• Detecting Requests from Mobile Browsers in ASP.NET

  - by Josh Stodola

  I have an existing web site and I would like to create a mobile version of it that is more suitable. For instance, the main site uses drop-down menus and we all know those are quite the fail on mobile devices. I would like to redirect to my mobile version (it will be a subdomain of the current site) if I detect a request from a mobile browser. So when they Google something and come to my site, they will automatically see the mobile version (just like Wikipedia). Does ASP.NET provide an easy way of doing this? If not, how can I do it?

• Markup filter wanted for a public website

  - by sibidiba

  Developing a community site where everyone can post text, I'm looking for a markup filter: What is not part of the markup must be escaped (htmlspecialchars()) as it is. Should turn URL-s automatically into links Should support some form of basic markups (bold, image, url, pre, list) Should have a simple parser, that turns user input text into HTML Content on the site is public to everyone, XSS must not allowed to happen. What do you suggest? What markup language in the first place? BBCode? Wiki? Markdown? Are there any complete API-s with good examples? PHP is available on the server side. If there is a WYSIWYG-like texarea in addition (like here on SO) that would be a fantastic bonus!

• Dreamweaver - template not recognising child files until they are opened

  - by Chris

  Hi I've got a new section for a website which I have generated for a data source and it has markup for using a Dreamweaver template. When I add the new files and folders to the site , then update my template , it doesn't find the new files to update. If I open one of the new files , make a change in the template , then it recognises the new file is using the template. So it's almost like I have to touch all the files with Dreamweaver first. I've tried to open all the new files which need to use the template but then Dreamweaver CS4 crashes, I presume because of the number of files it's opening. Anyway, does anyone know if there is a way to make Dreamweaver recognise that a block of new files belong to the template , it doesn't seem to just work automatically Thanks Chris

• Does Eclipse has a plugin for code clips like in Coda?

  - by Sinan Y.

  There is a very useful "Clips" feature in Coda, do we have such thing in Eclipse? What it does is pretty simple, you save once a code clip which you use very often and assign it a shortcut and when you want to re-use it on editor you type the shortcut you assigned and it automatically pastes that code clip and sets caret position to the defined position. On the example here (second image) when i write 4dom and press TAB afterwards it types me this... jQuery(function($){ //puts cursor here }); Since it is a very useful feature i miss that one on Eclipse, is there a plugin for this? Thanks, Sinan.

• How can I enable Vista/Win 7 theming/style for a ToolTip control?

  - by Joakim Hårsman

  In Windows Vista and Windows 7, ToolTips have a new visual style or theme, they are shiny grey metallic. How can I enable the new style for a ToolTip control? Some controls, like ListViews and ToolBars, use the new tooltips automatically, but other tooltips are rendered with the old yellow XP style. I've tried sending an TTM_SETWINDOWTHEME message but nothing happens and I'm not sure what string I am supposed to use for the visual style name. SetWindowTheme doesn't work either, I've used it successfully on ListViews and TreeViews to set the "Explorer" style (see http://www.danielmoth.com/Blog/TreeViewVista.aspx), but that doesn't seem to work on ToolTips. I'm using the plain win32 C API.

• vim command to restructure/force text to 80 columns

  - by wickedchicken

  I know there are ways to automatically set the width of text in vim using set textwidth (like http://stackoverflow.com/questions/235439/vim-80-column-layout-concerns). What I am looking for is something similar to = (the indent line command) but to wrap to 80. The use case is sometimes you edit text with textwidth and after joining lines or deleting/adding text it comes out poorly wrapped. Ideally, this command would completely reorganize the lines I select and chop off long lines while adding to short ones. An example: long line is long! short After running the command (assuming the wrap was 13 cols): long line is long! short If this isn't possible with a true vim command, perhaps there is a command-line program which does this that I can pipe the input to?

