  • Application security issues to consider

    - by user279521
    I am working on the design of a high security application (involving financial information, personal information etc). I need to identify what security measures (application level) will be implemented. The application will involve sending data to and from a database, user login, import export to csv, txt files, and print function. What security features do I need to consider for such an application. (SQL injection for starters) ?

  • Moving graphical components with the mouse in Visual Studio

    - by Anto
    I have just installed Visual Studio.NET. In the Design area I have added some graphical components (button, textbox) but I can't move these within the specified area, as their position remains unchanged. I would like to move these graphical components with the mouse cursor, I know it's possible, does anyone know how?

  • In c++ is there any Events/delegates/interfaces/notifications! anything?

    - by Bach
    Say i have these classes ViewA and ViewB In objective C using the delegate pattern I could do @protocol ViewBDelegate{ - (void) doSomething(); } then in ViewB interface: id<ViewBDelegate> delegate; then in ViewA implementation i set the delegate: viewB.delegate = self; and now I can call in doSomething from viewB onto any that unknown type delegate. [delegate doSomething]; "C++ How to Program" has been the worse read an can't find simple examples that demonstrates basic design patterns. What i'm looking for in C++ is: events ActionScript and java either delegates or notifications in Objective C anything that allows class A, Class B and Class C to know that ClassX didSomething()!!! thanks

  • What are the best tricks for learning how to -think- in Objective-C?

    - by Braintapper
    Before I get flamed out for not checking previous questions, I have read most of the tutorials, and have Hillegass' book, as well as O'Reilly's book on it. I'm not asking for tips on Cocoa or what IDE to use. Where my issue lies - my 'mental muscle memory' is making it hard for me to read Objective-C code. I have no problems at all reading Java and C code and understanding what's going on. Maybe I'm getting to old to learn a new syntax, but it's a struggle shifting mental gears and looking at Objective-C code and just "getting it" (I thought it might be an isolated case, but I have other friends who are seasoned devs who have said the same thing). Are there any tricks that any non-Objective-C programmers who now know Objective-C used to help process the syntactical differences when learning it? For some reason, I get dyslexic when reading Objective-C code. Maybe I'm not meant to be able to learn it (and that's ok too). I was hoping/wondering if there might be others who have had the same experience.

  • What setup in .Net would most resemble Django

    - by Mingus Rude
    At work we are inte process of starting development on a new web-based product. Before doing so we need to establish what technology stack we are going to use. For this application my preference would have been to use Django but since the development- and management-team is soo heavily rooted with Microsoft the new product will have to be based on Microsoft technologies. So my question is, what setup, with Microsoft technologies, would most resemble a django setup with its MVT-design?

  • Would the world be a better place if there were only one programming language?

    - by Simon
    Well, perhaps not the world, but would it encourage more-re-use, less replication of basic code, or at least an uplift in what is considered basic code, more time advancing the application science and a greater encouragement to share, a more advanced base of understanding for new programmers, since the language could be taught ubiquitously and patterns of teaching would have emerged which were optimised for students learning etc etc? I think all of those things would make the programming world better and would probably have significant commercial benefit too. This is definitely not a religious debate about which language is best, and is predicated on the notion of some super-being having designed the perfect language to start with, which was improbable, but it strikes me that if, from the beginning, there were only a single programming language we may be further along in terms of the evolution of the software industry and software science. And although it is now impossible, if you buy some or all of these assertions is there an argument for standardising on a single language for the future so we can accelerate our collective progress rather than all of us re-inventing some part of the same wheel and consigning our children to the same fate?

  • Should enumerations be placed in a separate file or within another class?

    - by Icono123
    I currently have a class file with the following enumeration: using System; namespace Helper { public enum ProcessType { Word = 0, Adobe = 1, } } Or should I include the enumeration in the class where it's being used? I noticed Microsoft creates a new class file for DockStyle: using System; using System.ComponentModel; using System.Drawing.Design; namespace System.Windows.Forms { public enum DockStyle { None = 0, Top = 1, Bottom = 2, Left = 3, Right = 4,. Fill = 5, } }

  • Programming texts and reference material for my Kindle DX, creating the ultimate reference device?

    - by mwilliams
    (Revisiting this topic with the release of the Kindle DX) Having owned both generation Kindle readers and now getting a Kindle DX; I'm very excited for true PDF handling on an e-ink device! An image of _Why's book on my Kindle (from my iPhone). This gives me a device capable of storing hundreds of thousands of pages that are full text search capable in the form factor of a magazine. What references (preferably PDF to preserve things such as code samples) would you recommend? Ultimately I would like reference material for every modern and applicable programming language (C, C++, Objective-C, Python, Ruby, Java, .NET (C#, Visual Basic, ASP.NET), Erlang, SQL references) as well as general programming texts and frameworks (algorithms, design patterns, theory, Rails, Django, Cocoa, ORMs, etc) and anything else that could be thought of. With so many developers here using such a wide array of languages, as a professional in your particular field, what books or references would you recommend to me for my Kindle? Creative Commons material a plus (translate that to free) as well as the material being in the PDF file format. File size is not an issue. If this turns out to be a success, I will update with a follow-up with a compiled list generated from all of the answers. Thanks for the assistance and contributing! UPDATE I have been using the Kindle DX a lot now for technical books. Check out this blog post I did for high resolution photos of different material: http://www.matthewdavidwilliams.com/2009/06/12/technical-document-pdfs-on-the-kindle-dx/

