  • set variables in an MVC application?

    - by Melissa
    I am trying to learn about the Orchard MVC application. I see the following code but cannot understand what it is doing. Can someone explain what this: User.As<UserPart>().Record.UserName = value; means? public class UserEditViewModel { [Required] public string UserName { get { return User.As<UserPart>().Record.UserName; } set { User.As<UserPart>().Record.UserName = value; } } [Required] public string Email { get { return User.As<UserPart>().Record.Email; } set { User.As<UserPart>().Record.Email = value; } } public IContent User { get; set; } }

  • NSString simple pattern matching

    - by SirRatty
    Hi all, Mac OS 10.6, Cocoa project, 10.4 compatibility required. (Please note: my knowledge of regex is quite slight) I need to parse NSStrings, for matching cases where the string contains an embedded tag, where the tag format is: [xxxx] Where xxxx are random characters. e.g. "The quick brown [foxy] fox likes sox". In the above case, I need to grab the string "foxy". (Or nil if no tag is found.) Each string will only have one tag, and the tag can appear anywhere within the string, or may not appear at all. Could someone please help with a way to do that, preferably without having to include another library such as RegexKit. Thank you for any help.

  • php simplexmlelement get first element in one line

    - by Senica Gonzalez
    Just trying to figure a shorter way to do this: I'm using simpleXMLElement to parse an xml file and it's aggravating to have to call two lines to process an array when I know what node I want. Current code: $xml = new SimpleXMLElement($data); $r = $xml->xpath('///givexNumber'); $result["cardNum"] = $r[0]; What I would like to do would be something like I can do with DomX $result["cardNum"] = $xml->xpath('///givexNumber')->item(0)->nodeValue; Any ideas? I didn't really see that simplexmlelement can do this, but thought someone might know a trick or two.

  • unicode data with custom font doesn't work properly in ipad

    - by David Ohanyan
    I am using custom font for label and string which I am getting from unicode characters. And the font is not changing. here is the snippet of my code: NSString* str = @"\u05D0\u05D1\u05D2"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; But when I write for example : NSString* str = @"label"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; The font effect is evident. Can someone explain what's here wrong?

  • Identifying CDs

    - by Chris
    I'd like to be able to determine what music album CD is in a CD drive. For example, if someone claims that the CD in their drive is Eminem - The Eminem Show, I would like to be able to verify that the CD is indeed The Eminem Show. Any ideas? I've applied for a Gracenote developer license, but they won't get back to me for five days. Also, how does this work? Is there some GUID or other unique identifier that music discs are encoded with? Lastly, might this be possible with data CDs, like, say, the Diablo II install Disc 1? If so, any directions you can point me in, for accomplishing this?

  • How can I make a read only version of a class?

    - by Eric
    I have a class with various public properties which I allow users to edit through a property grid. For persistence this class is also serialized/deserialized to/from an XML file through DataContractSerializer. Sometimes I want to user to be able to save (serialize) changes they've made to an instance of the class. Yet at other times I don't want to allow the user to save their changes, and should instead see all the properties in the property grid as read only. I don't want to allow users to make changes that they'll never be able to save later. Similar to how MS Word will allow users to open documents that are currently opened by someone else but only as read only. My class has a boolean property that determines if the class should be read-only, but is it possible to use this property to somehow dynamically add a read-only attributes to the class properties at run-time? If not what is an alternative solution? Should I wrap my class in a read-only wrapper class?

  • Unique keys for Sphinx along three vectors instead of two

    - by Brendon Muir
    I'm trying to implement thinking-sphinx across multiple 'sites' hosted under a single rails application. I'm working with the developer of thinking-sphinx to sort through the finer details and am making good progress, but I need help with a maths problem: Usually the formula for making a unique ID in a thinking-sphinx search index is to take the id, multiply it by the total number of models that are searchable, and add the number of the currently indexed model: id * total_models + current_model This works well, but now I also through an entity_id into the mix, so there are three vextors for making this ID unique. Could someone help me figure out the equation to gaurantee that the id's will never collide using these three variables: id, total_models, total_entities The entity ID is an integer. I thought of: id * (total_models + total_entities) + (current_model + current_entity) but that results in collisions. Any help would be greatly appreciated :)

  • StockTrader RI > Controllers, Presenters, WTF?

