• CSS animated menu

  - by Andrea

  I am trying to obtain something similar to the "share this on..." menu here but I don't quite understand how they are doing this, even after a look at their CSS. I refer to the fact that the images show up on hover. My first attempt would be something like <div id="share_on"> <ul> <li><a href="#"><img src="shareon-digg.png" /></a></li> <li><a href="#"><img src="shareon-reddit.png" /></a></li> ... <li><a href="#"><img src="shareon-stumbleupon.png" /></a></li> </ul> </div> and the CSS: #share_on {overflow: hidden} #share_on ul {margin-bottom: -16px} #share_on li {display: inline} #share_on li:hover {margin-top: -16px} Of course this does not work, which is why I am asking here. In the inactive state, only half of the icon shows up, which is the expected behaviour. But on hover, nothing changes. I also have tried some variations, like #share_on li:hover {margin-bottom: 16px} or #share_on li:hover {padding-bottom: 16px} but none of these works. Any ideas?

• Take screenshot with Selenium: WaitForPageToLoad does not wait long enough

  - by OregonGhost

  I'm trying to get screenshots from a web page with multiple browsers. Just experimenting with Selenium RC, I wrote code like this: var sel = new DefaultSelenium(server, 4444, target, url); sel.Start(); sel.Open(url); sel.WaitForPageToLoad("30000"); var imageString = sel.CaptureScreenshotToString(); This basically works, but in most cases the screenshot is of a blank browser window, because the page is not yet ready for display. It kind of works if I add a sleep just after the WaitForPageToLoad, but that slows down the fast browsers and/or may be to short for the slower browsers (or under load). A typical solution for this seems to be to wait for the presence of a certain element. However, this is meant as a simple generic solution to get a screenshot of a local web page with as many browsers as possible (to test the layout) and I don't want to have to enter certain element names or whatever. It's a simple tool where you just enter the Selenium Server URL and the URL you want to test, and get the screenshots back. Any advice?

• javascript function won't stop looping - It's on a netsuite website

  - by Lauren

  I need to change the shipping carrier drop-down and shipping method radio button once via a javascript function, not forever. However, when I use this function, which executes when on the Review and Submit page when the order is < $5, it goes into an endless loop: function setFreeSampShipping(){ var options = document.forms['checkout'].shippingcarrierselect.getElementsByTagName('option'); for (i=0;i<options.length;i++){ if (options[i].value == 'nonups'){ document.forms['checkout'].shippingcarrierselect.value='nonups'; document.forms['checkout'].shippingcarrierselect.onchange(); document.location.href='/app/site/backend/setshipmeth.nl?c=659197&n=1&sc=4&sShipMeth=2035'; } } } It gets called from within this part of the function setSampPolicyElems() which you can see I've commented out to stop the loop: if (carTotl < 5 && hasSampp == 1) { /* if (document.forms['checkout'].shippingcarrierselect.value =='ups'){ setFreeSampShipping(); } */ document.getElementById('sampAdd').style.display="none"; document.getElementById("custbody_ava_webshiptype").value = "7";//no charge free freight if (document.getElementById("applycoupon")) { document.location.href='/app/site/backend/setpromocode.nl?c=659197&n=1&sc=4&kReferralCode=SAMPLE' } document.write("<div id='msg'><strong>Sample & Shipping:</strong></span> No Charge. (Your sample order is < $5.)</div>"); } To see the issue, go to the order review and submit page here: https://checkout.netsuite.com/s.nl?c=659197&sc=4&n=1 (or go to http://www.avaline.com, hit "checkout", and login) You can log in with these credentials: Email:[email protected] Pass:test03

• Debugging SIGABRT within NSManagedObjectContext -save:

