  • Symfony + JQueryUI Tabs navigation menu question

    - by Andy Poquette
    I'm trying to use the tabs purely as a navigational menu, loading my pages in the tabs, but being able to bookmark said tabs, and have the address bar correspond with the action I'm executing. So here is my simple nav partial: <div id='tabs'> <ul> <li id='home'><a href="<?php echo url_for('post/index') ?>" title="Home">Home</a></li> <li id='test'><a href="<?php echo url_for('post/test') ?>" title="Test">Test</a></li> </ul> </div> And the simple tabs intializer: $(document).ready(function() { $('#tabs').tabs({spinner: '' }); }); My layout just displays $sf_content. I want to display the content for the action I'm executing (currently home or test) in the tab, via ajax, and have the tab be bookmarkable. I've googled this like 4000 times and I can't find an example of what I'm trying to do. If anyone has a resource they know of, I can look it up, or if you can help, I would greatly appreciate it. Thank you in advance.

  • Why does this Object wonk out & get deleted ?

    - by brainydexter
    Stepping through the debugger, the BBox object is okay at the entry of the function, but as soon as it enters the function, the vfptr object points to 0xccccc. I don't get it. What is causing this ? Why is there a virtual table reference in there when the object is not derived from other class. (Though, it resides in GameObject from which my Player class inherits and I retrieve the BBox from within player. But, why does the BBox have the reference ? Shouldn't it be player who should be maintained in that reference ?) For 1; some code for reference: A. I retrieve the bounding box from player. This returns a bounding box as expected. I then send its address to GetGridCells. const BoundingBox& l_Bbox = l_pPlayer-GetBoundingBox(); boost::unordered_set < Cell*, CellPHash & l_GridCells = GetGridCells ( &l_Bbox ); B. This is where a_pBoundingBox goes crazy and gets that garbage value. boost::unordered_set< Cell*, CellPHash CollisionMgr::GetGridCells(const BoundingBox *a_pBoundingBox) { I think the following code is also pertinent, so I'm sticking this in here anyways: const BoundingBox& Player::GetBoundingBox(void) { return BoundingBox( &GetBoundingSphere() ); } const BoundingSphere& Player::GetBoundingSphere(void) { BoundingSphere& l_BSphere = m_pGeomMesh-m_BoundingSphere; l_BSphere.m_Center = GetPosition(); return l_BSphere; } // BoundingBox Constructor BoundingBox(const BoundingSphere* a_pBoundingSphere); Can anyone please give me some idea as to why this is happening? Also, if you want me to post more code, please do let me know. Thanks!

  • Run an ActiveX through Web

    - by balexandre
    We have a webpage that works fine on the local computer as it uses a COM Object that is only available in the local computer. the program generates HTML code: <html> <head> <script type="text/javascript"> <!-- function ResizeControl(){Y = document.body.clientHeight;if (Y < 1) {Y = 1}X = document.body.clientWidth;if (X < 1) {X = 1}ActiveX.width = X;ActiveX.height = Y} --> </script> <style type="text/css">html, body { overflow:hidden; } </style> </head> <body OnResize="ResizeControl()" OnLoad="ResizeControl()" leftmargin="0" topmargin="0" rightmargin="0" bottommargin="0"> <object id="ActiveX" classid="CLSID:8EC68701-329D-4567-BCB5-9EE4BA43D358" width="14" height="14"> <PARAM NAME="tabName" VALUE="Complaints"> </object> </body> </html> and shows fine My question is, How can we port this into a web environment? As the Delphi developer has no idea and I'm not a Delphi fellow. I want to be able to use this "webpage" on a web address http://INTRANET/mysite/thispage.html Any idea, any though, any door to open is greatly appreciate :)

  • jquery ajax form plugin submit multiple times to the server only when using IE6

    - by Dino
    I all. I have the following form used to temporarily upload a photo on a j2ee server and then crop it with imageAreaSelect plugin : <form name="formAvatarName" id="formAvatar" method="post" action="../admin/admin-avatar-upload" enctype="multipart/form-data"> <label>Upload a Picture of Yourself</label> <input type="file" name="upload" id="upload" size="20" /> <input type="button" id="formAvatarSubmit" value="formAvatar" onclick="invia()"/> </form> I am using jquery form plugin to do ajax submission, this is my last :) attempt : $('#formAvatar').unbind('submit').bind('submit', function() { alert('aho'); $(this).ajaxSubmit(options); return false; }); Only when tested with IE6 I can see that the sumbission to the server is done multiple times (first time I got the uploaded file, the other times the sumbmission seems empty and I got error). With IE7, IE8, FFOX, CHROME is working fine. Any Ideas? Many thank in advance!

