• HTML, PHP No data in drop down box

  - by Makinitez21

  Hey, I am trying to figure out why a website's drop down box will not show any options. The data file for this drop down box comes from a microsoft access .mde file. The file is present and after the last update was working fine. Some changes happened to the site, i.e. text got added along with some photos. Im not saying this was when the drop down box went bad, but when it was discovered these were the only changes made. The data file seems fine as it is worked with everyday. Can anyone point me in the right direction as to where to begin looking for the bug? For a better idea of what I am talking about, check out the Site http://yogaalliance.org/teacher_search.cfm and try selecting a country. Thank you in advance

• Doctrine SQL Server uniqueidentifier isn't cast as char or nvarchar when retrieved from the database

  - by Tres

  When I retrieve a record from the database which has a column of type "uniqueidentifier", Doctrine fills it with "null" rather than the unique id from the database. Some research and testing has brought this down to a PDO/dblib driver issue. When directly querying via PDO, null is returned in place of the unique id. For reference, http://trac.doctrine-project.org/ticket/1096, has a bit on this, however, it was updated 11 months ago with no comment for resolution. A way around this, as mentioned at http://bugs.php.net/bug.php?id=24752&edit=1, is to cast the column as a char. However, it doesn't seem Doctrine exposes the native field type outside of generating models which makes it a bit hard to detect uniqueidentifier types and cast them internally when building the sql query. Has anyone found a workaround for this?

• TFS Automated Builds to Code Packages

  - by Adam Jenkin

  I would like to hear the best practices or know how people perform the following task in TFS 2008. I am intending on using TFS for building and storing web applications projects. Sometimes these projects can contain 100's of files (*.cs, *.acsx etc) During the lifetime of the website, a small bug will get raised resulting in say a stylesheet change, and a change to default.aspx.cs for example. On checking in these changes to TFS, and automated build would be triggered (great!), however for deploying the changes to the target production machine, I only need to deploy for example: style.css default.asx MyWebApplications.dll So my question is, can MSBuild be customized to generate a "code pack" of only the files which require deploying to the production server based on the changeset which cause the re-build?

• To implement a remote desktop sharing solution

  - by Cameigons

  Hi, I'm on planning/modeling phase to develop a remote desktop sharing solution, which must be web browser based. In other words: an user will be able to see and interact with someone's remote desktop using his web-browser. Everything the user who wants to share his desktop will need, besides his browser, is installing an add-in, which he's going to be prompted about when necessary. The add-in is required since (afaik) no browser technology allows desktop control from an app running within the browser alone. The add-in installation process must be as simple and transparent as possible to the user (similar to AdobeConnectNow, in case anyone's acquainted with it). The user can share his desktop with lots of people at the same time, but concede desktop control to only one of them at a time(makes no sense being otherwise). Project requirements: All technology employed must be open-source license compatible Both front ends are going to be in flash (browser) Must work on Linux, Windows XP(and later) and MacOSX. Must work at least with IE7(and later) and Firefox3.0(and later). At the very least, once the sharer's stream hits the server from where it'll be broadcast, hereon it must be broadcasted in flv (so I'm thinking whether to do the encoding at the client's machine (the one sharing the desktop) or send it in some other format to the server and encode it there). Performance and scalability are important: It must be able to handle hundreds of dozens of users(one desktop sharer, the rest viewers) We'll definitely be using red5. My doubts concern mostly implementing the desktop publisher side (add-in and streamer): 1) Are you aware of other projects that I could look into for ideas? (I'm aware of bigbluebutton.org and code.google.com/p/openmeetings) 2) Should I base myself on VNC ? 3) Bearing in mind the need to have it working cross-platform, what language should I go with? (My team is very used with java and I have some knowledge of C/C++, but anything goes really). 4) Any other advices are appreciated.

• Code Igniter Update Engine

  - by tarnfeld

  Hey, I am planning to develop a pretty awesome new web app that has a one time fee including free updates of 1.X updates (X being the update). I don't want to get people to download a new version and install it manually as it can be a real pain for some people, also it's bad if there is an important bug that needs fixing and people don't update. The app will be built with Code Igniter so I was looking for some kind of integrated system that allowed me to send out updates for the web app? All suggestions are very much appreciated!

• Rails 3 ActiveModel Nested Class I18n

  - by Dave

  Given the following class definition in ruby: class Conversation class Message include ActiveModel::Validations attr_accessor :quantity validates :quantity, :presence => true end end How can you use i18n to customize to error message. For example the correct lookup for the class Conversation would be activemodel: errors: models: conversation: attributes: quantity: blank: "Some custom message" But what is it for the Message class? I tried: activemodel: errors: models: conversation: message: attributes: quantity: blank: "Some custom message" activemodel: errors: models: message: attributes: quantity: blank: "Some custom message" activemodel: errors: models: conversation::message: attributes: quantity: blank: "Some custom message" None of them work Any ideas or is this a bug with ActiveModel or I18n?

