• How can I give some basic text editing functionality to a firefox plugin?

  - by roddik

  Hello. I'm writing a plugin to Firefox, which is basically a sidebar, that is filled with yaml-formatted information based on what user does on the page (just another web testing solution). I want to enable user to change generated text manually right in the sidebar and: Add code-folding (folding click: \n text: some text to a single line) Add highlighting of registered actions (click, fill and so on) and unregistered actions (syntax errors) How do I do that? Is placing an iframe to the sidebar and trying to do that with html/js the best solution (seen it in a similar one)? As you may have noticed, I'm a newbie in plugin writing, so please excuse if anything.

• Use parameters with CTL

  - by Hal

Currently, I launch the loader file using the following command line: sqlldr user/pwd@db data=my_data_file control=my_loader.ctl I would like to know if it is possible to use specify parameters to be retrieved in the CTL file. Also, is it possible to retrieve the name of the data file used by the CTL to fill the table ?I also would like to insert it for each row.

• What is the proper way to check the previous value of a field before saving an object? (Using Django

  - by anonymous coward

  I have a Django Model with updated_by and an approved_by fields, both are ForeignKey fields to the built-in (auth) User models. I am aware that with updated_by, it's easy enough to simply over-ride the .save() method on the Model, and shove the request.user in that field before saving. However, for approved_by, this field should only ever be filled in when a related field (date_approved) is first filled in. I'm somewhat certain that I can check this logically, and fill in the field if the previous value was empty. What is the proper way to check the previous value of a field before saving an object? I do not anticipate that date_approved will ever be changed or updated, nor should there be any reason to ever update the approved_by entry. UPDATE: Regarding forms/validation, I should have mentioned that none of the fields in question are seen by or editable by users of the site. If I have misunderstood, I'm sorry, but I'm not sure how forms and validation apply to my question.

• Is it better to store user text (such as a blog entry or private messages) in the database or as flat files?

  - by Fredashay

  I'm building a social networking type site that will be storing large chunks of text that's entered by users, such as blog entries and private messages. As such, these will be entered once, with minimal revisions, but many reads by multiple users over time. I'm using MySQL, by the way. My concerns are: Storing large blocks of text on the database will fill the database to capacity eventually. I read somewhere that storing user text in flat files is a security risk? (The filenames will be generated dynamically by the PHP, not by the user.) Storing them as text files may cause them to become out of sync if I ever have to reinitialize the database and restore it from backups. What are all your thoughts and advice, pros and cons?

• Javascript Code For HTML5 Form Validation Not Working

  - by MistUnleashed

  I'm new to JavaScript so I have no idea why this code does not work and validate my HTML5 Form like it should. The JavaScript code which can be found below is supposed to check if the browser supports the required attribute and if it doesn't then it will validate the form and check for any empty spaces. I got the code from this website. In the body of the webpage containing my form I have this: Below is the contactvalidate.js file: $('#formTemplate').submit(function() { if (!attributeSupported("required") || ($.browser.safari)) { $("#formTemplate [required]").each(function(index) { if (!$(this).val()) { alert("Please fill all required fields."); return false; } }); } return false; }); Do I need to change anything in this code or should it work? As I've said I'm new to JavaScript so any help you guys could give me is greatly appreciated.

• How to maintain 2 lists of object

  - by michael

  Hi, My c++ program needs to maintain 2 list of objects. list inuse; list free; So objects A can even in 'inuse' list or in 'free' list, but not both. http://www.cplusplus.com/reference/stl/list/ I am think of using 'list' as the data structure for my lists. My questions are 1. why i can't randomly access an elmenet in the list, I look at the above api, I don't see a way to get inuse[2]; 2. How can I remove an element in the list? There is an erase(), but how can I use it to remove element #2? And after I remove element 2? will STL list fill the erased spot automatically? e.g. #3 will become #2, #4 will become #3 and so on? Thank you.

• How would I go about writing a conditional statement to check if visitor is coming from a particular

  - by Matthew

  Hello guys, What I have in mind is this... We are going to have people come from a particular site during a acquisition campaign and was wondering how I could conditionalize a certain section of my site to display a thank you message instead of the sign up form as they would have had the opportunity to fill this out before coming to my landing page. I have seen solutions like: $referal = mysql_real_escape_string($_SERVER['HTTP_REFERER']); I would like to know if this is the best way to get this to work??? - okay this is what i think might work. The third party website that is referring people to our landing page once the form on that site has been filled out can push into the record a hidden input value of "www.sample.com" or whatever... then I can have something check the for that particular value and fire off the conidtional. Does that even sound right?

