  • Guide Text Not working when text is entered using another control

    - by user2614405
    I have a textbox used to enter the text by user, which guide-text which disappears when user starts to write. But when I use a dropdown & select a text from it, & this text is automatically entered in the textbox, the guide-text is not fading away. Events I am using to fade the guide-text : $('input, textarea').live('keydown', toggleLabel); $('input, textarea').live('paste', toggleLabel); On change of dropdown : $('.ui-discussion-text').change(function () { var oldText = $('.ui-discussion-input textarea').val(); $('.ui-discussion-input textarea').val(oldText + " " + $(this).val()); }); Please help.

  • better for-loop syntax for detecting empty sequences?

    - by Dmitry Beransky
    Hi, Is there a better way to write the following: row_counter = 0 for item in iterable_sequence: # do stuff with the item counter += 1 if not row_counter: # handle the empty-sequence-case Please keep in mind that I can't use len(iterable_sequence) because 1) not all sequences have known lengths; 2) in some cases calling len() may trigger loading of the sequence's items into memory (as the case would be with sql query results). The reason I ask is that I'm simply curious if there is a way to make above more concise and idiomatic. What I'm looking for is along the lines of: for item in sequence: #process item *else*: #handle the empty sequence case (assuming "else" here worked only on empty sequences, which I know it doesn't)

  • Does Ruby/Rails require more unit testing than say a PHP app?

    - by Blankman
    I don't find the unit testing push in the PHP market like I see/read in the ruby/rails arena. Could one just as easily NOT unit test in ruby/rails as in php, or is ruby just too bendable and breakable that it "more" recommended to test in ruby than in php? Meaning there are large code bases like vBulletin, and from what I can tell, they don't unit test. I hope you understand what I am asking here, not the pros/cons of testing, or whether one should test or not, but rather, does one language need to be tested more than another? maybe its easy to write buggy code, or break during refactoring etc.

  • iPhone UIImage Display Controller

    - by Bill Shiff
    Hello, I would like to be able to display a UIImage from within my app and support a lot of the functionality available in the built-in Photos app (i.e., pinch-to-zoom, pan, etc). I don't really want to write a bunch of code that someone has already written, so I'm wondering if there is a library out there already that I could just import into my project. I'm aware of the Three20 project, but I don't want to import a huge library if I don't have to. Is anyone aware of an available library that's already out there for displaying UIImages? Or part of some open-source project that can be pulled out on its own? Thanks!

  • Simple modal div in jQuery?

    - by jasondavis
    I have tried almost all of the jQuery Modal plkugins I can find on the net but they are all much to bulky for what I need. I dont need all the fancy features, I want to be able to open a div and have the background of the page go transparent grey like the photo below and have my div be on top of it, that is all I need to do so I would like to write some jquery to do this instead of using a bulky plugin. Does anyone have any small code that can do this task? Is the transparent background an image or just css?

  • Is there any advantage to having more than 16gb ram on a Windows Dev machine?

    - by Robert Kozak
    Assuming a machine (Dual Quad Core Xeon (2.26GHz) with 24GB RAM) running Windows Server 2008 and Hyper-V. How many VMs can I expect to run at the same time with good performance. Is this overkill? Can you really have too much RAM? Assuming 2GB per VM thats around 16GB for the VMs with 8GB left over for the Main OS and Hyper-V. Sound about right? Edit: Tried to make the question sound less like bragging. Was never my intention. Its a hard question to write.

  • What is a good reporting service for a simple database/hobbyist setup?

    - by Zombies
    I have a meager production environment running on my PC for a little application that I work on in my spare time. At this point I have the basics setup, MySQL, junit, svn... I am midway through development and I now need to generate various reports. These reports are based on what data is in the database.... Now, my question is this: Is there an existing reporting tool that accepts SQL and generates various reports (via: email, PDF, etc). Some tool which makes writing new reports easy, while also having a somewhat robust set of features. Does this software exist or must I write all of these reports myself?

  • To not iterate through function of Array object if it is added to Array prototype

    - by Rishat Muhametshin
    According to the way to add indexOf method to Array class in IE6, how do I now reject this method from iterating through any random array? For example: Array.prototype.indexOf = function(needle) { ... }; var array = [1, 2, 3]; for (var i in array) { document.write(i + ': ' + array[i]); } gives output 0: 1 1: 2 2: 3 indexOf: function ... How can I skip indexOf property and stop iterating on it without adding any code to where for(...) is called?

