  • Am I suffering "divitis"? (CSS especialist needed)

    - by janoChen
    I've read lots of articles that condemn the excessive use of divs. I have a feeling that I might be doing that in the following mark up: HTML: <div id="header"> <div class="container"> <div id="banner"> <h1><a href="http://widerdesign.co.nr/">wider design</a></h1> <ul id="lang"> <li><a href="index.php">English</a></li> <li><a href="es/index.php">Español</a></li> <li><a href="tw/index.php">??(??)</a></li> <li><a href="cn/index.php">??(??)</a></li> </ul> </div> <div id="intro"> <div id="tagline"> <h2>Nulla vitae tortor mauris</h2> <p>Pellentesque faucibus est eu tellus varius in susc...</p> </div> <div id="about"> <h2>right</h2> <p>Pellentesque faucibus est eu tellus varius in susc...</p> </div> </div><!-- #intro --> </div><!-- .container --> </div><!-- #header --> CSS: .container { margin: 0 auto; overflow: hidden; width: 960px; } /* header */ #header { background: #EEE; } #header h1 { float: left; } #header h2, #header a, #header p { color: #999; } #header h1 a { background: url(../images/logo.png) no-repeat scroll 0 0; float: left; height: 30px; text-indent: -9999px; width: 500px; } #banner { border-bottom: 1px solid #DDD; padding: 0 0 15px 0; margin: 30px 0 30px 0; overflow: hidden; width: 960px; } #lang { float: right; padding: 9px 0 0 0; } #lang li { float: left; margin: 0 0 0 20px; } #lang li a { font-size: 10px; } /* intro */ #intro { overflow: hidden; padding: 0 0 30px 0; } #tagline { float: left; margin: 0 40px 0 0; width: 540px; /* 560 */ } #tagline h2 { font-size: 24px; } #about { float: right; width: 380px; } Explanation of the use of those divs: header: Defines the background color which expands until the end of the window (lies outside of the div .container). container: centers the content (but not the background). banner: to define the background or border color around ul#lang and h1. intro: same as above but for #tagline and #about (otherwise I have to define say padding or margin for tagline and about individually). Am I overusing divs? Can this be simplified?

  • How do I return a message if $_GET is null or does not match any database entries?

    - by CT
    I am working on designing an IT Asset database. Here I am working on a page used to view details on a specific asset determined by an asset id. Here I grab $id from $_GET["id"]; When $id is null, the page does not load. When $id does not match any entry within the database, the page loads but no asset table is printed. In both these cases, I would like to display a message like "There is no database entry for that Asset ID" How would this be handled? Thank you. <?php /* * View Asset * */ # include functions script include "functions.php"; $id = $_GET["id"]; ConnectDB(); $type = GetAssetType($id); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link rel="stylesheet" type="text/css" href="style.css" /> <title>Wagman IT Asset</title> </head> <body> <div id="page"> <div id="header"> <img src="images/logo.png" /> </div> </div> <div id="content"> <div id="container"> <div id="main"> <div id="menu"> <ul> <table width="100%" border="0"> <tr> <td width="15%"></td> <td width="30%%"><li><a href="index.php">Search Assets</a></li></td> <td width="30%"><li><a href="addAsset.php">Add Asset</a></li></td> <td width="25%"></td> </tr> </table> </ul> </div> <div id="text"> <ul> <li> <h1>View Asset</h1> </li> </ul> <br /> <?php switch ($type){ case "Server": $result = QueryServer($id); $ServerArray = GetServerData($result); PrintServerTable($ServerArray); break; case "Desktop"; break; case "Laptop"; break; } ?> </div> </div> </div> <div class="clear"></div> <div id="footer" align="center"> <p>&nbsp;</p> </div> </div> <div id="tagline"> Wagman Construction - Bridging Generations since 1902 </div> </body> </html>

  • jQuery: Div elements are not showing up

    - by Legend
    I am adapting the Coverflow technique to work with a div. Following is the html: <html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> <style type="text/css" media="screen"> body,html { margin: 0; padding: 0; background: #000; height: 100%; color: #eee; font-family: Arial; font-size: 10px; } div.magnifyme { height: 80px; padding: 80px; position: absolute; top: 0px; left: 0px; width: 8000px; } div.wrapper { margin: 0px; height: 470px; /*border: 2px solid #999;*/ overflow: hidden; padding-left: 40px; right: 1px; width: 824px; position: relative; } div.container {position: relative; width: 854px; height: 480px; background: #000; margin: auto;} div.nav {position: absolute; top: 10px; width: 20%; height: 10%; right: 1px; } div.magnifyme div { position: absolute; width: 300px; height: 280px; float: left; margin: 5px; position: relative; border: 2px solid #999; background: #500; } </style> <script type="text/javascript" src="jquery-1.3.2.js"></script> <script type="text/javascript" src="ui.coverflow.js"></script> <script type="text/javascript"> $(function() { $("div.magnifyme").coverflow(); $("#add").click(function() { location.reload(); $(".magnifyme").append("<div id=\"div5\">hello world</div>"); $("div.magnifyme").coverflow(); }); }); </script> </head> <body> <div class="container"> <div class="wrapper"> <div class="magnifyme"> <div id="div0">This is div 0</div> <div id="div1">This is div 1</div> <div id="div2">This is div 2</div> <div id="div3">This is div 3</div> <div id="div4">This is div 4</div> </div> </div> <div class="nav"> <button type="button" id="add">Add to Deck</button> </div> </div> </body> </html> The coverflow function (included as a js file in the head section) is here. When I click the button, I was expecting it to add a DIV to the already present deck. For some reason, it doesn't show the newly added DIV. I tried calling the coverflow() function after I added the new element but that didn't work either. Is there any way I can make this work?

