  • XAML-based applications - Event Naming Conventions for C#

    - by user118190
    For event handling, I am starting to see many coders doing this: XButton.Click += OnXButtonClicked() ... void OnXButtonClicked() { ... } Where did this On_ convention come from? It just doesn't feel right in terms of methods. I am starting to see this as well and am wondering what others thought: XButton.Click += HandleXButtonClick() ... void HandleXButtonClick() { ... } When using intellisense, Visual Studio handles these like so: XButton.Click += XButton_Click; ... void XButton_Click(object sender, RoutedEventArgs e) { ... } I am seeking some advice on these naming conventions and would greatly appreciate some advice.

  • How do you deal with the more mundane parts of programming tasks?

    - by Uri
    My experience as a developer is that many projects or tickets are a mix of a short and focused very interesting task (e.g., designing some API or a platform to solve something) and a lot of repetitive and mundane tasks that cannot be automated (such as certain refactorings to use the API or platform, implementation of certain tests, some GUI handling, etc). I believe that this is the nature of our profession, unless we are high-level architects or managements and can delegate this work. The only item in my personal arsenal when dealing with these tasks is to devote some of my attention to radio or audiobooks (preferably not in English as I find it hard to concentrate on two "streams" of English at the same time). I maintain sufficient attention to carry the task and don't lose concentration as fast. I'm wondering how others cope with these and maintain concentration.

  • Reading long lines from text file

    - by sonofdelphi
    I am using the following code for reading lines from a text-file. What is the best method for handling the case where the line is greater than the limit SIZE_MAX_LINE? void TextFileReader::read(string inFilename) { ifstream xInFile(inFilename.c_str()); if(!xInFile){ return; } char acLine[SIZE_MAX_LINE + 1]; while(xInFile){ xInFile.getline(acLine, SIZE_MAX_LINE); if(xInFile){ m_sStream.append(acLine); //Appending read line to string } } xInFile.close(); }

  • Question about regex in linux commands.

    - by smwikipedia
    I ran the following command at linux bash: apt-cache search hex.*(view|edit) My intention was to find any software packages whose name/description contains the pattern 'hex.*(view|edit)'. But among the results I got this: kipi-plugins - image manipulation/handling plugins for KIPI aware programs How could this be in the results list? I didn't see any matching string in this result. Is this a bug of the apt-cache search command? Or do I mis-understand how the regex is used by this command? Many thanks.

  • How to disable typing in values in Dojo's NumberSpinner?

    - by callie16
    Hi, is there a way to disable typing in of values in the NumberSpinner of Dojo? Or is there a way for me to set back a previous value to it? Here's a sample situation: I have a spinner where the range is 1-3. However, the user types in an invalid value... say, a letter. The usual error handling happens. However, if the user deletes the value and focuses out (e.g. goes to another widget/control/etc. in the page), the spinner stays blank. Either I reset it to the last valid value or I disable typing so that the user can just use the up and down arrows to manipulate the widget. Any thoughts? Thanks!

  • Solr 'text' fields not accepting wild-cards

    - by MarcoPolo
    Hi, I am trying to search on a field declared as 'text' using the wildcard '*' but am getting mixed results. Basically, it seems to me that it's stripping off the '*' character and isn't handling numbers or spaces well. I'm using the 'text' field type for case insensitive fields but after running an analysis, am starting to think itmight be the wrong type to use as it runs a lot more filters when compared with the string field. Basically all I want is a field type that can index or search on lowercase only with spaces stripped out (and works with wildcards). Is such a type available? Thanks MARCO

  • Struts2 plugins - Dojo or jQuery or...?

    - by Trick
    Since Apache Struts has deprecated Dojo plugin from Struts 2.1.x I am thinking to change everything to jQuery. I especially noticed the difference in sizes (170kb vs 19kb - something like that). I had troubles with IE browser with handling dojo scripts, is this happening also with jQuery (when user is working with the application for a long time, script stops running)? I have a lot of dojo tags in my applications, and I use most of theirs attributes. Has anyone had any experience doing that? What were the problems? What were the benefits? Downsides? Does anyone has any better ideas of which plugin to include with Struts2? Any answer will be great! Thanks.

  • Looking for a specific kind of WEB framework, no malarkey please

    - by Hello you all men
    We do maintenence on a number of systems. I'm finally in a place where I'm teh fucking boss for once, and have to design a large system that will have a long maintenance contract. There's a couple of tasks I find myself always repeating: 1) similar tasks for users with JS and those without 2) similar things for contents and rss/atom feeds, etc. To combat these I will need appropriate handling of assets (think JS files, CSS, themes/templates, etc.), excellent auth/user systems, javascript/ajax forethought, appropriate model setups. Codeigniter fails on many of these. Basically, with enough time I could build this system with Zend, but I'm curious what else is out there as Zend is also kind of a heavy-weight. We need something that is Rapid but maintainable, CodeIgniter is not maintainable. We will have a lot of AJAX APIs in place for the design team to play with. At first I thought jQuery was cool, but now I'm looking at Dojo.

