  • Internet Explorer loop bug when preloading images

    - by user335460
    Hi Everyone I have created a JavaScript application that requires all images to be preloaded first. Everything works fine in Firefox but in Internet Explorer my loop skips the count at 19 and goes to 21. Has anyone come across this problem before and what causes it? You can copy and paste the script below for test purposes. var preLoad = function () { var docImages = ["http://www.sanatural.co.za/media/images/map/rsa_prov.gif", "http://www.sanatural.co.za/media/images/map/loading.gif", "http://www.sanatural.co.za/media/images/map/loading2.gif", "http://www.sanatural.co.za/media/images/map/ec_land.gif", "http://www.sanatural.co.za/media/images/map/ec_roll.gif", "http://www.sanatural.co.za/media/images/map/ec_state.gif", "http://www.sanatural.co.za/media/images/map/fs_land.gif", "http://www.sanatural.co.za/media/images/map/fs_roll.gif", "http://www.sanatural.co.za/media/images/map/fs_state.gif", "http://www.sanatural.co.za/media/images/map/gt_land.gif", "http://www.sanatural.co.za/media/images/map/gt_roll.gif", "http://www.sanatural.co.za/media/images/map/gt_state.gif", "http://www.sanatural.co.za/media/images/map/kzn_land.gif", "http://www.sanatural.co.za/media/images/map/kzn_roll.gif", "http://www.sanatural.co.za/media/images/map/kzn_state.gif", "http://www.sanatural.co.za/media/images/map/lp_land.gif", "http://www.sanatural.co.za/media/images/map/lp_roll.gif", "http://www.sanatural.co.za/media/images/map/lp_state.gif", "http://www.sanatural.co.za/media/images/map/mp_land.gif", "http://www.sanatural.co.za/media/images/map/mp_roll.gif", "mp_state.gif", "http://www.sanatural.co.za/media/images/map/nc_land.gif", "http://www.sanatural.co.za/media/images/map/nc_roll.gif", "http://www.sanatural.co.za/media/images/map/nc_state.gif", "http://www.sanatural.co.za/media/images/map/nw_land.gif", "http://www.sanatural.co.za/media/images/map/nw_roll.gif", "http://www.sanatural.co.za/media/images/map/nw_state.gif", "http://www.sanatural.co.za/media/images/map/wc_land.gif", "http://www.sanatural.co.za/media/images/map/wc_roll.gif", "http://www.sanatural.co.za/media/images/map/wc_state.gif"], imageFolder = [], loaded = [], loadedCounter = 0; this.loadImgs = function () { for (var i = 0; i < docImages.length; i++) { imageFolder[i] = new Image(); imageFolder[i].src = docImages[i]; loaded[i] = false; } intervalId = setInterval(loadedCheck, 10); // }; function loadedCheck() { if (loadedCounter == imageFolder.length) { // all images have been preloaded clearInterval(intervalId); alert('All images have been preloaded!'); return; } for (var i = 0; i < imageFolder.length; i++) { if (loaded[i] === false && imageFolder[i].complete) { loaded[i] = true; loadedCounter++; alert(i); // (work fine in FF but i.e goes from 19 to 21 ) } } } }; var preloadObject = new preLoad(); preloadObject.loadImgs();

  • AutoScaleMode problems with changed default font

    - by Doc Brown
    Hi, I have some problems with the Form.AutoScaleMode property together with fixed size controls, when using a non-default font. I boiled it down to a simple test application (WinForms 2.0) with only one form, some fixed size controls and the following properties: class Form1 : Form { // ... private void InitializeComponent() { // ... this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi; this.Font = new System.Drawing.Font("Tahoma", 9.25F); // ... } } Under 96dpi, Windows XP, the form looks correctly like this 96 dpi example. Under 120 dpi, Windows XP, the the Windows Forms autoscaling feature produces this 120 dpi example. As you can see, groupboxes, buttons, list or tree views are scaled correctly, multiline text boxes get too big in the vertical axis, and a fixed size label does not scale correctly in both vertical and horizontal direction. Seems to be bug in the .NET framework? Using the default font (Microsoft Sans Serif 8.25pt), this problem does not occur. Using AutoScaleMode=Font (with adequate AutoScaleDimensions, of course) either does not scale at all or scales exactly like seen above, depending on when the Font is set (before or after the change of AutoScaleMode). The problem is not specific to the "Tahoma" Font, it occurs also with Microsoft Sans Serif, 9.25pt. And yes, i already read this SO post http://stackoverflow.com/questions/2114857/high-dpi-problems but it does not really help me. Any suggestions how to come around this? EDIT: I changed my image hoster, hope this one works better. EDIT2: Some additional information about my intention: I have about 50 already working fixed size dialogs with several hundreds of properly placed, fixed size controls. They were migrated from an older C++ GUI framework to C#/Winforms, that's why they are all fixed-size. All of them look fine with 96 dpi using a 9.25pt font. Under the old framework, scaling to 120 dpi worked fine - all fixed size controls scaled equal in both dimensions. Last week, we detected this strange scaling behaviour under WinForms when switching to 120 dpi. You can imagine that most of our dialogs now look very bad under 120 dpi. We are looking for a solution that avoids a complete redesign all those dialogs.

  • Variables are "lost" somewhere, then reappear... all with no error thrown.

