  • .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 =)

  • Javascript onunload form submit isn't submitting data

    - by Kevin
    I currently have form that checks if a user has unsubmitted changes when they leave the page with a function called through the onunload event. Here's the function: function saveOnExit() { var answer = confirm("You are about to leave the page. All unsaved work will be lost. Would you like to save now?"); if (answer) { document.main_form.submit(); } } And here's the form: <body onunload="saveOnExit()"> <form name="main_form" id="main_form" method="post" action="submit.php" onsubmit="saveScroll()"> <textarea name="comments"></textarea> <input type="submit" name="submit2" value="Submit!"/> </form> I'm not sure what I'm doing wrong here. The data gets submitted and saved in my database if I just press the submit button for the form. However, trying to submit the form through the onunload event doesn't result in anything being stored, from what I can tell. I've tried adding onclick alerts to the submitt button and onsubmit alerts to the form elements and I can verify that the submit button is being triggered and that the form does get submitted. However, nothing gets passed stored in the database. Any ideas as to what I'm doing wrong? Thanks.

  • How to deserialize an element as an XmlNode?

    - by mackenir
    When using Xml serialization in C#, I want to deserialize a part of my input XML to an XmlNode. So, given this XML: <Thing Name="George"> <Document> <subnode1/> <subnode2/> </Document> </Thing> I want to deserialize the Document element to an XmlNode. Below is my attempt which given the XML above, sets Document to the 'subnode1' element rather than the 'Document' element. How would I get the code to set the Document property to the Document element? using System; using System.IO; using System.Xml; using System.Xml.Serialization; [Serializable] public class Thing { [XmlAttribute] public string Name {get;set;} public XmlNode Document { get; set; } } class Program { static void Main() { const string xml = @" <Thing Name=""George""> <Document> <subnode1/> <subnode2/> </Document> </Thing>"; var s = new XmlSerializer(typeof(Thing)); var thing = s.Deserialize(new StringReader(xml)) as Thing; } } However, when I use an XmlSerializer to deserialize the XML above to an instance of Thing, the Document property contains the child element 'subnode1', rather than the 'doc' element. How can I get the XmlSerializer to set Document to an XmlNode containing the 'doc' element.

  • Can't empty JS array....

    - by solefald
    Yes, I am having issues with this very basic (or so it seems) thing. I am pretty new to JS and still trying to get my head around it, but I am pretty familiar with PHP and have never experienced anything like this. I just can not empty this damn array, and stuff keeps getting added to the end every time i run this. I have no idea why, and i am starting to think that it is somehow related to the way chekbox id's are named, but i may be mistaking.... id="alias[1321-213]", id="alias[1128-397]", id="alias[77-5467]" and so on. I have tried sticking checkboxes = []; and checkboxes.length = 0; In every place possible. Right after the beginning of the function, at the end of the function, even outside, right before the function, but it does not help, and the only way to empty this array is to reload the page. Please tell me what I am doing wrong, or at least point me to a place where i can RTFM. I am completely out of ideas here. function() { var checkboxes = new Array(); checkboxes = $(':input[name="checkbox"]'); $.each(checkboxes, function(key, value) { console.log(value.id); alert(value.id); } ); checkboxes.length = 0; } I have also read Mastering Javascript Arrays 3 times to make sure I am not doing something wrong, but still can't figure it out....

  • OdbcCommand on Stored Procedure - "Parameter not supplied" error on Output parameter

