  • Why does this XSL fails to retrieve value from xml ?

    - by Pavitar
    Following is an extract of the XSL stylesheet that I have written. It says my '.xsl' is well formed but it somehow does not retrieve values from the xml,instead jus pastes the header and table headings. EDIT <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:template match="/" > <html> <head> <title>GlenMark Pharma</title> </head> <h1 align="center"><font face="Monotype Corsiva" color="red">GlenMarkPharma</font></h1> <body> <table> <tbody> <tr> <th>ID</th> <th>ENAME</th> <th>Mobile</th> <th>EMAIL</th> <th>PWD</th> </tr> <xsl:for-each select="employees/employee"> <tr> <td><xsl:value-of select="@empID" /></td> <td><xsl:value-of select="name" /></td> <td><xsl:value-of select="mobile" /></td> <td><xsl:value-of select="email" /></td> <td><xsl:value-of select="pwd" /></td> </tr> </xsl:for-each> </tbody> </table> </body> </html> </xsl:template> </xsl:stylesheet> Here is my XML doc: <?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type="text/xsl" href="MyfirstXsl.xsl"?> <!DOCTYPE employees SYSTEM "Mydtd.dtd"> <me:employees xmlns:me="[email protected]" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="[email protected] Mycomplex.xsd"> <me:employee empID="EMP101"> <me:name>Vicky</me:name> <me:mobile>9870582356</me:mobile> <me:email>[email protected]</me:email> <me:pwd>&defPWD;</me:pwd> </me:employee> </me:employees> I have also tried writing: <xsl:for-each select="employees/employee"> <tr> <td><xsl:value-of select="@empID" /></td> <td><xsl:value-of select="me:name" /></td> in the XSL since I have an alias to the namespace in my XML Doc.But it gives me an error of Invalid Pre-fix.I don't know what I'm doing wrong.

  • Search Form in Responsive Design - Remove Search button on Mobile

    - by Kevin
    I'm working with a search box in the header of a responsive website. On desktop/tablet widths, there's a search input field and a styled 'search' button to the right. You can type in a search term and either click 'SEARCH' button or just hit enter on the keyboard with the same result. When you scale down to mobile widths, the search input field fills the width of the screen. The submit button falls below it. On a desktop, clicking the button or hitting enter activate the search. On an actual iphone phone, you can hit the 'SEARCH' button, but the native mobile keyboard that rises from the bottom of the screen has a search button where the enter/return key would normally be. It seems to know I'm in a form and the keyboard automatically gives me the option to kick off the search by basically hitting the ENTER key location....but it says SEARCH. So far so good. I figure I don't need the button in the header on mobile since it's already in the keyboard. Therefore, I'll hide the button on mobile widths and everything will be tighter and look better. So I added this to my CSS to hide it in mobile: #search-button {display: none;} But now the search doesn't work at all. On mobile, I don't get the option in the keyboard that showed up before and if I just hit enter, it doesn't work at all. On desktop at mobile width, hitting enter also not longer works. So clearly by hiding the submit/search button, the phone no longer gave me the native option to run the search. In addition, on the desktop at mobile width, even hitting enter inside the search input box also fails to launch the the search. Here's my search box: <form id="search-form" method="get" accept-charset="UTF-8, utf-8" action="search.php"> <fieldset> <div id="search-wrapper"> <label id="search-label" for="search">Item:</label> <input id="search" class="placeholder-color" name="item" type="text" placeholder="Item Number or Description" /> <button id="search-button" title="Go" type="submit"><span class="search-icon"></span></button> </div> </fieldset> </form> Here's what my CSS looks like: #search-wrapper { float: left; display: inline-block; position: relative; white-space: nowrap; } #search-button { display: inline-block; cursor: pointer; vertical-align: top; height: 30px; width: 40px; } @media only screen and (max-width: 639px) { #search-wrapper { display: block; margin-bottom: 7px; } #search-button { /* this didn't work....it hid the button but the search failed to load */ display: none;*/ } } So.....how can I hide this submit button when I'm on a mobile screen, but still let the search run from the mobile keyboard or just run by hitting enter when in the search input box. I was sure that putting display:none on the search button at mobile width would do the trick, but apparently not. Thanks...

  • PHP Image resize - Why is the image uploaded but not resized?

