  • Passing variables to shopping cart with Javascript

    - by albatross
    This question is an extension of this one: http://stackoverflow.com/questions/2359238/calculate-order-price-by-date-selection-value I'm trying to make a conference registration page based off the previous page, which passes the variables(name, email, price) to my organization's outdated shopping cart using javascript. I'm also using Seminar Registration by CSSTricks (http://css-tricks.com/examples/SeminarRegTutorial/) Currently, my proceed to payment button produces an 'element is undefined' error on line 298(same thing on unresolved previous question, linked above^): switch (document.Information.amount.value) { Any help would be greatly appreciated. I'm at my wits end with this.

  • .NET - getting form field key/value pairs?

    - by AverageJoe719
    Hi there, I've got a form with textboxes and I want to run some server side validation code on the values after the form is submitted. I was planning to grab all the textbox controls on the page and adding them to a list, then running a for each loop that says for each control in the list query the database where fieldValidation.Name = Control.Name. This would return to me an object and an associated function where i coudl then input the Control.Value and actually perform the validation. My friend told me building the list is not necessary because all languages have a way to get key/value pairs from forms (he doesn't know .NET so coudln't help me). I may be searching the wrong term here but I have not been able to find a result, or maybe I misunderstood my friend. Is there some kind of dictionary or key/value pair automatically generated upon form submissions that contains the value that was submitted and...I guess also the control? Or am I just misunderstanding him. If he was just saying populate a key/value pair based on the form submissions, how does that help me in this situation over a list that contains the control? Thanks =)

  • JQuery returns wrong value for IE Compatibility

    - by o-logn
    Hey , I'm using JQuery and there seems to be a problem when I run IE in compatibility mode (and generally any IE less than version 8). I'm trying to use attr("value") for a button control. In IE8, and other browsers, this works fine and the result of this code: alert($(this).attr("value")); is simply the value of set in the button attribute (e.g. Home, Settings, Help etc..) However, when this is run in IE compatibility view, I get the entire HTML as the output value: <SPAN class=ui-button-text>Home</SPAN> This causes my checks to fail. Is there a way to return just the Home section across all browsers? Thanks

  • Can a single argument constructor with a default value be subject to implicit type conversion

    - by Richard
    I understand the use of the explicit keyword to avoid the implicit type conversions that can occur with a single argument constructor, or with a constructor that has multiple arguments of which only the first does not have a default value. However, I was wondering, does a single argument constructor with a default value behave the same as one without a default value when it comes to implicit conversions?

  • MySQL: Auto-increment value: 0 is smaller than max used value: xx

    - by Rhodri
    Increasingly I'm getting tables having to be repaired dwith the message returned of: Auto-increment value: 0 is smaller than max used value: xx This has happened on tables with 200 rows and tables with ~3 million rows, but so far the same few tables have had the problem. I'm running MySQL 5.0.22. The repairs are run by a script which checks every minute for the need to repair MySQL tables. I also have an automated backup of the 6 Gigabyte database running very two hours and the repairs always get trigged around the time of the backup. Any ideas?

  • How do you manage all of the information you have learned and found? [closed]

    - by B Seven
    Possible Duplicate: How do you manage your knowledge base? What do you use for personal note taking to keep track of everything you learn? Are you always Googling or searching StackOverflow to answer the same questions? Or searching for and copying and pasting existing code? I feel like I have a poor memory, especially remembering things like syntax. Are there any knowledge management systems that would work well for a programming language or operating system? It would be great if there were a way to save everything I learn in an easy to search system. Does such a thing exist? Maybe you would be able to search by question (How to sort an array?, How to set static IP?), or by tag (sort, array, enumeration, iterator, IP). I know it would be easy to develop my own system, but I thought it would be great to learn what works for other people.

