  • Add mask to input

    - by Lodewijk Wensveen
    I'm trying to achieve the seemingly impossible task of adding an mask to a input field. I have the following code: function addActivationCode(){ newRow = jQuery("div.activationcode:last-child").clone(); newRow.insertAfter(jQuery("div.activationcode:last-child")); newRow.attr("id", "coderow-" + Math.round(Math.random() * 10000)); newRow.find("input").val(""); find("input").mask("9999-9999-9999-9999"); newRow.find("a.coderemove").attr("onclick", "removeActivationCode('" + newRow.attr("id") + "'); return false;"); } function removeActivationCode(id){ jQuery("div#" + id).remove(); } Now I to get the .mask working on my input fields, so far I've only got it working on the new row I'm making and not on the original one. Can anyone help me out?

  • How to handle a C# console application terminating?

    - by Nick R
    If I have a console application, is there any way I can handle the following: Ctrl-C (I know the answer to this. Using Console.TreatControlCAsInput and Console.CancelKeyPress) Session termination, such as when someone logs off Process exit, such as when someone uses the task manager to close the application. I know that if I was writing a unix application, I would handle various signals to catch the request to close (SIGTERM from memory), but I also know I need to handle these messages pretty quickly and exit before the system does a kill -9 (SIGKILL). But for a C# console application, I'm not sure how to do this.

  • How to use DAOs with hibernate/jpa?

    - by Ari
    Assuming the DAO structure and component interaction described below, how should DAOs be used with persistence layers like hibernate and toplink? What methods should/shouldn't they contain? Would it be bad practice to move the code from the DAO directly to the service? For example, let's say that for every model we have a DAO (that may or may not implement a base interface) that looks something like the following: public class BasicDao<T> { public List<T> list() { ... } public <T> retrieve() { ... } public void save() { ... } public void delete() { ... } } Component interaction pattern is -- service DAO model

  • Turn RSS into array, explode the 'description' and insert words into MySQL table one per row

    - by K.I
    I have only recently gotten into php and MySQL and I want to take an RSS feed, turn it into an array, take only the description part of the XML, explode it and insert it into a table on a MySQL base. I feel like this should be possible, but is a little over my head right now. I tried using magpie as a parser, but if possible I want to do it in simpler php code. The result I am looking for would take a description "This is a cat" and insert it into a table with two fields ID term 1 This 2 is 3 a 4 cat I've been stumped on this for a couple days. Any help would be great.

  • How to make an existing socket fail?

    - by Huckphin
    OK. So, this is exactly the opposite of what everyone asks about in network programming. Usually, people ask how to make a broken socket work. I, on the other hand am looking for the opposite. I currently have sockets working fine, and want them to break to re-create this problem we are seeing. I am not sure how to go about intentionally making the socket fail by having a bad read. The trick is this: The socket needs to be a working, established connection, and then it must fail for whatever reason. I'm writing this in C and the drivers are running on a Linux system. The sockets are handled by a non-IP Level 3 protocol in Linux by a Linux Device Driver. I have full access to all of the code-base, I just need to find a way to tease it out so that it can fail. Any ideas?

  • oAuth provider with Django-piston

    - by Martin Eve
    Hi, I'm working with django-piston to attempt to create an API that supports oAuth. I started out using the tutorial at: http://blog.carduner.net/2010/01/26/django-piston-and-oauth/ I added a consumer to piston's admin interface with key and secret both set to "abcd" for test purposes. The urls are successfully wired-up and the oAuth provider is called. However, running my get request token tests with tripit (python get_request_token.py "http://127.0.0.1:8000/api" abcd abcd), I receive the following error: Invalid signature. Expected signature base string: GET&http%3A%2F%2F127.0.0.1%3A8000%2Fapi%2Foauth%2Frequest_token%2F&oauth_consumer_key%3Dabcd%26oauth_nonce%3D0c0bdded5b1afb8eddf94f7ccc672658%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1275135410%26oauth_version%3D1.0 The problem seems to lie inside the _check_signature method of Piston's oauth.py, where valid_sig = signature_method.check_signature(oauth_request, consumer, token, signature) is returning false. I can't, however, work out how to get the signature validated. Any ideas?

