• What is the best way to slide a panel in WPF?

  - by Kris Erickson

  I have a fairly simple UserControl that I have made (pardon my Xaml I am just learning WPF) and I want to slide the off the screen. To do so I am animating a translate transform (I also tried making the Panel the child of a canvas and animating the X position with the same results), but the panel moves very jerkily, even on a fairly fast new computer. What is the best way to slide in and out (preferably with KeySplines so that it moves with inertia) without getting the jerkyness. I only have 8 buttons on the panel, so I didn't think it would be too much of a problem. Here is the Xaml I am using, it runs fine in Kaxaml, but it is very jerky and slow (as well as being jerkly and slow when run compiled in a WPF app). <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="1002" Height="578"> <UserControl.Resources> <Style TargetType="Button"> <Setter Property="Control.Padding" Value="4"/> <Setter Property="Control.Margin" Value="10"/> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Grid Name="backgroundGrid" Width="210" Height="210" Background="#00FFFFFF"> <Grid.BitmapEffect> <BitmapEffectGroup> <DropShadowBitmapEffect x:Name="buttonDropShadow" ShadowDepth="2"/> <OuterGlowBitmapEffect x:Name="buttonGlow" GlowColor="#A0FEDF00" GlowSize="0"/> </BitmapEffectGroup> </Grid.BitmapEffect> <Border x:Name="background" Margin="1,1,1,1" CornerRadius="15"> <Border.Background> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="#FF0062B6"/> <GradientStop Offset="1" Color="#FF0089FE"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.Background> </Border> <Border Margin="1,1,1,0" BorderBrush="#FF000000" BorderThickness="1.5" CornerRadius="15"/> <ContentPresenter HorizontalAlignment="Center" Margin="{TemplateBinding Control.Padding}" VerticalAlignment="Center" Content="{TemplateBinding ContentControl.Content}" ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <Canvas> <Grid x:Name="Panel1" Height="578" Canvas.Left="0" Canvas.Top="0"> <Grid.RenderTransform> <TransformGroup> <TranslateTransform x:Name="panelTranslate" X="0" Y="0"/> </TransformGroup> </Grid.RenderTransform> <Grid.RowDefinitions> <RowDefinition Height="287"/> <RowDefinition Height="287"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition x:Name="Panel1Col1"/> <ColumnDefinition x:Name="Panel1Col2"/> <ColumnDefinition x:Name="Panel1Col3"/> <ColumnDefinition x:Name="Panel1Col4"/> <!-- Set width to 0 to hide a column--> </Grid.ColumnDefinitions> <Button x:Name="Panel1Product1" Grid.Column="0" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center"> <Button.Triggers> <EventTrigger RoutedEvent="Button.Click" SourceName="Panel1Product1"> <EventTrigger.Actions> <BeginStoryboard> <Storyboard> <DoubleAnimation BeginTime="00:00:00.6" Duration="0:0:3" From="0" Storyboard.TargetName="panelTranslate" Storyboard.TargetProperty="X" To="-1000"/> </Storyboard> </BeginStoryboard> </EventTrigger.Actions> </EventTrigger> </Button.Triggers> </Button> <Button x:Name="Panel1Product2" Grid.Column="0" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product3" Grid.Column="1" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product4" Grid.Column="1" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product5" Grid.Column="2" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product6" Grid.Column="2" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product7" Grid.Column="3" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product8" Grid.Column="3" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/> </Grid> </Canvas> </UserControl>

• starting with flex - please let me know if the direction is right (ActionScript vs MXML separation)

  - by Piotr

  Hi, I've just started learning flex using OReilly "Programming Flex 3.0". After completing three chapters and starting fourth (ActionScript), and not having enough patience to wait till completing chapter 22 I started to practice :) One bit that I have most worries about right now is the the dual coding mode (MXML vs ActionScript) Please have a look at my code below (it compiles via mxmlc design.mxml, second file 'code.as' should be in same directory) and advise if the separation I used between visual design and code is appropriate. Also - if some smart guy could show me how to recode same example with *.as being a class file [package?] it would be highly appreciated. I got lost with creating directory structure for package - and did not find it most intuitive, especially for small project that has two files like my example.

If you have comments that this calculator does not calculate properly, they are also appreciated, yet most important are comments on best practices in Flex.

• how to get 12 for joel test working in a small team of 3-4 on php website?

  - by keisimone

  Hi i read this inspired, i am asking for specific help to achieve a 12 for my current project. i am working in a team of 3-4 on a php project that is based on cakephp. i only have a dedicated server running on linux which i intend to have the website live on. and i have a plan with assembla where i am using its svn repository. that's it. i like to hear a major, impactful step towards answering each point raised by the joel test. by impactful i mean doing just this one thing would raise my project to scoring or close to scoring on that area of the joel test. lets begin: 1) do you have a source control system? I am very proud to say learning how to use svn even though we know nuts about branch/release policies made the biggest impact to our programming lives. and the svn repos is on assembla paid plan. Feel free to add if anyone thinks we can do more in this area. 2) Can you make a build in one step? i think the issue is how do i define as a build? i think we are going to define it as if tomorrow my dedicated server crashed and we found another server from another normal hosting provider and all my team's machines all destroyed, how are we going to get the website up again? my code is in svn on assembla. 1 step means as close to 1 button to push as possible. 3)Do you make daily builds? i know nothing about this. please help. i googled and came across this phpundercontrol. but i am not sure if we can get that to work with assembla. are there easier ways? 4)Do you have a bug database? we have not used the assembla features on bug tracking. ashamed to say. i think i will sort this out myself. 5)Do you fix bugs before writing new code? policy issue. i will sort it out myself. 6)Do you have an up-to-date schedule? Working on it. Same as above. estimates have historically been overly optimistic. having spent too much time using all sorts of funny project management tools, i think this time i am going to use just paper and pen. please dont tell me scrum. i need to keep things even simpler than that. 7)Do you have a spec? We do, but its in paper and pen. what would be a good template? 8)Do programmers have quiet working conditions? Well we work at home and in distributed manner. so .. 9)Do you use the best tools money can buy? We use cheap tools. we are not big. 10)Do you have testers? NO testers. Since we have a team of 3, i think i should go get 1 tester. even on a part time basis. so i should get this 1 part time tester test in what manner to extract maximum effects? should i get him to write out the test scenarios and expected outcomes and then test it? or i write the test scenarios and then ask him to do it? we will be writing the test cases ourselves using simpletest. i came across selenium. how useful is that? 11)Do new candidates write code during their interview? Not applicable. But i will do it next time i try to hire anyone else. hires or contractors alike. 12)Do you do hallway usability testing? Will do so on a per month or per milestone basis. i will grab my friends who are not net-savvy. they will be the best testers of this type. Thank you.

• How do I change variables from different classes?

