• Will the changes of a property in a "StaticResource instance" reflected in UI ?

  - by Anish

  I have used object data provider to create instance of my view-model as below: <ObjectDataProvider x:Key="Datas" ObjectType="{x:Type ViewModel:UserControlViewModel}"> </ObjectDataProvider> <DataTemplate x:Key="SourceGrid"> <WPFToolKit:DataGrid x:Name="SourceDataGrid" ItemsSource="{Binding Source={StaticResource Datas},Path=SourceGridData}" CanUserSortColumns="True" GridLinesVisibility="None" IsSynchronizedWithCurrentItem="True" SelectionUnit="FullRow"></WPFToolKit:DataGrid> </DataTemplate> My question is... as I am using the instance - "Datas" as staticResource, will the changes to the property "SourceGridData" get reflected in UI? ItemsSource="{Binding Source={StaticResource Datas},Path=SourceGridData}" `

• Querying Active Directory in ruby app on Windows box

  - by Ben

  I have a small ruby app in which I'm trying to query some information from Active Directory. The app will be run by a Windows user who is already logged in. It looks like the ruby-net-ldap gem wants me to connect to an LDAP server using an IP address, port and then pass my username and password. Is there a way to achieve this (with a different gem, say) so that I don't have to pass this information (I don't have the current user's password for example, so that's not going to work)? I'm also hosting a Trac website on our intranet (which is written in Python if I remember correctly and that seems to know the current Windows username and domain. If it can do it, surely my little ruby app can access this information too?

• Active Directory on local server and intranet on external server.

  - by cvack

  I have a local Active Directory server and a external web server where my intranet is located. $ad = ldap_connect("ldap://ip-address") or die("Couldn't connect to AD!"); ldap_set_option($ad, LDAP_OPT_PROTOCOL_VERSION, 3); $bd = ldap_bind( $ad, "user@domain", "password") or die("Can't bind to server."); When I run this on a local web server it succesfully binds the connection. If I run the same code on the external server its unable to bind the ldap connection. Both port 389 and 636 is open on the AD server. I've tried google for an answer, but all the tutorials is for Active Directory and webserver on the same server. Is this even possible?

• passing multiple queries to view with codeigniter

  - by LvS

  I am trying to build a forum with Codeigniter. So far i have the forums themselves displayed and the threads displayed, based on the creating dynamic news tutorial. But that is 2 different pages, i need to obviously display them into one page, like this: Forum 1 - thread 1 - thread 2 - thread 3 Forum 2 - thread 1 - thread 2 etc. And then the next step is obviously to display all the posts in a thread. Most likely with some pagination going on. But that is for later. For now i have the forum controller (slimmed version): <?php class Forum extends CI_Controller { public function __construct() { parent::__construct(); $this->load->model('forum_model'); $this->lang->load('forum'); $this->lang->load('dutch'); } public function index() { $data['forums'] = $this->forum_model->get_forums(); $data['title'] = $this->lang->line('title'); $data['view'] = $this->lang->line('view'); $this->load->view('templates/header', $data); $this->load->view('forum/index', $data); $this->load->view('templates/footer'); } public function view($slug) { $data['forum_item'] = $this->forum_model->get_forums($slug); if (empty($data['forum_item'])) { show_404(); } $data['title'] = $data['forum_item']['title']; $this->load->view('templates/header', $data); $this->load->view('forum/view', $data); $this->load->view('templates/footer'); } } ?> And the forum_model (also slimmed down) <?php class Forum_model extends CI_Model { public function __construct() { $this->load->database(); } public function get_forums($slug = FALSE) { if ($slug === FALSE) { $query= $this->db->get('forum'); return $query->result_array(); } $query = $this->db->get_where('forum', array('slug' => $slug)); return $query->row_array(); } public function get_threads($forumid, $limit, $offset) { $query = $this->db->get_where('thread', array('forumid', $forumid), $limit, $offset); return $query->result_array(); } } ?> And the view file <?php foreach ($forums as $forum_item): ?> <h2><?=$forum_item['title']?></h2> <div id="main"> <?=$forum_item['description']?> </div> <p><a href="forum/<?php echo $forum_item['slug'] ?>"><?=$view?></a></p> <?php endforeach ?> Now that last one, i would like to have something like this: <?php foreach ($forums as $forum_item): ?> <h2><?=$forum_item['title']?></h2> <div id="main"> <?=$forum_item['description']?> </div> <?php foreach ($threads as $thread_item): ?> <h2><?php echo $thread_item['title'] ?></h2> <p><a href="thread/<?php echo $thread_item['slug'] ?>"><?=$view?></a></p> <?php endforeach ?> <?php endforeach ?> But the question is, how do i get the model to return like a double query to the view, so that it contains both the forums and the threads within each forum. I tried to make a foreach loop in the get_forum function, but when i do this: public function get_forums($slug = FALSE) { if ($slug === FALSE) { $query= $this->db->get('forum'); foreach ($query->row_array() as $forum_item) { $thread_query=$this->get_threads($forum_item->forumid, 50, 0); } return $query->result_array(); } $query = $this->db->get_where('forum', array('slug' => $slug)); return $query->row_array(); } i get the error A PHP Error was encountered Severity: Notice Message: Trying to get property of non-object Filename: models/forum_model.php Line Number: 16 I hope anyone has some good tips, thanks! Lenny *EDIT*** Thanks for the feedback. I have been puzzling and this seems to work now :) $query= $this->db->get('forum'); foreach ($query->result() as $forum_item) { $forum[$forum_item->forumid]['title']=$forum_item->title; $thread_query=$this->db->get_where('thread', array('forumid' => $forum_item->forumid), 20, 0); foreach ($thread_query->result() as $thread_item) { $forum[$forum_item->forumid]['thread'][]=$thread_item->title; } } return $forum; } What is now next, is how to display this multidimensional array in the view, with foreach statements.... Any suggestions ? Thanks

