  • Tabular (X)HTML forms

    - by detly
    I have a set of items that can be in various states. I want to allow a user to use an (X)HTML form to change the state, and easily view the state of a group of objects ...so to this end, I'd like a layout like: | item1 | radio button for state 1 | radio for state 2 | ... | [update button] | | item2 | radio button for state 1 | radio for state 2 | ... | [update button] | etc. I prefer the radio buttons to list boxes so that it's easy for a user to visually scan for things in a certain state. It seemed like perfectly tabular data to me. The only problem is, you can't have forms inside a table that cross table cells (ie. <tr> <form> <td> ... is invalid). I thought, "hey, I could have one giant form wrapping a table, and make the [update button] value contain the IDs for each row!" Turns out certain versions of IE send ALL THE SUBMIT BUTTON VALUES on any single form. So I thought perhaps to to lay it out with <div>s and place the forms inside a single <td>. But then they break a line on each <div>. So I fixed their width and made them float: left. But then they wrap inside the table cells if the table row is wider than the page, and the radio controls don't line up with the headings. Is it possible to lay this out as I intend? The XHTML below shows the intended structure. Observe what happens if you resize the browser window below the width of the table (ideally, the name would break or the table would show a scroll bar). <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head><title>Test</title> <style type="text/css"> .state-select, .thing-state-name, .update { float: left; width: 8em; } .state-select { text-align: center; } </style> </head> <body> <table> <thead> <tr> <th class="thing-name-header">Thing</th> <th> <div class="thing-state-name">Present</div> <div class="thing-state-name">Absent</div> <div class="thing-state-name">Haven't looked</div> </th> </tr> </thead> <tbody> <tr> <td>Apple</td> <td> <form action="something" method="post"> <input type="hidden" name="id" value="1" /> <div class="state-select"><input type="radio" name="presence" value="present" checked="checked" /></div> <div class="state-select"><input type="radio" name="presence" value="absent" /></div> <div class="state-select"><input type="radio" name="presence" value="unknown" /></div> <div class="update"><input type="submit" value="Update" /></div> </form> </td></tr> <tr> <td>Orange</td> <td> <form action="something" method="post"> <input type="hidden" name="id" value="2" /> <div class="state-select"><input type="radio" name="presence" value="present" /></div> <div class="state-select"><input type="radio" name="presence" value="absent" checked="checked" /></div> <div class="state-select"><input type="radio" name="presence" value="unknown" /></div> <div class="update"><input type="submit" value="Update" /></div> </form> </td></tr> <tr> <td>David Bowie</td> <td> <form action="something" method="post"> <input type="hidden" name="id" value="3" /> <div class="state-select"><input type="radio" name="presence" value="present" /></div> <div class="state-select"><input type="radio" name="presence" value="absent" /></div> <div class="state-select"><input type="radio" name="presence" value="unknown" checked="checked" /></div> <div class="update"><input type="submit" value="Update" /></div> </form> </td></tr> </tbody> </table> </body> </html>

  • How do I.. get a value for time at 9:00am local, regardless of the timezone?

    - by ander163
    In my app, I need to set a variable for a start time to be 9:00 a.m. local, wherever the user is located. I have a timezone variable for each user and the save and retrieve are all working. But I need to set a variable when I create a new event to be 9:00 am in the user's local time zone. My current method uses the local time of the server, then makes the adjustments for the individual user's time zone. I don't know what I don't know - is there a command to create the value for "Today's date at 9:00 am where you are"? My current code is: t = Time.now.to_date.beginning_of_day + 11.hours (forcing the 2 hour offset between my primary user and the server in a different timezone).

  • Alpha Beta Search

    - by Becky
    I'm making a version of Martian Chess in java with AI and so far I THINK my move searching is semi-working, it seems to work alright for some depths but if I use a depth of 3 it returns a move for the opposite side...now the game is a bit weird because when a piece crosses half of the board, it becomes property of the other player so I think this is part of the problem. I'd be really greatful if someone could look over my code and point out any errors you think are there! (pls note that my evaluation function isn't nearly complete lol) MoveSearch.java public class MoveSearch { private Evaluation evaluate = new Evaluation(); private int blackPlayerScore, whitePlayerScore; public MoveContent bestMove; public MoveSearch(int blackScore, int whiteScore) { blackPlayerScore = blackScore; whitePlayerScore = whiteScore; } private Vector<Position> EvaluateMoves(Board board) { Vector<Position> positions = new Vector<Position>();

  • Does a nested subTable break reRender?

