• What's wrong with this SQL UPDATE query?

  - by Tommo

  I wouldn't ask if i wasn't sure that i have 100% no idea why this isn't working, so, in PHP i'm simply trying to update a value in the MySQL database: The field im updating - Name: read - Type: tinyint - Length: 1 Here is the PHP code: do_SQL("UPDATE messages SET read=1 WHERE id='".$id."'"); The do_SQL function is working for everything else, so it's something wrong with this statement. I have tried putting 1 in '1' and it still didn't work.m The error is: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'read=1 WHERE id='1'' at line 1 Thanks for reading!

• Is there a production ready web application framework in Python?

  - by peperg

  I heard lots of good opinions about Python language. They say it's mature, expressive etc... Are there any production-ready web application frameworks in Python. By "production ready" I mean : supports objective-relational mapping with caching and declarative desciption (like JPA, Hibernate etc..) controls oriented user interface support - no HTML templates but something like JSF (RichFaces, Icefaces) or GWT, Vaadin, ZK component decomposition and dependency injection (like EJB or Spring) unit and integration testing good IDE support clustering, modularity etc (like Terracota, OSGi etc..) there are successful applications written in it by companies like IBM, Oracle etc (I mean real business applications not Twitter) could have commercial support Is it possible at all in Python world ? Or only choices are : use Python and write everything from the bottom (too expensice) stick to JEE buy .NET stack

• C# app fails to load Matlab DLL when running from a shared drive?

  - by jg

  I have a C# .NET 2.0 program that calls a Matlab .dll file that I created using Matlab Builder for .NET. This Matlab .dll file is a wrapper for a m file function that I need to call from my C# program. Everything works fine when I run this app from my local drive. However once I copy the app to a shared drive the Matlab dll fails when it's first loaded. I setup caspol to allow .NET programs to run from shared drives. Does anyone know what could cause this problem or a tool that I could use to easily figure out what the problem is? Thanks.

• MeioUpload and phpThumb() does not exist error

  - by Cameeob2003

  I am currently using CakePHP v2.2.1 and MeioUpload 4.0 along with phpThumb() to try and generate image uploads and thumbnails for those images. If i set my $actAs = array() without the thumbsizes property everything is uploaded well, but when I add the following: 'thumbsizes' => array( 'small' => array('width' => 165, 'height' => 115), 'medium' => array('width' => 800, 'height' => 600) ), to generate thumbnails I get an error stating the following: "E:/xampp/htdocs/site/vendors/phpthumb/img/posts/image-name.jpg" does not exist I have tried several different methods of fixing this from around the web and nothing seems to work. I am new to cakephp so this may be an easy fix and I am just not connecting the dots to find the solution. Any help would be very much appreciated.

• GD! Converting a png image to jpeg and making the alpha by default white and not black.

  - by Shawn

  I tried something like this but it just makes the background of the image white, not necessarily the alpha of the image. I wanted to just upload everything as jpg's so if i could somehow "flatten" a png image with some transparently to default it to just be white so i can use it as a jpg instead. Appreciate any help. Thanks. $old = imagecreatefrompng($upload); $background = imagecolorallocate($old,255,255,255); imagefill($old, 0, 0, $background); imagealphablending($old, false); imagesavealpha($old, true);

• How can you toggle between two sets of values per data series in flot?

  - by Jedidja

  flot has built-in support for multiple data series (sample code) and also dual-axis (sample code). Assuming multiple data series (water, electricity, etc) that each have an amount (usage) and a dollar value (charge for that usage), what would the best way be to to use flot to display either the amount or dollar values for all the data series, while still supporting toggling display for each individual series? The idea is to send down all the data in one GET request and then let the client take care of everything else in Javascript. Ideally we could use triplets somehow {date, amount, charge}, and then possibly split that into two arrays for flot.

• Connect to an elevated COM server from a non-elevated process

  - by JS Bangs

  We have a program which launches a child process that hosts a local COM server, which for various reasons must be launched elevated. Everything works fine so long as both the parent and the child process are elevated. However, we also want to run when the parent process is non-elevated. Launching the child process results in a UAC dialog (which is acceptable), and the child appears to start correctly and successfully calls CoRegisterClassObject. However, the parent process gets REGDB_E_CLASSNOTREG when calling CoCreateInstance with the same CLSID. I assume this is some sort of permissions issue. How can I register my class in the elevated server to allow it to be called from a non-elevated process.

• How can I accept a hash mark in a URL via $_GET?

  - by bccarlso

  From what I have been able to understand, hash marks (#) aren't sent to the server, so it doesn't seem likely that I will be able to use raw PHP to parse data like in the URL below: index.php?name=Ben&address=101 S 10th St Suite #301 I'm looking to pre-populate form fields with this $_GET data. How would I do this with Javascript (or jQuery), and is there a fallback that wouldn't break my form for people not using Javascript? Currently if there is a hash (usually in the address field), everything after that is not parsed in or stored in $_GET.

• Git fatal: remote end hung up

  So I thought I had finally got everything setup on Windows ... then ran into this issue.

