  • jQuery DOM append losing markup

    - by Raj
    This is related to an earlier question. I try to append HTML DOM returned in an AJAX response to an existing DIV. I see all the text, but it seems all markup such as bold, italic, etc is lost. My AJAX (XML) data is like so: <event source="foo"> <contents> <h1>This is an event</h1> This is the body of the event </contents> </event> My jQuery code does this: $("#eventDiv").append( jData.find("contents").contents().clone() ); Attempting to do .html() on the cloned contents throws an exception: TypeError: Cannot call method 'replace' of undefined. I am a little surprised that it is so excruciatingly hard to do this with jQuery. Am I doing something too far off the track?

  • How to get the "#" symbol in the :id into the redirect_to method in Rails

    - by Matthias Günther
    Hello, this is a silly questions but I don't understand, why rails isn't evaluating my string as expected. Here is my problem: I want to redirect to an url in the form ~/:controller/index/#_76 redirect_to :action => "index", :id => '#_76' But I'm getting the url in the form: ~/:controller/index/%25_76 and so my anchor for linking to a certain place in the website isn't working. Can someone please explain me, why rails makes this rendering? I think this hase something to do with url encoding. Again thanks for your help, I'm learning every day a little bit more about rails :).

  • C++ How do I properly use getline for ifstream members.

    - by John
    Ok so I have a problem with getline. I have a file that contains a couple strings. I created it by myself and I have each string on a seperate line. Ex. textfile.txt Line 1 Line 2 Line 3 Line 4 //Little snip of code ifstream inFile("textfile.txt"); getline(inFile, string1); When I debug the program and ask it to print out string1 it shows that "Line 1\r" is saved into string1. I understand that it's from me actually hitting enter when I created the file. This problem causes my program to have a segmentation fault. I know my code works because if I use ofstream to write the file first and then i read it in, it works. So for my quesiton, is their anyway to use the getline function without it picking up the escape sequence \r? If i am not clear just let me know.

  • Looking for some Feedback on a DB Design

    - by zSysop
    I'm currently working on a ticketing system which allows our users to submit tickets based on their own needs. i.e. if Department "A" is submitting a ticket they can have certain types of problem categories (such as "Supplies" or "Printer") along with details pertaining to the chosen category. I have laid out a partial db design and i was looking for some feedback on it. I've never built a system from the ground up by myself so i'm a little bit nervous. here's my a draft version of my db design Issues Table Id | CreatedBy | CreateDate | Status | Owner | AssignedTo | AssignmentDate | ----------------------------------------------------------------------------- EquipmentIssueDetails Table Id | IssueId | Serial # | Make | Model | .... --------------------------------------------- SupplyIssueDetails Table Id | IssueId | SupplyId | ItemId | QTY | UnitOfMeasurement ------------------------------------------------------------- NetworkIssueDetails Table Id | IssueId | Supervisor | Details | ------------------------------------------------------------- Notes Table Id | IssueId | Note | CreatedBy | CreateDate ------------------------------------------------------------- Thanks in advance

  • Is *not* using the asp.net membership provider a bad idea?

    - by EJB
    Is it generally a really bad idea to not use the built-in asp.net membership provider? I've always rolled my own for my asp.net apps (public facing), and really have not had any problems in doing so. It works, and seems to avoid a layer of complexity. My needs are pretty basic: once setup, the user must use email address and password to login, if they forget it, it will be emailed back to them (a new one). After setup there is little that needs to be done to each user account, but I do need to store several extra fields with each user (full name, telephone and a few other fields etc). The number of users that required login credentials are small (usually just the administrator and a few backups), and everyone else uses the site unauthenticated. What are the big advantages that I might be missing out on by skipping the asp.net membership provider functionality?

  • Parsing and validating arbitrary date formats in ruby (on rails)

    - by Matt Briggs
    I have a requirement to handle custom date formats in an existing app. The idea is that the users have to do with multiple formats from outside sources they have very little control over. We will need to be able to take the format and both validate Dates against it, as well as parse strings specifically in that format. The other thing is that these can be completely arbitrary, like JA == January, FE == February, etc... to my understanding, chronic only handles parsing (and does it in a more magical way then I can use), and enter code here DateTime#strptime comes close, but doesn't really handle the whole two character month scenario, even with custom formatters. The 'nuclear' option is to write in custom support for edge cases like this, but I would prefer to use a library if something like this exists.

  • Recreating iPhone stock application with nested views

    - by john
    I am trying to create an app similar to the Yahoo Stocks app that comes on the iPhone, with the split-screen interface (table on the top, graph on the bottom). I'm struggling with the view hierarchy. What is the easiest way to implement a split-screen type of application. I basically want two views nested in a parent view. My problem is a little bit more complex because I want functionality like having a uipagecontrol (does this require another viewcontroller, or is simply implemented in the initial view controller)? To what degree do I need to use IB? I would prefer to do this all in Xcode. Thanks in advance!