    - by SandRock
    I am currently learning how to make advanced usage of WPF via the Prism (Composite WPF) project. I watch many videos and examples and the demo application StockTraderRI makes me ask this question: What is the exact role of each of the following part? SomethingService: Ok, this is something to manage data SomethingView: Ok, this is what's displayed SomethingPresentationModel: Ok, this contains data and commands for the view to bind to (equivalent to a ViewModel). SomethingPresenter: I don't really understand it's usage SomethingController: Don't understand too I saw that a Presenter and a Controller are not necessary but I would like to understand why they are here. Can someone tell me their role and when to use them?

  • C# timer getting fired before their interval time

    - by Swati Ghaisas
    Hi, We're getting following problem while using system.threading.timer ( .net framework 2.0 ) from a Windows service. There are around 12 different timer objects.. Each timer has due time and interval. This is set correctly. It is observed that after 3 to 4 hours, the timers start signalling before their interval elapses. For example if the timer is supposed to signal at 4:59:59, it gets signalled at 4:59:52, 7 seconds earlier. Can someone tell me what is the cause for this behavior and what is the solution for that ? Thanks, Swati

  • Refreshing an XML file through HTTPService in Flex

    - by pfunc
    I'm having a problem refreshing an xml file. I am bringing it in through an HTTP service component and putting it into a bindable array _cattArr, that I am using as the dataprovider for a grid. When someone adds an item to the datagrid, it saves to the same xml file. Then I close the window, reopen it and don't see the item that has been added. It is writing to the xml file, because when I restart the flex app, the item has been added, it's just not refreshing it. I have tried to resend the httpservice, but still no luck. What is the correct process for doing this?

  • detect page refresh jQuery or C# ASP.Net

    - by Marco
    Hello, I was searching for a way of detecting in my C# code if the page had been refreshed (f5). First I don’t know if a jQuery/JavaScript solution would be better than a fully C# ASP.Net. So... the first question would be: What would make you choose one over the other? And the third, and most important part, is if someone would help me with this. Some good tutorial, or article… anything. I tried some solutions out there… but maybe, because of my lack of knowledge they didn’t work. Thanks in advance.

  • How do I overlay an icon/image onto another image on form submission?

    - by marcamillion
    So I am trying to add an icon to an image, once someone has 'tagged' a portion of the image - i.e. they have submitted the form. How do I do that in jQuery? Just to be clear...imagine you are on flickr and you see an image. You want to add an annotation, you click on the image where you want, and it shows you a form field. You enter the information you want to, then after you have done so, there is a small image left on top of the picture that shows where you have left a comment. Any ideas?

  • XSS as attack vector even if XSS data not stored?

    - by Klaas van Schelven
    I have a question about XSS Can forms be used as a vector for XSS even if the data is not stored in the database and used at a later point? i.e. in php the code would be this: <form input="text" value="<?= @$_POST['my_field'] ?>" name='my_field'> Showing an alert box (demonstrate that JS can be run) on your own browser is trivial with the code above. But is this exploitable across browsers as well? The only scenario I see is where you trick someone into visiting a certain page, i.e. a combination of CSRF and XSS. "Stored in a database and used at a later point": the scenario I understand about CSS is where you're able to post data to a site that runs JavaScript and is shown on a page in a browser that has greater/different privileges than your own. But, to be clear, this is not wat I'm talking about above.

  • Why do I get a "Day too big" error from Perl?

    - by azp74
    I have been helping someone debug some code where the error message was "Day too big". I know that this springs from localtime and the Y2038 bug (most google results appear to be people dealing with cookies expiring well into the future). We appear to have 'fixed' the problem by using time to get the current date. However, given that none of our original dates should have hit the 2038 issue I'm sceptical that we've actually fixed the problem ... Are there other instances that anyone knows of where one would hit "day too big"? OS is Solaris. Sample code - the actual code is quite large and the person I'm working with hasn't actually isolated the offending part (which is why I'm worried the 'fix' is not actually a fix). If I can put together something concise which reproduces the issue I will post!

  • How to connect to the database in Magento?

