• Intellisense for Javascript - not correct in Visual Studio 2008/2010

  - by Finglas

  var obj = document.getElementById("header"); Given the above code snippet, I should be able to wire event handlers. For example, I can wire onMouseDown to the mouse down event, the issue is that Visual Studio does not display this in the Intellisense. I'm trying something such as: obj.onmousedown = mousestatus; Based on a book I'm reading, the code is valid (at least it works) therefore I see no reason why Intellisense is not picking it up. I've tried this on both a standalone Javascript file, as well as an MVC project to no luck. Is there anything I'm doing wrong - or is there a way to resolve this?

• Style Data in a gridview which dynamically generates the columns

  - by Coesy

  I have built a dynamic gridview using the following code grdVariants.Columns.Clear(); int i = 0; foreach (DataColumn column in options.Columns) { grdVariants.Columns.Add(new GridViewColumn { Header = column.ColumnName, DisplayMemberBinding = new Binding(string.Format("[{0}]", i++)) }); } This will dynamically generate my columns at runtime, I then bind the data using lstVariantsGrid.DataContext = options; lstVariantsGrid.Items.Refresh(); This all works great and shows the data in the correct columns etc, the only issue i have is that I can't style the rows like I would in xaml as it is all an unknown quantity until runtime. Can anyone offer some advice on how I might go about doing this? One of the biggest problems I have is that one of the columns needs to display the image rather than just the path which it currently shows, as well as fiddling with fonts and colors etc. Thanks for your time.

• C++ multiple definition error

  - by user231536

  Starting with sth's answer to this question: http://stackoverflow.com/questions/3023760/c-template-specialization I was wondering how to resolve multiple definition errors if the following code is put in a header file included multiple times by different .cc files and linked together: template <typename T> class C { static const int K; static ostream& print(ostream& os, const T& t) { return os << t;} }; // general case template <typename T> const int C<T>::K = 1; // specialization template <> const int C<int>::K = 2;

• Where do I put the links to my Javascript/jQuery files in my html file?

  - by Qlidnaque

  I recently noticed that some (not all) of my javascript and jQuery scripts wouldn't work unless I put the link for the .js files nearer towards the bottom of the page instead of the head area where I put my links for my .css files. From what I understand, javascript can go in either places and it is recommended to not be put in the header as it slows down the page loading process as well. At the same time, if I put it in the body tag of the html file, it looks somewhat messy and was wondering what the best practice is for putting .js files in a cleanly place. Should I always put it at the very bottom right before the ending body tag? How do professional web developers handle this?

• jKey (JavaScript key shortcut plugin) Issue

  - by Oscar Godson

  Me and a friend are writing a plugin for jQuery that makes it easy for devs to add key shortcuts and we're damn close but no cigar. We're having issues with the key combos. It seems like we are having issues when you call the same selector multiple times on a page. Try pressing alt+a... youll see it works one time, then gets all mangled up. Anyone know how to fix it? It'll be on github after it's corrected and I'd be happy to add "thank you to" link to whoever can fix this in the header with the copyright info :) It's nicely documented and i have all the code and stuff here. So... anyone? http://jsbin.com/azaha4

• Redirect URL from AJAX Calls

  - by Vincent

  All, I have an application written in Zend MVC Framework. So, naturally all regular requests and ajax requests go through /public/index.php. I want my application to support maintenance mode. So, in my index.php file, I have the following code: if( Zend_Registry::get('config')->maintenance == 'true' ) { header('Location:/maintenance.php'); } The issue is, when ajax requests are called they render servermaintenance.php inside the page instead of redirecting to this page. How can I make sure it gets redirected instead of getting rendered? Thanks

• ASF duration is 29 secs, WMP plays 25 secs. How come?

