• Eclipse autocompletion problem

  - by Gene Marin

  Just installed Eclipse Helios (Win7 64) and I'm having a strange problem. I type syso-Ctrl-Space which is expected to complete to System.out.println("") but it doesn't work! I searched the web for about an hour now, I set Preferences Java Editor Content Assist to defaults, nothing. Everything else seems to work. Ideas? To be clear: the shortcut works, it completes everything except "syso" as seen so far, on syso (also tried sysout) it says "No Default Proposals". I couldn't find this kind of shortcuts in the Content Assist, but I set them to default anyway.

• Zend_Form validation problem

  - by GrumpyCanuck

  I am having problems getting validation to work for a form built using Zend_Form. The idea is this: I have two dropdown. One is a list of players. The other is a list of free agents who play the same position as the player. I am using an onChange javascript callback to run some Ajax code that replaces the free agent list dropdown with a new one at the position of the player they've selected from the player dropdown. Now, perhaps this is the wrong way, but I built the form by creating an instance of Zend_Form and then creating all these setX methods that add elements to the form. My reasoning was that I wanted to display certain elements in specific places on the page, not just output $this-form on my template. The problem appears to be when I get the form post back, the validator seems to not know about the validation rule I set up for the free agent drop down. Here's some relevant code to look at. I'm a relative ZF n00b so feel free to tell me I am not doing things the ZF way if it leaps out at you. The action in the controller: public function indexAction() { if ($this->getRequest()->isPost()) { $form = new Baseball_Form_Transactions(); if ($form->isValid($this->_request->getPost())) { $data = $this->_request->getPost(); $leagueInfo = Doctrine::getTable('League')->findOneByShortName($data['shortLeagueName'])->toArray(); // Create the request top drop an existing player $transactionInfo = array( 'league_id' => $leagueInfo['id'], 'team_id' => $data['teamId'], 'player_id' => $data['players'], 'type' => 'drop', 'target_team_id' => 0, 'transaction_date' => date('Y-m-d H:m:s') ); $transaction = new Transaction(); $transaction->fromArray($transactionInfo); $transaction->save(); // Now we do the request to add a player $transactionInfo['team_id'] = 0; $transactionInfo['player_id'] = $data['freeAgents']; $transactionInfo['target_team_id'] = $data['teamId']; $transactionInfo['type'] = 'add'; $transaction = new Transaction(); $transaction->fromArray($transactionInfo); $transaction->save(); $this->_flashMessenger->addMessage('Added transaction'); } } $options = array( 'teamId' => $this->teamId, 'position' => 'C', 'leagueShortName' => $this->league ); $this->transactionForm->setMyPlayers($options); $this->transactionForm->setFreeAgents($options); $this->transactionForm->setTeamId($options); $this->transactionForm->setShortLeagueName($options); $this->view->transactionForm = $this->transactionForm; $this->view->messages = $this->_flashMessenger->getMessages(); $transaction = new Transaction(); $this->view->transactions = $transaction->byTeam($options); } Next we have the form itself public function setMyPlayers($options) { $data = Doctrine::getTable('Team')->find($options['teamId']); $players = array(); foreach ($data->Players->toArray() as $player) { $players[$player['id']] = "{$player['position']} - {$player['first_name']} {$player['last_name']}"; } $playersSelect = new Zend_Form_Element_Select( 'players', array( 'required' => true, 'label' => 'Players', 'multiOptions' => $players, ) ); $this->addElement($playersSelect); } public function setFreeAgents($options) { $q = Doctrine_Query::create() ->select('CONCAT(p.first_name, " ", p.last_name) as full_name, p.id, p.position') ->from('Player p') ->leftJoin('p.Teams t') ->leftJoin('t.League l ON l.short_name = ?', $options['leagueShortName']) ->where('t.id IS NULL') ->andWhere('p.position = ?', $options['position']) ->orderBy('p.last_name'); $q->setHydrationMode(Doctrine_Core::HYDRATE_ARRAY); $data = $q->execute(); $freeAgents = array(); foreach ($data as $player) { $freeAgents[$player['id']] = $player['full_name']; } $freeAgentsSelect = new Zend_Form_Element_Select( 'freeAgents', array( 'label' => 'Free Agents', 'multiOptions' => $freeAgents, 'size' => 15 ) ); $freeAgentsSelect->setRequired(true); $this->addElement($freeAgentsSelect); } public function setShortLeagueName($options) { $shortLeagueNameHidden = new Zend_Form_Element_Hidden( 'shortLeagueName', array('value' => $options['leagueShortName']) ); $this->addElement($shortLeagueNameHidden); } public function setTeamId($options) { $teamIdHidden = new Zend_Form_Element_Hidden( 'teamId', array('value' => $options['teamId']) ); $this->addElement($teamIdHidden); } There is no init or __construct() method in the form. My problem seems simple enough: reject the form contents as invalid if they have not selected someone from the free agent list. Right now, it sails through as valid. I've spent some considerable time searching online for an answer, and haven't been able to find it. Thanks in advance for any help.