  • WPF items not visible when grouping is applied

    - by Tri Q
    Hi, I'm having this strange issue with my ItemsControl grouping. I have the following setup: <ItemsControl Margin="3" ItemsSource="{Binding Communications.View}" > <ItemsControl.GroupStyle> <GroupStyle> <GroupStyle.ContainerStyle> <Style TargetType="{x:Type GroupItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type GroupItem}"> <Expander> <Expander.Header> <Grid> <Grid.ColumnDefinitions > <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <TextBlock Text="{Binding ItemCount, StringFormat='{}[{0}] '}" FontWeight="Bold" /> <TextBlock Grid.Column="1" Text="{Binding Name, Converter={StaticResource GroupingFormatter}, StringFormat='{}Subject: {0}'}" FontWeight="Bold" /> </Grid> </Expander.Header> <ItemsPresenter /> </Expander> </ControlTemplate> </Setter.Value> </Setter> </Style> </GroupStyle.ContainerStyle> </GroupStyle> </ItemsControl.GroupStyle> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition /> </Grid.RowDefinitions> <TextBlock FontWeight="Bold" Text="{Binding Inspector, Converter={StaticResource NameFormatter}, StringFormat='{}From {0}:'}" Margin="3" /> <TextBlock Text="{Binding SentDate, StringFormat='{}{0:dd/MM/yy}'}" Grid.Row="1" Margin="3"/> <TextBlock Text="{Binding Message }" Grid.Column="1" Grid.RowSpan="2" Margin="3"/> <Button Command="vm:CommunicationViewModel.DeleteMessageCommand" CommandParameter="{Binding}" HorizontalAlignment="Right" Grid.Column="2">Delete</Button> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> In my ViewModel, I expose a CollectionViewSource named 'Communications'. I proceed to adding a grouping patter like so: Communications.GroupDescriptions.Add(new PropertyGroupDescription("Subject")); Now, the problem i'm experience is the grouping work fine, but I can't see any items inside the groups. What am I doing wrong? Any pointers would be much appreciated.

  • What is the fastest way to Initialize a multi-dimensional array to non-default values in .NET?

    - by AMissico
    How do I initialize a multi-dimensional array of a primitive type as fast as possible? I am stuck with using multi-dimensional arrays. My problem is performance. The following routine initializes a 100x100 array in approx. 500 ticks. Removing the int.MaxValue initialization results in approx. 180 ticks just for the looping. Approximately 100 ticks to create the array without looping and without initializing to int.MaxValue. Routines similiar to this are called a few hundred-thousand to several million times during a "run". The array size will not change during a run and arrays are created one-at-a-time, used, then discarded, and a new array created. A "run" which may last from one minute (using 10x10 arrays) to forty-five minutes (100x100). The application creates arrays of int, bool, and struct. There can be multiple "runs" executing at same time, but are not because performance degrades terribly. I am using 100x100 as a base-line. I am open to suggestions on how to optimize this non-default initialization of an array. One idea I had is to use a smaller primitive type when available. For instance, using byte instead of int, saves 100 ticks. I would be happy with this, but I am hoping that I don't have to change the primitive data type. public int[,] CreateArray(Size size) { int[,] array = new int[size.Width, size.Height]; for (int x = 0; x < size.Width; x++) { for (int y = 0; y < size.Height; y++) { array[x, y] = int.MaxValue; } } return array; } Down to 450 ticks with the following: public int[,] CreateArray1(Size size) { int iX = size.Width; int iY = size.Height; int[,] array = new int[iX, iY]; for (int x = 0; x < iX; x++) { for (int y = 0; y < iY; y++) { array[x, y] = int.MaxValue; } } return array; } Down to approximately 165 ticks after a one-time initialization of 2800 ticks. (See my answer below.) If I can get stackalloc to work with multi-dimensional arrays, I should be able to get the same performance without having to intialize the private static array. private static bool _arrayInitialized5; private static int[,] _array5; public static int[,] CreateArray5(Size size) { if (!_arrayInitialized5) { int iX = size.Width; int iY = size.Height; _array5 = new int[iX, iY]; for (int x = 0; x < iX; x++) { for (int y = 0; y < iY; y++) { _array5[x, y] = int.MaxValue; } } _arrayInitialized5 = true; } return (int[,])_array5.Clone(); } Down to approximately 165 ticks without using the "clone technique" above. (See my answer below.) I am sure I can get the ticks lower, if I can just figure out the return of CreateArray9. public unsafe static int[,] CreateArray8(Size size) { int iX = size.Width; int iY = size.Height; int[,] array = new int[iX, iY]; fixed (int* pfixed = array) { int count = array.Length; for (int* p = pfixed; count-- > 0; p++) *p = int.MaxValue; } return array; }

    I'm getting no improvement in speed when using Ehcache with Hibernate Here are the results I get when i run the test below.

  • How to convert an ORM to its subclass using Hibernate ?

