  • Binding a single array cell to a WPF control

    - by yomi
    Hi, I have a bool array of size 4 and I want to bind each cell to a different control. This bool array represents 4 statuses (false = failure, true = success). This bool array is a propery with a class: class foo : INotifyPropertyChanged { ... private bool[] _Statuses; public bool[] Statuses { get {return Statuses;} set { Statuses = value; OnPropertyChanged("Statuses"); } } In XAML there are 4 controls, each one bound to one cell of the array: ... Text="{Binding Path=Statuses[0]}" ... ... Text="{Binding Path=Statuses[1]}" ... ... Text="{Binding Path=Statuses[2]}" ... ... Text="{Binding Path=Statuses[3]}" ... The problem is that the notify event is raised only when I change the array itself and isn't raised when I change one value within the array, i.e, next code line raises the event: Statuses = new bool[4]; but next line does not raises the event: Statuses [0] = true; How can I raise the event each time one cell is changed?

  • c++ code cons/pros

    - by VirusEcks
    below i have a code that runs in most of my simple programs .. . i want to know if it's good/bad ... and cons/pros . . win32 header file: win32.h #include <windows.h> #include <process.h> #include <stdarg.h> main header file: inc.h #include "win32.h" #ifndef INCS #define INCS #define DD #else #define DD extern #endif #ifndef VARS #define titlen L"my program" #endif DD wchar_t gtitle[512]; DD wchar_t gclass[512]; DD wchar_t gdir[32767]; #include "resources.h" #include "commonfunctions.h" then all files have something like this commonfunctions.h DD inline bool icmp( const char *String1, const char *String2 ) { if ( _stricmp( String1, String2 ) == 0 ) { return true; } return false; } DD inline bool scmp( const char *String1, const char *String2 ) { if ( strcmp( String1, String2 ) == 0 ) { return true; } return false; } all global variables have DD infront of them and all functions have DD too . is there a bad side of this ? . i came up with this idea and it wasn't problematic at all in small programs . but before i apply it in a large project will it be problematic ?. thanks in advance.

  • jQuery - making sure content is loaded before it's faded in?

    - by Kenny Bones
    Hi, Nick Craver really helped me out alot with this code in this thread http://stackoverflow.com/questions/2743443/jquery-can-someone-help-stitching-jquery-code-with-ajaxcomplete/2743791#2743791 And it is working. But I notice that there's a small delay after I've clicked a link and before the content is actually loaded. It's not very intense content that's loaded either so I think it's got something to do with the order which things happen in the script. The original code looks like this: $('.dynload').live('click', function(){ var toLoad = $(this).attr('href')+' #content'; $('#content').fadeOut('fast',loadContent); $('#ajaxloader').fadeIn('normal'); function loadContent() { $('#content').load(toLoad,'',showNewContent()) } function showNewContent() { $('#content').fadeIn('fast',hideLoader()); //Cufon.replace('h1, h2, h3, h4, .menuwrapper', { fontFamily: 'advent'}); } function hideLoader() { $('#ajaxloader').fadeOut('normal'); } return false; }); The new code looks like this: $(function() { $('.dynload').live('click', function(){ $('#ajaxloader').fadeIn('fast'); $('#ajaxloaderfridge').fadeIn('fast'); var href = this.href + ' #content'; $('#content').fadeOut('fast',function() { $(this).load(href,'', function(data) { createMenus(); $('#ajaxloader').fadeOut('fast'); $('#ajaxloaderfridge').fadeOut('fast'); $('#content').fadeIn('fast'); Cufon.replace('h1, h2, h3, h4, .menuwrapper', { fontFamily: 'advent'}); }); }); return false; }); }); $(createMenus); function createMenus() { $('#kontrollpanel .slidepanels').kwicks({ min : 42, spacing : 3, isVertical : true, sticky : true, event : 'click' }); } In the original code, #content is faded out, then the function "loadContent" is started. Which is basically what is happening in the new script as well isn't it? And when I was using the old code, the content just faded out and faded in really fast and smooth and with no small pause delay before the content arrived.