  • I don't understand how to use delegates in Cocoa but I know what they are.

    - by lampShade
    Like many people I'm interested on Objective - C and Cocoa programming. I know conceptually what a delegate it is but I don't understand how to use them or when to use them. Here is some example code: #import "AppControler.h" @implementation AppControler -(id)init { [super init]; NSLog(@"init"); speechSynth = [[NSSpeechSynthesizer alloc] initWithVoice:nil]; // [speechSynth setDelegate:self]; voiceList = [[/Applications/Google Chrome.app availableVoices] retain]; return self; } I'm setting the AppControler to be the delegate of the speechSynthasizer. Which means that the speechSynthasizer is telling hte AppControler what to do. But I don't understand this line: [speechSynth setDelegate:self];

  • Best language to learn complementing java

    - by danielrutledge
    Hi all, I'm a somewhat experienced java ee developer, and I wish to complement my background by learning a newish language. I'm recently out of school where I did a ton of scientific computing and some functional programming, so I'm pretty comfortable with those families of languages. If at all possible, I'd like to pick a language with some market value, though I know this is tough to gauge. After snooping around a bit, the consensus seems to be one of Python/Ruby/Perl; how would each of these work with java in a web application environment, and in your opinion which complements it best? Any other suggestions for languages would also be welcome.

  • Advanced Java book in the lines of CLR via c# or C# in Depth?

    - by devoured elysium
    I want to learn about how things work in depth in Java. Coming from a c# background, there were a couple of very good books that go really deep in c# (C# in depth, CLR via c#, just to name the most popular). Is there anything like that in Java? I searched it up on amazon but nothing seemed to go that deep in Java as the two above go in c#. I don't want to know more about specific classes, or how to use this library or that other library, I want to learn how the objects are created on memory, how they get created on the stack, heap, etc. A more fundamental knowledge, let's say. I've read some chapters of Effective Java and The Java Programming Language but they don't seem to go so deep as I'd want them to go. Maybe there are other people that know both c# and Java that have read any of the referred books and know any that might be useful? Thanks

  • PHP New Line Help

    - by Jeremy Person
    I'm just starting PHP programming as you can tell. I want the results of each statement to be on their own line but can't get it to work yet. I tried referring to the code on this page and am obvsiously doing something wrong. Thank you very much. <? $mySentence="This is a sentence 123456789."; $myNumber1 = 9.5; $myNumber2 = .5; $sum = $myNumber1 + $myNumber2; echo "Hello, lets display our PHP variables: \r"; echo $mySentence; echo "The sum of $myNumber 1 and $myNumber2 = $sum "; echo "\"This text has double quotes\""; ?>

  • Convert doc/docx to semantic HTML

    - by sandstrom
    I would like to convert doc/docx documents to semantic HTML. Some wishes/requirements: Semantic HTML such that headers in the document are <h1>, <h2> etc., tables are <table> and so forth. Should preferably be possible to handle headings, lists, tables and images. Graphs and math formulas is a nice extra. • Doesn't have to be converted straight from doc/docx to html, could use an intermediary format, such as xml or docbook. • Should work programatically, and with large number of documents. The closest thing to a solution I've found so far is http://holloway.co.nz/docvert/index.html, but unfortunately there are many a few bugs, small user base and it can't handle a lot of documents. More of a proof of concept.

  • Intellij-Idea: Marking all files of unknown type as text (so that they are searchable)

    - by sixtyfootersdude
    Many of my scripts etc in intellij are marked with a question mark. Then when I click on them them it prompts me: The file "bla" cannot be associated with a registered file type. Please choose one: <insert table of file choices> This would not matter except the files are not searchable (with ctrl-shift-n) until they are marked as text. This is a major problem for me. I have an enormous code base and I don't want to mark all of the unknown files as text. Is there anyway that I can do that?

  • Frame.Navigate to an embedded resource F#

    - by akaphenom
    I have a 100% silverlight 3.0 / f# 2.0 application I am wrapping my brain around. I have the base application loading correctly - and now I want to add the naigation controls to it. My page is stored as an embedded resource - but the Frame.Navigate takes a URI. I know what I have is wrong but here it is: let nav : Frame = mainGrid ? mainFrame let url = "/page1.xaml" let uri = new System.Uri(url, System.UriKind.Relative) ; nav.Navigate uri Any thoughts?