• What do you call the highlight as you hover over an OPTION in a SELECT, and how can I "un"highlight

  - by devils-avacado

  I'm working on dropdowns in IE6 (SELECT with OPTIONs as children). I'm experiencing the problem where, in IE6, dropdown menus are truncated to the width of the SELECT element. I used this jquery to fix it: var css_expanded = { 'width' : 'auto', 'position' : 'absolute', 'left' : '564px', 'top' : '393px' } var css_off = { 'width' : '190px', 'position' : 'relative', 'left' : '0', 'top' : '0' } if($.browser.msie) { $('#dropdown') .bind('mouseover', function() { $(this).css(css_expanded); }) .bind('click', function() { $(this).toggleClass('clicked'); }) .bind('mouseout', function() { if (!$(this).hasClass('clicked')) { $(this).css(css_off); } }) .bind('change blur focusout', function() { $(this).removeClass('clicked') .css(css_off) }); }; It works fine in IE7+8, but in IE6, if the user clicks on a SELECT and does not click any OPTION but instead clicks somewhere else on the page, outside the SELECT (blur), the SELECT still has a "highlight", the same as if they were hovering over an OPTION with my mouse (in my case, a blue color), and the width is not restored until the user clicks outside the SELECT a second time. In other browsers, blur causes every OPTION to not be highlighted. Using JS, how can I de-highlight an option after the dropdown has lost focus.

• C#.NET : A graphical control makes my app freeze after workstation unlock

  - by leo

  Hi, I have a graphical control that is multithreaded. Until now it worked fine, but I just noticed that whenever I'm on my application showing this control the following happens: if I lock and unlock my workstation, it freezes, like if it were in some kind of infinite loop. Even stranger, this bug occurs only when I'm not lauching the app from Visual Studio, and not attached to it. Does anyone have a clue on what's happening? For instance, if I attach Visual Studio to the already freezed app, can I see which lines of code my threads are executing ? Any help will be appreciated!

• Why does this regular expression for sed break inside Makefile?

  - by jcrocholl

  I'm using GNU Make 3.81, and I have the following rule in my Makefile: jslint : java org.mozilla.javascript.tools.shell.Main jslint.js mango.js \ | sed 's/Lint at line \([0-9]\+\) character \([0-9]\+\)/mango.js:\1:\2/' This works fine if I enter it directly on the command line, but the regular expression does not match if I run it with "make jslint". However, it works if I replace \+ with \{1,\} in the Makefile: jslint : java org.mozilla.javascript.tools.shell.Main jslint.js mango.js \ | sed 's/Lint at line \([0-9]\{1,\}\) character \([0-9]\{1,\}\)/mango.js:\1:\2/' Is there some special meaning to \+ in Makefiles, or is this a bug?

• Ray intersection and child camera

  - by lutangar

  I've been playing with three.js for few weeks now and got few inconsistencies on ray casting. Here is a simplified version demonstrating one of the bug I encoutered : http://jsfiddle.net/eMrhb/12/ The camera is added to the sphere mesh for further use of TrackBallControl for example. scene.add(mesh); mesh.add(camera); Clicking a few times on the sphere and opening the console, show us none of the expected intersections between the ray and the mesh. Adding the camera to the scene (http://jsfiddle.net/eMrhb/9/), solves the problem: scene.add(mesh); scene.add(camera); But I could use a much more complex hierarchy between my scene objects and the camera to suit my needs. Is this a limitation? If it is, is there any workarounds I could use?

• Memory leak till crash due to HttpRequest

  - by Alex R.

  I played with HttpRequest and realized that the memory is not cleaned up after any request. After some time the running tab within Chrome will crash. Here is some testing code. Put a large sized file into the 'www' directory and set the URL in the code accordingly. import 'dart:async'; import 'dart:html'; void main() { const PATH = "http://127.0.0.1:3030/PATH_TO_FILE"; new Timer.periodic(new Duration(seconds:10), (Timer it)=>getString(PATH)); } void getString( String url){ HttpRequest.getString(url).then((String data){ }); } Is this really a bug or did I something wrong?

• Why doesn't MySQL support millisecond / microsecond precision?

  - by Byron Whitlock

  So I just found the most frustrating bug ever in MySQL. Apparently the TIMESTAMP field, and supporting functions do not support any greater precision than seconds!? So I am using PHP and Doctrine, and I really need those microseconds (I am using the actAs: [Timestampable] property). I found a that I can use a BIGINT field to store the values. But will doctrine add the milliseconds? I think it just assigns NOW() to the field. I am also worried the date manipulation functions (in SQL) sprinkled through the code will break. I also saw something about compiling a UDF extension. This is not an acceptable because I or a future maintainer will upgrade and poof, change gone. Has anyone found a suitable workaround?

