-rail trip! (and any help will be really appreciate) Im stuck. Google's public-service api rely on the information that every local company makes avaiable, much branches are missing (for example, is almost impossible to use it to build an itinerary that touches two or more regions of Europe. As i said before, the only service that i know doing it good is the bahn.de, they really have all the data.. but no api. I tryed to parse theyre result page (in order to use them as API), but seem like the markup is been build exactly to avoid that.. maybe they have business plans behind that or whatever, but i dont think they will ever release some API.. so, my project is going on without this function (p.s: my project is about non-profit cultural organizations, we wont make war to anyone ;P) @El Goorf: if you find a way, and consider the idea of sharing it, count on my hand if need help!

  • iPhone UITableView stutters with custom cells. How can I get it to scroll smoothly?

    - by Charles S.
    I'm using a UITableView to display custom cells created with Interface Builder. The table scrolling isn't very smooth (it "stutters") which leaves me to believe cells aren't being reused. Is there something wrong with this code? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"TwitterCell"; TwitterCell *cell = (TwitterCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ //new cell NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"TwitterCell" owner:nil options:nil]; for(id currentObject in topLevelObjects) { if([currentObject isKindOfClass:[TwitterCell class]]) { cell = (TwitterCell *)currentObject; break; } } } if([self.tweets count] > 0) { cell.lblUser.text = [[self.tweets objectAtIndex:[indexPath row]] username]; cell.lblTime.text = [[self.tweets objectAtIndex:[indexPath row]] time]; [cell.txtText setText:[[self.tweets objectAtIndex:[indexPath row]] text]]; [[cell imgImage] setImage:[[self.tweets objectAtIndex:[indexPath row]] image]]; } else { cell.txtText.text = @"Loading..."; } cell.selectionStyle = UITableViewCellSelectionStyleNone; return cell; }

  • Resolve sibling folder in JavaScript Function

    - by Jamen Chu
    Hi, I am trying to pass into an JavaScript function two paths for an XML and XSLT. It would appear that in the sample HTML below that the use of "../xsl/filename" does not work for me in the xslt() function. If I specify the path as being "./filename" though this does work. Does anyone know how I can work around this or find some way that I can specify a sibling folder without an absolute path reference? I would prefer not to have to change my file paths as my development environment is set up with the xslt's, sample data and source code structured in a particular way. Thanks in advance Jamen <html> <head> <title></title> <script type="text/javascript" src="../lib/jsunit/app/jsUnitCore.js"></script> <script type="text/javascript" src="../lib/jquery-1.2.3.js"></script> <script type="text/javascript" src="../lib/jquery.xslt.js"></script> </head> <body> <div id="bla"></div> <script type="text/javascript"> $('#bla').xslt("../sampledata/response1.xml", "../xslt/resultFormatter.xsl"); //function testjQuery() { // $('#bla').xslt("../sampledata/response1.xml", "../xslt/resultFormatter.xsl"); //} </script> </body> </html>

  • Iterating through String word at a time in Python

    - by AlgoMan
    I have a string buffer of a huge text file. I have to search a given words/phrases in the string buffer. Whats the efficient way to do it ? I tried using re module matches. But As i have a huge text corpus that i have to search through. This is taking large amount of time. Given a Dictionary of words and Phrases. I iterate through the each file, read that into string , search all the words and phrases in the dictionary and increment the count in the dictionary if the keys are found. One small optimization that we thought was to sort the dictionary of phrases/words with the max number of words to lowest. And then compare each word start position from the string buffer and compare the list of words. If one phrase is found, we don search for the other phrases (as it matched the longest phrase ,which is what we want) Can some one suggest how to go about word by word in the string buffer. (Iterate string buffer word by word) ? Also, Is there any other optimization that can be done on this ?

  • PHP site keeps opening to blank page, no errors.

    - by gene
    First, the premises: PHP loaded on IIS6 on Win2003 STD R2 SP2, PHP_5213 using FastCGI, MySQL_5145. Customer sent me the site files, which I unzipped to C:\InetPub\wwwroot\<site root>, then I created a new site in IIS, pointed to <site root>, added test.php to the site files for testing and it works, but visiting index.php produces a blank page with no errors. The readme.txt file present makes reference to application.php and explains root folder var and sets it to a non-existent file. I don't know PHP syntax, but I tried several logical changes with zero results. At this point I'm not even sure if that is the problem anymore. With PHP, MySQL & site debugging have put in over 20 hours. Still confused, I have resorted to heavy drug use and purchased a small firearm, loaded with a single round (even this seemed to take an inordinate amount of time). I've given up all hope. Someone please help save a new server and/or old administrator.