  - by Roey

  Hi All. I've created a custom ASF file containing compressed voice + screen streams. The total duration of the file according to the header is 29 secs. When opening it in WMP (using custom DMOs to play the streams), the file plays 25 seconds, and then the seek bar snaps to the beginning, but oddly, WMP continues to play 4 more seconds before stopping. Looking at the ASF with ASF Viewer - there are 29 seconds of packets , and both "play duration" and "send duration" are 29 seconds. Why would WMP only see 25 seconds?? Thanks

• FTP/SFTP module for .NET

  - by Angrius

  I am designing an auto downloader using .NET and C#. I was wondering if there is a decent/robust FTP/SFTP module out there that I can use, preferably free of charge. EDIT: I probably should've noted that I am looking for answer from somebody who tried several and found one that works very well. I currently use .NET wrapper for libcurl for FTP and it does not behave right. For example when I connect to FTP site with Filezilla and provide a path, it finds directory just fine. With libcurl, i get a header for 404 page saying path cannot be found. I am guessing that Filezilla gets 'home' directory correctly, and libcurl puts me to the root (i tried no path, and i had no permissions to access that directory). But anyways, I just don't know enough about FTP itself, so I would like something that just works. Thanks!

• Rails is caching when I don't want it to. Why?

  - by ryeguy

  Rails is caching the index method of one of my controllers. It's a very simple application and only has like 2 controllers and a handful of actions each. The weird thing is I don't have any caching in my application at all, at least not explicitly. The pages get uncached if I restart passenger. Does rails do some kind of automatic page caching? There are no files in the public directory The page is returning a 200 header I have no caching blocks in my views (I use haml, if that matters) I have no action, controller, or page caching defined The request is hitting rails, verified by the production log I have the following in my production.rb: config.cache_classes = true config.action_controller.consider_all_requests_local = false config.action_controller.perform_caching = true config.action_view.cache_template_loading = true

• Retain count = 0 in other function? memory-management problem?

  - by rdesign

  Hey guys, I declared a NSMutableArray in the header-file with: NSMutableArray *myMuArr; and @property (nonatomic, retain) NSMutableArray *myMuArr; In the .m file I've got a delegate from an other class: -(void)didGrabData:(NSArray*)theArray { self.myMuArr = [[[NSMutableArray alloc] initWithArray:myMuArr]retain]; } If I want to access the self.myMuArr in cellForRowAtIndexPath it's empty (I checked the retain count of the array and it's 0) What am I doing wrong? Of course it's released in the dealloc, no where else. I would be very thankfull for any help :0)

• Need to read .symtab

  - by user361190

  I am frustrated. I have a simple doubt .. I compile a simple program with gcc and if I see the section header using objdump, it does not show the section ".symtab". for the same a.out file, readelf shows the section. see the below snip - [25] .symtab SYMTAB 00000000 000ca4 000480 10 26 2c 4 [26] .strtab STRTAB 00000000 001124 00025c 00 0 0 1 Why ? In the default linker script I don't find a definition for .symtab section. If I add a definition by myself like in the linker script : .... PROVIDE(__start_sym) .symtab : { *(.symtab)} PROVIDE(__end_sym) .... the difference b/w the addresses of __start_sym and __end_sym is zero, which means no such section is added in the output file. But the readelf is able to read the section and dump the contents of this section .. How ? why ?

• Perl CGI script to not wait for a subprocess to complete

  - by Tyug

  Is it possible to continue displaying a CGI script's HTML without waiting for a child process to complete, yet the child process should stay alive when the CGI script is complete. Here's what I have, -- Display HTML page # html page set up... so header/other stuff #the -c, -h are params are just params system("perl subprocess.pm -c params -h 1 &"); #actually print the html page setup ... For some weird reason, it waits for the subprocess to finish before it outputs the html page even though I included the asynchronous system call for linux. It doesn't render the page immediately. Is it possible to print the html page without waiting for the subprocess to finish?

• WPF - How do I expose namespaces throughout a project

  - by Mark Pearl

  Sorry... I hope this isnt a really dumb question... but I couldnt find the answer anywhere. I have a WPF application, in each of my usercontrols / windows I am currently putting the following code in xaml in the header... xmlns:properties="clr-namespace:MaxCut2.Properties" This particular properties namespace I use in every window / usercontrol in my project and I would have thought that if I had put the code in my App.xaml, it would have been exposed to all the child windows/uc's - but it doesn't seem to work. Is there a way that I can expose this without having to declare it in every file in XAML?