    - by rob - not a robber
    Hi All, I'm probably going to make myself look like a fool with my horrible scripting but here we go. I have a form that I am collecting a bunch of checkbox info from using a binary method. ON/SET=1 !ISSET=0 Anyway, all seems to be going as planned except for the query bit. When I run the script, it runs through and throws no errors, but it's not doing what I think I am telling it to. I've hard coded the values in the query and left them in the script and it DOES update the DB. I've also tried echoing all the needed variables after the script runs and exiting right after so I can audit them... and they're all there. Here's an example. ####FEATURES RECORD UPDATE ### HERE I DECIDE TO RUN THE SCRIPT BASED ON WHETHER AN IMAGE BUTTON WAS USED if (isset($_POST["button_x"])) { ### HERE I AM ASSIGNING 1 OR 0 TO A VAR BASED ON WHTER THE CHECKBOX WAS SET if (isset($_POST["pool"])) $pool=1; if (!isset($_POST["pool"])) $pool=0; if (isset($_POST["darts"])) $darts=1; if (!isset($_POST["darts"])) $darts=0; if (isset($_POST["karaoke"])) $karaoke=1; if (!isset($_POST["karaoke"])) $karaoke=0; if (isset($_POST["trivia"])) $trivia=1; if (!isset($_POST["trivia"])) $trivia=0; if (isset($_POST["wii"])) $wii=1; if (!isset($_POST["wii"])) $wii=0; if (isset($_POST["guitarhero"])) $guitarhero=1; if (!isset($_POST["guitarhero"])) $guitarhero=0; if (isset($_POST["megatouch"])) $megatouch=1; if (!isset($_POST["megatouch"])) $megatouch=0; if (isset($_POST["arcade"])) $arcade=1; if (!isset($_POST["arcade"])) $arcade=0; if (isset($_POST["jukebox"])) $jukebox=1; if (!isset($_POST["jukebox"])) $jukebox=0; if (isset($_POST["dancefloor"])) $dancefloor=1; if (!isset($_POST["dancefloor"])) $dancefloor=0; ### I'VE DONE LOADS OF PERMUTATIONS HERE... HARD SET THE 1/0 VARS AND LEFT THE $estab_id TO BE PICKED UP. SET THE $estab_id AND LEFT THE COLUMN DATA TO BE PICKED UP. ALL NO GOOD. IT _DOES_ WORK IF I HARD SET ALL VARS THOUGH mysql_query("UPDATE thedatabase SET pool_table='$pool', darts='$darts', karoke='$karaoke', trivia='$trivia', wii='$wii', megatouch='$megatouch', guitar_hero='$guitarhero', arcade_games='$arcade', dancefloor='$dancefloor' WHERE establishment_id='22'"); ###WEIRD THING HERE IS IF I ECHO THE VARS AT THIS POINT AND THEN EXIT(); they all show up as intended. header("location:theadminfilething.php"); exit(); THANKS ALL!!!

  • Does my fat-client application belong in the MVC pattern?

    - by boatingcow
    The web-based application I’m currently working on is growing arms and legs! It’s basically an administration system which helps users to keep track of bookings, user accounts, invoicing etc. It can also be accessed via a couple of different websites using a fairly crude API. The fat-client design loosely follows the MVC pattern (or perhaps MVP) with a php/MySQL backend, Front Controller, several dissimilar Page Controllers, a liberal smattering of object-oriented and procedural Models, a confusing bunch of Views and templates, some JavaScripts, CSS files and Flash objects. The programmer in me is a big fan of the principle of “Separation of Concerns” and on that note, I’m currently trying to figure out the best way to separate and combine the various concerns as the project grows and more people contribute to it. The problem we’re facing is that although JavaScript (or Flash with ActionScript) is normally written with the template, hence part of the View and decoupled from the Controller and Model, we find that it actually encompasses the entire MVC pattern... Swap an image with an onmouseover event - that’s Behaviour. Render a datagrid - we’re manipulating the View. Send the result of reordering a list via AJAX - now we’re in Control. Check a form field to see if an email address is in a valid format - we’re consulting the Model. Is it wise to let the database people write up the validation Model with jQuery? Can the php programmers write the necessary Control structures in JavaScript? Can the web designers really write a functional AJAX form for their View? Should there be a JavaScript overlord for every project? If the MVC pattern could be applied to the people instead of the code, we would end up with this: Model - the database boffins - “SELECT * FROM mind WHERE interested IS NULL” Control - pesky programmers - “class Something extends NothingAbstractClass{…}” View - traditionally the domain of the graphic/web designer - “” …and a new layer: Behaviour - interaction and feedback designer - “CSS3 is the new black…” So, we’re refactoring and I’d like to stick to best practice design, but I’m not sure how to proceed. I don’t want to reinvent the wheel, so would anyone have any hints or tips as to what pattern I should be looking at or any code samples from someone who’s already done the dirty work? As the programmer guy, how can I rewrite the app for backend and front end whilst keeping the two separate? And before you ask, yes I’ve looked at Zend, CodeIgnitor, Symfony, etc., and no, they don’t seem to cross the boundary between server logic and client logic!

  • Tiling rectangles seamlessly in WPF

    - by Joe White
    I want to seamlessly tile a bunch of different-colored Rectangles in WPF. That is, I want to put a bunch of rectangles edge-to-edge, and not have gaps between them. If everything is aligned to pixels, this works fine. But I also want to support arbitrary zoom, and ideally, I don't want to use SnapsToDevicePixels (because it would compromise quality when the image is zoomed way out). But that means my Rectangles sometimes render with gaps. For example: <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Background="Black"> <Canvas SnapsToDevicePixels="False"> <Canvas.RenderTransform> <ScaleTransform ScaleX="0.5" ScaleY="0.5"/> </Canvas.RenderTransform> <Rectangle Canvas.Left="25" Width="100" Height="100" Fill="#CFC"/> <Rectangle Canvas.Left="125" Width="100" Height="100" Fill="#CCF"/> </Canvas> </Page> If the ScaleTransform's ScaleX is 1, then the Rectangles fit together seamlessly. When it's 0.5, there's a dark gray streak between them. I understand why -- the combined semi-transparent edge pixels don't combine to be 100% opaque. But I would like a way to fix it. I could always just make the Rectangles overlap, but I won't always know in advance what patterns they'll be in (this is for a game that will eventually support a map editor). Besides, this would cause artifacts around the overlap area when things were zoomed way in (unless I did bevel-cut angles on the underlapping portion, which is an awful lot of work, and still causes problems at corners). Is there some way I can combine these Rectangles into a single combined "shape" that does render without internal gaps? I've played around with GeometryDrawing, which does exactly that, but then I don't see a way to paint each RectangleGeometry with a different-colored brush. Are there any other ways to get shapes to tile seamlessly under an arbitrary transform, without resorting to SnapsToDevicePixels?