    - by Gaaston
    Hi everybody, For example, I have two classes : Person and Employee (Employee is a subclass of Person). Person : has a lastname and a firstname. Employee : has also a salary. On the client-side, I have a single HTML form where i can fill the person informations (like lastname and firstname). I also have a "switch" between "Person" and "Employee", and if the switch is on Employee I can fill the salary field. On the server-side, Servlets receive informations from the client and use the Hibernate framework to create/update data to/from the database. The mapping i'm using is a single table for persons and employee, with a discriminator. I don't know how to convert a Person in an Employee. I firstly tried to : load the Person p from the database create an empty Employee e object copy values from p into e set the salary value save e into the database But i couldn't, as I also copy the ID, and so Hibernate told me they where two instanciated ORM with the same id. And I can't cast a Person into an Employee directly, as Person is Employee's superclass. There seems to be a dirty way : delete the person, and create an employee with the same informations, but I don't really like it.. So I'd appreciate any help on that :) Some precisions : The person class : public class Person { protected int id; protected String firstName; protected String lastName; // usual getters and setters } The employee class : public class Employee extends Person { // string for now protected String salary; // usual getters and setters } And in the servlet : // type is the "switch" if(request.getParameter("type").equals("Employee")) { Employee employee = daoPerson.getEmployee(Integer.valueOf(request.getParameter("ID"))); modifyPerson(employee, request); employee.setSalary(request.getParameter("salary")); daoPerson.save(employee ); } else { Person person = daoPerson.getPerson(Integer.valueOf(request.getParameter("ID"))); modifyPerson(employee, request); daoPerson.save(person); } And finally, the loading (in the dao) : public Contact getPerson(int ID){ Session session = HibernateSessionFactory.getSession(); Person p = (Person) session.load(Person.class, new Integer(ID)); return p; } public Contact getEmployee(int ID){ Session session = HibernateSessionFactory.getSession(); Employee = (Employee) session.load(Employee.class, new Integer(ID)); return p; } With this, i'm getting a ClassCastException when trying to load a Person using getEmployee. XML Hibernate mapping : <class name="domain.Person" table="PERSON" discriminator-value="P"> <id name="id" type="int"> <column name="ID" /> <generator class="native" /> </id> <discriminator column="type" type="character"/> <property name="firstName" type="java.lang.String"> <column name="FIRSTNAME" /> </property> <property name="lastName" type="java.lang.String"> <column name="LASTNAME" /> </property> <subclass name="domain.Employee" discriminator-value="E"> <property name="salary" column="SALARY" type="java.lang.String" /> </subclass> </class> Is it clear enough ? :-/

  • Rotate rectangle around center

    - by ESoft
    I am playing with Brad Larsen's adaption of the trackball app. I have two views at a 60 degree angle to each other and was wondering how I get the rotation to be in the center of this (non-closed) rectangle?

  • Hibernate: update on parent-child relationship causes duplicate children

    - by TimmyJ
    I have a parent child relationship in which the parent has a collection of children (a set to be specific). The child collection is setup with cascade="all-delete-orphan". When I initially save the parent element everything works as expected. However, when I update the parent and save again, all the children are re-saved. This behavior leads me to believe that the parent is losing its reference to the collection of children, and therefore when persisting all the children are re-saved. It seems the only way to fix this is to not use the setter method of this child collection, but unfortunately this setter is called implicitly in my application (Spring MVC is used to bind a multi-select form element to this collection, and the setter is called by spring on the form submission). Overwriting this setter to not lose the reference (ie, do a colleciton.clear() and collection.addAll(newCollection) rather than collection = newCollection) is apparently a hibernate no-no, as is pointed out here: https://forum.hibernate.org/viewtopic.php?t=956859 Does anyone know how to circumvent this problem? I've posted some of my code below. The parent hibernate configuration: <hibernate-mapping package="org.fstrf.masterpk.domain"> <class name="ReportCriteriaBean" table="masterPkReportCriteria"> <id name="id" column="id"> <generator class="org.hibernate.id.IncrementGenerator" /> </id> <set name="treatmentArms" table="masterPkTreatmentArms" sort="org.fstrf.masterpk.domain.RxCodeComparator" lazy="false" cascade="all-delete-orphan" inverse="true"> <key column="runid"/> <one-to-many class="TreatmentArm"/> </set> </class> </hibernate-mapping> The parent object: public class ReportCriteriaBean{ private Integer id; private Set<TreatmentArm> treatmentArms; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public Set<TreatmentArm> getTreatmentArms() { return treatmentArms; } public void setTreatmentArms(Set<TreatmentArm> treatmentArms) { this.treatmentArms = treatmentArms; if(this.treatmentArms != null){ for(TreatmentArm treatmentArm : this.treatmentArms){ treatmentArm.setReportCriteriaBean(this); } } } The child hibernate configuration: <hibernate-mapping package="org.fstrf.masterpk.domain"> <class name="TreatmentArm" table="masterPkTreatmentArms"> <id name="id" column="id"> <generator class="org.hibernate.id.IncrementGenerator" /> </id> <many-to-one name="reportCriteriaBean" class="ReportCriteriaBean" column="runId" not-null="true" /> <property name="rxCode" column="rxCode" not-null="true"/> </class> </hibernate-mapping> The child object: public class TreatmentArm { private Integer id; private ReportCriteriaBean reportCriteriaBean; private String rxCode; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public ReportCriteriaBean getReportCriteriaBean() { return reportCriteriaBean; } public void setReportCriteriaBean(ReportCriteriaBean reportCriteriaBean) { this.reportCriteriaBean = reportCriteriaBean; } public String getRxCode() { return rxCode; } public void setRxCode(String rxCode) { this.rxCode = rxCode; } }

  • JPA2 adding referential contraint to table complicates criteria query with lazy fetch, need advice