  • X++ Coming Out Of QueryRun In Fetch Method

    - by will
    I can't seem to find the resolution for this. I have modified the Fetch method in a report, so that if the queryRun is changed, and the new ID is fetched, then the while loop starts over and a new page appears and 2 elements are executed. This part works fine, the next part does not, in each ID there are several Records which I am using Element.Execute(); and element.Send(); to process. What happens is, the first ID is selected, the element (body) of the reports is executed and the element is sent as expected, however the while loop does not go onto the next ID? Here is the code; public boolean fetch() { APMPriorityId oldVanId, newVanId; LogisticsControlTable lLogisticsControlTable; int64 cnt, counter; ; queryRun = new QueryRun(this); if (!queryRun.prompt() || !element.prompt()) { return false; } while (queryRun.next()) { if (queryRun.changed(tableNum(LogisticsControlTable))) { lLogisticsControlTable = queryRun.get(tableNum(LogisticsControlTable)); if (lLogisticsControlTable) { info(lLogisticsControlTable.APMPriorityId); cnt = 0; oldVanId = newVanId; newVanId = lLogisticsControlTable.APMPriorityId; if(newVanId) { element.newPage(); element.execute(1); element.execute(2); } } if (lLogisticsControlTable.APMPriorityId) select count(recId) from lLogisticsControlTable where lLogisticsControlTable.APMPriorityId == newVanId; counter = lLogisticsControlTable.RecId; while select lLogisticsControlTable where lLogisticsControlTable.APMPriorityId == newVanId { cnt++; if(lLogisticsControlTable.APMPriorityId == newVanId && cnt <= counter) { element.execute(3); element.send(lLogisticsControlTable); } } } } return true; }

  • Issue with getting 2 chars from string using indexer

    - by Learner
    I am facing an issue in reading char values. See my program below. I want to evaluate an infix expression. As you can see I want to read '10' , '*', '20' and then use them...but if I use string indexer s[0] will be '1' and not '10' and hence I am not able to get the expected result. Can you guys suggest me something? Code is in c# class Program { static void Main(string[] args) { string infix = "10*2+20-20+3"; float result = EvaluateInfix(infix); Console.WriteLine(result); Console.ReadKey(); } public static float EvaluateInfix(string s) { Stack<float> operand = new Stack<float>(); Stack<char> operator1 = new Stack<char>(); int len = s.Length; for (int i = 0; i < len; i++) { if (isOperator(s[i])) // I am having an issue here as s[i] gives each character and I want the number 10 operator1.Push(s[i]); else { operand.Push(s[i]); if (operand.Count == 2) Compute(operand, operator1); } } return operand.Pop(); } public static void Compute(Stack<float> operand, Stack<char> operator1) { float operand1 = operand.Pop(); float operand2 = operand.Pop(); char op = operator1.Pop(); if (op == '+') operand.Push(operand1 + operand2); else if(op=='-') operand.Push(operand1 - operand2); else if(op=='*') operand.Push(operand1 * operand2); else if(op=='/') operand.Push(operand1 / operand2); } public static bool isOperator(char c) { bool result = false; if (c == '+' || c == '-' || c == '*' || c == '/') result = true; return result; } } }

  • PHP Variable with Array

    - by Crays
    Hi guys, i'm trying to make a "update user's power" page. It is something similar to those you can find in say, invisionfree forums. I need it to generate a list of members with checkbox [done] Add an option for it [done] What i don't know how to do is to update, to say, give all the selected users the selected power. Then i went searching for something and found most of them uses array to do this, but i never found one that actually explains how it works. The example i took (with my own modification) was this: while($row = mysql_fetch_array($result)) { echo '<tr>'.$id[]=$rows['id'].''; echo '<td width="50px" align="center" class="TableFormCell"><input type="checkbox" name="option[]" /></td>'; echo '<td width="170px" align="center" class="TableFormCell">'.$row['uname'].'</td>'; echo '</tr>'; } I'm not sure what exactly $id[]=$rows['id'] does I know after the row, my option[] would become an array of option[1], option[2], option[3] for what power should be given, i've got no problem with that but on how to update the database i'm got no clue... for($i=0;$i<$count;$i++){ $sql1="UPDATE ninos SET power='$power' WHERE id='$option[$i]'"; $result1=mysql_query($sql1); } So Say i have 5 users, Aye, Bee, Cee, Dee, Eee with IDs of 1,2,3,4,5 how can i make it so that my script would run like $sql1="UPDATE ninos SET power = '$power' Where id='1','2','3','4','5'"; Please help, thanks.