    - by Tom
    Here is a minimal rich:dataTable with an a4j:commandLink inside. When clicked it sends an AJAX request to my bean and reRenders the dataTable. <rich:dataTable id="dataTable" value="#{carManager.all}" var="item"> <rich:column> <f:facet name="header">name</f:facet> <h:outputText value="#{item.name}" /> </rich:column> <rich:column> <f:facet name="header">action</f:facet> <a4j:commandLink reRender="dataTable" value="Delete" action="#{carForm.delete}"> <f:setPropertyActionListener value="#{item.id}" target="#{carForm.id}" /> <f:param name="from" value="list" /> </a4j:commandLink> </rich:column> </rich:dataTable> The exmaple obove works fine so far. But when I add a rich:subTable to the table, reRendering fails... <rich:dataTable id="dataTable" value="#{garageManager.all}" var="garage"> <f:facet name="header"> <rich:columnGroup> <rich:column>name</rich:column> <rich:column>action</rich:column> </rich:columnGroup> </f:facet> <rich:column colspan="2"> <h:outputText value="#{garage.name}" /> </rich:column> <rich:subTable value="#{garage.cars}" var="car"> <rich:column><h:ouputText value="#{car.name}" /></rich:column> <rich:column> <a4j:commandLink reRender="dataTable" value="Delete" action="#{carForm.delete}"> <f:setPropertyActionListener value="#{item.id}" target="#{carForm.id}" /> <f:param name="from" value="list" /> </a4j:commandLink> </rich:column> </rich:column> </rich:dataTable> Now the rich:dataTable is not rerendered but the item gets deleted since the item does not show up after a complete page refresh. Why does subTable break support for reRender-ing the way i'd like to use it here? Tanks Tom

  • Create a string with the result of an expression and the expression that originated the value. Is it

    - by Oscar Reyes
    Like String r = SomeThing.toExecString("new Object().toString()"); And when executed the value of r would be: "new Object().toString() = java.lang.Object@c5e3974" Is this even possible at all? Would it need a bunch of reflection? A built in compiler maybe? AFAIK, this is not possible with regular Java. The closest thing I could get is IDE support like in IDEA with the "macro" soutv+tab that prints: Hit taband type the expression The IDE types the rest for you. But that's quite another completely thing.

  • Convert methods from Java-actionscript to ObjectiveC

    - by eco_bach
    Hi I'm tring to convert the following 3 methods from java-actionscript to Objective C. Part of my confusion I think is not knowing what Number types, primitives I should be using. ie in actionscript you have only Number, int, and uint. These are the 3 functions I am trying to convert public function normalize(value:Number, minimum:Number, maximum:Number):Number { return (value - minimum) / (maximum - minimum); } public function interpolate(normValue:Number, minimum:Number, maximum:Number):Number { return minimum + (maximum - minimum) * normValue; } public function map(value:Number, min1:Number, max1:Number, min2:Number, max2:Number):Number { return interpolate( normalize(value, min1, max1), min2, max2); } This is what I have so far -(float) normalize:(float*)value withMinimumValue:(float*)minimum withMaximumValue:(float*)maximum { return (value - minimum) / (maximum - minimum); } -(float) interpolate:(float*)normValue withMinimumValue:(float*)minimum withMaximumValue:(float*)maximum { return minimum + (maximum - minimum) * normValue; } -(float) map:(float*)value withMinimumValue1:(float*)min1 withMaximumValue1:(float*)max1 withMinimumValue2:(float*)min2 withMaximumValue2:(float*)max2 { return interpolate( normalize(value, min1, max1), min2, max2); }

  • SQL: How do I return zeroes where there is nothing to aggregate across?

    - by Karl
    Hi What I would like ask is best illustrated by an example, so bear with me. Suppose I have the following table: TypeID Gender Count 1 M 10 1 F 3 1 F 6 3 M 11 3 M 8 I would like to aggregate this for every possible combination of TypeID and Gender. Where TypeID can be 1,2 or 3 and Gender can be M or F. So what I want is the following: TypeID Gender SUM(Count) 1 M 10 1 F 9 2 M 0 2 F 0 3 M 19 3 F 0 I can think of a few ways to potentially do this, but none of them seem particularly elegant to me. Any suggestions would be greatly appreciated! Karl

  • When anyDensity=false why does getDrawingCache(true) return null?

