  • Array within Form collecting multiple values with the same name possible?

    - by JM4
    Good afternoon, I will first start with the goal I am trying to accomplish and then give a very basic sample of what I need to do. Goal Instead of collecting several variables and naming them with keys individually, I have decided to give in and use an array structure to handle all inputs of the same type and rules. Once I have the variables, I will validate against them and if 'ok' store them in a MySQL table. The table will hold consumer information and will need to store multiple rows of the same type of information. First Pass I will leave out the validation portion of this question because I feel I need to first understand the basics. <form action="?" method="POST" name="Form"> Member 1 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 1 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 1 Email: <input type="text" name="MemberEmail[]" /><br /> Member 2 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 2 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 2 Email: <input type="text" name="MemberEmail[]" /><br /> Member 3 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 3 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 3 Email: <input type="text" name="MemberEmail[]" /><br /> <input type="submit" name="submit" value="Continue" /> </form> I am hoping that each input given for First Name (a required field) will generate a unique key for that particular entry and not overwrite any data entered. Because I am carrying information from page to page (checkout form), I am turning the POST variables into SESSION variables then storing in a mysql database in the end. My hope is to have: <?php $conn = mysql_connect("localhost", "username", "password"); mysql_select_db("DBname",$conn); $sql = "INSERT INTO tablename VALUES ('$_SESSION[Member1FirstName]', '$_SESSION[Member1LastName]', '$_SESSION[Member1Email]', '$_SESSION[Member2FirstName]', '$_SESSION[Member2LastName]', '$_SESSION[Member2Email]', '$_SESSION[Member1FirstName]', '$_SESSION[Member3LastName]', '$_SESSION[Member3Email]')"; $result = mysql_query($sql, $conn) or die(mysql_error()); Header ("Location: completed.php"); ?> Where Member1, Member2, and Member3 values will appear on their own row within the table. I KNOW my code is wrong but I am giving a first shot at the overall business purpose I am trying to achieve and trying to learn how to code the right way. I am very, very new to programming so any 'baby advice' is greatly appreciated.

  • jQuery Table - Reference User Input Row Names and Values

    - by Vic
    I have several tables which are generated by another application, which I have no control over. I am totally new to jQuery and ajax, and have only a limited knowledge of jsp. Two sample rows are: <table class="sicknessForm"> <tr id="row_0" class="datarow"> <td id="col_2"><input name="row_0-col_2" class="tabcell" value="Injuries"></td> <td id="col_4"><input name="row_0-col_4" class="tabcell" value="01"></td> <td id="col_5"><input name="row_0-col_5" class="tabcell" value="2"></td> <td id="col_6"><input name="row_0-col_6" class="tabcell" value="5"></td> </tr> <tr id="row_1" class="datarow"> <td id="col_2"><input name="row_1-col_2" class="tabcell" value="Absences"></td> <td id="col_4"><input name="row_1-col_4" class="tabcell" value="100"></td> <td id="col_5"><input name="row_1-col_5" class="tabcell" value="102"></td> <td id="col_6"><input name="row_1-col_6" class="tabcell" value="105"></td> </tr> </table> There are more rows and columns in the actual tables. What I need to do is to pass the ordered row information to the database, e.g.: Injuries, 1, 2, 5 .... Absences 100, 102, 105... I can retrieve the values for each input using: $('#SicknessForm .userInput').each(function() { alert($(this).val()); }); 1) How can I loop through each row, get the value from the first column (Injuries) and place the data into an array to send to the server? 2) How do I reference the first row of each column to disable user input on it? $(:HowDoIReferenceThis).attr('disabled', ''); 3) I need to validate that each cell is numeric, other than the first column. Any pointers on this (otherwise I can check it in my servlet), especially on how to loop through all valid input cells (everything except 'Injuries','Abences', ... cells). Many Thanks! Vic

  • How to read XML parent node tag value

    - by kaibuki
    HI Guys, I have a java code to read XML nodes, I want to add in the addition and want to read the parent node value also. my XML file sample is below: <breakfast_menu><food id=1><name> Belgian Waffles </name><price> $5.95 </price><description> two of our famous Belgian Waffles with plenty of real maple syrup </description><calories> 650 </calories></food><food id=2><name>Strawberry Belgian waffles</name><price>$7.95</price><description>light Belgian waffles covered with strawberries and whipped cream</description><calories>900</calories></food></breakfast_menu> and my code for parsing xml is : public static String getProductItem(String pid, String item) { try { url = new URL(""); urlConnection = url.openConnection(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { } try { dBuilder = dbFactory.newDocumentBuilder(); } catch (ParserConfigurationException e) { } try { doc = dBuilder.parse(urlConnection.getInputStream()); } catch (SAXException e) { } catch (IOException e) { } doc.getDocumentElement().normalize(); NodeList nList = doc.getElementsByTagName("food"); for (int temp = 0; temp < nList.getLength(); temp++) { Node nNode = nList.item(temp); if (nNode.getNodeType() == Node.ELEMENT_NODE) { Element eElement = (Element) nNode; data = getTagValue(item, eElement); } } doc = null; dBuilder = null; return data; } private static String getTagValue(String sTag, Element eElement) { NodeList nlList = eElement.getElementsByTagName(sTag).item(0) .getChildNodes(); Node nValue = (Node) nlList.item(0); return nValue.getNodeValue(); } What I want to do is to read the "id" value of food, so if if I am searching for a food, it only checks those food nodes, whose id matched the food node id. thanks in advance. cheers.. kai

