  • How do I clear MVC client side validation errors when a cancel button is clicked when a user has inv

    - by Sci-fi
    I have a partial view that is rendered within a main view. The partial view takes advantage of System.ComponentModel.DataAnnotations and Html.EnableClientValidation(). A link is clicked, and div containing the partial view is displayed within a JQuery.Dialog(). I then click the save button without entering any text in my validated input field. This causes the client side validation to fire as expected, and display the '*required' message beside the invalid field. When the cancel button is clicked, I want to reset the client side MVC validation back to it's default state and remove any messages, ready for when the user opens the dialog again. Is there a recommended way of doing this?

  • Run a proc on several different values of one parameter

    - by WEFX
    I have the following query that gets run within a proc. The function MyFunction returns a table, and this query joins on that table. This proc works great when a @MyArg value is supplied. However, I’m wondering if there’s a way to run this on all @MyArg values in the database. I’m sure there’s a way to do it within a loop, but I know that loops are generally to be avoided at the db layer. I really just need to perform this for the sake of checking (and possibly cleansing) some bad data. SELECT ColumnA, ColumnB, ColumnC FROM ( SELECT a.ColumnA, a.ColumnB, a.ColumnC, ROW_NUMBER() over(partition by a.ColumnD order by f.ColumnX) as RowNum FROM dbo.MyTableA AS a INNER JOIN dbo.MyFunction(@MyArg) f ON f.myID = a.myID WHERE (a.myBit = 1 OR a.myID = @MyArg) ) AS x WHERE x.rownum = 1;

  • iptables firewall to protect against automated entries

    - by Kenyana
    I am getting unusually large calls on my app. I have implemented CSRF Check over ajax and its working but am still getting so many calls. My guess is that someone has a script that is 'logged' in and making all these calls. Could someone please share a good iptables script for blocking ip's that run 10 calls to /controler/action in a second. I am using `/sbin/iptables -A INPUT -p tcp --syn --dport $port -m connlimit --connlimit-above N -j REJECT --reject-with tcp-reset save the changes see iptables-save man page, the following is redhat and friends specific command service iptables save` That is from cyberciti

  • Windows/C++: detect when focus has changed between windows (globally)

    - by twig
    I'm trying to find a way to detect when focus is changed to another window (without having to poll every X ms). I've already figured out a way to detect when focus is switched between applications using WH_SHELL and HSHELL_ACTIVATESHELLWINDOW. The problem is I want to detect when focus is switched between dialog/windows within the same app. ie. In Notepad, I can determine when the app switches to Notepad, but I cannot detect when the "Open" or "Save" dialogs appear because the focus is still within the same application.

  • NoMethodError when trying to invoke helper method from Rails controller

    - by John Topley
    I'm getting a NoMethodError when trying to access a method defined in one of my helper modules from one of my controller classes. My Rails application uses the helper class method with the :all symbol as shown below: class ApplicationController < ActionController::Base helper :all . . end My understanding is that this should make all of my controller classes automatically include all of the helper modules within the app/helpers directory, therefore mixing in all of the methods into the controllers. Is this correct? If I explicitly include the helper module within the controller then everything works correctly.

  • How to use GPS data like the double value returned by getLatitude()?

    - by Dan
    I have been searching quite a bit for an answer, but maybe I'm just not using the correct terminology. I am creating an app that will access a database to return a list of other users that are within a certain distance of the users location. I've never worked with this type of data, and I don't really know what the values mean. I'd like to do all the calculations on the backend with either MySQL or PHP. Currently, I am storing the latitude and longitude as doubles within the database. I can access them and store them, but I have no idea how I might be able to sort them based on distance. Perhaps I should be using a different type or some technique that is common in this area. TIA.