• help in security assignment

  - by scatman

  i have to write a program that sniffs network packets (part1-the simple part). and i have to update the program (part2) so that it will be able to terminate connections. the specific requirements are: construct raw packets by specifying data link layer and network layer information including appropriate source and destination MAC and IP addresses. These packets are intended to terminate the connection. To do so, you should used SOCK_RAW as the socket type to be able to set the header information by yourself. can anybody give me some ideas on the second part? should i hijack the session,apply a dos attack on one of the users?? all i need is some tips of how to terminate the connection. i am using c programming language. and this is a course assignment for the security course.

• How to use database to generate multiple folder content page?

  - by VenomVipes

  Scenario :I am trying to build a Mobile Entertainment Portal. It will enable users to download Music & Movies to their Cell Phones... Problem Exp : Suppose I upload 100 folders of Songs, each folder is for one Album. I want a way to generate a page with all the folders name (Album Name) in it. If user click on the page, they should be taken to a page where they get list of all songs in the album. Clicking on any song name will let them download it. Can it be done anyway or will I have to manually design each of the 3 pages for each album. If I do that, its time consuming and also will be difficult to change anything like footer, header...

• JMS - How do message selectors work with multiple queue and topic consumers?

  - by Stephen Harmon

  Say you have a JMS queue, and multiple consumers are watching the queue for messages. You want one of the consumers to get all of a particular type of message, so you decide to employ message selectors. For example, you define a property to go in your JMS message header named, "targetConsumer." Your message selector, which you apply to the consumer known as, "A," is something like "WHERE targetConsumer = "CONSUMER_A." It's clear that consumer A will now just grab messages with the property set like it is in in the example. Will the other consumers have awareness of that, though? IOW, will another consumer, unconstrained by a message selector, grab the "CONSUMER_A" messages, if it looks at the queue before Consumer A? Do I need to apply message selectors like, "WHERE targetConsumer < "CONSUMER_A" to the others? I am RTFMing and gathering empirical data now, but was hoping someone might know off the top of their head.

• Can you detect a 301 redirect with Microsoft.XMLHTTP object?

  - by dmb

  I'm using VBScript and the Microsoft.XMLHTTP object to scrape some web data. I have a list of URLs to check, but unfortunately some of them 301 redirect to others on the list, so I wind up with redundant data. Is it at all possible to make the XMLHTTP object fail on 301 redirect? Or at least cache the original response header? Or otherwise just let me know what happened? (notes: I have no control over the server I'm requesting data from; when I get new data, I could check if it's redundant, but I'd like to avoid that if possible). Any ideas would be greatly appreciated.

• PHP cookie removal in FireFox 14.0.1

  <?php session_start(); $_SESSION['logged_in'] = false; setcookie("dsgpassword127", $password, time()-3600); /* expire the cookie */ setcookie("dsgemail127", $email, time()-3600); /* expire the cookie */ session_destroy(); header("location: index.php"); ?> The code above which works very well in Chrome will not remove the cookies in FireFox 14.0.1. I am wondering why this is, if anyone has experienced the same problem or if there is a solution to this conundrum I am in when it comes to expiring these cookies.... Thank you.

• How to get site context/information during the PreapplicationStartMethod

  - by Mike

  When you run the same web based application as a multi-tenant application for different clients is there a way during the PreapplicationStartMethod to gain some kind of context to the site that is being started? More specifically I'd like to get the host header information (the "bindingInformation" attribute value from the applicationHost.config); I have found ways to get this information at the time of a specific request long after the application has started. Is there a way to get the information during the application startup process? This is an MVC 3 application and IIS 7.5.

• How do I implement SAML 2.0 in a WCF Client?

  - by Tone

  I need to implement SAML 2.0 for a WCF client that is talking to a java web service (Glassfish). I know very little about SAML, and after a bit of searching here (and elsewhere) I do not find much about how to implement with WCF. Since WCF abstracts you away from the SOAP layer how can I add SAML assertions to the SOAP header? Will a 3rd party tool like ComponentSpace work best? Or should I roll my own? Other advice?