    - by Aaron
    I'm trying to execute a stored procedure (against SQL Server 2005 through the ODBC driver) and I recieve the following error: Procedure or Function 'GetNodeID' expects parameter '@ID', which was not supplied. @ID is the OUTPUT parameter for my procedure, there is an input @machine which is specified and is set to null in the stored procedure: ALTER PROCEDURE [dbo].[GetNodeID] @machine nvarchar(32) = null, @ID int OUTPUT AS BEGIN SET NOCOUNT ON; IF EXISTS(SELECT * FROM Nodes WHERE NodeName=@machine) BEGIN SELECT @ID = (SELECT NodeID FROM Nodes WHERE NodeName=@machine) END ELSE BEGIN INSERT INTO Nodes (NodeName) VALUES (@machine) SELECT @ID = (SELECT NodeID FROM Nodes WHERE NodeName=@machine) END END The following is the code I'm using to set the parameters and call the procedure: OdbcCommand Cmd = new OdbcCommand("GetNodeID", _Connection); Cmd.CommandType = CommandType.StoredProcedure; Cmd.Parameters.Add("@machine", OdbcType.NVarChar); Cmd.Parameters["@machine"].Value = Environment.MachineName.ToLower(); Cmd.Parameters.Add("@ID", OdbcType.Int); Cmd.Parameters["@ID"].Direction = ParameterDirection.Output; Cmd.ExecuteNonQuery(); _NodeID = (int)Cmd.Parameters["@Count"].Value; I've also tried using Cmd.ExecuteScalar with no success. If I break before I execute the command, I can see that @machine has a value. If I execute the procedure directly from Management Studio, it works correctly. Any thoughts? Thanks

  • Multiple WCF calls for a single ASP.NET page load

    - by Rodney Burton
    I have an existing asp.net web application I am redesigning to use a service architecture. I have the beginnings of an WCF service which I am able to call and perform functions with no problems. As far as updating data, it all makes sense. For example, I have a button that says Submit Order, it sends the data to the service, which does the processing. Here's my concern: If I have an ASP.NET page that shows me a list of orders (View Orders page), and at the top I have a bunch of drop down lists for order types, and other search criteria which is populated by querying different tables from the database (lookup tables, etc). I am hoping to eventually completely decouple the web application from the DB, and use data contracts to pass information between the BLL, the SOA, and the web app. With that said, how can I reduce the # of WCF calls needed to load my "View Orders" page? I would need to make 1 call get the list of orders, and 1 call for each drop down list, etc because those are populated by individual functions in my BLL. Is it good architecture to create a web service method that returns back a specialized data contract that consists of everything you would need to display a View Orders page, in 1 shot? Something like this pseudocode: public class ViewOrderPageDTO { public OrderDTO[] Orders { get; set; } public OrderTypesDTO[] OrderTypes { get; set; } public OrderStatusesDTO[] OrderStatuses { get; set; } public CustomerListDTO[] CustomerList { get; set; } } Or is it better practice in the page_load event to make 5 or 6 or even 15 individual calls to the SOA to get the data needed to load the page? Therefore, bypassing the need for specialized wcf methods or DTO's that conglomerate other DTO? Thanks for your input and suggestions.

  • Dropdown in PHP

    - by VP
    Hi, I am using PHP 5.2 on SUN OS server. Having problems with the following piece of code that for a drop down: echo '<form action="" method="get">'; echo '<p>Information:<br />'; echo '<select name="acctno" style="width: 100px;">'; foreach ($this->account_names as $acctno => $acctname) { echo '<option value="'.$acctno.'">'.$acctname.'</option>'; } echo '</select> <input type="submit" value="view" />'; echo '</form>'; Worked perfectly fine on Firefox and Chrome; however there is a problem with Internet Explorer. In IE the dropdown width is limited to the size i.e 100px. So only the first 15-16 characters of the account name are displayed all the time. However in chrome or firefox, even if only 15-16 characters are displayed initially, when the drop down arrow is clicked upon, it show the entire name (however long it may be). This does not happen with IE. So if the account name is, lets say, "1223456789abcdefghijkl" then: For IE: shows only "123456789" all the time Ffor chrome or firefox: shows "123456789" and when it is dropped down it show the full name as "123456789abcdefghijkl". Any help here would be much appreciated. Thanks, VP

  • How to force the build to be out of date, when a text file is modified?