  - by westsider

  From inside NSManagedObjectContext -save: I am getting this message: Assertion failed: (_Unwind_SjLj_Resume() can't return), function _Unwind_SjLj_Resume, file /SourceCache/libunwind/libunwind-24.1/src/Unwind-sjlj.c, line 326. Program received signal: “SIGABRT”. warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found). This happens when I delete an Experiment object with to-many with Run which has to-many with Sample which has to-one with Data. Experiment also has to-many with Page which has to-many with Display which has to-many to Run. I mention this to point out the cyclical nature of the graph. Here is a simplified graph of model: I had been using Delete Rules but have now switched to "No Action" delete rules in combination with -prepareForDeletion methods for all of these classes. This change made no difference. In both cases, the error message is the same. Interestingly, when I relaunch the app, all the objects that were marked for deletion have been deleted. Also, if an Experiment has no Run objects, then deletion works without incidence. For that matter, deleting a single Run from an Experiment also works. I am hoping that someone has seen something like this and can offer advice on what would cause this. Or, if someone has advice on how to get libXcodeDebuggerSupport.dylib for iOS 4.2.1, that might also be helpful. Update: I followed advice found here and was able to get Xcode to find libXcodeDebuggerSupport.dylib for iOS 4.2.1. But this did not help at all in diagnosing problem - which persists.

• Where is my Drupal View pager?

  - by anotherthink

  Hi, I have a Drupal 6 site where I've created a view that shows a list of nodes. Nothing complicated -- except that when I choose "use pager" -- "yes" (and choose the "full pager" option), the pager doesn't show up on the page. The first page of nodes shows up, but there's no way to get to other pages. Through googling, I saw that some people had an issue with the "Pager Element" item, so I changed that from 0 to 1 -- no luck. This shouldn't be very complicated, but I've been at it for a while! Help!? ETA: I've tracked it down to the following lines in /modules/views/theme/theme.inc: $pager_theme = views_theme_functions($pager_type, $view, $view->display_handler->display); $vars['pager'] = theme($pager_theme, $exposed_input, $view->pager['items_per_page'], $view->pager['element']); The first line returns an array; the second line returns nothing. I suspect now that this is a theming problem with the custom theme I'm using that may not have fully been correctly updated for Drupal 6 -- like, maybe I'm missing a pager template somehow? -- however, I'm quite new to Drupal and don't really understand how to further track down and fix the issue. Any advice would be much appreciated! ETA yet again: The pager also doesn't show up when using Garland, so it's not a theme issue after all. ALSO: I have a copy of this site set up on a development server as well, and that copy has working pagination! I've checked what I thought might be different -- files in the theme, what modules are enabled -- and it seems like pretty much everything is the same. The one thing that I know is different, however, is that the production server has a lower version of MySQL (lower than recommended for Drupal 6 -- we're waiting on the hosting company being able to change this later). Would it make sense that the old version of MySQL is unable to do pagination correctly in Drupal 6? If so, does anyone know a workaround I can do until we are able to update MySQL?

• Access custom error messages for InArray validator when using Zend_Form_Element_Select

  - by Ben Waine

  Hello, I'm using Zend Framework 1.62 (becuase we are deploying the finished product to a Red Hat instance, which doesn't have a hgih enough PHP version to support ZF1.62). When creating a Form using Zend Form, I add a select element, add some multi options. I use the Zend Form as an in-object validation layer, passing an objects values through it and using the isValid method to determine if all the values fall within normal parameters. Zend_Form_Element_Select works exactly as expected, showing invalid if any other value is input other than one of the multi select options I added. The problem comes when I want to display the form at some point, I cant edit the error message created by the pre registered 'InArray' validator added automatically by ZF. I know I can disable this behaviour, but it works great apart from the error messages. I've tryed the following: $this->getElement('country')->getValidator('InArray')->setMessage('The country is not in the approved lists of countries'); // Doesn't work at all. $this->getElement('country')->setErrorMessage('The country is not in the approved lists of countries'); // Causes a conflict elswhere in the application and doesnt allow granular control of error messages. Anyone have any ideas? Ben

• How do I make a jQuery POST function open the new page?