  • Using a Button to navigate to another Page in a NavigationWindow

    - by Will
    I'm trying to use the navigation command framework in WPF to navigate between Pages within a WPF application (desktop; not XBAP or Silverlight). I believe I have everything configured correctly, yet its not working. I build and run without errors, I'm not getting any binding errors in the Output window, but my navigation button is disabled. Here's the app.xaml for a sample app: <Application x:Class="Navigation.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="First.xaml"> </Application> Note the StartupUri points to First.xaml. First.xaml is a Page. WPF automatically hosts my page in a NavigationWindow. Here's First.xaml: <Page x:Class="Navigation.First" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="First"> <Grid> <Button CommandParameter="/Second.xaml" CommandTarget="{Binding RelativeSource= {RelativeSource FindAncestor, AncestorType={x:Type NavigationWindow}}}" Command="NavigationCommands.GoToPage" Content="Go!"/> </Grid> </Page> The button's CommandTarget is set to the NavigationWindow. The command is GoToPage, and the page is /Second.xaml. I've tried setting the CommandTarget to the containing Page, the CommandParameter to "Second.xaml" (First.xaml and Second.xaml are both in the root of the solution), and I've tried leaving the CommandTarget empty. I've also tried setting the Path to the Binding to various navigational-related public properties on the NavigationWindow. Nothing has worked so far. What am I missing here? I really don't want to do my navigation in code. Clarification. If, instead of using a button, I use a Hyperlink: <Grid> <TextBlock> <Hyperlink NavigateUri="Second.xaml">Go! </Hyperlink> </TextBlock> </Grid> everything works as expected. However, my UI requirements means that using a Hyperlink is right out. I need a big fatty button for people to press. That's why I want to use the button to navigate. I just want to know how I can get the Button to provide the same ability that the Hyperlink does in this case.

  • How do you clear RootLayoutPanel in GWT?

    - by kerrr
    I have Buttons attached to elements on the modules entrypoint html page using RootPanel.get("foo").add(button). If I subsequently create a LayoutPanel and attach it using RootLayoutPanel.get.add(layoutpanal) then the buttons cannot be clicked. This is all fine. If I then try and remove the layoutpanel or clear the RootLayoutPanel the buttons still cannot be clicked. Any ideas how to clear this? Have I missed a step or should you simply never try and get back to using a page's RootPanel if you have used a RootLayoutPanel? Sample code: public void onModuleLoad(){ final LayoutPanel lp1=new LayoutPanel(); ClickPanel ping=new ClickPanel("Ping"); ping.getElement().getStyle().setBackgroundColor( "#fdd" ); ping.addClickHandler( new ClickHandler(){ @Override public void onClick( ClickEvent event ){ Window.alert( "Ping!!!" ); //lp1.removeFromParent(); //RootLayoutPanel.get().remove(lp1); //RootLayoutPanel.get().removeFromParent(); RootLayoutPanel.get().clear(); } } ); ClickPanel bong=new ClickPanel("Bong"); bong.getElement().getStyle().setBackgroundColor( "#ddf" ); bong.addClickHandler( new ClickHandler(){ @Override public void onClick( ClickEvent event ){ Window.alert( "Bong!!!" ); } } ); lp1.add( ping ); lp1.setWidgetLeftWidth( ping, 100, Style.Unit.PX, 500, Style.Unit.PX ); lp1.setWidgetTopHeight( ping, 100, Style.Unit.PX, 500, Style.Unit.PX ); lp1.add( bong ); lp1.setWidgetLeftWidth( bong, 50, Style.Unit.PCT, 600, Style.Unit.PX ); lp1.setWidgetTopHeight( bong, 50, Style.Unit.PCT, 200, Style.Unit.PX ); Button b=new Button("Click Me"); b.addClickHandler( new ClickHandler(){ @Override public void onClick( ClickEvent event ){ RootLayoutPanel.get().add( lp1 ); } } ); RootPanel.get("button1").add( b ); } ClickPanel is simply overrides HTMLPanel implementing HasClickHandelers. Clicking "Click Me" opens the layout panel. Clicking the panel ping gets rid of the layout panel, but the button "Click Me" cannot be clicked. I've tried various options.

  • Strange behavior of move with strings

    - by Umair Ahmed
    I am testing some enhanced string related functions with which I am trying to use move as a way to copy strings around for faster, more efficient use without delving into pointers. While testing a function for making a delimited string from a TStringList, I encountered a strange issue. The compiler referenced the bytes contained through the index when it was empty and when a string was added to it through move, index referenced the characters contained. Here is a small downsized barebone code sample:- unit UI; interface uses System.SysUtils, System.Types, System.UITypes, System.Rtti, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Dialogs, FMX.Layouts, FMX.Memo; type TForm1 = class(TForm) Results: TMemo; procedure FormCreate(Sender: TObject); end; var Form1: TForm1; implementation {$R *.fmx} function StringListToDelimitedString ( const AStringList: TStringList; const ADelimiter: String ): String; var Str : String; Temp1 : NativeInt; Temp2 : NativeInt; DelimiterSize : Byte; begin Result := ' '; Temp1 := 0; DelimiterSize := Length ( ADelimiter ) * 2; for Str in AStringList do Temp1 := Temp1 + Length ( Str ); SetLength ( Result, Temp1 ); Temp1 := 1; for Str in AStringList do begin Temp2 := Length ( Str ) * 2; // Here Index references bytes in Result Move ( Str [1], Result [Temp1], Temp2 ); // From here the index seems to address characters instead of bytes in Result Temp1 := Temp1 + Temp2; Move ( ADelimiter [1], Result [Temp1], DelimiterSize ); Temp1 := Temp1 + DelimiterSize; end; end; procedure TForm1.FormCreate(Sender: TObject); var StrList : TStringList; Str : String; begin // Test 1 : StringListToDelimitedString StrList := TStringList.Create; Str := ''; StrList.Add ( 'Hello1' ); StrList.Add ( 'Hello2' ); StrList.Add ( 'Hello3' ); StrList.Add ( 'Hello4' ); Str := StringListToDelimitedString ( StrList, ';' ); Results.Lines.Add ( Str ); StrList.Free; end; end. Please devise a solution and if possible, some explanation. Alternatives are welcome too.