    - by demoncodemonkey
    The Scenario My project has a post-build phase set up to run a batch file, which reads a text file "version.txt". The batch file uses the information in version.txt to inject the DLL with a version block using this tool. The version.txt is included in my project to make it easy to modify. It looks a bit like this: @set #Description="TankFace Utility Library" @set #FileVersion="0.1.2.0" @set #Comments="" Basically the batch file renames this file to version.bat, calls it, then renames it back to version.txt afterwards. The Problem When I modify version.txt (e.g. to increment the file version), and then press F7, the build is not seen as out-of-date, so the post-build step is not executed, so the DLL's version doesn't get updated. I really want to include the .txt file as an input to the build, but without anything actually trying to use it. If I #include the .txt file from a CPP file in the project, the compiler fails because it obviously doesn't understand what "@set" means. If I add /* ... */ comments around the @set commands, then the batch file has some syntax errors but eventually succeeds. But this is a poor solution I think. So... how would you do it?

  • WIKI replacement solution for SharePoint?

    - by Jakub
    I'm trying to research a replacement for the pathetic WIKI that comes with WSS (only wiki code it has is to create url links). I have looked at a few but most 'replacements' I see are MOSS only? (or so it just states MOSS for requirements). Has anyone faced this situation? What did you end up using? I would like something that I can have all in one location (not different apps, hence WSS). With LDAP / AD Integration like WSS. Thanks appreciate any input. I would like to see ~ $3k solutions tho (nothing super expensive, hence why we don't run MOSS). EDIT: Anyone else have any suggestions? EDIT2: Actually since I haven't had much feedback (thanks to those that have). I installed mediawiki under IIS with PHP enabled, and enabled the IIS AD hack for authentication. IIS ends up prompting for authentication (user/pass) if you use a non IE browser, then it sets the $_SERVER["REMOTE_USER"] variable, and grabs some AD info (groups etc). Works rather well, only issues is the UGLY urls so far. But its fully working. Seems like a good setup. Other than having to rely on MYSQL (my company strives to be mainly SQL Server)

  • Swing: what to do when a JTree update takes too long and freezes other GUI elements?

    - by java.is.for.desktop
    Hello, everyone! I know that GUI code in Java Swing must be put inside SwingUtilities.invokeAndWait or SwingUtilities.invokeLater. This way threading works fine. Sadly, in my situation, the GUI update it that thing which takes much longer than background thread(s). More specific: I update a JTree with about just 400 entries, nesting depth is maximum 4, so should be nothing scary, right? But it takes sometimes one second! I need to ensure that the user is able to type in a JTextPane without delays. Well, guess what, the slow JTree updates do cause delays for JTextPane during input. It refreshes only as soon as the tree gets updated. I am using Netbeans and know empirically that a Java app can update lots of information without freezing the rest of the UI. How can it be done? NOTE 1: All those DefaultMutableTreeNodes are prepared outside the invokeAndWait. NOTE 2: When I replace invokeAndWait with invokeLater the tree doesn't get updated. NOTE 3: Fond out that recursive tree expansion takes far the most time. NOTE 4: I'm using custom tree cell renderer, will try without and report. NOTE 4a: My tree cell renderer uses a map to cache and reuse created JTextComponents, depending on tree node (as a key). CLUE 1: Wow! Without setting custom cell renderer it's 10 times faster. I think, I'll need few good tutorials on writing custom tree cell renderers.

  • Treetop basic parsing and regular expression usage

    - by ucint
    I'm developing a script using the ruby Treetop library and having issues working with its syntax for regex's. First off, many regular expressions that work in other settings dont work the same in treetop. This is my grammar: (myline.treetop) grammar MyLine rule line string whitespace condition end rule string [\S]* end rule whitespace [\s]* end rule condition "new" / "old" / "used" end end This is my usage: (usage.rb) require 'rubygems' require 'treetop' require 'polyglot' require 'myline' parser = MyLineParser.new p parser.parse("randomstring new") This should find the word new for sure and it does! Now I wont to extend it so that it can find new if the input string becomes "randomstring anotherstring new yetanother andanother" and possibly have any number of strings followed by whitespace (tab included) before and after the regex for rule condition. In other words, if I pass it any sentence with the word "new" etc in it, it should be able to match it. So let's say I change my grammar to: rule line string whitespace condition whitespace string end Then, it should be able to find a match for: p parser.parse("randomstring new anotherstring") So, what do I have to do to allow the string whitespace to be repeated before and after condition? If I try to write this: rule line (string whitespace)* condition (whitespace string)* end , it goes in an infinite loop. If i replace the above () with [], it returns nil In general, regex's return a match when i use the above, but treetop regex's dont. Does anyone have any tips/points on how to go about this? Plus, since there isn't much documentation for treetop and the examples are either too trivial or too complex, is there anyone who knows a more thorough documentation/guide for treetop?