    - by Hans
    BACKGROUND I have a script to upload an image. One to keep the original image and one to resize the image. 1. If the image dimensions (width & height) are within max dimensions I use a simple "copy" direct to folder UserPics. 2. If the original dimensions are bigger than max dimensions I want to resize the width and height to be within max. Both of them are uploading the image to the folder, but in case 2, the image will not be resized. QUESTION Is there something wrong with the script? Is there something wrong with the settings? SETTINGS Server: WAMP 2.0 PHP: 5.3.0 PHP.ini: GD2 enabled, Memory=128M (have tried 1000M) Tried imagetypes uploaded: jpg, jpeg, gif, and png (same result for all of them) SCRIPT //Uploaded image $filename = stripslashes($_FILES['file']['name']); //Read filetype $i = strrpos($filename,"."); if (!$i) { return ""; } $l = strlen($filename) - $i; $extension = substr($filename,$i+1,$l); $extension = strtolower($extension); //New picture name = maxid+1 (from database) $query = mysql_query("SELECT MAX(PicId) AS number FROM userpictures"); $row = mysql_fetch_array($query); $imagenumber = $row['number']+1; //New name of image (including path) $image_name=$imagenumber.'.'.$extension; $newname = "UserPics/".$image_name; //Check width and height of uploaded image list($width,$height)=getimagesize($uploadedfile); //Check memory to hold this image (added only as checkup) $imageInfo = getimagesize($uploadedfile); $requiredMemoryMB = ( $imageInfo[0] * $imageInfo[1] * ($imageInfo['bits'] / 8) * $imageInfo['channels'] * 2.5 ) / 1024; echo $requiredMemoryMB."<br>"; //Max dimensions that can be uploaded $maxwidth = 20; $maxheight = 20; // Check if dimensions shall be original if ($width > $maxwidth || $height > $maxheight) { //Make jpeg from uploaded image if ($extension=="jpg" || $extension=="jpeg" || $extension=="pjpeg" ) { $modifiedimage = imagecreatefromjpeg($uploadedfile); } elseif ($extension=="png") { $modifiedimage = imagecreatefrompng($uploadedfile); } elseif ($extension=="gif") { $modifiedimage = imagecreatefromgif($uploadedfile); } //Change dimensions if ($width > $height) { $newwidth = $maxwidth; $newheight = ($height/$width)*$newwidth; } else { $newheight = $maxheight; $newwidth = ($width/$height)*$newheight; } //Create new image with new dimensions $newdim = imagecreatetruecolor($newwidth,$newheight); imagecopyresized($newdim,$modifiedimage,0,0,0,0,$newwidth,$newheight,$width,$height); imagejpeg($modifiedimage,$newname,60); // Remove temp images imagedestroy($modifiedimage); imagedestroy($newdim); } else { // Just add picture to folder without resize (if org dim < max dim) $newwidth = $width; $newheight = $height; $copied = copy($_FILES['file']['tmp_name'], $newname); } //Add image information to the MySQL database mysql_query("SET character_set_connection=utf8", $dbh); mysql_query("INSERT INTO userpictures (PicId, Picext, UserId, Width, Height, Size) VALUES('$imagenumber', '$extension', '$_SESSION[userid]', '$newwidth', '$newheight', $size)")

  • Trouble with datasource not being called from viewWillAppear

    - by user278859
    A little background. I have taken GCCalendar which only works in portrait orientation and extended it to work in landscape similar to how the iPhone's Calendar app works. I did this by duplicating the main view class and modifying it to work in landscape. So when the phone is in portrait orientation the CGCalendar is instantiated from the apps main view controller using the original portrait view class and when in landscape orientation using the new modified landscape view class. Most of the other classes in GCCalendar are shared without modification. A few had to be duplicated as well. I got it all working great except for an issue with the datasource. The datasource is called when the calendar is first loaded and each time the user changes the dates being viewed. Problem is I can't get the datasource call to work on the first call. I am stumped as it works fine in portrait orientation and I cannot find any difference between the 2 versions. Following is some of the code that shows how it gets to the datasource call the first time. Subsequent calls removes all the calendar subviews and instantiates them again with the new dates. The duplicated landscape class names end in LS. Otherwise as you can see they are identical. Does anyone has any idea of where else I might look to resolve this issue? Thanks, John -------------------------------- //App main view controller - (void)showLandscapeCalendar { GCCalendarLandscapeView *calendar = [[[GCCalendarLandscapeView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (void)showPortraitCalendar { GCCalendarPortraitView *calendar = [[[GCCalendarPortraitView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (NSArray *)calendarEventsForDate:(NSDate *)date{ //build and return the events array //this is the protocol datasource method //It is supposed to run every time the date changes in the calendar } ------------------------------- // GCCalendarLandscapeView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayViewLS *nextDayView = [[GCCalendarDayViewLS alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayViewLS - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { //** first time through the dataSource method does not run events = [dataSource calendarEventsForDate:date]; } ------------------------------- // GCCalendarPortraitView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayView *nextDayView = [[GCCalendarDayView alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayView - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { **//this one works every time events = [dataSource calendarEventsForDate:date]; }

  • How to notify client about updated UpdatePanel content on server side

    - by csh1981
    I have a problem with UpdatePanel.Update() which works initially but then stops. I have tumbled with this problem for some time and some background is needed so please read ahead. I have an ASP.net application in which I have a subpage that display computed information in graphs. Each graph is embedded in an UpdatePanel. The graph is a user control that uses the standard asp:Chart for display. My task is to enable this page with AJAX capabilities so the page is responsive during postbacks. When I access this page from another page, during the initial page rendering, I use a wait dialog for each graph and a pageload event on the client side. In the client event, a hidden button is clicked which a server event handles (the hidden button is inside an UpdatePanel so the postback is asynchronous). Each graph is computed and the UpdatePanels are in turn updated with the Chart content. This is done using UpdatePanel.Update. And it is successful. However, I also have some RadioButtons on the page. These are dynamically created. The purpose of them is to switch graph type --- to show the same data in a different way. Same type of time consuming computation is needed in order to do so. I subscribe on each RadioButton's OnCheckedChanged event and the postback is asynchronous since the radiobuttons are inside an UpdatePanel. In the server event handler I determine the type of graph and use this as an input to the Chart control. I then remove the old Chart control from my Panel and adds new Chart and then I call UpdatePanel.Update(). But with no success. Nothing happens, no errors, nothing. Why is this?? I think this is strange because if I compute every Chart data in the initial rendering instead of using the "Wait dialog"-solution described earlier then I can select graph types successfully and all subsequent AJAX requests work as intended. Also, the same code (computing the chart, removal, and adding the Chart control to Panel and UpdatePanel.Update()) is hit during the initial rendering of the page, and it works only the first time. Here is the method that computes the graph and adds it to the panel and update the UpdatePanel: public void UpdateGraph(GraphType type, GraphMapper mapper) { //Panel is the content of UpdatePanelGraph's Panel.Controls.Clear(); chart = new Chart(type, mapper); //Computation happens inside here panel.Controls.Add(chart); //UpdatePanelGraph is in UpdateMode Conditional and has //ChildrenAsTriggers set to false UpdatePanelGraph.Update(); } I really need a way for these radiobuttons to work, possible using some clientside JavaScript or another way of handling things on the server side. I have thought about using a JavaScript postback call on the UpdatePanel instead of the UpdatePanel.Update(). However, the issue I have here is how to notify the client side when the server side is finished with computing the graph? An plausible explanation of the strange behavior is also much appreciated. Any help appreciated, thanks

  • ASP.NET GridView - Cannot set the colour of the row during databind?