    - by Quaternion
    Following is a lot of writing for what I feel is a pretty simple issue. Root of issue is my ignorance, not looking so much for code but advice. Table: Ininvhst (Inventory-schema inventory history) column ihtran (inventory history transfer code) using an old entity mapping I have: @Basic(optional = false) @Column(name = "IHTRAN") private String ihtran; ihtran is really a foreign key to table Intrnmst ("Inventory Transfer Master" which contains a list of "transfer codes"). This was not expressed in the database so placed a referential constraint on Ininvhst re-generating JPA2 entity classes produced: @JoinColumn(name = "IHTRAN", referencedColumnName = "TMCODE", nullable = false) @ManyToOne(optional = false) private Intrnmst intrnmst; Now previously I was using JPA2 to select the records/(Ininvhst entities) from the Ininvhst table where "ihtran" was one of a set of values. I used in.value() to do this... here is a snippet: cq = cb.createQuery(Ininvhst.class); ... In in = cb.in(transactionType); //Get in expression for transacton types for (String s : transactionTypes) { //has a value in = in.value(s);//check if the strings we are looking for exist in the transfer master } predicateList.add(in); My issue is that the Ininvhst used to contain a string called ihtran but now it contains Ininvhst... So I now need a path expression: this.predicateList = new ArrayList<Predicate>(); if (transactionTypes != null && transactionTypes.size() > 0) { //list of strings has some values Path<Intrnmst> intrnmst = root.get(Ininvhst_.intrnmst); //get transfermaster from Ininvhst Path<String> transactionType = intrnmst.get(Intrnmst_.tmcode); //get transaction types from transfer master In<String> in = cb.in(transactionType); //Get in expression for transacton types for (String s : transactionTypes) { //has a value in = in.value(s);//check if the strings we are looking for exist in the transfer master } predicateList.add(in); } Can I add ihtran back into the entity along with a join column that is both references "IHTRAN"? Or should I use a projection to somehow return Ininvhst along with the ihtran string which is now part of the Intrnmst entity. Or should I use a projection to return Ininvhst and somehow limit Intrnmst just just the ihtran string. Further information: I am using the resulting list of selected Ininvhst objects in a web application, the class which contains the list of Ininvhst objects is transformed into a json object. There are probably quite a few serialization methods that would navigate the object graph the problem is that my current fetch strategy is lazy so it hits the join entity (Intrnmst intrnmst) and there is no Entity Manager available at that point. At this point I have prevented the object from serializing the join column but now I am missing a critical piece of data. I think I've said too much but not knowing enough I don't know what you JPA experts need. What I would like is my original object to have both a string object and be able to join on the same column (ihtran) and have it as a string too, but if this isn't possible or advisable I want to hear what I should do and why. Pseudo code/English is more than fine.

  • Doing a roll-in/roll-out slideshow in jQuery

    - by erizias
    I am trying to create a roll-in / roll-out slideshow in jQuery/JavaScript. My problem is, that it needs to be repeated. And right now when it's starting over, the pictures doesnt come from the right side anymore :( The reason for which I have created the slideLeft function, is that afterwards I need to create 2 functions, where the user can interrupt the slideshow manually pressing a left or right button. This is what I've got: <script class="jsbin" src="http://code.jquery.com/jquery-1.7.2.min.js"></script> <div style='background: #c4c4c4; border: 1px solid #7b7b7b; height: 220px; overflow: hidden; padding: 5px; position: absolute; width: 590px;'> <div id='slider-image-1' style='left: 5px; background: red; height: 216px; padding: 2px; position: absolute; top: 5px; width: 586px;'></div> <div id='slider-image-2' style='left: 600px; background: yellow; height: 216px; padding: 2px; position: absolute; top: 5px; width: 586px;'></div> <div id='slider-image-3' style='left: 600px; background: green; height: 216px; padding: 2px; position: absolute; top: 5px; width: 586px;'></div> <div id='slider-image-4' style='left: 600px; background: blue; height: 216px; padding: 2px; position: absolute; top: 5px; width: 586px;'></div> </div> <script type='text/javascript'> $(document).ready(function() { var amount = 0; var nextamount = 1; setInterval(function() { amount++; nextamount++; if (nextamount === 5) nextamount = 1; if (amount === 5) amount = 1; slideLeft(amount, nextamount); }, 2000); }); function slideLeft(i, j) { var $theItem = $('#slider-image-' + i); $theItem.animate({ left: parseInt($theItem.css('left'), 10) == 5 ? -$theItem.outerWidth() : 5 }, 500); var $theItem = $('#slider-image-' + j); $theItem.animate({ left: parseInt($theItem.css('left'), 10) == 5 ? $theItem.outerWidth() + 10 : 5 }, 500); }; </script>

  • Converting switch statements to more elegant solution.

    - by masfenix
    I have a 9 x 9 matrix. (think of suduko). 4 2 1 6 8 1 8 5 8 3 1 5 8 1 1 7 5 8 1 1 4 0 5 6 7 0 4 6 2 5 5 4 4 8 1 2 6 8 8 2 8 1 6 3 5 8 4 2 6 4 7 4 1 1 1 3 5 3 8 8 5 2 2 2 6 6 0 8 8 8 0 6 8 7 2 3 3 1 1 7 4 now I wanna be able to get a "quadrant". for example (according to my code) the quadrant 2 , 2 returns the following: 5 4 4 2 8 1 6 4 7 If you've noticed, this is the matrix from the very center of the 9 x 9. I've split everything up in to pairs of "3" if you know what i mean. the first "ROW" is from 0 - 3, the second from 3 - 6, the third for 6 - 9.. I hope this makes sense ( I am open to alternate ways to go about this) anyways, heres my code. I dont really like this way, even though it works. I do want speed though beccause i am making a suduko solver. //a quadrant returns the mini 3 x 3 //row 1 has three quads,"1", "2", 3" //row 2 has three quads "1", "2", "3" etc public int[,] GetQuadrant(int rnum, int qnum) { int[,] returnMatrix = new int[3, 3]; int colBegin, colEnd, rowBegin, rowEnd, row, column; //this is so we can keep track of the new matrix row = 0; column = 0; switch (qnum) { case 1: colBegin = 0; colEnd = 3; break; case 2: colBegin = 3; colEnd = 6; break; case 3: colBegin = 6; colEnd = 9; break; default: colBegin = 0; colEnd = 0; break; } switch (rnum) { case 1: rowBegin = 0; rowEnd = 3; break; case 2: rowBegin = 3; rowEnd = 6; break; case 3: rowBegin = 6; rowEnd = 9; break; default: rowBegin = 0; rowEnd = 0; break; } for (int i = rowBegin ; i < rowEnd; i++) { for (int j = colBegin; j < colEnd; j++) { returnMatrix[row, column] = _matrix[i, j]; column++; } column = 0; row++; } return returnMatrix; }

  • Sending Javascript variables.