  • QGraphicsView and custom Cursors

    - by Etienne de Martel
    I am trying to make use of a mix of custom cursors and preset cursors for my QGraphicsView. In my implementation we have created a notion of "modes" for the view. Meaning that depending on what "mode" the user is in, different things will happen on the left-click, or left-click drag. Anyway, none of that is the problem, just the context. The problem arises when I try to change the cursor for each mode. For instance, for mode 1 we want to show the regular Arrow cursor, but for mode 2, we want to use a custom pixmap. Seemingly simple we call graphicsview->viewport()->setCursor(Qt::QArrowCursor)  when we are switching to mode 1, and graphicsview->viewport()->setCursor(our custom cursor) for mode 2. Except it doesn't work at all. Firstly, the cursor does not change to the custom cursor. That is the first problem. However, if through another operation the drag mode of the graphics view gets set to ScrollHandDrag, the cursor will switch to the custom cursor once the drag operation is complete. Weird. But the plot thickens... Once we switch to the custom cursor, it can never be changed back to the ArrorCursor no matter how many times we call setCursor(Qt::QArrowCursor). it also doesn't seem to matter whether I call setCursor on the viewport or the graphics view itself. So, just for fun, I added a call to graphicsview->unsetCursor() just before we want to change the cursor, and that at least rectifies the second problem. The cursor changes just fine so long as we do a little HandDragging in between. Better, but certainly not optimal. However it should be noted, that doing the unsetCursor on the viewport doesn't work. it must absolutely be done on the graphicsview - regardless of the fact that we are setting the cursor on the viewport. To completely patch over the problem I have added these two lines after I set the cursor: graphicsview->setDragMode(QGraphicsView::ScrollHandDrag); graphicsview->setDragMode(QGraphicsView::NoDrag); Which works, but ye gads!! So something magical is happening inside these two methods that fixes the problem, but glancing at the code I don't see what. Something to do with the fact that the drag mode is changing the cursor I imagine. Just for completeness, I should also mention that the thing that triggers the mode change, is a QPushButton that has been added to the scene using QGraphicsScene->addWidget(). I don't know if that has anything to do with it, but you never know. I am hoping that either someone could clarify why I need to make these seemingly random calls. I don't think I am doing anything wrong anywhere. Thanks in advance for any help. EDIT: Here is an actual code example with the cursor patches as described above. You can look at and/or download them from the link below. It was a little long to paste here. I included the framework around which the cursors are changed, because I have a funny feeling that that is important somehow. https://gist.github.com/712654 The code where the problem lies is in MyGraphicsView.cpp starting at line 104. This is where the cursor is set in the graphics view. It is exactly as described above. Keep in mind, with the very ugly patches in place the cursors do work - more or less. Without those lines you will see very clearly the problems listed in the post above. Also included in the link, is all the code for a mainWindow that uses the view, etc... the only thing missing are the images I am using. But the images themselves don't matter, any 16x16 pngs will do.

  • Problem with jQuery accordion and cookies

    - by rayne
    I have a jQuery accordion from this site and edited for my purposes, but the accordion only works in Firefox (not Safari or Chrome) and the cookies aren't being set correctly. This is the jQuery: function initMenus() { $('#sidebar .letter_index').hide(); $.each($('#sidebar .letter_index'), function() { var cookie = $.cookie(this.id); if (cookie === null || String(cookie).length < 1) { $('#sidebar .letter_index:first').show(); } else { $('#' + this.id + ' .' + cookie).next().show(); } }); $('#sidebar .letter_head').click(function() { var checkElement = $(this).next(); var parent = this.parentNode.parentNode.id; if ((checkElement.is('.letter_index')) && (!checkElement.is(':visible'))) { $('#' + parent + ' .letter_index:visible').slideUp('normal'); if ((String(parent).length > 0) && (String(this.className).length > 0)) { // not working - wie ändert man das this.class so das die class abc oder def gesetzt wird anstatt this?! $.cookie(parent, this.className); } checkElement.slideDown('normal'); return false; } } ); } $(document).ready(function() {initMenus();}); This is how my HTML looks (sample item): <div id="sidebar"> <h2 class="letter_head"><a href="#" class="ABC">ABC</h2> <ul class="letter_index"> <li>Abc</li> <li>Bcd</li> </ul> </div> I can't find the problem why the script won't work in Safari and Chrome. I also don't know how to tell it to use the class of the a inside the h2 as the cookie value. (Currently the cookie is set as $.cookie(parent, this.className);, which produces cookies with the name container (the div above #sidebar) and the value letter_head. It needs to be something like 'sidebar' and 'ABC', 'DEF' and so on. Thanks in advance!

  • UITableView: Handle cell selection in a mixed cell table view static and dynamic cells

    - by AlexR
    I am trying to mix dynamic and static cells in a grouped table view: I would like to get two sections with static cells at the top followed by a section of dynamic cells (please refer to the screenshot below). I have set the table view contents to static cells. Edit Based on AppleFreak's advice I have changed my code as follows: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell; if (indexPath.section <= 1) { // section <= 1 indicates static cells cell = [super tableView:tableView cellForRowAtIndexPath:indexPath]; } else { // section > 1 indicates dynamic cells CellIdentifier = [NSString stringWithFormat:@"section%idynamic",indexPath.section]; cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; } return cell; } However, my app crashes with error message Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:' for section 0 and row 0. The cell returned from cell = [super tableView:tableView cellForRowAtIndexPath:indexPath] for section 0 and row 0 is nil. What is wrong with my code? Could there be any problems with my outlets? I haven't set any outlets because I am subclassing UITableViewController and supposedly do not any outlets for tableview to be set (?). Any suggestions on how to better do it? Edit II I have recreated my scene in storyboard (please refer to my updated screen shot above) and rewritten the view controller in order to start from a new base. I have also read the description in Apple's forum as applefreak suggested. However, I run in my first problem with the method numberOfSectionsInTableView:tableView, in which I increment the number of static sections (two) by one. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return [super numberOfSectionsInTableView:tableView] + 1 ; } The app crashed with the error message: Terminating app due to uncaught exception 'NSRangeException', reason: '* -[__NSArrayI objectAtIndex:]: index 2 beyond bounds [0 .. 1]' Why is this code not working for me even though I followed Apple's and applefreak recommendations? It is possible that the tableView has changed a bit in iOS 6? Solution: I got this to work now using AppleFreaks code sample in his answer below. Thank you, AppleFreak! Edit III: Cell Selection: How can I handle cell selection in a mixed (dynamic and static cells) cell table view? When do I call super and when do I call self tableView? When I use [[super tableView] selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone] and try to check for the selected index paths with: UITableView *tableView = [super tableView]; if ( [[tableView indexPathForSelectedRow] isEqual:customGrowthIndexPath] ) { .. } I get an return value of nil. As I can't find the source of my error, I really would appreciate your help

