    How Do I disable the copy paste feature in my webpage. To be precise, I don't want my users to copy any information from my website and use them for personal purposes. The previous question on the same topic doesn't give enough explanation. The onselect and ondrag aren't working. Please help.

  • How to disable a container and its children in Swing

    - by Fuzzy76
    I cannot figure out a way to disable a container AND its children in Swing. Is Swing really missing this basic feature? If I do setEnabled(false) on a container, its children are still enabled. My GUI structure is pretty complex, and doing a traversion of all elements below the container is not an option. Neither is a GlassPane on top of the container (the container is not the entire window).

  • Define Rails Model Persistent Attributes in Model File

    - by Kevin Sylvestre
    I recently played with MongoDB in Rails using Mongoid. I like the ability to define attributes for models within the model file (as opposed to in migrations): class Person include Mongoid::Document field :name, :type => String field :birthday, :type => Date end For projects that cannot use a schema-less database, does a similar feature exist? Any gems or plugins that generate schemas from a similar syntax would be greatly appreciated. Thanks.

  • What is the proper odbc command for calling Oracle stored procedure with parameters from .Net?

    - by Hamish Grubijan
    In the case of MSFT SQL Server 08, it is: odbcCommand = new OdbcCommand("{call " + SP_NAME + " (?,?,?,?,?,?,?) }", odbcConn); When I try to do the same thing for Oracle, I get: OdbcException: ERROR [HYC00] [Oracle][ODBC]Optional feature not implemented. Feel free to ask for clarification, and please help. I am using .Net 3.5, SQL Server 08, and Oracle 11g_home1. P.S. The Oracle stored procedure does have some 3 more parameters, but I believe I am handling this in my code.

  • jQuery drawing and modifying lines and positions

    - by Chris
    I want to allow people to select a feature region on an image using jQuery. This should work similarly to the Facebook tagger except once someone "tags" an area of the image an ellipse should appear with the ability for the user to rotate and scale it. How can I achieve this using jQuery?

  • Making a CMS extendable by plugins - examples

    - by Anant
    I'm working on an open source script. I would like to provide a feature to extend the script by use of plugins/modules. I need some recommendations on open source cms/scripts to study code from, to gather the best practices on making script extendable by plugins. I've used WordPress in the past, and was planning to implement a similar system, but I'm looking to dive into alternatives, which might be better. Language preferred is PHP 5

  • Change video being played in HTML5 video

    - by Krt_Malta
    Hi! I'm using the tags in HTML5 to play a video on a web browser... (and I'm very impressed with this new feature) Is there the functionality to change the video being played through Javascript? Say when I select another video from a list, a Javascript function would be called which would contain something on the lines of MyVideo.VideoLocation = //location of new video to be played. Is this possible please? Thanks and regards, Krt_Malta

  • I work on local copies of files and upload them to a remote server on save. What version control sys

    - by 10goto10
    Here's my situation: My files are on a remote server (Linux). When I want to edit a file at home on my Windows machine, my editor (PSPad) downloads a copy. When I save the document, my editor uploads it to the server, overwriting the previous version. Is there a version control system, preferably GUI driven, that can handle this situation? Additional info: I probably can't install elaborate software on the remote server, but can on my own computer. Concurrent Versions System (CVS) is installed on the remote server. Uploading/downloading goes through an FTP-to-SFTP bridge set up with Bitvise Tunnelier.

  • Preventing cross-site scripting in ASP.NET MVC - using jQuery or standard HtmlHelpers

    - by user313353
    I am building an ASP.NET MVC application that is AJAX-driven. For some reason I need to add some DOM elements on the fly when clicking a submit button. This is accomplished with jQuery.append(). One element inserted is a textarea, whose the data must be parse before submitting to ensure that no cross-site scripting can be done. We know that the Html.Encode() works great but must be declared outside a script tag. All I have done with jQuery is embedded within a script tag. 1) Is there a way to take advantage of the Html.Encode() within a script tag? 2) How can I accomplish this with jQuery? At worst I can use HttpUtility.HtmlEncode(), which is called on the server-side. Thanks for your help. Roland

  • Getting started with mvim, how to manage a project?

    - by zengr
    Hi, I have started out with macvim and now fairly comfortable with the navigation (on a single file) and now I need to write a whole project (say rails) using mvim. In textmate, you have mate project_dir which opens the project in a side drawer, so my question is: Is there a similar feature in mvim? How can a complete project managed in traditionally in macvim? Links to some write-ups are welcomed.

  • R: preventing unlist to drop NULL values

    - by nico
    I'm running into a strange problem. I have a vector of lists and I use unlist on them. Some of the elements in the vectors are NULL and unlist seems to be dropping them. How can I prevent this? Here's a simple (non) working example showing this unwanted feature of unlist a = c(list("p1"=2, "p2"=5), list("p1"=3, "p2"=4), list("p1"=NULL, "p2"=NULL), list("p1"=4, "p2"=5)) unlist(a) p1 p2 p1 p2 p1 p2 2 5 3 4 4 5

  • Is it Bad Practice to use C++ only for the STL containers?