  - by Dan T

  Before I delve into it, I'm very new to Android and I have just started learning Java last month. I've hit bumps while trying to develop my first simple app. Most of these hurdles were jumped thanks to random tutorials online. MY CODE IS VERY MESSY. Any tips are appreciated. The question above is quite broad, but this is what I want to do: It's a essentially a blood alcohol content calculator / drink keeper-tracker. Basic layout: http://i.imgur.com/JGuh7.jpg The buttons along the bottom are just regular buttons, not ImageButtons (had problems with that) Here's some example code of one: <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_marginRight="5dp" android:background="@drawable/addbeer"/> The buttons and TextView are all in main.xml. I have variables defined in a class called Global.java: package com.dantoth.drinkingbuddy; import android.app.Activity; public class Global extends Activity{ public static double StandardDrinks = 0; public static double BeerOunces = 12; public static double BeerPercentAlcohol = .05; public static double BeerDrink = BeerOunces * BeerPercentAlcohol; public static double BeerDrinkFinal = BeerDrink * 1.6666666; public static double ShotOunces = 1.5; public static double ShotPercentAlcohol = .4; public static double ShotDrink = ShotOunces * ShotPercentAlcohol; public static double ShotDrinkFinal = ShotDrink * 1.6666666; public static double WineOunces = 5; public static double WinePercentAlcohol = .12; public static double WineDrink = WineOunces * WinePercentAlcohol; public static double WineDrinkFinal = WineDrink * 1.6666666; public static double OtherOunces; public static double OtherPercentAlcohol; public static double OtherDrink = OtherOunces * (OtherPercentAlcohol * .01); public static double OtherDrinkFinal = OtherDrink * 1.6666666; public static double GenderConstant = 7.5; //9 for female public static double Weight = 180; public static double TimeDrinking = 60; public static double Hours = TimeDrinking / 60; public static double Bac = ((StandardDrinks / 2) * (GenderConstant / Weight)) - (0.017 * Hours); } The last variable is the important part. It calculates your BAC based on the factors involved. When I press the add beer button (Button01) I make it add 1 to StandardDrinks, simulating drinking one beer. The other variables in the Bac formula have values assigned to them in Global.java. The code that makes the beer button do stuff is in my regular class, drinkingbuddy.java: public class DrinkingBuddy extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button button = (Button) findViewById(R.id.Button01); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Global.StandardDrinks = Global.StandardDrinks + Global.BeerDrinkFinal; Toast.makeText(DrinkingBuddy.this, "Mmmm... Beer", Toast.LENGTH_SHORT).show(); } }); By my perception, StandardDrinks should now have a value of 1. However, when I click the Calculate BAC button (Button05) it merely outputs the variable Bac as if StandardDrinks was still set to 0. Here is the code for the Calculate BAC button (Button05): Button button4 = (Button) findViewById(R.id.Button05); button4.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { TextView texty; texty = (TextView) findViewById(R.id.texty1); texty.setText("Your BAC is " + Global.Bac ); } }); It outputs the following to the text view: "Your BAC is -0.017". This is the Bac value for if StandardDrinks was still 0, so obviously there is some problem communicating between the classes. Can anyone help me?? The other elements of the formula (weight, time spent drinking, and the alcohol %'s and such) are variables because I will ultimately allow the user to change those values in the settings. I've heard around the water cooler that global variables are not good programming style, but this is the closest I've come to getting it to work. Any other ways of doing it are very much welcomed!

• Creating a menu using xslt for Umbraco

  - by rob_g

  I've created a menu in umbraco using XSLT. The menu is using the usual ul and li elements and I'm displaying only the first level of the menu. The aim is to create a menu that expands to show the sub menu when I click a parent node (in the top level). I am after the xslt I would need to expose the sub menu when clicked. I think I would need to make use of ancestor-or-self to detect the current menu and parent menu and display them and also the $currentPage variable. I have the following xslt: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxml="urn:schemas-microsoft-com:xslt" xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" xmlns:tagsLib="urn:tagsLib" xmlns:urlLib="urn:urlLib" exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets tagsLib urlLib "> <xsl:output method="xml" omit-xml-declaration="yes"/> <xsl:param name="currentPage"/> <xsl:template match="/"> <div id="kb-categories"> <h3>Categories</h3> <xsl:call-template name="drawNodes"> <xsl:with-param name="parent" select="$currentPage/ancestor-or-self::node [@level=1]"/> </xsl:call-template> </div> </xsl:template> <xsl:template name="drawNodes"> <xsl:param name="parent"/> <xsl:if test="(umbraco.library:IsProtected($parent/@id, $parent/@path) = 0 or (umbraco.library:IsProtected($parent/@id, $parent/@path) = 1)) and $parent/@level = 1"> <ul class="kb-menuLevel1" > <xsl:for-each select="$parent/node [string(./data [@alias='showInMenu']) = 1]"> <li> <a href="/kb{umbraco.library:NiceUrl(@id)}"> <xsl:value-of select="@nodeName"/> </a> <xsl:variable name="level" select="@level" /> <xsl:if test="(count(./node [string(./data [@alias='showInMenu']) = '1']) &gt; 0)"> <xsl:call-template name="drawNodes"> <xsl:with-param name="parent" select="."/> </xsl:call-template> </xsl:if> </li> </xsl:for-each> </ul> </xsl:if> <xsl:if test="(umbraco.library:IsProtected($parent/@id, $parent/@path) = 0 or (umbraco.library:IsProtected($parent/@id, $parent/@path) = 1)) and $parent/@level &gt; 1"> <ul class="kb-menuLevel{@level}" style="display: none;"> <xsl:for-each select="$parent/node [string(./data [@alias='showInMenu']) = 1]"> <li> <a href="/kb{umbraco.library:NiceUrl(@id)}"> <xsl:value-of select="@nodeName"/> </a> <xsl:variable name="level" select="@level" /> <xsl:if test="(count(./node [string(./data [@alias='showInMenu']) = '1']) &gt; 0)"> <xsl:call-template name="drawNodes"> <xsl:with-param name="parent" select="."/> </xsl:call-template> </xsl:if> </li> </xsl:for-each> </ul> </xsl:if> </xsl:template> </xsl:stylesheet> I suspect this could be improved using apply-templates, but I'm not yet up to speed with that (this being only the second day of my learning xslt). My menu: Item 1 Item 2 Item 3 Item 4 when I click on Item 2 I want to see it's child menu too: Item 1 Item 2 -- Item 2.1 -- Item 2.2 Item 3 Item 4 and so on down the nested menu.

• Am I crazy? (How) should I create a jQuery content editor?