  - by ciclistadan

  I know that a submit button in HTML can submit a form which opens the target page, but how do I cause a jQuery ajax call POST information to a new page and display the new page. I am submitting information that is gathered by clicking elements (which toggle a new class) and then all items with this new class are added to an array and POSTed to a new page. I can get it to POST the data but it seems to be working functioning in an ajax non-refreshing manner, not submitting the page and redirecting to the new page. how might I go about doing this? here's the script section: //onload function $(function() { //toggles items to mark them for purchase //add event handler for selecting items $(".line").click(function() { //get the lines item number var item = $(this).toggleClass("select").attr("name"); }); $('#process').click(function() { var items = []; //place selected numbers in a string $('.line.select').each(function(index){ items.push($(this).attr('name')); }); $.ajax({ type: 'POST', url: 'additem.php', data: 'items='+items, success: function(){ $('#menu').hide(function(){ $('#success').fadeIn(); }); } }); }); return false; }); any pointers would be great!! thanks

• Silverlight client never calls WCF Service

  - by Doug Nelson

  Hi all, This one has me completed stumped. I have developed a silverlight application that calls back to WCF services ( it's a silverlight - basicHttpBinding) The site works perfectly fine from my development machine, but when it is deployed to the developement server. The application is delivered with the XAP just fine, but it never attempts to talk to the service. I have a service call in the bootstrapper so it should be calling this when the client starts up. The services are healthy. They can be browsed to and show the standard WCF service display. We have been through the bindings many times and everything seems to be ok. I have added an extensive amount of error handling for displaying any errors, but on this dev server, no service calls and no errors are being raised. Fiddler shows the page being loaded up, but my client never issues a call to the service. The service is in the same folder as the default.aspx which hosts the Silverlight client. This is a Silverlight 3.0 app. Anybody ever seen anything similar?

• How to capture page with google map?

  - by Max

  I have a UIComponent with Google map in the continer. I need to capture this container for making a preview. My integration looks like the following: <mx:UIComponent id="mapContainer" width="410" height="300" /> googleMap = new Map(); mapContainer.addChild(googleMap); But if I do("this" - is my UIComponent) var bmd:BitmapData = new BitmapData(this.width, this.height, true, 0x00ffffff); bmd.draw(this); I see the following: An ActionScript error has occurred: SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: http://localhost/ cannot access http://mt1.google.com/vt/lyrs=m@121&hl=en&src=api&x=1&y=1&z=1&s=Gali. No policy files granted access. at flash.display::BitmapData/draw() I now, that I can to add it host to allowed on the custom client. But I need to have working system on any computer ) I've tried to hide it: templateGoogleMapRenderer.mapContainer.setVisible(false); templateGoogleMapRenderer.mapContainer.includeInLayout = false; But it was unsuccessfully. May be I can override some method in my UIComponent, that flex use during BitmapData/draw() ? Capture with hidden map is success result for me )

• JQuery DatePicker - pop calendar dialog on 'OnSelect' of another datepicker

  - by sajanyamaha

  I have two JQuery datepickers to select 'StartDate' and 'EndDate'.My requirement is to automatically popup the end date calendar after startDate has been selected. I have tried all the steps in COMMENTED HERE. The code here succesfully triggers the focus of 'EndDate' calendar,but it displays for a second and hides off. $(document).ready(function() { //Runs when tab is loaded var dateFormat = "dd/mm/yy"; var today=new Date(); today.setMonth(today.getMonth()-1); $("#ctl00_ContentPlaceHolder1_datepicker1").datepicker({ minDate: 0, dateFormat:dateFormat, //maxDate: '+12M +31D', onSelect: function(dateText, inst){ var the_date = new Date($.datepicker.parseDate(dateFormat,dateText)); //var end=(the_date.getDate()+1) + '/' + (the_date.getMonth()+1) + '/' + the_date.getFullYear(); $("#ctl00_ContentPlaceHolder1_datepicker2").datepicker('option', 'minDate', the_date); // TRIED ALL THESE //document.getElementById('ui-datepicker-div').style.display = 'block'; //document.getElementById('ui-datepicker-div').style.left = '635.5px'; //$("#ctl00_ContentPlaceHolder1_datepicker2").datepicker("show"); //$("#ctl00_ContentPlaceHolder1_datepicker2").datepicker(); //$("#ctl00_ContentPlaceHolder1_datepicker2").focus(); //$('#foo').slideUp(300).delay(800).fadeIn(400); //$("#ctl00_ContentPlaceHolder1_datepicker2").trigger("focus"); $('#ctl00_ContentPlaceHolder1_datepicker2').focus(); } }); $("#ctl00_ContentPlaceHolder1_datepicker2").datepicker({ //maxDate: '+12M +31D', dateFormat:dateFormat, onSelect: function(dateText, inst){ } }); });

• QT- QImage and multi-threading problem.