• Ruby fixtures error with password column

  - by user347998

  I am trying to load a fixture for my tests which has a password column (binary datatype). The tool i am using uses EzCrypto gem for encrypting and decrypting passwords before they are stored/retrieved. Now if my column is binary i thought rails would automatically store the password as encrypted - but all i get is: 1) Error: test_is_working(FirstTest): RuntimeError: Failed to decode the field. Incorrect key? /Library/Ruby/Gems/1.8/gems/mislav-will_paginate-2.3.11/lib/will_paginate/finder.rb:170:in method_missing' unit/first_test.rb:8:insetup' 2) Error: test_sanity(FirstTest): RuntimeError: Failed to decode the field. Incorrect key? unit/first_test.rb:8:in `setup' Fixture file looks like this: first_hussle: type: FirstAccount user: jsewq username: [email protected] password: 'abc123' any clues?

• Managing Unique IDs in stateless (web) DB4O applications

  - by Phil.Wheeler

  I'm playing around with building a new web application using DB4O - piles of fun and some really interesting stuff learned. The one thing I'm struggling with is DB4O's current lack of support for stateless applications (i.e. web apps, mostly) and the need for automatically-generated IDs. There are a number of creative and interesting approaches that I've been able to find that hook into DB4O's events, use GUIDs rather than numeric IDs or for whatever reason avoid using any system of ID at all. While each approach has its merits, I'm wondering if the less-elegant approach might equally be the best fit. Consider the following pseudo-code: If ID == 0 or null Set ID = (typeof(myObject)).Count myObject.Save It seems like such a blindingly simple approach, it's usually about here that I start thinking, "I've missed something really obvious". Have I?

• ZooKeeper and RabbitMQ/Qpid together - overkill or a good combination?

  - by Chris Sears

  Greetings, I'm evaluating some components for a multi-data center distributed system. We're going to be using message queues (via either RabbitMQ or Qpid) so agents can make asynchronous requests to other agents without worrying about addressing, routing, load balancing or retransmission. In many cases, the agents will be interacting with components that were not designed for highly concurrent access, so locking and cross-agent coordination will be needed to avoid race conditions. Also, we'd like the system to automatically respond to agent or data center failures. With the above use cases in mind, ZooKeeper seemed like it might be a good fit. But I'm wondering if trying to use both ZK and message queuing is overkill. It seems like what Zookeeper does could be accomplished by my own cluster manager using AMQP messaging, but that would be hard to get really right. On the other hand, I've seen some examples where ZooKeeper was used to implement message queuing, but I think RabbitMQ/Qpid are a more natural fit for that. Has anyone out there used a combination like this? Thanks in advance, -Chris

• Integrating virtual keyboard on a HP TouchSmart with an Adobe AIR app

  - by Alan

  Hi, Does anyone know if it's possible to integrate the ToushSmart's virtual keyboard with an Adobe AIR application? In most programs (Internet Explorer, Firefox, etc), when a user touches a text field a little keyboard icon automatically pops up which, when pressed, will bring up the virtual keyboard. However, this doesn't happen when clicking on text input fields in Adobe AIR applications. Has anyone had any experience working with AIR/Flash and touchscreens? Is there any API that can tell Windows (or the HP virtual keyboard specifically) that the user has clicked in a text field and that the virtual keyboard should be shown? The text fields are the standard kind (fl.controls.TextInput). Any suggestions would be greatly appreciated. Thanks in advance!

• How do I refresh TinyMCE for the code that I add with JavaScript

  - by Sam Kong

  Hi, I need to insert code for flash to TinyMCE with JavaScript. If I insert the same code using HTML menu of TinyMCE, it automatically add flash icon to the editor. But if I insert the code using JavaScript, the actual code is inserted but it shows nothing on the screen. One trick I found is toggle TinyMCE to normal textarea and back to TinyMCE. Then, it shows the flash icon. Is there a better way to do that? Thanks. Sam

• How to read integer in Erlang?

