  • Binded click loses context of my Class. JS

    - by Fabiano PS
    Hi, I have this problem that I probably understand but don't know how to handle, if there is a way. I have a class simplified as this: function DrawingTable(canvas_id){ this.canvas_id = canvas_id; bind_events() function bind_events(){ $(get_canvas()).click(function(e){ var canvas = get_canvas() //works do_something_in_the_instance_who_called_click() } function get_canvas(){return document.getElementById(canvas_id)} function do_something_in_the_instance_who_called_click(){ alert(this.canvas_id) //fail! } } Because when the click() is invoked for what it looks this is not inside the instance anymore, but I need to change atributes from there.. is there a way, given that may be multiple instances? I don't really know how but the get_canvas() works :) I'm using jQuery but likely not relevant

  • Creating a virtual, data-driven section of a Wordpress-powered site

    - by lgomez
    Hello all, I want to create a plugin for wordpress to automatically serve pages containing data pulled from a provider's API. The API returns one or more records containing data for that record and I simply want to have the plugin intercept the request, call the API with parameters pulled from the request URI and display the data using a template that I can either let them upload to the server or let them copy and paste into the plugins admin settings. For example, I may want one of my wordpress installations to show products pulled from such an API under the url "example.com/products". The plugin would catch that request, extract the variables from the URL, call the API and render the template with the returned results. I'd like to avoid requiring editing the .htaccess file like some caching plugins do. Some of the admins of these pages won't know how to do that or simply won't have access to the .htaccess file. Thanks!

  • Stop native web app from reloading itself upon opening on iOS

    - by cguedel
    I'm trying to build a "native web app" using HTML + JS on iOS. As you may know you can add such an application to the homescreen and it will more or less look just like a normal native app. However if I quit such an app and reopen it again it reloads the whole page again. This also happens when switching to such an application from another over the multitasking bar. Is this expected behaviour or is there a way to stop the device from doing this? As an example you can add the jqTouch-Demos from here to your homescreen and test it: http://jqtouch.com/preview/demos/main/

  • Should GSON ignore varying types if they're not used in a class?

    - by loeschg
    I'm making an API call that returns JSON which has a particular field which either returns false or a map depending on content. It's a field that I don't care about. I expected GSON to ignore this particular field, though it doesn't seem to be. The object generation fails with the following message: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 403560 I've seen this particular question (Gson deserialize json with varying value types). I want to make sure I need to make a custom deserializer before doing so. I'm wondering if I may have another issue. edit: Example: "anonymous_flag": { } vs "anonymous_flag": "yes" Another Edit: I actually had the field in my model object... I was referencing the wrong class. Judge away :)

  • Database permissions and ORMs

    - by Jonn
    I've been using .NET's Entity Framework a lot lately and have absolutely no wish to go back to using Stored Procedures. Been shocked though that the company I'm building this project for had a policy where applications were only given accounts that only had permissions to access stored procedures! Apparently, they believe that there's a security risk involved in allowing applications to access the tables/views directly. I don't get this. My first question is, can someone enlighten me as to what kind of security risk applications having direct access to the database may pose? AND If that's the case, are there any other ORM solutions that can provide a workaround to this (I can't think of any logical possibility atm) that would allow me to circumvent the restrictions on the user account to be assigned to me? OR is my understanding that I'd need direct permissions for the tables and views wrong?

  • Config file format

    - by Felics
    Hello, does anyone knows a file format for configuration files easy to read by humans? I want to have something like tag = value where value may be: String Number(int or float) Boolean(true/false) Array(of String values, Number values, Boolean values) Another structure(it will be more clear what I mean in the fallowing example) Now I use something like this: IntTag=1 FloatTag=1.1 StringTag="a string" BoolTag=true ArrayTag1=[1 2 3] ArrayTag2=[1.1 2.1 3.1] ArrayTag3=["str1" "str2" "str3"] StructTag= { NestedTag1=1 NestedTag2="str1" } and so on. Parsing is easy but for large files I find it hard to read/edit in text editors. I don't like xml for the same reason, it's hard to read. INI does not support nesting and I want to be able to nest tags. I also don't want a complicated format because I will use limited kind of values as I mentioned above. Thanks for any help.

  • C#+Mysql Runs out of Connections. I am using 'using' and closing all connections immediately.

