  • How do I capture keystrokes on the web?

    - by Sean
    Using PHP, JS, or HTML (or something similar) how would I capture keystokes? Such as if the user presses ctrl+f or maybe even just f, a certain function will happen. ++++++++++++++++++++++++EDIT+++++++++++++++++++ Ok, so is this correct, because I can't get it to work. And I apologize for my n00bness is this is an easy question, new to jQuery and still learning more and more about JS. <script> var element = document.getElementById('capture'); element.onkeypress = function(e) { var ev = e || event; if(ev.keyCode == 70) { alert("hello"); } } </script> <div id="capture"> Hello, Testing 123 </div> ++++++++++++++++EDIT++++++++++++++++++ Here is everything, but I can't get it to work: <link rel="icon" href="favicon.ico" type="image/x-icon"> <style> * { margin: 0px } div { height: 250px; width: 630px; overflow: hidden; vertical-align: top; position: relative; background-color: #999; } iframe { position: absolute; left: -50px; top: -130px; } </style> <script> document.getElementsByTagName('body')[0].onkeyup = function(e) { var ev = e || event; if(ev.keyCode == 70 && ev.ctrlKey) { //control+f alert("hello"); } } </script> <div id="capture"> Hello, Testing 123<!--<iframe src="http://www.pandora.com/" scrolling="no" width="1000" height="515"frameborder="0"></iframe>--> </div>

  • Doctrine: Unable to execute either CROSS JOIN or SELECT FROM Table1, Table2?

    - by ropstah
    Using Doctrine I'm trying to execute either a 1. CROSS JOIN statement or 2. a SELECT FROM Table1, Table2 statement. Both seem to fail. The CROSS JOIN does execute, however the results are just wrong compared to executing in Navicat. The multiple table SELECT doesn't event execute because Doctrine automatically tries to LEFT JOIN the second table. The cross join statement (this runs, however it doesn't include the joined records where the refClass User_Setting doesn't have a value): $q = new Doctrine_RawSql(); $q->select('{s.*}, {us.*}') ->from('User u CROSS JOIN Setting s LEFT JOIN User_Setting us ON us.usr_auto_key = u.usr_auto_key AND us.set_auto_key = s.set_auto_key') ->addComponent('u', 'User u') ->addComponent('s', 'Setting s') ->addComponent('us', 'u.User_Setting us') ->where('s.sct_auto_key = ? AND u.usr_auto_key = ?',array(1, $this->usr_auto_key)); And the select from multiple tables (this doesn't event run. It does not spot the many-many relationship between User and Setting in the first ->from() part and throws an exception: "User_Setting" with an alias of "us" in your query does not reference the parent component it is related to.): $q = new Doctrine_RawSql(); $q->select('{s.*}, {us.*}') ->from('User u, Setting s LEFT JOIN User_Setting us ON us.usr_auto_key = u.usr_auto_key AND us.set_auto_key = s.set_auto_key') ->addComponent('u', 'User u') ->addComponent('s', 'Setting s') ->addComponent('us', 'u.User_Setting us') ->where('s.sct_auto_key = ? AND u.usr_auto_key = ?',array(1, $this->usr_auto_key));

  • Shaping EF LINQ Query Results Using Multi-Table Includes

    - by sisdog
    I have a simple LINQ EF query below using the method syntax. I'm using my Include statement to join four tables: Event and Doc are the two main tables, EventDoc is a many-to-many link table, and DocUsage is a lookup table. My challenge is that I'd like to shape my results by only selecting specific columns from each of the four tables. But, the compiler is giving a compiler is giving me the following error: 'System.Data.Objects.DataClasses.EntityCollection does not contain a definition for "Doc' and no extension method 'Doc' accepting a first argument of type 'System.Data.Objects.DataClasses.EntityCollection' could be found. I'm sure this is something easy but I'm not figuring it out. I haven't been able to find an example of someone using the multi-table include but also shaping the projection. Thx,Mark var qry= context.Event .Include("EventDoc.Doc.DocUsage") .Select(n => new { n.EventDate, n.EventDoc.Doc.Filename, //<=COMPILER ERROR HERE n.EventDoc.Doc.DocUsage.Usage }) .ToList(); EventDoc ed; Doc d = ed.Doc; //<=NO COMPILER ERROR SO I KNOW MY MODEL'S CORRECT DocUsage du = d.DocUsage;