  • Help finding longest non-repeating path through connected nodes - Python

    - by Jordan Magnuson
    I've been working on this for a couple of days now without success. Basically, I have a bunch of nodes arranged in a 2D matrix. Every node has four neighbors, except for the nodes on the sides and corners of the matrix, which have 3 and 2 neighbors, respectively. Imagine a bunch of square cards laid out side by side in a rectangular area--the project is actually simulating a sort of card/board game. Each node may or may not be connected to the nodes around it. Each node has a function (get_connections()), that returns the nodes immediately around it that it is connected to (so anywhere from 0 to 4 nodes are returned). Each node also has an "index" property, that contains it's position on the board matrix (eg '1, 4' - row 1, col 4). What I am trying to do is find the longest non-repeating path of connected nodes given a particular "start" node. I've uploaded a couple of images that should give a good idea of what I'm trying to do: In both images, the highlighted red cards are supposedly the longest path of connected cards containing the most upper-left card. However, you can see in both images that a couple of cards that should be in the path have been left out (Romania and Maldova in the first image, Greece and Turkey in the second) Here's the recursive function that I am using currently to find the longest path, given a starting node/card: def get_longest_trip(self, board, processed_connections = list(), processed_countries = list()): #Append this country to the processed countries list, #so we don't re-double over it processed_countries.append(self) possible_trips = dict() if self.get_connections(board): for i, card in enumerate(self.get_connections(board)): if card not in processed_countries: processed_connections.append((self, card)) possible_trips[i] = card.get_longest_trip(board, processed_connections, processed_countries) if possible_trips: longest_trip = [] for i, trip in possible_trips.iteritems(): trip_length = len(trip) if trip_length > len(longest_trip): longest_trip = trip longest_trip.append(self) return longest_trip else: print card_list = [] card_list.append(self) return card_list else: #If no connections from start_card, just return the start card #as the longest trip card_list = [] card_list.append(board.start_card) return card_list The problem here has to do with the processed_countries list: if you look at my first screenshot, you can see that what has happened is that when Ukraine came around, it looked at its two possible choices for longest path (Maldova-Romania, or Turkey, Bulgaria), saw that they were both equal, and chose one indiscriminantly. Now when Hungary comes around, it can't attempt to make a path through Romania (where the longest path would actually be), because Romania has been added to the processed_countries list by Ukraine. Any help on this is EXTREMELY appreciated. If you can find me a solution to this, recursive or not, I'd be happy to donate some $$ to you. I've uploaded my full source code (Python 2.6, Pygame 1.9 required) to: http://www.necessarygames.com/junk/planes_trains.zip The relevant code is in src/main.py, which is all set to run.

  • iPhone smooth move and pinch of UIImageView

    I have an image view that I'm wanting to be able to move around, and pinch to stretch it. It's all working, but it's kinda jumpy when I start to do any pinch movements.

  • Managing a difficult manager

    - by griegs
    I have a situation here at work. We are redeveloping our basic architecture across the entire company. Currently we have the following hierarchy; SQL Database <= Stored Procs not allowed. nHibernate Classes to convert nHibernate into our own objects Web Service <= for all external and [internal] calls. Class to take objects from Web Service and back into our own objects and then… Normal nTier application architecture such as Data Transformation Layer, Business layer etc. Within the database, when we are writing a hierarchy of objects to the database, say for example; Order Person Details Address Product Other We need to serialise the object and save it, in its entirety, to an image field in a table. No attempt has been made to store the objects in their own tables so that we can do useful stuff like report on it. This is an architecture that was implemented [way] before I started and as you can probably appreciate, is a complete nightmare not to mention slow as a wet weekend. We’re not even allowed to have stored procs within SQL server because in my boss’s last job they had a hundred or so and he had a problem identifying them all so therefore all stored procs are the devil. Now the same person that developed the above architecture has developed the new one. It came as no surprise that he’s essentially used the same framework only now it’s using DotNet 3.5 with interfaces and generics. We still have to go through web services, still need to serialise (everything), still not allowed to use stored procs etc. In fact, we’re only barely able to bang two rocks together here. He says to us that the framework is open for discussion but when you discuss it, unless you approve of his design, you are told flatly “No”. He simply won’t listen to any other suggestions. Even when you show him demo applications of his proposed architecture v’s yours and he can see the speed difference, he still won’t take that on board. So I guess my question is, and I know others have experienced the same things out there, how do I get through to someone like this? How do you convince someone to ditch Web Services for internal calls and applications? How do you demonstrate, and make it stick, that stored procs are a better way to go than ad-hoc sql statements? This is killing me. I don’t want to repeat the mistakes of the past and I certainly don’t want to write code that I know is going to be slow and cumbersome. Help!