  - by Jace Jung

  I'm trying to read user input of integer. (like cin nInput; in C++) I found io:fread bif from http://www.erlang.org/doc/man/io.html, so I write code like this. {ok, X} = io:fread("input : ", "~d"), io:format("~p~n", [X]). but when I input 10, the erlang terminal keep giving me "\n" not 10. I assume fread automatically read 10 and conert this into string. How can I read integer value directly? Is there any way to do this? Thank you for reading this.

• Rhino - Set FEATURE_LOCATION_INFORMATION_IN_ERROR in code?

  - by Scott

  I'd like fileName, lineNumber and stack traces to automatically be provided by Rhino for any errors. I've been told that I need to set FEATURE_LOCATION_INFORMATION_IN_ERROR on the current context, but I'm not sure how to do this in code. Does anybody have an example of turning this feature on so that I can see stacktrace dumps on crashes? I'm using Rhino as part of Narwhal/Jack, and so that complicates things a bit, and I think the easiest way to at least get moving forward is if I can set it through code. Thanks.

• Replacing text in NSTextFieldCell inside NSTableView

  - by earl.ct

  Whenever a user would type a number, my app would automatically prepend a currency sign before that number. For example, when the user types "1" in a text field, the text inside it becomes "$1.00". All is good when I use an NSNumberFormatter, an NSTextField, and its delegate method control:didFailToFormatString:errorDescription:. - (BOOL)control:(NSControl *)control didFailToFormatString:(NSString *)string errorDescription:(NSString *)error { if ([[control formatter] isKindOfClass:[NSNumberFormatter class]]) { NSNumberFormatter *formatter = [control formatter]; if ([formatter numberStyle] == NSNumberFormatterCurrencyStyle && ! [string hasPrefix:[formatter currencySymbol]]) { NSDecimalNumber *new = [NSDecimalNumber decimalNumberWithString:string]; if (new == [NSDecimalNumber notANumber]) { new = [NSDecimalNumber zero]; } [control setObjectValue:new]; } } return YES;} Now I would like to have this functionality when a user types a number in a cell inside an NSTableView. I tried using control:didFailToFormatString:errorDescription: but the cell would erase the text instead.

• VB.Net: How to fill in a form in a website, then click at a button and download the file using webbr

  - by BasisBit

  I am using a WebBrowser-Control to fill in a webform and then click at a button, this currently results in a standard Download File Dialog (you get these if you download a file using internet explorer), but instead, I have to catch this file and save it automatically with a by me defined name to a specific folder. I am trying to code a little application in vb.net which download the Export-file from my wordpress-blog, and I want to do this completely without user-interaction. Currently everything works, except the downloading of the file. I tried to catch it with the event System.Windows.Controls.WebBrowser.Navigating(ByVal Object, ByVal System.Windows.Navigation.NavigatingCancelEventArgs) but I don't see where to download the file from :( I hope you guys can help me.

• Using 'load' in octave

  - by lollygagger

  Is there a way to tell the load function to only load until a certain line? I want to read in a data file and assign the numbers to an array, however, I want it to stop after it has created a 200 X 200. Could I also do this with a do-while loop and fgetl? When I try to use fgetl(fid, len) and give it 'len', it does not obey :-/ How can I tell octave to ignore the comment lines in an input file? They are '#' characters, so I figured octave would just automatically ignore them, but not so... Thanks.

• How to pre-process CSV data for FasterCSV?

  - by Katherine Chalmers

  We're having a significant number of problems creating a bulk upload function for our little app. We're using the FasterCSV gem to upload data to a MySQL database but he Faster CSV is so twitchy and precise in its requirements that it constantly breaks with malformed CSV errors and time out errors. The csv files are generally created by users' pasting text from their web sites or from Microsoft Word docs so it is not reasonable to expect that there will never be odd characters like smart quotes or accents in the data. Also users aren't going to be readily able to identify whether their data is perfect enough for FasterCSV or not. We need to find a way to fix it for them automatically. Is there a good way or a reliable tool for pre-processing CSV data to fix any nits in the data before having the FasterCSV gem process it?