  • Preserve name of file using cURL to transfer files

    - by Toby
    I'm transferring files from an existing http request using cURL like so... $postargs = array( 'nonfilefield' =>'nonfilevalue', 'fileentry' => '@'.$_FILES['thefile']['tmp_name'][0] ); $ch = curl_init('http://localhost/curl/rec.php'); curl_setopt($ch,CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)"); curl_setopt($ch,CURLOPT_RETURNTRANSFER, true); curl_setopt($ch,CURLOPT_POST,TRUE); curl_setopt($ch,CURLOPT_POSTFIELDS,$postargs); curl_exec($ch); curl_close($ch); The only way I can get this to work is using the tmp_name, without this it won't send. However, I then lose the name value for when I want to name the file later. Is there some way to do this preserving the $_FILES array as it normally would be without curl? I'm also using an array of file fields in my script, so at the moment I have to convert my multidimensional array into a single dimension for this to work

  • WPF problem modify style of images in multiple Button Templates

    - by user556415
    I'm trying to create a control panel for a video camera, the panel has buttons for up, down, left and right etc. Each camera function up, down, left and right is represented by three images (see code below) for the left side, middle and right side. The control panel is circular so the corner images kind of overlap (its complicated to explain this without a visual). When I click on up for example I have to hide the initial three images (leftside, middle and right side) and display another three images for left , middle and right that indicate that the button is pressed. I am achieving this by having a grid inside a button template. The problem I have is that for the corner images for the control there are really four images that represent this. For example for the top left corner the four images would be represent 1. Top not clicked. 2. Top Clicked and 3. Left Not clicked and 4. Left Clicked. My problem is if I need to make the images contained within the Top button have precedence when the top control is clicked or the images in the left button have precedence when the left button is clicked. So it's like I want to modify the left button's image visible property when the top button is clicked and vise versa. This is really difficult to explain so I apologize if it makes little sense but I can email the source code on request if anyone is interested in my predicament. <Grid> <Canvas> <!--<StackPanel>-->

  • Ruby on rails 2 level model

    I need some help creating a very simple forum in a existing model. What I want in a Game page, have a mini forum, where is possible create some topics and some comments to this topics.

  • Java: How ArrayList memory management

    - by cka3o4nik
    In my Data Structures class we have studies the Java ArrayList class, and how it grows the underlying array when a user adds more elements. That is understood. However, I cannot figure out how exactly this class frees up memory when lots of elements are removed from the list. Looking at the source, there are three methods that remove elements: [code] public E remove(int index) { RangeCheck(index); modCount++; E oldValue = (E) elementData[index]; int numMoved = size - index - 1; if (numMoved 0) System.arraycopy(elementData, index+1, elementData, index, numMoved); elementData[--size] = null; // Let gc do its work return oldValue; } public boolean remove(Object o) { if (o == null) { for (int index = 0; index < size; index++) if (elementData[index] == null) { fastRemove(index); return true; } } else { for (int index = 0; index < size; index++) if (o.equals(elementData[index])) { fastRemove(index); return true; } } return false; } private void fastRemove(int index) { modCount++; int numMoved = size - index - 1; if (numMoved 0) System.arraycopy(elementData, index+1, elementData, index, numMoved); elementData[--size] = null; // Let gc do its work } {/code] None of them reduce the datastore array. I even started questioning if memory free up ever happens, but empirical tests show that it does. So there must be some other way it is done, but where and how? I checked the parent classes as well with no success.

  • My code is really slow in IE8. But in Safari,firefox,chrome it works great.