  • Django throws 404 at generic views

    - by x0rg
    I'm trying to get the generic views for a date-based archive working in django. I defined the urls as described in a tutorial, but django returns a 404 error whenever I want to access an url with a variable (such as month or year) in it. It don't even produces a TemplateDoesNotExist-execption. Normal urls without variables work fine. Here's my urlconf: from django.conf.urls.defaults import * from zurichlive.zhl.models import Event info_dict = { 'queryset': Event.objects.all(), 'date_field': 'date', 'allow_future': 'True', } urlpatterns += patterns('django.views.generic.date_based', (r'events/(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(?P<slug>[-w]+)/$', 'object_detail', dict(info_dict, slug_field='slug',template_name='archive/detail.html')), (r'^events/(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(?P<slug>[-w]+)/$', 'object_detail', dict(info_dict, template_name='archive/list.html')), (r'^events/(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/$','archive_day',dict(info_dict,template_name='archive/list.html')), (r'^events/(?P<year>d{4})/(?P<month>[a-z]{3})/$','archive_month', dict(info_dict, template_name='archive/list.html')), (r'^events/(?P<year>)/$','archive_year', dict(info_dict, template_name='archive/list.html')), (r'^events/$','archive_index', dict(info_dict, template_name='archive/list.html')), ) When I access /events/2010/may/12/this-is-a-slug I should get to the detail.html template, but instead I get a 404. What am I doing wrong?

  • Can't get my Jscrollpane working in my Jtextarea

    - by Bobski
    I've looked around quite a lot on google and followed several examples however I can't seem to get my JScrollPane working on a textarea in a JPanel. import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.lang.*; import javax.swing.event.*; class main { public static void main(String Args[]) { frame f1 = new frame(); } } class frame extends JFrame { JButton B = new JButton("B"); JButton button = new JButton("A"); JTextArea E = new JTextArea("some lines", 10, 20); JScrollPane scrollBar = new JScrollPane(E); JPanel grid = new JPanel (); frame() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(500,800); setTitle("Mobile Phone App"); setLocationRelativeTo(null); E.setLineWrap(true); E.setEditable(false); grid.add(button); button.addActionListener(new action()); grid.add(B); B.addActionListener(new action()); //grid.add(E); grid.getContentPane().add(scrollBar); add(grid); setVisible(true); } class action implements ActionListener { public void actionPerformed(ActionEvent e) { String V = E.getText(); if(e.getSource() == button) { E.setText(V + "A is pressed"); } if(e.getSource() == B) { E.setText(V + "B is pressed"); } } } } Would be great if someone can see where I am going wrong. I added JscrollPane in which I added the text area "e" in it.

  • How can I bind multiple Jquery UI Slider with "year" Select?

    - by arthur_br
    Hi, I'm trying to render sliders instead of select components. Each page has several select components marked with class='jqselect' and all of them will have decreasing year values (some years may be missing). Eg. a select may have values [2010, 2009, 2006, 2005, 2004]. I have tried binding it both following the examples in the jQuery UI doc (but ignoring the missing years) and using selectToUISlider by filamentgroup (http://www.filamentgroup.com/lab/update_jquery_ui_slider_from_a_select_element_now_with_aria_support//). None of them work. Here is what I've done so far: Binding selects with following slider container divs: $('#content div.jqslider').slider({ animate: true, min: $(this).prev().children().last().val(), max: $(this).prev().children().first().val(), slide: function(event, ui) { var select = $(this).prev(); select.val($(this).slider('option', 'value')); console.log($(this).slider('option', 'value')); //debug } }); This renders the slider, but console logs values from 0 to 100 and selects obviously does not change with the event. Using selectToUISlider: $('#content select.jqselect').selectToUISlider(); This does not even render the slider, throwing an error 'b is undefined' in jquery-min.js (line 30, v1.4.2). If I pass the identifier of only one of the sliders, it is rendered but very buggy. Please, I'm stucked in the by two days and any help is much appreciated. Regards, Arthur

  • Determining selected state of jQuery Buttons

    - by lloydphillips
    I've got two radio buttons in a .net page which are being transformed to jQuery buttons a la http://jqueryui.com/demos/button/#radio When the page is loaded I have button 2 as checked. When clicking the buttons I'm firing the postback event. Problem is you can click on that button that is selected by default on the initial load i.e. Button 2, the postback is fired but the event handler isn't called in the .net code behind because the radio button is already classed as selected (and in normal circumstances wouldn't allow the postback to fire). To get around this I've added the e.PreventDefault() method BUT this is causing issues when Button 1 is clicked because before the click handler is called the button is set to selected. Therefore, in every case in the following code e.PreventDefault() is called: $(document).ready(function(){ $("[id*='rbPayable']").click(function(e){ if ($("[id*='rbPayable']").attr("checked")) e.preventDefault(); else setTimeout('__doPostBack(\'this.id\',\'\')', 0) }) $("[id*='rbReceivable']").click(function(e){ if ($("[id*='rbReceivable']").attr("checked")) e.preventDefault(); else setTimeout('__doPostBack(\'this.id\',\'\')', 0) }) }); What is the best way for me to load the page and effectively be able to do the following: 'If rbReceivable is checked then don't do anything otherwise do a postback.'

