• Is there a Windows API to modify file type associations for an extension?

  - by JohnFx

  I'm looking for a way to programatically tweak the particulars of a file association on a Windows system. For example, the "Application User to Perform this Action" setting for the "Open" action for a particular file type. Clearly I could do this by modifying the registry directly, but if there is an API I'd prefer to use that as it would likely be more resilient to changes in the OS handling of mapping extensions to applications. For my purposes I'm needing to write this in VBScript (.VBS) file because it is part of a package to be used with VMWare ThinApp that mandates it. However, I'll port/wrap/whatever I need to make this week, so I am open to any solution (including using the .NET framework)

• .Net opening and closing database connections

  - by Dan

  I designed the data access portion of our framework so that every time a business object needs to interact with the database it would have to open a connection, invoke the data access layer (to execute the query), and then close the connection. Then if it needed to run in a transaction it would open the connection, begin the transaction, invoke the data access layer (to execute the query) and then commit the transaction, close the transaction, and finally close the connection. I did it this way with the mindset of open late and close early... but what if I needed to call other BO's to submit data in a single transaction? Is there a better way to handle opening and closing connections as well as working with transactions? I'm a rookie in designing application architecture so I hope I'm not doing this wrongly... any help is appreciated.

• what do I need to start developing in .NET

  - by Mahew

  Hi All, thanks in advance for your time, Over the last year I have moved from a beginner PHP developer to a more intermediate developer, I use Mac OS X and a local development server environment (MAMP). I am thinking about starting to develop using the .NET framework. Can anyone give me some advice? What do I need to begin? How similar is .NET to PHP? What is the relationship between ASP and .NET? Is there anything novel or vital I should know about developing in .NET? (I know .NET is written using microsoft technologies...) Anything of use would be valuable! Cheers!

• How can I change the name of a dynamic assembly after it has been created?

  - by Samuel Jack

  Is there any way to change the name of a dynamic assembly after it has been created? I'm using a framework that uses dynamic methods, and it is creating a dynamic assembly with the same name as my main assembly (which causes problems with WPF when it tries to load resources). So I need to find a workaround, and I thought of trying to change the name of the dynamic assembly. I've tried using GetName() and then setting the Name property, but it appears that GetName returns a clone of the name because my change doesn't stick. What else can I try?

• XCode newbie: How to find the source code for standard or system libraries?

  - by Jan Hettich

  XCode newbie question here: If I'm programming in C++ or objective C, and I #include or #import a library; e.g. #include <iostream> #import <Cocoa/Cocoa.h> I'm often not sure where to look for these header files in the directory structure on my Mac. In other development environments, you can right click the included or imported filename and have the option to jump to source. Is there such a feature in XCode? Also, for the standard C++ libraries and the Cocoa framework, is the source code for the implementation files available, or only the headers together with compiled link libraries? Thanks!

• Using VRaptor3 with Tomcat UnpackWARs property setted to false

  - by VinTem

  Hi there, I have to deploy my web app to a tomcat container with the unpackWARs property defined to false. When I do that, although the application is successfully deployed, when I try to access my url I always got a 404 error. I just don't receive that error when I try to access a direct file like index.html for instance. But I can't do that, the VRaptor framework is responsible for routing my url to the jsp file. Does anyone know if I have do anything else? Thanx

• JUnit tests for POJOs

  - by Ryan Thames

  I work on a project where we have to create unit tests for all of our simple beans (POJOs). Is there any point to creating a unit test for POJOs if all they consist of is getters and setters? Is it a safe assumption to assume POJOs will work about 100% of the time? Duplicate of - Should @Entity Pojos be tested? See also Is it bad practice to run tests on a DB instead of on fake repositories? Is there a Java unit-test framework that auto-tests getters and setters?

• XPCOM support in Android webkit browser?

  - by Krish

  Does the Android WebKit supports the XPCOM framework or NPRuntime API`s as like Firefox? How to implement JavaScript in the Android WebKit plug-in? Update: I am writing a media player plug-in for the Android WebKit browser and my plug-in needs to get the command from the web page through JavaScript (some actions like play/pause/stop/resize are issued as JavaScript commands from the browser). My plug-in is written in native C code. Are there any examples or sample plug-in available for JavaScript communication?

• In-Proc SxS opens for shell extension in managed code?

