  • Kind of stumped with some basic C# constructors.

    - by Sergio Tapia
    public class Parser { Downloader download = new Downloader(); HtmlDocument Page; public Parser(string MovieTitle) { Page = download.FindMovie(MovieTitle); } public Parser(string ActorName) { Page = download.FindActor(ActorName); } } I want to create a constructor that will allow other developers who use this library to easily create a Parser object with the relevant HtmlDocument already loaded as soon as it's done creating it. The problem lies in that a constructor cannot exist twice with the same type of parameters. Sure I can tell the logical difference between the two paramters, but the computer can't. Any suggestions on how to handle this? Thank you!

  • Have you been in cases where TDD increased development time?

    - by BillyONeal
    Hello everyone :) I was reading http://stackoverflow.com/questions/2512504/tdd-how-to-start-really-thinking-tdd and I noticed many of the answers indicate that tests + application should take less time than just writing the application. In my experience, this is not true. My problem though is that some 90% of the code I write has a TON of operating system calls. The time spent to actually mock these up takes much longer than just writing the code in the first place. Sometimes 4 or 5 times as long to write the test as to write the actual code. I'm curious if there are other developers in this kind of a scenario.

  • Open Source Code Integrity - How does quality assurance work?

    - by rockinthesixstring
    I've thought about this before and this topic has often steered me away from Open Source projects. Recently DotNetPanel has changed it's name to WebSitePanel and gone Open Source. The rumor mill is speculating that Microsoft is behind this. My question (in multi-part) is quite simple. Can somebody please explain to me how quality assurance works on Open Source projects? How can a closed application get "only better" when Open Source? Doesn't the "too many cooks in the kitchen" theory apply when too many developers contribute (possibly bad) code to a project?

  • Collaborative editing for .NET development - what are the possibilities

    - by Olav
    What are the best options for real-time collaborative editing for .NET development? (C#,VB.NET, ASP.NET - not Mono unless it is the best way to get collaboration) 1) Anything possible with visual studio? 2) Collaborative editors? I know Eclipse has real-time collaboration, but I don't know how far you can combine it with .NET support. 3) Web-based tools? 4) Desktop sharing tools like VNC, NX etc. The main points is that 2 developers in different locations should be able to see edits in real time. Both should be able to edit, or it should be easy to switch control. Regarding .NET, syntax highlighting etc is better than nothing.

  • logic of button to be disabled or not in mvc

    - by rod
    Hi All, Here's an excerpt from a book I'm reading about application design with MVC: Ideally, the view is so simple and logic-free as to need virtually no testing. Users (and developers before users) can reasonably test the view by simply looking at the pixels on the screen. Anything else beyond pure graphical rendering should ideally be taken out of the view and placed in the controller and model. This includes, for example, the logic that determines whether a certain button should be enabled or grayed out at some point. what does the bold statement mean to you? what would this look like? thanks, rod.

  • What software development process do you use and how do you implement it?

    - by clyfe
    Post only what you do use not what you would like to use, so we can see what is the most popular in real life. I am interested only in theese issues: Project Model (waterfall, agile...) How are requirements gathered (and stored)? Revision control - what software, what workflow Build automation, what software, where does it fit ? How is the testing done ? How is the documentation done ? How is the quality assurance done ? Please provide short objective answers, don't speak from the books. EXAMPLE: In my company we are a small team of 5 people and we develop webapps using ruby. agile PM cucumber requirements git SCM - Integration Manager Workflow integrity CI rspec automated tests the project lead creats the documentation skeleton then it is filled by the developers ensure quality by peer reviewing code and manual peer-testing

  • Java - binary compatibility of abstract class & subclasses

    - by thSoft
    In Java, I define an abstract class with both concrete and abstract methods in it, and it has to be subclassed independently by third-party developers. Just to be sure: are there any changes I could make to the abstract class that are source compatible with their classes but not binary compatible? In other words: after they have compiled their subclasses, could I change the abstract class - apart from e.g. adding an abstract method to it or removing a protected method from it that is called by subclasses, which are of course source incompatible - in a way that could force them to recompile their subclasses?