  • jquery tabbed interface breaks when using images

    - by Steve
    hello all, using jquery to create a tabbed interface. coding is quite typical: html: <div id="tabbed-interface"> <ul> <li><a href="#option1">Option1</a></li> <li><a href="#option2">Option2</a></li> <li><a href="#option3">Option3</a></li> </ul> </div> jquery: $(document).ready(function(){ $('#tabbed-interface li:first').addClass('active'); $('#tabbed-interface div').not(':first').hide(); $('#tabbed-interface>ul>li>a').click(function(event){ $('#tabbed-interface>ul>li').removeClass('active'); $(event.target).parent().addClass('active'); $('#tabbed-interface>div').fadeOut().filter(this.hash).fadeIn(250); return false;});}); css: ul li {background: #232323; list-style: none; border: 1px solid #616161; } ul li.active {background: none; list-style: none; border: 1px solid: #616161; border-bottom: 1px solid #121212; z-index: 1; } as you can see, all this does is add the class 'active' to the li that is clicked, and this corresponds to whether a background is shown or not. this works perfectly with text, but i am required to use non standard fonts. when i try to side step the issue using transparent .png images, it is unreliable. For instance, changing the HTML to: <div id="tabbed-interface"> <ul> <li><a href="#option1"><img src="option1.png" /></a></li>

  • populate drop-down values dynamically using Ajax

    - by abhishek
    Hi, I have 3 drop-downs. 1st drop-down contains some values when the page loads. I need to populate 2 nd drop-down based on the value selected in 1st dropdown. Similarly, I need to populate 3 nd drop-down based on the value selected in 1st and 2nd dropdown. Initially I tried like this. <h:selectOneMenu value="#{stu.country}" > <f:selectItems value="#{bean.allCountries}" /> <a4j:support event="onchange" action="#{bean.retrieveStates(stu.country)}" reRender="states_dropDown"></a4j:support> </h:selectOneMenu> //ly, for 2nd drop-down <h:selectOneMenu id="states_dropDown" value="#{stu.state}" > <f:selectItems value="#{bean.allStates}" /> <a4j:support event="onchange" action="#{bean.retrieveCities(stu.country,stu.state)}" reRender="City_dropDown"></a4j:support> </h:selectOneMenu> Some times this code works fine. But some times it doesn't invoke managed bean method. Can you please help??

  • Populate table fields on query execution

    - by Jason
    I'm trying to build an ASP site that populates a Table based on the results of a selection in a ListBox. In order to do this, I've created a GridView table inside a div element. Currently the default behavior is to show all the items in the specified table in sortable order. However, I'd like to refine this further to allow for display of matches based on the results from the ListBox selection, but am not sure how to execute this. The ListBox fires off a OnSelectionChanged event to the method defined below and the GridView element is defined as <asp:GridView ID="dataListings" runat="server" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="LinqDataSource1" OnDataBinding="ListBox1_SelectedIndexChanged"> protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e) { int itemSelected = selectTopics.SelectedIndex; string[] listing = null; switch (itemSelected)//assign listing the array of course numbers { case 0: break; case 1: listing = arts; break; case 2: listing = currentEvents; break; .... More cases here default: listing = arts; break; } using (OLLIDBDataContext odb = new OLLIDBDataContext()) { var q = from c in odb.tbl_CoursesAndWorkshops where listing.Contains(c.tbl_Course_Description.tbl_CoursesAndWorkshops.course_workshop_number) select c; dataListings.DataSource = q; dataListings.DataBind(); } } However, this method never gets fired. I can see a request being made when changing the selection, but setting a breakpoint at the method declaration does nothing at all. Based on this, setup, I have three related questions What do I need to modify to get the OnSelectionChanged event handler to fire? How can I alter the GridView area to be empty on page load? How do I send the results from the dataListings.DataBind() execution to show in the GridView?