    - by shinjuo
    I have a page that allows a user to choose some things in a form and it will calculate the weight using javascript. It breaks it up into 5 variables that I need to send to another page. Originally I was just having it put the variable into a text box and then I was posting that text box. However I dont want to have 5 text boxes. So now I need to somehow send or post the five variables to another page. Here is my javascript function. I need to post weightBoxOne - weightBoxFive js function function getWeight(){ var weightBoxOne; var weightBoxTwo; var totalWeight; var box = .5; var quantity = document.dhform.quantity.value; var cardSize = document.dhform.cardSize.value; if(cardSize == 0.0141){ if(quantity <= 1000){ weightBoxOne = (quantity * cardSize) + box; totalWeight = weightBoxOne; }else if(quantity > 1000 && quantity <= 2000){ weightBoxOne = (1000 * cardSize) + box; weightBoxTwo = ((quantity - 1000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo; }else if(quantity > 2000 && quantity <= 3000){ weightBoxOne = (1000 * cardSize) + box; weightBoxTwo = (1000 * cardSize) + box; weightBoxThree = ((quantity - 2000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo + weightBoxThree; }else if(quantity > 3000 && quantity <= 4000){ weightBoxOne = (1000 * cardSize) + box; weightBoxTwo = (1000 * cardSize) + box; weightBoxThree = (1000 * cardSize) + box; weightBoxFour = ((quantity - 3000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo + weightBoxThree + weightBoxFour; }else{ weightBoxOne = (1000 * cardSize) + box; weightBoxTwo = (1000 * cardSize) + box; weightBoxThree = (1000 * cardSize) + box; weightBoxFour = (1000 * cardSize) + box; weightBoxFive = ((quantity - 4000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo + weightBoxThree + weightBoxFour + weightBoxFive; } }else if(cardSize == 0.00949){ if(quantity <= 4000){ weightBoxOne = (quantity * cardSize) + box; totalWeight = weightBoxOne; }else{ weightBoxOne = (4000 * cardSize) + box; weightBoxTwo = ((quantity - 4000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo; } } document.rates.weight.value = totalWeight; } //--> this is the form that was originally posting <form action="getRates.php" name="rates" method="post" onSubmit="popupform(this, 'join')"> <table style="width: 216px"> <tr> <td style="width: 115px; height: 49px;"><span class="style16">Weight</span><br/> <input type="text" id="weight" name="weight" size="10" maxlength="4"/> </td> <td align="right" style="width: 68px; height: 49px;" valign="top"><span class="style16">Zip Code</span><br/> <input type="text" id="zip" name="zip" size="10" maxlength="5"/> </td> </tr> <tr> <td style="width: 115px"> <input name="submit" type="submit" value="Get Rate Costs" style="width: 138px" />

  • jquery mouse events masked by img in IE8 - all other platforms/browsers work fine

    - by Bruce
    Using the jQuery mouse events for mouseenter, mouseleave or hover all work swimmingly on all Mac or Windows browsers except for IE8/Windows. I am using mouseenter and mouseleave to test for hot rectangles (absolutely positioned and dimensioned divs that have no content) over an image used as hotspots to make visible the navigation buttons when different regions of the main enclosing rectangle (image) are touched by the cursor. Windows/IE jQuery never sends notifications (mouseenter our mouseleave) as the cursor enters or exits one of the target divs. If I turn off the visibility of the image everything works as expected (like it does in every other browser), so the image is effectively blocking all messages (the intention was for the image to be a background and all the divs float above it, where they can be clicked on). I understand that there's a z-index gotcha (so explicitly specifying z-index for each absolute positioned div does not work), but unclear as to how to nest or order multiple divs to allow a single set of jQuery rules to support all browsers. The image tag seems to trump all other divs and always appear in front of them... BTW: I could not use i m g as a tag in this text so it is spelled image in the following, so the input editor does not think that I am trying to pull a fast one on stackoverflow... How used? "mainview" is the background image, "zoneleft" and "zoneright" are the active areas where when the cursor enters the nav buttons "leftarrow" and rightarrow" are supposed to appear. Javascript $("div#zoneleft").bind("mouseenter",function () // enters left zone see left arrow { arrowVisibility("left"); document.getElementById("leftarrow").style.display="block"; }).bind("mouseleave",function () { document.getElementById("leftarrow").style.visibility="hidden"; document.getElementById("rightarrow").style.visibility="hidden"; }); HTML <div id="zoneleft" style="position:absolute; top:44px; left:0px; width:355px; height:372px; z-index:40;"> <div id="leftarrow" style="position:absolute; top:158px; left:0px; z-index:50;"><img src="images/newleft.png" width="59" height="56"/></div></div> <div id="zoneright" style="position:absolute; top:44px; left:355px; width:355px; height:372px; z-index:40;"> <div id="rightarrow" style="position:absolute; top:158px; left:296px; z-index:50;"> (tag named changed so that I could include it here) <image src="images/newright.png" width="59" height="56" /></div></div> </div><!-- navbuttons --> <image id="mainview" style="z-index:-1;" src="images/projectPhotos/photo1.jpg" width:710px; height:372px; /> (tag named changed so that I could include it here) </div><!--photo-->

