• Stop sign icon in VS2005 Express solution explorer

  - by Andy Bisson

  What does a small stop sign icon on a file in solution explorer mean? Someone asked the same question a year ago Original Question but the answer provided is of no help. The icon looks like this: Suffice to say that the sign is not one presented in the VS documentation and is a UK Stop sign (red circle with a white horizontal bar) not a US one. The project is WebKit and the build process cannot find AuthenticationCF.h even though the file is present. I presume the sign might shed some light on this. Thanks, Andy

• Is Catching a Null Pointer Exception a Code Smell?

  - by Drew

  Recently a co-worker of mine wrote in some code to catch a null pointer exception around an entire method, and return a single result. I pointed out how there could've been any number of reasons for the null pointer, so we changed it to a defensive check for the one result. However, catching NullPointerException just seemed wrong to me. In my mind, Null pointer exceptions are the result of bad code and not to be an expected exception in the system. Are there any cases where it makes sense to catch a null pointer exception?

• ReportViewr: Hyperlink to a local file doesn't work

  - by kernelMode

  I need to add 2 type of links to existing report with c#. For exapmle: 1) http://www.google.co.il/ 2) file:///C:/index.html I added the links, but only the "http://" works. when I press the link of "file:///" nothing happens. I've uploaded the full project (very small though) which includes the problem: http://www.filefactory.com/file/452gsoyymalv/n/ObjectReports.zip btw, The "index.html" is a simple 'helloWorld' which loaded successfully when writing the path on the address bar in the browser. Do anyone know what additional settings should be set to make the link work? Thanks!!!

• Address Validation API

  - by Paul

  I have a task to validate addresses entered into a system I am currently creating. The system requires that address entered are validated against a valid data source. In the UK the dataset comes from the Royal Mail and is expensive to access. The data needed is post code info for the whold of europe to start with accessed by an API into the web application. There are a number of companies that offer this service, QAS Capscan Postcode anywhere These all offer the service I require. However this is expensive and in some cases not a complete data set. e.g. not Ireland I was also wondering if there would be a way to utalis the google maps API to validate this data via postal code and country. Would the google maps method be possible or do I have to go down the line of one of these expensive companies? Any thoughts on what line I should take.

• Iframe auto-height not working when page changes in IE

  - by DisgruntledGoat

  I have an iframe in a page, with the following auto-height script. function autoHeight(e) { if ( e.contentDocument ) { e.height = e.contentDocument.body.offsetHeight + 35; } else { e.height = e.contentWindow.document.body.scrollHeight + 35; } } document.domain = "totalstudents.co.uk"; var ifr = document.getElementById('housingdata'); ifr.onload = function() { autoHeight(ifr); } The iframe resizes fine when the outer page is loaded, but when I go to a new page in the iframe, scrollbars appear and the page does not get resized in Internet Explorer. In other browsers the iframe gets resized, because the onload event fires each time. I'm using IE8 but the outer page is setting it to IE7 compatibility mode. Is there a workaround for IE?

• c# Dynamically generated controls issue.

  - by Thomas

  Good Day I have a form with a panel docked in it. I then dynamically create 15 panels (named: panel_n) and 15 pictureboxes (named: picturebox_n) on the primary panel (named ContainerPanel). When dragging the any picturebox over a panel (panel_n) created using the relevant mouse events. I would like to get the panel's name that the picture box was dragged over. The mouse cursor seems to be captured. I have tried creating a IMessageFilter interface, but there are still no events that trigger when dragging one of the pictureboxes over any one of the panels. The ClientRectangle.IntersectsWith function also does not work as the co-ords are always 0,0. All I need is the panel name where the picturebox was dragged over (preferably on the mouseup event)

• StaX: Content not allowed in prolog

  I have the following (test) XML file below and Java code that uses StaX.

• JPQL: What kind of objects contains a result list when querying multiple columns?

  - by Bunkerbewohner

  Hello! I'm trying to do something which is easy as pie in PHP & Co: SELECT COUNT(x) as numItems, AVG(y) as average, ... FROM Z In PHP I would get a simple array like [{ numItems: 0, average: 0 }] which I could use like this: echo "Number of Items: " . $result[0]['numItems']; Usually in JPQL you only query single objects or single columns and get Lists types, for example List or List. But what do you get, when querying multiple columns?