  • SelectedItem in ListView binding

  • Idiomatic use of auto_ptr to transfer ownership to a container

    - by heycam
    I'm refreshing my C++ knowledge after not having used it in anger for a number of years. In writing some code to implement some data structure for practice, I wanted to make sure that my code was exception safe. So I've tried to use std::auto_ptrs in what I think is an appropriate way. Simplifying somewhat, this is what I have: class Tree { public: ~Tree() { /* delete all Node*s in the tree */ } void insert(const string& to_insert); ... private: struct Node { ... vector<Node*> m_children; }; Node* m_root; }; template<T> void push_back(vector<T*>& v, auto_ptr<T> x) { v.push_back(x.get()); x.release(); } void Tree::insert(const string& to_insert) { Node* n = ...; // find where to insert the new node ... push_back(n->m_children, auto_ptr<Node>(new Node(to_insert)); ... } So I'm wrapping the function that would put the pointer into the container, vector::push_back, and relying on the by-value auto_ptr argument to ensure that the Node* is deleted if the vector resize fails. Is this an idiomatic use of auto_ptr to save a bit of boilerplate in my Tree::insert? Any improvements you can suggest? Otherwise I'd have to have something like: Node* n = ...; // find where to insert the new node auto_ptr<Node> new_node(new Node(to_insert)); n->m_children.push_back(new_node.get()); new_node.release(); which kind of clutters up what would have been a single line of code if I wasn't worrying about exception safety and a memory leak. (Actually I was wondering if I could post my whole code sample (about 300 lines) and ask people to critique it for idiomatic C++ usage in general, but I'm not sure whether that kind of question is appropriate on stackoverflow.)

  • Parallel processing via multithreading in Java

    - by Robz
    There are certain algorithms whose running time can decrease significantly when one divides up a task and gets each part done in parallel. One of these algorithms is merge sort, where a list is divided into infinitesimally smaller parts and then recombined in a sorted order. I decided to do an experiment to test whether or not I could I increase the speed of this sort by using multiple threads. I am running the following functions in Java on a Quad-Core Dell with Windows Vista. One function (the control case) is simply recursive: // x is an array of N elements in random order public int[] mergeSort(int[] x) { if (x.length == 1) return x; // Dividing the array in half int[] a = new int[x.length/2]; int[] b = new int[x.length/2+((x.length%2 == 1)?1:0)]; for(int i = 0; i < x.length/2; i++) a[i] = x[i]; for(int i = 0; i < x.length/2+((x.length%2 == 1)?1:0); i++) b[i] = x[i+x.length/2]; // Sending them off to continue being divided mergeSort(a); mergeSort(b); // Recombining the two arrays int ia = 0, ib = 0, i = 0; while(ia != a.length || ib != b.length) { if (ia == a.length) { x[i] = b[ib]; ib++; } else if (ib == b.length) { x[i] = a[ia]; ia++; } else if (a[ia] < b[ib]) { x[i] = a[ia]; ia++; } else { x[i] = b[ib]; ib++; } i++; } return x; } The other is in the 'run' function of a class that extends thread, and recursively creates two new threads each time it is called: public class Merger extends Thread { int[] x; boolean finished; public Merger(int[] x) { this.x = x; } public void run() { if (x.length == 1) { finished = true; return; } // Divide the array in half int[] a = new int[x.length/2]; int[] b = new int[x.length/2+((x.length%2 == 1)?1:0)]; for(int i = 0; i < x.length/2; i++) a[i] = x[i]; for(int i = 0; i < x.length/2+((x.length%2 == 1)?1:0); i++) b[i] = x[i+x.length/2]; // Begin two threads to continue to divide the array Merger ma = new Merger(a); ma.run(); Merger mb = new Merger(b); mb.run(); // Wait for the two other threads to finish while(!ma.finished || !mb.finished) ; // Recombine the two arrays int ia = 0, ib = 0, i = 0; while(ia != a.length || ib != b.length) { if (ia == a.length) { x[i] = b[ib]; ib++; } else if (ib == b.length) { x[i] = a[ia]; ia++; } else if (a[ia] < b[ib]) { x[i] = a[ia]; ia++; } else { x[i] = b[ib]; ib++; } i++; } finished = true; } } It turns out that function that does not use multithreading actually runs faster. Why? Does the operating system and the java virtual machine not "communicate" effectively enough to place the different threads on different cores? Or am I missing something obvious?

  • HTML5 Video Tag in Chrome - Why is currentTime ignored when video downloaded from my webserver?

