  • Does JSLint parse DOM functions?

    - by Paul
    I tried to use the parse() function of JSLint to parse three pieces of JavaScript code: function(b, c){var a = b + c; return a; } window.addEventListener('click', click_hanlder, true); document.documentElement.innerHTML; Here's the code, which is copied and pasted from the JSLint self-parse example: ` try { parse = make_parse(); var source = "something to parse";//replaced by the code above tree = parse(source); if (tree) { document.write(JSON.stringify(tree, ['key', 'name', 'message', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } } catch (e) { document.write(JSON.stringify(e, ['name', 'message', 'from', 'to', 'key', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } ` The output: returns a correct tree. returns a tree with only one node of "window". crashes the browser. I'm wondering whether JSLint doesn't support DOM function.

  • Why hasn't anybody started a hosted continuous integration service?

    - by Teflon Ted
    There's a dozen services that provide hosted version control, hosted ticket tracking, hosted project management, and combinations of all of the above, there's even hosted web-based IDEs. But nobody's yet offered a hosted continuous integration service; at least that I can find. The concept seems simple enough: I register and provide the URL to my source code repository, it grabs my code and builds it via ant/rake/whatever, then runs the suite of tests and some metrics (code coverage, performance, etc.). Is there some prohibitive barrier to entry I'm not considering?

  • Easy to use/learn PHP framework?

    - by Meredith
    I need to build a php app, and I was thinking about using a framework (never used one before). I've been browsing around some but most of them seems kinda complicated, I really liked what I saw about Symfony, but it looks like I will have to spend like a month until I really understand how to use it, and in one month I could code the app I have in mind 5 times without a framework. But I want to use one to "standardize" my code and prevent bugs. So I was wondering if someone could share with me which php frameworks you think are easier to learn how to use. My application will use mysql, and it will have some sort of "search engine" to search data that will be populated on the database using a few "scraper scripts" (that I also wants to code using the framework).

  • Hide Segemented Control on NavBar, then add Title

    - by Jordan Clark
    Basically I have a Segmented Controller on my NavBar right in the middle. What I want to be able to do is hide the Segmented Controller and add a title to the navigation bar. But with my code, the segmented controller is being hidden, but the title will not add, thus leaving a blank NavBar. This is my simple code in .h: IBOutlet UISegmentedControl *toggleDay; IBOutlet UINavigationBar *navBar; And this is my code in my .m: toggleDay.hidden = YES; navBar.topItem.title = @"Title"; Any help would be great thanks!

  • Serving large generated files using Google App Engine?

    - by John Carter
    Hiya, Presently I have a GAE app that does some offline processing (backs up a user's data), and generates a file that's somewhere in the neighbourhood of 10 - 100 MB. I'm not sure of the best way to serve this file to the user. The two options I'm considering are: Adding some code to the offline processing code that 'spoofs' it as a form upload to the blob store, and going thru the normal blobstore process to serve the file. Having the offline processing code store the file somewhere off of GAE, and serving it from there. Is there a much better approach I'm overlooking? I'm guessing this is functionality that isn't well suited to GAE. I had thought of storing in the datastore as db.Text or Dd.Blob but there I encounter the 1 MB limit. Any input would be appreciated,

  • Error handling and polymorphism

    - by Neeraj
    I have an application with some bunch of code like this: errCode = callMainSystem(); switch (errCode){ case FailErr: error("Err corresponding to val1\n"); case IgnoreErr: error("Err corresponding to val2\n"); ... ... default: error("Unknown error\n"); } The values are enum constants. Will it make some sense to have something like: // Error* callMainSystem() ... Some code return FaileErr(); // or some other error // handling code Error* err = callMainSystem(); err->toString(); The Error class may be made singleton as it only has to print error messages. What are the pros and cons of above methods,size is an important criteria as the application needs to be supported on embedded devices as well. P.S: I don't want to use exception handling because of portability issues and associated overheads.

  • WPF: Convert memory stream to BitmapImage?

    - by David Veeneman
    I have an image that was originally a PNG that I have converted to a byte[] and saved in a database. Originally, I simply read the PNG into a memory stream and converted the stream into a byte[]. Now I want to read the byte[] back and convert it to a BitmapImage, so that I can bind a WPF Image control to it. I am seeing a lot of contradictory and confusing code online to accomplish the task of converting a byte[] to a BitmapImage. I am not sure whether I need to add any code due to the fact that the image was originally a PNG. Can anyone provide the code to convert the stream to a BitmapImage? Thanks for your help.

  • European signs in img src problem

    - by Rakoon
    Hey. I recently encountered a strange problem on my website. Images with æ ø and å in them (Western European signs) Won't display. The character encoding on all sites is "Iso-8859-1" I can print æ ø and å on the page without problems. If I right click the "broken image" and choose properties, it displays the filename with the european signs. (/admin/content/galleri/å.jpg) the code for img looks like this <img name='bilde' src='content/{$_SESSION["linkname"]}/{$row["img"]}' class='topmargin_ss leftmargin_ms rightmargin_s' width='80' height='80'> (Wasn't allowed to post images so the code is without starting and ending brackets) Made 4 files: z.jpg æ.jpg ø.jpg å.jpg Only z.jpg shows up, they are the exact same jpg. The images are uploaded using php code, which works, uploads to the right directory and has no problem with the european signs. Does anybody know what could be causing this?