  - by umanga

  Greetings all, Please refer to image at : http://i48.tinypic.com/316qb78.jpg We are developing an application to extract cell edges from MRC images from electron microscope. MRC file format stores volumetric pixel data (http://en.wikipedia.org/wiki/Voxel) and we simply use 3D char array(char***) to load and store data (gray scale values) from a MRC file. As shown in the image,there are 3 viewers to display XY,YZ and ZX planes respectively. Scrollbars on the top of the viewers use to change the image slice along an axis. Here is the steps we do when user changes the scrollbar position. 1) get the new scrollbar value.(this is the selected slice) 2) for the relavant plane (YZ,XY or ZX), generate (char* slice;) array for the selected slice by reading 3D char array (char***) 3) Create a new QImage* (Format_RGB888) and set pixel values by reading 'slice' (using img-setPixel(x,y,c);) 4) This new QImage* is painted in the paintEvent() method. We are going to execute "edge-detection" process in a seperate thread since it is an intensive process.During this process we need to draw detected curve (set of pixels) on top of above QImage*.(as a layer).This means we need to call drawPoint() methods outside the QT thread. Is it the best wayto use QImage for this case? What is the best way to execute QT drawing methods from another thread? thanks in advance,

• Things one needs to know while writing a game engine

  - by Joe Barr

  I have been dabbling in game development as a hobby for a while now, and I cannot seam to quite get my games to sparkle at least a bit with some graphics. I have decided to write a simple test game engine that only focuses on the representation of graphics - shapes, textures and surfaces. While I have a few very simple game engines designed for my own games under my belt, I want to create a game engine that I can use to display and play with graphics. I'm going to do this in C++. Since this is my first time with a major engine, the engine in not going to focus on 3D graphics, it's going to be a mixture of isometric and 2D graphics. My previous engines have incorporated (been able to draw) or focused on simple flat (almost 2D) non impressive graphic designs and representations of: the player NPCs objects walls and surfaces textures Also, I had some basic AI and sometimes even sound. They also saved and loaded games. They didn't have a map editor or a level editor. Is this going to be a problem in the future? At this time I have to point out that some of my games didn't get finished because I was to lazy to write the few last levels. My question at this point would be: What are some things one should know if one wants write (develope) a better graphical game engine with all it's functions.

• pushViewController Not Displaying UIView/Nib with tabbar and nav bar

  - by james

  I'm relatively new to objective c but not programming and am stuck with my iphone app. I created a nav based app with both a navbar and a tab bar controller. I set the tab bar as the root controller. I'm able to switch between each tab without any issues to various UIViews and UITableViews. My issue is that in one of my UITableViews that I call from the TabBarController, didSelectRowAtIndexPath function is suppose to display a new UIView. The below code does not give any errors and runs fine but does not show the new Nib. if(newViewController == nil) { NSLog(@"yes nil"); BookViewController *aNewViewController = [[BookViewController alloc] initWithNibName:@"BookOptionView" bundle:nil]; self.newViewController = aNewViewController; [aNewViewController release]; } BookAppDelegate *delegate = (BookAppDelegate *)[[UIApplication sharedApplication] delegate]; [delegate.appNavBar pushViewController:newViewController animated:YES]; Now when I do the below, it works fine but it gets rid of the nav and tab which I'm assuming because its a modal call instead of pushing the view controller. BookViewController *screen = [[BookViewController alloc] initWithNibName:@"BookOptionView" bundle:[NSBundle mainBundle]]; screen.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentModalViewController:screen animated:YES]; [screen release]; Any ideas why I can't get the View Controller to push correctly? In my application delegate file, I declared an AppNavBarController object (inherit from UINavigationController) called appNavBar. Any help would be appreciated!

