• Where to register for C# events?

  - by themaninthesuitcase

  I am currently transitioning from VB to C# and am having some issues with regards to registering my interest in an event. When using VB it was simply a case of specifying that a method Handles and event, often this was generated by using the object events list. While I can easily use the Class.event += delegate in C# I am unsure where the best place is to place the code to do this. Am I best placing it inside of the InitializeComponent() as per the generated code (say if you select the event in the from designer) or should I place it inside the constructor for better readability/maintenance. If inside the constructor, should it be before or after the call to InitializeComponent()?

• what's the best (most effecient) way in asp .net to return a whole page into tabbed content?

  - by ijjo

  what i want to do is every time i click on a tab, the content area is replaced by pretty much a whole new page. i don't want a full page load so i want to do it in ajax, but i'm used to sending back small jason data via page methods. i'm not sure how i would construct a whole new page and return that via ajax and i would like to simply assign the whole content returned to a div and be done with it. what's the best way to do this with the least amount of overhead (i know there are some inefficient ways the scriptmanager does ajax)? or is it better to load the tabbed content in an iframe? fyi i'm already using jquery to call lightweight pagemethods on my asp net page and that works great.

• Automatically save CSS changes made to existing styles in Chrome dev tools?

  - by styke

  I've already mapped the necessary files to the local resource - however, while that does allow me to save any changes made to a file in the Sources panel, I was wondering if it's possible to automatically save changes to CSS made in the Elements panel. Otherwise at the moment, any changes made to the style in the Elements panel seem to exist only there. I remember at some point there used to be a little indicator of the file and line number next to a class/id etc. in the Styles tab of the Elements panel - surely it can't be that hard to simply 'update' any changes to that style rule considering Chrome knows exactly where it's coming from (in the case that it's a stylesheet and not an inline style?). It would be a great relief to my workflow. The answers to this similar question are obsolete.

• Joomla 2.5 disable and remove Smart Cache

  - by WooDzu

  I am maintaining a Joomla 2.5 based magazine website with 3-4 new, long articles every day. Smart Search was enabled by default and now I've got a few "finder" tables full of indexed phrases and therms. I wonder if there are any disadvantages if I'd: Disable the Smart Search plugin Remove these 'finder' tables completely Aha, we're using a Search field, which works fine, but I'm not sure what's going to happen if I disable the plugin and remove these tables. Will it then search for phrases in content Joomla tables or simply break w/o missing 'finder' tables Has anyone tried this before?

• Rewriting ASP.NET (.aspx) pages in Apache

  - by whitstone86

  I managed to get ASP.NET to work in Apache, as per http://weblogs.asp.net/israelio/archive/2005/09/11/424852.aspx but I'm unsure how to get it to rewrite pages, with a web.config file. I've tried using Google endlessly, but came to nothing. What's the best solution for me to rename my pages, e.g. mytestpage.aspx to mytestpage.htm Also, anyone know how to get IIS and MySQL working? I've tried but I'm struggling to get it to work. I did this simply because I needed multiple sites on port 80 on localhost, and the website I'm developing is not suited to PHP. IIS is installed, but not being used at the moment. Thanks

• Python - Why ever use SHA1 when SHA512 is more secure?

  - by orokusaki

  I don't mean for this to be a debate, but I'm trying to understand the technical rationale behind why so many apps use SHA1, when SHA512 is more secure. Perhaps it's simply for backwards compatibility. Besides the obvious larger size (128 chars vs 40), or slight speed differences, is there any other reason why folks use the former? Also, SHA-1 I believe was first cracked by a VCR's processor years ago. Has anyone cracked 512 yet (perhaps with a leaf blower), or is it still safe to use without salting?

• Perl: print back to beginning of line

  - by Pmarcoen

  Okay, so what I'm trying to do is print out a percentage complete to my command line, now, I would like this to simply 'update' the number shown on the screen. So somehow go back to the beginning of the line and change it. For example the windows relog.exe command-line utility (which can convert a .blg file to a .csv file) does this. If you run it, it will display a percentage complete. Now this is probably written in C++. I don't know if this is possible in perl as well ?

• preg_match_all confusing failing

  - by James

  $string = (string) file_get_contents($_FILES['file']['tmp_name']); echo $string; preg_match_all("/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $string, $matches); print_r($matches); I am parsing text/csv files and grabbing email addresses from uploaded files. When parsing a Google Contact file I exported it weirdly fails. But when I simply copy the string that is echo'd and paste that instead of the file_get_contents result, it parses and works. Any idea why it is refusing to take the file_get_contents string, but if I paste in the raw data myself, it works?