    - by larson4
    I want to be able to play back video from a specific time using the HTML5 video tag (and currently only need to worry about Chrome). This is possible by setting the currentTime property of a video element. That works fine in Chrome with a video sourced from html5rocks.com, but is ignored when the same file is loaded from my own local webserver. Using the sample code from http://playground.html5rocks.com/#video_tag, I have arrived at the following HTML: <!DOCTYPE html> <html> <body> <video id="video1" width="320" height="240" volume=".7" controls preload=true autobuffer> <source src="http://playground.html5rocks.com/samples/html5_misc/chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> </video> <input type=button onclick="play()" value="play"> <input type=button onclick="setTime()" value="setTime"> <input type=button onclick="pause()" value="pause"> <script> var play=function() { document.getElementById("video1").play(); } var setTime=function() { document.getElementById("video1").currentTime=2; } var pause=function() { document.getElementById("video1").pause(); } </script> </body> </html> Using Chrome, if you Wait for the video to download for a bit (until the progress bar is about 10% in) Press setTime - you should notice the time jump to 2 seconds press play ...the video will start at 2 seconds in. But if I download the webm file in the source src to my local webserver, and change src to point locally: <source src="chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> ...then setting currentTime is complete ignored. No errors are showing in the developer tools console. Now, my webserver is serving this with mime type "video/webm", but it will be served like any old file -- not streamed. Do I need a webserver that streams in some specific way? What else could be at fault here? Note: The webserver is a proprietary platform and won't have any of the same exact settings or controls one might expect of Tomcat or some other commonly used webserver, though there may be other ways to achieve the same effect.

  • iPhone RSS thumbnail

    I have a simple RSS reader. Stories are downloaded, put into a UITableView, and when you click it, each story loads in a UIWebView. It works great. Now though, I'd like to incorporate an image on the left side (like you'd see in the YouTube app). However, since my app pulls from an RSS feed, I can't simply specify image X to appear in row X because row X will be row Y tomorrow, and things will get out of order, you know? I am currently pulling from a YouTube RSS feed, and can get the video title, description, publication date, but I'm stuck as to how to pull the little thumbnail besides each entry in the feed. As you can probably tell, I'm a coding newbie (this being my first application other than a Hello World app) and I'm getting so frustrated by my own lack of knowledge. Thanks! BTW, here's some sample code: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ //NSLog(@"found this element: %@", elementName); if (currentElement) { [currentElement release]; currentElement = nil; } currentElement = [elementName copy]; if ([elementName isEqualToString:@"item"]) { // clear out our story item caches... item = [[NSMutableDictionary alloc] init]; currentTitle = [[NSMutableString alloc] init]; currentDate = [[NSMutableString alloc] init]; currentSummary = [[NSMutableString alloc] init]; currentLink = [[NSMutableString alloc] init]; } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{ //NSLog(@"ended element: %@", elementName); if ([elementName isEqualToString:@"item"]) { // save values to an item, then store that item into the array... [item setObject:currentTitle forKey:@"title"]; [item setObject:currentLink forKey:@"link"]; [item setObject:currentSummary forKey:@"summary"]; [item setObject:currentDate forKey:@"date"]; [stories addObject:[item copy]]; NSLog(@"adding story: %@", currentTitle); } } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{ //NSLog(@"found characters: %@", string); // save the characters for the current item... if ([currentElement isEqualToString:@"title"]) { [currentTitle appendString:string]; } else if ([currentElement isEqualToString:@"link"]) { [currentLink appendString:string]; } else if ([currentElement isEqualToString:@"description"]) { [currentSummary appendString:string]; } else if ([currentElement isEqualToString:@"pubDate"]) { [currentDate appendString:string]; } }

  • JQuery Menu plugins under ASP.NET MVC seem to only work in Chrome, but not in IE & FireFox

    - by Antony
    Recently, I was trying to prototype some jQuery-based menu into ASP.NET MVC. Just to name two examples here: plugins.jquery.com/project/columnview www.filamentgroup.com/lab/jquery_ipod_style_and_flyout_menus/ Their demo page looks great, but when I integrate their sample code into MVC, the script no longer works in IE and FireFox, but it seems to work just fine under Google Chrome. Can someone kindly enough to point out what I missed? I will be honest here. I am still new to JavaScript, so it is still a learning phase to me, so any help is highly appreciated. I have placed a copy of my VS2010 solution zip file @ http://db.tt/0UNDkN Here is what I did. In the Site.Master, I have something like <body> <div class="page">{truncated...}</div> <script src="http://code.jquery.com/jquery-1.4.2.min.js" type="text/javascript" charset="utf-8"></script> <asp:ContentPlaceHolder ID="ScriptContent" runat="server" /> </body> And inside View file, I have the following <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <div id="original"> {some demo block, copied from javascript demo} </div> </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="ScriptContent" runat="server"> <script type="text/javascript" src="<%= Url.Content("~/Scripts/jquery.columnview.js") %>" /> <script type="text/javascript"> $(document).ready(function () { $('#original').columnview(); }); </script> </asp:Content> Compiled the code and ran it under IE. Ideally, it should work like the demo in www.christianyates.com/blog/jquery/finder-column-view-hierarchical-lists-jquery, but in reality, it only displays unordered list in plain view. (If you download the solution file and run it, you should be able to repro this as well). Next, tried with FireFox, not working either, same result as IE. Finally, when I try it under Google Chrome 4.1 (lastest version), and the script displays just fine. Really puzzling here :-/ Thank you for reading :D