• Problem searching a NSMutableArray

  Basically, I have a UISearchBar searching an NSMutableArray of stories that make up an RSS feed, and when you select a story, it loads in my app's UIWebView. It's difficult to explain, but I have a list of entries 1, 2, 3, and 4 and you search for '4'. 4 will be the first entry in the now-filtered list of data, right? You'd think that by selecting 4, it would load in the UIWebView. Well, the app seems to not recognize that you're selecting the first entry in a filtered list of data, and instead thinks that you're selecting the first entry in the unfiltered array of data, so it loads entry 1. Everything looks right in my code, but obviously it isn't. I know it's a confusing problem, but I hope I made it somewhat clear. Anyway, here's the relevant source so that you may see exactly what I mean: Search.h: http://www.scribd.com/doc/13107802/Searchh Search.m: http://www.scribd.com/doc/13107812/Searchm

I have to classify automaticaly those books into separated sets by topic, example : IT BOOKS : Java for dummies Javascript for dummies Learn flash in 30 days C++ programming HISTORY BOOKS : World wars America in 1960 Martin luther king's life BIOLOGY BOOKS : .... Do you guys know a classification algorithm/method to apply for that kind of problems ? A solution is to use an external API to define the category of the text, but the problem here is that books are in different languages : french, spanish, english ..

• Problem with writing if condition

  - by Himadri

  I have two decimal numbers. I want those number to be same upto 4 decimal points without rounding. If numbers are different I want 2nd number to be replaced by 1st. What if condition should I write? Eg, 1. num1 = 0.94618976 num2 = 0.94620239 If we round these numbers upto 4 decimal then we get 0.9462 same number, but I don't want to round these numbers. 2. num1 = 0.94620239 num2 = 0.94639125 The one way I found is take absolute difference of both numbers say diff and then check the value. My problem is of checking the range of diff. I am using delphi but you can answer in any language.Thank You.

• Efficient mass string search problem.

  - by Monomer

  The Problem: A large static list of strings is provided. A pattern string comprised of data and wildcard elements (* and ?). The idea is to return all the strings that match the pattern - simple enough. Current Solution: I'm currently using a linear approach of scanning the large list and globbing each entry against the pattern. My Question: Are there any suitable data structures that I can store the large list into such that the search's complexity is less than O(n)? Perhaps something akin to a suffix-trie? I've also considered using bi- and tri-grams in a hashtable, but the logic required in evaluating a match based on a merge of the list of words returned and the pattern is a nightmare, and I'm not convinced its the correct approach.