    - by Robert Nekic
    First off, my application currently defines anyDensity=false in the manifest file. Elsewhere in the app, I'm trying to capture and display a View's DrawingCache but I'm not able to get a clear Bitmap without scaling artifacts. The code below yields a Bitmap but it has scaling artifacts and is generally fuzzy. myView.setDrawingCacheEnabled(true); Bitmap myBitmap = Bitmap.Create(myView.getDrawingCache()); myImageView.setImageBitmap(myBitmap); As I read it, the documentation for getDrawingCache says this is to be expected and to use getDrawingCache(true). Yet, both code examples below throw NullPointer exceptions because the Bitmap returned by getDrawingCache(true) is always null. myView.setDrawingCacheEnabled(true); Bitmap myBitmap = Bitmap.Create(myView.getDrawingCache(true)); myImageView.setImageBitmap(myBitmap); OR myView.buildDrawingCache(true); Bitmap myBitmap = Bitmap.Create(myView.getDrawingCache(true)); myImageView.setImageBitmap(myBitmap); myView.destroyDrawingCache(); Does anyone know how to properly capture and render the drawingCache when anyDensity=false?

  • Empty accessors do matter? Regarding value types and their modification

    - by Petr
    Hi, I have following code that does not work due to "a" being a value typed. But I thought it would not work even without accessors, but it did: class Program { a _a //with accessors it WONT compile { get; set; } static void Main(string[] args) { Program p = new Program(); p._a.X = 5; //when both accessors are deleted, compiler does not //complain about _a.X not being as variable } } struct a { public int X; } It does not work as "a" is struct. But when I delete accessors from "_a" instance, it works. I do not understand why. Thanks

  • How to I create an HQL query to return objects in a many to many relationship?

    - by Dave
    Hi there. I have an application that includes 2 classes Club and Article. These are mapped in Hibernate as a many to many relationship. As a result, hibernate has created a table called CLUB_ARTICLE which it uses to manage the many to many relation ship. The CLUB and ARTILCE tables have no direct reference to each other and the mapping is only represented in the CLUB_ARTICLE table. I need to create an HQL query that returns a list of articles for a particlular club. So I need to supply the club id and get back a list of Article objects that belong to it. For some reason, I just can't work out how to do this. Any help would be very much appriciated! Thanks.

  • How do You Get a Specific Value From a System.Data.DataTable Object?

    - by Giffyguy
    I'm a low-level algorithm programmer, and databases are not really my thing - so this'll be a n00b question if ever there was one. I'm running a simple SELECT query through our development team's DAO. The DAO returns a System.Data.DataTable object containing the results of the query. This is all working fine so far. The problem I have run into now: I need to pull a value out of one of the fields of the first row in the resulting DataTable - and I have no idea where to even start. Microsoft is so confusing about this! Arrrg! Any advice would be appreciated. I'm not providing any code samples, because I believe that context is unnecessary here. I'm assuming that all DataTable objects work the same way, no matter how you run your queries - and therefore any additional information would just make this more confusing for everyone.

  • storing session data in mysql using php is not retrieving the data properly from the tables.

    - by Ronedog
    I have a problem retrieving some data from the $_SESSION using php and mysql. I've commented out the line in php.ini that tells the server to use the "file" to store the session info so my database will be used. I have a class that I use to write the information to the database and its working fine. When the user passes their credentials the class gets instantiated and the $_SESSION vars get set, then the user gets redirected to the index page. The index.php page includes the file where the db session class is, which when instantiated calles session_start() and the session variables should be in $_SESSION, but when I do var_dump($_SESSION) there is nothing in the array. However, when I look at the data in mysql, all the session information is in there. Its acting like session_start() has not been called, but by instantiating the class it is. Any idea what could be wrong? Here's the HTML: <?php include_once "classes/phpsessions_db/class.dbsession.php"; //used for sessions var_dump($_SESSION); ?> <html> . . . </html> Here's the dbsession class: <?php error_reporting(E_ALL); class dbSession { function dbSession($gc_maxlifetime = "", $gc_probability = "", $gc_divisor = "") { // if $gc_maxlifetime is specified and is an integer number if ($gc_maxlifetime != "" && is_integer($gc_maxlifetime)) { // set the new value @ini_set('session.gc_maxlifetime', $gc_maxlifetime); } // if $gc_probability is specified and is an integer number if ($gc_probability != "" && is_integer($gc_probability)) { // set the new value @ini_set('session.gc_probability', $gc_probability); } // if $gc_divisor is specified and is an integer number if ($gc_divisor != "" && is_integer($gc_divisor)) { // set the new value @ini_set('session.gc_divisor', $gc_divisor); } // get session lifetime $this->sessionLifetime = ini_get("session.gc_maxlifetime"); //Added by AARON. cancel the session's auto start,important, without this the session var's don't show up on next pg. session_write_close(); // register the new handler session_set_save_handler( array(&$this, 'open'), array(&$this, 'close'), array(&$this, 'read'), array(&$this, 'write'), array(&$this, 'destroy'), array(&$this, 'gc') ); register_shutdown_function('session_write_close'); // start the session @session_start(); } function stop() { $new_sess_id = $this->regenerate_id(true); session_unset(); session_destroy(); return $new_sess_id; } function regenerate_id($return_val=false) { // saves the old session's id $oldSessionID = session_id(); // regenerates the id // this function will create a new session, with a new id and containing the data from the old session // but will not delete the old session session_regenerate_id(); // because the session_regenerate_id() function does not delete the old session, // we have to delete it manually //$this->destroy($oldSessionID); //ADDED by aaron // returns the new session id if($return_val) { return session_id(); } } function open($save_path, $session_name) { // global $gf; // $gf->debug_this($gf, "GF: Opening Session"); // change the next values to match the setting of your mySQL database $mySQLHost = "localhost"; $mySQLUsername = "user"; $mySQLPassword = "pass"; $mySQLDatabase = "sessions"; $link = mysql_connect($mySQLHost, $mySQLUsername, $mySQLPassword); if (!$link) { die ("Could not connect to database!"); } $dbc = mysql_select_db($mySQLDatabase, $link); if (!$dbc) { die ("Could not select database!"); } return true; } function close() { mysql_close(); return true; } function read($session_id) { $result = @mysql_query(" SELECT session_data FROM session_data WHERE session_id = '".$session_id."'