  - by Brendon Muir

  Ok, so I created a CMS mainly aimed at Primary Schools. It's getting fairly popular in New Zealand but the one thing I hate with a passion is the largely bad quality of in browser WYSIWYG editors. I've been using KTML (made by InterAKT which was purchased by Adobe a few years ago). In my opinion this editor does a lot of great things (image editing/management, thumbnailing and pretty good content editing). Unfortunately time has had its nasty way with this product and new browsers are beginning to break features and generally degrade the performance of this tool. It's also quite scary basing my livelihood on a defunct product! I've been hunting, in fact I regularly hunt around to see if anything has changed in the WYSIWYG arena. The closest thing I've seen that excites me is the WYSIHAT framework, but they've decided to ignore a pretty relevant editing paradigm which I'm going to outline below. This is the idea for my proposed editor, and I don't know of any existing products that can do this properly: Right, so the traditional model for editing let's say a Page in a CMS is to log into a 'back end' and click edit on the page. This will then load another screen with the editor in it and perhaps a few other fields. More advanced CMS's will maybe have several editing boxes that are for different portions of the page. Anyway, the big problem with this way of doing things is that the user is editing a document outside of the final context it will appear in. In the simplest terms, this means the page template. Many things can be wrong, e.g. the with of the editing area might be different to the width of the actual template area. The height is nearly always fixed because existing editors always seem to use IFRAMES for backward compatibility. And there are plenty of other beefs which I'm sure you're quite aware of if you're in this development area. Here's my editor utopia: You click 'Edit Page': The actual page (with its actual template) displays. Portions of the page have been marked as editable via a class name. You click on one of these areas (in my case it'd just be the big 'body' area in the middle of the template) and a editing bar drops down from the top of the screen with all your standard controls (bold, italic, insert image etc...). Iframes are never used, instead we rely on setting contentEditable to true on the DIV's in question. Firefox 2 and IE6 can go away, let's move on. You can edit the page knowing exactly how it will look when you save it. Because all the styles for this template are loaded, your headings will look correct, everything will be just dandy. Is this such a radical concept? Why are we still content with TinyMCE and that other editor that is too embarrassing to use because it sounds like a swear word!? Let's face the facts: I'm a JavaScript novice. I did once play around in this area using the Javascript Anthology from SitePoint as a guide. It was quite a cool learning experience, but they of course used the IFRAME to make their lives easier. I tried to go a different route and just use contentEditable and even tried to sidestep the native content editing routines (execCommand) and instead wrote my own. They kind of worked but there were always issues. Now we have jQuery, and a few libraries that abstract things like IE's lack of Range support. I'm wondering, am I crazy, or is it actually a good idea to try and build an editor around this editing paradigm using jQuery and relevant plugins to make the job easier? My actual questions: Where would you start? What plugins do you know of that would help the most? Is it worth it, or is there a magical project that already exists that I should join in on? What are the biggest hurdles to overcome in a project like this? Am I crazy? I hope this question has been posted on the right board. I figured it is a technical question as I'm wanting to know specific hurdles and pitfalls to watch out for and also if it is technically feasible with todays technology. Looking forward to hearing peoples thoughts and opinions.

• Job conditions conflicting with personal principles on software-development - how much is too much?

  - by Baelnorn

  Sorry for the incoming wall'o'text (and for my probably bad English) but I just need to get this off somehow. I also accept that this question will be probably closed as subjective and argumentative, but I need to know one thing: "how much BS are programmers supposed to put up with before breaking?" My background I'm 27 years old and have a B.Sc. in Computer engineering with a graduation grade of 1.8 from a university of applied science. I went looking for a job right after graduation. I got three offers right away, with two offers paying vastly more than the last one, but that last one seemed more interesting so I went for that. My situation I've been working for the company now for 17 months now, but it feels like a drag more and more each day. Primarily because the company (which has only 5 other developers but me, and of these I work with 4) turned out to be pretty much the anti-thesis of what I expected (and was taught in university) from a modern software company. I agreed to accept less than half of the usual payment appropriate for my qualification for the first year because I was promised a trainee program. However, the trainee program turned out to be "here you got a computer, there's some links on the stuff we use, and now do what you colleagues tell you". Further, during my whole time there (trainee or not) I haven't been given the grace of even a single code-review - apparently nobody's interested in my work as long as it "just works". I was told in the job interview that "Microsoft technology played a central role in the company" yet I've been slowly eroding my congnitive functions with Flex/Actionscript/Cairngorm ever since I started (despite having applied as a C#/.NET developer). Actually, the company's primary projects are based on Java/XSLT and Flex/Actionscript (with some SAP/ABAP stuff here and there but I'm not involved in that) and they've been working on these before I even applied. Having had no experience either with that particular technology nor the framework nor the field (RIA) nor in developing business scale applications I obviously made several mistakes. However, my boss told me that he let me make those mistakes (which ate at least 2 months of development time on their own) on purpose to provide some "learning experience". Even when I was still a trainee I was already tasked with working on a business-critical application. On my own. Without supervision. Without code-reviews. My boss thinks agile methods are a waste of time/money and deems putting more than one developer on any project not efficient. Documentation is not necessary and each developer should only document what he himself needs for his work. Recently he wanted us to do bug tracking with Excel and Email instead of using an already existing Bugzilla, overriding an unanimous decision made by all developers and testers involved in the process - only after another senior developer had another hour-long private discussion with him he agreed to let us use the bugtracker. Project management is basically not present, there are only a few Excel sheets floating around where the senior developer lists some things (not all, mind you) with a time estimate ranging from days to months, trying to at least somehow organize the whole mess. A development process is also basically not present, each developer just works on his own however he wants. There are not even coding conventions in the company. Testing is done manually with a single tester (sometimes two testers) per project because automated testing wasn't given the least thought when the whole project was started. I guess it's not a big surprise when I say that each developer also has his own share of hundreds of overhours (which are, of course, unpaid). Each developer is tasked with working on his own project(s) which in turn leads to a very extensive knowledge monopolization - if one developer was to have an accident or become ill there would be absolutely no one who could even hope to do his work. Considering that each developer has his own business-critical application to work on, I guess that's a pretty bad situation. I've been trying to change things for the better. I tried to introduce a development process, but my first attempt was pretty much shot down by my boss with "I don't want to discuss agile methods". After that I put together a process that at least resembled how most of the developers were already working and then include stuff like automated (or at least organized) testing, coding conventions, etc. However, this was also shot down because it wasn't "simple" enought to be shown on a business slide (actually, I wasn't even given the 15 minutes I'd have needed to present the process in the meeting). My problem I can't stand working there any longer. Seriously, I consider to resign on monday, which still leaves me with 3 months to work there due to the cancelation period. My primary goal since I started studying computer science was being a good computer scientist, working with modern technologies and adhering to modern and proven principles and methods. However, the company I'm working for seems to make that impossible. Some days I feel as if was living in a perverted real-life version of the Dilbert comics. My question Am I overreacting? Is this the reality each graduate from university has to face? Should I betray my sound principles and just accept these working conditions? Or should I gtfo of there? What's the opinion of other developers on this matter. Would you put up with all that stuff?