  • Dell Vostro 3500 battery life remaining missing from Windows 8?

    - by Misha
    On Windows 7 a Vostro 3500 laptop shows the battery life remaining, while on Windows 8 this information appears to be missing. The percentage is still available, but the life remaining is missing. How is battery life remaining calculated and does this require some level of driver support? Is it a standardized interface? Does anybody know which driver is responsible for handling this feature? I want to force the old Windows 7 driver, but I don't know which driver does battery remaining.

  • Problem: Movie Clip contains just one frame

    - by Doug
    I'm a newbie at Flash, so started playing with a pretty standard code sample: one layer contains a movie clip with a flying rectangle, another layer has a button to control it. All script code is in Main.as file. The rectangle was named square1 through the Property window. Here is the problem: the constructor for Main has a line: square1.stop(); to prevent clip from playing, but it doesn't help - it plays. I know the constructor fires, because it has trace("stuff") in it. The code does check that the stage has been created. What strange is that square1.currentFrame always returns 1, and square1.totalFrames returns 1 as well. The layer has 24 frames on the timeline. I tried a tween with just 2 keyframes, then converted whole tween into frames - same result. I mean, the thing is flying before my eyes, how can it be 1 frame??? I even added a listener: square1.addEventListener(Event.ENTER_FRAME, onFrameChange); The event fires all the time, i.e. the frames change, but currentFrame is still 1. Also, tried to name individual frames and use square1.gotoAndStop("begin") and stuff like that. Nothing helps. I am really stuck with this stupid problem.

  • Global mouseMove

    - by Jacob Kofoed
    I have made the following javascript to be used in my jQuery based website. What it does, is to move a slider up/down, and scale the item above higher/smaller. Everything works fine, but since the slider is only a few pixels in height, and the move event is a bit slow (it does not trigger for every pixel) so when I move the mouse fast, the slider can't hold on and the mouse get's out of the slider item. The mouseMove event won't be triggered no more since it is bound to the slider. I guess everything could be fixed by setting the mouseMove global to the whole site, but it won't work, or at least I don't know how to make that work. Should it be bound to document, or body? here is my current code for the slider: $.fn.resize = function (itemToResize) { MinSize = 100; MaxSize = 800; pageYstart = 0; sliderMoveing = false; nuskriverHeight = 0; this.mousedown(function(e) { pageYstart=e.pageY; sliderMoveing = true nuskriverHeight = parseFloat((itemToResize).css('height')); }); this.mouseup(function() { sliderMoveing = false }); this.mousemove(function(e) { if (sliderMoveing) { (itemToResize).css('height', (nuskriverHeight + (e.pageY - pageYstart))); if (parseFloat( (itemToResize).css('height')) > MaxSize) { (itemToResize).css('height', MaxSize) }; if (parseFloat( (itemToResize).css('height')) < MinSize) { (itemToResize).css('height', MinSize) }; }; }); }; Thanks for any help, is much appreciated

  • How can I see if apache is overloaded and dropping or not accepting connections?

    - by cat pants
    Basically I just want to see if apache is handling a current level of high traffic or if I need to tune it to handle more connections. (I have found plenty of information on the actual tuning, so no help needed there) I know it has been dropping or not accepting connections earlier today, but not seeing anything in the error logs. Is the expected behavior to throw a 503 in the error log if apache cannot accept more connections? If so, what error logging level do I need in order to see these? What is the correct terminology: dropping connections or not accepting connections? MPM is prefork, OS is Linux, apache version is 2.2.15.

  • C++ MFC server app with sockets crashes and I cannot find the fault, help!

    - by usermeister
    My program has one dialog and two sockets. Both sockets are derived from CAsyncSocket, one is for listening, other is for receiving data from client. My program crashes when client tries to connect to server application and server needs to initialize receiving socket. This is my MFC dialog class. class CFileTransferServerDlg : public CDialog { ... ListeningSocket ListenSock; ReceivingSocket* RecvSock; void OnAccept(); // called when ListenSock gets connection attempt ... }; This is my derived socket class for receiving data that calls parent dialogs method when event is signaled. class ReceivingSocket : public CAsyncSocket { CFileTransferServerDlg* m_pDlg; // for accessing parent dialogs controls virtual void OnReceive(int nErrorCode); } ReceivingSocket::ReceivingSocket() { } This is dialogs function that handles incoming connection attempt when listening socket gets event notification. This is where the crash happens. void CFileTransferServerDlg::OnAccept() { RecvSock = new ReceivingSocket; /* CRASH */ } OR void CFileTransferServerDlg::OnAccept() { ReceivingSocket* tmpSock = new ReceivingSocket; tmpSock->SetParentDlg(this); CString message; if( ListenSock.Accept(*tmpSock) ) /* CRASH */ { message.LoadStringW(IDS_CLIENT_CONNECTED); m_txtStatus.SetWindowTextW(message); RecvSock = tmpSock; } } My program crashes when I try to create a socket for receiving file sent from client application. OnAccept starts when Listening socket signals incoming connection attempt, but my application then crashes. I've tried running it on another computer and connection attempt was succesful. What could be wrong? Error in debug mode: Unhandled exception at 0x009c30e1 in FileTransferServer.exe: 0xC0000005: Access violation reading location 0xccccce58.