  • VB.NET Inputbox - How to identify when the Cancel Button is pressed?

    - by The Sasquatch
    I have a simple windows application that pops up an input box for users to enter in a date to do searches. How do I identify if the user clicked on the Cancel button, or merely pressed OK without entering any data as both appear to return the same value? I have found some examples of handling this in VB 6 but none of them really function in the .NET world. Ideally I would like to know how to handle the empty OK and the Cancel seperately, but I would be totally ok with just a good way to handle the cancel.

  • How to distinguish date at midnight from date w/o time in Oracle?

    - by Swiety
    I would like to distinguish date at midnight (i.e. '12/05/2010 00:00:00') from date without time specified (i.e. '12/05/2010'). This value is provided by user, sometimes it is only date which is important, sometimes it is date and time and later the application is expected to show the time only when it was explicitly provided. So for the following inputs I would expect the following outputs: for '12/05/2010' I would expect '12/05/2010' for '12/05/2010 09:23' I would expect '12/05/2010 09:23' for '12/05/2010 00:00' I would expect '12/05/2010 00:00' I know I can model it in two separate columns, date and time, but I was wondering was there any way of handling this in single date column?

  • Whhether or not it is an elegant way in such a situation?

    - by z_axis
    There are some text files which needed to be manipulated line by line. I wrote a withFile function as below: let withFile fn handle = let rec iter_lines fh = try handle (input_line fh); iter_lines fh with _ -> close_in fh in iter_lines (open_in fn);; So i can manipulate each file as : withFile "file1.txt" (fun line -> (*...*)) withFile "file2.txt" (fun line -> (*...*)) ... But i amnot sure how to exit elehantly when i donot want to handle all lines. For example: withFile "file3.txt" (fun line -> (*when the line meets some condition, i will exit without handling other lines*) ); Any suggestion is appreciated !

  • Firefox DOMParser problem

    - by Michael
    For some reason DOMParser is adding some additional #text elements for each newline \n for this url http://rt.com/Root.rss ...as well as many other RSS I've tried. I checked cnn/bbc feeds, they don't have newlines and dom parser handling them nicely. So I have to add the following before parsing it var xmlText = htmlText.replace(/\n[ ]*/g, ""); var xmlDoc = parser.parseFromString(xmlText, "text/xml"); Server is returning text/xml. var channel = xmlDoc.documentElement.childNodes[0]; this returning \n without my code above and channel with correction.

  • [C#] Creating standalone, console (shell) for domain-specific operations

    - by mr.b
    Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

  • Casting an object which could be null

    - by DeeMac
    DateTime? testDate = (DateTime?)arrayOfObjects[dateObject]; Does that code look ok? I attempted to use the as operator but I got the 'non-nullable' error. What I'm trying to say is that the object I'm choosing from the array is either DateTime or a null DateTime but either can be assigned to testDate. Doesn't feel right doing it this way, I think I'm missing something obvious. EDIT: I suppose it's the same as the way I could've adapted the as in the following way: DateTime? testDate = arrayOfObjects[dateObject] as DateTime?; Is either line of code the best way of handling potential nulls?

  • Comparing 2 linq applications: Unexpected result

    - by lukesky
    I drafted 2 ASP.NET applications using LINQ. One connects to MS SQL Server, another to some proprietary memory structure. Both applications work with tables of 3 int fields, having 500 000 records (the memory structure is identical to SQL Server table). The controls used are regular: GridView and ObjectDataSource. In the applications I calculate the average time needed for each paging click processing. LINQ + MS SQL application demands 0.1 sec per page change. LINQ + Memory Structure demands 0.8 sec per page change. This Is shocking result. Why the application handling data in memory works 8 times slower than the application using hard drive? Can anybody tell me why that happens?

  • Programming Exercises for Learning Purposes?

    - by cam
    Are there any programming exercises that apply to any language? Before I got my first job, I thought I knew C# pretty well, then I was thrown right into the deep end, and now I know I have a good command over the language. I would like to apply the same method to other languages, but unfortunately, I'm sort of stuck with C# at work. Ideally, something similar (but broader in scope) to Project Euler is ideal. Project Euler helped me learn a ton of C++/F#, some math, algorithms, handling bignums, etc. I'm looking for something like this.

  • Which Java Web Framework allows Cross-Domain Javascripting (http proxy) ?

