• Cannot run setups from a vboxsvr mapped network drive on Windows 7 within VirtualBox

  - by Dimitri C.

  I'm trying to run an application setup by double-clicking the setup.exe from within Windows Explorer. The file is located on a mapped network drive, and I'm using Windows 7. This results in the following error message: The specified path does not exist. Check the path, and then try again. The workaround I found is to copy the installer to the main hard drive (c:) and run it from there; however, this is rather inconvenient. The same action did work on Windows 2000, Windows XP and Windows Vista. I have the impression that the problem only occurs with installers, as everything seemed to work fine with regular exe's. Is there anyone who can explain this odd behavior? Update: After some extended tests I noticed that the problem only occurs with a mapped drive of VirtualBox's "shared folders" (cf. vboxsvr). Mapping an SMB drive works fine.

• paperclip callbacks or simple processor?

  - by holden

  I wanted to run the callback after_post_process but it doesn't seem to work in Rails 3.0.1 using Paperclip 2.3.8. It gives an error: undefined method `_post_process_callbacks' for #<Class:0x102d55ea0> I want to call the Panda API after the file has been uploaded. I would have created my own processor for this, but as Panda handles the processing, and it can upload the files as well, and queue itself for an undetermined duration I thought a callback would do fine. But the callbacks don't seem to work in Rails3. after_post_process :panda_create def panda_create video = Panda::Video.create(:source_url => mp3.url.gsub(/[?]\d*/,''), :profiles => "f4475446032025d7216226ad8987f8e9", :path_format => "blah/1234") end I tried require and include for paperclip in my model but it didn't seem to matter. Anyideas?

• How to detect a background program (in Windows 7) which takes active focus automatically?

  - by Sachin Shekhar

  A background process/program steals focus from my currently active application. It disturbs me a lot when I type in an app or control an app using keyboard or play online flash games in full-screen. I want to remove this program from my PC, but I'm unable to detect it. I've analyzed all processes & scanned for viruses. All things are right from this side. I don't want to change focus behavior using registry tweak. Please, help me detecting that app..

• Retrieve Table Row Index of Current Row

  - by Jon

  Hi Everyone, I am trying to validate a text input when it loses focus. I would like to know which row of the table it is in. This is what I have so far and it keeps coming back as undefined. Any ideas? $("div#step-2 fieldset table tbody tr td input").blur(function() { var tableRow = $(this).parent().parent(); if ($.trim($(this).val()) == "") { $(this).addClass("invalid"); alert(tableRow.rowIndex); $(this).val(""); } else { $(this).removeClass("invalid"); checkTextChanges(); } });