  • FireFox: strange behavior on submiting a form

    - by ilnur777
    Can anyone help with this strange form submiting in FireFox? So this form should be submitted after pushing "go to submit" button. There is an onclick event on the button that should submit form through JavaScript. In the form there is another button "test" without any onclick event. Following the script, the form should be submitted only after pushing the "go to submit" button, but it submits even pushing at "test" button. In the Internet Explorer it works well! But this stupid FireFox browser behaves different. Here is example of HTML page: <script> function func(){ document.form1.submit(); } </script> <form name="form1" method="post" action="somewhere.php"> <button>test</button> <input type="button" value="go to submit" onclick="func();"> </form> I have several buttons with <button onclick="...">option 1</button> options. I want to fix strange submiting a form in FireFox. Help please!

  • Indirect property notification

    - by Carlo
    Hello, this question might look a little trivial, but it might not be. I'm just wondering which of the following two cases is better for indirect property notification, or perhaps there is an even better way. The scenario: I have two properties, the first one is an object called HoldingObject, the second one is a boolean called IsHoldingObject, which is false if HoldingObject == null, otherwise it's true. I'm just wondering what is the best notification mechanism for IsHoldingObject: Case (A) - Notify IsHoldingObject changed from the HoldingObject proeperty: public class NotifyingClass1 : INotifyPropertyChanged { private object _holdingObject; public object HoldingObject { get { return _holdingObject; } set { if (_holdingObject != value) { _holdingObject = value; NotifyPropertyChanged("HoldingObject"); // Notify from the property that is being checked NotifyPropertyChanged("IsHoldingObject"); } } } public bool IsHoldingObject { get { return this.HoldingObject == null; } } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; private void NotifyPropertyChanged(string propertyName) { if (this.PropertyChanged != null) this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } #endregion } Case (B) - Notify IsHoldingObject changed from the IsHoldingObject directly, by setting it to false or true from HoldingObject property: public class NotifyingClass2 : INotifyPropertyChanged { private object _holdingObject; public object HoldingObject { get { return _holdingObject; } set { if (_holdingObject != value) { _holdingObject = value; NotifyPropertyChanged("HoldingObject"); // 1) Set the property here this.IsHoldingObject = _holdingObject != null; } } } private bool _isHoldingObject; public bool IsHoldingObject { get { return _isHoldingObject; } set { if (_isHoldingObject != value) { _isHoldingObject = value; // 2) Notify directly from the property NotifyPropertyChanged("IsHoldingObject"); } } } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; private void NotifyPropertyChanged(string propertyName) { if (this.PropertyChanged != null) this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } #endregion } I personally lean to the first one because it requires less code, but I'm not sure how recommendable it is to do that. Let me know if there is another (better) way. Thanks!

  • How do I post back information from a webpage that has post-generated content?

    - by meanbunny
    Ok so I am very new to html and the web. Right now I am trying to generate list items on the fly and then have them post back to the web server so I know what the person is trying to obtain. Here is the code for generating the list items: foreach (var item in dataList) { MyDataList.InnerHtml += "<li><a runat='server' onclick='li_Click' id='" + item.Name + "-button'></a></li>"; } Further down I have my click event. protected void li_Click(object sender, EventArgs e) { //How do I determine here which item was actually clicked? } My question is how do I determine which list item was clicked? Btw, the code running behind is C#. EDIT 1 LinkButton link = new LinkButton(); link.ID = "all-button"; link.Text = "All"; link.Click += new EventHandler(link_Click); MyDataList.Controls.Add(link); Then below I have my link_Click event that never seems to hit a breakpoint. void link_Click(object sender, EventArgs e) { if (sender != null) { if (sender.GetType() == typeof(LinkButton)) { LinkButton button = (LinkButton)sender; if (button.ID == "all-button") { } } } } I know this has to be possible I just cant figure out what I am missing. Edit 2 Ok ok I think I know what the problem is. I was trying to add a second list inside of another list. This was causing the whole thing to have problems. It is working now.