• Parsing XML with jQuery

  I've used this: $(document).ready(function () { $.ajax({ type: "GET", url: "http://domain.com/languages.php", dataType: "xml", success: xmlParser }); }); function xmlParser(xml) { $('#load').fadeOut(); $(xml).find("result").each(function () { $(".main").append('' + $(this).find("language").text() + ''); $(".lang").fadeIn(1000); }); } I used a local XML file on my computer, it works fine, but when I change the URL to an website, it just keeps loading all the time... How do I get this to work?

• RadioGroup getValue does not return correct slected value

  - by vagabond

  I'm running into a small issue with RadioGroup. My RadioGroup has possible values, true and false. The Radio types I have in my radiogroup use a Model that stores true or false. On an ajax onchange event I want to do some handling, and to do so I need to know the selected radio in my radiogroup and another identical radiogroup. The problem is getValue() only returns the initial value from my Pojo. Whenver I click on a radio button to change the selected Radio getValue() still returns the initial value. When I save my changes, my Pojo gets the correct value. I am finding this bizarre and have spent hours trying to figure our what I'm missing.

• Paperclip + ImageMagick on Windows 7: Image display fails when I add styles to attached_file in mode

  - by Brian Roisentul

  I'm working with Ruby on rails 2.3.8, NetBeans IDE. I've installed paperclip and I could show/save images successfully. Now, I've installed ImageMagick-6.6.2-4-Q16(for windows 7, 64bits). Until that moment, my model looked like this(and worked fine): has_attached_file :photo Now, after installing ImageMagick, when I add the :style line it fails: has_attached_file :photo, :styles => {:thumb => "100x100#", :small => "150x150>", :large => "400x400>" } and it throws the following error message when I try to upload an image: TypeError in ProfilesController#update backtrace must be Array of String The only thing I'm doing in the update action of that controller is the following: @profile.update_attributes(params[:profile]) @profile.update_attribute(:photo, params[:profile][:photo]) I've also installed miniMagick gem(because I read somewhere I had to do it). What am I missing?

• Access Codeigniter database functions from file

  Hello. I am using a SWFupload script and I can't make a request from flash with mod_rewrite, I don't know why... I just need to point the Flash request to that file directly.

Thanks.

• Rails: Converting from MySQL to PostGres breaks Geokit Distance Calculations???