    - by Dan
    This is driving me NUTS! It's something that I've done 100s of time with a Datagrid. I'm now using a Gridview and I can't figure this out. I've got this grid: <asp:GridView AutoGenerateColumns="false" runat="server" ID="gvSelect" CssClass="GridViewStyle" GridLines="None" ShowHeader="False" PageSize="20" AllowPaging="True"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:Label runat="server" ID="lbldas" Text="blahblah"></asp:Label> </ItemTemplate> </asp:TemplateField> </Columns> And during the RowDataBound I've tried: Protected Sub gvSelect_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvSelect.RowCreated If e.Row.RowType = DataControlRowType.DataRow Then e.Row.Attributes.Add("onMouseOver", "this.style.backgroundColor='lightgrey'") End If End Sub And it NEVER sets the row backcolor.. I've been successful in using: gridrow.Cells(0).BackColor = Drawing.Color.Blue But doing the entire row? NOPE! and it's driving me nuts.. does ANYONE have solution for me? And just for fun I put this on the SAME page: <asp:DataGrid AutoGenerateColumns="false" runat="server" ID="dgSelect" GridLines="None" ShowHeader="False" PageSize="20" AllowPaging="True"> <Columns> <asp:TemplateColumn> <ItemTemplate> <asp:Label runat="server" ID="lbldas" Text="blahblah"></asp:Label> </ItemTemplate> </asp:TemplateColumn> </Columns> </asp:DataGrid> And in the ItemDataBound I put: If Not e.Item.ItemType = ListItemType.Header And Not e.Item.ItemType = ListItemType.Footer Then e.Item.Attributes.Add("onMouseOver", "this.style.backgroundColor='lightgrey'") End If And it works as expected.. SO What am I doing wrong with the Gridview? UPDATE ************** I thought I'd post the resulting HTML to show that any styles aren't affecting this. Here's the gridview html: <div class="AspNet-GridView" id="gvSelect"> <table cellpadding="0" cellspacing="0" summary=""> <tbody> <tr> <td> <span id="gvSelect_ctl02_lbldas">blahblah</span> </td> </tr> </tbody> </table> </div> And here's the resulting Datagrid HTML: <table cellspacing="0" border="0" id="dgSelect" style="border-collapse:collapse;"> <tr onMouseOver="this.style.backgroundColor='lightgrey'"> <td> <span id="dgSelect_ctl03_lbldas">blahblah</span> </td> </tr> </table> See.. the main difference is the tag. It never gets set in the gridview.. and I don't know why.. I've traced through it.. and the code gets run.. :S

  • PHP hooks information and help needed

    - by sea_1987
    Background I am realtively new to hooks, and I have been asked to use a hook to populate a view with some data, currently the view gathers it data from a function that is in the model, and becuase the whole object is being passed to the view I can access the function. The function looks like this, public function numCVInSector($k) { $this->load->model('SYSector'); $sectorModel = new SYSector(); $cvs = $sectorModel->fetchRelatedCV($k); $cvs = $cvs[0]['count']; if($cvs == "0") { return false; } else { return $cvs; } } it call's a query in the model that looks like this, public function fetchRelatedCV($k) { $sql = "SELECT sector_id, COUNT(sector_id) as count FROM sy_user_sectors WHERE sector_id = $k"; //print_r($sql); $query = $this->db->query($sql); return $query->result_array(); } $k is the id of element that is in the view. The Problem I have been asked to use a hook that is in the parent of the model the hook is called post populate, now I have very little idea of what a hook is or how to use one to implement my function. Could some one give me some advice, the code where the hook is original made looks like this, public function populate($where = array()) { $results = array( "success" => false, "is_error" => false, "error_code" => "", "error_message" => "" ); if(empty($where) && empty($this->aliases['id'])){ $results['is_error'] = true; $results['error_message'] = 'No criteria.'; return $results; } // [hook] $this->prePopulate(); $where = count($where) > 0 ? $where : array('id' => $this->aliases['id']); $query = $this->db->get_where($this->tableName, $where, 1); if($query->num_rows() < 1){ $results['error_message'] = 'Empty results.'; return $results; } foreach($query->result_array() as $row){ foreach($this->aliases as $key => $val){ $this->aliases[$key] = $row[$key]; } } // [hook] $this->postPopulate(); // Presume success $results['success'] = true; return $results; } I have been asked to use the postPopulate hook. public function postPopulate() { $args = $this->getHookArgs('post_populate'); if(!is_array($args)){ // $this->fb->log($args, 'bad args'); return false; } // code here... // Convert dates to front end formats. foreach($this->frontEndDateFields as $fieldName => $dateFormat){ $dateRes = mlib_du_getFormattedMySQLDate($this->aliases[$fieldName], $dateFormat); if($dateRes != false){ $this->aliases[$fieldName] = $dateRes; } } return true; }

  • How to design a high-level application protocol for metadata syncing between devices and server?