    - by bamic01
    Hello all, iam stuck now, i really hope if somebody can tell me the problems what i really don't see. The problem is is the menubar works great in Safari,FF,Chrome. But when i open IE8 its so slow when i put my mouse cursor on another menu area. Or better the entire menu is just so slow! html id & class are <div class="oe_wrapper"> <ul id="oe_menu" class="oe_menu"> this is my javascript code: $(function () { var $oe_menu = $('#oe_menu'); var $oe_menu_items = $oe_menu.children('li'); var $oe_overlay = $('#oe_overlay'); $oe_menu_items.bind('mouseenter', function () { var $this = $(this); $this.addClass('slided selected'); $this.children('div').css('z-index', '9999').stop(true, true).slideDown(300, function () { $oe_menu_items.not('.slided').children('div').hide(); $this.removeClass('slided'); }); }).bind('mouseleave', function () { var $this = $(this); $this.removeClass('selected').children('div').css('z-index', '1'); }); $oe_menu.bind('mouseenter', function () { var $this = $(this); $this.addClass('hovered'); }).bind('mouseleave', function () { var $this = $(this); $this.removeClass('hovered'); $oe_menu_items.children('div').hide(); }) });

  • Is there a faster method to match an arbitrary String to month name in Java

    - by jonc
    Hello, I want to determine if a string is the name of a month and I want to do it relatively quickly. The function that is currently stuck in my brain is something like: boolean isaMonth( String str ) { String[] months = DateFormatSymbols.getInstance().getMonths(); String[] shortMonths = DateFormatSymbols.getInstance().getShortMonths(); int i; for( i = 0; i<months.length(); ++i;) { if( months[i].equals(str) ) return true; if( shortMonths[i].equals(str ) return true; } return false; } However, I will be processing lots of text, passed one string at a time to this function, and most of the time I will be getting the worst case of going through the entire loop and returning false. I saw another question that talked about a Regex to match a month name and a year which could be adapted for this situation. Would the Regex be faster? Is there any other solution that might be faster?

  • jquery dialog calls a server side method with button parameters

    - by Chiefy
    Hello all, I have a gridview control with delete asp:ImageButton for each row of the grid. What I would like is for a jquery dialog to pop up when a user clicks the delete button to ask if they are sure they want to delete it. So far I have the dialog coming up just fine, Ive got buttons on that dialog and I can make the buttons call server side methods but its getting the dialog to know the ID of the row that the user has selected and then passing that to the server side code. The button in the page row is currently just an 'a' tag with the id 'dialog_link'. The jquery on the page looks like this: $("button").button(); $("#DeleteButton").click(function () { $.ajax({ type: "POST", url: "ManageUsers.aspx/DeleteUser", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { // Replace the div's content with the page method's return. $("#DeleteButton").text(msg.d); } }); }); // Dialog $('#dialog').dialog({ autoOpen: false, width: 400, modal: true, bgiframe: true }); // Dialog Link $('#dialog_link').click(function () { $('#dialog').dialog('open'); return false; }); The dialog itself is just a set of 'div' tags. Ive thought of lots of different ways of doing this (parameter passing, session variable etc...) but cant figure out how to get any of them working. Any ideas are most welcome As always, thanks in advance to those who contribute.

  • Another thread safe queue implementation

    - by jensph
    I have a class, Queue, that I tried to make thread safe. It has these three member variables: std::queue<T> m_queue; pthread_mutex_t m_mutex; pthread_cond_t m_condition; and a push and pop implemented as: template<class T> void Queue<T>::push(T value) { pthread_mutex_lock( &m_mutex ); m_queue.push(value); if( !m_queue.empty() ) { pthread_cond_signal( &m_condition ); } pthread_mutex_unlock( &m_mutex ); } template<class T> bool Queue<T>::pop(T& value, bool block) { bool rtn = false; pthread_mutex_lock( &m_mutex ); if( block ) { while( m_queue.empty() ) { pthread_cond_wait( &m_condition, &m_mutex ); } } if( !m_queue.empty() ) { value = m_queue.front(); m_queue.pop(); rtn = true; } pthread_mutex_unlock( &m_mutex ); return rtn; } Unfortunately there are occasional issues that may be the fault of this code. That is, there are two threads and sometimes thread 1 never comes out of push() and at other times thread 2 never comes out of pop() (the block parameter is true) though the queue isn't empty. I understand there are other implementations available, but I'd like to try to fix this code, if needed. Anyone see any issues? The constructor has the appropriate initializations: Queue() { pthread_mutex_init( &mMutex, NULL ); pthread_cond_init( &mCondition, NULL ); } and the destructor, the corresponding 'destroy' calls.

