• ASP.NET MVC, JSON & non JavaScript clients

  - by redsquare

  I need to ensure that an application I am developing is accessable and also works with JavaScript turned off. I just need a pointer to assist with the following. I had 3 'chained' select boxes and I wanted JavaScript enabled clients to have a nice Ajax experience. I can easily write the required functionality to populate the chained boxes on the change event of the preceeding select using jQuery and JSON with a WCF service. However what about the non JavaScript client? Would I wrap a submit next to the select and place these inside their own form to post back with a certain action or different querstring parameter? Can the same controller give me a partial JSON response as well as feeding the full HTML response. Can anyone point me to a good demo that utilises both JSON and normal HTTP posts to produce the same result in ASP.NET MVC. All ASP.NET MVC demo/examples I see forget about the non JavaScript enabled client.

• Problem with superfish submenu being trimmed by content in Firefox

  - by da5id

  Greetings, I have a problem which would seem to involve some kind of z-index issue, but for a change it's in everything except IE. If you take a look at http://cougar.motivo.com.au/ in anything except Internet Explorer and hover over the last menu item "Contact Us" you can se what I'm referring to. Basically the supersub menu appears to be being trimmed by the width of the element below it. You can see via the source that I've tried setting z-indexes & position:relative, but at this point I'm stumped. Any and all input would be gratefully received :) P.S. I am aware that there are still a couple of issues in IE6. I am yet to have the pleasure of addressing those (groans).

• Extracting a Rails application into a plugin or engine

  - by Globalkeith

  I have a Rails 2.3 application which I would like to extract into a plugin, or engine. The application has user authentication, and basic cms capabilities supported by ancestry plugin. I want to extract the logic for the application into a plugin/engine so that I can use this code for future projects, with a different "skin" or "theme" if required. I'm not entirely sure I actually understand the difference between plugin and engine concepts, so that would be a good first point. What is the best approach, are there any good starting points, links, explanations, examples that I should follow. Also, with the release of R3 to consider, is there anything that I should be aware of for that, with regards to plugins etc. I am going to start off by watching Ryan's http://railscasts.com/episodes/149-rails-engines but obviously thats over a year old now, so one of the challenges I'm faced with is finding the most up to date and relevant information on this subject. All tips and help gratefully received.

• JavaScript OnClick Handler Not Invoking

  - by potatolicious

  I'm calling a javascript function in an inline onclick like so: <a href="#" onclick="removeAttribute('foo', 'bar');">Some Link</a> When I click on the link, though, nothing happens. I have other links (to other functions) tied to onclicks that work fine elsewhere on the same page. All links to this "removeAttribute" function fail. There are no errors in Firebug, and the onclick event handler is being invoked - but stepping into the removeAttribute function ends up, for some reason, somewhere in jQuery.js. At no point does removeAttribute ever get called. If I do: javascript:removeAttribute('foo', 'bar'); in Firefox's address bar. The function is called successfully. Anyone seen this?

• Popuplating an NSPopupButton with the contents of two NSArrayControllers

  - by ndg

  I'm looking to populate an NSPopupButton with the contents of two NSArrayControllers. The NSArrayControllers are both bound to my Core Data Managed Object Context and represent separate entities (in this example: Person and Department). Within my NSPopupButton, I would like a list of departments, and the people that work under them. Like so: Department 1 Person 1 Person 2 Department 2 Person 3 Person 4 All departments would need to be disabled by default, meaning that users should only be able to select people listed within the dropdown. I'm lost as to how I would go about doing something like this. The concept of manually populating an NSPopupButton seems fairly trivial, but I'm a bit shaky as to best to populate the element with Core Data objects. Essentially, I'm just looking for someone to point me in the right direction. I imagine there's a right way to do this, and a number of very wrong ways.

• Passing an array for setting variable

  - by mathk

  Hi, I often see this idiom when reading php code: public function __construct($config) { if (array_key_exists('options', $config)) { ... } if (array_key_exists('driver_options', $config)) { ... } } Here I am concern with the way the parameter is used. If I were in lisp I would do: (defun ct (&key options driver_options) (do-something-with-option-and-driver_option)) But since I am in PHP I would rather have a constructor that take a list of parameter and let them be null if there a not require. So what do you guys think about having an array as parameter in other to do some initialization-or-whatever? In other to answer you have to take in account the point of view of the user of the function and the designer of the API. Also have you ever heard this has a code-smell? thanks

• best method of turning millions of x,y,z positions of particles into visualisation

  - by Griff

  I'm interested in different algorithms people use to visualise millions of particles in a box. I know you can use Cloud-In-Cell, adaptive mesh, Kernel smoothing, nearest grid point methods etc to reduce the load in memory but there is very little documentation on how to do these things online. i.e. I have array with: x,y,z 1,2,3 4,5,6 6,7,8 xi,yi,zi for i = 100 million for example. I don't want a package like Mayavi/Paraview to do it, I want to code this myself then load the decomposed matrix into Mayavi (rather than on-the-fly rendering) My poor 8Gb Macbook explodes if I try and use the particle positions. Any tutorials would be appreciated.