• jQuery autocomplete not always working on elements

  - by PoweRoy

  I'm trying to create a greasemonkey script (for Opera) to add autocomplete to input elements found on a webpage but it's not completely working. I first got the autocomplete plugin working: // ==UserScript== // @name autocomplete // @description autocomplete // @include * // ==/UserScript== // Add jQuery var GM_JQ = document.createElement('script'); GM_JQ.src = 'http://jquery.com/src/jquery-latest.js'; GM_JQ.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(GM_JQ); var GM_CSS = document.createElement('link'); GM_CSS.rel = 'stylesheet'; GM_CSS.href = 'http://dev.jquery.com/view/trunk/plugins/autocomplete/jquery.autocomplete.css'; document.getElementsByTagName('head')[0].appendChild(GM_CSS); var GM_JQ_autocomplete = document.createElement('script'); GM_JQ_autocomplete.type = 'text/javascript'; GM_JQ_autocomplete.src = 'http://dev.jquery.com/view/trunk/plugins/autocomplete/jquery.autocomplete.js'; document.getElementsByTagName('head')[0].appendChild(GM_JQ_autocomplete); // Check if jQuery's loaded function GM_wait() { if(typeof window.jQuery == 'undefined') { window.setTimeout(GM_wait,100); } else { $ = window.jQuery; letsJQuery(); } } GM_wait(); function letsJQuery() { $("input[type='text']").each(function(index) { $(this).val("test autocomplete"); }); $("input[type='text']").autocomplete("http://mysite/jquery_autocomplete.php", { dataType: 'jsonp', parse: function(data) { var rows = new Array(); for(var i=0; i<data.length; i++){ rows[i] = { data:data[i], value:data[i], result:data[i] }; } return rows; }, formatItem: function(row, position, length) { return row; }, }); } I see the 'test autocomplete' but using the Opera debugger(firefly) I don't see any communication to my php page. (yes mysite is fictional, but it works here) Trying it on my own page: <body> no autocomplete: <input type="text" name="q1" id="script_1"><br> autocomplete on: <input type="text" name="q2" id="script_2" autocomplete="on"><br> autocomplete off: <input type="text" name="q3" id="script_3" autocomplete="off"><br> autocomplete off: <input type="text" name="q4" id="script_4" autocomplete="off"><br> </body> This works, but when trying on another pages it sometimes won't: e.g. http://spitsnieuws.nl/ works but http://nu.nl and http://dumpert.nl don't work. Trying the autocomplete of jquery ui has more problems: // ==UserScript== // @name autocomplete // @description autocomplete // @include * // ==/UserScript== // Add jQuery var GM_JQ = document.createElement('script'); GM_JQ.src = 'http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js'; GM_JQ.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(GM_JQ); var GM_CSS = document.createElement('link'); GM_CSS.rel = 'stylesheet'; GM_CSS.href = 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css'; document.getElementsByTagName('head')[0].appendChild(GM_CSS); var GM_JQ_autocomplete = document.createElement('script'); GM_JQ_autocomplete.type = 'text/javascript'; GM_JQ_autocomplete.src = 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js'; document.getElementsByTagName('head')[0].appendChild(GM_JQ_autocomplete); // Check if jQuery's loaded function GM_wait() { if(typeof window.jQuery == 'undefined') { window.setTimeout(GM_wait,100); } else { $ = window.jQuery; letsJQuery(); } } GM_wait(); // All your GM code must be inside this function function letsJQuery() { $("input[type='text']").each(function(index) { $(this).val("test autocomplete"); }); $("input[type='text']").autocomplete({ source: function(request, response) { $.ajax({ url: "http://mysite/jquery_autocomplete.php", dataType: "jsonp", success: function(data) { response($.map(data, function(item) { return { label: item, value: item } })) } }) } }); } This will work on my html page, http://spitsnieuws.nl and http://dumpert.nl but not on http://nu.nl. (dumpert didn't work on the plugin autocomplete) //http://spitsnieuws.nl <input class="frmtxt ac_input" type="text" id="zktxt" name="query" autocomplete="off"> //http://dumpert.nl <input type="text" name="srchtxt" id="srchtxt"> //http://nu.nl <input id="zoekfield" name="q" type="text" value="Zoek nieuws" onfocus="this.select()" type="text"> Anyone know why the autocomplete functionality doesn't work? Why the request to the php page is not being made? And why I can't add my autocomplete to google.com?

• Parsing prototype AJAX.response XML in IE

  - by adam

  Hi I have an xml webservice which I'm fetching using PrototypeJS. The xml has the correct content type and is well-formed, and looks like this: <GetTokenResponse xmlns="http://tempuri.org/"> <GetTokenResult>F655100D64F098F0AC33AFF414A4A0D5</GetTokenResult> </GetTokenResponse> The AJAX request is completing successfully, and I can access the GetTokenResult node in both IE and FF but can only get the text content of the node in FF. My code is below: node = transport.responseXML.documentElement.getElementsByTagName('GetTokenResult')[0]; rawToken = (document.all) ? node.innerText : node.textContent; I've tried innerText and innerHTML, as well as children[0] and a few other chance guesses but IE returns 'undefined' when I access rawToken. Anyone able to lend a hand? Thanks, Adam

• Static lib that links another static lib and qmake? Odd linking error

  - by Dan O

  I have two qt .pro files, both using the lib TEMPLATE and staticlib CONFIG. The first library (lets call it 'core') is a dependency for the second lib (I'll call it 'foo'). In fact, there's a class in foo that extends a class in core, I will call this class Bar. When I instantiate the class (which is defined and implemented in foo, but extends a class (Bar) from core) in another project (not a lib) I get the following linking error: /usr/bin/ld: Undefined symbols: Bar::Bar() Basically, the linker cannot find the class in the core lib that has been derived in the foo lib, but ONLY when I instantiate the class in a third project that is using both libs. Is this behaviour expected? Regards, Dan O Update: I fixed it by directly invoking the Bars constructor in the third project before using derived class... does anyone know why I need to do this?