• Implementation question involving implementing an interface

  - by Vivin Paliath

  I'm writing a set of collection classes for different types of Trees. I'm doing this as a learning exercise and I'm also hoping it turns out to be something useful. I really want to do this the right way and so I've been reading Effective Java and I've also been looking at the way Joshua Bloch implemented the collection classes by looking at the source. I seem to have a fair idea of what is being done, but I still have a few things to sort out. I have a Node<T> interface and an AbstractNode<T> class that implements the Node interface. I then created a GenericNode<T> (a node that can have 0 to n children, and that is part of an n-ary tree) class that extends AbstractNode<T> and implements Node<T>. This part was easy. Next, I created a Tree<T> interface and an AbstractTree<T> class that implements the Tree<T> interface. After that, I started writing a GenericTree<T> class that extends AbstractTree<T> and implements Tree<T>. This is where I started having problems. As far as the design is concerned, a GenericTree<T> can only consist of nodes of type GenericTreeNode<T>. This includes the root. In my Tree<T> interface I have: public interface Tree<T> { void setRoot(Node<T> root); Node<T> getRoot(); List<Node<T>> postOrder(); ... rest omitted ... } And, AbstractTree<T> implements this interface: public abstract class AbstractTree<T> implements Tree<T> { protected Node<T> root; protected AbstractTree() { } protected AbstractTree(Node<T> root) { this.root = root; } public void setRoot(Node<T> root) { this.root = root; } public Node<T> getRoot() { return this.root; } ... rest omitted ... } In GenericTree<T>, I can have: public GenericTree(Node<T> root) { super(root); } But what this means is that you can create a generic tree using any subtype of Node<T>. You can also set the root of a tree to any subtype of Node<T>. I want to be able to restrict the type of the node to the type of the tree that it can represent. To fix this, I can do this: public GenericTree(GenericNode<T> root) { super(root); } However, setRoot still accepts a parameter of type Node<T>. Which means a user can still create a tree with the wrong type of root node. How do I enforce this constraint? The only way I can think of doing is either: Do an instanceof which limits the check to runtime. I'm not a huge fan of this. Remove setRoot from the interface and have the base class implement this method. This means that it is not part of the contract and anyone who wants to make a new type of tree needs to remember to implement this method. Is there a better way? The second question I have concerns the return type of postOrder which is List<Node<T>>. This means that if a user is operating on a GenericTree<T> object and calls postOrder, he or she receives a list that consists of Node<T> objects. This means when iterating through (using a foreach construct) they would have perform an explicit cast to GenericNode<T> if they want to use methods that are only defined in that class. I don't like having to place this burden on the user. What are my options in this case? I can only think of removing the method from the interface and have the subclass implement this method making sure that it returns a list of appropriate subtype of Node<T>. However, this once again removes it from the contract and it's anyone who wants to create a new type of tree has to remember to implement this method. Is there a better way?

• Neural Network Always Produces Same/Similar Outputs for Any Input

  - by l33tnerd

  I have a problem where I am trying to create a neural network for Tic-Tac-Toe. However, for some reason, training the neural network causes it to produce nearly the same output for any given input. I did take a look at Artificial neural networks benchmark, but my network implementation is built for neurons with the same activation function for each neuron, i.e. no constant neurons. To make sure the problem wasn't just due to my choice of training set (1218 board states and moves generated by a genetic algorithm), I tried to train the network to reproduce XOR. The logistic activation function was used. Instead of using the derivative, I multiplied the error by output*(1-output) as some sources suggested that this was equivalent to using the derivative. I can put the Haskell source on HPaste, but it's a little embarrassing to look at. The network has 3 layers: the first layer has 2 inputs and 4 outputs, the second has 4 inputs and 1 output, and the third has 1 output. Increasing to 4 neurons in the second layer didn't help, and neither did increasing to 8 outputs in the first layer. I then calculated errors, network output, bias updates, and the weight updates by hand based on http://hebb.mit.edu/courses/9.641/2002/lectures/lecture04.pdf to make sure there wasn't an error in those parts of the code (there wasn't, but I will probably do it again just to make sure). Because I am using batch training, I did not multiply by x in equation (4) there. I am adding the weight change, though http://www.faqs.org/faqs/ai-faq/neural-nets/part2/section-2.html suggests to subtract it instead. The problem persisted, even in this simplified network. For example, these are the results after 500 epochs of batch training and of incremental training. Input |Target|Output (Batch) |Output(Incremental) [1.0,1.0]|[0.0] |[0.5003781562785173]|[0.5009731800870864] [1.0,0.0]|[1.0] |[0.5003740346965251]|[0.5006347214672715] [0.0,1.0]|[1.0] |[0.5003734471544522]|[0.500589332376345] [0.0,0.0]|[0.0] |[0.5003674110937019]|[0.500095157458231] Subtracting instead of adding produces the same problem, except everything is 0.99 something instead of 0.50 something. 5000 epochs produces the same result, except the batch-trained network returns exactly 0.5 for each case. (Heck, even 10,000 epochs didn't work for batch training.) Is there anything in general that could produce this behavior? Also, I looked at the intermediate errors for incremental training, and the although the inputs of the hidden/input layers varied, the error for the output neuron was always +/-0.12. For batch training, the errors were increasing, but extremely slowly and the errors were all extremely small (x10^-7). Different initial random weights and biases made no difference, either. Note that this is a school project, so hints/guides would be more helpful. Although reinventing the wheel and making my own network (in a language I don't know well!) was a horrible idea, I felt it would be more appropriate for a school project (so I know what's going on...in theory, at least. There doesn't seem to be a computer science teacher at my school). EDIT: Two layers, an input layer of 2 inputs to 8 outputs, and an output layer of 8 inputs to 1 output, produces much the same results: 0.5+/-0.2 (or so) for each training case. I'm also playing around with pyBrain, seeing if any network structure there will work. Edit 2: I am using a learning rate of 0.1. Sorry for forgetting about that. Edit 3: Pybrain's "trainUntilConvergence" doesn't get me a fully trained network, either, but 20000 epochs does, with 16 neurons in the hidden layer. 10000 epochs and 4 neurons, not so much, but close. So, in Haskell, with the input layer having 2 inputs & 2 outputs, hidden layer with 2 inputs and 8 outputs, and output layer with 8 inputs and 1 output...I get the same problem with 10000 epochs. And with 20000 epochs. Edit 4: I ran the network by hand again based on the MIT PDF above, and the values match, so the code should be correct unless I am misunderstanding those equations. Some of my source code is at http://hpaste.org/42453/neural_network__not_working; I'm working on cleaning my code somewhat and putting it in a Github (rather than a private Bitbucket) repository. All of the relevant source code is now at https://github.com/l33tnerd/hsann.

  Hi all , I urgently need your help . I am new to consuming a web service using SOAP protocol. I have been given a demo webservice URL which ends in .WSDL and NOT .asml?WSDL. The problem is I cannot add a web reference using Visual studio OR Disco.exe or Wsdl.exe - This webservice has been created on a java platform and for security reasons the only way to make a invoke the webservice is at runtime using SOAP protocol IN asp.net (VB). I I have created some code but cannot seem to send the soap object to the receiving web service. If I could get a solution with step by step instructions on how I can send a SOAP REQUEST.

• Hard to append a table with many records into another without generating duplicates