  • Variable Assignment and loops (Java)

    - by Raven Dreamer
    Greetings Stack Overflowers, A while back, I was working on a program that hashed values into a hashtable (I don't remember the specifics, and the specifics themselves are irrelevant to the question at hand). Anyway, I had the following code as part of a "recordInput" method. tempElement = new hashElement(someInt); while(in.hasNext() == true) { int firstVal = in.nextInt(); if (firstVal == -911) { break; } tempElement.setKeyValue(firstVal, 0); for(int i = 1; i<numKeyValues;i++) { tempElement.setKeyValue(in.nextInt(), i); } elementArray[placeValue] = tempElement; placeValue++; } // close while loop } // close method This part of the code was giving me a very nasty bug -- no matter how I finagled it, no matter what input I gave the program, it would always produce an array full of only a single value -- the last one. The problem, as I later determined it, was that because I had not created the tempElement variable within the loop, and because values were not being assigned to elementArray[] until after the loop had ended -- every term was defined rather as "tempElement" -- when the loop terminated, every slot in the array was filled with the last value tempElement had taken. I was able to fix this bug by moving the declaration of tempElement within the while loop. My question to you, Stackoverflow, is whether there is another (read: better) way to avoid this bug while keeping the variable declaration of tempElement outside the while loop. (suggestions for better title and tags also appreciated)

  • VEMap and a GeoRSS feed(hosted separately)

    - by Alexis Abril
    The scenario is as follows: A WCF web service exists that outputs a valid GeoRSS feed. This lives in its own domain as a number of different applications have access to it. A web page(on a different site) has been created with an instance of a VEMap(Bing/Virtual Earth map object). Now, VEMap can accept an input feed in this format via the following: var layer = new VEShapeLayer(); var veLayerSpec = new VEShapeSourceSpecification(VEDataType.GeoRSS, "someurl", layer); map.ImportShapeLayerData(veLayerSpec, onComplete, true); onComplete is a callback function I'm using to replace the default pin graphic with something custom. The question is in regards to "someurl", which is a path to a local xml file containing the geographic information(georss simple format). I've realized this feed and the map must be hosted in the same domain, so I've created a generic handler that reads the remote feed and returns it in the same format. var veLayerSpec = new VEShapeSourceSpecification(VEDataType.GeoRSS, "/somelocalhandler.ashx", layer); When I do this, I get the VEMap error("z is null"). This is the same error one would receive when trying to access a remote feed. When I copy the feed into a local xml file(ie, "feed.xml") there is no error. The order of operations is currently: remote feed - local handler - VEMap import If I'm over complicating this procedure, let me know! I'm a bit new to the Bing Maps API and might have missed something. Any assistance is appreciated.

  • LINQDataSource and private columns

    - by fyjham
    Hey, I was trying to use a ListView bound to a LinqDataSource to insert to a table where I had a few columns private to the table class (Specifically password columns - only access I want to give outside the class is methods that generate the salt and encrypt the password to store it in 1 go). I gave this a few shots, but I didn't come up with anything I really liked... was wondering if anyone has a better way to do this. The methods I've found: Use the LinqDataSource inserting event and make the appropriate calls on e.NewObject. I don't really like this because it's so far removed from the actual input and there's no simple way to hold the password in the meantime other than a class variable set during the ListView's inserting event (Which works, but seems a little dodgy). Open up these properties and just ask everyone to use the appropriate static methods for encoding the passwords they pass in. I don't really like this cause I'd prefer that class to enforce data integrity rather than relying on all calling code doing it properly... I'm currently going with option #1, but I don't really like passing values between events using class variables like that (It just seems unstructured... even though I can guarantee the events will happen in the right order). Does anyone know a better way, or alternatively am I being too pedantic and one of the methods above is actually the right way to go? Thanks