  • CSS: series of floated elements without wrapping but rather scrolling horizontally

    - by tybro0103
    I'm working on a album viewer. At the top I want a horizontal container of all the image thumbnails. Right now all the thumbnails are wrapped in a div with float:left. I'm trying to figure out how to keep these thumbnails from wrapping to the next line when there are too many, but rather stay all in one horizontal row and use the scrollbar. Here's my code: (I don't want to use tables) <style type="text/css"> div { overflow:hidden; } #frame { width:600px; padding:8px; border:1px solid black; } #thumbnails_container { height:75px; border:1px solid black; padding:4px; overflow-x:scroll; } .thumbnail { border:1px solid black; margin-right:4px; width:100px; height:75px; float:left; } .thumbnail img { width:100px; height:75px; } #current_image_container img { width:600px; } </style> <div id="frame"> <div id="thumbnails_container"> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/glry-pixie-bob-kittens.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/PB-KitJan08-1.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/PB-KitJan08-3.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/PB-Jan08.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/gallery3.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/gallery4.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/Gallery-Pics/kitten3.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/Gallery-Pics/kitten1.jpg" alt="foo" /></div> </div> <div id="current_image_container"> <img src="http://www.whitetailrun.com/Pixiebobs/PBkittenpics/shani-kits/Cats0031a.jpg" alt="foo" /> </div> </div>

    - by Hough
    Hi all, Firstly, sorry for a somewhat long question but I think that many people are in the same situation as me and hopefully they can also gain some benefit from this. I'll be starting my PhD very soon which involves the fields of computer vision, pattern recognition and machine learning. Currently, I'm using opencv (2.1) C++ interface and I especially like its powerful Mat class and the overloaded operations available for matrix and image operations and seamless transformations. I've also tried (and implemented many small vision projects) using opencv python interface (new bindings; opencv 2.1) and I really enjoy python's ability to integrate opencv, numpy, scipy and matplotlib. But recently, I went back to opencv C++ interface because I felt that the official python new bindings were not stable enough and no overloaded operations are available for matrices and images, not to mention the lack of machine learning modules and slow speeds in certain operations. I've also used Matlab extensively in the past and although I've used mex files and other means to speed up the program, I just felt that Matlab's performance was inadequate for real-time vision tasks, be it for fast prototyping or not. When the project becomes larger and larger, many tasks have to be re-written in C and compiled into Mex files increasingly and Matlab becomes nothing more than a glue language. Here comes the sub-questions: For carrying out research in these fields (machine learning, vision, pattern recognition), what is your main or ideal programming language for rapid prototyping of ideas and testing algorithms contained in papers? For computer vision research work, can you list down the pros and cons of using the following languages? C++ (with opencv + gsl + svmlib + other libraries) vs Matlab (with all its toolboxes) vs python (with the imcomplete opencv bindings + numpy + scipy + matplotlib). Are there computer vision PhD/postgrad students here who are using only C++ (with all its availabe libraries including opencv) without even needing to resort to Matlab or python? In other words, given the current existing computer vision or machine learning libraries, is C++ alone sufficient for fast prototyping of ideas? If you're currently using Java or C# for your research, can you list down the reasons why they should be used and how they compare to other languages in terms of available libraries? What is the de facto vision/machine learning programming language and its associated libraries used in your research group? Thanks in advance. Edit: As suggested, I've opened the question to both academic and non-academic computer vision/machine learning/pattern recognition researchers and groups.

  • UpdateProgress with UpdatePanel not showing up in User control when page is loading

    - by Carter
    Is this typical behavior of the UpdateProgress for an ASP.Net UpdatePanel? I have an update panel with the UpdateProgress control inside of a user control window on a page. If I then make the page in the background do some loading and click a button in the user control update panel the UpdateProgress does not show up at all. It's like the UpdatePanels refresh request is not even registered until after the actual page is done doing it's business. It's worth noting that it will show up if nothing is happening in the background. The functionality I want is what you would expect. I want to loader to show up if it has to wait for anything to get it's refresh done when after the button is clicked. I know I can get this functionality if I just use jquery ajax with a static web method, but you can't have static web methods inside of a user control. I could have it in the page but it really doesn't belong there. A full-blown wcf wouldn't really be worth it in this case either. I'm trying to compromise with an UpdatePanel but these things always seem to cause me some kind of trouble. Maybe this is just the way it works? Edit:So I'll clarify a bit what I'm doing. What's happening is I have a page and all it has on it are some tools on the side and a big map. When the page initially loads it takes some time to load the map. Now if while it's loading I open up the tool (a user control) that has the update panel in question in it and click the button on this user control that should refresh the update panel with new data and show the loading sign (in the updateprogress) then the UpdateProgress loading image does not show up. However, the code run by the button click does run after the page is done loading (as expected) and The UpdateProgress will show up if nothing on the page containing the user control is loading. I just want the loader to show up while the page is loading. I thought my problem was that perhaps the map loading is in an update panel and my UpdateProgress was only being associated with the update panel for the user control's update panel. Hence, I would get no loading icon when the map was loading. This is not the case though.

  • Google Chrome audit on caching

    - by Álvaro G. Vicario
    If I run an audit on my sites with Google Chrome, I get this message in the Leverage browser caching section: The following resources are missing a cache expiration. Resources that do not specify an expiration may not be cached by browsers: A list of all the pictures follows. I get a similar notice in Leverage proxy caching: Consider adding a "Cache-Control: public" header to the following resources: Apart from pictures, I also get a notice about HTML, CSS and JavaScript files: The following resources are explicitly non-cacheable. Consider making them cacheable if possible: Its funny because I've worked hard to cache all static contents (except for pictures, where I just left Apache's default settings). Firefox does indeed store all these items in cache. Is there anything I should improve in my HTTP headers? Here's the complete header set of some items as loaded after removing the browser caché. Pictures use default settings I didn't really check before, the rest should be cachéd for three hours. I can set headers with both .htaccess and PHP.