  • Gaining information from nodes of tree

    - by jainp
    I am working with the tree data structure and trying to come up with a way to calculate information I can gain from the nodes of the tree. I am wondering if there are any existing techniques which can assign higher numerical importance to a node which appears less frequently at lower level (Distance from the root of the tree) than the same nodes appearance at higher level and high frequency. To give an example, I want to give more significance to node Book, at level 2 appearing once, then at level 3 appearing thrice. Will appreciate any suggestions/pointers to techniques which achieve something similar. Thanks, Prateek

  • Extracting Demographic and Contact Information from unstructured text files

    - by jn29098
    I am looking to extract specific items out of a large pool of unstructured documents. These documents could be 1-5 pages of text formatted in various ways by the user, but in most cases would contain at least: Name Address (physical) Email Address Phone number website URL I'm looking for a semantic parser that can attempt to extract these elements from the documents so that I can load that information into a relational database and work with these records as contacts. Other services I've looked for, while valuable for other purposes, do not address this specific need. Alchemy API Open Calais Saplo Any thoughts, suggestions or leads?

  • Display System Information on Your Desktop with Desktop Info

    - by Asian Angel
    Do you like to monitor your system but do not want a complicated app to do it with? If you love simplicity and easy configuration then join us as we look at Desktop Info. Desktop Info in Action Desktop Info comes in a zip file format so you will need to unzip the app, place it into an appropriate “Program Files Folder”, and create a shortcut. Do NOT delete the “Read Me File”…this will be extremely useful to you when you make changes to the “Configuration File”. Once you have everything set up you are ready to start Desktop Info up. This is the default layout and set of listings displayed when you start Desktop Info up for the first time. The font colors will be a mix of colors as seen here and the font size will perhaps be a bit small but those are very easy to change if desired. You can access the “Context Menu” directly over the “information area”…so no need to look for it in the “System Tray”. Notice that you can easily access that important “Read Me File” from here… The full contents of the configuration file (.ini file) are displayed here so that you can see exactly what kind of information can be displayed using the default listings. The first section is “Options”…you will most likely want to increase the font size while you are here. Then “Items”… If you are unhappy with any of the font colors in the “information area” this is where you can make the changes. You can turn information display items on or off here. And finally “Files, Registry, & Event Logs”. Here is our displayed information after a few tweaks in the configuration file. Very nice. Conclusion If you have been looking for a system information app that is simple and easy to set up then you should definitely give Desktop Info a try.

  • What mail storage should I choose for our web application; IMAP, key-valud store, rdbms, ...

    - by tvrtko
    I have to store e-mail messages for use with our application. I have "metadata" for all messages inside a relational database, but I don't feel comfortable keeping message content (gigabytes and terabytes of email data) inside a database. I'm currently using IMAP as a storage, but I have my doubts if I choose correctly. First of all there is a problem of uidvalidity and how to keep a permanent reference to message inside IMAP. Second, I'm not sure if this is the most robust solution in terms of backup/restore strategies, corruption of store, replication ... Positive side is that I can query IMAP using the headers because the data is mostly indexed. I don't know if key-value stores are a better approach (Casandra, Tokyo cabinet, redis). How they handle storing 1KB and 50MB of data. How they prevent corruption and when corruption or device failure happens how can I repair the store.