  • Having trouble storing a CRTP based class in a vector

    - by user366834
    Hi, Im not sure if this can be done, im just delving into templates so perhaps my understanding is a bit wrong. I have a Platoon of soldiers, the platoon inherits from a formation to pick up the formations properties, but because i could have as many formations as i can think of I chose to use the CRTP to create the formations, hoping that i could make a vector or array of Platoon to store the platoons in. but, of course, when i make a Platoon, it wont store it in the vector, "types are unrelated" Is there any way around this ? i read about "Veneers" which are similar and that they work with arrays but i cant get it to work, perhaps im missing something. here's some code: (sorry about the formatting, the code is here in my post but its not showing up for some reason ) template < class TBase > class IFormation { public : ~IFormation(){} bool IsFull() { return m_uiMaxMembers == m_uiCurrentMemCount; } protected: unsigned int m_uiCurrentMemCount; unsigned int m_uiMaxMembers; IFormation( unsigned int _uiMaxMembers ): m_uiMaxMembers( _uiMaxMembers ), m_uiCurrentMemCount( 0 ){} // only allow use as a base class. void SetupFormation( std::vector<MySoldier*>& _soldierList ){}; // must be implemented in derived class }; ///////////////////////////////////////////////////////////////////////////////// // PHALANX FORMATION class Phalanx : public IFormation<Phalanx> { public: Phalanx( ): IFormation( 12 ), m_fDistance( 4.0f ) {} ~Phalanx(){} protected: float m_fDistance; // the distance between soldiers void SetupFormation( std::vector<MySoldier*>& _soldierList ); }; /////////////////////////////////////////////////////////////////////////////////// // COLUMN FORMATINO class Column : public IFormation< Column > { public : Column( int _numOfMembers ): IFormation( _numOfMembers ) {} ~Column(); protected: void SetupFormation( std::vector<MySoldier*>& _soldierList ); }; I then use these formations in the platoon class to derive, so that platoon gets the relevant SetupFormation() function: template < class Formation > class Platoon : public Formation { public: **** platoon code here }; everything works great and as expected up until this point. now, as my general can have multiple platoons, I need to store the platoons. typedef Platoon< IFormation<> > TPlatoon; // FAIL typedef std::vector<TPlatoon*> TPlatoons; TPlatoon m_pPlatoons m_pPlatoons.push_back( new Platoon<Phalanx> ); // FAIL, types unrelated. typedef Platoon< IFormation< TPlatoon; fails because i need to specify a template parameter, yet specifying this will only allow me to store platoons created with the same template parameter. so i then created FormationBase class FormationBase { public: virtual bool IsFull() = 0; virtual void SetupFormation( std::vector<MySoldier*>& _soldierList ) = 0; }; and made IFormation publicly inherit from that, and then changed the typedef to typedef Platoon< IFormation< FormationBase > > TPlatoon; but still no love. now in my searches i have not found info that says this is possible - or not possible.

  • Problem with Global Array in PHP

    - by Suezy
    Hi guys,, need some help pls.. i have a PHP code here that lets a user send a message to multiple recipients using the "phonebook" (from database) as the main list. I used an array to temporarily hold all the desired recipients for the current user. So I have a two box, with each for displaying. The user will clicks the name from the phonebook lisy and clicks "Add" button to add on the temporary list on the other select box. The problem is, whenever I use the "onChange" function in javascript; the array accepts only one recipients, and when I try to add, it replaces the first one. :( Here is my code: $recipients = array(); // How do I place the array here? function reload_page(){ i=document.maillinglist.firstletter.selectedIndex; this.location='./group_msg.php?firstletter='+document.maillinglist.firstletter.options[i].value; } function add(){ } $conn = pg_connect("host=localhost user=sa dbname=messaging"); if(isset($_GET['firstletter'])){ $letter=$_GET['firstletter']; } else { $letter='a';} print ""; print "GROUP MESSAGE"; print ""; print ""; print ""; print ""; for($chr_loop=97;$chr_loop<=122;$chr_loop++){ $alphabet = chr($chr_loop); # Displays list of users arranged by letters - this works fine if($alphabet==$letter){ print "\t\t<option value='$alphabet' selected>-------------------- $alphabet --------------------</option>\n"; } else { print "\t\t<option value='$alphabet'>-------------------- $alphabet --------------------</option>\n";} } print ""; print "<td><select style='width:210px' name=\"non_members[]\" size=10 width=200>"; $sql = "select name from test_phonebook where name like '$letter%';"; $result = pg_query($conn, $sql); # Display users from phonebook using the letter chosen while($row = pg_fetch_assoc($result)){ $my_name = $row['name']; print "<option width=200 value=\"$my_name\">$my_name</option>"; } print "</td>"; print "</select>"; print "<td><input type=submit name=add value=\"->>\" onClick=\"add()\"><br><input type=submit name=del value=\"<<-\"></td>"; print "<td><select name=\"members[]\" style='width:210px' size=10>"; # Display temporary recipients - problem: ONLY DISPLAYS ONE VALUE while (list ($key, $val) = each ($recipients)) { echo "$key -> $val <br>"; print "<option width=200 value=\"$val\">$val</option>"; } print "</select></table></form>"; My aim here, is to place all recipients that the user desires to an array, without losing the previous value added.

    Here's the picture to begin with. I have this check box, that when you check, then with jQuery toggle(); it hides that you see in first half of the picture (#writeComment) and shows #SCtryVOTE (what you see in the other half picture, to the right). Now i dont know why but of some reason it expands when its checked, why i dont know, is it because it needs more place than it have or? how do i make this work without having problems when its checked. Here's coding: $('#tryout').click(function () { $('#writeComment').toggle(!$(this).attr('checked')); $('#SCtryVOTE').toggle($(this).attr('checked')); }); the js jquery script part, heres the table and divs HTML part: <input type="checkbox" id="tryout"> <table align="center" width="400" cellpadding="0" cellspacing="1" id="theBoxer"> <tr style="background: #686868;"> <td align="center" valign="top" width="70" height="25" style="border:1px #FFF solid;">Opret</td> <td align="center" valign="top" width="70" height="25" style="border:1px #FFF solid;">Opret</td> </td> </tr> <tr> <td align="left" valign="top" width="70" height="112" style=""> TEST </td> <td align="left" valign="top" width="70" height="112" style=""> <div id="writeComment"> Smid en kommentar:<br> <form action="javascript:DoInsert()" method="post"> <textarea id="kommentar" name="kommentar"></textarea><br /> <input type="hidden" name="fID" id="fID" value="<? echo $_GET["id"]; ?>"> <input type="submit" name="Submit" value="Sæt ind!"> </form> </div> <div id="SCtryVOTE" style="display: none;"> <form onsubmit="if (!this.comment.cleared) clearContents( document.getElementById('comment') ); return true;" action="javascript:DoSCInsert()" method="post"> <textarea onfocus=" javascript:clearContents(this); this.cleared=true;" rows="5" cols="40" id="comment" name="comment" <?php if($vis["username"] == $pusername) { echo "DISABLED"; } ?>>Tryk for at skrive.