  • Problem retrieving HTML5 video duration

    - by drebabels
    UPDATE: Ok so although I haven't solved this problem exactly, but I did figure out a work around that handles my biggest concern... the user experience. First the video doesn't begin loading until after the viewer hits the play button, so I am assuming that the duration information wasn't available to be pulled (I don't know how to fix this particular issue... although I assume that it would involve just loading the video metadata separately from the video, but I don't even know if that is possible). So to get around the fact that there is no duration data, I decided to hide the duration info (and actually the entire control) completely until you hit play. I know... its cheating. But for now it makes me happy :) That said... if anyone knows how to load the video metadata separately from the video file... please share. I think that should completely solve this problem. I am working on building a HTML5 video player with a custom interface, but I am having some problems getting the video duration information to display. My HTML is real simple (see below) <video id="video" poster="image.jpg" controls> <source src="video_path.mp4" type="video/mp4" /> <source src="video_path.ogv" type="video/ogg" /> </video> <ul class="controls"> <li class="time"><p><span id="timer">0</span> of <span id="duration">0</span></p></li> </ul> And the javascript I am using to get and insert the duration is var duration = $('#duration').get(0); var vid_duration = Math.round(video.duration); duration.firstChild.nodeValue = vid_duration; The problem is nothing happens. I know the video file has the duration data because if I just use the default controls, it displays fine. But the real strange thing is if I put alert(duration) in my code like so alert(duration); var vid_duration = Math.round(video.duration); duration.firstChild.nodeValue = vid_duration; then is works fine (minus the annoying alert that pops up). Any ideas what is happening here or how I can fix it?

  • How to detect if Asp.Net form is valid

    - by Hasan Gürsoy
    Hi, I have a form which is in an updatePanel and I have a span with hidden loading image, which I want to show when user clicks to submit button but I first need to check if page is valid on client side. Also I'm making loading span visible with jQuery. Here is my code: <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> function showLoading() { $('#loader').show(); } </script> </head> <body> <asp:ScriptManager ID="smMain" runat="server"></asp:ScriptManager> <asp:UpdatePanel ID="upForm" runat="server"> <ContentTemplate> <asp:MultiView ID="mvContact" runat="server" ActiveViewIndex="0"> <asp:View ID="vDefault" runat="server"> <asp:TextBox ID="tEMail" runat="server" CssClass="input" /> <asp:RequiredFieldValidator ID="rfvEMail" runat="server" ControlToValidate="tEMail" ErrorMessage="* required" Display="Dynamic" /> <asp:RegularExpressionValidator ID="revEMail" runat="server" ControlToValidate="tEMail" ErrorMessage="* invalid" Display="Dynamic" ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" /> <asp:ImageButton ID="btnSubmit" runat="server" ImageUrl="~/Assets/Images/btnSubmit.png" ToolTip="Submit Form" style="margin:5px 5px 0 -5px" onclick="btnSubmit_Click" OnClientClick="showLoading();" /> <span id="loader"><img src="Assets/Images/loader.gif" title="Sending..." /></span> </asp:View> <asp:View ID="vResult" runat="server"> <div class="result"> <span id="lResult" runat="server">Your message is sent</span> </div> </asp:View> </asp:MultiView> </ContentTemplate> </asp:UpdatePanel> </body></html>

  • Uploading a picture to facebook

    - by kielie
    Hi guys, I am trying to upload a image to a gallery on a facebook fan page, here is my code thus far, $ch = curl_init(); $data = array('type' => 'client_cred', 'client_id' => 'app_id','client_secret'=>'secret_key',' redirect_uri'=>'http://apps.facebook.com/my-application/'); // your connect url here curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/oauth/access_token'); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $rs = curl_exec($ch); curl_close($ch); $ch = curl_init(); $data = explode("=",$rs); $token = $data[1]; $album_id = '1234'; $file= 'http://my.website.com/my-application/sketch.jpg'; $data = array(basename($file) => "@".realpath($file), //filename, where $row['file_location'] is a file hosted on my server "caption" => "test", "aid" => $album_id, //valid aid, as demonstrated above "access_token" => $token ); $ch2 = curl_init(); $url = "https://graph.facebook.com/".$album_id."/photos"; curl_setopt($ch2, CURLOPT_URL, $url); curl_setopt($ch2, CURLOPT_HEADER, false); curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch2, CURLOPT_RETURNTRANSFER, false); curl_setopt($ch2, CURLOPT_POST, true); curl_setopt($ch2, CURLOPT_POSTFIELDS, $data); $op = curl_exec($ch2); When I echo $token, I seem to be getting the token, but when I run the script, I get this error, {"error":{"type":"OAuthAccessTokenException","message":"An access token is required to request this resource."} , I have NO idea why it is doing this! Basically what I am doing in that code is getting the access token with curl, and then, uploading the photo to my album also via curl, but I keep getting that error! Any help would be appreciated, thank you!