  • Writing Lucene StandardAnalyzer results to text file with OutputStreamWriter

    - by user3693192
    I'm getting ONLY the last result written to "outputStreamFile.txt". Can't figure out how to revise code so I can get ALL results written to text file. Sample input text: "1st line of text\n" "2nd line of text \n" Results in only 2nd line begin written (and not 1st line) as: "2nd line text\n" private static void analyze(String text) throws IOException { analyzer = new StandardAnalyzer(Version.LUCENE_30); Reader r = new StringReader(text); TokenStream ts = (TokenStream) analyzer.tokenStream("", r); TermAttribute term = ts.addAttribute(TermAttribute.class); File outfile = new File("C:\\Users\\Desktop\\outputStreamFile.txt"); FileOutputStream fileOutputStream = new FileOutputStream(outfile); OutputStreamWriter outputStreamWriter = new OutputStreamWriter(fileOutputStream, "UTF8"); while(ts.incrementToken()) { //System.out.print(term.term() + " "); outputStreamWriter.write(term.term().toString() + "\r\n"); } outputStreamWriter.close(); }

  • Reverse engineering a custom data file

    - by kerchingo
    At my place of work we have a legacy document management system that for various reasons is now unsupported by the developers. I have been asked to look into extracting the documents contained in this system to eventually be imported into a new 3rd party system. From tracing and process monitoring I have determined that the document images (mainly tiff files) are stored in a number of 1.5GB files. These files seem to be read from a specific offset and then written to a tmp file that is then served via a web app to the client, and then deleted. I guess I am looking for suggestions as to how I can inspect these large files that contain the tiff images, and eventually extract and write them to individual files.

  • Are there any good books on writing commercial quality software?

    - by Andy
    Hey, My background has been generally new technology demonstrators, which, well... demonstrate the latest technology and how it can be of use to a clients company. They use it for internal demos etc. Now my career has shiffed course a bit more into actual products, in particular software which runs in locations like museums as interactive pieces. Clearly, although the technology demonstrators had to be well coded etc, there wasn't as much emphasis as there is on my current work, which has to work, be highly configurable, probably multi-ligual and run constantly, without restarts. So my question is, now that I'm trying to up my coding quality and write more commercial applications, are there any books which discuss issues surrounding high quality commercial software? I currently have a copy of Code Complete 2nd Edition, which is excellent, but just wondering if there's any better, possibly more focused titles out there? Thanks a lot! Andy.

  • .NET platform independant sync framework

    - by Quandary
    Question: I need to synchronize a few ActionScript files from my computer to a network share (backup). I saw a quick fix would be using Microsoft Sync Framework for this, and write a windows service. My problem is I also use Linux, and before I start with MS vendor lockin, is there any sync framework/library/whatever I could use that works accross platform? Or does the MS sync framework work on Linux, too? It is my understanding that it is a wrapper around some com objects, thus it wouldn't work. All I need is synchronizing files. So never mind the database part, although it would be nice to have it, too.

  • Getting every nth Element of a Sequence

    - by Alexander Rautenberg
    I am looking for a way to create a sequence consisting of every nth element of another sequence, but don't seem to find a way to do that in an elegant way. I can of course hack something, but I wonder if there is a library function that I'm not seeing. The sequence functions whose names end in -i seem to be quite good for the purpose of figuring out when an element is the nth one or (multiple of n)th one, but I can only see iteri and mapi, none of which really lends itself to the task. Example: let someseq = [1;2;3;4;5;6] let partial = Seq.magicfunction 3 someseq Then partial should be [3;6]. Is there anything like it out there? Edit: If I am not quite as ambitious and allow for the n to be constant/known, then I've just found that the following should work: let rec thirds lst = match lst with | (_,_,x)::t -> x::thirds t | _ -> [] Would there be a way to write this shorter?

  • Creating an Application to Save Arbitrary Application State

    - by ashes999
    See this SuperUser question. To summarize, VM software lets you save state of arbitrary applications (by saving the whole VM image). Would it be possible to write some software for Windows that allows you to save and reload arbitrary application state? If so (and presumably so), what would it entail? I would be looking to implement this, if possible, in a high-level language like C#. I presume if I used something else, I would need to dump memory registers (or maybe dump the entire application memory block) to a file somewhere and load it back somewhere to refresh state. So how do I build this thing?

  • Generate a pdf thumbnail (open source/free)

    - by AndrewB
    Looking at other posts for this could not find an adequate solution that for my needs. Trying to just get the first page of a pdf document as a thumbnail. This is to be run as a server application so would not want to write out a pdf document to file to then call a third application that reads the pdf to generate the image on disk. doc = new PDFdocument("some.pdf"); page = doc.page(1); Image image = page.image; Thanks.

  • T4 Template Interception

    - by JeffN825
    I'm wondering if anyone out there knows of any T4 template based method interception systems? We are beginning to write mobile applications (currently with MonoTouch for IOS). We have a very nice core set of DI/IoC functionality and I'd like to leverage this in development for the new platform. Since runtime code generation Reflection.Emit is not supported, I'm hoping to use T4 templates to implement the dynamic interception functionality (+ TinyIoC as a container for resolution). We are currently using Castle Windsor (and intend to continue doing so for our SL and full .NET development), but all of the Windsor specific ties are completely encapsulated, so given a suitable T4 solution, it shouldn't be hard to implement an adapter that uses a T4 based implementation instead of Windsor.