• XamlXmlReader.Read() does not yield matching XamlNodeType.StartObject and XamlNodeType.EndObject on

  - by Yuval

  Hi, I am trying to parse a valid xaml file using the XamlXmlReader. It looks like it is 'skipping' some elements when when Read() is called. for example on the following xaml snippet: <UserControl.Resources> <Converters:AnyDbTypeToDisplayNameConverter x:Key="anyDbTypeToDisplayNameConverter" /> </UserControl.Resources> when reading I first get a XamlNodeType.StartObject on UserControl.Resources - makes sense then another XamlNodeType.StartObject on Converters - also cool. but then i do not get a XamlNodeType.EndObject on the Converters and immediately jump to the next line and does not report a XamlNodeType.StartObject. Any Idea if this is working as design ? looks like a bug to me

• Select calls seems to not time out.

  - by martsbradley

  HI Folks, I have a threaded C++ program where up to three threads are calling select on a three separate socket descriptors waiting for data to become available. Each thread handles one socket and adds it to the readfds with a timeout of 300 seconds. After select returns if there is data available I'm calling recv to read it. Is there anything that I need to be aware of with winsock and threads because for some reason after a number of hours the select calls all seem to be not timing out. Can a multi threaded program select from a number of threads without issue? I know that I should have one thread listening to all three sockets however that would be a large change for this app and I'm only looking to apply a bug fix. cheers, Martin.

• On Solaris, what is the difference between cut and gcut?

  - by Chris J

  I recently came across this crazy script bug on one of my Solaris machines. I found that cut on Solaris skips lines from the files that it processes (or at least very large ones - 800 MB in my case). > cut -f 1 test.tsv | wc -l 457030 > gcut -f 1 test.tsv | wc -l 840571 > cut -f 1 test.tsv > temp_cut_1.txt > gcut -f 1 test.tsv > temp_gcut_1.txt > diff temp_cut_1.txt temp_gcut_1.txt | grep '[<]' | wc -l 0 My question is what the hell is going on with Solaris cut? My solution is updating my scripts to use gcut but... what the hell?

• What is the purpose of the Html "no-js" class?

  - by Swader

  I notice that in a lot of template engines, in the HTML5 Boilerplate, in various frameworks and in plain php sites there is the no-js class added onto the html element. Why is this done? Is there some sort of default browser behavior that reacts to this class? Why include it always? Does that not render the class itself obsolete, if there is no no-"no-js" case and html can be addressed directly? Here is an example from the HTML5 Boilerplate index.html: <!--[if lt IE 7 ]> <html lang="en" class="no-js ie6"> <![endif]--> <!--[if IE 7 ]> <html lang="en" class="no-js ie7"> <![endif]--> <!--[if IE 8 ]> <html lang="en" class="no-js ie8"> <![endif]--> <!--[if IE 9 ]> <html lang="en" class="no-js ie9"> <![endif]--> <!--[if (gt IE 9)|!(IE)]><!--> <html lang="en" class="no-js"> <!--<![endif]--> As you can see, the html element will always have this class. Can someone explain why this is done so often?

• Why is this std::bind not converted to std::function?

  - by dauphic

  Why is the nested std::bind in the below code not implicitly converted to an std::function<void()> by any of the major compilers (VS2010/2012, gcc, clang)? Is this standard behavior, or a bug? #include <functional> void bar(int, std::function<void()>) { } void foo() { } int main() { std::function<void(int, std::function<void()>)> func; func = std::bind(bar, 5, std::bind(foo)); std::cin.get(); return 0; }

• ASP.NET 2.0 + Firefox/Safari - UI Issues?

  - by Tejaswi Yerukalapudi

  I'm developing on a system that was originally developed five years ago. I don't have access to the complete source code of the system, but it is completely driven by XML and runs on ASP.NET 2.0. This was originally written for IE6, but since Microsoft has officially decided to dump it, we moved to IE7. Some javascript is added on the client side, but nothing that changes the UI has been done. (We had to integrate a credit card reader into the system) This code is accessed primarily on tablet PCs running windows, but I'd like to persuade my company to use the iPad. [The tablet somehow costs around 3k$. I think selling a 3000$ device to a client when you have the iPad for 500$ is ridiculous.] Now, my problem is if we open it in any other browser (Tested it on safari / firefox), the UI is completely messed up with elements completely out of place. Doesn't ASP.NET generate HTML that runs on any browser? My second question is if there are any credit card readers available in the market that integrate with the iPad. I don't really care about the software part as it's taken care by our company, I just need it to read the card details and post it to the server. Thanks, Teja.