  • Java Nimbus LAF with transparent text fields

    - by Software Monkey
    I have an application that uses disabled JTextFields in several places which are intended to be transparent - allowing the background to show through instead of the text field's normal background. When running the new Nimbus LAF these fields are opaque (despite setting setOpaque(false)), and my UI is broken. It's as if the LAF is ignoring the opaque property. Setting a background color explicitly is both difficult in several places, and less than optimal due to background images actually doesn't work - it still paints it's LAF default background over the top, leaving a border-like appearance (the splash screen below has the background explicitly set to match the image). Any ideas on how I can get Nimbus to not paint the background for a JTextField? Note: I need a JTextField, rather than a JLabel, because I need the thread-safe setText(), and wrapping capability. Note: My fallback position is to continue using the system LAF, but Nimbus does look substantially better. See example images below. Conclusions The surprise at this behavior is due to a misinterpretation of what setOpaque() is meant to do - from the Nimbus bug report: This is a problem the the orginal design of Swing and how it has been confusing for years. The issue is setOpaque(false) has had a side effect in exiting LAFs which is that of hiding the background which is not really what it is ment for. It is ment to say that the component my have transparent parts and swing should paint the parent component behind it. It's unfortunate that the Nimbus components also appear not to honor setBackground(null) which would otherwise be the recommended way to stop the background painting. Setting a fully transparent background seems unintuitive to me. In my opinion, setOpaque()/isOpaque() is a faulty public API choice which should have been only: public boolean isFullyOpaque(); I say this, because isOpaque()==true is a contract with Swing that the component subclass will take responsibility for painting it's entire background - which means the parent can skip painting that region if it wants (which is an important performance enhancement). Something external cannot directly change this contract (legitimately), whose fulfillment may be coded into the component. So the opacity of the component should not have been settable using setOpaque(). Instead something like setBackground(null) should cause many components to "no long have a background" and therefore become not fully opaque. By way of example, in an ideal world most components should have an isOpaque() that looks like this: public boolean isOpaque() { return (background!=null); }

  • Javascript childNodes does not find all children of a div when appendchild has been used

    - by yesterdayze
    Alright, I am hoping someone can help me out. I apologize up front that this one may be confusing. I have included an example to try to help ease the confusion as this is better seen then heard. I have created a webpage that contains a group or set of groups. Each group has a subgroup. In a nutshell what is happening is this page will allow me to combine multiple groups containing subgroups into a new group. The page will give the chance to rename the old subgroups before they are combined into new groups in order to avoid confusion. When a group is renamed it will check to make sure there is not already a group with that name. If there is it will copy itself out of it's own group and into that group and then delete the original. If the group does not already exist it will create that group, copy itself in and then delete the original. Subgroups can also be renamed at which point they will move into the group with the same name if it exists, or create a new one if it doesn't. The page has a main div. The main div contains 'new sub group' divs. Inside each of those is another div containing the 'old sub group' divs. I use a loop through the child nodes of the 'new sub group' div when renaming a group in order to find each child node. These are then copied into a new div within the main div. The crux of the problem is this. If I loop through a DIV and copy all of the DIVs in it into a new or existing DIV all is well. When I then try to take that DIV and copy all of it's DIVs into another or new DIV it always skips one of the moved DIVs. For simplicity I have copied the entire working code below. To recreate the issue click the spot where the image should appear next to the name ewrewrwe and rename it to something else. All is well. Now click that new group the same way and name it something else. You will see it skip one each time. I have linked the page here: http://vtbikenight.com/test.html The link is clean, it is my personal website I use for a local motorycle group I am part of. Thanks for the help everyone!!! Please let me know if I can clarify on anything. I know the code is not the best right now, it is just demo code and my intent is to get the concept working then streamline it all.

  • markitup wysiwyg with a standard HTML form

    - by Chris
    Hi, I'm trying to use the markitup editor on my site and I'm having a problem trying to figure out what I need to do to submit the text area to my server side script. I'm guessing there is something simple that needs to be done but my lack of JS/JQuery knowledge is making it really hard to find a answer The editor works fine, I just want to use my own form and submit button with it, however when I try to submit the form I don't get any of the textarea data in my script. Any idea what I need to do? This is the min that works (before submit) In the Head of my HTML <script type="text/javascript" > <!-- $(document).ready(function() { $("#markItUp").markItUp(mySettings); }); --> </script> And the body: <form id="postpreview" name="newpost" action="/someurl" method="POST" /> <input type="hidden" name="key1" value="val1" /> <input type="hidden" name="key2" value="val2" /> <textarea name="text" id="markItUp"></textarea> <input id="SubmitPost" type="image" value="Continue" name="Doit" class="preview" src="/img/somimage" /> </form> As I said, everything prior to the submit works but once I submit I don't get anything for the form data element "text". I tried doing this in the head: <script type="text/javascript" > <!-- $(document).ready(function() { $("#markItUp").markItUp(mySettings); $("#SubmitPost").click(function(){ data = markItUp.textarea.value; $.post("scripturl",{ key1: "value1", key2: "value2", text: data }); }); }); --> </script> I've also tried: <script type="text/javascript" > <!-- $(document).ready(function() { $("#markItUp").markItUp(mySettings); $("#postpreview").submit(function(){ var data = $("#markItUp").html(); $.post("live",{ func: "posting", text: data }); return false; }); }); --> </script> And I have no luck - the last attempt above just disabled the form (so clicking on the submit or preview buttons did nothing). Any ideas? I guessing its really simple to use my own form but I have no clue how to do it. TIA!

  • Mac OS - Built SVN from source, now Apache2 not loading sites

    - by Geuis
    This relates to another question I asked earlier today. I built SVN 1.6.2 from source. In the process, it has completely screwed up my dev environment. After I built SVN, Apache wasn't loading. It was giving me this error: Syntax error on line 117 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec /apache2/mod_dav_svn.so into server: dlopen(/usr/libexec/apache2/mod_dav_svn.so, 10): no suitable image found. Did find:\n\t/usr/libexec/apache2/mod_dav_svn.so: mach-o, but wrong architecture It appears that SVN over-wrote the old mod_dav_svn.so and I am not able to get it to build as FAT, and I can't recover whatever was originally there. I resolved this(temporarily?) by commenting out the line that was loading the mod_dav_svn.so and got Apache to start at this point. However, even though Apache is running I am now getting this error when trying to access my dev sites: Directory index forbidden by Options directive: /usr/share/tomcat6/webapps/ROOT/ I have Apache2 sitting in front of Tomcat6. I access my local dev site using the internal name "http://localthesite". I have had virtual directories set up that have worked until this SVN debacle. Tomcat is installed at /usr/local/apache-tomcat, and webapps is /usr/local/apache-tomcat/webapps. Our production servers deploy tomcat to /usr/share/tomcat6, so I have symlinks setup on my system to replicate this as well. These point back to the actual installation path. This has all been working fine as well. None of our configurations for Apache2, Tomcat, or .htaccess have changed. Over the weekend, I performed a "Repair Disk Permissions" on the system. This was before I discovered the mod_dav_svn.so problem. I have been reading up on this all morning and the most common answer is that there is an Options -Indexes set. We have this in a config file, but it was there before and when I removed it during testing, I still got the same errors from Apache. At this point, I'm assuming I either totally borked the native Apache2 installation on this Mac, or that there is a permissions error somewhere that I'm missing. The permissions error could be from the SVN installation, or from my repair process. Does anyone have any idea what could be the problem? I'm totally blocked right now and have no idea where to check next.