• Redirect input from one terminal to another

  - by Niki Yoshiuchi

  I have sshed into a linux box and I'm using dvtm and bash (although I have also tried this with Gnu screen and bash). I have two terminals, current /dev/pts/29 and /dev/pts/130. I want to redirect the input from one to the other. From what I understand, in /dev/pts/130 I can type: cat </dev/pts/29 And then when I type in /dev/pts/29 the characters I type should show up in /dev/pts/130. However what ends up happening is that every other character I type gets redirected. For example, if I type "hello" I get this: /dev/pts/29 | /dev/pts/130 $ | $ cat </dev/pts/29 $ el | hlo This is really frustrating as I need to do this in order to redirect the io of a process running in gdb (I've tried both run /dev/pts/# and set inferior-tty /dev/pts/# and both resulted in the aforementioned behavior). Am I doing something wrong, or is this a bug in bash/screen/dvtm?

• Web-based interface is mangled

  - by justSteve

  Linksys WRT54 - over the last couple days i've been in and out of network configuration screens of my DSL modem and the router (and the commandline for that matter) as I've installed the DynDNS service. (thankx to subsonic and DynDNS.com i'm now able to stream my workstations MP3 catalog over my wife's Droid - making me her tech hero all over again) Somewhere after getting all the net ducks lined up - ports forwarded and firewalls configured - the web-interface for the router ceased rendering the full page - it's only rendering parts, i can F5/refresh and it re-renders and displays some of the cells (table-based webpage) but omits others that _had rendered before the refresh. Happens for both IE and FF. And continues after a reboot. Probably need to re-cycle the router itself but is this known behavior or should i look deeper for a cause? thx

• How can I call a module in a Perl one-liner?

  - by Zaid

  Say I have a data file that I want to process; I want to take the maximum value of each of the column and append it to the end of each line. INPUT: T1 T2 T3 35.82 34.67 31.68 32.20 34.52 33.59 37.41 38.64 37.56 OUTPUT: T1 T2 T3 35.82 34.67 31.68 35.82 32.20 34.52 33.59 34.52 37.41 38.64 37.56 38.64 I'm trying to implement this as a one-liner. So far, this is what I've come up with, although it complains that &main::max is undefined: perl -MList::Util -ani.bak -e "print qq(@F).q( ).max(@F).qq(\n)" file1.txt It seems that I haven't loaded the List::Util module. What's wrong? And is the header column an issue? perlrun doesn't have a decent example on how to do this (actually it does now, my documentation was a little out-of-date).

• How to render a Partial from a Model in Rails 2.3.5

  - by empire29

  I have a Rails 2.3.5 application and Im trying to render several Partials from within a Model (i know, i know -- im not supposed to). The reason im doing this is im integrating a Comet server (APE) into my Rails app and need to push updates out based on the Model's events (ex. after_create). I have tried doing this: ActionView::Base.new(Rails::Configuration.new.view_path).render(:partial => "pages/show", :locals => {:page => self}) Which allows me to render simple partials that don't user helpers, however if I try to user a link_to in my partial, i receive an error stating: undefined method `url_for' for nil:NilClass I've made sure that the object being passed into the "project_path(project)" is not nil. I've also tried including: include ActionView::Helpers::UrlHelper include ActionController::UrlWriter in the Module that contains the method that makes the above "render" call. Does anyone know how to work around this? Thanks

• Why are there tons of PHP processes open on my server?

  - by fiftyeight

  Today I saw that a website of mine isn't working so I ssh'd to the server and executed ps -eF. I see about 200 PHP processes that are running all for 4 hours. Apache is built with mpm event and mod fcgid. I killed all the PHP processes and now it's running fine, why does this happen? is this expected behavior? I don't really understand how processes how Apache keeps track of the number of PHP processes and their process IDs, so it would be nice if someone can also give some reference when I can read about this. Also, I used the "ab" command (Apache Benchmark) to see if this happens all the time, so I ran it about 4-5 times with 30 concurrent requests and again there are like 150 PHP processes running, when I keep running "ab" now it doesn't spawn more processes and the website is still working. Please shed some light on this! Thank you :)

• VirtuaWin shows Visual Studio 2010 in all Desktops

  - by w0lf

  I'm using VirtuaWin in Windows 7 to have virtual desktop functionality and I think this program is awesome. There's one small issue, though: on the computer at work, when moving to another desktop it hides all windows in the current desktop, except any windows of Visual Studio 2010. This means that VS 2010 shows up in all desktops, while for all other windows, VirtuaWin applies the correct behavior. The strange thing is that this issue happens on one computer only; on the others I have it works OK. I have checked the Window Rules section and nothing seems strange in there. Is anyone else experiencing this kind of problem? Any ideas on how to solve it?