  • When dynamically adding nodes to DOM how to make browser repaint the background to avoid artefacts?

    - by Tim
    Given nested DIVs: <div id="outer" <div id = "inner" > <div id = "injectedcontent"> nodes are added to this DIV with </div> </div> </div> and this css: #outer {background-color: lightgrey; padding: 2em; width: 100%; height: 100%} #inner {background-color: white; width: 100%; height: 100%} and content injected in this manner: function injectContent(titleDivId, content){ var resultscontainer=document.getElementById('injectedcontent'); var titleDiv = document.getElementById(titleDivId); if (titleDiv == null) { titleDiv=document.createElement('div'); titleDiv.id=titleDivId; titleDiv.innerHTML += content; resultscontainer.appendChild(titleDiv); } else { titleDiv.innerHTML += content; } } the browsers do not redraw the outer DIV's background to accommodate the injected content. When I scroll the page (lots of text gets injected into the page -- it is a full-text search app) the lightgray background is painted right across the text, as shown in the attached image. Is there a way to cause the browser to recalculate page-depth after injecting content? Or is this problem related to this line: titleDiv.innerHTML += content; Is it better to add titleDiv's content a node at a time? I've recently seen respected people using innerHTML in this way, although postings from from several years ago discourage use of innerHTML. 1:

  • Encryption puzzle / How to create a PassStub for a Remote Assistance ticket

    - by Jon Clegg
    I am trying to create a ticket for Remote Assistance. Part of that requires creating a PassStub parameter. As of the documentation: http://msdn.microsoft.com/en-us/library/cc240115(PROT.10).aspx PassStub: The encrypted novice computer's password string. When the Remote Assistance Connection String is sent as a file over e-mail, to provide additional security, a password is used.<16 In part 16 they detail how to create as PassStub. In Windows XP and Windows Server 2003, when a password is used, it is encrypted using PROV_RSA_FULL predefined Cryptographic provider with MD5 hashing and CALG_RC4, the RC4 stream encryption algorithm. As PassStub looks like this in the file: PassStub="LK#6Lh*gCmNDpj" If you want to generate one yourself run msra.exe in Vista or run the Remote Assistance tool in WinXP. The documentation says this stub is the result of the function CryptEncrypt with the key derived from the password and encrypted with the session id (Those are also in the ticket file). The problem is that CryptEncrypt produces a binary output way larger then the 15 byte PassStub. Also the PassStub isn't encoding in any way I've seen before. Some interesting things about the PassStub encoding. After doing statistical analysis the 3rd char is always a one of: !#$&()+-=@^. Only symbols seen everywhere are: *_ . Otherwise the valid characters are 0-9 a-z A-Z. There are a total of 75 valid characters and they are always 15 bytes. Running msra.exe with the same password always generates a different PassStub, indicating that it is not a direct hash but includes the rasessionid as they say. Some other ideas I've had is that it is not the direct result of CryptEncrypt, but a result of the rasessionid in the MD5 hash. In MS-RA (http://msdn.microsoft.com/en-us/library/cc240013(PROT.10).aspx). The "PassStub Novice" is simply hex encoded, and looks to be the right length. The problem is I have no idea how to go from any hash to way the PassStub looks like.

  • Changing associativity

    - by Sorush Rabiee
    Hi... The associativity of stream insertion operator is rtl, forgetting this fact sometimes cause to runtime or logical errors. for example: 1st- int F() { static int internal_counter c=0; return ++c; } in the main function: //....here is main() cout<<”1st=”<<F()<<”,2nd=”<<F()<<”,3rd=”<<F(); and the output is: 1st=3,2nd=2,3rd=1 that is different from what we expect at first look. 2nd- suppose that we have an implementation of stack data structure like this: // //... a Stack<DataType> class …… // Stack<int> st(10); for(int i=1;i<11;i++) st.push(i); cout<<st.pop()<<endl<<st.pop()<<endl<<st.pop()<<endl<<st.pop()<<endl; expected output is something like: 10 9 8 7 but we have: 7 8 9 10 There is no internal bug of << implementation but it can be so confusing... and finally[:-)] my question: is there any way to change assocativity of an operator by overloading it?