  - by Bill Mudry

  I may seem to be a bit wordy at first but for the hope it will be easier for all of you to understand what I am doing in the first place. I have an uncommon but enjoyable activity of collecting as many species of wood from around the world as I can (over 2,900 so far). Ok, that is the real world. Meanwhile I have spent over 8 years compiling over 5.8 meg of text data on all the woods of the world. That got so large that learning some basic PHP and MySQL was most welcome so I could build a new database driven home for all this research. I am still slow at it but getting there. The original premise was to find evidence of as many species of woods in the world I can. The more names identified, the more successful the project. I have named the project TAXA for ease of conversation (short for Taxonomy). You are most welcome to take a look at what I have so far at www.prowebcanada.com/taxa. It is 95% dynamically driven. So far I am reporting about 6,500 botanical wood names and, as said above, the more I can report, the more successful is the project. I have a file of all the woods in the second largest wood collection in the world, the Tervuren wood collection in the Netherlands with over 11,300 wood names even after cleaning out all duplicates. That is almost twice the number I am reporting now so porting all the new wood names from Tervuren to the 'species' table where I keep the reported data would be a major desirable advancement in the project. At one point I was able to add all the Tervuren records to the species table but over 3,000 duplicates also formed. They were not in the Tervuren file in the first place but represent the same wood names common to both files. It is common sense that there would be woods common to both that when merged would create new duplicates. At one point and with the help of others from another forum, I may very well have finally got the proper SQL statement. When I ran it, though, the system said (semi-amusingly at first) ----- that it had gone away! After looking up on the Net what could have have done this, one reason is that the MySQL timeout lapses and probably because of the large size of files I am running. I am running this on a rented account on Godaddy so I cannot go about trying to adjust any config file. For safety, I copied the tervuren.sql file as tervuren_target.sql and the species.sql file as species_master.sql tp use as working files just to make sure I protect the original files from destruction or damage. Later I can name the species_master back to just species.sql once I am happy all worked well. The species file has about 18 columns in it but only 5 columns match the columns in the Tervuren file (name for name and collation also). The rest of the columns are just along for the ride, so to speak. The common key in both is the 'species_name" columns in both. I am not sure it is at all proper to call one a primary key and the other a foreign key since there really is no relational connection to them. One is just more data for the other and can disappear after, never to be referred to the working code in the application. I have been very surprised and flabbergasted on how hard it can be to append records from one large table into another (with same column names plus others) without generating NEW duplicates in the first place. Watch out thinking that a SELECT DISTINCT statement may do the job because absolutely NO records in the species table must get destroyed in the process and there is no way (well, that I know of) to tell the 'DISTINCT" command this. Yes, the original 'species' table has duplicates in it even before all this but, trust me ---- they have to be removed the long hard way manually record by record or I will lose precious information. It is more important to just make sure no NEW duplicates form through bringing in new names in the tervuren_target.species_name into species.species_name. I am hoping and thinking that a straight SQL solution should work --- except for that nasty timeout. How do I get past that? Could it mean that I may have to turn to a PHP plus SQL method?? Or ..... would I have to break up the Tervuren files into a few smaller ones and run them independently (hope not....)" So far, what seems should be easy has proven to be unexpectedly tricky. I appreciate any help you can give but start from the assumption that this may be harder to do right than it may seem on the surface. By the way --- I am running a quad 64 bit system with Windows 7, so at least I have some fairly hefty power on the client end. I have a direct ethernet cable feeding a cable connection to the Internet. Once I get an algorithm and code working for this, I also have many other lists to process that could make the 'species' table grow even more. It could be equivalent to (ahem) lighting a rocket under my project (especially compared to do this record by record manually)! This is my first time in this forum, so I do not know how I can receive any replies. Do I have to to come back here periodically or are replies emailed out also? It would be great if you CC'd copies to me at billmudry at rogers.com :-) Much thanks for your patience and help, Bill Mudry Mississauga, Ontario Canada (next to Toronto).

• How do you get XML::Pastor to set xsi:type for programmatically generated elements?

  - by Derrick

  I'm learning how to use Perl as an automation test framework tool for a Java web service and running into trouble generating xml requests from the Pastor generated modules. The problem is that when including a type that extends from the required type for an element, the xsi:type is not included in the generated xml string. Say, for example, I want to generate the following xml request from the modules that XML::Pastor generated from my xsd: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <PromptAnswersRequest xmlns="http://mycompany.com/api"> <Uri>/some/url</Uri> <User ref="1"/> <PromptAnswers> <PromptAnswer xsi:type="textPromptAnswer" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <Prompt ref="2"/> <Children> <PromptAnswer xsi:type="choicePromptAnswer"> <Prompt ref="1"/> <Choice ref="2"/> </PromptAnswer> </Children> <Value>totally</Value> </PromptAnswer> </PromptAnswers> </PromptAnswersRequest> What I'm getting currently is this: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <PromptAnswersRequest xmlns="http://mycompany.com/api"> <Uri>/some/url</Uri> <User ref="1"/> <PromptAnswers> <PromptAnswer> <Prompt ref="2"/> <Children> <PromptAnswer> <Prompt ref="1"/> <Choice ref="2"/> </PromptAnswer> </Children> <Value>totally</Value> </PromptAnswer> </PromptAnswers> </PromptAnswersRequest> Here are some relavent snippets from the xsd: <xs:complexType name="request"> <xs:sequence> <xs:element name="Uri" type="xs:anyURI"/> </xs:sequence> </xs:complexType> <xs:complexType name="promptAnswersRequest"> <xs:complexContent> <xs:extension base="api:request"> <xs:sequence> <xs:element name="User" type="api:ref"/> <xs:element name="PromptAnswers" type="api:promptAnswerList"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="promptAnswerList"> <xs:sequence> <xs:element name="PromptAnswer" type="api:promptAnswer" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:complexType name="promptAnswer" abstract="true"> <xs:sequence> <xs:element name="Prompt" type="api:ref"/> <xs:element name="Children" type="api:promptAnswerList" minOccurs="0"/> </xs:sequence> </xs:complexType> <xs:complexType name="textPromptAnswer"> <xs:complexContent> <xs:extension base="promptAnswer"> <xs:sequence> <xs:element name="Value" type="api:nonEmptyString" minOccurs="0"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> And here are relavent parts of the script: my $promptAnswerList = new My::API::Type::promptAnswerList; my @promptAnswers; my $promptAnswerList2 = new My::API::Type::promptAnswerList; my @textPromptAnswerChildren; my $textPromptAnswer = new My::API::Type::textPromptAnswer; my $textPromptAnswerRef = new My::API::Type::ref; $textPromptAnswerRef->ref('2'); $textPromptAnswer->Prompt($textPromptAnswerRef); my $choicePromptAnswer = new My::API::Type::choicePromptAnswer; my $choicePromptAnswerPromptRef = new My::API::Type::ref; my $choicePromptAnswerChoiceRef = new My::API::Type::ref; $choicePromptAnswerPromptRef->ref('1'); $choicePromptAnswerChoiceRef->ref('2'); $choicePromptAnswer->Prompt($choicePromptAnswerPromptRef); $choicePromptAnswer->Choice($choicePromptAnswerChoiceRef); push(@textPromptAnswerChildren, $choicePromptAnswer); $promptAnswerList2->PromptAnswer(@textPromptAnswerChildren); $textPromptAnswer->Children($promptAnswerList2); $textPromptAnswer->Value('totally'); push(@promptAnswers, $pulseTextPromptAnswer); push(@promptAnswers, $textPromptAnswer); I haven't seen this addressed anywhere in the documentation for the XML::Pastor modules, so if anyone can point me at a good reference for its use it would be greatly appreciated. Also, I'm only using XML::Pastor because I don't know of any other modules that can do this, so if any of you know of something either easier to use, or more well maintained, please let me know about that too!

• Access Violation

I tried to look up the reasons and most of them dealt with with the size of the location I'm writing to and what I'm copying from. Otherwise, I have absolutely no idea. Any help would be nice. The game is GunRoar and the base address "0x409A7E" is where the DEC function is.