    - by Click Upvote
    I'm trying to build a simple Magento Module that needs to connect to the database at the start of each page request. All tables need to be accessible to it. I've been pulling my hair out trying to understand how to do it. The best I could figure out was that I need to set this in the config.xml file of my module, but exactly what that command is/how it may be used, i haven't been able to figure out. Can someone please guide me or show me how to accomplish this? If not, would it be too bad a practice to include a custom config.php file which connects to the database manually?

  • Flex / ZendAMF / PHP app, corrupted data with some linux clients problem

    - by Laurent Jégou
    Hello, i'm buiding a survey web application, using Flex for the front-end (nice forms), and a MySQL database for the storage, linked by PHP with the help of ZendAMF. I largely borrowed from this nice tutorial by Alan Gruskoff : http://digitalshowcase.biz/wordpress/?page_id=26 (The only one tutorial i've found to work with the last version of Flex). The app seems to works nicely in my tests, except on certain linux boxes : the data is somehow corrupted : there is no error message, no glitch, but the response of the forms are not what the user selected. I tried to reproduce the error on a fresh installed ubuntu VM, but it works fine. I've asked friends for some tests, and several linux users showed the same problem, on ubuntu and suse machines, all freshly updated and functionnal. The application was targeted to be the survey tool for my doctoral thesis, so i'm quite desperate here, and before i'm dumping it to start anew with php only, i'm asking here in case someone can help, thanks :-) Please excuse my english, by the way. LJ.

  • Matlab code help. Backward Euler method.

    Here is the matlab/freemat code I got to solve ODE numerically using backward Euler method.

  • What is the purpose of Java's unary plus operator?

    - by Syntactic
    Java's unary plus operator appears to have come over from C, via C++. As near as I can tell, it has the following effects: promotes its operand to int, if it's not already an int or wider unboxes its operand, if it's a wrapper object complicates slightly the parsing of evil expressions containing large numbers of consecutive plus signs It seems to me that there are better (or, at least, clearer) ways to do all of these things. In this SO question, concerning the counterpart operator in C#, someone said that "It's there to be overloaded if you feel the need." But in Java, one cannot overload any operator. So does this operator exist in Java just because it existed in C++?

  • XML, XPATH adding values

    - by user575373
    hello, i have XML files which contain records with the following structure: <payment contractType="1"> <income type="0"> <gr code="1" amount="1506.00"/> <gr code="4" amount="35.00"/> <gr code="10" amount="288.14"/> <de code="3011300" amount="138.72"/> <de code="3081100" amount="48.81"/> <de code="3082400" amount="109.84"/> </income> <netAmount1 value="765.00"/> <netAmount2 value="765.00"/> </payment> each file has many records of type payment and i want the final xml to contain one payment record by adding all the amount values for every differrent code value I think XPath can be used for this, but I never used it before , could someone show me some Java (or else) code for this?

  • Any form autofill for 'Developers'?

    - by Majid
    Hi all, I have looked at some autofills for Firefox. But they are not designed with the developers' needs in mind. General internet surfers will need a tool to fill in many different forms with constant values for each form. Developers need exactly the opposite, when you want to test a part of your app you'll need to fill a single (or a couple of) forms many times with different (but valid and sensible) data. So, does such a thing exist? An autofill to fill form inputs based on perhaps a class name (email, password, address, url, ...)? I strongly feel if it doesn't exist someone should roll up their sleeves and make one! I for one will put in my share if some others want to team up. But right now, I am desperately in need of one if it exists

  • How to structure a multilingual website for search engines?

    - by Nirmal
    I have this website which decides on the display language by a GET parameter. http://www.mysite.com/index.php?page=home&locale=en which is rewritten as http://www.mysite.com/en/home When no language is specified, the system defaults to English (en). Now how do I tell the search engines that many versions of the website exist? When the search bot enters the site, it will trigger the default English Language and after finishing, will just leave the site without considering other languages. I can very well have a sitemap with links to the default pages of each language, so the bot can navigate from there. But how do I say the bot that the entry in the sitemap is the home page for that language? Like if someone searches for 'mi sitio', they should be presented with the result http://www.mysite.com/es/home and not some other internal page. Any light on this? Thanks.