  • Javas Math.sin() produces NaN all the time

    - by milan1612
    Forgive me if this is a dumb beginners problem, but I really don't get it. I have a member variable declared like so: public Double Value; When I assign 3.14159265 to Value and try to compute the sine of it, this happens: system.out.println(Value.toString()); //outputs 3.14159265 Value = Math.sin(Value); system.out.println(Value.toString()); //outputs NaN In fact, this happens with every single value I tried - even with 0! Math.sin() seems to always produce NaN as a result, regardless of the arguments value. The docs say: If the argument is NaN or an infinity, then the result is NaN. But my argument is clearly not NaN or infinity! What the heck is happening there?

  • How to add CSS classes to Zend_Form_Element_Select option

    - by Jah Selassie
    Hi, I'm trying to add a CSS class to a Zend_Form_Element_Select option, but I just can't find a way to do it. The desired output would be something like this: <select name="hey" id="hey"> <option value="value1" style="parent">label1</option> <option value="value2" style="sibling">sublabel1</option> <option value="value3" style="sibling">sublabel2</option> <option value="value4" style="parent">label2</option> <option value="value5" style="sibling">sublabel3</option> <option value="value6" style="sibling">sublabel4</option> </select> But I'm getting this: <select name="hey" id="hey"> <option value="value1">label1</option> <option value="value2">sublabel1</option> <option value="value3">sublabel2</option> <option value="value4">label2</option> <option value="value5">sublabel3</option> <option value="value6">sublabel4</option> </select> I can't seem to pass a CSS class attribute to any of the options in the select element although I can style the select element itselft. My code: $sel = new Zend_Form_Element_Select('hey'); $sel->setRequired(true)->setLabel('Select an Option:'); $sel->addMultiOption('value1', 'label1', array('class' => 'parent')) ->addMultiOption('value2', 'sublabel1', array('class' => 'sibling')) (etc...); After researching a bit I found out that Element_Select doesn't have a method for adding CSS styles to the options in the select box, only for the select itself. So, how can I add them? Should I extend the form_element_select? Or would a custom decorator suffice? Can anyone give me a hint? I'm baffled with this. Thanks in advance!

  • Best practice to pass a value from pop over control on iPad.

    - by Tattat
    It is an iPad app based on SDK 3.2. I have a MainUIView, that is subclass from UIView, it have a UIButton and a UILabel. When user press the UIButton, the pop over control will be appeared with a table view. When the user select a cell from the table view, the UILabel changes content base on the user click, and the pop up table view will disappear. The question is, how can I pass the "selected cell" to the UILabel. I am thinking making a "middle man" object. When the user click the UIButton, and the "middle man" will pass to the table. When the cell is selected, the "middle man" will store the idx, and call the UILabel change content from the value of "middle man". But I think it is pretty complex to implement, is there any easier way to implement it? thz u.

  • In Ruby on Rails, why will story.votes return an empty Array object, but story.votes.create will act

    - by Jian Lin
    In Ruby on Rails, say a Story object can "has_many" Vote objects (a story is voted "hot" by many users). So when we do a s = Story.find(:first) s is a Story object, and say s.votes returns [] and s.votes.class returns Array So clearly, s.votes is an empty Array object. At this time, when s.votes.create is called, it actually invokes a method of the Vote class? How come an Array class object can invoke a Vote class method?