• Serialized form fields in Ruby on Rails problem

  - by Violet

  I'm having a problem making serialized columns in my model persist correctly in forms. If my model validation fails I want to redisplay the "new" page with all my model data still in the forms. Right now, everything except the serialized fields seem to persist (if my Order fails to purchase, on the "new" page the email is still filled in but the shipping address fields are not). Is this a Rails bug or am I doing something wrong? My model: class Order < ActiveRecord::Base serialize :shipping_address end My controller: def new @order = Order.new end def create @order = Order.new params[:order] if @order.purchase then render :action => "success" else render :action => "new" end end My view, new.html.haml: = form_for @order do |f| - if @order.errors.any? #errorExplanation %p The following errors occurred: %ul - for msg in @order.errors.full_messages %li= msg %h2 Billing Information = f.label :email = f.text_field :email %h2 Shipping Address = f.fields_for :shipping_address do |b| %p.field.address = b.label :address1 = b.text_field :address1 %p= f.submit "Place Order"

• Wordpress order/sort problem

  - by Spencer

  Hi, The Problem: I would like to sort my posts based on custom fields, when the user clicks on a link. I don't know if there is a parameter that can be passed via url to reorder posts. Comparison: I would like it to work similar to how you can sort songs in iTunes. The user simply clicks the "Artist" button and the songs are reorder alphabetically by artist's name. Example: The custom field could be the location where I was when I wrote the post. "Location = home" or "Location = office" etc. When the user click a links the page is reload with the posts reordered. Posts from home before ones from the office. Thanks for the help.

• Problem with HTML inside Javascript

  - by Vafello

  I am trying to implement 'time-ago' feature in my website using a JQuery timeago plugin. Unfortunately I have encountered some problems. <script type="text/javascript" charset="utf-8"> jQuery("abbr.timeago").timeago(); </script> var content = document.getElementById('div'); var html = "<abbr class=timeago title=2008-07-17T09:24:17Z></abbr>" + '<br><br>'; content.innerHTML += html <div id='div'></div This jquery plugin basically convert timestamp from the title and print it in a nice format for every abbr class=timeago. The problem is that the code above doesn't work, but if I put it within this div it works fine. I think it is maybe because this jquery plugin is applied before generating html by javascript, but I am not sure. Any ideas?

I searched the internet and found out, that adding this can help. <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" /> <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" /> This solved the issue for some people but it didnt help me.

• makefile compilation problem

  - by mistique

  He I have a problem with a makefile. I have three classes. They do pretty simple stuff. One does an addition on a subtraction, and the last one will instantiate the two and simply print the resulted addition and subtraction. Now when I create my makefile, I compile my Plus.java and my Minus.java but don't know how to compile the main class because it depends on the previous two. I want to compile and run it from the makefile if it's possible. I get the above results when I try to run make: javac -g Plus.class Minus.class javac: invalid flag: Plus.class Usage: javac use -help for a list of possible options make: * [Operation.class] Error 2 I don't know how to procede, please forgive me if my question is to simple but I am new working with these stuff. I've searched many sites but with no answer.

• Problem Paging with Post Action in ASP.NET MVC

  - by Lukasz

  I have a page that takes a number of parameters on a form and posts them to an action. It returns a number of search results that need to be paged through. My pager uses ActionLink; <%= Html.ActionLink(i.ToString(), "Basic", new { page = (i - 1) })%> The results comeback as expected but when I click on page two it goes to the default Action, not the one marked with post. The form values do no get submitted again and the results that are shown for page two are the default results not filters with the parameters. I am not sure how to solve this problem? One way was to save the form values into the database on the post and reading them back on the default action but it seems overkill. Thank You!

• DB2 ZOS String Comparison Problem

  - by John

  I am comparing some CHAR data in a where clause in my sql like this, where PRI_CODE < PriCode The problem I am having is when the CHAR values are of different lengths. So if PRI_CODE = '0800' and PriCode = '20' it is returning true instead of false. It looks like it is comparing it like this '08' < '20' instead of like '0800' < '20' Does a CHAR comparison start from the Left until one or the other values end? If so how do I fix this? My values can have letters in it so convering to numeric is not an option.