  • Assigning a previous fieldvalue to a field in the next record

    - by user2945849
    I am working on a loan amortization schedule using Access, I have created the following tables: tblMembers - autoMemberID|txtLN|txtFN|etc tblLoans - autoLoanID|numMemberID|etc tblSchedules -autoScheduleID|numLoanID|numPayment#|datDue|dblBegin|...|dblEnd tblPayments - autoPaymID|numLoanID|curAmtPaid|datPaidDate and forms: frmLoans - autoLoanID|etc sbfSchedules - numPaymID|datDue|dblBegin|...|dblEnd sbfPayments - dblAmount|datPaid I have been able to generate the schedule (using DAO recordset) clicking a btnRepaymentSchedule the challenge is when I click a btnAddPayment still on the sbfSchedules, I want the value of the dblEnd field to be the value of the next record dblBegin field! I have tried using dlookup(txtBeginBalance = Dlookup("EndBalance", _ "Schedules","[ScheduleID] = Form![Schedules]![ScheduleID]-1) but there is no effect but if I use txtBeginBalance = txtEndBalance the value of txtEndBalance is assigned to the value of txtBeginBalance of the same record (want next record). Secondly, how can I set focus to the next record if a contro(txtAmountPaid) is not null on clicking the btnAddPayment or assigning the value of a calculation when the control is 0 or null ? Thanks

  • ASP.NET Long Process and Sending updates to Browser

    - by user204588
    Hello, I've asked this before but I was hoping for another answer and perhaps some code samples because I've been having a difficult time with this. I have an asp.net page. The user hits the "Run" button and I have code IN AN ASSEMBLY, not in the APP_CODE folder that is called and runs a long process that moves product info from a file into the database. While the user waits, I would like them to see status updates like what product the import process in on and status info. I'm assuming I'd break off into another thread and use Ajax but I have no idea how to do this. Some code samples would be very helpful, thanks.

  • How to generate multiple Alter Scripts in SSMS

    - by dannyRods
    I'm using sql server management studio 2008 to try and generate an alter script for each of my stored procedures in order to save the scripts for each revision. I can easily generate an alter script for each individual procedure, but I'm not trying to go through a hundred stored procedures manually. I know that SSMS has an automated generate scripts function under task, but the only options are create, drop and create, and drop. I cant seem to figure out how to enable alter. I've already searched through many SO articles, as well as a little digging in msdn, and I've come up with nothing. I'm hoping that the fine people of stackoverflow will be up to the challenge. Thanks in advance

  • hadoop mapper static initialisation

    - by rakeshr
    Hi, I have a code fragment in which I am using a static code block to initialize a variable. public static class JoinMap extends Mapper<IntWritable, MbrWritable, LongWritable, IntWritable> { ....... public static RTree rt = null; static { String rtreeFileName = "R.rtree"; rt = new RTree(rtreeFileName); } public void map(IntWritable key, MbrWritable mbr,Context context) throws IOException, InterruptedException { ......... List elements = rt.overlaps(mbr.getRect()); ....... } } My problem is that the variable rt in the above code fragment is not getting initialised. Can anybody suggest a fix or an alternate way to initialise the variable. I don't want to initialise it inside my map function since that slows down the entire process.

  • jQuery DataLink - Does DataLink solve my use case?

    - by AnApprentice
    Hello, I recently heard of the jQuery datalink plugin and wondered if I should be using if for the following: I have a an inbox in my app that consists of the following: Inbox (index) - List of Items (list of mails) Inbox (show) Item Viewer (1 mail) Inbox Unread Counter The challenge I'm having now is a user can mark a mail as read/unread in either view which makes keeping the counter accurate challenging. Can datalink help with this? If so how? Also, I read that datalink requires forms is that true? Or can I bind the links to anything like 0 and anytime a mailitem changes from read to unread it would automatically update? Thanks

  • Why wouldn't I be able to establish a trust relationship for a SSL/TLS channel?

    - by Abe Miessler
    I have a piece of .NET code that is erroring out when it makes a call to HTTPWebRequest.GetRequestStream. Here is the error message: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. I've read a few things that suggest that I might need a certificate on the machine running the code, but i'm not sure if that's true or how to do it. If I need to get a certificate, how do I do it? Code: var request = (HttpWebRequest)HttpWebRequest.Create(requestUrl); //my url request.Method = StringUtilities.ConvertToString(httpMethod); // Set the http method GET, POST, etc. if (postData != null) { request.ContentLength = postData.Length; request.ContentType = contentType; using (var dataStream = request.GetRequestStream()) { dataStream.Write(postData, 0, postData.Length); } }

  • IE is not loading all images

    - by newbie
    I have jQuery code that loads images with jQuery load method. It works perfectly in all other browsers, except in IE. I have about 10 images, but IE only loads few of those images and then stops loading. What could be causing this? $(".image-container").each(function() { ... some code here ... var img = $("img", this); $(img).load(function () { ... some code here ... }); });