• WPF with code only

  - by rwallace

  I've seen a lot of questions about the merits of WPF here, and essentially every answer says it's the bee's knees, but essentially every answer also talks about things like XAML, in many cases graphic designers and Expression Blend etc. My question is, is it worth getting into WPF if you're a solo coder working in C# only? Specifically, I don't have a graphic designer, nor any great talent in that area myself; I don't use point-and-click tools; I write everything in C#, not XML. Winforms works fine in those conditions. Is the same true of WPF, or does it turn out that important functions can only be done in XAML, the default settings aren't intended for actual use and you have to have a graphic designer on the team to make things look good, etc., and somebody in my position would be better off to stick to Winforms?

• What is the chance a CouchDB document update handler will get a revision conflict?

  - by jhs

  How likely is a revision conflict when using an update handler? Should I concern myself with conflict-handling code when writing a robust update function? As described in Document Update Handlers, CouchDB 0.10 and later allows on-demand server-side document modification. Update handlers can process non-JSON formats; but the other major features are these: An HTTP front-end to arbitrarily complex document modification code Similar code needn't be written for all possible clients—a DRY architecture Execution is faster and less likely to hit a revision conflict I am unclear about the third point. Executing locally, the update handler will run much faster and with lower latency. But in situations with high contention, that does not guarantee a successful update. Or does the update handler guarantee a successful update?

• Limiting the number of threads executing a method at a single time.

  - by Steve_

  We have a situation where we want to limit the number of paralell requests our application can make to its application server. We have potentially 100+ background threads running that will want to at some point make a call to the application server but only want 5 threads to be able to call SendMessage() (or whatever the method will be) at any one time. What is the best way of achieving this? I have considered using some sort of gatekeeper object that blocks threads coming into the method until the number of threads executing in it has dropped below the threshold. Would this be a reasonable solution or am I overlooking the fact that this might be dirty/dangerous? We are developing in C#.NET 3.5. Thanks, Steve

• PHP/Mysql issues

  - by queryne

  Php/my sql newbie question. I have a database I've imported into my local phpmyadmin. However it seems I can't access it from my a php application. The connection string seems right and when i try to authenticate user credentials to access database information, no problems. However authenticate everyone and knows when i put in fake credentials. Still it won't pull any other information from the database. For instance, once a users login they should see something like, "Hello username"... that kind of thing. At this point I see "Hello" without the username. Any ideas what i might be missing?

• Can I get information about the IIS7 virtual directory from Application_Start?

  - by Keith

  I have 3 IIS7 virtual directories which point to the same physical directory. Each one has a unique host headers bound to it and each one runs in its own app pool. Ultimately, 3 instances of the same ASP.NET application. In the Application_Start event handler of global.asax I would like to identify which instance of the application is running (to conditionally execute some code). Since the Request object is not available, I cannot interrogate the current URL so I would like to interrogate the binding information of the current virtual directory? Since the host header binding is unique for each site, it would allow me to identify which application instance is starting up. Does anyone know how to do this or have a better suggestion?

• Getting WAP embedded video in android AND iphone?

  - by Jon

  Recently a client asked me to make their site "work on smart phones", which normally wouldn't be too much of an issue... However it's a video site, and I have absolutely no idea where to even begin. Right off the bat I'm not even going to consider allowing the site to even function in anything other than Android (Maybe even 2.0+) and iPhone, maybe Blackberry and WinMo. But beyond that... What do I do? I'm looking at using the tag, however I'm unsure what, if any, codecs which phone uses. Is HTML5 even adopted in their browsers yet? Could someone please point me in the right direction? Am I going about this the right way, using the tag? Or is there some magical html element both iPhone and Android (And BB and WMo) that lets them run video in their native video players (Like on youtube).

• where do i put html files in my web-app folder for a lift project with maven?

  - by egervari

  I'm new to Lift framework for scala. For some reason, index.html resides in the web-app directory, and when I start up jetty, http://localhost:8080/ will point to that index.html file just fine. However, if I put a login.html file in the same folder as the index.html, and then go http://localhost:8080/login, Lift does not serve the file. Where do I need to put the files to get them register? I am a little lost because the behaviour only seems to work for index.html and nothing else. This is what happens when I view source in Chrome: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <body>The Requested URL /login was not found on this server</body> </html>

• ORMs and Constructors

  - by Harper Shelby

  I'm looking over .NET ORM implementations, and I have a major burning question - are there any .NET ORM implemenations that don't require public properties for every field in the database? When I see examples like this, a little bell goes off in my head. I firmly believe in encapsulation, and being forced to open the kimono of my objects just to make them work nicely with persistence frameworks gives me the heebie-jeebies. Is this sort of accessibility required in all ORMs out there? If not, please point me to examples of those that don't need it!

• Support both Standard mode and Quirks mode? Is that possible and necessary?