• Need some suggestions on my softwares architecture. [Code review]

  - by Sergio Tapia

  I'm making an open source C# library for other developers to use. My key concern is ease of use. This means using intuitive names, intuitive method usage and such. This is the first time I've done something with other people in mind, so I'm really concerned about the quality of the architecture. Plus, I wouldn't mind learning a thing or two. :) I have three classes: Downloader, Parser and Movie I was thinking that it would be best to only expose the Movie class of my library and have Downloader and Parser remain hidden from invocation. Ultimately, I see my library being used like this. using FreeIMDB; public void Test() { var MyMovie = Movie.FindMovie("The Matrix"); //Now MyMovie would have all it's fields set and ready for the big show. } Can you review how I'm planning this, and point out any wrong judgement calls I've made and where I could improve. Remember, my main concern is ease of use. Movie.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Drawing; namespace FreeIMDB { public class Movie { public Image Poster { get; set; } public string Title { get; set; } public DateTime ReleaseDate { get; set; } public string Rating { get; set; } public string Director { get; set; } public List<string> Writers { get; set; } public List<string> Genres { get; set; } public string Tagline { get; set; } public string Plot { get; set; } public List<string> Cast { get; set; } public string Runtime { get; set; } public string Country { get; set; } public string Language { get; set; } public Movie FindMovie(string Title) { Movie film = new Movie(); Parser parser = Parser.FromMovieTitle(Title); film.Poster = parser.Poster(); film.Title = parser.Title(); film.ReleaseDate = parser.ReleaseDate(); //And so an so forth. } public Movie FindKnownMovie(string ID) { Movie film = new Movie(); Parser parser = Parser.FromMovieID(ID); film.Poster = parser.Poster(); film.Title = parser.Title(); film.ReleaseDate = parser.ReleaseDate(); //And so an so forth. } } } Parser.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; using HtmlAgilityPack; namespace FreeIMDB { /// <summary> /// Provides a simple, and intuitive way for searching for movies and actors on IMDB. /// </summary> class Parser { private Downloader downloader = new Downloader(); private HtmlDocument Page; #region "Page Loader Events" private Parser() { } public static Parser FromMovieTitle(string MovieTitle) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindMovie(MovieTitle); return newParser; } public static Parser FromActorName(string ActorName) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindActor(ActorName); return newParser; } public static Parser FromMovieID(string MovieID) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindKnownMovie(MovieID); return newParser; } public static Parser FromActorID(string ActorID) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindKnownActor(ActorID); return newParser; } #endregion #region "Page Parsing Methods" public string Poster() { //Logic to scrape the Poster URL from the Page element of this. return null; } public string Title() { return null; } public DateTime ReleaseDate() { return null; } #endregion } } ----------------------------------------------- Do you guys think I'm heading towards a good path, or am I setting myself up for a world of hurt later on? My original thought was to separate the downloading, the parsing and the actual populating to easily have an extensible library. Imagine if one day the website changed its HTML, I would then only have to modifiy the parsing class without touching the Downloader.cs or Movie.cs class. Thanks for reading and for helping!

• PHP: How to automate building a 100 <UL>/<LI> menuitems, while keeping the Menu Structure File Flat / Simply Managable?

  - by Sam

  Above: current "stupid" menu. (entire ul/li menu for javascript menu system) + (some li lines as page-specific submenu) Hi folks! With passion for automation and elegancy, but limited knowledge/knowhow, im stuck with "my hands in my hair" as we Dutch say, for my current menu system works perfectly, but is a pain in the a*s to update! So, i would appreciate it greatly, if you can suggest how to automate this in php: how to let the php generate the html menu code basing on a flat menu input file with TABS indented. OLD SITUATION <ul> <!-- about 100 of these <li>....</li> lines --> <li><a href="carrot.php"><p class="mnu" style="background-position:0 -820px"><? echo __("carrot juice") ?></p></a></li> <!-- lots of data, with only little bit thats really the menu itself--> </ul a javascript file reads a ul/li structure as input to build menu of format in that ul/li, the items with a hyperlink and sprite-bg position represent webpages, (inside LI) while items without hyperlink and sprite-bg are just headers of that menusection, (inside H6) to highlight the current page in the menu, the javascript menumaker uses an id number. this number corresponds to the consequtive li that is a webpage, skips h6 headers correctly. these h6 headers are only there for when importing sections of the same menu as submenu. non-li headers are not shown in menu, nore counted by the javascript menu for their ID. to know which page should be shown, i have to count from ID 0, the li items till finding the current webpage in the li structure and then manually put it in each webpage! BUT: changing an item in li order, means stupidly re-counting their entire li again! each webpage has an icon (= sprite bg-position numer), which is also used in the webpage. INTENDED RESULT I dream of, once setting what the current webpage is (e.g carrot.php) the menu system automatically "finds" and "counts" the li's and returns the id nr (for proper highlight of main menu); generates the entire menu html, and depending on which headings are set for submenu, (e.g. meals, drinks) generates those submenu (entire section below each given header); ginally adds h5 highlight inside the li of that submenu item. For the menu, i wish an easily readable, simple plain txt menu that is indented with tabs, (each tab is one depth for example) and further tabs follow for url and sprite position of icon. MY DREAM MENU-MANAGEMENT FILE |>TAB SEPARATED/INDENTED FLATMENU FILE |MUST BE CALCULATED BY PHP: |>MENUTEXT============URL=============SPRITE=====|ID===TAG================== |>about "#" -520 |00 li |> INFORMATION |—— h6 |> physical state "physical.php" -920 |01 li |> mental health "mental.php" -10 |02 li |> |>apetite "#" -1290 |03 li |> meals "#" -600 |04 li |> COLD MEAL |—— h6 |> egg salade "salad.php" -1040 |05 li |> salmon fish "salmon.php" -540 |06 li |> HOT MEAL |—— h6 |> spare ribs "spareribs.php" -120 |07 li |> di macaroni "macaroni.php" -870 |08 li |> |> drinks "#" -230 |09 li |> JUCY DRINK |—— h6 |> carrot juice "carrot.php" -820 |10 li |> mango hive "mango.php" -270 |11 li DESIRED CHRONOLOGY php outputs the entire ul/li html so the javascript can show the menu: webpage items go inside li tags, and header items go inside h6 tags, e.g. <h6>JUCY DRINK</h6> Each website page has a url filename [eg: salad.php]. Based on this given fact, the php menu generator detects the pagename, gives the IDnr of the position of that page according to the li-item nr and sets variable for javascript to highlight current menu item. the menu items below the specified headers are loaded as submenu in which the current page.php is wrapped inside h5 to highlight current page in submenu: e.g. (<li><h5><a href="carrot.php"><p>..etc..</p></h5></li> Question Which methods / steps / (chronological)ways are there for doing this? I am no good in php programming, but am learning it so please dont write any code without a line of comment why I should use that method etc. Where do I start? If I am unclear in my question, please ask. Thanks. Much appreciated!! Concrete Task List from the provided Comments/Answers, sofar: (RobertB) First, get some PHP code working that can read through a tab-delimited file and put the data into an appropriate data structure. NOW WORKING AT THIS