  • Joy! | Important Information About Your iPad 3G

    - by Jeff Julian
    Looks like I was one of the lucky 114,000 who AT&T lost their email to “hackers”.  Why is “hackers” in “double quotes”.  I can just imagine some executive at AT&T in their “Oh No, We Messed Up Meeting” saying, what happened?  Then someone replied, well we have had a breach and “hackers” broke in (using the quote in the air gesture) and stole our iPad 3G customers emails. Oh well, I am sure my email has been sold and sold again by many different vendors, why not AT&T now.  At least Dorothy Attwood could have gave us her email to give to someone else instead of blinking it through a newsletter system. June 13, 2010 Dear Valued AT&T Customer, Recently there was an issue that affected some of our customers with AT&T 3G service for iPad resulting in the release of their customer email addresses. I am writing to let you know that no other information was exposed and the matter has been resolved.  We apologize for the incident and any inconvenience it may have caused. Rest assured, you can continue to use your AT&T 3G service on your iPad with confidence. Here’s some additional detail: On June 7 we learned that unauthorized computer “hackers” maliciously exploited a function designed to make your iPad log-in process faster by pre-populating an AT&T authentication page with the email address you used to register your iPad for 3G service.  The self-described hackers wrote software code to randomly generate numbers that mimicked serial numbers of the AT&T SIM card for iPad – called the integrated circuit card identification (ICC-ID) – and repeatedly queried an AT&T web address.   When a number generated by the hackers matched an actual ICC-ID, the authentication page log-in screen was returned to the hackers with the email address associated with the ICC-ID already populated on the log-in screen. The hackers deliberately went to great efforts with a random program to extract possible ICC-IDs and capture customer email addresses.  They then put together a list of these emails and distributed it for their own publicity. As soon as we became aware of this situation, we took swift action to prevent any further unauthorized exposure of customer email addresses.  Within hours, AT&T disabled the mechanism that automatically populated the email address. Now, the authentication page log-in screen requires the user to enter both their email address and their password. I want to assure you that the email address and ICC-ID were the only information that was accessible. Your password, account information, the contents of your email, and any other personal information were never at risk.  The hackers never had access to AT&T communications or data networks, or your iPad.  AT&T 3G service for other mobile devices was not affected. While the attack was limited to email address and ICC-ID data, we encourage you to be alert to scams that could attempt to use this information to obtain other data or send you unwanted email. You can learn more about phishing by visiting the AT&T website. AT&T takes your privacy seriously and does not tolerate unauthorized access to its customers’ information or company websites.   We will cooperate with law enforcement in any investigation of unauthorized system access and to prosecute violators to the fullest extent of the law. AT&T acted quickly to protect your information – and we promise to keep working around the clock to keep your information safe.  Thank you very much for your understanding, and for being an AT&T customer. Sincerely, Dorothy Attwood Senior Vice President, Public Policy and Chief Privacy Officer for AT&T Technorati Tags: AT&T,iPad 3G,Email

  • Consumer Oriented Search In Oracle Endeca Information Discovery - Part 2

    - by Bob Zurek
    As discussed in my last blog posting on this topic, Information Discovery, a core capability of the Oracle Endeca Information Discovery solution enables businesses to search, discover and navigate through a wide variety of big data including structured, unstructured and semi-structured data. With search as a core advanced capabilities of our product it is important to understand some of the key differences and capabilities in the underlying data store of Oracle Endeca Information Discovery and that is our Endeca Server. In the last post on this subject, we talked about Exploratory Search capabilities along with support for cascading relevance. Additional search capabilities in the Endeca Server, which differentiate from simple keyword based "search boxes" in other Information Discovery products also include: The Endeca Server Supports Set Search.  The Endeca Server is organized around set retrieval, which means that it looks at groups of results (all the documents that match a search), as well as the relationship of each individual result to the set. Other approaches only compute the relevance of a document by comparing the document to the search query – not by comparing the document to all the others. For example, a search for “U.S.” in another approach might match to the title of a document and get a high ranking. But what if it were a collection of government documents in which “U.S.” appeared in many titles, making that clue less meaningful? A set analysis would reveal this and be used to adjust relevance accordingly. The Endeca Server Supports Second-Order Relvance. Unlike simple search interfaces in traditional BI tools, which provide limited relevance ranking, such as a list of results based on key word matching, Endeca enables users to determine the most salient terms to divide up the result. Determining this second-order relevance is the key to providing effective guidance. Support for Queries and Filters. Search is the most common query type, but hardly complete, and users need to express a wide range of queries. Oracle Endeca Information Discovery also includes navigation, interactive visualizations, analytics, range filters, geospatial filters, and other query types that are more commonly associated with BI tools. Unlike other approaches, these queries operate across structured, semi-structured and unstructured content stored in the Endeca Server. Furthermore, this set is easily extensible because the core engine allows for pluggable features to be added. Like a search engine, queries are answered with a results list, ranked to put the most likely matches first. Unlike “black box” relevance solutions, which generalize one strategy for everyone, we believe that optimal relevance strategies vary across domains. Therefore, it provides line-of-business owners with a set of relevance modules that let them tune the best results based on their content. The Endeca Server query result sets are summarized, which gives users guidance on how to refine and explore further. Summaries include Guided Navigation® (a form of faceted search), maps, charts, graphs, tag clouds, concept clusters, and clarification dialogs. Users don’t explicitly ask for these summaries; Oracle Endeca Information Discovery analytic applications provide the right ones, based on configurable controls and rules. For example, the analytic application might guide a procurement agent filtering for in-stock parts by visualizing the results on a map and calculating their average fulfillment time. Furthermore, the user can interact with summaries and filters without resorting to writing complex SQL queries. The user can simply just click to add filters. Within Oracle Endeca Information Discovery, all parts of the summaries are clickable and searchable. We are living in a search driven society where business users really seem to enjoy entering information into a search box. We do this everyday as consumers and therefore, we have gotten used to looking for that box. However, the key to getting the right results is to guide that user in a way that provides additional Discovery, beyond what they may have anticipated. This is why these important and advanced features of search inside the Endeca Server have been so important. They have helped to guide our great customers to success.