  • Spring, Jersey and Viewable JSP Integration

    - by Brian D.
    I'm trying to integrate Spring 3.0.5 with Jersey 1.4. I seem to have everything working, but whenever I try and return a Viewable that points to a JSP, I get a 404 error. When I wasn't using spring I could use this filter: <filter> <filter-name>Jersey Filter</filter-name> <filter-class>com.sun.jersey.spi.container.servlet.ServletContainer</filter-class> <init-param> <param-name>com.sun.jersey.config.feature.Redirect</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>cheetah.frontend.controllers</param-value> </init-param> <init-param> <param-name>com.sun.jersey.config.feature.FilterForwardOn404</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>com.sun.jersey.config.property.WebPageContentRegex</param-name> <param-value>/(images|css|jsp)/.*</param-value> </init-param> </filter> And I could return a Viewable to any JSP's, image, css that were stored in the appropriate folder. However, now that I have to use the SpringServlet to get spring integration, I'm at a loss for how to access resources, since I can't use the filter above. I've tried using this servlet mapping with no luck: <servlet> <servlet-name>jerseyspring</servlet-name> <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class> <load-on-startup>1</load-on-startup> <init-param> <param-name>com.sun.jersey.config.property.WebPageContentRegex</param-name> <param-value>/(images|css|jsp)/.*</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>jerseyspring</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> Does anyone know the proper configurations to achieve this? Thanks for any help.

  • WPF - How do I get an object that is bound to a ListBoxItem back

    - by JonBlumfeld
    Hi there here is what I would like to do. I get a List of objects from a database and bind this list to a ListBox Control. The ListBoxItems consist of a textbox and a button. Here is what I came up with. Up to this point it works as intended. The object has a number of Properties like ID, Name. If I click on the button in the ListBoxItem the Item should be erased from the ListBox and also from the database... <ListBox x:Name="taglistBox"> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="HorizontalAlignment" Value="Stretch"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListBoxItem"> <ContentPresenter HorizontalAlignment="Stretch"/> </ControlTemplate> </Setter.Value> </Setter> <Setter Property="Tag" Value="{Binding TagSelf}"></Setter> </Style> </ListBox.ItemContainerStyle> <ListBox.ItemTemplate> <DataTemplate> <Grid HorizontalAlignment="Stretch"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Button Grid.Column="0" Name="btTag" VerticalAlignment="Center" Click="btTag_Click" HorizontalAlignment="Left"> <Image Width="16" Height="16" Source="/WpfApplication1;component/Resources/104.png"/> </Button> <TextBlock Name="tbtagBoxTagItem" Margin="5" Grid.Column="1" Text="{Binding Name}" VerticalAlignment="Center" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> The Textblock.Text is bound to object.Name and the ListBoxItem.Tag to object.TagSelf (which is just a copy of the object itself). Now my questions If I click the button in the listboxItem how do I get the listboxitem and the object bound to it back. In order to delete the object from the database I have to retrieve it somehow. I tried something like ListBoxItem lbi1 = (ListBoxItem)(taglistBox.ItemContainerGenerator.ContainerFromItem(taglistBox.Items.CurrentItem)); ObjectInQuestion t = (ObjectInQuestion) lbi1.Tag; Is there a way to automatically update the contents of the ListBox if the Itemssource changes? Right now I'm achieving that by taglistBox.ItemsSource = null; taglistBox.ItemsSource = ObjectInQuestion; I'd appreciate any help you can give :D Thanks in advance