• Efficient way to update all rows in a table

  - by m_pGladiator

  Hi, I have a table with a lot of records (could be more than 500 000 or 1 000 000). I added a new column in this table and I need to fill a value for every row in the column, using the corresponding row value of another column in this table. I tried to use separate transactions for selecting every next chunk of 100 records and update the value for them, but still this takes hours to update all records in Oracle10 for example. What is the most efficient way to do this in SQL, without using some dialect-specific features, so it works everywhere (Oracle, MSSQL, MySQL, PostGre etc.)?

• Getting all inner classes by reflection

  - by Roman

  I have the following problem. I have this pretty class and now I want to get all the classes that extend that class (inner classes ) and fill 'classList' with it. ( in an automatic way of course ) public abstract class CompoundReference { private static List<Class<? extends CompoundReference>> classList = new ArrayList<Class<? extends CompoundReference>>(); @CompoundKey(gsType = User.class, dbType = UserDetailsMappings.class) public static class CUser extends CompoundReference { } @CompoundKey(gsType = Catalog.class, dbType = CatalogDetailsMappings.class) public static class CCatalog extends CompoundReference { } @CompoundKey(gsType = Product.class, dbType = ProductDetailsMappings.class) public static class CProduct extends CompoundReference { } @CompoundKey(gsType = Category.class) public static class CCategory extends CompoundReference { } @CompoundKey(gsType = Poll.class, dbType = PollDetailsMappings.class) public static class CPoll extends CompoundReference { } // much mroe inner classes Some manual solution would be just to main such a static block , that is something that I dont want to do. static { classList.addAll(Arrays.asList(CUser.class, CCatalog.class, CProduct.class, CCategory.class, CPoll.class, CComment.class, CWebPage.class, CReview.class, CPost.class, CMessage.class, CStory.class,CPicture.class)); }

• Question about inserting/updating rows with SQL Server (ASP.NET MVC)

  - by Alex

  I have a very big table with a lot of rows, every row has stats for every user for certain days. And obviously I don't have any stats for future. So to update the stats I use UPDATE Stats SET Visits=@val WHERE ... a lot of conditions ... AND Date=@Today But what if the row doesn't exist? I'd have to use INSERT INTO Stats (...) VALUES (Visits=@val, ..., Date=@Today) How can I check if the row exists or not? Is there any way different from doing the COUNT(*)? If I fill the table with empty cells, it'd take hundreds of thousands of rows taking megabytes and storing no data.

• How can I delete a file in Sinatra after it has been sent via send_file?

  - by John Reilly

  I have a simple sinatra application that needs to generate a file (via an external process), send that file to the browser, and finally, delete the file from the filesystem. Something along these lines: class MyApp < Sinatra::Base get '/generate-file' do # calls out to an external process, # and returns the path to the generated file file_path = generate_the_file() # send the file to the browser send_file(file_path) # remove the generated file, so we don't # completely fill up the filesystem. File.delete(file_path) # File.delete is never called. end end It seems, however, that the send_file call completes the request, and any code after it does not get run. Is there some way to ensure that the generated file is cleaned up after it has been successfully sent to the browser? Or will I need to resort to a cron job running a cleanup script on some interval?

• What happens to other users if the .NET worker process crashes?

  - by Jason Slocomb

  My knowledge of how processes are handled by the ASP.Net worker process is woefully inadequate. I'm hoping some of the experts out there can fill me in. If I crash the worker process with a System.OutOfMemoryException, what would the user experience be for other users who were being served by the same process? Would they get a blank screen? 503 error? I'm going to attempt to test this scenario with some other folks in our lab, but I thought I would float this out there. I will update with our results.

• Checking if the email had been already taken in the following if statement (Rails)?

  - by alexchenco

  I have the following action: users.rb: def omniauth_create auth = request.env["omniauth.auth"] user = User.from_omniauth(env["omniauth.auth"]) unless user.email.blank? if user.id.nil? # Save the user since he hasn't been created yet user.save! end sign_in user redirect_back_or user else # Send user to a form to fill his email #session[:omniauth] = request.env['omniauth.auth'].except('extra') redirect_to(enter_email_path(oprovider: user.provider, ouid: user.uid, oname: user.name, opassword: user.password, opassword_confirmation: user.password)) end end It does the following: If the user's email is not blank, sign him in, and redirect him to his profile (and save him if his id is nil. In other words, if he hasn't been created yet). If the user's email is blank, send him to enter_email_path (where the user can enter his email). Now I want to add another if statement that flashes an error if the email had been already taken, and redirects the user to the root_path I'm not very sure how to do this, Any suggestions? (and where to put that if statement?)