• Incorrect error

  - by jspooner

  If you assign an invalid date (like December 39th) to a datetime column ActiveRecord returns a "can't be blank" error when is should probably return an error like "Not a valid date" My question. Is this expected rails behavior, a bug or, something that I could patch? class ExerciseLog < ActiveRecord::Base validates_presence_of :scheduled_datetime end Fire up the console. e = Log.new # lets set a date for Dec 39th which obviously doesn't exist e.scheduled_datetime = "2010-12-39" e.save => false # this is the confusing message since our form did post a valid date e.errors.on(:scheduled_datetime) => "can't be blank" e.scheduled_datetime = "2010-12-30" e.save => true I discovered this issue when I accidentally transposed the month and day values. btw This is in Rails 2.3.5

• How to break whenever any line of code executes

  - by Aequitarum Custos

  I have a very strange bug, which I believe is caused by some code we have executing, but I'm not sure where. We can reproduce it to the point it happens whenever we click Tab, but short of putting a break point at the beginning of every method in the project to find out what is executing. Is there a way to set visual studio to break whenever anything executes? For those curious about the problem, every now and then, we have a few Rich Text Boxes that refuse to lose focus. You can't click out of it or tab out of it. We have no On Validation or On Text Changed events attached to the control, and believe it's an event attached somewhere else to something we just aren't noticing.

• write.table in R screws up header when has rownames

  - by Yannick Wurm

  Hello, check this example: > a = matrix(1:9, nrow = 3, ncol = 3, dimnames = list(LETTERS[1:3], LETTERS[1:3])) > a A B C A 1 4 7 B 2 5 8 C 3 6 9 the table displays correctly. There are two different ways of writing it to file... write.csv(a, 'a.csv') which gives as expected: "","A","B","C" "A",1,4,7 "B",2,5,8 "C",3,6,9 and write.table(a, 'a.txt') which screws up "A" "B" "C" "A" 1 4 7 "B" 2 5 8 "C" 3 6 9 indeed, an empty tab is missing.... which is a pain in the butt for downstream things. Is this a bug or a feature? Is there a workaround? (other than write.table(cbind(rownames(a), a), 'a.txt', row.names=FALSE) Cheers, yannick

• qapps runs well but breakpoint sometimes generates segmentation fault

  - by yan bellavance

  I have a qApp that generates a segmentation fault only when a breakpoint is inserted in the code (I can put it at different places) and only after 4-5 breakpoint stops. Do I have a problem with my code or is this a DBG bug. the method is part of a QThread Class. Basically what I did is i took the mandlebrot example, and have 3 instances of it in my program. So the program would look like a mainwindow that has 3 mandlebrot widgets in it, one besides the other. Is it possible that GDB doesnt support debugging qthread subclasses that are instantiated multiple times or is it thread-unsafe to do so. I dont have any problems at run-time.

• PreparedStatement and setTimestamp in oracle jdbc

  - by Roman

  Hi everyone, I am using PreparedStatement with Timestamp in where clause: PreparedStatement s=c.prepareStatement("select utctimestamp from t where utctimestamp>=? and utctimestamp<?"); s.setTimestamp(1, new Timestamp(1273017600000L)); //2010-05-05 00:00 GMT s.setTimestamp(2, new Timestamp(1273104000000L)); //2010-05-06 00:00 GMT The result I get is different, when I have different time zones on the client computer. Is this a bug in Oracle jdbc? or correct behavior? The parameter is Timestamp, and I expected that no time conversions will be done on the way. The database column type is DATE, but I also checked it with TIMESTAMP column type with the same results. Is there a way to achieve correct result? I cannot change default timezone in the the whole application to UTC. Thanks for your help

• Saving a movie generated with Jython/JES on local disk

  - by Golgauth

  I made an autogenerated movie clip using JES (Jython Environment for Students). I can play it without any problem using playMovie(), but I can't figure out how to have it saved physically on disk. The full script is located here. ... movie = synthesizeFrameAndCreateMovie("D:\\FOLDER") print movie writeQuicktime(movie,"D:\\FOLDER\\movie.mov", 30) [LINE 35] #playMovie(movie) I get this error when calling the function writeQuicktime(): >>> ======= Loading Progam ======= Movie, frames: 60 The error was: Index: 0, Size: 0 I wasn't able to do what you wanted. The error java.lang.IndexOutOfBoundsException has occured Please check line 35 Note : I also tried the function writeAVI(), with the exact same result. This error sounds like a java bug in Jython/JES library. I am running JES under Windows 7 and have all the common Quicktime and AVI codex installed as well as the QTjava library in my jre... Any brilliant idea ? EDIT : Also tried the Linux version with same result for both QuickTime and AVI...
