• Providing downloads on ASP.net website

  - by Dave

  I need to provide downloads of large files (upwards of 2 GB) on an ASP.net website. It has been some time since I've done something like this (I've been in the thick-client world for awhile now), and was wondering on current best practices for this. Ideally, I would like: To be able to track download statistics: # of downloads is essential; actual bytes sent would be nice. To provide downloads in a way that "plays nice" with third-party download managers. Many of our users have unreliable internet connections, and being able to resume a download is a must. To allow multiple users to download the same file simultaneously. My download files are not security-sensitive, so providing a direct link ("right-click to download...") is a possibility. Is just providing a direct link sufficient, letting IIS handle it, and then using some log analyzer service (any recommendations?) to compile and report the statistics? Or do I need to intercept the download request, store some info in a database, then send a custom Response? Or is there an ASP.net user control (built-in or third party) that does this? I appreciate all suggestions.

• Replace Infinite loop in Flex

  - by H P

  Hello, I want to access a webservice:getMonitorData() , on creationcomplete and returns an array, in an infinite loop so that the getIndex0.text is updated each time. Flex is not able to handle an infinite loop and gives a timeout error 1502. If I run the for loop until i<2000 or so it works fine. How can replace the loop so that my webservice is accessed continiously and the result is shown in getIndex0.text. This is how my application looks like: <?xml version="1.0" encoding="utf-8"?> <s:Group xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300" xmlns:plcservicebean="server.services.plcservicebean.*" creationComplete="clientMonitor1()"> <fx:Script> <![CDATA[ import mx.collections.ArrayCollection; import mx.controls.Alert; import mx.rpc.CallResponder; import mx.rpc.events.FaultEvent; import mx.rpc.events.ResultEvent; [Bindable] public var dbl0:Number; //-----------Infinite Loop, Works fine if condition = i<2000------------------------ public function clientMonitor1():void{ for(var i:int = 0; ; i++){ clientMonitor(); } } public function clientMonitor():void{ var callResp:CallResponder = new CallResponder(); callResp.addEventListener(ResultEvent.RESULT, monitorResult); callResp.addEventListener(FaultEvent.FAULT, monitorFault); callResp.token = plcServiceBean.getMonitorData(); } public function monitorResult(event:ResultEvent):void{ var arr:ArrayCollection = event.result as ArrayCollection; dbl0 = arr[0].value as Number; } protected function monitorFault(event:FaultEvent):void{ Alert.show(event.fault.faultString, "Error while monitoring Data "); } ]]> </fx:Script> <fx:Declarations> <plcservicebean:PlcServiceBean id = "plcServiceBean" showBusyCursor="true" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" /> </fx:Declarations> <mx:Form x="52" y="97" label="Double"> <mx:FormItem label = "getMonitorValue"> <s:TextInput id = "getIndex0" text = "{dbl0}"/> </mx:FormItem> </mx:Form> </s:Group>

• PHP: Adding text to a file

  - by Kevin Duke

  I'm trying to set up authentication on my server, however, I know little about Php. I have a php file filled with users and passwords: function getPassword( $user ) { // the user/password database. For very small groups // of users, you may just get away with expanding this // array. $passwords= array ( 'user1' => 'password1', 'user2' => 'password2', 'user3' => 'password3', 'user4' => 'password4' ); $password = $passwords[ $user ]; if ( NULL == $password ) return NULL; Without manually editing the array of passwords, I want a php file to read in user inputs for usernames and passwords and append it to the array. I have a vague idea of how this could work by looking up documentation: <?php function fwrite_stream($fp, $string) { $fp = fopen('shit.php', 'w'); for ($written = 0; $written < strlen($string); $written += $fwrite) { $fwrite = fwrite($fp, substr($string, $written)); if ($fwrite === false) { return $written; } } return $written; fclose($fp); } ?> How do I tell this to write to the array?

• Best way to distribute form that can be printed or saved?

  - by Jason Antman

  I need to develop a simple form (intended only for printing) to be filled in by arbitrary end users (i.e. no specialized software). Ideally, I'd like the end-user to be able to save their inputs to the form and update it periodically. It seems that (at least without LiveCycle Enterprise Suite) Adobe Reader won't save data input in a PDF form. Aside from just distributing the form as a Word document, does anyone have any suggestions? Background: I do some work for a volunteer ambulance corps. They have a lot of elderly patients who don't know (or can't remember) their medical history. They want to develop a common form with personal information (name, address, DOB, medications list, etc.) for elderly residents to hang on their refrigerators (apparently a common solution to this problem). As some of them (or their children/grandchildren) are computer literate, it would make most sense to provide a download-able blank form that can be filled in, saved, updated, and re-printed as needed. Due to worries about privacy, HIPAA, etc. anything with server-side generation is out, it needs to be 100% client-side, and in a format that the majority of non-technical computer users can access without additional software. Thanks for any tips... at this point, I'm leaning towards just using a .doc form.