  - by Jens Granlund

  The recommendation used to be "Do not write in-process shell extensions in managed code." But with .NET Framework 4 and In-Process Side-by-Side the main reason not to write shell extensions in managed code should be resolved. With that said, I have three questions. Is it now okay to write shell extensions in managed code? Which problems, if any might there be with writing shell extensions in managed code? What reasons might there be to write shell extensions in unmanaged code?

• How can I Convert XML to an Object using Spring 3.0 mvc while making RESTful request

  - by brock

  Hi, I'm using the Spring 3.0 RC1 framework and I'm currently testing out Spring mvc. I wanted to use Spring mvc to handle restful requests. I have set up my controller to handle the URI request. I am passing in xml with the request. So on the controller I have a method like follows: public void request(RequestObject request) { doSomething(); } I am having a hard time converting the xml to the RequestObject. I haven't seen much documentation on this and I was wondering if anyone could point me in the right direction. I'm guess that you would have to annotate the RequestObject using JAXB or something in order to tell Spring to convert the xml file to RequestObject but I'm not sure. Thanks for all of your help!!

• UIScrollView resizes when a UIViewController is pushed in UINavigationController. Why?

  - by user210504

  Hi! When I push a UIViewController within a UINavigationController, the UIScrollView in the view changes dimensions. Now even I am trying to resize the UIScrollView. It wont simply resize. It maintains the framework dimensions. Any idea why this would be happening. Example: My NIB has a view which has a scrollview with dimensions (320, 430) now when I push the UIViewController associated with the view the scrollview still shows dimensions has 320, 430, but is drawn much smaller then 320,430 Any suggestions in this regard.

• Creating Mock object of Interface with type-hint in method fails on PHPUnit

  - by Mark

  I created the following interface: <?php interface Action { public function execute(\requests\Request $request, array $params); } Then I try to make a Mock object of this interface with PHPUnit 3.4, but I get the following error: Fatal error: Declaration of Mock_Action_b389c0b1::execute() must be compatible with that of Action::execute() in D:\Xampp\xampp\php\PEAR\PHPUnit\Framework\TestCase.php(1121) : eval()'d code on line 2 I looked through the stack trace I got from PHPUnit and found that it creates a Mock object that implements the interface Action, but creates the execute method in the following way: <?php public function execute($request, array $params) As you can see, PHPUnit takes over the array type-hint, but forgets about \requests\Request. Which obviously leads to an error. Does anyone knows a workaround for this error? I also tried it without namespaces, but I still get the same error.

• SharePoint 2010 and VS 2010 - which releases work well?

  - by Jonesie

  I'm having a hard time finding a combination of sharepoint and vs releases that work well together. So far I have tried: SP 4730 & VS RTM SP 4747 & VS RC SP 4763 (Debug RTM ish) & VS RC All of these had issues in one or both products. I'm now reverting to SP 4747 & VS RTM. Has anyone else found a combo that works well? Specifically, I'm creating a service application with some sync framework goodness. I get errors when deploying from vs or running the powershell cmdlets to deploy and provision stuff. Thanks

• jquery noConflict not working in IE8 only

  I have a website using the prootype framework and I am looking to use a jquery plugin. Everything works just not in IE8. It works in ie7 which amazes me. Any idea what maybe wrong? jQuery.noConflict(); function OpenUp(sURL){ window.open(sURL,null,'height=560,width=820,status=yes,toolbar=yes,menubar=yes,location=yes,resizable=yes,scrollbars=yes',false); } jQuery(document).ready(function($) { $("head").append("<link>"); css = $("head").children(":last"); css.attr({ rel: "stylesheet", type: "text/css", href: "/my/docs/jquery.simplyscroll.css" }); $("#scroller").simplyScroll({ autoMode: 'loop', framerate: 1, speed: 1 }); }); I also tired the following: var $j = jQuery.noConflict(); var j = jQuery.noConflict(); everythig works just not in IE8 alone.

• How to do a sample rate conversion in Windows (and OSX)

  - by Paperflyer

  I am about to write an audio file converter for my side job at the university. As part of this I would need sample rate conversion. However, my professor said that it would be pretty hard to write a sample rate converter that was both of good quality and fast. On my research on the subject, I found some functions in the OSX CoreAudio-framework, that could do a sample rate conversion (AudioConverter.h). After all, an OS has to have some facilities to do that for its own audio stack. Do you know a similar method for C/C++ and Windows, that are either part of the OS or open source? I am pretty sure that this function exists within DirectX Audio (XAudio2?), but I seem to be unable to find a reference to it in the MSDN library.