• Sendmail - preventing aliased users from receiving multiple copies of the same email

  - by MikeQ

  Is there any way to prevent a user from receiving multiple copies of the same email if an email is sent to both an alias for the user as well as the user themselves? For example, suppose bob.smith is a included in the alias list for developers (@company.com) If I send the email to both the user and an alias for the user: To: [email protected], [email protected] ... is there any way to prevent user Bob from receiving the same email two times? EDIT: I've observed that if Bob is a member of two different alias groups, and I send an email just to those two groups (not the user directly), sendmail correctly expands the groups and removes the duplicate. The behavior I want to fix occurs when you send directly to the user AND a group they belong to.

• CentOS connect to the internet

  - by Delirium tremens

  I installed CentOS, but it didn't automatically connect to the internet. Is that the normal behavior? I have Ethernet Broadband Router DI-604 and WebStar DPX2203 series Cablemodem with EMTA . What should I do to connect to the internet? Update: A cousin told me my ethernet adapter or network board will depend on my motherboard. My computer upgrade document says the motherboard is gigabyte video onboard. I heard gigabyte's network adapters are Gigabit or Realtek. In CentOS, System - Administration - Network - New - Ethernet, first, only "Other Network Board" was listed, so I selected it and clicked Next, then there wasn't Gigabit, but there was Realtek, so I selected Realtek. I heard with Net Virtua selecting dhcp the things first answered asked me to tell first answerer are automatically configured. So I tried Realtek with dhcp, but it still didn't work.

• Virtualmin deactivating PHP on new virtual servers

  - by Josh

  This is related to my other question... but the situation is much worse now. After updating to the most recent version of Virtualmin, when I create new accounts, Virtualmin sets up their VirtualHost entries as follows: <Directory /home/username/public_html> Options -Indexes +IncludesNOEXEC +FollowSymLinks +ExecCGI allow from all AllowOverride All AddHandler fcgid-script .php FCGIWrapper /home/username/fcgi-bin/php.fcgi .php </Directory> <Directory /home/username/cgi-bin> allow from all </Directory> [...] RemoveHandler .php Now, not only is it specifically inserting AddHandler fcgid-script and FCGIWrapper... which I do not want because I am using mod_fastcgi, but it's also setting up PHP in such a way that it will never work! It's adding a RemoveHandler .php after setting up the handler for PHP! Where is this behavior configured and how can I stop it? Better yet, how can I make Virtualmin not include any PHP commands at all in the VirtualHost section?

• Could the assign function for containers possibly overflow?

  - by Kristo

  I ran into this question today and thought I should post it for the community's reference and/or opinions. The standard C++ containers vector, deque, list, and string provide an assign member function. There are two versions; I'm primarily interested in the one accepting an iterator range. The Josuttis book is a little ambiguous with its description. From p. 237... Assigns all elements of the range [beg,end); this is, is replaces all existing elements with copies of the elements of [beg,end). It doesn't say what happens if the size of the assignee container is different from the range being assigned. Does it truncate? Does it automagically expand? Is it undefined behavior?

• Chart Control Inside SSRS ReportViewer is Viewable From Localhost But Not Internet

  - by Daniel Coffman

  A project I own was just moved from an older server to a new one, and in the process of moving the web folder, re-deploying the SSRS reports, restoring the database, configuring IIS, etc... I have lost the ability to view the Microsoft Chart Controls that are embedded in the SSRS reports, that are then displayed by a Microsoft.ReportViewer. I could view them both locally and remotely (via the internet) on the old server. I can view them if I preview the SSRS report in Visual Studio. The report displays fine, only missing all the embedded charts. I can still view them locally through the web browser, just not from the internet. What am I missing? I tried giving permissions to the ChartImageHandler temp storage folder, but it didn't work. I'm getting the Javascript error: Error: ClientReport380ec8ca0c294a809e9986c1bef9db1c is undefined

• CakePHP Accessing Dynamically Created Tables?

  - by Dave

  As part of a web application users can upload files of data, which generates a new table in a dedicated MySQL database to store the data in. They can then manipulate this data in various ways. The next version of this app is being written in CakePHP, and at the moment I can't figure out how to dynamically assign these tables at runtime. I have the different database config's set up and can create the tables on data upload just fine, but once this is completed I cannot access the new table from the controller as part of the record CRUD actions for the data manipulate. I hoped that it would be along the lines of function controllerAction(){ $this->uses[] = 'newTable'; $data = $this->newTable->find('all'); //use data } But it returns the error Undefined property: ReportsController::$newTable Fatal error: Call to a member function find() on a non-object in /app/controllers/reports_controller.php on line 60 Can anyone help.