  • Embedded Youtube video in a Ruby on Rails page

    - by dan
    Hi, New to programming. I am trying to embed a YouTube video from a link stored in a database named "Promoter" into a ruby-on-rails page (.erb).

  • User input being limited to the alphabet in python

    - by Danger Cat
    I am SUPER new to programming and have my first assignment coming up in python. I am writing a hangman type game, where users are required to guess the word inputted from the other user. I have written most of the code, but the only problem I am having is when users have to input the word, making sure it is only limited to the alphabet. The code I have so far is : word = str.lower(raw_input("Type in your secret word! Shhhh... ")) answer = True while answer == True: for i in range(len(word)): if word[i] not in ("abcdefghijklmnopqrstuvwxyz"): word = raw_input("Sorry, words only contain letters. Please enter a word ") break else: answer = False This works while I input a few tries, but eventually will either exit the loop or displays an error. Is there any easier way to use this? We've really only covered topics up to loops in class, and break and continue are also very new to me. Thank you! (Pardon if the code is sloppy, but as I said I am very new to this....)

  • Android onFling not responding

    - by Kevin Moore
    I am new to android first of all so think of any newbie mistakes first I am trying to add a fling function in my code. public class MainGamePanel extends SurfaceView implements SurfaceHolder.Callback, OnGestureListener { private MainThread thread; private Droid droid; private Droid droid2; private static final String TAG = gameView.class.getSimpleName(); private GestureDetector gestureScanner; public MainGamePanel(Context context){ super(context); getHolder().addCallback(this); droid = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 270, 300); droid2 = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 50, 300); thread = new MainThread(getHolder(), this); setFocusable(true); gestureScanner = new GestureDetector(this); } public boolean onTouchEvent(MotionEvent event){ return gestureScanner.onTouchEvent(event); } @Override protected void onDraw(Canvas canvas){ canvas.drawColor(Color.BLACK); droid.draw(canvas); droid2.draw(canvas); } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { droid.setX(50); droid.setY(50); Log.d(TAG, "Coords: x=" + e1.getX() + ",y=" + e2.getY()); return true; } @Override public boolean onDown(MotionEvent e) { droid2.setX((int)e.getX()); droid2.setY((int)e.getY()); Log.d(TAG, "Coords: x=" + e.getX() + ",y=" + e.getY()); return false; } I got the gestureListener to work with: onDown, onLongPress, and onShowPress. But i can't get any response with onFling, onSingleTapUp, and onScroll. What mistake am I making? does it have to do with views? I don't know what code would be useful to see.... so any suggestions would be much appreciated. Thank You!