• Dealing with multiple parameters in Nginx rewrite

  - by x3sphere

  I have a rewrite that nginx calls like so: location ~* (css)$ { rewrite ^(.*),(.*)$ /min/index.php?f=$1,/min/$2 last; } And it's used on pages like this: http://domain.com/min/framework.css,dropdown.css Works all fine and dandy, but it's not scalable. Adding another element to the URL means I have to directly edit the nginx config. Ideally, I'd like to have nginx rewrite according to how many comma-delimited parameters are passed through the URL, rather than setting a fixed amount in the config. Is this possible?

• Simple object creation with DIY-DI?

  - by Runcible

  I recently ran across this great article by Chad Perry entitled "DIY-DI" or "Do-It-Yourself Dependency Injection". I'm in a position where I'm not yet ready to use a IoC framework, but I want to head in that direction. It seems like DIY-DI is a good first step. However, after reading the article, I'm still a little confused about object creation. Here's a simple example: Using manual constructor dependency injection (not DIY-DI), this is how one must construct a Hotel object: PowerGrid powerGrid; // only one in the entire application WaterSupply waterSupply; // only one in the entire application Staff staff; Rooms rooms; Hotel hotel(staff, rooms, powerGrid, waterSupply); Creating all of these dependency objects makes it difficult to construct the Hotel object in isolation, which means that writing unit tests for Hotel will be difficult. Does using DIY-DI make it easier? What advantage does DIY-DI provide over manual constructor dependency injection?

• ASP.NET-MVC2 Preview 1: Are There Any Breaking Changes?

  - by Jim G.

  I was following Steven Sanderson's 'Pro ASP.NET MVC Framework' book. On page 132, in accordance with the author's recommendation, I downloaded the ASP.NET MVC Futures assembly, and added it to my MVC project. Then, without encouragement from the author, I downloaded, installed, and incorporated the ASP.NET MVC2 Preview 1 dlls into my project. Now, I can no longer load the website. That is, when I hit F5 in Visual Studio, I get this error. In retrospect, I think it was a really bad idea to assume that ASP.NET MVC2 Preview 1 would only be additive; but I'd like other people to weigh in. Has anyone noticed any breaking changes in ASP.NET MVC 2 Preview 1? Also - Has anyone noticed any changes that impact Castle Windsor? Also, please let me know if I should be mindful of IIS6 vs. IIS7 ramifications.

• Advice needed from PHP/Cake PHP expert

  - by Hiro

  I'm very new to programming (besides SQL and databases), but I ultimately want to master Cake PHP for web development. Now, given how new I am, I'm rather lost as to how I get started. Down the road, I want to use MVC framework so that I help myself be disciplined in the way I build. However, I know basic knowledge of PHP and OOP PHP are required. So my question is this: what are the right steps to mastering Cake PHP? I don't want to skip critical phases of learning before learning to Cake PHP. At the same time, I don't want to spend more time than required learning PHP if I can learn it directly through Cake PHP knowledge. Any advice would be appreciated.

• How to build an interactive search engine web interface using python

  - by asmaier

  I have build a static web interface for searching data from some tables in my PostgreSQL database. The query website consists of a simple textfield for entering the search term, the result website presents the results as a simple html table. The server side code for searching the PostgreSQL database and returning the results is written in python using psycopg2. Now I would like to add some interactive "Ajax features" to my search engine. When entering the search term I would like to be able to see a list of possible search terms like Google does it. On the results page, I would like to be able to sort the table showing the results. What would be the easiest/recommended way to implement these features for my search engine web site? Do I need a full-fledged web framework like Django for that?

• How can I implement forum privileges

  - by RobertPitt

  I've started developing a forum application in PHP on my MVC Framework and I've got to the stage where I assign permissions to members (for example: READ, WRITE, UPDATE, DELETE). Now, I know I can add 5 columns under the user table in my database and set them to 1 | 0, but that to me seems like too much if I want to add other rules, like MOVE for example. And how can I dynamically assign these privileges them to users individually? I've heard of using a bitmasks, but it would be really good if I could fully understand them before I continue. Do you have an example of how I might implement this?