  - by Kevin

  I recently switched my database from MySQL to PostGres. I also use GeoKit. When I started my app up with the new database already seeded, I get the following error: PGError: ERROR: function radians(character varying) does not exist LINE 1: ...COS(0.661045389762993)*COS(-2.12957994527573)*COS(RADIANS(ti... ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. Anyone know why this is breaking now? I know GeoKit still works because it's still performing the geocoding in the model per ticket when the database is seeded, it just won't do the distance calculations correctly.

• Mozilla Firefox border rendering

  - by zA

  Hi, I've come across a strange thing in Firefox, which has become a problem to me. It seems that Firefox renders borders thinner than other browsers. For example I have just a simple empty div element, and nothing else on the webpage, with a border set to width:3px. In all other browsers, such as IE, Opera, Chrome and Safari, the width looks the same and is in fact 3px wide. But in Firefox I noticed that the border width seemed thinner. So I checked the border width with Firebug, under the Computed tab - Box model. And yes as I suspected, the rendered border in Firefox is thinner. The border width that Firefox rendered is actually 2.2px and not the expected 3px. This small difference with Firefox completely messes up my design. Has anyone else noticed this? Does anyone have a solution for this? Thanks in advance!

• sql server replication algorithm.

  - by reggie

  Anyone know how the underlying replication model in sql server works? Do they essentially depend on UTC datetime values to determine if something is new or do they keep a table of all the changes (like a table of tableID+rowid that have changed). I am building my own "replication" system and was planning on using the dates to know what to replicate. Then I started wondering what would happen if the date got off in the computer for some reason. The obvious choice is to keep a log of the changes as you go and once you replicate those changes, you remove from the log of changes. But thats a lot of extra work, instead of just checking dates. I figure if sql server replication works by just checking the dates, then that should be good enough for me. Any wisdom here? thanks

• Change Gmail message routing on individual mailboxes

  - by citadelgrad

  We are using dual delivery for one of our Google Apps doamins and need to be able to disable mail delivery to the Gmail account. You can manually update the settings on a per user basis through the Admin interface by unchecking the box next to "Google Apps Email" in the Email routing section. From the Google Apps API documentation for the python library it does not appear that I programmatically disable the email routing for "Google Apps Email" on a per user basis. Does anyone know if it's possible? The only routing related method I can find is at the Domain level and not the user level. gdata.apps.adminsettings.service Thank you!

• Differences in MS Office Charts

  - by simendsjo

  I'm about to do some Office integration creating charts from some data-sources and adding them to PPT slides. But some coworkers are saying using PPT charts is suboptimal as they are missing features of Excel charts, and are different in many ways. They're unable to come up with examples, and so am I... I found the following blog about Office2007, saying there are some differences in the programming model, but that they all use the same underlying engine. Are there really any differences in the capabilities of the charts? Is it mostly UI issues? What features are different/missing from PPT charts? Are these issues resolved in Office2010?

• Django: switch language of message sent from admin panel

  - by yoshi

  I have a model, Order, that has an action in the admin panel that lets an admin send information about the order to certain persons listed that order. Each person has language set and that is the language the message is supposed to be sent in. A short version of what I'm using: from django.utils.translation import ugettext as _ from django.core.mail import EmailMessage lang = method_that_gets_customer_language() body = _("Dear mister X, here is the information you requested\n") body += some_order_information subject = _("Order information") email = EmailMessage(subject, body, '[email protected]', ['[email protected]']) email.send() The customer information about the language he uses is available in lang. The default language is en-us, the translations are in french (fr) and german (de). Is there a way to use the translation for the language specified in lang for body and subject then switch back to en-us? For example: lang is 'de'. The subject and body should get the strings specified in the 'de' translation files.

• How can I by using the FormHelper ,or some other method, render an image link that runs javascript w

  - by chiggsy

  Background: I want to render this: <a href="javascript:myfunction('Somevar')"><img src="some.png" width="20" height="20" border="0" /></a> in a cakephp app. Note: this link is not associated with a model at all, it's just part of a form going off-site. I'm unsure of how to proceed: I've seen this on the cakephp site, but with all that goes on in cake, I'm not sure about the whole javascript calling business. What's the best way to create such a thing?