  • jQuery plugin: Validation can't be customized without setting all fields to 'required'?

    - by rasx
    I've spent the day looking at jQuery plugin: Validation by Jörn Zaefferer. I notice that it works fine as long as you call the validate() method without options. In my little squalid world, as soon as I add options, like errorPlacement, I notice that validation ignores form fields that are not marked required. I also notice that many, many demos mark all fields required---or do not pass options. Am I writing about anything familiar here? Or should I astral project to a parallel universe?

  • Need to know who is hogging my bandwidth?

    - by Dev
    I have an ethernet connection to my iMac and with Internet sharing I am broadcasting the wireless network from my mac rather than using a wireless router. I use it to connect other devices wirelessly to the internet. But this makes all the traffic flow through my iMac. I wanted a way to analyze the traffic so that I know what connected devices are hogging the bandwidth at a given time and from which websites? I installed wireshark for mac and played around a little but it seems like an overkill when you first look at it. Can someone please help with few instructions to get what I need or any other way other than using wireshark? Thanks Dev.

  • Is MVC now the only way to write PHP?

    - by JasonS
    Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

  • Sending mail via sendmail from python

    - by Nate
    If I want to send mail not via SMTP, but rather via sendmail, is there a library for python that encapsulates this process? Better yet, is there a good library that abstracts the whole 'sendmail -versus- smtp' choice? I'll be running this script on a bunch of unix hosts, only some of which are listening on localhost:25; a few of these are part of embedded systems and can't be set up to accept SMTP. As part of Good Practice, I'd really like to have the library take care of header injection vulnerabilities itself -- so just dumping a string to popen('/usr/bin/sendmail', 'w') is a little closer to the metal than I'd like. If the answer is 'go write a library,' so be it ;-)

  • Best Website Statistics tool for Drupal

    - by Olav
    What is the best free Website statistics setup I can have for Drupal 6 on Apache? Particularities: 1. Multisite install. Might want to look over several sites. Should be able to restrict view for clients to their own site. Some hits are bypassing Drupal. Some urls are not public. Some sites have little traffic, it would be nice to be able to exclude "own" traffic. Logged in users are not so important (It seems Google Analytics is popular)

  • jquery - deciding whether a user is "away"

    - by Phil Jackson
    hi, im doing a little test to check whether the user is "away" (unactive) or not; function away_status(){ $("#away_stat_update").everyTime(1000, function(i) { var number = Number($(this).html()); if( number == 20 ) { // set user as away alert( "user away" ); } if( number > 20 ) { $("*").mousemove(function(e){ $("#away_stat_update").html(0); var number = Number(0); // reset user to being online alert( "user back online" ); }); } $("#away_stat_update").html( number + 1 ); }); $("*").mousemove(function(e){ $("#away_stat_update").html(0); }); } away_status(); the only problem is that when the number is greater than 20 and the mouse is moved it keeps alerting "user back on line" instead of doing it just once. The number is resetting by the way.

  • How to programmatically launch a chromecast app from command line

    - by pushmatrix
    I want to launch a Chromecast app but NOT using the chrome extension or iOS or Android. Doing this from command line. I noticed that you can send a POST to your chromecast, and it will launch an app. For example if I do curl -H “Content-Type: application/json” http://CHROMECAST_IP:8008/apps/YouTube -X POST -d ‘v=oHg5SJYRHA0' Then it will start up youtube. But for some reason I can't do this with custom apps (in dev mode). I thought I'd be able to send a POST to http://CHROMECAST_IP:8008/apps/MY_REGISTERED_APP_ID, but no luck. I just get a 404 response. Hmmm... My app is just a simple webpage (it is not streamed media). I want to run a little headless server that starts my chromecast app everyday via a CRON task. Any help is greatly appreciated! Thanks :)

  • Get a random name and number (same contact) from an iPhone users address book

    - by Sam Jarman
    Hi there, I have had only very little experience using the address book in the iPhone SDK. Does anyone have a code snippet or knows the code to get a persons name and number Eg 'Fred Smith - 027 292 2112". I haven't had much luck with the stuff I've tried. I want to achieve this programmatically, and not let the user decide (random pick of the person). I also don't want to display the contact picker either any tutorial links, or anything would be appreciated. Thanks in advance Sam

  • Standard (cross-platform) way for bit manipulation

    - by Kiril Kirov
    As are are different binary representation of the numbers (for example, take big/little endian), is this cross-platform: some_unsigned_type variable = some_number; // set n-th bit, starting from 1, // right-to-left (least significant-to most significant) variable |= ( 1 << ( n - 1 ) ); // clear the same bit: variable &= ~( 1 << ( n - 1 ) ); In other words, does the compiler always take care of the different binary representation of the unsigned numbers, or it's platform-specific? And what if variable is signed integral type (for example, int) and its value is zero positive negative? What does the Standard say about this? P.S. And, yes, I'm interesting in both - C and C++, please don't tell me they are different languages, because I know this :) I can paste real example, if needed, but the post will become too long

  • Question About Abstract Classes?