    - by snsd
    So just a quick intro, I am starting to explore Vaadin, and it's absolutely perfect. Previously, I was juggling PHP, Perl, Ruby, and Jquery for designing rich client web application. It didn't work out too well, as I've burnt out from trying to fix cross browser issues (aka get-it-to-work-on-IE-damn-it), handling server-side, client-side, and building a robust communication between the two tier had lot of code not related to application logic....by the time I was burnt out, only tiny bit of application logic was implemented. Vaadin seems like the answer to my problem as it only requires Java and built on top of GWT. However, I am curious how I can incorporate Cross-Domain Javascripting ? Back in LAMP environment, I had a CGI proxy script that loaded external URL, and injected JS into the proxy-loaded page. I used the CGI proxy script, as it rendered Javascript of the external URL well. Is there a class or package for Java or a specific Java web framework similiar to Vaadin that makes this possible ? Thank you.

  • Deploy Java application on MacOSX (from a Windows system)

    - by Matías
    Hello, Here's the deal. I'm just starting with Java programming, I've made a simple application that uses SWT graphic library and I want to deploy it on a Mac (running the latest version of MacOS X). I did all the programming in my Windows 7 machine, so here are my questions: Q1) Can I make an executable file for MacOS X from my Windows machine? How? (I saw that it's possible to create .exe files on Windows, instead of using .jar; I want to do the same for the Mac, of course it won't be an .exe) Q2) If I export my project in Eclipse and I choose Runnable JAR File and then on Library Handling I pick Extract required libraries into generated JAR or Package required libraries into generated JAR I end up with a huge .JAR (about 15MB of size, my application consist in just a button on a Window and a tiny method that doesn't do much). Is that considered normal? Here's the list of libraries that my project appears to be using: Thanks in advance.

  • MVC: Structuring Feed Output

    - by Brian Wigginton
    The framework I'm using on my project follows the MVC Pattern. I"M building JSON feeds and need to structure them in a different way then what the system gives me by default from the ORM. Where should I be handling the task of mangling and shaping my data that I'll serve up, in the model, view or controller? Right now I'm doing it in my controller, then passing that data to the view. I can see this fitting better under the Model or the View but not sure which one.

  • what's the right way to do polymorphism with protocol buffers?

    - by user364003
    I'm trying to long-term serialize a bunch of objects related by a strong class hierarchy in java, and I'd like to use protocol buffers to do it due to their simplicity, performance, and ease of upgrade. However, they don't provide much support for polymorphism. Right now, the way I'm handling it is by having a "one message to rule them all" solution that has a required string uri field that allows me to instantiate the correct type via reflection, then a bunch of optional fields for all the other possible classes I could serialize, only one of which will be used (based on the value of the uri field). Is there a better way to handle polymorphism, or is this as good as I'm going to get?

  • __defineSetter__ on innerHTML stops it from rendering

    - by Tokimon
    Hi, i'm trying to create a watch method for HTML elements, using __define[GS]etter__ when a property is changed. It reacts just fine when i set the value, but if the property listened to, is innerHTML, it somehow fails to render the given string. So basically, when im adding something to innerHTML it doesn't show. Im using the watch method described in this previous question: http://stackoverflow.com/questions/1269633/javascript-watch-for-object-properties-changes I could of cause just not listen to innerHTML changes, but i'm also wondering if the __defineSetter__ somehow prevents original handling of setting the value. Thanks!

  • jQuery - Programmatically Trigger Event

    - by Sonny
    I need to programmatically trigger a click event that's being handled by jQuery. Here's the current code: var $thumbs = $('#PhotoGalleryThumbs .tile'); var $zoom = $('#PhotoGallery #PhotoGalleryZoom img'); var $description = $('#PhotoGallery #PhotoGalleryDescription'); $thumbs.click(function(event) { event.preventDefault(); var $thumb = $(this); $thumb.addClass('selected') .siblings().removeClass('selected'); $zoom.attr('src', $thumb.children('a').attr('href')); $description.html($thumb.find('img').attr('alt')); }); I am having a mental block working out how to create a function out of the event handling code and then arbitrarily calling it for an element in the $thumbs object.

  • How much market shares OpenGL2.0 in iPhone os hardwares(iPhone/iPot Touch)

    - by Eonil
    I'm planning making a game for AppStore, so I'm studying GLES. But, GLES 1.1 and 2.0 APIs are different about handling in some features.(and limitations) I have not enough time to consider both of them, I have to choosing one. 2.0 is clearly better in developer's view, but I'm worry about it's market share. I wish most users moved on newer SGX based hardware, but in fact, I don't know. Does anybody have information about location of those hardware ratio data in iPhone OS supported hardwares? (iPhone/iPod touch, per GPU) Please let me know.