  • Using C# and VB.NET in one solution

    - by Younes
    I'm busy on a small project to convert an Access2003 db to .NET. I am trying to integrate my functionality in an excisting project that is being used for Administration of some kind. The code in this project is vb.net. I started by setting up my Data Access Layer, which seems to work fine. I can make new web pages that acces the data I need. However when i start to use class files to set up my Business Logic Layer i can't build my project when using C# instead of VB. I Dislike VB and like to program in C# as i know the syntax alot better etc. Is it possible to program using C# knowing that VB.NET was the language chosen to buold the entire project on? If not, what will be the smartest way to integrate my module into the project using my favorite programming language? (Make a project and reference to the dll?)

  • Are there any widespread, modern Java coding conventions?

    - by brianegge
    Sun's "Code Conventions for the Java Programming Language" was last updated April 1999. Ten years later a lot has changed in the language, as well as general usage patterns. Are there more up to date, widely adopted standards? Most guidelines omit specifying file encoding and line endings. Sun recommends mixed tabs and spaces. The Eclipse IDE defaults to Eclipse's standard, which is tabs only. The Maven style guide is spaces only. Many style guides, such as JBoss, follow Sun's guidelines, but prefer K&R braces instead of OTBS. Each Apache project has it's own style guide, with slight differences between each one.

  • Equality and Assigment Operators

    - by Jeremy Smith
    I have a assembly compiled in VB.NET that contains two operators: Public Shared Operator =(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return quarterA.StartDate = quarterB.StartDate AndAlso quarterA.EndDate = quarterB.EndDate AndAlso quarterA.Quarter = quarterB.Quarter End Operator Public Shared Operator <>(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return Not (quarterA = quarterB) End Operator However, when using the assembly in C# to perform equality checks if (qtr != null) I receive the error: Cannot implicity convert type 'object' to 'bool' My original intent with the = operator was only for assignment purposes in VB, so I may be way off base (I don't use custom operators too often). What do I need to do to make the operator behave with both equality and assignment operations?

  • Terminate long running thread in thread pool that was created using QueueUserWorkItem(win 32/nt5).

    - by Jake
    I am programming in a win32 nt5 environment. I have a function that is going to be called many times. Each call is atomic. I would like to use QueueUserWorkItem to take advantage of multicore processors. The problem I am having is I only want to give the function 3 seconds to complete. If it has not completed in 3 seconds I want to terminate the thread. Currently I am doing something like this: HANDLE newThreadFuncCall= CreateThread(NULL,0,funcCall,&func_params,0,NULL); DWORD result = WaitForSingleObject(newThreadFuncCall, 3000); if(result == WAIT_TIMEOUT) { TerminateThread(newThreadFuncCall,WAIT_TIMEOUT); } I just spawn a single thread and wait for 3 seconds or it to complete. Is there anyway to do something similar to but using QueueUserWorkItem to queue up the work? Thanks!

  • Advanced Rails Routing of short URL's and usernames off of root url

    - by Michael Waxman
    I want to have username URL's and Base 58 short URL's to resources both off of the root url like this: http://mydomain.com/username #=> goes to given user http://mydomain.com/a3x9 #=> goes to given story I am aware of the possibilities of a user names conflicting with short urls, and I have a workaround, but what I can't figure out is the best way to set this up in rails. Can I do it in rails routes? Should I do something with a piece of Rack middleware? Should I set up a routing controller? Please let me know the best way to do this. Thanks so much!

  • Choosing a source control system: logical next steps after VSS

    - by Dave
    I've been using Git for the past few months and love it. I looked into how to host it in a corporate environment. Considering a 10 person team who use Visual SourceSafe, programming in Coldfusion, Powerbuilder, PHP and a bit of .NET, I found, to my surprise, that the Git 'server' tooling is still fairly rudimentary. http://stackoverflow.com/questions/1761054/git-in-a-company-hosting-own-server Question Apart from SVN, what other source control options would be a logical next step after VSS? Paid options are fine. Something with nice tooling, that isn't scary would be great :-)

  • Why is IHttpAsyncHandler being called over IHttpHandler?