• Finding cities close to one another using longitude and latitude

  - by Jamie

  Each user in my db is associated to a city (with it's longitude and latitude) How would I go about finding out which cities are close to one another? i.e. in England, Cambridge is fairly close to London. So If I have a user who lives in Cambridge. Users close to them would be users living in close surrounding cities, such as London, Hertford etc. Any ideas how I could go about this? And also, how would I define what is close? i.e. in the UK close would be much closer than if it were in the US as the US is far more spread out. Ideas and suggestions. Also, do you know any services that provide this sort of functionality? Thanks

• Rails + simple role system through associative table

  - by user202411

  So I have the Ninja model which has many Hovercrafts through ninja_hovercrafts (which stores the ninja_id and the hovercraft_id). It is of my understanding that this kind of arrangement should be set in a way that the associative table stores only enough information to bind two different classes. But I'd like to use the associative table to work as a very streamlined authorization hub on my application. So i'd also like this table to inform my system if this binding makes the ninja the pilot or co-pilot of a given hovercraft, through a "role" field in the table. My questions are: Is this ugly? Is this normal? Are there methods built into rails that would help me to automagically create Ninjas and Hovercrafts associations WITH the role? For exemple, could I have a nested form to create both ninjas and hcs in a way that the role field in ninjas_hovercrafts would be also filled? If managing my application roles this way isn't a good idea, whats the non-resource heavy alternative (my app is being designed trying to avoid scalability problems such as excessive joins, includes, etc) thank you

  I have a rails backend and am testing the following jquery code against it: var content = $("#notification_content").val(); var data = new Object(); data.content = content; $.ajax({ url: "/notifications/detect_type.json", type:"POST", data: data, success: function(result ){updateTypeDropDown(result)}}); This code works fine in Chrome and IE.

• Full coordinates across streets with google maps

  - by nbv4

  If you go here: http://econym.org.uk/gmap/snap.htm there are some examples of the kind of stuff I'm trying to do. I want the user to enter a route on a google maps widget, and then have the map drawl the route along roads. Then the user click on a "submit" button, and their route is sent back to the server where it will be stored in a database. Instead of sending back just the red vertices, I want to send back all the information that makes up the purple lines. Is this possible?

• Would you hire a foreigner ? [closed]

  - by user229999

  Hi! I'd like to dedicate this question (hope it's not a subjective) especially to people who own their companies. Would you (and why) hire a foreigner, which experience is documented in CV and portfolio, which can communicate in english (with grammar mistakes, but still)? I am writing in the name of all these guys looking for great opportunities abroad, living in countries which do not give you any opportunities at all. Is it real, to be hired like a programmer (PHP, Ruby, Python, C#) in country like UK, USA, Nederland, Sweeden or even Germany, if you're a foreigner? Please response in two categories: a) foreigner with engineer degree, zend certificate, few open source projects b) foreigner without any degree, with nice portfolio, and few big projects created Also, does First Certificate in English aka FCE matter for you ?

• What are the other new features of C# 4.0, after dynamic and optional parameters?

  - by Abel

  So, C# 4.0 came out yesterday. It introduced the much-debated dynamic keyword, named and optional parameters. Smaller improvements were the implicit ref and recognizing of indexed and default properties on COM methods, contra- and co-variance (really a .NET CLR feature, not C# only) and... Is that really it? Are dynamic and optional/named params the only real improvements to C#? Or did I miss something? Not that I'm complaining, but it seems a bit meager after C# 2.0 (generics) and C# 3.0 (lambda, LINQ). Maybe the language just reached actual maturity?

• What's the best way to set cursor/caret position?

  - by Daniel Bachhuber

  If I'm inserting content into a textarea that TinyMCE has co-opted, what's the best way to set the position of the cursor/caret? I'm using tinyMCE.execCommand("mceInsertRawHTML", false, content); to insert the content, and I'd like set the cursor position to the end of the content. Both document.selection and myField.selectionStart won't work for this, and I feel as though this is going to be supported by TinyMCE (through something I can't find on their forum) or it's going to be a really ugly hack. Later: It gets better; I just figured out that, when you load TinyMCE in WordPress, it loads the entire editor in an embedded iframe. Later (2): I can use document.getElementById('content_ifr').contentDocument.getSelection(); to get the selection as a string, but not a Selection Object that I can use getRangeAt(0) on. Making progress little by little.

• Re-ordering a collection of UIView's based on their CGPoint

  - by Chris

  Hi all, I have a NSMutableArray that holds a collection of UIViewControllers Amongst other properties and methods an instance of each of the viewControllers are placed in a parent view The user will place these objects individually when desired to. So essentially I use - (void)addSubview:(UIView *)view when a new view is added to the parent view controller. Because the UI is isometric it's made things a tad more complicated What I am trying to do is re-order the views based on their co-ordinate position, so items higher up the parent UIView frame is indexed lower then views lower in the parent UIview frame. And items that are on the left side of the view are positioned at a higher index to those on the right I think the solution may have to do with re-ordering the NSMutableArray but how can I compare the CGpoints? Do I need to compare the x and y separately?

• CaptureCameraDialog returns OK but does not save (Motorola ES400)

  - by Dominic

  Ok it seems like everyone in the world has issues with CaptureCameraDialog. In my case the result is OK, but when taking the photo there is a MessageBox that says "Error" that appears and disappears in the blink of an eye, then returns to my app (so I don't have time to actually read the error). It has not saved the file. It does not throw an error to my application. There is also another issue which is exactly the same as the issue talked about here (yet none of the fixes work for me). http://www.pcreview.co.uk/forums/thread-4025602.php Does anyone know how to get the "error message" that the dialogue box displays for an instant?