  • TextBox should display text in hexadecimal in a specific format

    - by Owais Wani
    I have a textbox in my xaml file which is editable. Now according to my project requirements content in textbox should only be 0-9 and a-f (hexadecimal values) and textbox should take the input based on hexadecimal values. Demonstratation: 12 ab 32 a5 64 Now if my cursor is at the end and i go on pressing backspace, it shud remove the values as it happens in a general text box. Now If my cursor is at the beginning of a5, and i press "delete key", the value should become like: 12 ab 32 56 4 If my cursor is at the end of a5 and i press the 'delete key" nothing should happen. I had done this successful in my C++ application as follows: void CMSP430CommPanel::textEditorTextChanged (TextEditor& editor) { if(&editor == m_texti2cWrite) { int count = 0; int location; String text1 = m_texti2cWrite->getText(); String text = m_texti2cWrite->getText().removeCharacters(" "); String hexString = String::empty; int countCaret = m_texti2cWrite->getCaretPosition(); for(int i=0; i < text.length(); i++) { hexString = hexString + String (&text[i], 1); if((i+1) % 2 == 0) { if(i != text.length()-1) { hexString = hexString + T(" "); count ++; } } count ++; } m_texti2cWrite->setText(hexString,false); if(text1.length() == m_texti2cWrite->getCaretPosition()) { m_texti2cWrite->setCaretPosition(count); } else { m_texti2cWrite->setCaretPosition(countCaret); } } } where m_texti2cWrite is the name given to textbox. How can i implement the same case in my wpf application which is MVVM based. I have a textbox which shud take inputs as I said above. please help!!!

  • Reasons for & against a Database

    - by dbemerlin
    Hi, i had a discussion with a coworker about the architecture of a program i'm writing and i'd like some more opinions. The Situation: The Program should update at near-realtime (+/- 1 Minute). It involves the movement of objects on a coordinate system. There are some events that occur at regular intervals (i.e. creation of the objects). Movements can change at any time through user input. My solution was: Build a server that runs continously and stores the data internally. The server dumps a state-of-the-program at regular intervals to protect against powerfailures and/or crashes. He argued that the program requires a Database and i should use cronjobs to update the data. I can store movement information by storing startpoint, endpoint and speed and update the position in the cronjob (and calculate collisions with other objects there) by calculating direction and speed. His reasons: Requires more CPU & Memory because it runs constantly. Powerfailures/Crashes might destroy data. Databases are faster. My reasons against this are mostly: Not very precise as events can only occur at full minutes (wouldn't be that bad though). Requires (possibly costly) transformation of data on every run from relational data to objects. RDBMS are a general solution for a specialized problem so a specialized solution should be more efficient. Powerfailures (or other crashes) can leave the Data in an undefined state with only partially updated data unless (possibly costly) precautions (like transactions) are taken. What are your opinions about that? Which arguments can you add for any side?

  • Key Tips in WPF

    - by Brad Leach
    Office 2007 and the Ribbon introduced the concept of "Key Tips". In short, every single command in the Ribbon receives a letter which you can press to activate that command. ... The letters are indicated by small "KeyTips" which indicate the letter to press to activate the control. KeyTips are displayed using the Alt key, so using them feels similar to how menu navigation works in Windows. (Source: http://blogs.msdn.com/jensenh/archive/2006/04/12/574930.aspx) An example of the Key Tips can be shown as follows. In this diagram, the use has pressed the ALT key, and is awaiting further input. Are there any WPF Open Source examples of "Key Tips"? How would you go about implementing something like this feature in a generic way (i.e. not requiring a Ribbon)? How would you implement this using a MVVM pattern (given that ICommand does not support InputBindings). Note: ActiPro have implemented this feature in their implementation of a Ribbon, but they have not released source code.

  • Best terminal environment for Cygwin/Windows?