• application specific seed data population

  - by user339108

  Env: JBoss, (h2, MySQl, postgres), JPA, Hibernate 3.3.x @Id @GeneratedValue(strategy = IDENTITY) private Integer key; Currently our primary keys are created using the above annotation. We expect to support a large number of users (~million users), what key should be used. Should it be Integer or Long or should I use the unsigned versions of the above declarations. We have a j2ee application which needs to be populated with some seed data on installation. On purchase, the customer creates his own data on top of the application. We just want to make sure that there is enough room to ship, modify or add data for future releases. What would be the best mechanism to support this, we had looked at starting all table identifiers from a certain id (say 1000) but this mandates modifying primary key generation to have table or sequence based generators and we have around ~100 tables. We are not sure if this is the right strategy for this. If we use a signed integer approach for the key, would it make sense to have the seed data as everything starting from 0 and below (i.e -ve numbers), so that all customer specific data will be available on 0 and above (i.e. +ve numbers)

• Average over a timeframe with missing data

  - by BHare

  Assuming a table such as: UID Name Datetime Users 4 Room 4 2012-08-03 14:00:00 3 2 Room 2 2012-08-03 14:00:00 3 3 Room 3 2012-08-03 14:00:00 1 1 Room 1 2012-08-03 14:00:00 2 3 Room 3 2012-08-03 14:15:00 1 2 Room 2 2012-08-03 14:15:00 4 1 Room 1 2012-08-03 14:15:00 3 1 Room 1 2012-08-03 14:30:00 6 1 Room 1 2012-08-03 14:45:00 3 2 Room 2 2012-08-03 14:45:00 7 3 Room 3 2012-08-03 14:45:00 8 4 Room 4 2012-08-03 14:45:00 4 I wanted to get the average user count of each room (1,2,3,4) from the time 2PM to 3PM. The problem is that sometimes the room may not "check in" at the 15 minute interval time, so the assumption has to be made that the previous last known user count is still valid. For example the check-in's for 2012-08-03 14:15:00 room 4 never checked in, so it must be assumed that room 4 had 3 users at 2012-08-03 14:15:00 because that is what it had at 2012-08-03 14:00:00 This follows on through so that the average user count I am looking for is as follows: Room 1: (2 + 3 + 6 + 3) / 4 = 3.5 Room 2: (3 + 4 + 4 + 7) / 4 = 4.5 Room 3: (1 + 1 + 1 + 8) / 4 = 2.75 Room 4: (3 + 3 + 3 + 4) / 4 = 3.25 where # is the assumed number based on the previous known check-in. I am wondering if it's possible to so this with SQL alone? if not I am curious of a ingenious PHP solution that isn't just bruteforce math, as such as my quick inaccurate pseudo code: foreach ($rooms_id_array as $room_id) { $SQL = "SELECT * FROM `table` WHERE (`UID` == $room_id && `Datetime` >= 2012-08-03 14:00:00 && `Datetime` <= 2012-08-03 15:00:00)"; $result = query($SQL); if ( count($result) < 4 ) { // go through each date and find what is missing, and then go to previous date and use that instead } else { foreach ($result) $sum += $result; $avg = $sum / 4; } }

• Scalable Full Text Search With Per User Result Ordering

  - by jeremy

  What options exist for creating a scalable, full text search with results that need to be sorted on a per user basis? This is for PHP/MySQL (Symfony/Doctrine as well, if relevant). In our case, we have a database of workouts that have been performed by users. The workouts that the user has done before should appear at the top of the results. The more frequently they've done the workout, the higher it should appear in search matches. If it helps, you can assume we know the number of times a user has done a workout in advance. Possible Solutions Sphinx - Use Sphinx to implement full text search, do all the querying and sorting in MySQL. This seems promising (and there's a Symfony Plugin!) but I don't know much about it. Lucene - Use Lucene to perform full text search and put the users' completions into the query. As is suggested in this Stack Overflow thread. Alternatively, use Lucene to retrieve the results, then reorder them in PHP. However, both solutions seem clunky and potentially unscalable as a user may have completed hundreds of workouts. Mysql - No native full text support (InnoDB), so we'd have use LIKE or REGEX, which isn't scalable.