• Inscribe and center an image within a frame

  - by Brennan Roberts

  Given a div of arbitrary aspect ratio, what's the best way to place and style an image (also with an arbitrary aspect ratio) inside such that: It is both inscribed and centered Its dimensions and position are set using relative values so that the image will remain inscribed and centered automatically when the frame is uniformly scaled (javascript should only be required when the image is initially inserted, or if the frame's aspect ratio changes) Extra markup is minimized Here's the result we want: Here's a fiddle template, which is just: Markup Should pillarbox <div class="frame"> <img src="http://www.placekitten.com/200/300" /> </div> Should letterbox <div class="frame"> <img src="http://www.placekitten.com/300/200" /> </div> CSS .frame { width: 200px; height: 200px; border: 2px solid black; margin: 10px 0px 100px 0; }

• Add JSON support to Rails app

  - by Meltemi

  I am experimenting with Rails and was wondering what's needed to allow/add support for JSON requests? I have a vanilla installation of Rails 2.3.5 and the default scaffolding seem to provide support for HTML & XML requests but not JSON. class EventsController < ApplicationController # GET /events # GET /events.xml def index @events = Event.all respond_to do |format| format.html # index.html.erb format.xml { render :xml => @events } end end # GET /events/1 # GET /events/1.xml def show @event = Event.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @event } end end ... I'm new to this but it would appear as though i would need to add a format line in each method along the lines of: format.js { render :js => @event.json } couldn't this be done automatically? perhaps there's a template somewhere i need to update...or a flag i can set? Or perhaps, and most likely, I've missed the boat entirely?!?

• add schema to path in postgresql

  - by veilig

  I'm the process of moving applications over from all in the public schema to each having their own schema. for each application, I have a small script that will create the schema and then create the tables,functions,etc... to that schema. Is there anyway to automatically add a newly created schema to the search_path? Currently, the only way I see is to find the users current path SHOW search_path; and then add the new schema to it SET search_path to xxx,yyy,zzz; I would like some way to just say, append schema zzz to the users_search path. is this possible?

• a better way to initialize database ONCE when rail server starts

  - by Hadi

  i would like to initialize database the first time the server is started, that involve calling a class method. Given the class name is: Product At first i put an .rb file config\initializers\init.rb as it gets automatically called. Everything works ok, until the database is deleted, and i am trying to do rake db:migrate. rake db:migrate fails saying that cannot find 'product' table. inside init.rb = Product.populate_db The solution i came up is: I took out init.rb do rake db:migrate put back init.rb run the server. My rails application is mainly for reporting and the data is seeded from other application, so i have to do the above step everyday Is there a better way to do the initialization?

• Can I pass an argument to a VBScript (vbs file launched with cscript)?

  - by Peter

  I have this script saved in "test.vbs": Set FSO = CreateObject("Scripting.FileSystemObject") Set File = FSO.OpenTextFile(workFolder &"\test.txt", 2, True) File.Write "testing" File.Close Set File = Nothing Set FSO = Nothing Set workFolder = Nothing When I run the script I want to pass the value of the "workFolder" variable. How can I do this? Can I do it? Something like "cscript test.vbs workFolder:'C:\temp\'" perhaps? Bonus question: Is it neccessary to clean up the passed variable with "Set workFolder = Nothing" or does VBSCript do that automatically when it terminates? Maybe "Set File = Nothing" and "Set FSO = Nothing" is unneccessary also? Please let me know if you know the answer to both these questions.

• AJAX with Web services and ASP.NET SessionState

  - by needhelp1

  We have an application which uses ScriptManager to generate a client-side proxy which makes AJAX calls to web services. The web services being invoked live in a separate appDomain(separate cluster altogether). The problem is that our application uses a State server for storing session. I want the web services to be able to access session also. First off, does anyone see anything wrong with the client making web service calls to a separate cluster(we're hoping this would be a better approach for scalability)? I was thinking that possibly anytime there is an update to the session dictionary in one appDomain, automatically update the session in the other appDomain also(referring to the web service appDomain, don't know how to do this, only theoretical). What do others think? Thanks!