  • Forwarding activity result to parent, with singleTop launch mode

    - by Joe
    I have two activities: a MainListActivity, and a DetailViewActivity. DetailViewActivity is set with android:launchMode="singleTop". When clicking an item in the "main list" activity, it launches the "detail view" activity via: startActivityForResult(detailIntent, REQUEST_CODE_DETAIL); If I then call setResult(RESULT_OK, resultData); and finish(); from within the Detail activity, that resultData is received by the "main list" activity's onActivityResult(..) method correctly. However, if I implement a "see previous"/"see next" type of navigation within the Detail activity, and implement it using singleTop, that result no longer gets sent back to the initial activity: Intent nextItemIntent = this.createIntent(nextId); nextItemIntent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT); startActivity(nextItemIntent); // at this point, my DetailActivity's onNewIntent() method is called, and the new data is loaded properly But from here, when I call setResult(..) and finish(), my MainList activity never receives the new/updated result. Anyone know what I'm doing wrong?

  • Query to work out possible destinations on a set of routes using SQL Server 2008

    - by RobW
    I'm writing an application that models train routes, which are stored in the database table [TrainStop] as follows: RouteId StationCode StopIndex IsEnabled So a given route consists of several rows with the StopIndex indicating the order. The problem I am trying to solve is to say which stations a user can get to from a given starting station. This would be relatively straightforward BUT it is also possible to disable stops which means that a user cannot get to any destinations after that stop. It is also possible that multiple routes can share stations e.g.: Route 1: A, B, C, D, E Route2: P, Q, B, C, D, R So if a user is at B they can go to C, D, E and R but if station D is disabled they can get to C only. Solving this problem is fairly straightforward within C# but I am wondering whether it can be solved elegantly and efficiently within SQL? I'm struggling to find a way, for each route, to rule out stations past a row that is not enabled.

  • MySQL Hibernate sort on 2 columns

    - by sammichy
    I have a table as follows Table item { ID - Primary Key content - String published_date - When the content was published create_date - When this database entry was created } Every hour (or specified time interval) I run a process to update this table with data from different sources (websites). I want to display the results according to the following rules. 1. The entries created each time the process runs should be grouped together. So the entries from the 2nd process run will always be after the entries from the first process run even if the published_date of an entry from the first run is after the published_date of an entry from the 2nd run. 2. Within the grouping by run, the entries by sorted by published_date 3. Another restriction is that I prefer that data from the same source not be grouped together. If I do the sort by create_date, published_date I will end up with data from source a, data from source b etc. I prefer that the data within each hour be mixed up for better presentation If I add a column to this table and store a counter which increments each time the process is run, it is possible to create a query to sort first by counter and then by published_dt. Is there a way to do it without adding a field? I'm using Hibernate over MySQL. e.g. Hour 1 (run 1) 4 rows collected from site a (rows 1-4) 3 rows collected from site b (rows 5-7) hour 2 (run 2) 2 row collected from site a (rows 8-9) 3 rows collected from site b (rows 10-12) ... After each run, new records are added to the database from each website. The create date is the time when the record was created in the database. The published date is part of the content and is read in from the external source. When the results are displayed I would like rows to be grouped together based on the hour they were published in. So rows 1-7 would be displayed before rows 8-12. Within each hourly grouping, I would like to sort the results by published date (timestamp). This is necessary so that the posts from all the sites collected in that hour are not grouped together but rather mixed in with each other.

  • Commenting system for CakePHP blog tutorial

    - by Ryan
    I'm building off the CakePHP tutorial for the blog engine by adding comments to each post. I am able to add comments by selecting the post that it should be attached to, via a select box. I would like to be able to click an "Add Comment" link within the post and have the association to the post formed programatically. I am unsure how I can pass the post_id to the add method within my comments_controller. The body of my add method is the auto-generated scaffold code. Is it as easy as adding a $postId argument to the add method and write this to the post_id in my comments model? This doesn't feel right though, since I would expect add to be called when my submit button is click on my comments add view. Thanks all.

  • Initialize array in O(1) -- how is this trick called?

    - by user946850
    There is this pattern that trades performance of array access against the need to iterate it when clearing it. You keep a generation counter with each entry, and also a global generation counter. The "clear" operation increases the generation counter. On each access, you compare local vs. global generation counters; if they differ, the array has been reset. This has come up in StackOverflow recently, but I don't remember if this trick has an official name. Does it? One use case is Dijkstra's algorithm if only a tiny subset of the nodes has to be relaxed, and if this has to be done repeatedly.