• Randomly Position A Div

  - by Connie

  I'm looking for a way to randomly position a div anywhere on a page (ONCE per load). I'm currently programming a PHP-based fantasy pet simulation game. One of the uncommon items on the game is a "Four Leaf Clover." Currently, users gain "Four Leaf Clovers" through random distribution - but I would like to change that (it's not interactive enough!). What I Am Trying To Do: The idea is to make users search for these "Four Leaf Clovers" by randomly placing this image anywhere on the page: (my rendition of a four leaf clover) I'd like to do this using a Java/Ajax script that generates a div, and then places it anywhere on the page. And does not move it once it's been placed, until the page is reloaded. I've tried so many Google searches, and the closest thing that I've found so far is this (click), from this question. But, removing the .fadein, .delay, and .fadeout stopped the script from working entirely. I'm not by any means a pro with Ajax. Is what I'm trying to do even possible?

• SharePoint Permissions: User with Contribute change cannot change a list item they did not create?

  - by antik

  I've build a custom SharePoint list that programatically adjusts permissions per list item. This part of the app works by clearing all permissions in the list item and adding permissions to the folks I want to grant Read or Contribute permission to. I believe this part of the application to be correct: selecting Manage Permissions on a list item I can see the appropriate users and roles for the list items in question in the Permissions list. However, I was surprised to realize that only the user who submitted a list item can successfully edit the item. I'll describe what I'm seeing with the following two users: UserA and UserB. UserA submitted the list item. UserB is trying to edit the same list item after the permissions have been assigned (either manually or programatically). UserB cannot edit the list item: UserB can see the Edit Item link on the item toolbar. UserB can click the link and will see EditForm.aspx. When UserB makes changes and presses submit, UserB encounters the out of box SharePoint "Access Denied" error page. The event handler for the list item update does not fire. Manually elevating UserB's permission to include Full Control does not affect the behavior above. By contrast, UserA encounters far more predictable behavior: UserA can see the Edit Item link on the item toolbar. UserA can click the link and will see EditForm.aspx. When UserA submits, the changes are persisted and the user is redirected back to the item list. Event Handlers fire after UserA submits. This leaves me with several questions: Is this an expected behavior for SharePoint that I managed to overlook? What can I do to allow UserB to modify the list item?

• node to traverse cannot be null (Hibernate SQL)

  - by tiswas

  I'm performing a SQL query through hibernate, which looks like: SELECT thi FROM track_history_items thi JOIN artists art ON thi.artist_id = art.id WHERE thi.type = "TrackBroadcast" GROUP BY art.name ORDER thi.createdAt DESC but I'm getting the message that 'Node to traverse cannot be null!'. Anyone know what could be causing this? --EDIT-- I'm pretty sure that this problem is being caused by the possibility of artist_id to be null. However, I can't prevent this, so can I just skip the rows track_history_item rows which have a null artist_id?

• Send Special Keys to Gtk.VteTerminal

  - by Ubersoldat

  Hi I have this OSS Project called Monocaffe connections manager which uses the Gtk.VteTerminal widget from PyGTK. A nice feature is that it allows the users to send commands to different servers' consoles (cluster mode) using a Gtk.TextView for the input. The way I send key strokes to each Gtk.VteTerminal is by using the feed_child method. For common keys there's no problem: I simply feed what the TextView receives to all the terminals, but when doing so with special keys I get into a little trouble. For "Return" I catch the event and feed the terminal a '\n'. For back-space is the same, catch the event and feed a '\b'. def cluster_backspace(self, widget): return self.cluster_send_key('\b') The problem comes with other keys like Tab, Arrows, Esc which I don't know how to feed as str to the terminal to recognize them. In the case of Esc is a real pain, because the users can edit the same file on different servers using vi, but cannot escape insert mode. Anyway, I'm not looking for a complete solution, just ideas since I've ran out of them. Thanks.

• Basic user authentication with records in AngularFire

  - by ajkochanowicz

  Having spent literally days trying the different, various recommended ways to do this, I've landed on what I think is the most simple and promising. Also thanks to the kind gents from this SO question: Get the index ID of an item in Firebase AngularFire Curent setup Users can log in with email and social networks, so when they create a record, it saves the userId as a sort of foreign key. Good so far. But I want to create a rule so twitter2934392 cannot read facebook63203497's records. Off to the security panel Match the IDs on the backend Unfortunately, the docs are inconsistent with the method from is firebase user id unique per provider (facebook, twitter, password) which suggest appending the social network to the ID. The docs expect you to create a different rule for each of the login method's ids. Why anyone using 1 login method would want to do that is beyond me. (From: https://www.firebase.com/docs/security/rule-expressions/auth.html) So I'll try to match the concatenated auth.provider with auth.id to the record in userId for the respective registry item. According to the API, this should be as easy as In my case using $registry instead of $user of course. { "rules": { ".read": true, ".write": true, "registry": { "$registry": { ".read": "$registry == auth.id" } } } } But that won't work, because (see the first image above), AngularFire sets each record under an index value. In the image above, it's 0. Here's where things get complicated. Also, I can't test anything in the simulator, as I cannot edit {some: 'json'} To even authenticate. The input box rejects any input. My best guess is the following. { "rules": { ".write": true, "registry": { "$registry": { ".read": "data.child('userId').val() == (auth.provider + auth.id)" } } } } Which both throws authentication errors and simultaneously grants full read access to all users. I'm losing my mind. What am I supposed to do here?