    - by Anders Sandvig
    Today I run Cygwin with rxvt using the following startup line: rxvt -bg black -sl 8192 -fg white -sr -g 150x56 -fn "Fixedsys" -e /usr/bin/bash --login -i This gives me a resizeable native Windows window which is much better than the standard "DOS box" the default cygwin.bat provides. However, the current configuration does have a couple of issues: I am not able to enter non-ASCII characters into the terminal window (i.e. æ, ø, å and Æ, Ø, Å, which I use semi-frequently. In fact, the terminal will not even accept them when I paste them into the window. If I paste a string like "bølle" (Norwegian for "bulley"), all I get is "blle". I am not able to render UTF-8 character, they only show as ?, even if they are supported by the font (i.e. when rendering the same characters in ISO-8859-1 they show just fine.). I am running English Windows Vista with locale and keyboard layout set to Norwegian (ISO-8859-1 character set?), but I've had the exact same issue on Windows 2000 and XP. Anyone knows how to fix this (i.e. a better way to configure rxvt)? Apart from the issues mentioned above, I'm very happy with rxvt, so if I find a way to resolve them I'd like to continue using it. However, if the issues are not (easily) solvable, are the any other good terminal solutions for Cygwin? Update The solution provided by Andy and Mattias (editing the .inputrc file) did solve the input problem, but output rendering is still an issue. Output is fine when I render in ISO-8859-1, but when using UTF-8 I only get ? for non-ASCII characters. This behavior is consistent between rxvt, urxvt (under Cygwin XFree X Server), mintty and PuttyCyg. Is there a similar configuration file where output encoding can be set (i.e. the equivalent of setting output locale on a Linux system)?

  • Generic object to object mapping with parametrized constructor

    - by Rody van Sambeek
    I have a data access layer which returns an IDataRecord. I have a WCF service that serves DataContracts (dto's). These DataContracts are initiated by a parametrized constructor containing the IDataRecord as follows: [DataContract] public class DataContractItem { [DataMember] public int ID; [DataMember] public string Title; public DataContractItem(IDataRecord record) { this.ID = Convert.ToInt32(record["ID"]); this.Title = record["title"].ToString(); } } Unfortanately I can't change the DAL, so I'm obliged to work with the IDataRecord as input. But in generat this works very well. The mappings are pretty simple most of the time, sometimes they are a bit more complex, but no rocket science. However, now I'd like to be able to use generics to instantiate the different DataContracts to simplify the WCF service methods. I want to be able to do something like: public T DoSomething<T>(IDataRecord record) { ... return new T(record); } So I'd tried to following solutions: Use a generic typed interface with a constructor. doesn't work: ofcourse we can't define a constructor in an interface Use a static method to instantiate the DataContract and create a typed interface containing this static method. doesn't work: ofcourse we can't define a static method in an interface Use a generic typed interface containing the new() constraint doesn't work: new() constraint cannot contain a parameter (the IDataRecord) Using a factory object to perform the mapping based on the DataContract Type. does work, but: not very clean, because I now have a switch statement with all mappings in one file. I can't find a real clean solution for this. Can somebody shed a light on this for me? The project is too small for any complex mapping techniques and too large for a "switch-based" factory implementation.

  • ECM (Niche Vs Mass Market)

    - by Luj Reyes
    Hi Everyone, I recently started a little company with a couple of guys. Ours is the typical startup, a lot of ideas, dreams, talent and work hours :P. Our initial business plan was to develop a DM (Document Manager) with several features found on DropBox and other tools but with a big differentiator. Then we got in the team this Business Guy (I must say that several of us could be called 'Business Guys' but we are mainly hackers, he is just Another 'Networking Guy'), and along with him came this market analysis for a DM aimed at a very specific and narrow niche. We have many elements to believe in his market study and the idea is the classic "The market is X million, so if we grab a 10%...", and the market is really there to grab because all big providers deemed it too little and fled, let's say that the market is 5 million USD and demand very specific features. If we decide to go for this niche product we face a sales cycle of about 7 months, and the main goal of these revenue is to develop more ambitious projects. (Institutional VC is out of the question if you want to keep a marginal ownership of your company in my country). The only overlap between the niche and the mass market product features is the ability to store documents; everything else requires that we focus all of our efforts towards one or the other. I've studied a lot about the differences between Mass and Niche Markets, but I want to hear from people with actual experience. So everything comes down to this: If you have a really “saleable” idea what is the right thing to do: to go for the niche or go for the big prize and target primarily the mass market? Thanks for your input