• Interrupt a thread in DatagramSocket.receive

  - by SEK

  I'm building an application that listens on both TCP and UDP, and I've run into some trouble with my shutdown mechanism. When I call Thread.interrupt() on each of the listening threads, the TCP thread is interrupted from listening, whereas the UDP listener isn't. To be specific, the TCP thread uses Socket.accept(), which simply returns (without actually connecting). Whereas the UDP thread uses DatagramSocket.receive, and doesn't exit that method. Is this an issue in my JRE, my OS, or should I just switch to (Datagram)Socket.close()?

• Is there any way to print the actual query that mysqli->execute() makes?

  - by 0plus1

  I have a complex query that gets executed like this: if ($stmt = $dbi->prepare($pt_query)) { $stmt->bind_param('ssssssssi', $snome,$scognome,$ssocieta,$svia,$slocalita,$sprovincia,$scap,$stelefono,$sfax,$uid); $stmt->execute(); echo $dbi->error; $stmt->close(); } else { printf("Error -> %s\n", $dbi->error); } This thing is failing without any error, it simply doesn't update the database. Since there is a ton of data that gets treated before this thing I would like to know if there is any way to show the actual query that mysqli is executing in order to understand where the problem is. Thank you.

• The best approach to customize Bootstrap Less files and keep it easy to be updated to future versions

  - by user322896

  I'm wondering what the best way would be to customize the less files in Bootstrap and, at the mean time, keep it easy to be updated to future Bootstrap versions. It's straightforward to just modify the less files, but the problem is that when the next version of Bootstrap comes out, it might be painful to upgrade (because all the changes are already deeply mixed with the original sources.) Another approach would be similar to the open closed principle, that is, keeping the original less files unchanged, and adding my customized less files to overwrite the CSS rules I need. When Bootstrap gets updated, (hopefully) I can simply replace the less files and everything would work magically. However, regardless of the correctness of my assumption, the same CSS rules would be scattered in even more places and hard to manage. Also, the more we overwrite the CSS (not for compatibility or other purposes), the more bandwidth we waste. I know this highly depends on how the author of Bootstrap would handle the structure of the framework or even the naming of CSS rules, but I'd still like to hear everybody's opinions. Thanks.

• Run sub on main thread from separate thread [VB.NET|SerialPort]

  - by Steven

  I'm reading data from a serial port, but the DataReceived event of SerialPort is handled on it's own thread. I want to handle this on the main thread, but simply declaring an event and raising it still results in it being processed on the SerialPort thread. I'm assuming I need to declare a delegate I can call, but I don't see how that would work. For example, I want to call Sub HandleDataReceived() on the main thread from the DataReceived thread, having HandleDataReceived() run on the main thread. How would I do this?

• [perl] Efficient processing of large text

  - by jesper

  I have text file that contains over one million urls. I have to process this file in order to assign urls to groups, based on host address: { 'http://www.ex1.com' = ['http://www.ex1.com/...', 'http://www.ex1.com/...', ...], 'http://www.ex2.com' = ['http://www.ex2.com/...', 'http://www.ex2.com/...', ...] } My current basic solution takes about 600mb of RAM to do this (size of file is about 300mb). Could You provide some more efficient ways? My current solution simply reads line by line, extracts host address by regex and put url into hash.

• Highly efficient filesystem APIs for certain kinds of operations

  - by romkyns

  I occasionally find myself needing certain filesystem APIs which could be implemented very efficiently if supported by the filesystem, but I've never heard of them. For example: Truncate file from the beginning, on an allocation unit boundary Split file into two on an allocation unit boundary Insert or remove a chunk from the middle of the file, again, on an allocation unit boundary The only way that I know of to do things like these is to rewrite the data into a new file. This has the benefit that the allocation unit is no longer relevant, but is extremely slow in comparison to some low-level filesystem magic. I understand that the alignment requirements mean that the methods aren't always applicable, but I think they can still be useful. For example, a file archiver may be able to trim down the archive very efficiently after the user deletes a file from the archive, even if that leaves a small amount of garbage either side for alignment reasons. Is it really the case that such APIs don't exist, or am I simply not aware of them? I am mostly interested in NTFS, but hearing about other filesystems will be interesting too.