    - by Jaanus
    I am looking for guidance on how to best think about designing a high-level application protocol to sync metadata between end-user devices and a server. My goal: the user can interact with the application data on any device, or on the web. The purpose of this protocol is to communicate changes made on one endpoint to other endpoints through the server, and ensure all devices maintain a consistent picture of the application data. If user makes changes on one device or on the web, the protocol will push data to the central repository, from where other devices can pull it. Some other design thoughts: I call it "metadata syncing" because the payloads will be quite small, in the form of object IDs and small metadata about those ID-s. When client endpoints retrieve new metadata over this protocol, they will fetch actual object data from an external source based on this metadata. Fetching the "real" object data is out of scope, I'm only talking about metadata syncing here. Using HTTP for transport and JSON for payload container. The question is basically about how to best design the JSON payload schema. I want this to be easy to implement and maintain on the web and across desktop and mobile devices. The best approach feels to be simple timer- or event-based HTTP request/response without any persistent channels. Also, you should not have a PhD to read it, and I want my spec to fit on 2 pages, not 200. Authentication and security are out of scope for this question: assume that the requests are secure and authenticated. The goal is eventual consistency of data on devices, it is not entirely realtime. For example, user can make changes on one device while being offline. When going online again, user would perform "sync" operation to push local changes and retrieve remote changes. Having said that, the protocol should support both of these modes of operation: Starting from scratch on a device, should be able to pull the whole metadata picture "sync as you go". When looking at the data on two devices side by side and making changes, should be easy to push those changes as short individual messages which the other device can receive near-realtime (subject to when it decides to contact server for sync). As a concrete example, you can think of Dropbox (it is not what I'm working on, but it helps to understand the model): on a range of devices, the user can manage a files and folders—move them around, create new ones, remove old ones etc. And in my context the "metadata" would be the file and folder structure, but not the actual file contents. And metadata fields would be something like file/folder name and time of modification (all devices should see the same time of modification). Another example is IMAP. I have not read the protocol, but my goals (minus actual message bodies) are the same. Feels like there are two grand approaches how this is done: transactional messages. Each change in the system is expressed as delta and endpoints communicate with those deltas. Example: DVCS changesets. REST: communicating the object graph as a whole or in part, without worrying so much about the individual atomic changes. What I would like in the answers: Is there anything important I left out above? Constraints, goals? What is some good background reading on this? (I realize this is what many computer science courses talk about at great length and detail... I am hoping to short-circuit it by looking at some crash course or nuggets.) What are some good examples of such protocols that I could model after, or even use out of box? (I mention Dropbox and IMAP above... I should probably read the IMAP RFC.)

  • java gui changing picture causes heapspace error

    - by pie154
    I have a java programme than when a button is clicked it updates the image on screen to the according image. this will work for the first 15 or so clicks then it causes a java heapspace error. I think it is because of the way I am updating the jpanel that contains the bufferedimage but not sure what the reason is. My code to get make the JPanel contain the new image is, public class extraScreenPanel { static JPanel screenPanel = new JPanel(new BorderLayout()); public static JPanel extraScreenPanel(int dispNum) { JLabel label = new JLabel("" + dispNum + ""); label.setPreferredSize(new Dimension(800, 600)); //label.setUI( new VerticalLabelUI(true) ); label.setVerticalAlignment( SwingConstants.TOP ); screenPanel = imgDisp(dispNum); label.setForeground(Color.white); label.setFont(new Font("Serif", Font.BOLD, 200)); screenPanel.add(label, BorderLayout.PAGE_END ); return screenPanel; } public static JPanel imgDisp(int picNum) { /* String url[] = new String[5000]; String part1; url[0] = "C:/PiPhotoPic/pic16.jpg"; for(Integer i=1;i<5000;i++){ if(i<10){part1 = "C:/temp/new0000000";} else if(i<100){part1 = "C:/temp/new000000";} else if(i<1000){part1 = "C:/temp/new00000";} else {part1 = "C:/temp/new00000";} String num = Integer.toString(i); url[i]= part1 + num + ".jpg"; } if(picNum<0){picNum=0;} String ref = url[picNum];*/ //this code is just to get specific ref for image location BufferedImage loadImg = loadImage(ref); JImagePanel panel = new JImagePanel(loadImg, 0, 0); panel.setPreferredSize(new Dimension(800, 600)); return panel; } public static class JImagePanel extends JPanel{ private BufferedImage image; int x, y; public JImagePanel(BufferedImage image, int x, int y) { super(); this.image = image; this.x = x; this.y = y; } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); g.drawImage(image, x, y, null); } } public static BufferedImage loadImage(String ref) { BufferedImage bimg = null; try { bimg = javax.imageio.ImageIO.read(new File(ref)); } catch (Exception e) { e.printStackTrace(); } BufferedImage bimg2 = resize(bimg,800,600); return bimg2; } public static BufferedImage resize(BufferedImage img, int newW, int newH) { int w = img.getWidth(); int h = img.getHeight(); BufferedImage dimg = dimg = new BufferedImage(newW, newH, img.getType()); Graphics2D g = dimg.createGraphics(); g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR); g.drawImage(img, 0, 0, newW, newH, 0, 0, w, h, null); g.dispose(); return dimg; } } And the code that updates my gui is, it works by removing the panel from its containg panel and then readding it to it. picPanel = imgDisp.imgDisp(num); repaintPicPanel(); public static void repaintPicPanel() { picPanel.removeAll(); menuPanel.remove(picPanel);; menuPanel.add(picPanel, BorderLayout.LINE_START); }