  • Algorithm possible amounts (over)paid for a specific price, based on denominations

    - by Wrikken
    In a current project, people can order goods delivered to their door and choose 'pay on delivery' as a payment option. To make sure the delivery guy has enough change customers are asked to input the amount they will pay (e.g. delivery is 48,13, they will pay with 60,- (3*20,-)). Now, if it were up to me I'd make it a free field, but apparantly higher-ups have decided is should be a selection based on available denominations, without giving amounts that would result in a set of denominations which could be smaller. Example: denominations = [1,2,5,10,20,50] price = 78.12 possibilities: 79 (multitude of options), 80 (e.g. 4*20) 90 (e.g. 50+2*20) 100 (2*50) It's international, so the denominations could change, and the algorithm should be based on that list. The closest I have come which seems to work is this: for all denominations in reversed order (large=>small) add ceil(price/denomination) * denomination to possibles baseprice = floor(price/denomination) * denomination; for all smaller denominations as subdenomination in reversed order add baseprice + (ceil((price - baseprice) / subdenomination) * subdenomination) to possibles end for end for remove doubles sort Is seems to work, but this has emerged after wildly trying all kinds of compact algorithms, and I cannot defend why it works, which could lead to some edge-case / new countries getting wrong options, and it does generate some serious amounts of doubles. As this is probably not a new problem, and Google et al. could not provide me with an answer save for loads of pages calculating how to make exact change, I thought I'd ask SO: have you solved this problem before? Which algorithm? Any proof it will always work?

  • Preserving SCRIPT tags (and more) in CKEditor

    - by Jonathan Sampson
    Update: I'm thinking the solution to this problem is in CKEDITOR.config.protectedSource(), but my regular-expression experience is proving to be too juvenile to handle this issue. How would I go about exempting all tags that contain the 'preserved' class from being touched by CKEditor? Is it possible to create a block of code within the CKEditor that will not be touched by the editor itself, and will be maintained in its intended-state until explicitly changed by the user? I've been attempting to input javascript variables (bound in script tags) and a flash movie following, but CKEditor continues to rewrite my pasted code/markup, and in doing so breaking my code. I'm working with the following setup: <script type="text/javascript"> var editor = CKEDITOR.replace("content", { height : "500px", width : "680px", resize_maxWidth : "680px", resize_minWidth : "680px", toolbar : [ ['Source','-','Save','Preview'], ['Cut','Copy','Paste','PasteText','PasteFromWord','-','Print', 'SpellChecker', 'Scayt'], ['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'], ['Bold','Italic','Underline','Strike','-','Subscript','Superscript'], ['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'], ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'], ['Link','Unlink','Anchor'], ['Image','Table','HorizontalRule','SpecialChar'] ] }); CKFinder.SetupCKEditor( editor, "<?php print url::base(); ?>assets/ckfinder" ); </script> UPDATE: I suppose the most ideal solution would be to preserve the contents of any tag that contains class="preserve" enabling much more than the limited exclusives.

  • jQuery UI datepicker will not display - full code included

    - by Bill Brasky
    I am having trouble displaying the jQuery datepicker as shown here: http://jqueryui.com/demos/datepicker/ I believe I downloaded all of the proper files, but to be certain, I started from scratch and ripped the demo site. Not all of it, but what I believed to be the important parts. The result is no datepicker to be shown and no javascript errors. Here is my full code sample: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="stylesheet" href="http://static.jquery.com/ui/css/base2.css" type="text/css" media="all" /> <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/themes/base/jquery-ui.css" type="text/css" media="all" /> <link rel="stylesheet" href="http://static.jquery.com/ui/css/demo-docs-theme/ui.theme.css" type="text/css" media="all" /> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" charset="utf-8" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js"></script> <script type="text/javascript" charset="utf-8"> jQuery(function(){ jQuery("#datepicker").datepicker(); }); </script> </head> <body> <input type="text" id="datepicker" class="hasDatepicker" /> </body> </html> Any help would be very much appreciated. Thanks!