  • sortable list using jquery ui not passing updated list order

    I am following the sortable lists railscast and got everything working except when I sort, the same (original) order gets passed to the update method each time, so it doesn't update the true order. Here's the code: In the view: %tbody#lineup{"data-update-url" => sort_lineups_url} - @lineup.pieces.each_with_index do |piece, index| = content_tag_for :tr, piece do = render 'piece', :piece => piece, :index => index and pieces.js.coffee: jQuery -> $('#lineup').sortable( axis: 'y' update: -> $.post($(this).data('update-url'), $(this).sortable('serialize')) ); sort and show methods of lineupscontroller: def show @lineup = Lineup.find_by_user_id(current_user.id) @pieces = @lineup.pieces.order("position") end def sort params[:piece].each_with_index do |id, index| current_user.lineup.pieces.update_all({position: index+1}, {id: id}) end render nothing: true end and the update request: Started POST "/lineups/sort" for 127.0.0.1 at 2012-06-24 20:06:14 -0700 Processing by LineupsController#sort as */* Parameters: {"piece"=>["8", "2", "1", "4", "3", "7"]} User Load (0.4ms) SELECT `users`.* FROM `users` WHERE `users`.`id` = 2 LIMIT 1 Lineup Load (0.6ms) SELECT `lineups`.* FROM `lineups` WHERE `lineups`.`user_id` = 2 LIMIT 1 SQL (2.9ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 1 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 8 SQL (0.6ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 2 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 2 SQL (0.6ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 3 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 1 SQL (0.5ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 4 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 4 SQL (0.6ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 5 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 3 SQL (0.5ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 6 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 7 Rendered text template (0.0ms) so each time i drag+drop the list, it sends the same order again. what am I doing wrong that the params isn't passing the right, updated order?

  • Accessing Application Scoped Bean Causes NullPointerException

    - by user2946861
    What is an Application Scoped Bean? I understand it to be a bean which will exist for the life of the application, but that doesn't appear to be the correct interpretation. I have an application which creates an application scoped bean on startup (eager=true) and then a session bean that tries to access the application scoped bean's objects (which are also application scoped). But when I try to access the application scoped bean from the session scoped bean, I get a null pointer exception. Here's excerpts from my code: Application Scoped Bean: @ManagedBean(eager=true) @ApplicationScoped public class Bean1 implements Serializable{ private static final long serialVersionUID = 12345L; protected ArrayList<App> apps; // construct apps so they are available for the session scoped bean // do time consuming stuff... // getters + setters Session Scoped Bean: @ManagedBean @SessionScoped public class Bean2 implements Serializable{ private static final long serialVersionUID = 123L; @Inject private Bean1 bean1; private ArrayList<App> apps = bean1.getApps(); // null pointer exception What appears to be happening is, Bean1 is created, does it's stuff, then is destroyed before Bean2 can access it. I was hoping using application scoped would keep Bean1 around until the container was shutdown, or the application was killed, but this doesn't appear to be the case.

  • User to be validated against nested security groups in Windows.

    - by user412272
    Hi, This is my first post here and after much looking around I have come here with my question. Will really appreciate a fast response. I am faced with a problem to validate user credentials of the currently logged on user against a group in Windows. The user membership to a group can be through other groups also ie nested membership. Eg. User U is a part of group G1. Group G1 is a part of another group G2. The requirement is that when the user is validated against group G2, the validations should succeed. The user can be a local or AD user but the group will always be a local group ( or domain local group if created directly on a DC). I have tried using WindowsPrincipal.IsInRole() method, but it seems to be checking only for direct membership to a group. I also tried UserPrincipal.GetAuthorizationGroups() for the current user, but it also doesnt seem to be doing recursive search. I am posting a code snippet of the working code below, but this code is taking much more than acceptable time. bool CheckUserPermissions(string groupName) { WindowsIdentity currentUserIdentity = System.Security.Principal.WindowsIdentity.GetCurrent(); bool found = false; PrincipalContext context= new PrincipalContext(ContextType.Machine); GroupPrincipal group = GroupPrincipal.FindByIdentity(context, IdentityType.Name, groupName); if (group!= null) { foreach (Principal p in group.GetMembers(true)) { if (p.Sid == currentUserIdentity.User) { found = true; break; } } group.Dispose(); } return found; }