  • When Clearing an ObservableCollection, There are No Items in e.OldItems

    - by cplotts
    I have something here that is really catching me off guard. I have an ObservableCollection of T that is filled with items. I also have an event handler attached to the CollectionChanged event. When you Clear the collection it causes an CollectionChanged event with e.Action set to NotifyCollectionChangedAction.Reset. Ok, that's normal. But what is weird is that neither e.OldItems or e.NewItems has anything in it. I would expect e.OldItems to be filled with all items that were removed from the collection. Has anyone else seen this? And if so, how have they gotten around it? Some background: I am using the CollectionChanged event to attach and detach from another event and thus if I don't get any items in e.OldItems ... I won't be able to detach from that event. CLARIFICATION: I do know that the documentation doesn't outright state that it has to behave this way. But for every other action, it is notifying me of what it has done. So, my assumption is that it would tell me ... in the case of Clear/Reset as well. Below is the sample code if you wish to reproduce it yourself. First off the xaml: <Window x:Class="ObservableCollection.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" > <StackPanel> <Button x:Name="addButton" Content="Add" Width="100" Height="25" Margin="10" Click="addButton_Click"/> <Button x:Name="moveButton" Content="Move" Width="100" Height="25" Margin="10" Click="moveButton_Click"/> <Button x:Name="removeButton" Content="Remove" Width="100" Height="25" Margin="10" Click="removeButton_Click"/> <Button x:Name="replaceButton" Content="Replace" Width="100" Height="25" Margin="10" Click="replaceButton_Click"/> <Button x:Name="resetButton" Content="Reset" Width="100" Height="25" Margin="10" Click="resetButton_Click"/> </StackPanel> </Window> Next, the code behind: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using System.Collections.ObjectModel; namespace ObservableCollection { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public Window1() { InitializeComponent(); _integerObservableCollection.CollectionChanged += new System.Collections.Specialized.NotifyCollectionChangedEventHandler(_integerObservableCollection_CollectionChanged); } private void _integerObservableCollection_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e) { switch (e.Action) { case System.Collections.Specialized.NotifyCollectionChangedAction.Add: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Move: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Remove: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Replace: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Reset: break; default: break; } } private void addButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.Add(25); } private void moveButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.Move(0, 19); } private void removeButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.RemoveAt(0); } private void replaceButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection[0] = 50; } private void resetButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.Clear(); } private ObservableCollection<int> _integerObservableCollection = new ObservableCollection<int> { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 }; } }

  • Lighting and OpenGL ES

    - by FX
    Hi all, I'm working on getting a simple lighting right on my OpenGL ES iPhone scene. I'm displaying a simple object centered on the origin, and using an arcball to rotate it by touching the screen. All this works nicely, except I try to add one fixed light (fixed w.r.t. eye position) and it is badly screwed: the whole object (an icosahedron in this example) is lit uniformly, i.e. it all appears in the same color. I have simplified my code as much as possible so it's standalone and still reproduces what I experience: glClearColor (0.25, 0.25, 0.25, 1.); glClear (GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glEnable (GL_DEPTH_TEST); glEnable(GL_LIGHTING); glMatrixMode (GL_PROJECTION); glLoadIdentity (); glOrthof(-1, 1, -(float)backingWidth/backingHeight, (float)backingWidth/backingHeight, -10, 10); glMatrixMode (GL_MODELVIEW); glLoadIdentity (); GLfloat ambientLight[] = { 0.2f, 0.2f, 0.2f, 1.0f }; GLfloat diffuseLight[] = { 0.8f, 0.8f, 0.8, 1.0f }; GLfloat specularLight[] = { 0.5f, 0.5f, 0.5f, 1.0f }; GLfloat position[] = { -1.5f, 1.0f, -400.0f, 0.0f }; glEnable(GL_LIGHT0); glLightfv(GL_LIGHT0, GL_AMBIENT, ambientLight); glLightfv(GL_LIGHT0, GL_DIFFUSE, diffuseLight); glLightfv(GL_LIGHT0, GL_SPECULAR, specularLight); glLightfv(GL_LIGHT0, GL_POSITION, position); glShadeModel(GL_SMOOTH); glEnable(GL_NORMALIZE); float currRot[4]; [arcball getCurrentRotation:currRot]; glRotatef (currRot[0], currRot[1], currRot[2], currRot[3]); float f[4]; f[0] = 0.5; f[1] = 0; f[2] = 0; f[3] = 1; glMaterialfv (GL_FRONT_AND_BACK, GL_AMBIENT, f); glMaterialfv (GL_FRONT_AND_BACK, GL_DIFFUSE, f); f[0] = 0.2; f[1] = 0.2; f[2] = 0.2; f[3] = 1; glMaterialfv (GL_FRONT_AND_BACK, GL_SPECULAR, f); glEnableClientState (GL_VERTEX_ARRAY); drawSphere(0, 0, 0, 1); where the drawSphere function actually draws an icosahedron: static void drawSphere (float x, float y, float z, float rad) { glPushMatrix (); glTranslatef (x, y, z); glScalef (rad, rad, rad); // Icosahedron const float vertices[] = { 0., 0., -1., 0., 0., 1., -0.894427, 0., -0.447214, 0.894427, 0., 0.447214, 0.723607, -0.525731, -0.447214, 0.723607, 0.525731, -0.447214, -0.723607, -0.525731, 0.447214, -0.723607, 0.525731, 0.447214, -0.276393, -0.850651, -0.447214, -0.276393, 0.850651, -0.447214, 0.276393, -0.850651, 0.447214, 0.276393, 0.850651, 0.447214 }; const GLubyte indices[] = { 1, 11, 7, 1, 7, 6, 1, 6, 10, 1, 10, 3, 1, 3, 11, 4, 8, 0, 5, 4, 0, 9, 5, 0, 2, 9, 0, 8, 2, 0, 11, 9, 7, 7, 2, 6, 6, 8, 10, 10, 4, 3, 3, 5, 11, 4, 10, 8, 5, 3, 4, 9, 11, 5, 2, 7, 9, 8, 6, 2 }; glVertexPointer (3, GL_FLOAT, 0, vertices); glDrawElements (GL_TRIANGLES, sizeof(indices)/sizeof(indices[0]), GL_UNSIGNED_BYTE, indices); glPopMatrix (); } A movie of what I see as the result is here. Thanks to anyone who can shed some light into this (no kidding!). I'm sure it will look embarassingly trivial to someone, but I swear I have looked at many lighting tutorials before this and am stuck.

  • log-back and thirdparty writing to stdout. How to stop them getting interleaved.