• Implementing Struts 2 Interceptors using Struts 1

  - by Andriy Zakharchuk

  Hello all, I have a legacy application written with Struts 1. The only feature I was asked to add is to protect some actions. Currently any user can do whatever he/she wants. The idea is to allows all user see the data, but block modification operation, i.e. to modify data a user should log in. I know Struts2 has interceptors, so I could attach them to required actions and forward users to log in page when needed. But how can I do similar thing in Struts 1 application? My first idea was to create my own abstract Action class: public class AuthenticatedAction { public ActionForward execute( ActionMapping mapping, ActionForm form, HttpServletRequest theRequest, HttpServletResponse theResponse) { if (!logged) { // forward to log in form } else { doExecute(mapping, form, request, response); } } public abstract ActionForward doExecute( ActionMapping mapping, ActionForm form, HttpServletRequest theRequest, HttpServletResponse theResponse); } Then change all actions that require authentication from extends Action to extends AuthenticatedAction then add login form, login action (which performs authentications and puts this status into the session) and change JSP header tile to display authentication block, e.g., "You are (not logged in)/", Login/Logout. As I guess this should solve the problem. If this doesn't solve the problem, please explain me why. Is there any better (more elegant like interceptors are) way to do this? Thank you in advance.

• Variable-width inline underline effects in CSS

  - by sidereal

  I need to simulate the look of a typical paper form in CSS. It consists of a two-column table of fields. Each field consists of a field name (of variable width) followed by an underline that continues to the end of the column. The field might be populated, in which case there is some text centered above the line, or it may be blank. If that isn't clear, he's a rough idea in manky ASCII art: Name: _______Foo_______ Age: _____17______ Location: __Melbourne__ Handedness: _Left_ (except that the underline would continue under any text) To implement the underline without text, I assume I should use a border-bottom rather than a text-decoration: underline. Additionally, I need the bordered element to take up the full available space. Both of those argue for a block-level element. However, I can't find any way to get the block level element (either a div, an li, or a span set to display: block or inline-block) to remain on the same line as the label. As soon as I give it a width: 100%, it newlines. I've tried various combinations of floats, and I'm not inclined to do anything ridiculous with absolute positioning. Any recommendations?

• NSBundle loading a NSViewController

  - by Staros

  Hey all, I'm looking into a project that would upload custom NSBundles that include a NSViewController. In my main program I've got this code to deal with the bundle after it's been loaded... id principalClass = [loadedBundle principalClass]; id instance = [[principalClass alloc] init]; [localLabel setStringValue:[instance name]]; NSView *incomingView = [[instance viewController] view]; [localView addSubview:incomingView]; [localView display]; And the principal classes init method in the bundle looks like this... -(id) init { if(self = [super init]){ name = @"My Plugin"; viewController = [[ViewController alloc] initWithNibName:@"View" bundle:nil]; } return self; } View.nib is a nib located in the bundles project. But whenever I load the bundle I get this error... 2010-05-27 09:11:18.423 PluginLoader[45032:a0f] unable to find nib named: View in bundle path: (null) 2010-05-27 09:11:18.424 PluginLoader[45032:a0f] -[NSViewController loadView] could not load the "View" nib. I know I've got everything wired up because the line [label setStringValue:[instance name]]; sets the label text correctly. Plus, if I take all of the clases in the bundle and load them into my main applications project everything works as expect. Any thoughts on how I can correctly reference "View" in my bundle? Thanks!

• What is the best practice for ouputting data from a collection on an ASP.net Page?

  - by bshacklett

  I've ported a page from classic ASP to ASP.net. Part of what happens in this page is that a collection of custom types is generated and then displayed via Response.Write() commands. I'd like to get the business logic separated out into a code behind file (and maybe move this all into a user control), but I can't seem to figure out how I'd actually display the collection once it's been generated. I want to specify a master page here, too, so the code can't stay inline. Here's a very stripped down version of the current code: <% Dim objs as ArrayList = New ArrayList() For i = 0 To 2 Dim obj as Obj = New Obj() obj.setProp1("ASDF") obj.setProp2("FDSA") objs.Add(obj) Next i %> <table> <thead> <tr> <th scope="col">Property 1</th> <th scope="col">Property 2</th> </tr> </thead> <tbody> <% For Each obj As Obj In objs Dim objProp1 As String = obj.getProp1 Dim objProp2 As String = obj.getProp2 %> <tr> <td><% Response.Write(objProp1)%></td> <td><% Response.Write(objProp2)%></td> </tr> <% Next %> </tbody> </table> What is the ".net" way of doing this?