  • How do you authenticate user generated "apps" for your app?

    - by Brian Armstrong
    I'm think something like Facebook apps here. User generated pieces of code that people can write to interact with my app. I understand how an authenticated API works, but this seems a little more complicated because not only does the APP have to authenticate itself (with a regular api-key) but the USER using the app has to be authenticated somehow too, without giving the app free reign. I've been reading a bit here to see how FB does it: http://wiki.developers.facebook.com/index.php/How_Facebook_Authenticates_Your_Application And it looks like you have to pass a signature in addition to the api-key along with every call, but I'm having trouble wrapping my head around how this gets generated and used on the other end (my server). Figure there must be a simple explanation of this out there? Thanks! P.S. I'm building a Rails app if there are any applicable gems/plugins.

  • Mysql stored procedures

    - by Richard M
    Hello, I have a unique issue that I need advice on. I've been writing asp.net apps with SQL Server back ends for the past 10 years. During that time, I have also written some PHP apps, but not many. I'm going to be porting some of my asp.net apps to PHP and have run into a bit of an issue. In the Asp.net world, it's generally understood that when accessing any databases, using views or stored procedures is the preferred way of doing so. I've been reading some PHP/MySQL books and I'm beginning to get the impression that utilizing stored procedures in mysql is not advisable. I hesitate in using that word, advisable, but that's just the felling I get. So, the advice I'm looking for is basically, am I right or wrong? Do PHP developers use stored procedures at all? Or, is it something that is shunned? Thanks in advance.

  • Metatool for automatic xml code generation

    - by iceman
    I want to develop a programming tool for developers which can do automatic xml code generation for specifying a GUI design and its controls. The aim is to allow non-programmers specify GUI controls(which in this case perform higher level task unlike WinForms ) from a GUI. So the xml code generated is essentially an internal representation which programmers can understand and further use in any automatic GUI generator. So the workflow is GUI(non-programmers)-xml(for programmers)-GUI(non-programmers). Is there a Microsoft project similar to this?

  • savedInstanceState cannot be resolved to a variable

    - by Hector
    I'm currently working through "The Android Developers Cookbook" and one of the tutorials involves multiple activities in an app. To give a bit of background right now I have to .java files, a "menu screen" and a "game screen". The menu screen simply has a button that leads to the game screen which is currently empty except for a button that takes you back to the menu screen. Currently the game.java file is giving me a "savedInstanceState error" this is the code I am working on. public void onCreate(Bundle savedInsanceState) { // below is where the error comes up super.onCreate(savedInstanceState); setContentView(R.layout.game); Button startButton = (Button) findViewById(R.id.end_game); startButton.setOnClickListener(new OnClickListener() { public void onClick(View view) { finish(); } }); } I'm not sure why the error is coming up because on the first java file that same "public void...setContentView..." bit of code compiled perfectly fine... Please help!

  • Writing Facebook apps in C#

    - by Water Cooler v2
    Hi, I am a C# developer and fancy the idea of writing a C# app or two to integrate with the Facebook API. I read from this page: http://wiki.developers.facebook.com/index.php/User:C_Sharp that there's this Microsoft SDK for Facebook Platform that has binary assemblies that I can use to write my C# app. As a start, I want to try out the example mentioned on the above-mentioned page -- one that gets me a friend list. The problem is: I am completely new to this Facebook development thing and I see I am going to need, at the very least, an API Key and some Facebook service Secret key or some such, to begin writing some code. Do I also need a developer account? Where do I get all these things from?

  • Development team collaboration via Google Wave

    - by Alex N.
    I hope I am not repeating any previously asked question. Anyway, so Google Wave is nice and shiny and sounds like a lot of folks(at least at Google I/O :) used it in a useful for work(!) way. I've been beta-testing Google Wave for sometime now, but can't quite grasp how to improve our workflow using it. We have a medium size team of developers that are spread out around US and Europe and naturally most of communication is happening via IM and Skype and email of course. So what are specific things that could be offloaded to Google Wave to improve collaboration by leaps and bounds(meaning not just replacing IM with nicer IM)?