    - by David Roussel
    First some background. I have a batch-type java process run from a DOS batch script. All the java logging goes to stdout, and the batch script redirects the stdout to a file. (This is good for me because I can ECHO from the script and it gets into the log file, so I can see all the java JVM command line args, which is great for debugging.) I may not I use slf4j API, and for the backend I used to use log4j, but recently switched to logback-classic. Although all my application code uses slf4j, I have a third party library that does it's own logging (not using a standard API) which also gets written to stdout. The problem is that sometimes log lines get mixed up and don't cleanly appear on separate lines. Here is an example of some messed up output: 2010-05-28 18:00:44.783 [thread-1 ] INFO CreditCorrelationElementBuilderImpl - Bump parameters exist for scenario, now attempting bumping. [indexDisplayName=STANDARD_S1_v300] 2010-05-28 18:01:43.517 [thread-1 ] INFO CreditCorrelationElementBuilderImpl - Found adjusted point in data, now applying bump.

So logback must be doing something different. The problem seems to be that although PrintStream.write(byte buf[], int off, int len) is synchronized, however I can see in ch.qos.logback.core.joran.spi.ConsoleTarget that System.out.write(int b) is the only write method called. So inbetween logback outputting each byte, the thirdparty library is managing to write a whole string to the stdout. (Not only is this cause me a problem, but it must also be a little inefficient?) Is there any other fix to this interleaving problem than patching the code to ConsoleTarget so it implments the other write methods? Any nice work arounds. Or should I just file a bug report? Here is my logback.xml: <configuration> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%-16thread] %-5level %-35.35logger{30} - %msg%n</pattern> </encoder> </appender> <root level="DEBUG"> <appender-ref ref="STDOUT" /> </root> </configuration> I'm using logback 0.9.20 with java 1.6.0_07.

  • How to overlay a div (or any element) over a table row (tr)?

    - by slolife
    I'd like to overlay a div (or any element that'll work) over a table row (tr tag) that happens to have more than one column. I have tried a few methods, which don't seem to work. I've posted my current code below. I do get an overlay, but not directly over just the row. I tried setting the overlay top to $divBottom.css('top'), but that is always 'auto'. So, am I on the right track, or is there a better way of doing it? Utilizing jQuery is fine as you can see. If I am on the right track, how do I get the div placed correctly? Is the offsetTop an offset in the containing element, the table, and I need to do some math? Any other gotchas I'll run into with that? <html> <head> <title>Overlay Tests</title> <style> #rowBottom { outline:red solid 2px } #divBottom { margin:1em; font-size:xx-large; position:relative; } #divOverlay { background-color:Silver; text-align:center; position:absolute; z-index:10000; opacity:0.5; } </style> </head> <body> <p align="center"><a id="lnkDoIt" href="#">Do it!</a></p> <table width="100%" border="0" cellpadding="10" cellspacing="3" style="position:relative"> <tr> <td><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p></td> </tr> <tr id="rowBottom"> <td><div id="divBottom"><p align="center">This is the bottom text</p></div></td> </tr> <tr> <td><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p></td> </tr> </table> <div id="divOverlay" style=""><p>This is the overlay div.</p><p id="info"></p></div> <script src="../includes/javascript/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { $('#lnkDoIt').click(function() { var $divBottom = $('#rowBottom'); var $divOverlay = $('#divOverlay'); var bottomTop = $divBottom.attr('offsetTop'); var bottomLeft = $divBottom.attr('offsetLeft'); var bottomWidth = $divBottom.css('width'); var bottomHeight = $divBottom.css('height'); $divOverlay.css('top', bottomTop); $divOverlay.css('left', bottomLeft); $divOverlay.css('width', bottomWidth); $divOverlay.css('height', bottomHeight); $('#info').text('Top: ' + bottomTop + ' Left: ' + bottomLeft); }); }); </script> </body> </html>

  • jquery selecting all last elements of an nested tree menu unordered list...not just the :last-child.

    - by Ronedog
    I'm having some trouble figuring this out. I have an unordered list menu that I want to style all the last elements with a folder icon and style all the expandable (parent) elements with a plus.gif image. I wanted to simply change the class by using .addclass() using jquery, which will contain the css to add the background-image. My jquery code below is only selecting the ":last-child", which is placing a folder icon on the last element in the list. i need to place a folder icon in front of all the "li's" that don't hav any children, and place a plus icon in front of all those that do have children. Is there a way to accomplish this? Here's my HTML: <ul id="nav"> <li>Heading 1 <ul> <li>Sub page A <ul> <li>Sub page A - 1 <ul> <li>A - 1: 0</li> <li>A - 1: 1</li> <li>A - 1: 2</li> </ul> </li> <li>Sub page A - 3</li> <li>Sub page A - 2</li> </ul> </li> <li>Sub page B</li> <li>Sub page C <ul> <li>Sub page C - 1 <ul> <li>C - 1: 0</li> <li>C - 1: 1</li> <li>C - 1: 2</li> </ul> </li> <li>Sub page C - 3</li> <li>Sub page C - 2</li> </ul> </li> </ul> </li> <li>Heading 2 <ul> <li>Sub page D</li> <li>Sub page E</li> <li>Sub page F</li> </ul> </li> <li>Heading 3 <ul> <li>Sub page G</li> <li>Sub page H</li> <li>Sub page I</li> </ul> </li> </ul> Here's the jquery code: $(function(){ //add class to last item in each list $('#nav li').find('li:last').addClass('menu_last_child'); });

  • Jquery Close/Open Multiple Toggles

    - by Pedro
    Hi, I have the toggle in my menu Working successfully for the two links that I have within it. Because the top link once toggled covers the other link, there is no problem. But since the link beneath it leaves the top link exposed, a user could click that and now have two toggled items open and pretty much stacked on top of each other. Is there a way for me to check if the other toggled item is open and if so, close it?