    I'm trying to implement line thickness as denoted here: start = line start = vector(x1, y1) end = line end = vector(x2, y2) dir = line direction = end - start = vector(x2-x1, y2-y1) ndir = normalized direction = dir*1.0/length(dir) perp = perpendicular to direction = vector(dir.x, -dir.y) nperp = normalized perpendicular = perp*1.0/length(perp) perpoffset = nperp*w*0.5 diroffset = ndir*w*0.5 p0, p1, p2, p3 = polygon points: p0 = start + perpoffset - diroffset p1 = start - perpoffset - diroffset p2 = end + perpoffset + diroffset p3 = end - perpoffset + diroffset I'v implemented this like so: void OGLENGINEFUNCTIONS::GenerateLinePoly(const std::vector<std::vector<GLdouble>> &input, std::vector<GLfloat> &output, int width) { output.clear(); float temp; float dirlen; float perplen; POINTFLOAT start; POINTFLOAT end; POINTFLOAT dir; POINTFLOAT ndir; POINTFLOAT perp; POINTFLOAT nperp; POINTFLOAT perpoffset; POINTFLOAT diroffset; POINTFLOAT p0, p1, p2, p3; for(int i = 0; i < input.size() - 1; ++i) { start.x = input[i][0]; start.y = input[i][1]; end.x = input[i + 1][0]; end.y = input[i + 1][1]; dir.x = end.x - start.x; dir.y = end.y - start.y; dirlen = sqrt((dir.x * dir.x) + (dir.y * dir.y)); ndir.x = dir.x * (1.0 / dirlen); ndir.y = dir.y * (1.0 / dirlen); perp.x = dir.x; perp.y = -dir.y; perplen = sqrt((perp.x * perp.x) + (perp.y * perp.y)); nperp.x = perp.x * (1.0 / perplen); nperp.y = perp.y * (1.0 / perplen); perpoffset.x = nperp.x * width * 0.5; perpoffset.y = nperp.y * width * 0.5; diroffset.x = ndir.x * width * 0.5; diroffset.y = ndir.x * width * 0.5; // p0 = start + perpoffset - diroffset //p1 = start - perpoffset - diroffset //p2 = end + perpoffset + diroffset // p3 = end - perpoffset + diroffset p0.x = start.x + perpoffset.x - diroffset.x; p0.y = start.y + perpoffset.y - diroffset.y; p1.x = start.x - perpoffset.x - diroffset.x; p1.y = start.y - perpoffset.y - diroffset.y; p2.x = end.x + perpoffset.x + diroffset.x; p2.y = end.y + perpoffset.y + diroffset.y; p3.x = end.x - perpoffset.x + diroffset.x; p3.y = end.y - perpoffset.y + diroffset.y; output.push_back(p0.x); output.push_back(p0.y); output.push_back(p1.x); output.push_back(p1.y); output.push_back(p2.x); output.push_back(p2.y); output.push_back(p3.x); output.push_back(p3.y); } } But right now the lines look perpendicular and wrong, it should be giving me quads to render which is what i'm rendering, but the points it is outputing are strange. Have I done this wrong? Thanks

  • C# slowdown while creating a bitmap - calculating distances from a large List of places for each pixel

    - by user576849
    I'm creating a graphic of the glow of lights above a geographic location based upon Walkers Law: Skyglow=0.01*Population*DistanceFromCenter^-2.5 I have a CSV file of places with 66,000 records using 5 fields (id,name,population,latitude,longitude), parsed on the FormLoad event and stored it in: List<string[]> placeDataList Then I set up nested loops to fill in a bitmap using SetPixel. For each pixel on the bitmap, which represents a coordinate on a map (latitude and longitude), the program loops through placeDataList – calculating the distance from that coordinate (pixel) to each place record. The distance (along with population) is used in a calculation to find how much cumulative sky glow is contributed to the coordinate from each place record. So, for every pixel, 66,000 distance calculations must be made. The problem is, this is predictably EXTREMELY slow – on the order of one line of pixels per 30 seconds or so on a 320 pixel wide image. This is unrelated to SetPixel, which I know is also slow, because the speed is similarly slow when adding the distance calculation results to an array. I don’t actually need to test all 66,000 records for every pixel, only the records within 150 miles (i.e. no skyglow is contributed to a coordinate from a small town 3000 miles away). But to find which records are within 150 miles of my coordinate I would still need to loop through all the records for each pixel. I can't use a smaller number of records because all 66,000 places contribute to skyglow for SOME coordinate in my map as it loops. This seems like a Catch-22, so I know there must be a better method out there. Like I mentioned, the slowdown is related to how many calculations I’m making per pixel, not anything to do with the bitmap. Any suggestions? private void fillPixels(int width) { Color pixelColor; int pixel_w = width; int pixel_h = (int)Math.Floor((width * 0.424088664)); Bitmap bmp = new Bitmap(pixel_w, pixel_h); for (int i = 0; i < pixel_h; i++) for (int j = 0; j < pixel_w; j++) { pixelColor = getPixelColor(i, j); bmp.SetPixel(j, i, pixelColor); } bmp.Save("Nightfall", System.Drawing.Imaging.ImageFormat.Jpeg); pictureBox1.Image = bmp; MessageBox.Show("Done"); } private Color getPixelColor(int height, int width) { int c; double glow,d,cityLat,cityLon,cityPop; double testLat, testLon; int size_h = (int)Math.Floor((size_w * 0.424088664)); ; testLat = (height * (24.443136 / size_h)) + 24.548874; testLon = (width * (57.636853 / size_w)) -124.640767; glow = 0; for (int i = 0; i < placeDataList.Count; i++) { cityPop=Convert.ToDouble(placeDataList[i][2]); cityLat=Convert.ToDouble(placeDataList[i][3]); cityLon=Convert.ToDouble(placeDataList[i][4]); d = distance(testLat, testLon, cityLat, cityLon,"M"); if(d<150) glow = glow+(0.01 * cityPop * Math.Pow(d, -2.5)); } if (glow >= 1) glow=1; c = (int)Math.Ceiling(glow * 255); return Color.FromArgb(c, c, c); }