  • JPA in distributed Java EE configuration

    - by sof
    Hello, I'm developing a JEE application to run on Glassfish: Database (javaDB, MS SQL, MySQL or Oracle) EJB layer with JPA (Toplink essentials - from Glassfish) for database access JSF/Icefaces based web UI accessing the EJB layer The application will have a lot of concurrent web client, so I want to run it on different physical servers and use a load-balancer. My problem is now how to keep the applications synchronized. I intend to set up multiple servers, each running Glassfish with my EAR app installed. Whenever on one of the servers data is added to or removed from the database (via JPA, no direct SQL queries), this change should be reflected in the JPA layer on the other servers. I've been looking around for solutions to this, but couldn't find anything I really like (the full Toplink from Oracle claims to have a solution, but don't know). Doing a refresh before every access to a JPA entity could work, but is far from efficient. Are there any patterns, libraries, ... that could help here? Thanks a lot!

  • Display different layout according to Facebook connection status in Android

    - by Rom Freiman
    I'm building an Android application where I want users to connect by their facebook details. According to my design, when the application starts first time, I want to display a layout with LOGIN facebook button. After the user will perform login for the first time, I dont want to display this layout/activity again - when the application would be relanched, I want t display another (home) screen, and not the LOGIN one. How should I implement this functionality? Thanks

  • Why does Mercurial only have one level of rollback?

    - by Nick Pierpoint
    I understand the restrictions of rollback and the care required in its use (for example, http://www.selenic.com/mercurial/hg.1.html#rollback), but I just wondered why there is only 1 level of rollback. My guess it's a design decision and that the hassle of storing multiple previous transactional states to handle multiple levels of rollback is more trouble than its worth.

  • GAE transaction exception suggestion

    - by bach
    Hi, The current situation encourages the design of the system to split object fields to seperate objects in order to reduce the chance of the JDOCanRetryException to be thrown. If we could have the fields that were changed by the other client who changed the object in the exception content itself we could deside whether to re-retrieve the object or ignore...

    If you view this URL, you'll see that GitHub is posting all sorts of technical information. Is this a good practice so that users can email info to you about bugs, etc? http://waitdownload.github.com/cheetahtemplate-cheetah-v2.4.2-0-gd20b523.zip It's at least a good design for an error page.

  • Django test client gets 301 redirection when accessing url

    - by Michal Klich
    I am writing unittests for django views. I have observed that one of my views returns redirection code 301, which is not expected. Here is my views.py mentioned earlier. def index(request): return render(request, 'index.html', {'form': QueryForm()}) def query(request): if request.is_ajax(): form = QueryForm(request.POST) return HttpResponse('valid') Below is urls.py. urlpatterns = patterns('', url(r'^$', 'core.views.index'), url(r'^query/$', 'core.views.query') ) And unittest that will fail. def so_test(self): response = self.client.post('/') self.assertEquals(response.status_code, 200) response = self.client.post('/query', {}) self.assertEquals(response.status_code, 200) My question is: why there is status 301 returned?

  • Looking for a good C++/.net

    - by Michael Minerva
    I have recently started to feel that I need to greatly improve my C++ skills especially in the realm of .net. I graduated from a good four year university with a degree in computer science about 9 months ago and I have since been doing full time contract work for a small software company in my local area. Most of my work has been done using Java/lisp/cocoa/XML and before that most of my programming in my senior year was in java/C#. I did a decent amount of C++ in my Sophomore year and in my free time before that but I feel that my general knowledge of C++/.net is very lacking for the opportunities that are now coming my way. Can anyone recommend a good book that could help me get up too speed? I feel I do not need a very basic introduction to C++ but something that covers the fundamentals of .net would be good for me. So basically what I need is a book or books that would be good for a .net novice and a C++ developer who is just beyond novice. Also, a book that would help bein an interview by giving me a conversional understanding of C++ would be great. Thanks a lot!.

  • Regex pattern help (I almost have it, just need a bit of expertise to finish it)

    - by Mohammad
    I need to match two cases js/example_directory/example_name.js and js/example_directory/example_name.js?12345 (where 12345 is a digit string of unknown length and the directory can be limitless in depth or not exist at all) I need to capture in both cases everything between js/ and .js and if ? exists capture the digit string after ? This is what I have so far ^js/(.*).js\??(\d+)? This works except it also captures js/example_directory/example_name.js12345 I want the regex to ignore that. Any suggestions? Thank you all!