  - by tshao

  Today I was assigned a bug saying that some page elements don't work on IE8 Quirks mode at all, and I need to fix them. The point is that I believe our pages will always be rendered in Standard mode, because we specify DOCTYPE at the beginning of every page (via master page). I'd think it must be some debugging tools changed that during testing. I managed to convice QA to close it as by design, after a brief explanation to her. Now I start to think the question that whether we should have our page work on both Standard and Quirks mode. Maybe we should try to minimize the problem even if the page is not rendering in a supposed mode? Any standard or best practices on that? Thanks!

• Does Google provide any Android tutorials that teach how to implement a Service?

  - by Bub

  I apologize in advance for the "newbie" nature of this question. Here is my predicament: I'm brand new to android and developing in general. I'm using android's SDK with eclipse Galileo. I've followed several tutorials to create different layouts. I've even learned recently how to use radio buttons and verify which ones were selected. Now I need to create a service that downloads and updates an xml file within the application. I've tried to locate a simple tutorial for services on Google's developer site but so far, so bad. If they exist could somebody point me in the right direction? On the other hand, I've been told Google's tutorials are a little out dated. Is that true? If so, are there any other tutorials that would hand-hold (and possibly over-explain) how to use a service to a true newbie for free (like google)? Any suggestions would be appreciated.

• Gendarme Rules Customisation

  - by Apogee

  Does anyone know the correct way to explicitly specify which rules Gendarme will use? Or which rules to exclude? I'm not having a lot of joy searching the Mono documentation for the answer. What I'm trying to do is to specify the rules one by one in the Gendarme rules.xml file like this: <rules include="AvoidAssemblyVersionMismatchRule" from="Gendarme.Rules.BadPractice.dll"/> Doing this, I'm hoping we can then switch off the rules we don't care about. The problem is, after specifying all the rules in this way, I'm getting a different number of defects detected compared with when I use the default method Gendarme provides, which is of the form: <rules include="*" from="Gendarme.Rules.BadPractice.dll"/> <rules include="*" from="OTHER DLL NAMES"/> Has anyone done this before? Or can anyone point me in the direction of some Gendarme rules usage documentation?

• Detect whether certain IIS features are present from InstallScript

  - by Christian Hayter

  I have an InstallScript project written in InstallShield 2010, which, amongst other things, shells out to several .NET MSI installers that install web apps. If any of these web apps are selected for installation by the end user, I need to check for the following optional IIS features from InstallScript code before allowing the install to proceed: ASP.NET (IIS 6+) WCF HTTP Activation (IIS 7+) IIS Metabase and IIS 6 configuration compatibility (IIS 7+) Can anyone point me in the right direction please? Ideally I'm looking for registry values that I can check directly from InstallScript code, but I guess some kind of WMI or COM check would be OK as well. PS: In case it's relevant, we need to support all versions of IIS from 5.1 onwards at this time. If 5.1 support is a problem, we may consider dropping it if we have to.

• Core Data - Relationship to dissimilar entities

  - by carotene

  Suppose I have the following data model: Entity Person Attribute name String Attribute personType String Attribute dailyRecords Entity CarpenterDailyRecord Attribute numberOfNailsHammered Int Attribute picNameOfFinishedCabinet String Entity WindowWasherDailyRecord Attribute nameOfBuildingWashed String Attribute numberOfWindowsWashed Int I would like to establish a to-many relationship between the Person.dailyRecords and 1 of the daily record entities (which changes depending on the person type). Of course, i could create a CarpenterPerson and WindowWasher entity which each points to it's unique daily record structure, but i have to group people together in my app somehow. so if i do a Group Entity: Entity Group Attribute people array i'm still stuck. how do i point to multiple & different Person entities? There must be an obvious answer, it's just i'm so new to all of this. thanks!

• How to change object positions in an android layout?

  - by Pedro Santos

  Hi, I'm currently working on a very simple aplication, and I intended to make it change the visual aspect depending on the screen size. The application just has 6 buttons like this: http://www.freeimagehosting.net/uploads/e1efb4c4d0.jpg I'm using the AbsoluteLayout, and changing the x and y of the buttons with the methods offsetLeftAndRight and offsetTopAndBottom. I'm not changing the layout of the buttons in the xml file, so the all start in the same place. However, if I use this methods inside the onClickMethod they sometimes appear where I want them, sometimes don't (can't figure out why), but if i use them in the onCreate method, nothing happens. Can someone point me in the right direction? Thanks

• VBScript - copy files modified in last 24 hours

  - by Martin North

  Hi, I'm trying to copy files from a directory where the last modified date is within 24hours of the current date. I'm using a wildcard in the filepath as it changes every day I'm using; option explicit dim fileSystem, folder, file dim path path = "d:\x\logs" Set fileSystem = CreateObject("Scripting.FileSystemObject") Set folder = fileSystem.GetFolder(path) for each file in folder.Files If DateDiff("d", file.DateLastModified, Now) < 1 Then filesystem.CopyFile "d:\x\logs\apache_access_log-*", "d:\completed logs\" WScript.Echo file.Name & " last modified at " & file.DateLastModified end if next Unfortunately this seems to be copying all files, and not just the recently modified ones. Can anyone point me in the right direction? many thanks Martin.