  • How to get the ui:param value in Javabean

    - by mihaela
    Hello, I am learning facelets and Seam and I'm facing the following problem: I'm have 2 xhtml files, one includes the other and each one has its own Seam component as backing bean. I want to send and object to the included facelet and obtain that object in the backing bean corresponding to the included facelet. I'll take an example to explain better the situation: registration.xhtml with Seam component as backing bean Registration.java. In this class I have an object of type Person address.html with Seam component as backing bean Address.java. In this class i want to obtain the Person object from the Registration component and set the address. registration.xhtml includes the address.xhtml and passes an object using How to obtain this object in Address bean? Will be the same reference of the object from the Registration bean? is the solution of passing this object or there is another solution for that? (maybe f:attribute, but even in this case how do I obtain the object in bean) This example is simple and not necessarily realistic but I have a similar problem and I don't know how to solve it. Thanks in advance.

  • Addind the sum of numbers using a loop statement

    - by Deonna
    I need serious help diving the positive numbers and the negative numbers. I am to accumulate the total of the negative values and separately accumulate the total of the positive values. After the loop, you are then to display the sum of the negative values and the sum of the positive values. The data is suppose to look like this: -2.3 -1.9 -1.5 -1.1 -0.7 -0.3 0.1 0.5 0.9 1.3 1.7 2.1 2.5 2.9 Sum of negative values: -7.8 Sum of positive values: 12 So far I have this: int main () { int num, num2, num3, num4, num5, sum, count, sum1; int tempVariable = 0; int numCount = 100; int newlineCount = 0, newlineCount1 = 0; float numCount1 = -2.3; while (numCount <= 150) { cout << numCount << " "; numCount += 2; newlineCount ++; if(newlineCount == 6) { cout<< " " << endl; newlineCount = 0; } } **cout << "" << endl; while (numCount1 <=2.9 ) { cout << numCount1 << " "; numCount1 += 0.4; newlineCount1 ++; } while ( newlineCount1 <= 0 && newlineCount >= -2.3 ); cout << "The sum is " << newlineCount1 << endl;** return 0; }

  • How to get rid of void-pointers.

    - by Patrick
    I inherited a big application that was originally written in C (but in the mean time a lot of C++ was also added to it). Because of historical reasons, the application contains a lot of void-pointers. Before you start to choke, let me explain why this was done. The application contains many different data structures, but they are stored in 'generic' containers. Nowadays I would use templated STL containers for it, or I would give all data structures a common base class, so that the container can store pointers to the base class, but in the [good?] old C days, the only solution was to cast the struct-pointer to a void-pointer. Additionally, there is a lot of code that works on these void-pointers, and uses very strange C constructions to emulate polymorphism in C. I am now reworking the application, and trying to get rid of the void-pointers. Adding a common base-class to all the data structures isn't that hard (few days of work), but the problem is that the code is full of constructions like shown below. This is an example of how data is stored: void storeData (int datatype, void *data); // function prototype ... Customer *myCustomer = ...; storeData (TYPE_CUSTOMER, myCustomer); This is an example of how data is fetched again: Customer *myCustomer = (Customer *) fetchData (int datatype, char *key); I actually want to replace all the void-pointers with some smart-pointer (reference-counted), but I can't find a trick to automate (or at least) help me to get rid of all the casts to and from void-pointers. Any tips on how to find, replace, or interact in any possible way with these conversions?

  • Quick help refactoring Ruby Class

    - by mplacona
    I've written this class that returns feed updates, but am thinking it can be further improved. It's not glitchy or anything, but as a new ruby developer, I reckon it's always good to improve :-) class FeedManager attr_accessor :feed_object, :update, :new_entries require 'feedtosis' def initialize(feed_url) @feed_object = Feedtosis::Client.new(feed_url) fetch end def fetch @feed_object.fetch end def update @updates = fetch end def updated? @updates.new_entries.count > 0 ? true : false end def new_entries @updates.new_entries end end As you can see, it's quite simple, but the things I'm seeing that aren't quite right are: Whenever I call fetch via terminal, it prints a list with the updates, when it's really supposed return an object. So as an example, in the terminal if I do something like: client = Feedtosis::Client.new('http://stackoverflow.com/feeds') result = client.fetch I then get: <Curl::Easy http://stackoverflow.com/feeds> Which is exactly what I'd expect. However, when doing the same thing with "inniting" class with: FeedManager.new("http://stackoverflow.com/feeds") I'm getting the object returning as an array with all the items on the feed. Sure I'm doing something wrong, so any help refactoring this class will he greatly appreciated. Also, I'd like to see comments about my implementation, as well as any sort of comment to make it better would be welcome. Thanks in advance

