  • ASP.NET MVC Model Binding into a List

    - by Maxim Z.
    In my ASP.NET MVC site, part of a feature allows the user to enter the hours when a certain venue is open. I've decided to store these hours in a VenueHours table in my database, with a FK-to-PK relationship to a Venues table, as well as DayOfWeek, OpeningTime, and ClosingTime parameters. In my View, I want to allow the user to only input the times they know about; in other words, some days may not be filled in for a Venue. I'm thinking of creating checkboxes that the user can check to enable the OpeningTime and ClosingTime fields for the DayOfWeek that the checkbox belongs to. My question relates to how to pass this information to my HttpPost Controller Action. As I know the maximum amount of Days that can be passed in (7), I could of course just write 7 nullable VenueHour parameters into my Action, but I'm sure there's a better way. Can I somehow bind the View information into a List that is passed to my Action? This will also help me if I run into a scenario where there is no limit to how much information the user can fill in.

  • Yahoo Pipes: filter items in a feed based on words in a text file

    - by pufferfish
    I have a pipe that filters an RSS feed and removes any item that contains "stopwords" that I've chosen. Currently I've manually created a filter for each stopword in the pipe editor, but the more logical way is to read these from a file. I've figured out how to read the stopwords out of the text file, but how do I apply the filter operator to the feed, once for every stopword? The documentation states explicitly that operators can't be applied within the loop construct, but hopefully I'm missing something here.

  • Make an iPhone InfoButton light/dark based on color behind it

    - by Paula
    How do I detect what color is under the InfoButton... so I can change the button from DARK to LIGHT? I set my view's color... but how do I tell if it's "kind of light" or "kind of dark"? Besides... I can't change the info-button from light to dark anyway. (read only) Ugh. Shouldn't Apple have some kind of a simple "cmdButton.doThisExtremelyCommonThingForMe = TRUE" statement? InfoButtons are useless if you can't even see them. (Or how would I put an image behind the button to make it stand-out more?)

  • Asp.Net MVC 2: How exactly does a view model bind back to the model upon post back?

    - by Dr. Zim
    Sorry for the length, but a picture is worth 1000 words: In ASP.NET MVC 2, the input form field "name" attribute must contain exactly the syntax below that you would use to reference the object in C# in order to bind it back to the object upon post back. That said, if you have an object like the following where it contains multiple Orders having multiple OrderLines, the names would look and work well like this (case sensitive): This works: Order[0].id Order[0].orderDate Order[0].Customer.name Order[0].Customer.Address Order[0].OrderLine[0].itemID // first order line Order[0].OrderLine[0].description Order[0].OrderLine[0].qty Order[0].OrderLine[0].price Order[0].OrderLine[1].itemID // second order line, same names Order[0].OrderLine[1].description Order[0].OrderLine[1].qty Order[0].OrderLine[1].price However we want to add order lines and remove order lines at the client browser. Apparently, the indexes must start at zero and contain every consecutive index number to N. The black belt ninja Phil Haack's blog entry here explains how to remove the [0] index, have duplicate names, and let MVC auto-enumerate duplicate names with the [0] notation. However, I have failed to get this to bind back using a nested object: This fails: Order.id // Duplicate names should enumerate at 0 .. N Order.orderDate Order.Customer.name Order.Customer.Address Order.OrderLine.itemID // And likewise for nested properties? Order.OrderLine.description Order.OrderLine.qty Order.OrderLine.price Order.OrderLine.itemID Order.OrderLine.description Order.OrderLine.qty Order.OrderLine.price I haven't found any advice out there yet that describes how this works for binding back nested ViewModels on post. Any links to existing code examples or strict examples on the exact names necessary to do nested binding with ILists? Steve Sanderson has code that does this sort of thing here, but we cannot seem to get this to bind back to nested objects. Anything not having the [0]..[n] AND being consecutive in numbering simply drops off of the return object. Any ideas?

  • Problem with stack based implementation of function 0x42 of int 0x13

    - by IceCoder
    I'm trying a new approach to int 0x13 (just to learn more about the way the system works): using stack to create a DAP.. Assuming that DL contains the disk number, AX contains the address of the bootable entry in PT, DS is updated to the right segment and the stack is correctly set, this is the code: push DWORD 0x00000000 add ax, 0x0008 mov si, ax push DWORD [ds:(si)] push DWORD 0x00007c00 push WORD 0x0001 push WORD 0x0010 push ss pop ds mov si, sp mov sp, bp mov ah, 0x42 int 0x13 As you can see: I push the dap structure onto the stack, update DS:SI in order to point to it, DL is already set, then set AX to 0x42 and call int 0x13 the result is error 0x01 in AH and obviously CF set. No sectors are transferred. I checked the stack trace endlessly and it is ok, the partition table is ok too.. I cannot figure out what I'm missing... This is the stack trace portion of the disk address packet: 0x000079ea: 10 00 adc %al,(%bx,%si) 0x000079ec: 01 00 add %ax,(%bx,%si) 0x000079ee: 00 7c 00 add %bh,0x0(%si) 0x000079f1: 00 00 add %al,(%bx,%si) 0x000079f3: 08 00 or %al,(%bx,%si) 0x000079f5: 00 00 add %al,(%bx,%si) 0x000079f7: 00 00 add %al,(%bx,%si) 0x000079f9: 00 a0 07 be add %ah,-0x41f9(%bx,%si) I'm using qemu latest version and trying to read from hard drive (0x80), have also tried with a 4bytes alignment for the structure with the same result (CF 1 AH 0x01), the extensions are present.