  • What are the differences in performance between synchronous and asynchronous JavaScript script loading?

    - by jasdeepkhalsa
    My question is simply: what are the differences in performance between synchronous and asynchronous JavaScript script loading? From what I've gathered synchronous code blocks the loading of a page and/or rest of the code from executing. This happens at two levels. First, at the level of the script actually loading, and secondly, within the JavaScript code itself. For example, on the page: Synchronous: <script src="demo_async.js" type="text/javascript"></script> Asynchronous: <script async src="demo_async.js" type="text/javascript"></script> And within a script: Synchronous: function a() {alert("a"); function b() {alert("b");}} Asynchronous (and self-executing): (function(a, function(b){ alert(b); }) { alert(a); }))(); So what really is the difference in performance from using these different loading methods and JavaScript patterns?

  • Android sql creating database once

    - by semajhan
    One thing i'm not understanding is how to create the database and data just once in an android application. I extend SQLiteOpenHelper and use a DataHelper class that to manipulate data. Now, I have addEvent() and updateEvent() within the DataHelper class. I create an instance of DataHelper in my Activity and addEvent() a couple of times to insert data. Well, now I don't know how to just do that once. If I restart the app, its just going to "addEvent()" again and so the data is being reset every time. Sorry for the probably really REALLY noob question. The only solution I found was not using the DataHelper class and just adding data "manually" within the onCreate() method in SQLiteOpenHelper.

  • Settings messed up after crash

    - by ChocoDeveloper
    After an abrupt shutdown many settings were messed up: #1 Firefox was a mess. Bookmarks were gone, and I couldn't even add new ones. I had to reset firefox from safe mode and install all my addons and configure everything. This was a pain but is now solved. #2 The background in the login screen shows the one I chose with Ubuntu Tweak for a second, and then it puts back the default one. I tried changing it again with Ubuntu Tweak but it's still happening. #3 All my shortcuts in the sidebar were replaced by the default ones. I re-added them manually, also a pain. So how can I solve 2? And in case this happens again, is there a way to fix everything easy and fast?

  • Hide 'Would you like to remember password' iFrame

    - by nsilva
    Basically I have a website called http://yellow-taxis.uk/ which features an online booking system that is placed on the web site within an iFrame. On the online booking, it automatically logs the user in as a 'Guest' for credit card payments. When the site loads it comes up with a window asking the viewer if they 'would like to remember the password'. I was wondering if there was anyway possible to not display this window as it would be a much simpler option than changing a lot of the code within the online booking. Just to add, the iFrame is hosted on the same server as the web site (not sure if this makes a difference) Any help would be much appreciated.

  • Securing paths in PHP

    - by tjm
    I'm writing some PHP which takes some paths to different content directories, and uses these to include various parts of pages later. I'm trying to ensure that the paths are as they seem, and none of them break the rules of the application. I have PRIVATEDIR which must lie above DOCUMENT_ROOT (aka) PUBLICDIR. CONTENTDIR which must lie within PRIVATEDIR and not go back below PUBLICDIR and some other *DIR's which must remain within CONTENTDIR. Currently I set up some defaults, and then override the ones the user specifies and then sanity check them with the following. private function __construct($options) { error_reporting(0); if(is_array($options)) { $this->opts = array_merge($this->opts, $options); } if($this->opts['STATUS']==='debug') { error_reporting(E_ALL | E_NOTICE | E_STRICT); } $this->opts['PUBLICDIR'] = realpath($_SERVER['DOCUMENT_ROOT']) .DIRECTORY_SEPARATOR; $this->opts['PRIVATEDIR'] = realpath($this->opts['PUBLICDIR'] .$this->opts['PRIVATEDIR']) .DIRECTORY_SEPARATOR; $this->opts['CONTENTDIR'] = realpath($this->opts['PRIVATEDIR'] .$this->opts['CONTENTDIR']) .DIRECTORY_SEPARATOR; $this->opts['CACHEDIR'] = realpath($this->opts['PRIVATEDIR'] .$this->opts['CACHEDIR']) .DIRECTORY_SEPARATOR; $this->opts['ERRORDIR'] = realpath($this->opts['CONTENTDIR'] .$this->opts['ERRORDIR']) .DIRECTORY_SEPARATOR; $this->opts['TEMPLATEDIR' = realpath($this->opts['CONTENTDIR'] .$this->opts['TEMPLATEDIR']) .DIRECTORY_SEPARATOR; // then here I have to check that PRIVATEDIR is above PUBLICDIR // and that all the rest remain within private dir and don't drop // down into (or below) PUBLICDIR again. And die with an error if // they don't conform. } The thing is this seems like a lot of work to do, especially as it must be run, every time a page is accessed, before I can do anything else, e.g check for a cached version of the page I'm serving. Part of me is thinking, since all of these paths are predefined by the maintainer of the site, they SHOULD be aware of what paths they are allowing access to and ensuring they are secure. But, I think I'm thinking that because currently I am said maintainer, and I KNOW my paths conform to the rules. That said, I do want to secure this thing from any accidental errors by future maintainers (and I bet, now I've said above "I KNOW...", probably from myself somewhere down the line). This just feels like a suboptimal solution. I wonder how fast this would really be and what you would suggest to improve it or as an alternative? Thanks.