• Use any CSS compiler (Sass, Less) to generate the selector

  - by xckpd7

  So I've recently been playing around with CSS compilers, but I have no idea how (or if it's possible) to dynamically generate pieces of a selector. For instance, let's say I wanted to make mixins to get display: inline-block; to work cross browser. I would have to do the styles, yeah, but I would have to do the IE6/7 selector hacks to get them to work in those browsers too. Ideally I'm looking for a one off thing to add to an element and have the ability for that to work. Some kind person recently gave me this solution: http://stackoverflow.com/questions/2746754/css-compilers-and-converting-ie-hacks-to-conditional-css/2747036#2747036 and it would be nice to implement that in a minimal way that would allow me to specify it for a given element and be on my way (for instance in Less, you can create a class with styles, pass that class to another element, and that element will inherit all of those styles. It would be nice to pass an element .inline-block; and it create the styles needed to support IE6/7 without having to resort to stuff like _color: pink; Any ideas? EDIT: for instance as well, how could I do something like clearfix for LESS? (lesscss.org)? If Sass can only do it then that will work too.

• MKAnnotationView is not added for some annotations

  - by Dave

  I find that MKMapView has to be re-centered to a significant distance away from an existing map center to be able to add more annotations to the map and DISPLAY them. Is this a bug in SDK 3.2? I have looked literally EVERYWHERE and can't find a way to refresh the map view without having to zoom in or zoom out or move the map view. Why?? I don't mind if the solution involves doing a bunch of custom delegates and notifications. I just NEED this so bad. Basically, I am adding pins (annotations) to a map view when performing a search for businesses. I remove existing annotations on every search. So the annotations are added to the map on every search. If I search twice with the same map view, I see the results loading but the map view is empty. The pins will appear if i move/resize/zoom in. Anybody seen this? any help is appreciated.

• Android : Bitmap save to location

  - by Chrispix

  I am working on a function to download an image from a web server, redisplay it on the screen, and if the user wishes to keep the image, save it on the SD card in a certain folder. Is there an easy way to take a bitmap and just save it to the SD card in a folder of my choice? My issue is that I can download the image, display it on screen as a Bitmap. The only way I have been able to find to save an image to a particular folder is to use FileOutputStream, but that requires a byte array. I am not sure how to convert (if this is even the right way) from Bitmap to byte array, so I can use a Fileoutput stream to write the data. The other option I have is it use MediaStore : MediaStore.Images.Media.insertImage(getContentResolver(), bm, barcodeNumber + ".jpg Card Image", barcodeNumber + ".jpg Card Image"); Which works fine to save to SD card, but does not allow you to customize the folder. Any assistance would be very much appreciated. Thank you in advance.

• Sharepoint survey: How to identify the question fields when fetching survey information from the Lis

  - by paul

  I am wanting to access survey information via the Lists web service and display the questions contained in the survey. The result contains a large number of Field nodes some of which are the questions in the survey. The other fields contain other information such as author, last changed etc. How can I pick out the questions? I had thought that all non-questions would be hidden but this is not the case. Here is my code as it is at the moment. It returns about 16 items. The survey has 6 questions... // read question definitions string[] HandleTypes = new string[] { "Number", "DateTime", "Text", "Choice", "GridChoice", "Boolean" }; var query = from n in node.Descendants(ns+"Field") where (n.Attribute("Hidden") == null || n.Attribute("Hidden").Value.ToLower() == "true") && (n.Attribute("Type") != null && HandleTypes.Contains(n.Attribute("Type").Value)) select new Question(n.Attribute("ID").Value) { Text = n.Attribute("DisplayName").Value, QuestionType = n.Attribute("Type").Value, Element = n }; Ideas anyone?