  • create text inside a rectangle using inkscape

    - by mr calendar
    I've put some text inside a rectangle using inkscape so the tree is like <svg:rect><svg:text><svg:tspan>text.... The problem is, I can't see the text. I've tried fiddling with the opacity of the rect to no avail. There should be a way of doing this from the UI? Edit example as requested <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!-- Created with Inkscape (http://www.inkscape.org/) --> <svg xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:cc="http://creativecommons.org/ns#" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd" xmlns:inkscape="http://www.inkscape.org/namespaces/inkscape" width="184.25197" height="262.20471" id="svg2" sodipodi:version="0.32" inkscape:version="0.46" version="1.0" sodipodi:docname="ex1.svg" inkscape:output_extension="org.inkscape.output.svg.inkscape"> <defs id="defs4"> <inkscape:perspective sodipodi:type="inkscape:persp3d" inkscape:vp_x="0 : 526.18109 : 1" inkscape:vp_y="0 : 1000 : 0" inkscape:vp_z="744.09448 : 526.18109 : 1" inkscape:persp3d-origin="372.04724 : 350.78739 : 1" id="perspective10" /> </defs> <sodipodi:namedview id="base" pagecolor="#ffffff" bordercolor="#666666" borderopacity="1.0" gridtolerance="10000" guidetolerance="10" objecttolerance="10" inkscape:pageopacity="0.0" inkscape:pageshadow="2" inkscape:zoom="0.64" inkscape:cx="195.9221" inkscape:cy="335.3072" inkscape:document-units="px" inkscape:current-layer="layer1" showgrid="false" inkscape:window-width="640" inkscape:window-height="675" inkscape:window-x="44" inkscape:window-y="44" /> <metadata id="metadata7"> <rdf:RDF> <cc:Work rdf:about=""> <dc:format>image/svg+xml</dc:format> <dc:type rdf:resource="http://purl.org/dc/dcmitype/StillImage" /> </cc:Work> </rdf:RDF> </metadata> <g inkscape:label="Layer 1" inkscape:groupmode="layer" id="layer1"> <rect style="opacity:0.25480766;fill:#ff0000;fill-opacity:1;stroke:#000000;stroke-width:12.94795799;stroke-miterlimit:4;stroke-dasharray:none;stroke-opacity:1" id="rect2383" width="150.87796" height="84.226181" x="18.221733" y="39.557121"> <text xml:space="preserve" style="font-size:56.0331955px;font-style:normal;font-weight:normal;fill:#000000;fill-opacity:1;stroke:none;stroke-width:1px;stroke-linecap:butt;stroke-linejoin:miter;stroke-opacity:1;font-family:Bitstream Vera Sans" x="44.815186" y="114.0088" id="text2385" transform="scale(1.0054479,0.9945816)"><tspan sodipodi:role="line" id="tspan2387" x="44.815186" y="114.0088">text</tspan></text> </rect> </g> </svg> I'd expect to be able to see this in inkscape. The workaround is to put text on a layer above the box (the intent is that the box obscures the layers below it) and not try and get clever with nested tags. Shame it doesn't work though.

  • Multiple Mod_ReWrites on one site - Possible? (Wordpress blog in root directory, CodeIgniter project

    - by Sootah
    Currently I am creating a project with CodeIgniter that is contained within a subdirectory of my domain. For this example we'll call it domain.com/test. I also have Wordpress installed on this domain, and all of its files are in the root. For instance, if you navigate to my domain.com then it pulls up the Wordpress blog. I currently have the Wordpress mod_rewrite activated so that it uses friendly-URLs. For those of you that aren't familiar with CodeIgniter, all requests are routed through index.php in the project's root folder. So, in this case, it'd be domain.com/text/index.php. A request to the application would be sent like domain.com/test/index.php/somecontroller/method. What I'd like to do, is for any incoming request that is directed towards the /test/ folder, or some subdirectory therein I'd like it to appropriately rewrite the URL so the index.php isn't included. (As per the example above, it'd end up being domain.com/test/somecontroller/method) For any OTHER request, meaning anything that's not within the /test/ directory, I would like it to route the request to Wordpress. I would imagine it's a simple RewriteCond to make it check to see if the request is for the /test/ directory or a subdirectory therein, but I've no idea how to do it. Perhaps you can't have more than one set of Rewrite Rules per site. I will include the recommended mod_rewrite rules for each application. Wordpress: (Currently used) <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> CodeIgniter: (Pulled from their Wiki) <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / #Removes access to the system folder by users. #Additionally this will allow you to create a System.php controller, #previously this would not have been possible. #'system' can be replaced if you have renamed your system folder. RewriteCond %{REQUEST_URI} ^system.* RewriteRule ^(.*)$ /index.php?/$1 [L] #When your application folder isn't in the system folder #This snippet prevents user access to the application folder #Submitted by: Fabdrol #Rename 'application' to your applications folder name. RewriteCond %{REQUEST_URI} ^application.* RewriteRule ^(.*)$ /index.php?/$1 [L] #Checks to see if the user is attempting to access a valid file, #such as an image or css document, if this isn't true it sends the #request to index.php RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/$1 [L] </IfModule> <IfModule !mod_rewrite.c> # If we don't have mod_rewrite installed, all 404's # can be sent to index.php, and everything works as normal. # Submitted by: ElliotHaughin ErrorDocument 404 /index.php </IfModule> Any and all help is much appreciated!! Thanks, -Sootah

  • WPF DataTemplates with VS2010 designer support + reusable - would you do it that way?

    - by Christian
    Ok, I am currently tidying up all my old stuff. I ran into the issue of "code only DataTemplates" - which are really a pain in the ass. You can't see anything, they are really hard to design, and I want to improve my project. So I had the idea to use the following solution. The main benefits are: You have designer support for your data template You can easily include example sample data The file naming is consistent and easy to remember The preview does not require an additional XAML wrapper (even with code only controls) I will try to explain and illustrate my solution using a few pictures. I am interested in feedback, especially if you can imagine a better way to do it. And, of course, if you see any maintenance or performance issues. Ok, lets start with a simple PreviewObject. I want to have some data in it, so I create a subclass which will automatically fill in some dummy data. Then I add a list to the control, and name this list. Afterwards I add a DataTemplate, this is the sole reason for the whole control (to be able to see and edit the DataTemplate in place): Now I use this control to get my DataTemplate, to use it in other places. To make this easier, I added some code in the code behind, see here: Now I want a control to show me a list of PreviewItems, so I created a "code-only" control which creates an instance of my service (or gets one using DI in real world) and fills its list box with it: To view the result of this work, I added this control inside the same named XAML, this is basically only to be able to see the final result: What I do not like in this solution: The need to create the last control in "code only". So I tried something different while writing this post. The following two screenshots illustrate the approach. I am creating an instance of the service inside the DataContext, and I am using bindings to supply the Itemssourc and the ItemTemplate. The reason for the strange "static property" is refactoring support. If I hardcode the path in the designer (e.g. using "Path = PreviewHistory") and I refactor the names (which happens quite often, early design phase) - I screw up my controls without realizing it. Does anyone has a better idea for this? I am using Resharper, btw. Thanks for any input, and sorry for the image overkill. Just easier to explain that way.. Chris