    Hello all, I have been reading StackOverflow for a while and now I have a question I cannot find an answer to. i am trying to fade a background and increase on img size on rollover. I have tried animate() and fadeTo(), however, the entire div fades. Do I need to absolute position my images over the div and not within it? img or img? Is that the only way to get items within a div to not fade along with the background? Thanks! Jason

  • UITextView or UIWebView with normal words looking like links

    - by diwup
    Hey guys, I was looking at the Twitter for iPhone app and was puzzled. First of all, there are normal words looking like links inside. Second, when I touch those link-like words, the text view (or maybe web view) jumps to the corresponding part below (yes, it doesn't open Safari, it just jumps to the text within that text/web view) Now I want to implement the same effects. I should base my implementation on what? UITextView or UIWebView? How to make normal words look like links? How to make those smooth jumps within such a text/web views? Thanks in advance.

  • how to pass variable arguments from one function to other in tcl

    - by vaichidrewar
    I want to pass variable arguments obtained in one function to other function but I am not able to do so. Function gets even number of variable arguments and then it has to be converted in array. Below is the example. Procedure abc1 gets two arguments (k k) and not form abc1 procedure these have to be passed to proc abc where list to array conversion it to be done. List to array conversion works in proc1 i.e. abc1 but not in second proc i.e. abc Error obtained is given below proc abc {args} { puts "$args" array set arg $args } proc abc1 {args} { puts "$args" array set arg $args set l2 [array get arg] abc $l2 } abc1 k k abc k k Output: k k {k k} list must have an even number of elements while executing "array set arg $l1" (procedure "abc" line 8) invoked from within "abc $l2" (procedure "abc1" line 5) invoked from within "abc1 k k" (file "vfunction.tcl" line 18)

    I have a Google Engage account, which keeps showing me: Your Google Account has changed The email address on your Google Account has changed. The account that controls your Engage membership now has an email address of: fasheikh15%[email protected]. How can I fix this? Go to the sign-in page: Sign In Log in with your normal password but instead use the following email address: myemailadd%[email protected] You will then be given the option to switch your Engage member profile to: [email protected]. If you wish to do this then just follow the on-screen instructions when you get to the Switch Accounts page. I've been contacting them since April to no avail so I thought I'd see if anyone here has any fixes?

  • What is the best businessmodel when using NHibernate to access the database?

    - by Sem Dendoncker
    Hi, I'm starting to use NHiberante as a dataaccess tier. I'm used to work with the repository model as a business model. This means, my domain model (not really a tier), my asp.net application tier, my repository tier which finally uses my dataaccess tier. But with what I've learned by now (on NHibernate) I know that many logic is done within an ISession so I was wondering if NHibernate could be used within the repository tier. Or perhaps there are even better ways to use NHibernate. Does anyone know where I could find a propriate example of how to use NHibernate in an webapplication? Cheers, M.