Once the csv is selected I load the data into several comboboxes. 1 Thing is not working, I have a combobox containing all the citys and now I need to list all the areas for that country based on selection from the combobox. Here is the event: private void cboProvinciesItemStateChanged(java.awt.event.ItemEvent evt) { //System.out.println(Arrays.asList(gemeentesPerProvincie(gemeentes))); invullenListProvincie(gemeentes); } Here is the method: private void invullenListProvincie(ArrayList<Gemeentes> gemeentes) { Gemeentes gf = (Gemeentes) cboProvincies.getSelectedItem(); DefaultListModel model = new DefaultListModel(); JList list = new JList(model); for (Gemeentes gemeente : gemeentesPerProvincie(gemeentes)) { model.addElement(gemeente); } lstGemeentes.setModel(model); } and this is the method to filter all the areas that equal the selection from the combobox: private ArrayList<Gemeentes> gemeentesPerProvincie(ArrayList<Gemeentes> gemeentes) { String GemPerProv = (String) cboProvincies.getSelectedItem(); ArrayList<Gemeentes> selectie = new ArrayList<Gemeentes>(); for (Gemeentes gemeente : gemeentes) { if (gemeente.getsProvincie().equals(GemPerProv)) { selectie.add(gemeente); } } return selectie; } I am convinced the error is the way I am trying to add items to the jList gemeentesPerProvincie(), I have tried so many things already. I really hope someone can see what i am clearly missing...

  • Magento: How do I get observers to work in an external script?

    - by Laizer
    As far as I can tell, when a script is run outside of Magento, observers are not invoked when an event is fired. Why? How do I fix it? Below is the original issue that lead me to this question. The issue is that the observer that would apply the catalog rule is never called. The event fires, but the observer doesn't pick it up. I'm running an external script that loads up a Magento session. Within that script, I'm loading products and grabbing a bunch of properties. The one issue is that getFinalPrice() does not apply the catalog rules that apply to the product. I'm doing everything I know to set the session, even a bunch of stuff that I think is superfluous. Nothing seems to get these rules applied. Here's a test script: require_once "app/Mage.php"; umask(0); $app = Mage::app("default"); $app->getTranslator()->init('frontend'); //Probably not needed Mage::getSingleton('core/session', array('name'=>'frontend')); $session = Mage::getSingleton("customer/session"); $session->start(); //Probably not needed $session->loginById(122); $product = Mage::getModel('catalog/product')->load(1429); echo $product->getFinalPrice(); Any insight is appreciated.

  • Troubles moving a UIView.

    - by Joshua
    I have been trying to move a UIView by following a users touch. I have almost got it to work except for one thing, the UIView keeps flicking between two places. Here's the code I have been using: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchDown"); UITouch *touch = [touches anyObject]; firstTouch = [touch locationInView:self.view]; lastTouch = [touch locationInView:self.view]; [self.view setNeedsDisplay]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { InSightViewController *contentView = [[InSightViewController alloc] initWithNibName:@"SubView" bundle:[NSBundle mainBundle]]; [contentView loadView]; UITouch *touch = [touches anyObject]; currentTouch = [touch locationInView:self.view]; if (CGRectContainsPoint(contentView.view.bounds, firstTouch)) { NSLog(@"touch in subView/contentView"); sub.frame = CGRectMake(currentTouch.x - 50.0, currentTouch.y, 130.0, 21.0); } NSLog(@"touch moved"); lastTouch = currentTouch; [self.view setNeedsDisplay]; } And here's what's been happening: http://cl.ly/Sjx

  • nginx not returning 304 on cached content

    - by Don H
    I'm using nginx as a reverse proxy with an Apache back-end handling some PHP files. The files return the right expiry headers and proxy_cache does a good job of caching them, but I've noticed that the cached content returns a 200 on every refresh, when it might be more efficient to return a 304 on the cached files. The files in question are generated by PHP. The urls do not have .php in them as they've been prettified. Any idea why nginx might not be returning 304 on repeated visits to a cached PHP output? To clarify: It's using proxy_cache for caching dynamic PHP pages (not static html pages generated by PHP). I'm setting expires headers in the PHP file of time + 24 hours. With that in mind, I was hoping nginx would be able to then return 304s on its cached versions during that 24 hour window.