  • SurfaceView drawn on top of other elements after coming back from specific activity

    - by spirytus
    I have an activity with video preview displayed via SurfaceView and other views positioned over it. The problem is when user navigates to Settings activity (code below) and comes back then the surfaceview is drawn on top of everything else. This does not happen when user goes to another activity I have, neither when user navigates outside of app eg. to task manager. Now, you see in code below that I have setContentVIew() call wrapped in conditionals so it is not called every time when onStart() is executed. If its not wrapped in if statements then all works fine, but its causing loosing lots of memory (5MB+) each time onStart() is called.

  • Hover/Fadeto/Toggle Multiple Class Changing

    - by Slick Willis
    So my problem is rather simple and complex at the same time. I am trying to create links that fade in when you mouseover them and fade out when you mouseout of them. At the same time that you are going over them I would like a pic to slide from the left. This is the easy part, I have every thing working. The image fades and another image slides. I did this by using a hover, fadeto, and toggle("slide"). I would like to do this in a table format with multiple images being able to be scrolled over and sliding images out. The problem is that I am calling my sliding image to a class and when I hover over the letters both images slide out. Does anybody have a solution for this? I posted the code that I used below: <html> <head> <script type='text/javascript' src='http://accidentalwords.squarespace.com/storage/jquery/jquery-1.4.2.min.js'></script> <script type='text/javascript' src='http://accidentalwords.squarespace.com/storage/jquery/jquery-custom-181/jquery-ui-1.8.1.custom.min.js'></script> <style type="text/css"> .text-slide { display: none; margin: 0px; width: 167px; height: 50px; } </style> <script> $(document).ready(function(){ $(".letterbox-fade").fadeTo(1,0.25); $(".letterbox-fade").hover(function () { $(this).stop().fadeTo(250,1); $(".text-slide").toggle("slide", {}, 1000); }, function() { $(this).stop().fadeTo(250,0.25); $(".text-slide").toggle("slide", {}, 1000); }); }); </script> </head> <body style="background-color: #181818"> <table> <tr> <td><div class="letterbox-fade"><img src="http://accidentalwords.squarespace.com/storage/sidebar/icons/A-Letterbox-Selected.png" /></div></td> <td><div class="text-slide"><img src="http://accidentalwords.squarespace.com/storage/sidebar/icons/TEST.png" /></div></td> </tr> <tr> <td><div class="letterbox-fade"><img src="http://accidentalwords.squarespace.com/storage/sidebar/icons/B-Letterbox-Selected.png" /></div></td> <td><div class="text-slide"><img src="http://accidentalwords.squarespace.com/storage/sidebar/icons/TEST.png" /></div></td> </tr> </table> </body> </html>

  • How to play audio in Java Application

    - by user577829
    I'm making a java application and I need to play audio. I'm playing mainly small sound files of my cannon firing (its a cannon shooting game) and the projectiles exploding, though I plan on having looping background music. I have found two different methods to accomplish this, but both don't work how I want. The first method is literally a method: public void playSoundFile(File file) {//http://java.ittoolbox.com/groups/technical-functional/java-l/sound-in-an-application-90681 try { //get an AudioInputStream AudioInputStream ais = AudioSystem.getAudioInputStream(file); //get the AudioFormat for the AudioInputStream AudioFormat audioformat = ais.getFormat(); System.out.println("Format: " + audioformat.toString()); System.out.println("Encoding: " + audioformat.getEncoding()); System.out.println("SampleRate:" + audioformat.getSampleRate()); System.out.println("SampleSizeInBits: " + audioformat.getSampleSizeInBits()); System.out.println("Channels: " + audioformat.getChannels()); System.out.println("FrameSize: " + audioformat.getFrameSize()); System.out.println("FrameRate: " + audioformat.getFrameRate()); System.out.println("BigEndian: " + audioformat.isBigEndian()); //ULAW format to PCM format conversion if ((audioformat.getEncoding() == AudioFormat.Encoding.ULAW) || (audioformat.getEncoding() == AudioFormat.Encoding.ALAW)) { AudioFormat newformat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, audioformat.getSampleRate(), audioformat.getSampleSizeInBits() * 2, audioformat.getChannels(), audioformat.getFrameSize() * 2, audioformat.getFrameRate(), true); ais = AudioSystem.getAudioInputStream(newformat, ais); audioformat = newformat; } //checking for a supported output line DataLine.Info datalineinfo = new DataLine.Info(SourceDataLine.class, audioformat); if (!AudioSystem.isLineSupported(datalineinfo)) { //System.out.println("Line matching " + datalineinfo + " is not supported."); } else { //System.out.println("Line matching " + datalineinfo + " is supported."); //opening the sound output line SourceDataLine sourcedataline = (SourceDataLine) AudioSystem.getLine(datalineinfo); sourcedataline.open(audioformat); sourcedataline.start(); //Copy data from the input stream to the output data line int framesizeinbytes = audioformat.getFrameSize(); int bufferlengthinframes = sourcedataline.getBufferSize() / 8; int bufferlengthinbytes = bufferlengthinframes * framesizeinbytes; byte[] sounddata = new byte[bufferlengthinbytes]; int numberofbytesread = 0; while ((numberofbytesread = ais.read(sounddata)) != -1) { int numberofbytesremaining = numberofbytesread; sourcedataline.write(sounddata, 0, numberofbytesread); } } } catch (Exception e) { e.printStackTrace(); } } The problem with this is that my entire program stops until the sound file is finished, or at least nearly finished. The second method is this: File file = new File("Launch1.wav"); AudioClip clip; try { clip = JApplet.newAudioClip(file.toURL()); clip.play(); } catch (Exception e) { e.getMessage(); } The problem I have here is that every time the sound file ends early or doesn't play at all depending on where I place the code. Is their any way to play sound without the above mentioned problems? Am I doing something wrong? Any help is greatly appreciated.