    - by user1734230
    I have problem i'm trying to update a specific part of the XML with the linq query but it doesn't work. So i an xml file: <?xml version="1.0" encoding="utf-8"?> <DesignConfiguration> <Design name="CSF_Packages"> <SourceFolder>C:\CSF_Packages</SourceFolder> <DestinationFolder>C:\Documents and Settings\xxx</DestinationFolder> <CopyLookups>True</CopyLookups> <CopyImages>False</CopyImages> <ImageSourceFolder>None</ImageSourceFolder> <ImageDesinationFolder>None</ImageDesinationFolder> </Design> </DesignConfiguration> I want to select the part where the part where there is Design name="somethning" and get the descendants and then update the descendants value that means this part: <SourceFolder>C:\CSF_Packages</SourceFolder> <DestinationFolder>C:\Documents and Settings\xxx</DestinationFolder> <CopyLookups>True</CopyLookups> <CopyImages>False</CopyImages> <ImageSourceFolder>None</ImageSourceFolder> <ImageDesinationFolder>None</ImageDesinationFolder> I have this code: XDocument configXml = XDocument.Load(configXMLFileName); var updateData = configXml.Descendants("DesignConfiguration").Elements().Where(el => el.Name == "Design" && el.Attribute("name").Value.Equals("AFP_GRAFIKA")).FirstOrDefault(); configXml.Save(configXMLFileName); I'm getting the null data in the updateData varibale. When I'm trying the Descendat's function through QuickWatch it also returns a null value. When I'm checking the configXML variable it has data that is my whole xml. What am I doing wrong?

  • Monotouch auto resizing views in iphone

    - by Tim Bassett
    I have created a view in interface builder that contains another view (content area) and a button bar at the bottom. The hierarchy is as: ->View --->mapContainer UIView ----->map MKMapView ----->OverlayView UIView --->ToolBar UIToolBar I would like the mapContainer to resize to full window when the ToolBar is hidden. I would like the map and the OverlayView to resize to the mapContainer size I have attempted the following code, but it has no effect. Please advise? public override void ViewDidLoad () { base.ViewDidLoad (); this.mapContainer.AutosizesSubviews = true ; this.View.AutosizesSubviews = true ; try { this.mapContainer.AutoresizingMask = UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleWidth ; this.map.AutoresizingMask = UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleWidth ; this.map.SizeToFit(); this.mapContainer.SizeToFit(); this.map.SizeToFit(); this.View.Frame = new System.Drawing.RectangleF(0,0,this.View.Frame.Width, this.View.Frame.Height ); this.mapContainer.LayoutSubviews(); } catch(Exception ex) { Console.Write(ex.ToString()); } }

  • Cannot locate record in delphi ADO query

    - by Danatela
    I can't locate any record in TADOQuery using PK. First, I was trying to use standard Locate method: PPUQuery.Locate('ID', SpPlansQuery['PPONREC'], []); It always returns False, but manual search (passing the whole query matching ID with given PPONREC which is really slow) finds the desired row. I tried using loPartialKey and switched CursorLocation of query to clUseServer, but it didn't help. Next, I tried to filter my PPUQuery: PPUQuery.Filter := 'ID = ' + VarToStr(SpPlansQuery['PPONREC']); PPUQuery.Filtered := True; PPUQuery.First; But after that the PPUQuery.Eof is True and PPUQuery.RecordCount equals 0. Underlying database is Oracle 9 and the ID is of type INTEGER and is PK of table TPORDER_CMK. PPUQuery.SQL is: SELECT tp.*, la.*, lm.*, ld.*, ld1.*, to_cmk.* FROM ppu_plan.tporder_cmk tp JOIN PPU_PLAN.LARTICLES la ON TP.ARTICLE = LA.ID JOIN PPU_PLAN.LMATERIAL lm ON TP.MATERIAL = lm.id JOIN PPU_PLAN.LCADEP ld ON TP.CADEP = LD.ID JOIN PPU_PLAN.LCADEP ld1 ON TP.PRODUCER = LD1.ID JOIN PPU_PLAN.TORDER_CMK to_cmk ON TP.order_id=TO_cmk.ID WHERE TP.PLAN_ID = :pplan_id What should I try next and how to solve this problem?