• doctrine2: many-to-one with non default referencedColumnName does not persist entity

  - by timaschew

  I'm using symfony 2.1.2 with FOSUserBundle. I extend the User from FOS and define a many-to-one (bidirectional) association to a Customer entity. I don't want to use primary key for the association (referencedColumnName). I will use another integer uniqe column: customer_no use FOS\UserBundle\Entity\User as BaseUser; /** * @ORM\Entity * @ORM\Table(name="t_myuser") */ class MyUser extends BaseUser { /** * @ORM\ManyToOne(targetEntity="Customer", inversedBy="user") * @ORM\JoinColumn(name="customer_no", referencedColumnName="customer_no", nullable=false) */ $public $customer; } /** * @ORM\Entity * @ORM\Table(name="t_customer") */ class Customer extends BaseEntity // provides an id (pk) { /** * @ORM\Column(type="integer", unique=true, nullable=false) */ public $customer_no; /** * @ORM\OneToMany(targetEntity="MyUser", mappedBy="customer") */ public $user; } When I try to persist (via a form) a new MyUser entity with an (already in db existing and) loaded Customer entity from db, I get this error: Notice: Undefined index: customer_no in ...\vendor\doctrine\orm\lib\Doctrine\ORM\Persisters\BasicEntityPersister.php line 608 The schema on the db is all right. //update: I fix the inversedBy and mappedBy stuff, but this is not the problem.

• TFS2010 - Correctly setting up Host Header

  - by Keith Barrows

  We have a TFS2010 install on a Win2008R2 Server running IIS7. I've created a host header for TFS and want to use that instead of machineName:8080. I am getting weird behavior from it now. Every other time I log in I get: TF31002: Unable to connect to this Team Foundation Server: http://web2/tfs. Team Foundation Server Url: http://web2/tfs. Possible reasons for failure include: - The name, port number, or protocol for the Team Foundation Server is incorrect. - The Team Foundation Server is offline. - The password has expired or is incorrect. Technical information (for administrator): The request failed with HTTP status 404: Not Found. I force a reconnect and voila - there it is. Also, connecting to the web site rarely works but connecting via VS2010 works 50% of the time. What do i need to change to stabilize this?

• Global variables in jQuery

  I have been working on this script: <script type="text/javascript" src="/js/jquery.js"></script> <script type="text/javascript"> $(function(){ compentecy = $('#competency_id'); $('#add_competency').bind('click', function(e){ e.preventDefault(); $.post('/script.php', {competency_id: compentecy.val(), syllabus_id: 2}, function(){ // competency = $('#competency_id'); competency.children('option[value=' + compentecy.val() + ']').remove(); }); }); }); </script> in the $.post callback function, it seems that I can't access global variables. I tried $.competency but it didn't work. I always get a "competency is undefined" error. I had to reinitialize the variable once again inside the callback. Is there a way to NOT reinitialize the variable inside the callback?

• Typescript + requirejs: How to handle circular dependencies?

  - by Aymeric Gaurat-Apelli

  I am in the process of porting my JS+requirejs code to typescript+requirejs. One scenario I haven't found how to handle is circular dependencies. Require.js returns undefined on modules that are also dependent on the current and to solve this problem you can do: MyClass.js define(["Modules/dataModel"], function(dataModel){ return function(){ dataModel = require("Modules/dataModel"); ... } }); Now in typescript, I have: MyClass.ts import dataModel = require("Modules/dataModel"); class MyClass { dataModel: any; constructor(){ this.dataModel = require("Modules/dataModel"); // <- this kind of works but I lose typechecking ... } } How to call require a second time and yet keep the type checking benefits of typescript? dataModel is a module { ... }

• Can't access dojo object property using string variable

  - by Kareem

  I am retrieving a json associative array using a dojo xhrGet request. The data comes back just fine, however I need the app to be able to display the keys and their properties (or values) without knowing the keys beforehand. So, I do the following: function getData() { dojo.xhrGet( { url: "ytd_process.php", handleAs: "json", load: function(response) { for (var key in response) { dojo.byId("boxes").innerHTML+="<div id=\"box\">"+key+":"+response.key+"</div>"; } console.dir(response); // Dump it to the console } }); }; The keys are retrieved and displayed on the page, but the response.key returns undefined. I know the syntax is correct because if I replace .key with an actual key value it will display correctly. It appears it doesn't like a string as the key. Any help or advice would be greatly appreciated. Thank you.