• Creating a new plugin for mpld3

  - by sjp14051

  Toward learning how to create a new mpld3 plugin, I took an existing example, LinkedDataPlugin (http://mpld3.github.io/examples/heart_path.html), and modified it slightly by deleting references to lines object. That is, I created the following: class DragPlugin(plugins.PluginBase): JAVASCRIPT = r""" mpld3.register_plugin("drag", DragPlugin); DragPlugin.prototype = Object.create(mpld3.Plugin.prototype); DragPlugin.prototype.constructor = DragPlugin; DragPlugin.prototype.requiredProps = ["idpts", "idpatch"]; DragPlugin.prototype.defaultProps = {} function DragPlugin(fig, props){ mpld3.Plugin.call(this, fig, props); }; DragPlugin.prototype.draw = function(){ var patchobj = mpld3.get_element(this.props.idpatch, this.fig); var ptsobj = mpld3.get_element(this.props.idpts, this.fig); var drag = d3.behavior.drag() .origin(function(d) { return {x:ptsobj.ax.x(d[0]), y:ptsobj.ax.y(d[1])}; }) .on("dragstart", dragstarted) .on("drag", dragged) .on("dragend", dragended); patchobj.path.attr("d", patchobj.datafunc(ptsobj.offsets, patchobj.pathcodes)); patchobj.data = ptsobj.offsets; ptsobj.elements() .data(ptsobj.offsets) .style("cursor", "default") .call(drag); function dragstarted(d) { d3.event.sourceEvent.stopPropagation(); d3.select(this).classed("dragging", true); } function dragged(d, i) { d[0] = ptsobj.ax.x.invert(d3.event.x); d[1] = ptsobj.ax.y.invert(d3.event.y); d3.select(this) .attr("transform", "translate(" + [d3.event.x,d3.event.y] + ")"); patchobj.path.attr("d", patchobj.datafunc(ptsobj.offsets, patchobj.pathcodes)); } function dragended(d, i) { d3.select(this).classed("dragging", false); } } mpld3.register_plugin("drag", DragPlugin); """ def __init__(self, points, patch): print "Points ID : ", utils.get_id(points) self.dict_ = {"type": "drag", "idpts": utils.get_id(points), "idpatch": utils.get_id(patch)} However, when I try to link the plugin to a figure, as in plugins.connect(fig, DragPlugin(points[0], patch)) I get an error, 'module' is not callable, pointing to this line. What does this mean and why doesn't it work? Thanks. I'm adding additional code to show that linking more than one Plugin might be problematic. But this may be entirely due to some silly mistake on my part, or there is a way around it. The following code based on LinkedViewPlugin generates three panels, in which the top and the bottom panel are supposed to be identical. Mouseover in the middle panel was expected to control the display in the top and bottom panels, but updates occur in the bottom panel only. It would be nice to be able to figure out how to reflect the changes in multiple panels.

• jQuery getting these functions to work together

  - by brett

  I'm new to jQuery and have tried looking around for an answer on how to do this. I have 2 functions and I would like both to work together. The one function is submitHandler and its used to hide a form and at the same time add a class to a hidden element to unhide it - ie a thank you for submitting h1. The other function is to grab the input data and display it onsubmit in the form. So the problem is that I can get that one to work but then the other doesnt. Ie on form submit I can see the data input but not the h1 Thank you message. Here are the functions: SubmitHandler: submitHandler: function() { $("#content").empty(); $("#content").append( "<p>If you want to be kept in the loop...</p>" + "<p>Or you can contact...</p>" ); $('h1.success_').removeClass('success_').addClass('success_form'); $('#contactform').hide(); }, onsubmit="return inputdata()" function inputdata(){ var usr = document.getElementById('contactname').value; var eml = document.getElementById('email').value; var msg = document.getElementById('message').value; document.getElementById('out').innerHTML = usr + " " + eml + msg; document.getElementById('out').style.display = "block"; return true; }, The form uses PHP and jQuery - I dont know about AJAX but after some reading even less sure. Please help me out I dont know what I'm doing and at the moment I am learning but its a long road for me still. Thank you The form: <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" id="contactform" onsubmit="return inputdata()"> <div class="_required"><p class="label_left">Name*</p><input type="text" size="50" name="contactname" id="contactname" value="" class="required" /></div><br/><br/> <div class="_required"><p class="label_left">E-mail address*</p><input type="text" size="50" name="email" id="email" value="" class="required email" /></div><br/><br/> <p class="label_left">Message</p><textarea rows="5" cols="50" name="message" id="message" class="required"></textarea><br/> <input type="submit" value="submit" name="submit" id="submit" /> </form> The PHP bit: <?php $subject = "Website Contact Form Enquiry"; //If the form is submitted if(isset($_POST['submit'])) { //Check to make sure that the name field is not empty if(trim($_POST['contactname']) == '') { $hasError = true; } else { $name = trim($_POST['contactname']); } //Check to make sure sure that a valid email address is submitted if(trim($_POST['email']) == '') { $hasError = true; } else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$", trim($_POST['email']))) { $hasError = true; } else { $email = trim($_POST['email']); } //Check to make sure comments were entered if(trim($_POST['message']) == '') { $hasError = true; } else { if(function_exists('stripslashes')) { $comments = stripslashes(trim($_POST['message'])); } else { $comments = trim($_POST['message']); } } //If there is no error, send the email if(!isset($hasError)) { $emailTo = '[email protected]'; //Put your own email address here $body = "Name: $name \n\nEmail: $email \n\nComments:\n $comments"; $headers = 'From: My Site <'.$emailTo.'>' .

The Jquery Validate bit: $(document).ready(function(){ $('#contactform').validate({ showErrors: function(errorMap, errorList) { //restore the normal look $('#contactform div.xrequired').removeClass('xrequired').addClass('_required'); //stop if everything is ok if (errorList.length == 0) return; //Iterate over the errors for(var i = 0;i < errorList.length; i++) $(errorList[i].element).parent().removeClass('_required').addClass('xrequired'); }, Here is the full jQuery bit: $(document).ready(function(){ $('#contactform').validate({ showErrors: function(errorMap, errorList) { //restore the normal look $('#contactform div.xrequired').removeClass('xrequired').addClass('_required'); //stop if everything is ok if (errorList.length == 0) return; //Iterate over the errors for(var i = 0;i < errorList.length; i++) $(errorList[i].element).parent().removeClass('_required').addClass('xrequired'); }, submitHandler: function() { $('h1.success_').removeClass('success_').addClass('success_form'); $("#content").empty(); $("#content").append('#sadhu'); $('#contactform').hide(); }, }); }); Latest edit - Looks like this: $(document).ready(function(){ $('#contactform').validate({ showErrors: function(errorMap, errorList) { //restore the normal look $('#contactform div.xrequired').removeClass('xrequired').addClass('_required'); //stop if everything is ok if (errorList.length == 0) return; //Iterate over the errors for(var i = 0;i < errorList.length; i++) $(errorList[i].element).parent().removeClass('_required').addClass('xrequired'); }, function submitHandler() { $('h1.success_').removeClass('success_').addClass('success_form'); $("#content").empty(); $("#content").append('#sadhu'); $('#contactform').hide(); }, function inputdata() { var usr = document.getElementById('contactname').value; var eml = document.getElementById('email').value; var msg = document.getElementById('message').value; document.getElementById('out').innerHTML = usr + " " + eml + msg; document.getElementById('out').style.display = "block"; }, $(document).ready(function(){ $('#contactForm').submit(function() { inputdata(); submitHandler(); }); }); });