• Open Source PHP search engine

  - by Ravi Gupta

  I am looking for an open source search engine plugin written in php for my website(eCommerce). Before anybody answer that I have a doubt regarding the search engine. Usually search engine crawl web pages, create indexes and then use them while looking for contents. But will the same model work for eCommerce websites? Yeah, it can crawl products pages, index them but don't you think it would be better if it crawls the database directly and index the products stored in the database? And when a user search for any product, it will simply give us the rows of the table which matches the user query? May be what I am asking is a stupid question but I am new to web development, so kindly help me to understand the concept. I have looked at a search engine called Sphider but didn't get what all I have to do to make it work with an eCommerce website.

• disallow certain url in robots.txt

  - by chrism

  We implemented a rating system on a site a while back that involves a link to a script. However, with the vast majority of ratings on the site at 3/5 and the ratings very even across 1-5 we're beginning to suspect that search engine crawlers etc. are getting through. The urls used look like this: http://www.thesite.com/path/to/the/page/rate?uid=abcdefghijk&value=3 When we started we add the following to our robots.txt: User-agent: * Disallow: /rate Is this incorrect or are googlebot and others simply ignoring our robots.txt?

• File System Types in .Net

  - by Avi

  I don't get the abstractions and the terminology :-( For example, DirectoryInfo.FullName is defined as the full path of the directory or file, but it's a string! So is DirectoryInfo.Name, FileInfo.FullName, Path.GetDirectoyName and so on. This means that in .Net there is no "depth" (or "meat" - my English isn't so good) for the file system objects. There's no protection from a type system. I can't, for example, define two Path objects and ask if one of them is "above" the other - I have to manipulate the strings. I can't differentiate between a Path that identifies a directory and a path that identifies a file. I can't do anything!-( Just manipulate strings. Is this correct (or am I simply missing something). If correct, are there any alternatives?

• Tag <code>: how to "correct" publish it ?

  - by stighy

  Hi, i'm not sure to explain what i'm looking for. What's the name of the "source code parser" for publish code, in HTML ? For example, when i write some source code here in stack overflow, system auto-detect the sintax and write "correct" source code in html. I've noticed that exists the HTML <"code" tag, but it simply write source code in "courier" font. So i'm asking you if exists some "external" component that, given a text, parse it out correctly in a HTML page. Thank you!

• How to connect Model through Controller to View using bindings?

  - by Paperflyer

  I have an NSTextField in my view. Its value is bound to an NSNumber *number in my controller. The controller simply calls through to the model (value) to get the appropriate value. // In the controller - (NSNumber *)number { return [NSNumber numberWithFloat:[model value]]; } - (void)setNumber:(NSNumber *)aNumber { [model setValue:[aNumber floatValue]]; } This is fine, only the controller is not notified of model changes and thus, changing the value in the model does not update the NSTextField. The only other option I can think of is to have the model notify the controller and the controller manually update the view through an Outlet. But this circumvents the binding. // In the model, after value change [[NSNotificationCenter defaultCenter] postNotificationName:@"ValueChanged" object:self]; // In the controller, after being notified - (void)updateView:(NSNotification *)aNotification { [myTextField setFloatValue:[model value]]; } Is there a better, binding-aware way to implement this communication?

• Error comparing hash to hashed mysql password (output values are equal)

  - by Charlie

  Im trying to compare a hashed password value in a mysql database with the hashed value of an inputted password from a login form. However, when I compare the two values it says they aren't equal. I removed the salt to simply, and then tested what the outputs were and got the same values $password1 = $_POST['password']; $hash = hash('sha256', $password1); ...connect to database, etc... $query = "SELECT * FROM users WHERE username = '$username1'"; $result = mysql_query($query); $userData = mysql_fetch_array($result); if($hash != $userData['password']) //incorrect password { echo $hash."|".$userData['password']; die(); } ...other code... Sample output: 7816ee6a140526f02289471d87a7c4f9602d55c38303a0ba62dcd747a1f50361| 7816ee6a140526f02289471d87a7c4f9602d55c38303a0ba62dcd747a1f50361 Any thoughts?

• Old functions return 'undefined' error once I add a jquery reference

  Disregard this question: I've simply confused <script src="..."></script> tag and <script> [some functions] </scipt> tags. I have this function function OnLoad() { ShowHideConfirmAnswers(); return true; } triggered by onload event: <body onload=OnLoad()> It works fine until I add src="jquery-1.4.2.js" to the script element. From this moment I get "OnLoad is not defined" error, and the same happens to every other javascript function.