  • Virtual member call in a constructor when assigning value to property

    - by comecme
    I have an Abstract class and a Derived class. The abstract class defines an abstract property named Message. In the derived class, the property is implemented by overriding the abstract property. The constructor of the derived class takes a string argument and assigns it to its Message property. In Resharper, this assignment leads to a warning "Virtual member call in constructor". The AbstractClass has this definition: public abstract class AbstractClass { public abstract string Message { get; set; } protected AbstractClass() { } public abstract void PrintMessage(); } And the DerivedClass is as follows: using System; public class DerivedClass : AbstractClass { private string _message; public override string Message { get { return _message; } set { _message = value; } } public DerivedClass(string message) { Message = message; // Warning: Virtual member call in a constructor } public DerivedClass() : this("Default DerivedClass message") {} public override void PrintMessage() { Console.WriteLine("DerivedClass PrintMessage(): " + Message); } } I did find some other questions about this warning, but in those situations there is an actual call to a method. For instance, in this question, the answer by Matt Howels contains some sample code. I'll repeat it here for easy reference. class Parent { public Parent() { DoSomething(); } protected virtual void DoSomething() {}; } class Child : Parent { private string foo; public Child() { foo = "HELLO"; } protected override void DoSomething() { Console.WriteLine(foo.ToLower()); } } Matt doesn't describe on what error the warning would appear, but I'm assuming it will be on the call to DoSomething in the Parent constructor. In this example, I understand what is meant by a virtual member being called. The member call occurs in the base class, in which only a virtual method exists. In my situation however, I don't see why assigning a value to Message would be calling a virtual member. Both the call to and the implementation of the Message property are defined in the derived class. Although I can get rid of the error by making my Derived Class sealed, I would like to understand why this situation is resulting in the warning.

  • Decentralized synchronized secure data storage

    - by Alberich
    Introduction Hi, I am going to ask a question which seems utopic for me, but I need to know if there is a way to achieve what I need. And if not, I need to know why not. The idea Suppose I have a database structure, in MySql. I want to create some solution to allow anyone (no matter who, no matter where) to have a synchronized copy (updated clone) of this database (with its content) Well, and it is not going to be just one synchronized copy, it could (and should) be a multiple replication (supposing the basic, this means, for example, ten copies all over the world) And, the most important thing: It must be secure. By secure I mean only real-accepted transactions will be synchronized with all the others (no matter how many) database copies/clones. Note: Since it would be quite difficult to make the synchronization in real-time, I will design everything to make this feature dispensable. So it is not required. My auto-suggestion This is how I am thinking to manage it: Time identifiers and Updates checking: Every action (insert, update, delete...) will be stored as the action instruction itself, associated to the time identifier. [I think better than a DATETIME field, it'll be an INT one, with the number of miliseconds passed from 1st january 2013 on, for example]. So each copy is going to ask to the "neighbour copy" for new actions done since last update, and execute them after checking they are allowed. Problem 1: the "neighbour copy" could be outdated too. Solution 1: do not ask just one neighbour, create a random list with some of the copies/clones and ask them for news (I could avoid the list and ask ALL the clones for updates, but this will be inefficient if clones number ascends too much). Problem 2: Real-time global synchronization is not active. What if... Someone at CLONE_ENTERPRISING inserts a row into TABLE. ... this row goes to every clone ... Someone at CLONE_FIXEMALL deletes this row. ... and at the same time, somewhere in an outdated clone ... Someone at CLONE_DROPOUT edits this row (now inexistent at the other clones) Solution 2: easy stuff, force a GLOBAL synchronization before doing any new "depending-on-third-data action" (edit, for example). This global synch. will be unnecessary when making an INSERT, for instance. Note: Well, someone could have some fun, and make the same insert in two clones... since they're not getting updated in real-time, this row will exist twice. But, it's the same as when we have one single database, in some needed cases we check if there is an existing same-row before doing the final action. Not a problem. Problem 3: It is possible to edit the code and do not filter actions, so someone could spread instructions to delete everything, or just make some trolling activity. This is not a problem, since good clones will always be somewhere. Those who got bad won't interest anymore. I really appreciate if you read. I know this is not the perfect solution, it has possibly hundred of holes, but it is my basic start. I will now appreciate anything you can teach me now. Thanks a lot. PS.: It could be that all this I am trying already exists and has its own name. Sorry for asking then (I'd anyway thank this name, if it exists)

  • Recommended integration mechanism for bi-directional, authenticated, encrypted connection in C clien

    - by rcampbell
    Let me first give an example. Imagine you have a single server running a JVM application. This server keeps a collection of N equations, once for each client: Client #1: 2x Client #2: 1 + y Client #3: z/4 This server includes an HTTP interface so that random visitors can type https://www.acme.com/client/3 int their browsers and see the latest evaluated result of z/4. The tricky part is that either the client or the server may change the variable value at any time, informing the other party immediately. More specifically, Client #3 - a C app - can initially tell the server that z = 20. An hour later that same client informs the server that z = 23. Likewise the server can later inform the client that z = 28. As caf pointed out in the comments, there can be a race condition when values are changed by the client and server simultaneously. The solution would be for both client and server to send the operation performed in their message, which would need to be executed by the other party. To keep things simple, let's limit the operations to (commutative) addition, allowing us to disregard message ordering. For example, the client seeds the server with z = 20: server:z=20, client:z=20 server sends {+3} message (so z=23 locally) & client sends {-2} message (so z=18 locally) at the exact same time server receives {-2} message at some point, adds to his local copy so z=21 client receives {+3} message at some point, adds to his local copy so z=21 As long as all messages are eventually evaluated by both parties, the correct answer will eventually be given to the users of the client and server since we limited ourselves to commutative operations (addition of 3 and -2). This does mean that both client and server can be returning incorrect answers in the time it takes for messages to be exchanged and processed. While undesirable, I believe this is unavoidable. Some possible implementations of this idea include: Open an encrypted, always on TCP socket connection for communication Pros: no additional infrastructure needed, client and server know immediately if there is a problem (disconnect) with the other party, fairly straightforward (except the the encryption), native support from both JVM and C platforms Cons: pretty low-level so you end up writing a lot yourself (protocol, delivery verification, retry-on-failure logic), probably have a lot of firewall headaches during client app installation Asynchronous messaging (ex: ActiveMQ) Pros: transactional, both C & Java integration, free up the client and server apps from needing retry logic or delivery verification, pretty straightforward encryption, easy extensibility via message filters/routers/etc Cons: need additional infrastructure (message server) which must never fail, Database or file system as asynchronous integration point Same pros/cons as above but messier RESTful Web Service Pros: simple, possible reuse of the server's existing REST API, SSL figures out the encryption problem for you (maybe use RSA key a la GitHub for authentication?) Cons: Client now needs to run a C HTTP REST server w/SSL, client and server need retry logic. Axis2 has both a Java and C version, but you may be limited to SOAP. What other techniques should I be evaluating? What real world experiences have you had with these mechanisms? Which do you recommend for this problem and why?