  • Python: confused with classes, attributes and methods in OOP

    - by user1586038
    A. Am learning Python OOP now and confused with somethings in the code below. Question: 1. def init(self, radius=1): What does the argument/attribute "radius = 1" mean exactly? Why isn't it just called "radius"? The method area() has no argument/attribute "radius". Where does it get its "radius" from in the code? How does it know that the radius is 5? """ class Circle: pi = 3.141592 def __init__(self, radius=1): self.radius = radius def area(self): return self.radius * self.radius * Circle.pi def setRadius(self, radius): self.radius = radius def getRadius(self): return self.radius c = Circle() c.setRadius(5) """ B. Question: In the code below, why is the attribute/argument "name" missing in the brackets? Why was is not written like this: def init(self, name) and def getName(self, name)? """ class Methods: def init(self): self.name = 'Methods' def getName(self): return self.name """

  • The remote server returned an error: (407) Proxy Authentication Required

    - by chris
    I'm getting this error when I call a web service: "The remote server returned an error: (407) Proxy Authentication Required". I get the general idea and I can get the code to work by adding myProxy.Credentials= NetworkCredential("user", "password", "domain"); or by using DefaultCredentials in code. My problem is that the call to the web service works in production without this. It seems like there is a non code solution involving Machine.config, but what is it? At the moment I can't get to the production boxes machine.config file to see what that looks like. I tried updating my machine.config as follows, but I still get the 407 error.

  • Help modifying QuartzDemo example application

    - by BittenApple
    Can anyone please, oh sweet pain, please take me out of my misery by writing a simple example on how the heck you pass a number (int value) which gets created in 1 .m file to another .m file. In the apple demo application called QuartzDemo, there is a file called QuartzImages.m This file has the following line of code: [CODE]CGPDFPageRef page = CGPDFDocumentGetPage(pdf, 1);[/CODE] Notice the (pdf, 1) in that line. This number should be replaced with an integer variable. Now, there is also a file called MainViewController.m. In that file, there is a method? called -(void)viewDidLoad In that method, I want to assign a number to the integer variable which would replace the damn "1" with whatever number I want. I have been pulling my hair trying to get this done, reading beginning iPhone 3 Development book, dev documentation and God knows what not, without results. Any help would be greatly appreciated... Sigh.

  • Can I detect unused extra parameters passed to javascript methods?

    - by Pablojim
    In Javascript I can call any method with more than the necessary amount of parameters and the extra parameters are silently ignored. e.g. letters = ['a','b','c'] //correct letters.indexOf('a') //This also works without error or warning letters.indexOf('a', "blah", "ignore me", 38) Are there ways to detect cases where this occurs? My motivation is that in my experience cases where this occurs are usually bugs. Identification of these by code analysis or at runtime would help track these errors down. These cases are especially prevalent where people are expecting alterations to base types which may not have occurred. Logging a warning where this happens e.g. Date.parse('02--12--2012', 'dd--MM--YYYY') Notes: To be clear I would like a solution that doesn't involve me sprinkling checks all over my code and other peoples' code.

  • Looking for substantial open source GWT/App-Engine project to use as reference

    - by tempy
    I'm working on GAE-J/GWT app, wherein a desktop app connects to the GAE-J component, and there is also a web-app component whose front-end is written in GWT, and the GAE-J backend supports both the desktop app and the web app. I have a good amount of experience with writing pure server code and desktop code, but not so much on the web-app side of things. So I'm looking to study some good sophisticated open source code to see how other's have done things, but I can't find much open source GWT and/or GAE-J stuff, other than frameworks. Does anyone know of any good projects out there?

  • Array.Copy: strange exception while concatenating two byte arrays

    - by robob
    In a application of mine that is developed in C# I have the following code: byte[] resb = new byte[Buffer.ByteLength(blockAr) + Buffer.ByteLength(previous)]; Array.Copy(blockAr, 0, resb,0, blockAr.Length); Array.Copy(previous, 0, resb, blockAr.Length, previous.Length); It's a very simple code to concatenate two byte arrays. The problem is that in some particular situation that I don't know I have that exception: ArgumentOutOfRangeException: sourceIndex is less than the lower bound of the first dimension of sourceArray. I cannot see any of strange in my code and I am not able to reproduce the exception. Could anyone help me to identify the problem? thanks

I am trying the format like: This is the simple text And I am [b] bold text[/b].

And What is the right method to parse this kind of post? Shall I use regular expression to parse this or there is another standard for this. If the above mentioned format is not the right way for storage, then what it could be? Thanks

  • What are some good ways to promote my Android application?

    - by Bryan Denny
    I'm a new Android developer and I just released a free, open source tipping calculator app called Tippy Tipper. I created this app to get myself familiar with Android and to hopefully provide a good example app for other new developers to look at. Now that I've overcome the challenges of learning how to program, test and release my Android app, I've come across a new challenge: marketing! What are some good ways to promote my app to the Android community? Can anyone with some experience talk about how they did this successfully with their own app?