• Passing values into regex match function

• Insertion sort invariant assertion fails

• Quick and easy flood protection?

  - by James P

  I have a site where a user submits a message using AJAX to a file called like.php. In this file the users message is submitted to a database and it then sends a link back to the user. In my Javascript code I disabled the text box the user types into when they submit the AJAX request. The only problem is, a malicious user can just constantly send POST requests to like.php and flood my database. So I would like to implement simple flood protection. I don't really want the hassle of another database table logging users IPs and such... as if they are flooding my site there will be a lot of database read/writes slowing it down. I thought about using sessions, like have a session that contains a timestamp that gets checked every time they send data to like.php, and if the current time is before the timestamp let them add data to the database, otherwise send out an error and block them. If they are allowed to enter something into the database, update their session with a new timestamp. What do you think? Would this be the best way to go about it or are there easier alternatives? Thanks for any help. :)

• Which cms or script for social network wiki?

  - by Jason

  Hi, I am building a social network. I need a cms that will allow users to contribute content. Each content item will need to have a google map, list of features, ratings, comments, etc. And the content must be editable by other users with revision control. Also, each user should have a profile with their bookmarked content items, contributed items, comments, etc. It's very important that I can create a template for the wiki/content entries so that each item looks uniform. (and as a kick in the teeth, I would like to be able to search for wiki items using a radial search or map) Joomla was my first choice, as I've used it for many projects, but the wiki functionality is not there. I was also setting up a grou.ps site, but the wiki is so-so - not feature rich and it really doesn't have the option I need. Additionally, I know someone out there will mention Drupal. I may consider it if I can see it put to use without and overabundance of custom programming (I don't mind initial coding, but drupal requires constant coding & recoding - with this site, I dont' have that time commitment) I thought about using mediawiki with buddypress, but i'm not sure if that's the way to go. Thoughts?

• OOP design for DMS that allows searching and grouping

  I'd like to make a searchable Document Management System and allow a user to group documents together. On one hand, there would be a functionality that registers/fingerprints in a linear fashion and, on the other, one that associates documents into groups. How could I compromise between the two in terms of object design?

• Building a survey to put in a WordPress website using Python/Django

  - by chiurox

  So I've been given a task to build a survey to get data regarding time slot preferences of prospective students for a particular course. I know there are really quick solutions to this like Google Forms, SurveyMonkey, but since it's not unusually hard, I want to implement the survey myself in a totally new language as an opportunity to get started with it and also be able to customize and provide dynamic info to the users who are voting. Although I have done some stuff in PHP, C++, javascript, etc, I'm pretty new to Python+Django framework but it's something I've been meaning to get into since a long time ago. Initially, what I want is to make a grid with the days of the week as columns and time-durations as rows. In each cell I want to provide users a way to choose how strong (high/medium/low) their preference for this particular day+time is. I also want to show how many "votes" have already been cast for this particular preference because this will influence a lot in their decisions and as a result make this process easier when we are going to define the classes. I'll probably store the data in MySQL. Could anyone point me to some really good Python+Django tutorials for my particular purpose? Does anyone think I'm wasting my time with this trivial task by choosing new tools and that I should just use something I already know (like PHP) or a free service or plugin for Wordpress? Thanks!

• Re-authentication required for registered-path links (to ASP.NET site) coming to IE from PowerPoint

  - by Daniel Halsey

  We're using URL routing based on Phil Haack's example, with config modifications based on MSDN Library article #CC668202, to provide "shareable" links for a ASP.NET forms site, and have run into a strange issue: For users attempting to open links from PowerPoint presentations, and who have IE set as their default browser, using one of these links forces (forms-based) re-authentication, even in the same browser instance with a live session. Info: We know the session is still alive. (Page returns information for the currently logged-in user; confirmed via debug watches) This doesn't happen with other browsers (FF, Chrome) or with other programs (Notepad++) as the URL source. We do not have a default path set, as this caused issues with root path handling at initial login. This primarily happens with PowerPoint, but will also happen in Word and OCS. On some machines, even after changing the default browser, Office apps will continue to use IE for these links, forcing this error. (A potential registry fix for this failed, but even if it had worked, we can't control default browser choice for our users.) We can't figure out if this is an Office oddity or is being caused by our decision to use app-level URL routing (rather than IIS rewriting). Has anyone else encountered this and found a solution?