  • Examples of networked Flash games

    - by videodnd
    Maybe I am asking the wrong questions, because I don't see any sample projects out there. I know Flash developers have done Kiosks and renovated arcade games. "Come on, we see Flash everywhere." Is there a sample project I could be pointed towards, it would be an ass-saver. Can I prepare my swf files like an image gallery and receive XML commands to load it? Where do I start? Flash/After Effects skills have got me through so far, but I need help!!! It would be fun if it wasn't so stressful. Criteria TCP/IP socket connection Flash package XML commands load swf file in to a container Additional Questions How do I prepare my Flash files and XML sheet to receive commands "any sample out there"? What about e.data, urlLoad, xmlSocket Class, XMLCP/IP XML socket connection to load Is binary or XML method better for loading and reloading swf files? Do I need Red5 or a media server? videoDnd, Ambitious Development Noob

  • where do I submit the ipad apps?

    - by Mike
    I read Apple is allowing developers to submit iPad apps for the great opening of the ipad store, but I cannot find anything in my account that says that or allows sending the apps. Another thing is: in order for an app to be accepted you have to sign it with your own certificate but to do that you have to select the device on Xcode. As far as I know, Xcode do not signs with certificates applications that run on the simulator. Beyond that, any try to build a distribution package on Xcode shows messages like "you should disable armv6", and others. So, I ask. Is this news true? If yes, how to I manage to have the app ready for iPad and ready for submission? thanks.

  • Is there a nice XSL stylesheet for client-side DocBook rendering?

    - by Steven Huwig
    I want the DocBook documents in my SVN repository to look nice if someone looks at them in a web browser. I've started to write a CSS stylesheet, but I think that it will have significant limitations -- particularly ones regarding hyperlinks. There is a large body of DocBook XSL stylesheets at the DocBook site , but they don't seem to be appropriate for browser rendering. I don't want to generate static documents and put them into SVN. I want them to be basically readable for other developers without much hassle. I could write my own browser-appropriate XSL stylesheet to convert DocBook to HTML, but it seems like someone else must have already done this. I just don't know where to find it.

  • Simulate Incorrect Content-Length Headers for HTTP in C#

    - by cfeduke
    We are building a comprehensive integration test framework in C# for our application which exists on top of HTTP using IIS7 to host our applications. As part of our integration tests we want to test incoming requests which will result in EndOfStreamExceptions ("Unable to read beyond end of stream") that occur when a client sends up a HTTP header indicating a larger body size than it actually transmits as part of the body. We want to test our error recovery code for this condition so we need to simulate these sorts of requests. I am looking for a .NET Fx-based socket library or custom HttpWebRequest replacement that specifically allows developers to simulate such conditions to add to our integration test suite. Does anyone know of any such libraries? A scriptable solution would work as well.

  • Custom Providers & Design Patterns

    - by Code Sherpa
    Hi. I am using ASP.NET 2.0 and its various providers. I have overridden most of the methods I need and have the following custom providers: ProjectMembershipProvider ProjectProfileProvider ProjectRoleProvider In the design of my project, my intention was to wrap the custom providers in a facade - style design - mixing and matching profiling, membership, and roles in API methods to simplify things for developers. But, I am finding that a lot of the methods in my custom providers don't need to change, really. And, it seems silly to wrap a stand-alone method in another method that does exactly the same thing. So - is my approach wrong? Or, should I allow end - users to instantiate the custom providers when needed and the mix/match api when needed? This seems a bit redundant to me but I can't see another way. Advice appreciated. Thanks.