    - by gmatt
    First a little background ... In what follows, I use C,C++ and Java for coding (general) algorithms, not gui's and fancy program's with interfaces, but simple command line algorithms and libraries. I started out learning about programming in Java. I got pretty good with Java and I learned to use the Java containers a lot as they tend to reduce complexity of book keeping while guaranteeing great performance. I intermittently used C++, but I was definitely not as good with it as with Java and it felt cumbersome. I did not know C++ enough to work in it without having to look up every single function and so I quickly reverted back to sticking to Java as much as possible. I then made a sudden transition into cracking and hacking in assembly language, because I felt I was concentrated too much attention on a much too high level language and I needed more experience with how a CPU interacts with memory and whats really going on with the 1's and 0's. I have to admit this was one of the most educational and fun experiences I've had with computers to date. For obviously reasons, I could not use assembly language to code on a daily basis, it was mostly reserved for fun diversions. After learning more about the computer through this experience I then realized that C++ is so much closer to the "level of 1's and 0's" than Java was, but I still felt it to be incredibly obtuse, like a swiss army knife with far too many gizmos to do any one task with elegance. I decided to give plain vanilla C a try, and I quickly fell in love. It was a happy medium between simplicity and enough "micromanagent" to not abstract what is really going on. However, I did miss one thing about Java: the containers. In particular, a simple container (like the stl vector) that expands dynamically in size is incredibly useful, but quite a pain to have to implement in C every time. Hence my code currently looks like almost entirely C with containers from C++ thrown in, the only feature I use from C++. I'd like to know if its consider okay in practice to use just one feature of C++, and ignore the rest in favor of C type code?

  • Does Eclipse have line-wrap

    I'm editing an XML file with the Eclipse IDE and need to input paragraphs of text. It doesn't seem that eclipse has a line-wrap feature though. Anyone knows if it does or if there's a plugin for that?

  • When to delete newly deprecated code?

    - by John
    I spent a month writing an elaborate payment system that handles both credit card payments and electronic fund transfers. My work was used on production server for about a month. I was told recently by the client that he no longer wants to use the electronic fund transfer feature. Because the way I had to interface and communicate with the credit card gateway is drastically different from the electronic fund transfer api (eg. the cc company gives transaction responses immediately after an http request, while the eft company gives transaction responses 5 business days after an http request), I spent a lot of time writing my own API to abstract common function calls like function payment(amount, pay_method,pay_freq) function updateRecurringSchedule(user_id,new_schedule) etc.. Now that the client wants to abandon the EFT feature, all my work for this abstracted payments API is obsolete. I'm deliberating over whether I should scrap my work. Here's my pro vs. con for scrapping it now: PRO 1: Eliminate code bloat PRO 2: New developers do not need to learn MY API. They only need to read the CC company's API PRO 3: Because the EFT company did not handle recurring payment schedules, refunds, and validation, I wrote my own application to do it. Although the CC company's API permitted this functionality, I opted to use mine instead so that I could streamline my code. now that EFT is out of the picture, I can delete all this confusing code and just rely on the CC company's sytsem to manage recurring billing, payment schedules, refunds, validations etc... CON 1: Although I can just delete the EFT code, it still takes time to remove the entire framework consolidates different payment systems. CON 2: with regards to PRO 3, it takes time to build functionality that integrates the payment system more closely with the CC company. CON 3: I feel insecure deleting all this work. I don't think I'll ever use it again. But, for some inexplicable reason, I just don't feel comfortable deleting this work "right now". So my question is, should I delete one month's worth recent development? If yes, should I do it immediately or wait X amount of time before doing so?

  • VS2010 almost always zooms text on scroll

    - by Chris Barr
    You know the neat text zoom feature in VS2010 where you hold down Ctrl and then use your scroll wheel? Well, this seems to happen by default (and without ever pressing Ctrl) to nearly every file I open. Usually I open a file and have to scroll to some lower point, but instead it starts zooming the text! I have found that by tapping the Ctrl key VS then realizes that it should scroll instead of zoom, but it's still very annoying. Any ideas?

    I'd like to learn other people workflow when using either SVN or GIT. Please describe your strategy to handle the following tasks: Implement a feature Fixing bugs (during development and deployed app) Code Review Refactoring code (post code-review) Incorporate patches Releasing the newer version of your app (desktop, web, mobile, would you treat them differently?) Feel free to organize your answer not grouped by the tasks but grouped by whatever you think is relevant but please organize it by VCS/DVCS (please don't mix them). Thank you.