  • Public class: The best way to store and access NSMutableDictionary?

    - by meridimus
    I have a class to help me store persistent data across sessions. The problem is I want to store a running sample of the property list or "plist" file in an NSMutableArray throughout the instance of the Persistance class so I can read and edit the values and write them back when I need to. The problem is, as the methods are publicly defined I cannot seem to access the declared NSMutableDictionary without errors. The particular error I get on compilation is: warning: 'Persistence' may not respond to '+saveData' So it kind of renders my entire process unusable until I work out this problem. Here is my full persistence class (please note, it's unfinished so it's just to show this problem): Persistence.h #import <UIKit/UIKit.h> #define kSaveFilename @"saveData.plist" @interface Persistence : NSObject { NSMutableDictionary *saveData; } @property (nonatomic, retain) NSMutableDictionary *saveData; + (NSString *)dataFilePath; + (NSDictionary *)getSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level; + (void)writeSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level withData:(NSDictionary *)saveData; + (NSString *)makeCampaign:(NSUInteger)campaign andLevelKey:(NSUInteger)level; @end Persistence.m #import "Persistence.h" @implementation Persistence @synthesize saveData; + (NSString *)dataFilePath { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:kSaveFilename]; } + (NSDictionary *)getSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level { NSString *filePath = [self dataFilePath]; if([[NSFileManager defaultManager] fileExistsAtPath:filePath]) { NSLog(@"File found"); [[self saveData] setDictionary:[[NSDictionary alloc] initWithContentsOfFile:filePath]]; // This is where the warning "warning: 'Persistence' may not respond to '+saveData'" occurs NSString *campaignAndLevelKey = [self makeCampaign:campaign andLevelKey:level]; NSDictionary *campaignAndLevelData = [[self saveData] objectForKey:campaignAndLevelKey]; return campaignAndLevelData; } else { return nil; } } + (void)writeSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level withData:(NSDictionary *)saveData { NSString *campaignAndLevelKey = [self makeCampaign:campaign andLevelKey:level]; NSDictionary *saveDataWithKey = [[NSDictionary alloc] initWithObjectsAndKeys:saveData, campaignAndLevelKey, nil]; //[campaignAndLevelKey release]; [saveDataWithKey writeToFile:[self dataFilePath] atomically:YES]; } + (NSString *)makeCampaign:(NSUInteger)campaign andLevelKey:(NSUInteger)level { return [[NSString stringWithFormat:@"%d - ", campaign+1] stringByAppendingString:[NSString stringWithFormat:@"%d", level+1]]; } @end I call this class like any other, by including the header file in my desired location: @import "Persistence.h" Then I call the function itself like so: NSDictionary *tempSaveData = [[NSDictionary alloc] [Persistence getSaveWithCampaign:currentCampaign andLevel:currentLevel]];

  • how to filter data from xml file for displaying only selected as nodes in treeview

    - by michale
    I have an xml file named "books.xml" provided in the link "http://msdn.microsoft.com/en-us/library/windows/desktop/ms762271(v=vs.85).aspx". What my requirement was to disaplay only the <title> from xml information as nodes in tree view. But when i did the following coding its displaying all the values as nodes like "catalog" as rootnode, book as parent node for all then author,title,genre etc as nodes but i want only root node catalogue and title as nodes not even book. Can any body guide me what modification i need to do in the exisitng logic for displaying title as nodes OpenFileDialog dlg = new OpenFileDialog(); dlg.Title = "Open XML document"; dlg.Filter = "XML Files (*.xml)|*.xml"; dlg.FileName = Application.StartupPath + "\\..\\..\\Sample.xml"; if (dlg.ShowDialog() == DialogResult.OK) { try { //Just a good practice -- change the cursor to a //wait cursor while the nodes populate this.Cursor = Cursors.WaitCursor; //First, we'll load the Xml document XmlDocument xDoc = new XmlDocument(); xDoc.Load(dlg.FileName); //Now, clear out the treeview, //and add the first (root) node treeView1.Nodes.Clear(); treeView1.Nodes.Add(new TreeNode(xDoc.DocumentElement.Name)); TreeNode tNode = new TreeNode(); tNode = (TreeNode)treeView1.Nodes[0]; //We make a call to addTreeNode, //where we'll add all of our nodes addTreeNode(xDoc.DocumentElement, tNode); //Expand the treeview to show all nodes treeView1.ExpandAll(); } catch (XmlException xExc) //Exception is thrown is there is an error in the Xml { MessageBox.Show(xExc.Message); } catch (Exception ex) //General exception { MessageBox.Show(ex.Message); } finally { this.Cursor = Cursors.Default; //Change the cursor back } }} //This function is called recursively until all nodes are loaded private void addTreeNode(XmlNode xmlNode, TreeNode treeNode) { XmlNode xNode; TreeNode tNode; XmlNodeList xNodeList; if (xmlNode.HasChildNodes) //The current node has children { xNodeList = xmlNode.ChildNodes; for (int x = 0; x <= xNodeList.Count - 1; x++) //Loop through the child nodes { xNode = xmlNode.ChildNodes[x]; treeNode.Nodes.Add(new TreeNode(xNode.Name)); tNode = treeNode.Nodes[x]; addTreeNode(xNode, tNode); } } else //No children, so add the outer xml (trimming off whitespace) treeNode.Text = xmlNode.OuterXml.Trim(); }

  • XSD: xs:sequence & xs:choice combination for xs:extension elements?