    Here is my website without any CSS: http://www.wmcicompsci.ca/cs20/students/theglowcloud/Bare%20bones%20website/classics_bare.html I am new to CSS and I would like to organize pictures these pictures in this fashion: http://css-tricks.com/examples/SlideinCaptions/ I would just like this layout for the pictures but I do not need the sliding of the captions(although I would like to but it does not work my browser). I would like the captions to be like titles on top of the pictures. Here is my current html code: <!DOCTYPE html> <html> <head> <title> My favourite Fantasy books</title> <meta charset = "utf-8"> <link rel="stylesheet" href="css.css"> </head> <body> <nav id="main_nav"> <ul> <li><a href = " homepage_css.html"> Homepage</a></li> <li><a href="science_fiction_css.html">Science Fiction</a></li> <li><a href="classics_css.html">Classics</a></li> <li><a href="fantasy_css.html">Fantasy</a></li> </ul> </nav> <h1> Fantasy Genre</h1> <p> Here are my favourites:</p> <ul> <li> Goblet of Fire by J.K Rowling (4th book in the Harry Potter Series) </li> <li><img class= displayed src="pics/fantasy/goblet_of_fire.jpg" width="200" alt="Goblet of Fire book cover"></li> <li> Graceling by Kristan Cashore </li> <li><img src="pics/fantasy/graceling.jpg" width="200" alt = " Graceling book cover"></li> <li> Serpent's Shadow by Rick Riordan (3rd book in the Kane Chronicles) </li> <li><img src="pics/fantasy/serpents_shadow.jpg" width="200" alt="Serpent's Shadow book cover"></li> <li> The Hobbit by J.R.R.

  • jQuery embedding youtube IE issue

    - by webmonkey237
    I have been working on a custom image slider featured here: JQuery $(function(){ $('.cont:gt(0)').hide(); $("#parent").on("mouseenter", ".extraContent div", function(){ var ind = $(this).index(); $("#parent").find(".cont").stop().fadeTo(600,0,function(){ $('#parent').find('.cont').eq(ind).stop().fadeTo(300,1); }); }); $('#parent .extraContent').on('click',function(){ window.location=$(this).find("a").attr("href"); return false; }); }); CSS ?#parent { width:400px; margin:auto} .mainContent { width:430px; height:300px; border:1px solid #000;padding:5px; } .extraContent {overflow:auto; width:450px;} .extraContent div{float:left; width:90px; height:90px; border:1px solid #00F; margin:5px; padding:5px } .extraContent div:hover { border:1px solid #0F0;cursor:pointer } .cont{ position:absolute; } HTML <div id="parent"> <div class="mainContent"> <div class="cont"> Content 1....</div> <div class="cont"> Content 2....</div> <div class="cont">Content 3...<br /><iframe width="267" height="200" src="http://www.youtube.com/embed/6tlQn7iePV4?rel=0" frameborder="0" allowfullscreen></iframe></div> <div class="cont"> Content 4....</div> </div> <div class="extraContent"> <div><p>1 Custom content here <br /> <a href="">Some link</a></p></div> <div><p>2 Custom content here <br /> <a href="">Some link</a></p></div> <div><p>3 Custom content here <br /> <a href="">Some link</a></p></div> <div><p>4 Custom content here <br /> <a href="">Some link</a></p></div> </div> </div>? My problem is if I embed YouTube video straight from the site using there iframe it transitions fine in Chrome but Firefox & IE just display the video straight away and each slide/div appears under the video, is this a known problem and doesn't anyone know a way I can get IE & FF to behave. p.s. because this is going to be in a content management system the only way the user can embed the video is using the default code from youtube.

  • jQuery - Stucked Animation

    - by v1n_vampire
    I'm kind of tired with Javascript long script for animation and decide to try jQuery, but it seems I'm stuck even at the simplest code. CSS: #menu {float: right; font: italic 16px/16px Verdana, Geneva, sans-serif;} ul#nav {list-style: none;} ul#nav li {float: left; padding-right: 10px;} ul#nav li a {color: white;} ul#subnav {float: right; list-style: none; padding: 0; display: none;} ul#subnav li {float: left; padding: 10px 5px; white-space: nowrap;} ul#subnav li a {color: white;} Script: $(document).ready(function() { $('.nav').hover(function() { $(this).find('#subnav').stop().animate({width:'toggle'},350); }); }); HTML: <div id="menu"> <ul id="nav"> <li class="nav"> <a href="#"><img src="images/icon-home.png" width="36" height="36"/></a> <ul id="subnav"> <li><a href="#">Home</a></li> </ul> </li> <li class="nav"> <a href="#"><img src="images/icon-signin.png" width="36" height="36"/></a> <ul id="subnav"> <li><a href="#">Sign In</a></li> </ul> </li> <li class="nav"> <a href="#"><img src="images/icon-register.png" width="36" height="36"/></a> <ul id="subnav"> <li><a href="#">Create Account</a></li> </ul> </li> <li class="nav" style="padding-right: 0;"> <a href="#"><img src="images/icon-mail.png" width="36" height="36"/></a> <ul id="subnav"> <li style="padding-right: 0;"><a href="#">Contact Us</a></li> </ul> </li> </ul> </div> Here's the sample page: http://v1n-vampire.com/dev/jq-animation-stuck If you continue to hover on the nav from left to right then back to left, eventually the animation will stuck. How to solve this? Thank you in advance.