  • How to encode 'á' to '&#225' with C# ?? (UTF8)

    - by Llorens Marti
    Hi all I'm trying to write an XML file with UTF-8 encode, and the original string can have invalid characters like 'á', so, i need to change these invalid characters to a valid ones. I know that there is an encoding method that take, for example, character 'á' and transform it to group of characters 'á'. I am trying to achive this with C#but i have no succes on it. I am using Encoding.UTF8 functions but i only end with the sema character (i.e: á) or a '?' character. So, do you know with is the correct way to achive this character change with C# ?? Thanks for your time and help :) LLORENS

  • Javascript/jQuery: Varying parameters on a custom function

    - by dclowd9901
    I'm writing a plugin that will allow parameters to 'set it up.' But I predict the user won't always want to set up every aspect of the function. function This_Function(a,b,c,d); For instance, maybe they'll only want to set up a and c, but not b and d (they'll just prefer to leave those as defaults). How do I write the function (or the parameters for that matter) so that the user can customize which functions they would prefer to pass? I have a feeling it involves parsing input, but I've seen many other functions with this capability. Thanks in advance for the help.

  • Is there a way to serialize automatically enums as int?

    - by FireAphis
    Hello, Is there a way to serialize enums automatically as int? Every time I define a new enum and write std::stringstream stream; stream << myenum1; stream >> myenum2; the compiler complains that the operators << and are not defined. Do you know a way to tell the compiler to treat enums as plain int's? What makes the problem harder is that, actually, the serialization is inside a template. Something like this: template <typename T> void serialize(const T& value) { std::stringstream stream; stream << value; } So I cannot add any casts :( Maybe I can specialize it somehow? Thank you.

  • Log Shipped but Won't Update

    - by MooCow
    I'm currently taking the MS SQL 2K5 Admin course at a local college and ran into a problem with the Log Shipping part. My setup is the following: Windows 7 x64 SQL 2005 SP3 2 SQL server instances on the same machine Log Shipping settings: Performed full then log back up of Primary Manually restore on Secondary in STANDBY MODE Insert a new record into the table Set up Log Shipping on Primary using SQL Authenication login to connect to the Secondary Set up timers and copy destination on Secondary Monitoring instance not being used I set up a shared folder for WORKGROUP so both instances on the machine can read & write to it. I can see transaction logs generated and copied as defined by the Transaction Shipping wizard. However, the specified table on the Secondary instance is not updating.

  • Best Practice for Exporting an App's Data to XML via PHP/MySQL?

    - by Alex Cook
    I have an a business app and I want to give my users the ability to export their data at anytime. I'm aware that I can write an XML file semi-manually by doing something like this: http://www.kirupa.com/web/mysql_xml_php.htm But, I thought I'd ask if this is the best practice? Or is there some framework I can use to do this more easily/quickly? Maybe there isn't - it won't be too hard to do it the above way. Also, less importantly - XML is the best format to export to, right? Thanks in advance.

  • Exel Question: I need a date and time formula to convert between time zones

    - by Harold Nottingham
    Hello, I am trying to find a way to calculate a duration in days between my, time zone (Central), and (Pacific; Mountain; Eastern). Just do not know where to start. My criteria would be as follows: Cell C5:C100 would be the timestamps in this format:3/18/2010 23:45 but for different dates and times. Cell D5:D100 would be the corresponding timezone in text form: Pacific; Mountain; Eastern; Central. Cell F5 would be where the duration in days would need to be. Just not sure how to write the formula to give me what I am looking for. I appreciate any assistance in advance. Thanks

  • Am I writing this right? [noob]

    private final int NUM_SOUND_FILES = 4; private Random rnd = new Random(4); private int mfile[] = new mfile[NUM_SOUND_FILES]; //the second mfile //reports error everytime mfile[0] = R.raw.sound1; mfile[1] = R.raw.sound2; mfile[2] = R.raw.sound3; mfile[3] = R.raw.sound4; int sndToPlay = rnd.nextInt(NUM_SOUND_FILES); I keep getting syntax errors no matter how I write it.

  • Why is unit testing needed in iPhone / iPad ?

    - by Madhup
    Hi, I am developing an application for iPad application. I need to perform unit testing in the application. But I am not sure why I should do unit testing in this application. The applications in these environments are rather small for unit testing to be written. And since the iPhone sentestingkit is not well documented the implementation and wriiting test cases is so time consuming. So why should we waste time in this? And if we have to what should be the best approach to write test cases? Thanks, Madhup

  • Additional parameters for FileSystemEventHandler

    - by peku
    I'm trying to write a program that could monitor multiple folders for file creations and launch the same action but with different settings for each folder. My problem is in specifying an extra parameter for the FileSystemEventHandler. I create a new FileWatcher for each directory to monitor and add the handler for the Created-action: foreach (String config in configs) { ... FileWatcher.Created += new System.IO.FileSystemEventHandler(FileSystemWatcherCreated) ... } void FileSystemWatcherCreated(object sender, System.IO.FileSystemEventArgs e, MySettings mSettings) { DoSomething(e.FullPath, mSettings); } How could I get the 'mSettings' variable passed to FileSystemWatcherCreated()?