  • iPhone Key-Value Observer: observer not registering in UITableViewController

    - by Scott
    Hi Fellow iPhone Developers, I am an experienced software engineer but new to the iPhone platform. I have successfully implemented sub-classed view controllers and can push and pop parent/child views on the view controller stack. However, I have struck trouble while trying to update a view controller when an object is edited in a child view controller. After much failed experimentation, I discovered the key-value observer API which looked like the perfect way to do this. I then registered an observer in my main/parent view controller, and in the observer I intend to reload the view. The idea is that when the object is edited in the child view controller, this will be fired. However, I think that the observer is not being registered, because I know that the value is being updated in the editing view controller (I can see it in the debugger), but the observing method is never being called. Please help! Code snippets follow below. Object being observed. I believe that this is key-value compliant as the value is set when called with the setvalue message (see Child View Controller below). X.h: @interface X : NSObject <NSCoding> { NSString *name; ... @property (nonatomic, retain) NSString *name; X.m: @implementation X @synthesize name; ... Main View Controller.h: @class X; @interface XViewController : UITableViewController { X *x; ... Main View Controller.m: @implementation XViewController @synthesize x; ... - (void)viewDidLoad { ... [self.x addObserver:self forKeyPath: @"name" options: (NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld) context:nil]; [super viewDidLoad]; } ... - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if ([keyPath isEqual:@"name"]) { NSLog(@"Found change to X"); [self.tableView reloadData]; } [super observeValueForKeyPath:keyPath ofObject:object change:change context:context]; } Child View Controller.m: (this correctly sets the value in the object in the child view controller) [self.x setValue:[[tempValues objectForKey:key] text] forKey:@"name"];

  • Setting up a "to-many" relationship value dependency for a transient Core Data attribute