• Understanding the passing of data/life of a script in web development/CodeIgniter

  - by Pete Jodo

  I hope I worded the title accurately enough but I typically use Java and don't have much experience in Web Development/PHP/CodeIgniter. I have a difficult time understanding the life cycle of a script as I found out trying to implement a certain feature to a website I am developing (as a means of learning how to). I'll first describe the feature I tried implementing and then the problem I ran into that made me question my fundamental understanding of how scripts work since I'm used to typical OOP. Ok so here goes... I have a webpage that has 2 basic tasks a user can do, create and delete an entry. What I attempted to implement was a way to time a user how long it takes them to complete a certain task. The way I did this was have a homepage where there would be a list of tasks a user to choose from (in this case 2, create and delete). A user would click a task which would link to the 'true' homepage where the user then would be expected to complete the task. My script looks like this: <?php class Site extends CI_Controller { var $task1; var $tasks = array( "task1" => NULL, "date1" => 0, "date2" => 0, "diff" => 0); function __construct() { parent::__construct(); include 'timetask.php'; $this->task1 = new TimeTask("create"); } function index() { $this->tasks['task1'] = $this->task1->getTask(); $this->tasks['diff'] = $this->task1->getTimeDiff(); if($this->tasks['diff'] == NULL) { $this->tasks['diff'] = 0; } $this->load->view('usability_test', $this->tasks); } function origIndex() { $this->task1->setDate1(new DateTime()); $this->tasks['date1'] = $this->task1->getDate1()->getTimestamp(); $data = array(); if($q = $this->site_model->get_records()) { $data['records'] = $q; } $this->load->view('options_view', $data); } function create() { $this->task1->setDate2(new DateTime()); $this->tasks['date2'] = $this->task1->getDate2()->getTimestamp(); $data = array( 'author' => $this->input->post('author'), 'title' => $this->input->post('title'), 'contents' => $this->input->post('contents') ); $this->site_model->add_record($data); $this->index(); } I only included create to keep it short. Then I also have the TimeTask class, that actually another StackOverflow so kindly helped me with: <?php class TimeTask { private $task; /** * @var DateTime */ private $date1, $date2; function __construct($currTask) { $this->task = $currTask; } public function getTimeDiff() { $hasDiff = $this->date1 && $this->date2; if ($hasDiff) { return $this->date2->getTimestamp() - $this->date1->getTimestamp(); } else { return NULL; } } public function __toString() { return (string) $this->getTimeDiff(); } /** * @return \DateTime */ public function getDate1() { return $this->date1; } /** * @param \DateTime $date1 */ public function setDate1(DateTime $date1) { $this->date1 = $date1; } /** * @return \DateTime */ public function getDate2() { return $this->date2; } /** * @param \DateTime $date2 */ public function setDate2(DateTime $date2) { $this->date2 = $date2; } /** * @return get current task */ public function getTask() { return $this->task; } } ?> I don't think posting the views is necessary for the question but here is atleast how the links are made. ...and... id", $row-title); ? Now there's no error in the code but it doesn't do what I expect of it and the reason I assume why is because that each time a function of the script is called via a new page it is NOT the same instance of the script called previously so any previously created objects are no longer there. This confuses me and leaves me quite unsure of how to implement this gracefully. Some ways I would guess of how to do this is by passing the necessary data through the URL or have data saved in a database and retrieve it later to compare the times. What would be a recommended way to do, not just this, but anything that needs previously created data? Also, am I correct to think that a script is only 'alive' for one webpage at a time? Thanks!

• listbox isSelected databinding in DataTemplate

  - by Kinmarui

  I try to simply databind IsSelected property with IsSelected field in my class. But after I change the value in code its doesn't change the property, neither does clicking on ListBoxItem change the field value. XAML: <FlipView ItemsSource="{Binding Source={StaticResource itemsViewSource}}" ... > <FlipView.ItemTemplate> <DataTemplate> <UserControl Loaded="StartLayoutUpdates" Unloaded="StopLayoutUpdates"> <!-- other controls --> <ListBox Grid.Row="1" Grid.ColumnSpan="3" SelectionMode="Multiple" VerticalAlignment="Center" ItemsSource="{Binding Answers}"> <ListBox.Resources> <local:LogicToText x:Key="logToText" /> </ListBox.Resources> <!-- bind IsSelected only in one way from code to content --> <ItemsControl.ItemTemplate> <DataTemplate> <ListBoxItem IsSelected="{Binding IsSelected, Mode=TwoWay, Converter={StaticResource logToText}}" Content="{Binding IsSelected, Mode=TwoWay, Converter={StaticResource logToText}}"> </ListBoxItem> </DataTemplate> </ItemsControl.ItemTemplate> <!-- not working at all <ListBox.Resources> <Style TargetType="ListBoxItem"> <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"/> <Setter Property="Content" Value="{Binding IsSelected, Mode=TwoWay}"/> </Style> </ListBox.Resources>--> </ListBox> </UserControl> </DataTemplate> </FlipView.ItemTemplate> </FlipView> Code: Answers private ObservableCollection<PrawoJazdyDataAnswer> _answers = new ObservableCollection<PrawoJazdyDataAnswer>(); public ObservableCollection<PrawoJazdyDataAnswer> Answers { get { return this._answers; } } Single item(Answer) public class PrawoJazdyDataAnswer : NPCHelper// PrawoJazdy.Common.BindableBase { public PrawoJazdyDataAnswer(String ans, bool ansb) { this._ans = ans; this._isSelected = ansb; } public override string ToString() { return _isSelected.ToString(); } //Only For debug purposes normally return _ans; private string _ans; public string Ans { get { return this._ans; } //set { this.SetProperty(ref this._ans, value); } } private bool _isSelected; public bool IsSelected { get { return this._isSelected; } set { _isSelected = value; FirePropertyChanged("IsSelected"); //this.SetProperty(ref this._isSelected, value); } } } FirePropertyChanged public class NPCHelper : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public void FirePropertyChanged(string prop) { if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(prop)); } } Converter(which sometimes seems to be needed and others not..., I tried ~10 approaches from different tutorials/examples) public class LogicToText : IValueConverter { /// <summary> /// /// </summary> public object Convert(object value, Type targetType, object parameter, string language) { //if (value == null || (bool)value == false) // return "False"; return value.ToString(); } /// <summary> /// /// </summary> public object ConvertBack(object value, Type targetType, object parameter, string language) { return value.ToString().Contains("True") ? true : false; } Thanks in advance, and sorry for my English(still learning). @edit Thanks for quick reply. For test purposes i created a button and text block: It's in other controls part (above list box, but in FlipView) <Button Click="spr" >Sprawdz</Button> <TextBlock Text="{Binding Answers[0].IsSelected, Mode=TwoWay}" > </TextBlock> Click method private void spr(object sender, RoutedEventArgs e) { var ans = ((PrawoJazdyDataQuestion)this.flipView.SelectedItem).Answers; foreach (var item in ans) item.IsSelected = item.IsSelected ? false : true; } As I wrote when i'm changing data from code side its change text, but not appearance of ListBoxItem, and if i just select it on ListBox its doesn't change the date i textblock neither in ListBox itself.