Anyone suggest anything?

• How can I make rake assets:precompile build to the right location?

  - by Micah Gideon Modell

  I'm deploying my Rails 3 app to a subdirectory of my hosting service and therefore I'm using both a scope statement in my routes.rb and a config.assets.prefix. However, this causes my rake assets:precompile to build into public//assets instead of just into assets (since my prefix simply accounts for the scope). I can copy the files to the right location and everything will work, but I'd love for someone to tell me a better way (one must exist, right?). /config/application.rb config.assets.prefix = "/sapa/assets" /config/routes.rb scope "sapa" do … end Any help would be appreciated.

• How to handle multiple delegates

  - by mac_55

  I've got a view in my app that does pretty much everything, and I like it that way. The problem however is that it's implementing 5 or 6 different delegates, which seems a little bit messy. My question is, does the view controller have to implement all of the delegates? or is there some way I can separate the code out into different files (without having to do a major restructure or rewrite)? Here's all the delegates I'm implementing: @interface MyView : UIViewController <UIScrollViewDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIActionSheetDelegate, MFMailComposeViewControllerDelegate>

• Strange padding in Safari when using SVG images

  - by Naman Goel

  I thought I was having issues with margins but then on a closer look I found that SVGs are acting funky in Safari 6. I am building a simple Hexagon based website. Of course I used negative vertical margins to for a little overlap to 'inter-lock' the hexagons. And to save space I was using SVG images for the hexagons. It works great in chrome and firefox, but in Safari, there is a strange padding in the SVG images. I'm using simple img tags for the svg images. Everything works when I switch to PNG, but I'd prefer to stick to SVGs. Any insight? Can I perhaps delve into the SVG code and somehow fix the SVG problem in Safari? or is it some sort of bug, that I can do nothing about without browser sniffing?

• Can an Aspect conditionally render parts of a JSP page ?

  - by Scott The Scot

  At present the jsp pages have normal authorize tags to conditionally render links and information etc. The website is on the intranet, and we're using Spring Security 2.0.4. Ive now got a business user who wants to allow all roles to access everything for the first few weeks, then gradually add the security back in as feedback is gathered from the business. Rather than go through every page, removing the authorize tags, only to have to put them back in, is is possible to configure these through an aspect, or is there any other way to externalize this into a config file ? I've found Spring's MethodSecurityInterceptor and the meta data tags, but these wouldn't give me the externalization. I've been on google for the last hour, and am now pretty sure this can't be done, but would love to find out I haven't been asking the right questions. Advice appreciated

• Using Rails 3 and Haml 3, how do I configure Haml?

  - by dpogg1

  I'm using Rails 3.0.0.beta3 and Haml 3.0.0.rc.2, and I can't find where I need to place the configuration lines for Haml (nor what they are in the new version, for that matter). Using Rails 2.3.5 and Haml 2, I would do Haml::Template.options[:format] = :html5 in environment.rb. Or, in Sinatra, set :haml, {:format => :html5} in my main file. But in Rails 3 everything's been changed around, and no matter where I put that configuration line, I get an undefined method or undefined object error.

• GCC, functions, and pointer arguments, warning behaviour

  - by James Morris

  I've recently updated to a testing distribution, which is now using GCC 4.4.3. Now I've set everything up, I've returned to coding and have built my project and I get one of these horrible messages: *** glibc detected *** ./boxyseq: free(): invalid pointer: 0x0000000001d873e8 *** I absolutely know what is wrong here, but was rather confused as to when I saw my C code where I call a function which frees a dynamically allocated data structure - I had passed it an incompatible pointer type - a pointer to a completely different data structure. warning: passing argument 1 of 'data_A_free' from incompatible pointer type note: expected 'struct data_A *' but argument is of type 'struct data_B *' I'm confused because I'm sure this would have been an error before and compilation would never have completed. Is this not just going to make life more difficult for C programmers? Can I change it back to an error without making a whole bunch of other warnings errors too? Or am I loosing the plot and it's always been a warning?

• How to change the value of None in Python?

  - by michael

  I'm currently reading chapter 5.8 of Dive Into Python and Mark Pilgrim says: There are no constants in Python. Everything can be changed if you try hard enough. This fits with one of the core principles of Python: bad behavior should be discouraged but not banned. If you really want to change the value of None, you can do it, but don't come running to me when your code is impossible to debug. I tried this in the interpreter None = "bad" I get a SyntaxError: assignment to None Just out of curiosity how do you change None?

• Extract a C/C++ header file from a C# class exposed to COM

  - by isorfir

  I'm not sure I've setup everything I've needed to in my C# class to properly, but it does work in COM. I've been looking for an example of a C# class that was successfully used in a C/C++ project, but haven't come across anything. I've tried using the OLE/COM Object View app to open the .tlb file and save as .h, but it gives some errors: MIDL1009: unknown argument ignored; MIDL1001: cannot open input file Studio "Studio" isn't the name of the file, it's Syslog, so that raises a red flag to me. Any ideas?