    - by Tim Hardy
    I made a custom handler that derives from MvcHandler. I have my routes using a custom RouteHandler that returns my new handler for GetHttpHandler(), and I override ProcessRequest() in my custom handler. The call to GetHttpHandler is triggering a breakpoint and my handler's constructor is definitely being called, but BeginProcessRequest() is being called on the base MvcHandler instead of ProcessRequest(). Why are the async methods being called when I haven't done anything to call them? I don't want asynchronous handling, and I certainly didn't do anything explicit to get it. My controllers all derive from Controller, not AsyncController. I don't have the source code with me right now, but I can add it later if needed. I was hoping someone might know some of the reasons why BeginProcessRequest might be called when it's not wanted.

  • Step-by-step execution for Intel AT&T assembler?

    - by Søren Haagerup
    Hello everyone, I'm writing a compiler that converts source code (written in a small imperative programming language) to Intel AT&T 32-bit assembler. I tend to spend a lot of time debugging, because of nasty offset-mistakes etc. in the generated code, and I would like to know if anyone knows of a tool to "walk through" the generated assembler code step-by-step, visualizing what's on the stack etc. I use Ubuntu Linux as my development platform, and I'm comfortable with the terminal -- a GUI-program would be nice though. Does it exist? Or is there a good reason it doesn't (maybe the problem isn't so straightforward..?) If you have good ideas for approaching debugging tasks in assembly code, I'll be glad to hear from you!

  • ASP.NET MVC 2 RC 2 returns Area-specific controller when no area specified

    - by Bryan
    I have a basic MVC 2 (RC2) site with one base-level controller ("Home"), and one area ("Admin") with one controller ("Abstract"). When i call http://website/Abstract - the Abstract controller in the Admin area gets called even though i haven't specified the Area in the URL. To make matters worse - it doesn't seem to know it's under Admin because it can't find the associated view and just returns: The view 'Index' or its master was not found. The following locations were searched: ~/Views/Abstract/Index.aspx ~/Views/Abstract/Index.ascx ~/Views/Shared/Index.aspx ~/Views/Shared/Index.ascx Am i doing something wrong? Is this a bug? A feature?

  • Naive Bayesian for Topic detection using "Bag of Words" approach

    - by AlgoMan
    I am trying to implement a naive bayseian approach to find the topic of a given document or stream of words. Is there are Naive Bayesian approach that i might be able to look up for this ? Also, i am trying to improve my dictionary as i go along. Initially, i have a bunch of words that map to a topics (hard-coded). Depending on the occurrence of the words other than the ones that are already mapped. And depending on the occurrences of these words i want to add them to the mappings, hence improving and learning about new words that map to topic. And also changing the probabilities of words. How should i go about doing this ? Is my approach the right one ? Which programming language would be best suited for the implementation ?

  • Why is my NSMutableArray returning nill?

    - by lampShade
    I have a very simple task: add the contents of a textField to an NSMutableArray.The Problem is the array is returning nill. I believe that it has something to do with the fact that the array I'm using is declared as an instance variable. /* IBOutlet NSTextField *textField; IBOutlet NSTabView *tableView; IBOutlet NSButton *button; NSMutableArray *myArray; */ #import "AppController.h" @implementation AppController -(IBAction)addNewItem:(id)sender { NSString *string = [textField stringValue]; NSLog(@"%@",string); [myArray addObject:string]; NSLog(@"%d",[myArray count]);//this outputs 0 why is that? }

  • Substring and its reverse in a string

    - by christa
    My professor was talking about this in a Dynamic programming class and asked us to think over it. She gave us some examples as well. Given a string, we were to find the longest continuous subsequence whose reverse is also a subsequence present in the given string. Example: INPUT: pqrstuvtsrv OUTPUT: i=3, k=2 rst -> tsr (rst found first at i=3 and for 2 more positions) INPUT: mpqrsrqp OUTPUT: i=2, k=6 pqrsrqp in reverse INPUT: mmpqssss OUTPUT: i=5, k=3 I thought of putting the string and its reverse into 2 different arrays and comparing character by character. But I'm sure this is not the best way to do it. Any suggestions as to what could be the most efficient ?