  • JAAS and WebLogic 10.3: Granting specific codebase permissions to a JAR bundled within an EAR

    - by Jason
    Here's my scenario: I have a JAR within the APP-INF/lib of my EAR, to be deployed within WebLogic 10g Release 3 against which I wish to grant specific permissions. e.g., grant codebase "file:/c:/somedir/my.jar" { permission java.net.SocketPermission "*:-","accept,connect,listen, resolve"; permission java.net.SocketPermission "localhost:-","accept,connect,listen,resolve"; permission java.net.SocketPermission "127.0.0.1:-","accept,connect,listen,resolve"; permission java.net.SocketPermission "230.0.0.1:-","accept,connect,listen,resolve"; permission java.util.PropertyPermission "*", "read,write"; permission java.lang.RuntimePermission "*"; permission java.io.FilePermission "<<ALL FILES>>","read,write,delete"; permission javax.security.auth.AuthPermission "*"; permission java.security.SecurityPermission "*"; }; Questions: Where is the best place to define this grant - in the java.policy of the JRE, WL server's weblogic.policy, or within a XML packaged within the EAR How do I define the codebase URL to the JAR? The examples I have seen have an explicit reference to the JAR on the file system, however I am deploying the JAR packaged up within an EAR. Thanks!

  • ASP.NET MVC and NHibernate coupling

    - by Ben
    I have just started learning NHibernate. Over the past few months I have been using IoC / DI (structuremap) and the repository pattern and it has made my applications much more loosely coupled and easier to test. When switching my persistence layer to NHibernate I decided to stick with my repositories. Currently I am creating a new session on each method call but of course this means that I can not benefit from lazy loading. Therefore I wish to implement session-per-request but in doing so this will make my web project dependent on NHibernate (perhaps this is not such a bad thing?). I was planning to inject ISession into my repositories and create and dispose sessions on beginrequest/endrequest events (see http://ayende.com/Blog/archive/2009/08/05/do-you-need-a-framework.aspx) Is this a good approach? Presumably I cannot use session-per-request without having a reference to NHibernate in my web project? Having the web project dependent on NHibernate prompts my next (few) questions - why even bother with the repository? Since my web app is calling services that talk to the repositories, why not ditch the repositories and just add my NHibernate persistance code inside the services? And finally, is there really any need to split out into so many projects. Is a web project and an infrastructure project sufficient? I realise that I have veered off a bit from my original question but it seems that everyone seems to have their own opinion on these topics. Some people use the repository pattern with NHibernate, some don't. Some people stick their mapping files with the related classes, others have a separate project for this. Many thanks, Ben

  • trackPageView on Google Analytics for iPhone Not Working

    - by DigitalZombieKid
    I'm trying to get Google Analytics working on an iPhone application without much luck. I've followed all the instructions on their website (google/apis/analytics/docs/tracking/mobileAppsTracking.html) and studied their sample application (google/gaformobileapps/GoogleAnalyticsIphone_0.7.tar.gz). When I run my application and go to Google Analytics' website (https://www.google.com/analytics/reporting/), the only page that is recording is /app_entry_point. I'm seeing one count in my Google Analytics detailed report once every time my app fires up. However, I have added other pages to be tracked but it's not working. Here is a sample of two pages I've added to be tracked: trackPageview:@"/calculator"; trackPageview:@"/tellafriend"; I call them from various ViewControllers in the app. In each of those view controllers I import the the GANTracker header: #import "GANTracker.h" I'll admit it: I'm an objective-c newbie. Any help you can offer is greatly appreciated! Do I need to physically dispatch them to get the trackPageview working? If so, why is the /app_entry_point page the only page that is recorded by Google Analytics?

  • String to array or Array to string tips on formats, etc

    - by user316841
    hi, first of all thanks for taking your time! I'm a junior Dev, working with PHP + mysql. My issue: I'm saving data from a form to my database. From this form, there's only need to save the contacts: Name, phone number, address. But, it would be nice to have a small reference to the user answers. Let's say for each question we've got a value betwee 1 and 4. Since there's no need to create a table just for it, because what's needed is just the personal contacts. I'm thinking of recording each question/answer, as a letter and its correspondent value. Example (A2, B1, C5, D3, etc). My question is: Is there a format I could afterwards, handle easily ? Convert to array (string to array) in case the client change ideas, and ask this data, placed in table columns ? Just to prevent this situation! Example, From (A2, B1, C5 ) to array( "A" = "1", "B" = "1", "C" = "5" ) For now I guess, Regex is the answer, but it's allways hard to figure it out and I'm allways getting in troubles =) Thanks!