    - by Greg Combs
    I've got a relatively complicated Core Data relationship structure and I'm trying to figure out how to set up value dependencies (or observations) across various to-many relationships. Let me start out with some basic info. I've got a classroom with students, assignments, and grades (students X assignments). For simplicity's sake, we don't really have to focus much on the assignments yet. StudentObj <--->> ScoreObj <<---> AssignmentObj Each ScoreObj has a to-one relation with the StudentObj and the AssignmentObj. ScoreObj has real attributes for the numerical grade, the turnInDate, and notes. AssignmentObj.scores is the set of Score objects for that assignment (N = all students). AssignmentObj has real attributes for name, dueDate, curveFunction, gradeWeight, and maxPoints. StudentObj.scores is the set of Score objects for that student (N = all assignments). StudentObj also has real attributes like name, studentID, email, etc. StudentObj has a transient (calculated, not stored) attribute called gradeTotal. This last item, gradeTotal, is the real pickle. it calculates the student's overall semester grade using the scores (ScoreObj) from all their assignments, their associated assignment gradeWeights, curves, and maxPoints, and various other things. This gradeTotal value is displayed in a table column, along with all the students and their individual assignment grades. Determining the value of gradeTotal is a relatively expensive operation, particularly with a large class, therefore I want to run it only when necessary. For simplicity's sake, I'm not storing that gradeTotal value in the core data model. I don't mind caching it somewhere, but I'm having a bitch of a time determining where and how to best update that cache. I need to run that calculation for each student whenever any value changes that affects their gradeTotal. If this were a simple to-one relationship, I know I could use something like keyPathsForValuesAffectingGradeTotal ... but it's more like a many-to-one-to-many relationship. Does anyone know of an elegant (and KVC correct) solution? I guess I could tear through all those score and assignment objects and tell them to register their students as observers. But this seems like a blunt force approach.

  • Javascript wont change value in TextBox

    - by mattgcon
    Here is my javascript function AppendValues(e) { var lghtcnt = 0; var vars = e.id.split(';'); var highcnt = false; var lghtid = ""; var maxltcnt = 100; for (var x = 0; x < vars.length; x++) { var tokens = vars[x].split('|'); var pram = tokens if (tokens[0] == "ID"){ lghtid = tokens[1]; } if (tokens[0] == "LTC"){ var itemcnt = 0; var currentcnt = 0; currentcnt = parseInt(tokens[1].toString()); var txtid = document.getElementById(vars[0] + ';' + vars[1] + ';' + vars[2] + ';' + vars[3] + ';' + vars[4]); if (e.checked) { totallightcnt += currentcnt; if (totallightcnt > maxltcnt) { document.getElementById(vars[0] + ';' + vars[1] + ';' + vars[2] + ';' + vars[3] + ';' + vars[4]).value = 0; alert('This puts you over the limit of 100 total lights, please make adjustments.'); break; } document.getElementById(vars[0] + ';' + vars[1] + ';' + vars[2] + ';' + vars[3] + ';' + vars[4]).value = currentcnt.toString(); } else { totallightcnt -= currentcnt; document.getElementById(vars[0] + ';' + vars[1] + ';' + vars[2] + ';' + vars[3] + ';' + vars[4]).value = 0; break; } } if (highcnt) { break; } } } Here is the issue, when I check the value it DOES say theupdated value but it does not display to the user on the webpage. What could be the issue?

  • NHibernate and objects with value-semantics

    - by Groo
    Problem: If I pass a class with value semantics (Equals method overridden) to NHibernate, NHibernate tries to save it to db even though it just saved an entity equal by value (but not by reference) to the database. What am I doing wrong? Here is a simplified example model for my problem: Let's say I have a Person entity and a City entity. One thread (producer) is creating new Person objects which belong to a specific existing City, and another thread (consumer) is saving them to a repository (using NHibernate as DAL). Since there is lot of objects being flushed at a time, I am using Guid.Comb id's to ensure that each insert is made using a single SQL command. City is an object with value-type semantics (equal by name only -- for this example purposes only): public class City : IEquatable<City> { public virtual Guid Id { get; private set; } public virtual string Name { get; set; } public virtual bool Equals(City other) { if (other == null) return false; return this.Name == other.Name; } public override bool Equals(object obj) { return Equals(obj as City); } public override int GetHashCode() { return this.Name.GetHashCode(); } } Fluent NH mapping is something like: public class PersonMap : ClassMap<Person> { public PersonMap() { Id(x => x.Id) .GeneratedBy.GuidComb(); References(x => x.City) .Cascade.SaveUpdate(); } } public class CityMap : ClassMap<City> { public CityMap() { Id(x => x.Id) .GeneratedBy.GuidComb(); Map(x => x.Name); } } Right now (with my current NHibernate mapping config), my consumer thread maintains a dictionary of cities and replaces their references in incoming person objects (otherwise NHibernate will see a new, non-cached City object and try to save it as well), and I need to do it for every produced Person object. Since I have implemented City class to behave like a value type, I hoped that NHibernate would compare Cities by value and not try to save them each time -- i.e. I would only need to do a lookup once per session and not care about them anymore. Is this possible, and if yes, what am I doing wrong here?

