• Characters spilled over multiple columns in Oracle 11g?

  - by vicky21

  This is related to question: How to store unlimited characters in Oracle 11g? If maximum I need is 8000 characters, can I just add 3 more varchar2 columns so that I will have 4 columns with 2000 char each to get 8000 chars. So when the first column is full, values would be spilled over to the next column and so on. Will this design have any bad side effects? Please suggest.

• Magento - determine which xml layout file a page is using?

  - by John

  I tried reading the documentation but I still don’t really understand how magento's xml layout files work. In the directory app/design/frontend/default/modern/layout, i see a lot of xml files. How do I determine which xml file any given page on the website is using? For example, if I were on the home page at http://mysite.com, which layout xml file am I using? What if I’m on http://mysite.com/hello-world, which xml file then?

• jQuery: How can I work with dates in this format? mm/yyyy

  - by Enrique

  I'm doing a web application for articles Articles must be shown by month, with its published date stored as mm/yyyy Now: 1- Should I use a DATE type field for storing? 2- Will jQuery UI datePicker be useful for showing mm/yyyy? 3- How could I sort by mm/yyyy? I guess it will be more complicated if I store date normally and extract the day from date each time I want to do something, right? Thanks,

• Recommended way to make consistent form validation error prompt?

  - by Satoru.Logic

  Hi, all. In most web projects, we do both client-side and server-side form validation. A major part of form validation is error prompt, the client-side and server-side form validation library probably have implemented this for us, but the error prompt looks different. How can I design a consistent error prompt for such a system? Thanks in advance.

• When knowledge of "multithreading" is specified in a C++ job description, what is the expectation?

  - by Vaibhav Khattri

  I understand it should cover threading primitives (mutex, semaphore, condition variables etc.) plus design patterns (such as those specified in POSA2). But what's more? Every project has its own multithreading scenarios and one may have not dealt with those that the job is expecting?. So how does one build their knowledge and prove that they have the ability?

• FormsAuthentication AuthCookie data type

  - by FreshCode

  Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability? As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.

• Pass variables between separate instances of ruby (without writing to a text file or database)

  - by boulder_ruby

  Lets say I'm running a long worker-script in one of several open interactive rails consoles. The script is updating columns in a very, very, very large table of records. I've muted the ActiveRecord logger to speed up the process, and instruct the script to output some record of progress so I know how roughly how long the process is going to take. That is what I am currently doing and it would look something like this: ModelName.all.each_with_index do |r, i| puts i if i % 250 ...runs some process... r.save end Sometimes its two nested arrays running, such that there would be multiple iterators and other things running all at once. Is there a way that I could do something like this and access that variable from a separate rails console? (such that the variable would be overwritten every time the process is run without much slowdown) records = ModelName.all $total = records.count records.each_with_index do |r, i| $i = i ...runs some process... r.save end meanwhile mid-process in other console puts "#{($i/$total * 100).round(2)}% complete" #=> 67.43% complete I know passing global variables from one separate instance of ruby to the next doesn't work. I also just tried this to no effect as well unix console 1 $X=5 echo {$X} #=> 5 unix console 2 echo {$X} #=> "" Lastly, I also know using global variables like this is a major software design pattern no-no. I think that's reasonable, but I'd still like to know how to break that rule if I'd like. Writing to a text file obviously would work. So would writing to a separate database table or something. That's not a bad idea. But the really cool trick would be sharing a variable between two instances without writing to a text file or database column. What would this be called anyway? Tunneling? I don't quite know how to tag this question. Maybe bad-idea is one of them. But honestly design-patterns isn't what this question is about.

• The Relationship Between Activities and View Objects - Android

  - by Greenhouse Gases

  I am attempting to learn how to develop on the Android platform but do not quite understand the relationship between Activities and Views, because according to the documentation an Activity is link to a UI object that the user can interact with, but if this is the case where does the whole idea of Views come in? There is probably a very basic explanation but I would appreciate a few pointers all the same. Thanks

• How to make the WebBrowserto scroll up when new content is appended to the bottom of the page.

  - by Java Doe

  In order to achieve this effect, I would like to know how I can make the WebBrowser to scroll up when new content is added to the HTML page? "Allow more entries to be displayed in the view: When the user clicks more, additional entries should be displayed in addition to the ones which are already displayed. The code should cause the UI to scroll such that the first entry of the "more" set is on top". I am using com.ibm.rcp.browser.service.WebBrowser which is similar to SWT WebBrowser.

• Is it possible to produce a small preview or thumbnail image of a Crystal report in code?

  - by Lawrence Johnston

  I'm using Crystal to display the reports in my project, and I'd like to be able to display a small preview or thumbnail image of the report to the user when he or she is picking a report to display from my UI. Is there any way to produce these thumbnails dynamically from code? The user has the option to add or remove reports by adding or removing them from the reports folder, so just making all the thumbnail images by hand isn't really an option.

• Recommended lightweight jQuery lightbox plug-in?

  - by Mat Harden

  I need a lightbox plugin that is styled similar to FancyBox but will allow me to add text to the same white background as the image. Lightweight because I don't want many features as it's going to be added to an already heavy JS page. Preferably without Ajax features as I'll be handling this myself. Therefore I'm ruling out the use of Thickbox, Fancybox and jQuery UI. Basically I want the plugin to be a currently supported light-box jQuery plug-in that handles all the cross browser styling issues which I can then customise.