  • Divide a path into N sections using Java or PostgreSQL/PostGIS

    - by Guido
    Imagine a GPS tracking system that is following the position of several objects. The points are stored in a database (PostgreSQL + PostGIS). Each path is composed by a different number of points. That is the reason why, in order to compare a pair of paths, I need to divide every path in a set of 100 points. Do you know any PostGIS function that already implement this algorithm? I've not been able to find it. If not, I'd like to solve it using Java. In this case I'd like to know an efficient and easy to implement algorithm to divide a path into N points. The most simple example could be to divide this path into three points: position 1 : x=1, y=2 position 2 : x=1, y=3 And the result should be: position 1 : x=1, y=2 (starting point) position 2 : x=5, y=2.5 position 3 : x=9, y=3 (end point) Edit: By 'compare a pair of paths' I mean to calculate the distance between two paths. I plan to divide each path in 100 points, and sum the euclidean distance between each one of these points as the distance between the two paths.

  • SWFUpload Authentication

    I am using SWFUpload to do file uploading in a ASP.NET MVC 1.0 website. It is working fine, but I am not able to authenticate the upload method. The HttpContext.User.Identity.Name returns an empty string. I am assuming this is because the Flash movie is making the post. I am also using the wrapper provided here: http://blog.codeville.net/2008/11/24/jquery-ajax-uploader-plugin-with-progress-bar/. The controller action below gets fired, but as mentiond above the user object is not passed. Any help is appreciated! View HTML <form enctype="multipart/form-data" method="post" action="/Media/Upload/Photo"> <input type="file" id="userPhoto_Photo" name="userPhoto_Photo" /> </form> Javascript $(function() { $("#userPhoto").makeAsyncUploader({ upload_url: '/Media/Upload', flash_url: '<%= Url.Content("~/Content/Flash/swfUpload-2.2.0.1.swf") %>', file_size_limit: '1 MB', file_types: '*.jpg; *.png; *.gif', button_action: SWFUpload.BUTTON_ACTION.SELECT_FILE, button_width: 210, button_height: 35, button_image_url: '<%= Url.Content("~/Content/Images/UploadPhoto.png") %>', button_text: '', button_cursor: SWFUpload.CURSOR.HAND, button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT }); }); Controller Action [AcceptVerbs(HttpVerbs.Post)] public ActionResult Upload() { if (Request.Files.Count == 1) { //Upload work } return RedirectToAction("Index", "Profile"); }

  • Refresh iFrame (Cache Issue)

    - by Ramiz Uddin
    We are getting a weird issue on which we are not sure what exactly cause it. Let me elaborate the issue. Suppose, we have two different html pages a.html and b.html. And a little script written in index.html: <html> <head> <script> function reloadFrame(iframe, src) { iframe.src = src; } </script> </head> <body> <form> <iframe id="myFrame"></iframe> <input type="button" value="Load a.html" onclick="reloadFrame(document.getElementById('myFrame'), 'a.html')"> <input type="button" value="Load b.html" onclick="reloadFrame(document.getElementById('myFrame'), 'b.html')"> </form> </body> </html> A server component is continuously updating both files a.html and b.html. The problem is the content of both files are successfully updating on the server side. If we open we can see the updated changes but client getting the older content which doesn't show the updated changes. Any idea?

  • PHP / C++ space calculations for parcel packing

    - by Andrew Willis
    I am working on a shopping cart project which requires a 'postage calculator' based on items that the person has in their cart. Obviously I will be storing the item's dimensions incl. weight and padding in a database and will also store the parcel (box) size and weight that the items will go in to, incl. box padding. Figuring the weight of the parcels will be easy but I was wondering how to go about figuring how to pack the box via PHP, that is, I would like the code to 'play tetris' with the items to make sure they get the best possible fit, giving accurate postage costs. Does anybody have any ideas on how best to achieve this or does anybody know of a PHP Class or function that can do this? EDIT: When I said 'best possible fit' maybe I was being optimistic! Having the script try every possible combination of package distribution within the parcel would be over the top, however I could improve the speed by writing the algoritm in C++ and running the program in PHP when the user 'checks out', the return value being an array with the parcel size and weight (which are all that are needed to calculate postage costs)

  • stopping backspace on multiple browsers using jQuery

    I am attempting to stop a backspace keydown event from being handled by browsers, I'm using the jquery library, so I need to get the original event, but on some browsers (firefox at least) I get an error when trying to set the original events keyCode = 0, it gives and error saying that only a getter exists for that property. function blockBackspace(event) { var altKey = event.originalEvent.altKey; var srcElementType = event.originalEvent.srcElement; if( (altKey) || ((event.keyCode == 8) && (srcElementType != "text" && srcElementType != "textarea" && srcElementType != "password")) || ((event.ctrlKey) && ((event.keyCode == 78) || (event.keyCode == 82)) ) || (event.keyCode == 116) ) { event.keyCode = 0; event.returnValue = false; event.originalEvent.keyCode = 0; event.originalEvent.returnValue = false; //sets process backspaceFlag to keep multiple handlers from removing text processBackspace = true; } } so I'm not exactly sure what to do next, every solution I find yields more problems.