  • non-copyable objects and value initialization: g++ vs msvc

    - by R Samuel Klatchko
    I'm seeing some different behavior between g++ and msvc around value initializing non-copyable objects. Consider a class that is non-copyable: class noncopyable_base { public: noncopyable_base() {} private: noncopyable_base(const noncopyable_base &); noncopyable_base &operator=(const noncopyable_base &); }; class noncopyable : private noncopyable_base { public: noncopyable() : x_(0) {} noncopyable(int x) : x_(x) {} private: int x_; }; and a template that uses value initialization so that the value will get a known value even when the type is POD: template <class T> void doit() { T t = T(); ... } and trying to use those together: doit<noncopyable>(); This works fine on msvc as of VC++ 9.0 but fails on every version of g++ I tested this with (including version 4.5.0) because the copy constructor is private. Two questions: Which behavior is standards compliant? Any suggestion of how to work around this in gcc (and to be clear, changing that to T t; is not an acceptable solution as this breaks POD types). P.S. I see the same problem with boost::noncopyable.

  • Overloading stream insertion without violating information hiding?

    - by Chris
    I'm using yaml-cpp for a project. I want to overload the << and >> operators for some classes, but I'm having an issue grappling with how to "properly" do this. Take the Note class, for example. It's fairly boring: class Note { public: // constructors Note( void ); ~Note( void ); // public accessor methods void number( const unsigned long& number ) { _number = number; } unsigned long number( void ) const { return _number; } void author( const unsigned long& author ) { _author = author; } unsigned long author( void ) const { return _author; } void subject( const std::string& subject ) { _subject = subject; } std::string subject( void ) const { return _subject; } void body( const std::string& body ) { _body = body; } std::string body( void ) const { return _body; } private: unsigned long _number; unsigned long _author; std::string _subject; std::string _body; }; The << operator is easy sauce. In the .h: YAML::Emitter& operator << ( YAML::Emitter& out, const Note& v ); And in the .cpp: YAML::Emitter& operator << ( YAML::Emitter& out, const Note& v ) { out << v.number() << v.author() << v.subject() << v.body(); return out; } No sweat. Then I go to declare the >> operator. In the .h: void operator >> ( const YAML::Node& node, Note& note ); But in the .cpp I get: void operator >> ( const YAML::Node& node, Note& note ) { node[0] >> ? node[1] >> ? node[2] >> ? node[3] >> ? return; } If I write things like node[0] >> v._number; then I would need to change the CV-qualifier to make all of the Note fields public (which defeats everything I was taught (by professors, books, and experience))) about data hiding. I feel like doing node[0] >> temp0; v.number( temp0 ); all over the place is not only tedious, error-prone, and ugly, but rather wasteful (what with the extra copies). Then I got wise: I attempted to move these two operators into the Note class itself, and declare them as friends, but the compiler (GCC 4.4) didn't like that: src/note.h:44: error: ‘YAML::Emitter& Note::operator<<(YAML::Emitter&, const Note&)’ must take exactly one argument src/note.h:45: error: ‘void Note::operator(const YAML::Node&, Note&)’ must take exactly one argument Question: How do I "properly" overload the >> operator for a class Without violating the information hiding principle? Without excessive copying?