    - by Cyril Gupta
    In the application that I am making right now, I am getting this error: error connecting: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. Evidently I am touching max-count in the connection pool. I am dutifully using 'using' with all connection objects and freeing them up immediately when the function is done with them. This is on C#, and I am using the MySql Data Dll. Is there something wrong with the dotnet connector for MySql? Is there a workaround?

  • Unity setting problem when defined in code

    - by Xabatcha
    I have problem when asking for default ILogger from Unity container. I have this setting defined in code (its VB.net) Dim container As IUnityContainer ... container.RegisterType(Of ILogger, NullLogger)() container.RegisterType(Of ILogger, EntLibLogger)("EL") When I am getting ILogger from container I may have different name, like: Ioc.Resolve(Of ILogger)("MyLogger") However this raises error as the mapping is not set for 'MyLogger'. Can I force container to return type which was registered without name? Actually when I used setting from web.config it worked. Any tips most welcome. Thanks. Cheers, X.

  • MySQL, return only rows where there are duplicates among two columns.

    - by Richard Waite
    I have a table in MySQL of contact information ; first name, last name, address, etc. I would like to run a query on this table that will return only rows with first and last name combinations which appear in the table more than once. I do not want to group the "duplicates" (which may only be duplicates of the first and last name, but not other information like address or birthdate) - I want to return all the "duplicate" rows so I can look over the results and determine if they are dupes or not. This seemed like it would be a simple thing to do, but it has not been. Every solution I can find either groups the dupes and gives me a count only (which is not useful for what I need to do with the results) or doesn't work at all. Is this kind of logic even possible in a query ? Should I try and do this in Python or something?

  • Is there a size limitation for an Access DB destination in SSIS?

    - by Adam V
    I'm creating an SSIS package, which will read through a user's SQL database and populate the tables in an Access database. However, for the largest user databases, I start getting errors around the time the Access file reaches approx. 2 GB. Has anyone run into this problem? Is this a size limitation for this operation?

  • vb.net : is it possible to connect to sql server 2008 via odbc but not through vb.net code?

    - by phill
    I'm supporting an old vb.net program whose database it connected to was moved from SQL Server 2005 to SQL Server 2008. Is there a setting on SQL Server 2008 which will allow ODBC connections to access the database but not allow VB.NET to connect to it programmatically? the error i keep receiving in the app is: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) however I can connect to it when I create a system dsn to the sql server instance and through VS2005's Tools Connect to Database. Here is the code I'm using to connect: dim strC as string strC = "data source=bob; database=subscribers; user id=bobuser; password=passme" dim connection as New SqlClient.SqlConnection(strC) try connection.open() catch ex as Exception msgbox(ex.message) end try connection.Close()

  • Concatenate text files with Windows command line, dropping leading lines

    - by James
    I need to concatenate some relatively large text files, and would prefer to do this via the command line. Unfortunately I only have Windows, and cannot install new software. type file1.txt file2.txt > out.txt allows me to almost get what I want, but I don't want the 1st line of file2.txt to be included in out.txt. I have noticed that more has the +n option to specify a starting line, but I haven't managed to combine these to get the result I want. I'm aware that this may not be possible in Windows, and I can always edit out.txt by hand to get rid of the line, but is there a simple way of doing it from the command line?

  • Display ALL categories that a product belongs to in Magento

    - by Jason
    I am conceptualizing a new Magento site which will have products that are included in several categories. What I am wondering is if I can display all categories a product is in on the product detail page. I know that it is possible to get the category, but is it possible to display a list of all categories which a product belongs to? For example, a shirt may be included in the Shirts category, as well as in Designers and Summer. Ideally, I would like to be able to display the following: More from:    Men Shirts    Men Designers Barnabé Hardy    Men Summer

  • is putting N in front of strings in scripts considered a "best practice"?

    - by jcollum
    Let's say I have a table that has a varchar field. If I do an insert like this: INSERT MyTable SELECT N'the string goes here' Is there any fundamental difference between that and: INSERT MyTable SELECT 'the string goes here' My understanding was that you'd only have a problem if the string contained a Unicode character and the target column wasn't unicode. Other than that, SQL deals with it just fine and converts the string with the N'' into a varchar field (basically ignores the N). I was under the impression that N in front of strings was a good practice, but I'm unable to find any discussion of it that I'd consider definitive. Title may need improvement, feel free.