  • Use the output of logs in the execution of a program

    - by myle
    When I try to create a specific object, the program crashes. However, I use a module (mechanize) which logs useful information just before the crash. If I had somehow this information available I could avoid it. Is there any way to use the information which is logged (when I use the function set_debug_redirects) during the normal execution of the program? Just to be a bit more specific, I try to emulate the login behavior in a webpage. The program crashes because it can't handle a specific Following HTTP-EQUIV=REFRESH to <omitted_url>. Given this url, which is available in the logs but not as part of the exception which is thrown, I could visit this page and complete successfully the login process. Any other suggestions that may solve the problem are welcomed. It follows the code so far.

  • Submit WordPress form programmatically

    - by songdogtech
    How can I let a user access a WordPress protected page with a URL that will submit the password in the form below? I want to be able to let a user get to a password protected WordPress page without needing to type the password, so when they go to the page, the password is submitted by a POST URL on page load. This not intended to be secure in any respect; I'll need to hardcode the password in the URL and the PHP. It's just for simplicity for the user, and once they're in, the cookie will let them in for 10 more days. I will select the particular user with separate PHP function that determines their IP or WordPress login status. I used Wireshark to find the POST string: post_password=mypassword&Submit=Submit but using this URL mydomain.com/wp-pass.php?post_password=mypassword&Submit=Submit gives me a blank page. This is the form: <form action="http://mydomain.com/wp-pass.php" method="post"> Password: <input name="post_password" type="password" size="20" /> <input type="submit" name="Submit" value="Submit" /></form> This is wp-pass.php: <?php require( dirname(__FILE__) . '/wp-load.php'); if ( get_magic_quotes_gpc() ) $_POST['post_password'] = stripslashes($_POST['post_password']); setcookie('wp-postpass_' . COOKIEHASH, $_POST['post_password'], time() + 864000, COOKIEPATH); wp_safe_redirect(wp_get_referer()); ?> What am I doing wrong? Or is there a better way to let a user into a password protected page automatically?

  • Why is OpenSubKey() returning null on my Win 7 64 bit system?

    - by BrMcMullin
    Has anyone seen OpenSubKey() and other Microsoft.Win32 registry functions return null on 64 bit systems when 32 bit registry keys are under Wow6432node in the registry? I'm working on a unit testing framework that makes a call to OpenSubKey() from the .net library. My dev system is a Win 7 64 bit environment with VS 2008 SP1 and the Win 7 SDK installed. The application we're unit testing is a 32 bit application, so the registry is virtualized under HKLM\Software\Wow6432node. When we call: Registry.LocalMachine.OpenSubKey( @"Software\MyCompany\MyApp\" ); Null is returned, however explicitly stating to look here works: Registry.LocalMachine.OpenSubKey( @"Software\Wow6432node\MyCompany\MyApp\" ); From what I understand this function should be agnostic to 32 bit or 64 bit environments and should know to jump to the virtual node. Even stranger is the fact that the exact same call inside a compiled and installed version of our application is running just fine on the same system and is getting the registry keys necessary to run; which are also being placed in HKLM\Software\Wow6432node. Any suggestions? Thanks in advance!

    I want to update a class library (a single DLL file) in a production web application. This web app is pre-compiled (published). I read an answer on StackOverflow (sorry, can't seem to find it anymore because the Search function does not work very well), that led me to believe that I could just paste the new DLL in the bin folder and it would be picked up without problems (this would cause the WP to recycle, which is fine with me because we do not use InProc session state). However, when I tried this, my site blows up and gives a FileLoadException saying that the assembly manifest definition does not match the assembly reference. What in the world is this?! Updating the DLL in Visual Studio and re-deploying the entire site works just fine, but it is a huge pain in the rear. What is the point of having a separate DLL if you have to re-deploy the entire site to implement any changes? Here's the question: How can I update a DLL on a production web site without breaking the app and without re-deploying all of the files?