• Nesting Patterns Algorithms / Cutting Waste Problem

  - by WedTM

  First off, I'd like to say that I'm already looking into the "Cutting Stock Problem" algorithm, however I feel that I need a bit more clarification, and possibly some help with some of the math (Not my strong point). What I need to do is have an offset pattern that causes the circle to fit in the crevasse created by having the two circular dies sitting next to each other on the previous line, like so: O O O O O O O O O O O O O O O O O I'm hoping someone can point me towards the right algorithm for this! Thanks!

• z-index problem in IE6

  - by simonkagwe

  I have been struggling with a z-index problem in IE6 for quite some time now. I require part of the 'header' portion in my website to open up (using jQuery), and cover a portion of the 'content' section which comes after it. The thing works like a charm on all the browsers I've tested it on (Firefox, Chrome, Opera), but IE6 instead pushes down the content section, which is not what I want. The website itself is here I have done extensive research both here on SO and thro Google but all the workarounds I've found don't work for my case. Please help.

• Python beginner, strange output problem

  - by Protean

  I'm having a weird problem with the following piece of code. from math import sqrt def Permute(array): result1 = [] result2 = [] if len(array) <= 1: return array for subarray in Permute(array[1:]): for i in range(len(array)): temp1 = subarray[:i]+array[0]+subarray[i:] temp2 = [0] for num in range(len(array)-1): temp2[0] += (sqrt(pow((temp1[num+1][1][0]-temp1[num][1][0]),2) + pow((temp1[num+1][1][1]-temp1[num][1][1]),2))) result1.append(temp1+temp2) return result1 a = [['A',[50,1]]] b = [['B',[1,1]]] c = [['C',[100,1]]] array = [a,b,c] result1 = Permute(array) for i in range(len(result1)): print (result1[i]) print (len(result1)) What it does is find all the permutations of the points abc and then returns them along with the sum of the distances between each ordered point. It does this; however, it also seems to report a strange additional value, 99. I figure that the 99 is coming from the computation of the distance between point a and c but I don't understand why it is appearing in the final output as it does.

• table cell background color change problem

  - by Mellon

  I work on another guy's code, and I try to change the table cell background color when mouse over the cell, and change back to the original background color when mouse leave. I use the following code: var bgcolor=$(".cell-el").css("background-color") $(".cell-el").hover( function(){ $(this).css("background-color", "#3c3c36")}, //mouse enter, bg-color change function(){ $(this).css("background-color", bgcolor) // mouse leave, bg-color change back }) Things are working fine, EXCEPT that when mouse first time enter the cell, the cell background color is not changed to "#3c3c36", but when mouse leave the cell after first entering and enter in the cell again, the cell's background color changed to "#3c3c36". That's the cell color never change for mouse first enter, after that, everything is working great. What's could be the cause of this problem?

• Problem in displaying custom UITableViewCell

  - by Vin

  Hi All, I have a tableview displaying data using a custom UITableViewCell(say cell1). On touch of a row, I change the custom cell to another custom UITableViewCell(say cell2). Also I increase the size of row of the selected cell to accomodate, more items of cell2. My problem is that the approach works fine when the number of rows in table view is less. When the number of rows increses, the rows expand on touching, but the data displayed is same as that of cell1. Cell2 doesn't seem to be loaded at all. Looking forward for a reply soon....Thanks in advance.

• Stringbuilder problem creating dynamic links

  Hi all, I'm having an issue creating a link like "<a href="javascript:window.open('www.microsoft.com');">Visit Microsoft</a> using stringbuilder. I am adding html to a panel dynamically and I am trying to create a popup link. The problem is that for some reason the link gets "mixed up".

• .NET Remoting Client's Problem when running on the machine with Multi NICs

  I built a .NET Remoting Client which works quite fine on the machine of single NIC, and lots of testing messages received via remoting event. But when additional NIC was added, the Client seemed to be able to connect the remoting Server, but the testing messages cannot arrive anymore. From debugging, the server end did trigger the event but the client didn't get that. Checking from google and find that a similar problem report: http://www.eggheadcafe.com/community/aspnet/2/10061570/reply.aspx I just wonder if any solutions? Thanks in advance!