  • Ruby - RegEx problem or maybe another solution altogether

    - by r3nrut
    Ok the problem I'm having is that I have a block of javascript I've successfully scraped out of a websites source and now I have to sift through the js to get the specific values I'm looking for. Below is the chunk i'm needing to deal with. I need to find "flvFileName" and get all the file names listed. In this case its: trailer1,trailer2,trailer3. At first I started using regex to match the start and end tags and them match the file names and extract them to an array but the problem is that there isn't always 3 videos in the list. Could be 0, 1, 2, 3, 4 etc. So matching doesn't work. Any thoughts on a way to approach this that won't make me continue to abuse my laptop? ["", "\r\n", "\n", "\r\n function IgnoreEnter(e) {\r\n var code;\r\n if (!e) // IE\r\n {\r\n var e = window.event;\r\n }\r\n if (e.keyCode) {\r\n code = e.keyCode;\r\n }\r\n else if (e.which) // Firefox, Opera\r\n {\r\n code = e.which;\r\n }\r\n\r\n if (code == 13) {\r\n e.cancelBubble = true;\r\n e.returnValue = false;\r\n }\r\n }\r\n\r\n function ResetDefault() {\r\n __defaultFired = false;\r\n }\r\n", "", "\r\n// <![CDATA[\r\n$(doc).ready(function () { $('#VideoObject').flash({ swf: '/scinema/video.swf', height: 300, width: 480, hasVersion: 8, menu: false, wmode: 'transparent', bgcolor: '#000',flashvars: {flvFileName: 'trailer1,trailer2,trailer3', age: 'no', isForced: 'true'} }); });

  • How to check of which user-defined type a current JSON element is during $.each()?

    - by Bob
    I have the following structure for a JSON file: ({condos:[{Address:'123 Fake St.', Lat:'56.645654', Lng:'23.534546'},{... another condo ...},{...}],houses:[{Address:'1 Main Ave.', Lat:'34.765766', Lng:'27.8786674'},{... another house ...}, {...}]}) So, I have a list of condos and houses in one big JSON array. I want to plot them all on my map, but I want to give condos and houses different marker icons( blue marker for condos, green marker for houses ). Problem I have is - figuring out how to distinguish between types of markers when I $.each() through them. How would I use if to check whether I'm working with a condo or a house at the moment? var markers = null; $('#map').gmap(mapOptions).bind('init', function(){ $.post('getMarkers.php', function(json){ markers = json; $.each(markers, function(type, dataMembers) { $.each(dataMembers, function(i, j){ //if house use house.png to create marker $('#map').gmap('addMarker', { 'position': new google.maps.LatLng(parseFloat(Lat), parseFloat(Lng)), 'bounds':true, 'icon':'house.png' } ); //if condo use condo.png $('#map').gmap('addMarker', { 'position': new google.maps.LatLng(parseFloat(Lat), parseFloat(Lng)), 'bounds':true, 'icon':'condo.png' } ); }); }); }); });

  • Saving a Record with Rails Association

    - by tshauck
    Hi, I've been going through the Rails Guides, but have gotten stuck on associations after going through validations and migrations. So, I have the following models Job and Person, where a Person can have many jobs. I know that in reality there'd be a many-to-many, but I'm trying to get my handle on this first. class Job < ActiveRecord::Base belongs_to :people end and class Person < ActiveRecord::Base has_many :jobs end Here's the schema ActiveRecord::Schema.define(:version => 20110108185924) do create_table "jobs", :force => true do |t| t.string "occupation" t.boolean "like" t.datetime "created_at" t.datetime "updated_at" t.integer "person_id" end create_table "people", :force => true do |t| t.string "first_name" t.string "last_name" t.datetime "created_at" t.datetime "updated_at" end end Is there some I can do the following j = Job.first; j.Person? Then that'd give me access to the Person object associated with the j. I couldn't find it on guides.rubyonrails.org, although it has been very helpful getting a grip on migrations and validations thus far. Thanks PS, If there are any tutorials that covers more of this kind of things links would be great.