• What was the most surprising failure of your 'Engineer's intuition'?

  - by Bubba88

  Hi! This may seem as an open-ended question but I'll surely accept the most impressive and upvoted answer ;) Basically, I could describe my own case - I just fail 5 times a day with my intuition cause very frequently I can be just not up-to-the-speed with my requirements/manager/team/etc. and I just have to make code quickly - that's why proper formalization in many cases stands aside. I want to gather some experience of yours - what was the most epic failure when you did rely on you implicit reasoning/intuitive knowledge/immediate perception etc. of course everything you describe should be related to programming/computers. It's mostly just to measure the danger of using that 'it's obvious..' words. I've made it com. wiki to be properly transformed after gathering enough views count. Thank you!

• AS2 acts randomly when changing scenes on the first frame

  - by fabieno

  I have a flash movie containing to scenes: scene1, scene2. I have chosen the order so that scene1 starts first, I was requested to add a functionality to allow flashvars to be passed, if fv_change equals one then scene2 should be the first to appear when the movie is loaded. I have included the following code in scene1 first frame of some layer: this.onEnterFrame = function() { delete this.onEnterFrame; if (isset==undefined && _root.fv_change && _root.fv_change==1) { isset = true; gotoAndStop("scene2",1); } } when testing in my flash environment everything worked fine, when I exported it to an HTML & SWF combo I got random results, I refreshed the page several times and some of the times scene2 appeared and some of the times it stayed with scene1. Am I doing something wrong? what is the correct way to change scene order using AS2 and external data(flashvars for that matter).

• SQL ConnectionString in web.config and global.asax implications

  - by rlb.usa

  This is going to sound very odd, but I have a web.config like this: <connectionStrings> <remove name="LocalSqlServer"/> <add name="LocalSqlServer" connectionString="Data Source=BACKUPDB;..." providerName="System.Data.SqlClient"/> </connectionStrings> And a global.asax like this: void Session_Start(object sender, EventArgs e) { // Code that runs when a new session is started if (Application["con"] == null || Application["con"] == "") { Application["con"] = "Data Source=PRODUCTIONDB;..."; } } And EVERYWHERE in my code, I reference my ConnectionStrings like this: SqlConnection con = new SqlConnection(Convert.ToString(HttpContext.Current.Application["con"])); However, I see that everything I do inside this application goes to BACKUP db instead of PRODUCTIONDB. What is going on, how could this happen, and why? It doesn't make any sense to me, and it got me into a lot of trouble. We use LocalSqlServer string for FormsAuthentication.

• How to do regex HTML tag replace in MS SQL?

  - by timmerk

  I have a table in SQL Server 2005 with hundreds of rows with HTML content. Some of the content has HTML like: <span class=heading-2>Directions</span> where "Directions" changes depending on page name. I need to change all the <span class=heading-2> and </span> tags to <h2> and </h2> tags. I wrote this query to do content changes in the past, but it doesn't work for my current problem because of the ending HTML tag: Update ContentManager Set ContentManager.Content = replace(Cast(ContentManager.Content AS NVARCHAR(Max)), 'old text', 'new text') Does anyone know how I could accomplish the span to h2 replacing purely in T-SQL? Everything I found showed I would have to do CLR integration. Thanks!

• Rails 3 nested forms with has_many :through, entry in join table dosen't get deleted after update

  - by Hadi S.

  Hi, i have a 'User' model which has a has_many relationship to a 'Number' model through a join table 'user_number' model. I use accepts_nested_attributes_for :numbers, :allow_destroy = true in the 'User' model. Everything works fine except that whenever i delete a number from a user in the edit form, the associated number is deleted correctly in the 'number' table, but not the entry in the 'user_number' join table. In the update controller action i only use this: ... if @user.update_attributes(params[:user]) ... How can i force rails to also delete the associated entry in the join table?

• Placing Select Folders Under Version Control

  - by Jonah

  Hi, I have an SVN repository on my hosted server (linux), and I need to do local work on them on my windows machine (tortoise svn installed). To simplify my question, the dir structure looks like: root |--------sub1 |--------sub2 |--------sub3 ... |--------subN with additional subfolders under each subX. Say I only want certain sub-subfolders of "sub1" and "sub3" under version control. But on windows, when I commit a change with tortoisesvn, I still want to be able to right click the root folder, hit commit, and have any changes that exist anywhere under root in any selected folders to be committed. The problem is, I think using ignore would be very cumbersome, since there would be so many folders to ignore, at different levels of structure. So basically, I want to put the whole thing under version control, and then tell svn "ok, now ignore everything except X and Y". What is the easiest way to accomplish this? Thanks, Jonah

• How can I allow anonymous access to OTRS FAQ area?

  - by robbie

  I have been searching for this for quite some time now. I am using OTRS 2.4.7 and installed the FAQ package version 1.6.5. Everything seems to work fine. When I am logged in, I can create articles and other users have the ability to browse the articles. I want to be able to allow access to any anonymous non-user to be able to read these articles. Can anyone shed some light on how to allow this type of access? Thanks