• Where to store things like user pictures using Azure? Blob Storage?

  - by n26

  I have just migrated a project of mine for test cases to Microsoft's azure. But for functionalities similar to an avatar upload I need write access to the files on the harddrive. But this is a cloud, so this is not possible. How can I build such functionalities instead? Should I use the Blob Storage or is there a better solution? Does it make sense to store all website images (f.e. layout images) in the Blob Storage? So I would have a Cookie-free Domain for my static content?

• How do I find where id does not match any of an array?

  - by Nick5a1

  I have a Workout model that has and belongs to many Equipment models. I have an array of some Equipment IDs. I want to find all Workouts that don't have any Equipment assigned that matches any of the array of Equipment IDs. So, if my array = [2,3,5] I want to find all workouts where the assigned equipment ids does not include 2, 3 or 5. EDIT: Workout.joins(:equipment).where("equipment.id not in(?)",[2,3,5]).uniq Assuming five instances of Equipment, the code above returns workouts with equipment.ids 1 and 4 (good), but also returns partial matches for example Workouts with equipment.id = [1,2], [1,2,3].

• How to always return a set number of records when using find_related_tags with acts-as-taggable-on

  - by hadees

  I'm using the acts-as-taggable-on gem and I need to use find_related_tags on my survey model to get back 3 surveys every time. In the event there aren't always 3 related I need to pick how ever many are related plus some random ones to get to 3. Additionally I have a method I wrote called completed_survey_ids which return an array of survey_ids that shouldn't be used because the user has already completed them. Also there is a rare case that there won't be enough surveys because the user has completed them all so in that event it is okay to return less surveys then requested. I did write a named_scope to handle getting rid of the completed_survey_ids that I think works named_scope :not, lambda { |survey_ids| {:conditions => "id NOT IN (#{survey_ids.join(',')})" } }

• Best option for Google App Engine Datastore and external database?

  - by Alex

  I need to get an App Engine app talking to and sharing data with an external database, The best option i can come up with is outputting the external database data to an xml file and then processing this in my app engine app and storing it inside the datastore, although the data being shared is sensitive data such as login details so outputting this to an xml file is not exactly a great idea, is it possible for the app engine app to directly query the database? or is there a secure option for using xml files? oh and im using python/django and the external database will be hosted on another domain

• OpenGL Performance Questions

  - by Daniel

  This subject, as with any optimisation problem, gets hit on a lot, but I just couldn't find what I (think) I want. A lot of tutorials, and even SO questions have similar tips; generally covering: Use GL face culling (the OpenGL function, not the scene logic) Only send 1 matrix to the GPU (projectionModelView combination), therefore decreasing the MVP calculations from per vertex to once per model (as it should be). Use interleaved Vertices Minimize as many GL calls as possible, batch where appropriate And possibly a few/many others. I am (for curiosity reasons) rendering 28 million triangles in my application using several vertex buffers. I have tried all the above techniques (to the best of my knowledge), and received almost no performance change. Whilst I am receiving around 40FPS in my implementation, which is by no means problematic, I am still curious as to where these optimisation 'tips' actually come into use? My CPU is idling around 20-50% during rendering, therefore I assume I am GPU bound for increasing performance. Note: I am looking into gDEBugger at the moment Cross posted at Game Development

• Control Menu Items based on Privileges of Logged In User with spring security

  - by Nirmal

  Hi All... Based on this link I have incorporated the spring security core module with my grails project... I am using the Requestmap concept by storing each role, user and requestmap inside the database only... Now my requirement is to provide the menu items based on the users assigned roles... For e.g.: If my "User" Main Menu have following Items : Dashboard Import User Manage User And if I have assigned a roles of Dashboard and Import User to the user with a username "auditor" then, only following Menu items should be displayed on the screen : User (Main Menu) - Dashboard (sub menu) - Import User (sub menu) I have explored the Spring Security ACL plugin for the same, but it's using the Domain classes to get it working... So, wanted to know the convenient way to do so... Thanks in advance...