  • Updating D3 column chart with different values and different data sizes

    - by mbeasley
    Background I am attempting to create a reusable chart object with D3.js. I have setup a chart() function that will produce a column chart. On a click event on any of the columns, the chart will update with a new random data array that will contain a random number of data points (i.e. the original chart could have 8 columns, but upon update, could have 20 columns or 4 columns). Problem Say I have 8 data points (and thus 8 columns) in my original dataset. When I update the chart with random data, the columns appropriately adjust their height to the new values - but new bars aren't added. Additionally, while the width of the columns appropriately adjust to accommodate the width of the container and the new number of data points, if that number of data points is less than the original set, then some of those columns from the original dataset will linger until the number of data points is greater than or equal than the original. My end goal is to have new data dynamically added or old data outside of the range of the new data count dynamically removed. I've created a jsfiddle of the behavior. You may have to click the columns a couple of times to see the behavior I'm describing. Additionally, I've pasted my code below. Thanks in advance! function chart(config) { // set default options var defaultOptions = { selector: '#chartZone', class: 'chart', id: null, data: [1,2,6,4, 2, 6, 7, 2], type: 'column', width: 200, height: 200, callback: null, interpolate: 'monotone' }; // fill in unspecified settings in the config with the defaults var settings = $.extend(defaultOptions, config); function my() { // generate chart with this function var w = settings.width, h = settings.height, barPadding = 3, scale = 10, max = d3.max(settings.data); var svg = d3.select(settings.selector) // create the main svg container .append("svg") .attr("width",w) .attr("height",h); var y = d3.scale.linear().range([h, 0]), yAxis = d3.svg.axis().scale(y).ticks(5).orient("left"), x = d3.scale.linear().range([w, 0]); y.domain([0, max]).nice(); x.domain([0, settings.data.length - 1]).nice(); var rect = svg.selectAll("rect") .data(settings.data) .enter() .append("rect") .attr("x", function(d,i) { return i * (w / settings.data.length); }) .attr("y", function(d) { return h - h * (d / max); }) .attr("width", w / settings.data.length - barPadding) .attr("height", function(d) { return h * (d / max); }) .attr("fill", "rgb(90,90,90)"); svg.append("svg:g") .attr("class", "y axis") .attr("transform", "translate(-4,0)") .call(yAxis); svg.on("click", function() { var newData = [], maxCap = Math.round(Math.random() * 100); for (var i = 0; i < Math.round(Math.random()*100); i++) { var newNumber = Math.random() * maxCap; newData.push(Math.round(newNumber)); } newMax = d3.max(newData); y.domain([0, newMax]).nice(); var t = svg.transition().duration(750); t.select(".y.axis").call(yAxis); rect.data(newData) .transition().duration(750) .attr("height", function(d) { return h * (d / newMax); }) .attr("x", function(d,i) { return i * (w / newData.length); }) .attr("width", w / newData.length - barPadding) .attr("y", function(d) { return h - h * (d / newMax); }); }); } my(); return my; } var myChart = chart();

  • MediaElement not showing in custom 3D class

    - by user3271180
    I'm trying to display a videostream in a Viewport3d. When I add the MediaElement via xaml, the video plays without a problem; even when I add the video as ModelVisual3D in the code-behind, the video works. When I abstract the video into a class, however, the video stops appearing. This happens with both web and local video files. I tried compiling with both x86 and 64 bit. Any way to fix this behaviour? Why is this happening? I have the following viewport: <Viewport3D> <!-- Camera --> <Viewport3D.Camera> <PerspectiveCamera Position="0,0,100" LookDirection="0,0,-1" UpDirection="0,1,0" /> </Viewport3D.Camera> <!-- Light --> <ModelVisual3D> <ModelVisual3D.Content> <AmbientLight Color="White" /> </ModelVisual3D.Content> </ModelVisual3D> <!-- this doesn't work --> <mediaElementTest:VideoControl /> <!-- but this does? --> <!--<ModelVisual3D> <ModelVisual3D.Content> <GeometryModel3D> <GeometryModel3D.Geometry> <MeshGeometry3D Positions="-100,-100,0 100,-100,0 100,100,0 -100,100,0" TextureCoordinates="0,1 1,1 1,0 0,0" TriangleIndices="0 1 2 0 2 3" /> </GeometryModel3D.Geometry> <GeometryModel3D.Material> <DiffuseMaterial> <DiffuseMaterial.Brush> <VisualBrush> <VisualBrush.Visual> <MediaElement Source="http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4" /> </VisualBrush.Visual> </VisualBrush> </DiffuseMaterial.Brush> </DiffuseMaterial> </GeometryModel3D.Material> </GeometryModel3D> </ModelVisual3D.Content> </ModelVisual3D>--> </Viewport3D> VideoControl.xaml <UIElement3D x:Class="MediaElementTest.VideoControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"/> VideoControl.xaml.cs public partial class VideoControl { public VideoControl() { InitializeComponent(); Visual3DModel = CreateModel(); } private GeometryModel3D CreateModel() { return new GeometryModel3D { Geometry = new MeshGeometry3D { Positions = new Point3DCollection { new Point3D(-100, -100, 0), new Point3D(100, -100, 0), new Point3D(100, 100, 0), new Point3D(-100, 100, 0) }, TextureCoordinates = new PointCollection { new Point(0, 1), new Point(1, 1), new Point(1, 0), new Point(0, 0) }, TriangleIndices = new Int32Collection { 0, 1, 2, 0, 2, 3 } }, Material = new DiffuseMaterial(new VisualBrush(new MediaElement { Source = new Uri("http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4", UriKind.RelativeOrAbsolute) })) }; } }