  • Pros/Cons of MySQL vs Postgresql for production Ruby on Rails environment?

    - by cakeforcerberus
    I will soon be switching from sqlite3 to either postgres or mysql. What should I consider when making this decision? Is mysql more suited for Rails than postgres in some areas and/or vice versa? Or, as I somewhat suspect, does it not really matter either way? Another factor that might play into my decision is the availability of tools to data pump my test data from the sqlite3 db to my new one. Is there anything that ActiveRecord provides natively to do this or any decent plugins/gems to help with this task? BONUS: How do I pronounce "Postgresql" and sound like I know what I'm talking about? :) Thanks Greg Smith for providing the following link that shows the most common pronunciations: http://www.postgresql.org/community/survey.33 UPDATE: Reference this question for more: http://stackoverflow.com/questions/110927/do-you-recommend-postgresql-over-mysql FYI: I ended up using MySQL. There is a neat plugin called yamldb that really saved me some time with the data transfer from my sqlite db to my new mysql one. Instructions on how to install and use it can be found here: http://accidentaltechnologist.com/ruby/change-databases-in-rails-with-yamldb/ Thanks Tom

  • Matlab and .net problem with character string function input

    - by Peter
    I have a MATLAB function that I've compiled into a .net library. The function is a simple one that takes a character array as an input and a numeric array as output: function insert = money(dateLimit) .. insert = [1 2]; The function works fine when no function arguments are specified (a default argument is provided inside the function) Dim sf As New SpreadFinder.SpreadFinder Dim output = sf.money() As soon as an argument is specified .net complains. I'm thinking this should be easy and has been done before but searching through MATLAB documentation doesn't offer much help. Here's what I've tried. The sf.money() overload for the function with arguments is (numArgsOut as Integer, argsOut as MWArray, argsIn as MWArray) and hence that's what I've tried. What am I missing? Dim sf As New SpreadFinder.SpreadFinder Dim inputArgs(1) As Arrays.MWCharArray Dim dateLimitString As String = "some string" inputArgs(0) = New Arrays.MWCharArray(dateLimitString) Dim outputArgs(1) As Arrays.MWNumericArray outputArgs(0) = New Arrays.MWNumericArray() sf.money(1, outputArgs, inputArgs) Gives System.NullReferenceException : Object reference not set to an instance of an object. at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, Int32 numArgsIn, MWArray[] argsIn) at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, MWArray[]& argsOut, MWArray[] argsIn) at SpreadFinder.SpreadFinder.money(Int32 numArgsOut, MWArray[]& argsOut, MWArray[] argsIn)

  • Output iterator's value_type

    - by wilhelmtell
    The STL commonly defines an output iterator like so: template<class Cont> class insert_iterator : public iterator<output_iterator_tag,void,void,void,void> { // ... Why do output iterators define value_type as void? It would be useful for an algorithm to know what type of value it is supposed to output. For example, a function that translates a URL query "key1=value1&key2=value2&key3=value3" into any container that holds key-value strings elements. template<typename Ch,typename Tr,typename Out> void parse(const std::basic_string<Ch,Tr>& str, Out result) { std::basic_string<Ch,Tr> key, value; // loop over str, parse into p ... *result = typename iterator_traits<Out>::value_type(key, value); } The SGI reference page of value_type hints this is because it's not possible to dereference an output iterator. But that's not the only use of value_type: I might want to instantiate one in order to assign it to the iterator.

  • bitset to dynamic bitset

    - by mr.bio
    Hi.. I have a function where i use bitset.Now i need to convert it to a dynamic bitset.. but i don't know how. Can somebody help me ? set<string> generateCandidates(set<string> ck,unsigned int k){ set<string> nk ; for (set<string>::const_iterator p = ck.begin( );p != ck.end( ); ++p){ for (set<string>::const_iterator q = ck.begin( );q != ck.end( ); ++q){ bitset<4> bs1(*p); bitset<4> bs2(*q); bs1|= bs2 ; if(bs1.count() == k){ nk.insert(bs1.to_string<char,char_traits<char>,allocator<char> >()); } } } return nk; }