  • Javascript keyup doesn't work as expected, it executes in instances where I have not removed my fing

    - by Binni
    I'm trying to create a simple game in javascript and I'm stuck on how to deal with keys. Small example: function keyUpEvent(event) { alert(event.keyCode); } window.addEventListener("keyup", keyUpEvent, false); I'm running Ubuntu 9.10 and testing it in Firefox 3.5 and Chromium. If I press and release a button instantly I get an alert, which is to be expected, but when I press and hold a button I get a small pause and then a series of alert windows, the expected result is that I only get an alert window when I remove my finger from a button. I reason it has something to do with the fact that when I press and hold a button in a text area for example I get one character, small pause, and then a series of characters: dddddddddddddddd. I believe it's possible to get around this or do it more right or whatever since this game for example: http://bohuco.net/testing/gamequery/pong.html seams not to be affected by this. But I notice if I try out the jquery keyup demo ( api.jquery.com/keyup/ ) I get the same problem. How can I implement basic game key event handling?

  • C: lseek() related question.

    - by Andrei Ciobanu
    I want to write some bogus text in a file ("helloworld" text in a file called helloworld), but not starting from the beginning. I was thinking to lseek() function. If I use the following code: #include <unistd.h> #include <fcntl.h> #include <sys/stat.h> #include <sys/types.h> #include <stdlib.h> #include <stdio.h> #define fname "helloworld" #define buf_size 16 int main(){ char buffer[buf_size]; int fildes, nbytes; off_t ret; fildes = open(fname, O_CREAT | O_TRUNC | O_WRONLY, S_IRUSR | S_IWUSR); if(fildes < 0){ printf("\nCannot create file + trunc file.\n"); } //modify offset if((ret = lseek(fildes, (off_t) 10, SEEK_END)) < (off_t) 0){ fprintf(stdout, "\nCannot modify offset.\n"); } printf("ret = %d\n", (int)ret); if(write(fildes, fname, buf_size) < 0){ fprintf(stdout, "\nWrite failed.\n"); } close(fildes); return (0); } , it compiles well and it runs without any apparent errors. Still if i : cat helloworld The output is not what I expected, but: helloworld Can Where is "Can" comming from, and where are my empty spaces ? Should i expect for "zeros" instead of spaces ? If i try to open helloworld with gedit, an error occurs, complaining that the file character encoding is unknown.

  • Why does adding Crossover to my Genetic Algorithm gives me worse results?

    - by MahlerFive
    I have implemented a Genetic Algorithm to solve the Traveling Salesman Problem (TSP). When I use only mutation, I find better solutions than when I add in crossover. I know that normal crossover methods do not work for TSP, so I implemented both the Ordered Crossover and the PMX Crossover methods, and both suffer from bad results. Here are the other parameters I'm using: Mutation: Single Swap Mutation or Inverted Subsequence Mutation (as described by Tiendil here) with mutation rates tested between 1% and 25%. Selection: Roulette Wheel Selection Fitness function: 1 / distance of tour Population size: Tested 100, 200, 500, I also run the GA 5 times so that I have a variety of starting populations. Stop Condition: 2500 generations With the same dataset of 26 points, I usually get results of about 500-600 distance using purely mutation with high mutation rates. When adding crossover my results are usually in the 800 distance range. The other confusing thing is that I have also implemented a very simple Hill-Climbing algorithm to solve the problem and when I run that 1000 times (faster than running the GA 5 times) I get results around 410-450 distance, and I would expect to get better results using a GA. Any ideas as to why my GA performing worse when I add crossover? And why is it performing much worse than a simple Hill-Climb algorithm which should get stuck on local maxima as it has no way of exploring once it finds a local max?

  • Toggle row visibility one at a time

    - by kuswantin
    I have a couple of tables with similar structures like this: <table> <tbody> <tr>content</tr> <tr>content</tr> <tr>content</tr> <tr>content</tr> <tr>content</tr> <tr>content</tr> <tr>content</tr> <tr>content</tr> ..etc --- The fake button is added here <div class="addrow">Add another</div> </tbody> </table> Since this is a long list, I have a need to toggle the rows one at a time. I just need to show the first row, of course, the rest should be toggled. The action is when I click a dynamic fake button, it will show row no. 2, and clicking again will show another next row. This is what I have done so far: $("table#field_fruit_values tr.draggable").not(':first').hide(); $("table#field_vegetables_values tr.draggable").not(':first').hide(); $("body.form table.content-multiple-table tbody").append('<div class="addrow">Add</div>'); $(".addrow").click(function() { var hiddenRow = $(this).prev('tr.draggable'); $(this).prev(hiddenRow + 1).show(); //if (hiddenRow + ':last').length) { // <= silly logic // $(this).hide(); //} }); The button only works for one row. I must have done something wrong :) When the final is reached, I also want the button to disappear. Sorry if this question sound silly. Any help would be very much appreciated. Thanks.