    - by IbrarMumtaz
    URL: Link (1) According to this wesbite .. you cannot implement Abstract classes but derive from them. This makes sense and I have read this many times. Like an interface, you cannot implement an instance of an abstract class, however you can implement methods, fields, and properties in the abstract class that can be used by the child class. But on MSDN URL: TextWriter CLass on MSDN TextWriter is an abstract class but it has two constructors defined ... and according to the MS 70-536 book, the following statement is valid: TextWriter tw = new File.CreateText("myFile.Txt") The static file class and it's CreateText method is fine by me as I have studied it on MSDN but can somebody explain this little contradiction I have found? Surely I am not the first? Why is instantaion of base abstract classes possible????

  • Helping managers and customers understand SOA

    - by David
    I frequently hear Service-Oriented Architecture (SOA) being tossed around as a buzzword among non-technical customers or program managers with little concern or understanding for what it actually entails (example: "Can I buy a SOA?"). There's also a lot of misinformation about SOA (example: "Only web apps can use SOA") and a general lack of understanding for its capabilities (example: "SOA can make your make all of your data work together"). What are some key facts that you, as someone who understand the technical side of SOA, use to educate program managers on the appropriate use and understanding of SOA? What's the best way to set the record straight with non-technical folks?

  • Draw and move a point over an image in python

    Hi all I have to do a little script in Python. In this script I have a variable (that represents a coordinate) that is continuously updated to a new value. So I have to draw a red point over a image and update the point position every time the variable that contains the coordinate is updated. I tried to explain what I need doing something like this but obviously it doesn't works: import Tkinter, Image, ImageDraw, ImageTk i=0 root = Tkinter.Tk() im = Image.open("img.jpg") root.geometry("%dx%d" % (im.size[0], im.size[1])) while True: draw = ImageDraw.Draw(im) draw.ellipse((i, 0, 10, 10), fill=(255, 0, 0)) pi = ImageTk.PhotoImage(im) label = Tkinter.Label(root, image=pi) label.place(x=0, y=0, width=im.size[0], height=im.size[1]) i+=1 del draw someone may help me please? thanks very much!

  • How to create a "dependency graph" for IT assets

    - by p.marino
    One of my customers is trying to create an interactive "matrix" of interdependencies for the various applications used in their company (it's a travel&leisure company with around 2500 employees). The idea (still at the prototype stage) is to create a sort of Map, based on Visio or similar tool, which traces the communication and interdependencies between all the IT assets in the company, so that when someone asks for a change they can get an overview of the impacts. This was mentioned in a casual setting and it will not be my responsability to directly work on this, but I did contribute the little I know already in terms of vaguely related methodologies (Zachman Framework). I'd like to hear from the people in here if they know of methodologies, or tools, that may help this kind of effort, and if they have any specific experience to contribute. I'll digest the answers and send the result back to my customer, hoping this may be of some help with their task (which I consider a bit visionary and prone to all the pitfalls of any documentation project, but still well worth pursuing).

  • Wordpress Custom Themes > How to script Categories, Tags and Excerpt options to appear on "page" edi

    - by Scott B
    I'm using custom WordPress categories for some probably unintended functions, I will admit (things like marking a post no/index just by adding it to my custom "no-index" category, etc). But it sucks that WordPress does not enable pages with all the little extras you get with posts. For example, while the post editor gives you convenient access to Tags, Categories, and a Post excerpt field, pages get left out in the cold. I'd like to know if its possible to add the These items to the Post editor via add_action() directive from a custom theme.

  • Drupal Hierarchical Content

    - by Vecta
    I am currently looking at using either the Taxonomy or CCK module on my Drupal site as a means to create a hierarchical system. However, I'm a little confused on which one would best suit my needs, or if there is something else that would work better. Basically, there will be probably 70 or so "mini-sites" on the website I'm working on, each with a landing page and about 5 sub-pages of detailed information. I need a way to mark those sub-pages as being sub-pages of their parent page, as well as create a menu system to navigate between them. What is the best way this could be done? Thanks for your input!

  • Moving to OOP hopefully!

    - by Luke
    So I am trying to understand OOP more and use it. The following code was written before i started using OOP. //loop through all the users $game = "$_POST[Game]_teams"; $result = mysql_query("SELECT username FROM `users`") or die(mysql_error()); while( $row=mysql_fetch_assoc($result) ) { $u[] = $row['username']; } I have put the query into my database page like following: function selectAllUsers() { $q = "SELECT username FROM ".TBL_USERS.""; mysql_query($q, $this->connection); } I'm a little confused about how the rest could be different? Would it be? Is it possible for anyone to help me without more code or understanding of my structure?