  • MFC resource.h command/message IDs

    - by ak
    Hi I'm working on an MFC application, that got pretty messy over years and over different teams of developers. The resource.h file, which contains all command/message mappings grew pretty big over time, and has lots of problems (like duplicate IDs). I am not proficient with MFC, so the question might sound pretty stupid... MSDN docs mention that Command IDs and Message IDs should not be less than WM_USER and WM_APP correspondingly. I saw that most of the command IDs in resource.h generated by Visual Studio begin around 100. Shouldn't this cause some interfering with MFC/Windows commands and messages, that overlap with the application defined IDs? For example, I have a command ID : #define ID_MY_ID 101 and there is a windows command that has the same ID. When MC send this command to the APP, it's handled like an application defined ID_MY_ID, and the app is taking unnecessary actions. Is it a possible scenario? Also, is there some third party tool that helps to profile the project resources?

  • How to gain greater control of network packets on Android

    - by mauvehead
    I'm looking to design an application that will require some deep control over IP packets. Looking over the reference guide on the developers site at Android I see very limited control over packets from java.net:SocketOptions and java.net:DatagramPacket. Specifically I'm looking to control the individual bits within the packet to set TCP Flags, SYN/ACK/RST, and so forth. Based on the docs I am assuming I cannot do this within the Java API provided by Android and I'm guessing I'll have to do it some other way? Anyone have any insight on this?

  • Which distribution website should I pick for my open-source package?

    - by Frank
    I wrote an open-source software package, which I'd like to publish (using Apache 2 license). I see various options for how/where to publish/host it: Get my own domain and put it there Put it on Sourceforge Put it on Google Code Put it on Freshmeat ...? What are your experiences / recommendations? What's the current trend among software developers? My only requirements are that I ... can add my own logo on the website can put up some documentation there, get a nice URL that is easy to remember get SVN support (I would also be fine with just uploading a tarball for each new version, it just shouldn't force me to use CVS or any other version control system I'm not familiar with) and of course, the site shouldn't take ownership in the code etc. oh, and it should be free (ok, for registering my own domain I'll be willing to pay a little bit)

  • .NET Database Apps: Your Preferred Setup

    - by mdvaldosta
    I'm struggling to settle into a pattern for developing typical database driven apps in C# and Visual Studio. There are so many ways to set them up, using drag/drop datasets and adapters or writing the queries manually in ADO.NET or Linq to SQL, Linq to Entities, to bind or not to data bind etc etc. Where to store the connection string, in app.config or in a method or both etc etc. So many tutorials and all of them are different. Everytime I write something I start hating the way it looks and works, so I scrap it and start over. It's getting a bit tedious. Maybe it's alittle of the OCD in me. Would any of you professional developers out there share your method of setting up and structuring your database logic and maybe some sample code? It's really how to go about organizing the code and the method(s) of interacting with SQL that I'm trying to get into a routine with, one that works and won't get me laughed at by someone reviewing it.

  • added TextToSpeech to my activity and now my onDestroy is not called any more, bug?

    - by hermo
    I added TextToSpeech to my app, following the guidelines in the following post: http://android-developers.blogspot.com/2009/09/introduction-to-text-to-speech-in.html and now my onDestroy is no longer called when the back button is pressed. I filed a bug report regarding this: http://code.google.com/p/android/issues/detail?id=7674 Figured i should also ask here if someone else has seen this, and found a solution? It seems that it is the intent that causes the problem, i.e. the following: Intent checkIntent = new Intent(); checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA); startActivityForResult(checkIntent, MY_DATA_CHECK_CODE); If I skip this intent, and just go ahead and create a tts-instance, it works fine. Any clues to what is wrong with this intent?

  • Make object available within php functions without passing them or making them global

    - by Matt
    Hey all, This requirement is just for simplicity for developers and beautiful code. I'm building a template system and I really would just like an object variable to simply be there in all functions. Here's some code: Librarian.php: $class = "slideshow"; $function = "basic"; $args = array(...); $librarian = $this; // I WOULD LIKE THIS TO BE PRESENT IN CALLED FUNCTION ... return call_user_func($class.'::'.$function, $args); ... Slideshow.php: public static function basic($args) { echo $librarian; // "Librarian Object" } Thanks! Matt Mueller