    - by bguiz
    Hi, My question is about defining an XML schema that will validate the following sample XML: <rules> <other>...</other> <bool>...</bool> <other>...</other> <string>...</string> <other>...</other> </rules> The order of the child nodes does not matter. The cardinality of the child nodes is 0..unbounded. All the child elements of the rules node have a common base type, rule, like so: <xs:complexType name="booleanRule"> <xs:complexContent> <xs:extension base="rule"> ... </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="stringFilterRule"> <xs:complexContent> <xs:extension base="filterRule"> ... </xs:extension> </xs:complexContent> </xs:complexType> My current attempt at defining the schema for the rules node is below. However, Can I nest xs:choice within xs:sequence? If, where do I specify the maxOccurs="unbounded" attribute? Is there a better way to do this, such as an xs:sequence which specifies only the base type of its child elements? <xs:element name="rules"> <xs:complexType> <xs:sequence> <xs:choice> <xs:element name="bool" type="booleanRule" /> <xs:element name="string" type="stringRule" /> <xs:element name="other" type="someOtherRule" /> </xs:choice> </xs:sequence> </xs:complexType> </xs:element>

  • Why does this Quicksort work?

    - by IVlad
    I find this Quicksort partitioning approach confusing and wrong, yet it seems to work. I am referring to this pseudocode. Note: they also have a C implementation at the end of the article, but it's very different from their pseudocode, so I don't care about that. I have also written it in C like this, trying to stay true to the pseudocode as much as possible, even if that means doing some weird C stuff: #include <stdio.h> int partition(int a[], int p, int r) { int x = a[p]; int i = p - 1; int j = r + 1; while (1) { do j = j - 1; while (!(a[j] <= x)); do i = i + 1; while (!(a[i] >= x)); if (i < j) { int t = a[i]; a[i] = a[j]; a[j] = t; } else { for (i = 1; i <= a[0]; ++i) printf("%d ", a[i]); printf("- %d\n", j); return j; } } } int main() { int a[100] = //{8, 6,10,13,15,8,3,2,12}; {7, 7, 6, 2, 3, 8, 4, 1}; partition(a, 1, a[0]); return 0; } If you run this, you'll get the following output: 1 6 2 3 4 8 7 - 5 However, this is wrong, isn't it? Clearly a[5] does not have all the values before it lower than it, since a[2] = 6 > a[5] = 4. Not to mention that 7 is supposed to be the pivot (the initial a[p]) and yet its position is both incorrect and lost. The following partition algorithm is taken from wikipedia: int partition2(int a[], int p, int r) { int x = a[r]; int store = p; for (int i = p; i < r; ++i) { if (a[i] <= x) { int t = a[i]; a[i] = a[store]; a[store] = t; ++store; } } int t = a[r]; a[r] = a[store]; a[store] = t; for (int i = 1; i <= a[0]; ++i) printf("%d ", a[i]); printf("- %d\n", store); return store; } And produces this output: 1 6 2 3 8 4 7 - 1 Which is a correct result in my opinion: the pivot (a[r] = a[7]) has reached its final position. However, if I use the initial partitioning function in the following algorithm: void Quicksort(int a[], int p, int r) { if (p < r) { int q = partition(a, p, r); // initial partitioning function Quicksort(a, p, q); Quicksort(a, q + 1, r); // I'm pretty sure q + r was a typo, it doesn't work with q + r. } } ... it seems to be a correct sorting algorithm. I tested it out on a lot of random inputs, including all 0-1 arrays of length 20. I have also tried using this partition function for a selection algorithm, in which it failed to produce correct results. It seems to work and it's even very fast as part of the quicksort algorithm however. So my questions are: Can anyone post an example on which the algorithm DOESN'T work? If not, why does it work, since the partitioning part seems to be wrong? Is this another partitioning approach that I don't know about?

[00 05, 00 0a, 00 13, 00 04, 00 02, 00 ff] - [RC4, PBE-MD5-DES, RSA, MD5, PKCS, ???] [01 00] Null compression method The as400 server responds back with: 15 03 00 00 02 02 28 [15] SSL3_RT_ALERT [03 00] SSL Version [00 02] Body Length (2 Bytes) [02 28] 2 = SSL3_RT_FATAL, 40 = SSL3_AD_HANDSHAKE_FAILURE I'm specifically looking to decode the '00 FF' at the end of the cyphers. Have I decoded it correctly? What does, if anything, '00 FF' decode too? I am using the following code to test/reproduce: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net.Sockets; using System.Net.Security; using System.Security.Authentication; using System.IO; using System.Diagnostics; using System.Security.Cryptography.X509Certificates; namespace TestSslStreamApp { class DebugStream : Stream { private Stream AggregatedStream { get; set; } public DebugStream(Stream stream) { AggregatedStream = stream; } public override bool CanRead { get { return AggregatedStream.CanRead; } } public override bool CanSeek { get { return AggregatedStream.CanSeek; } } public override bool CanWrite { get { return AggregatedStream.CanWrite; } } public override void Flush() { AggregatedStream.Flush(); } public override long Length { get { return AggregatedStream.Length; } } public override long Position { get { return AggregatedStream.Position; } set { AggregatedStream.Position = value; } } public override int Read(byte[] buffer, int offset, int count) { int bytesRead = AggregatedStream.Read(buffer, offset, count); return bytesRead; } public override long Seek(long offset, SeekOrigin origin) { return AggregatedStream.Seek(offset, origin); } public override void SetLength(long value) { AggregatedStream.SetLength(value); } public override void Write(byte[] buffer, int offset, int count) { AggregatedStream.Write(buffer, offset, count); } } class Program { static void Main(string[] args) { const string HostName = "as400"; TcpClient tcpClient = new TcpClient(HostName, 992); SslStream sslStream = new SslStream(new DebugStream(tcpClient.GetStream()), false, null, null, EncryptionPolicy.AllowNoEncryption); sslStream.AuthenticateAsClient(HostName, null, SslProtocols.Ssl3, false); } } }