  • Weak event handler model for use with lambdas

    - by Benjol
    OK, so this is more of an answer than a question, but after asking this question, and pulling together the various bits from Dustin Campbell, Egor, and also one last tip from the 'IObservable/Rx/Reactive framework', I think I've worked out a workable solution for this particular problem. It may be completely superseded by IObservable/Rx/Reactive framework, but only experience will show that. I've deliberately created a new question, to give me space to explain how I got to this solution, as it may not be immediately obvious. There are many related questions, most telling you you can't use inline lambdas if you want to be able to detach them later: Weak events in .Net? Unhooking events with lambdas in C# Can using lambdas as event handlers cause a memory leak? How to unsubscribe from an event which uses a lambda expression? Unsubscribe anonymous method in C# And it is true that if YOU want to be able to detach them later, you need to keep a reference to your lambda. However, if you just want the event handler to detach itself when your subscriber falls out of scope, this answer is for you.

  • Interface design pattern / Java / Seam

    - by Walter White
    Hi all, Is this possible somehow? @Name("geolocationService") public interface GeolocationService { @Query("SELECT g FROM Geolocation geolocation INNER JOIN geolocation.deployment deployment WHERE geolocation.ipStart <= INET_ATON(:ipAddress) AND deployment.active = TRUE") Geolocation findByIpAddress(@NamedParameter("ipAddress")final String ipAddress); } public GeolocationAction { @In private GeolocationService geolocationService; @RequestParameter("ipAddress") private String ipAddress; @Out private Geolocation geolocation; public void find() { geolocation = geolocationService.findByIpAddress(ipAddress); } } Is it possible to do this without implementing the interface? What is required to make that work? I want to maintain less and do more. If I can intercept invocations of the geolocationService then I am golden, how would I do that? I don't want it to ever be instantiated, so it will always be null (I don't want the @Name and @In annotations either then). Walter

  • Migrating from VisualSVN on windows to linux based svn

    - by Jonathan
    I'd like to migrate my svn repository from my local computer running windows and VisualSVN 2.1.2 to an svn app on webfaction (my Linux hosting solution). Initially I tried dumping the svn: svnadmin dump *path_to_repository* *dumpfile_name* and loading it on the Linux machine svnadmin load *dumpfile_name* I received the following error: svnadmin: Can't open file '*dumpfile_path_and_name*/format': Not a directory I found that on my Windows machine I do have a format folder under the repository. So I copied the entire repository to the Linux machine and tried: svnadmin load *path_to_repository_copy* I received the following error: svnadmin: Expected FS format between '1' and '3'; found format '4' what should I do?

  • Does UIWebView support javascript-based double-click events?

    - by Eric
    As usual, I'm trying to do something the easiest way possible, in this case implement a double-tap handler on a UIWebView like so: <div id="foo" ondblclick="clickHandler(this);" ... > It works fine in Safari and Firefox, and I know the code containing clickHandler is loading on the iPhone thanks to a now-annoying alert stmt at the end of loading. If I change ondblclick to onclick it works on both the device and the simulator. From reading similar queries it would seem that I need to intercept the taps in ... and then run my JavaScript code with the stringByEvaluatingJavaScriptFromString method, but then how do I know the JS id of the target? I no like that, would rather write a pure HTML/DOM/JS solution. Or since my app is about 80% web content, should I be using phonegap instead?

  • Domain driven design value object, how to ensure a unique value

    - by Darren
    Hi, I am building a questionnaire creator. A questionnaire consists of sections, sections consist of pages and pages consist of questions. Questionnaire is the aggregate root. Sections, pages and questions can have what are called shortcodes which should be unique within a questionnaire (but not unique within the database hence they are not strictly an identity). I intended to make the shortcode a value object and wanted to include the business rule that it should be unique within the questionnaire but I am unsure how to ensure that. My understanding is that the value object should not access the repository or service layer so how does it find out if it is unique? Thanks for any help. Darren

  • update variable based upon results from .NET backgroundworker

    - by Bruce
    I've got a C# program that talks to an instrument (spectrum analyzer) over a network. I need to be able to change a large number of parameters in the instrument and read them back into my program. I want to use backgroundworker to do the actual talking to the instrument so that UI performance doesn't suffer. The way this works is - 1) send command to the instrument with new parameter value, 2) read parameter back from the instrument so I can see what actually happened (for example, I try to set the center frequency above the max that the instrument will handle and it tells me what it will actually handle), and 3) update a program variable with the actual value received from the instrument. Because there are quite a few parameters to be updated I'd like to use a generic routine. The part I can't seem to get my brain around is updating the variable in my code with what comes back from the instrument via backgroundworker. If I used a separate RunWorkerCompleted event for each parameter I could hardwire the update directly to the variable. I'd like to come up with a way of using a single routine that's capable of updating any of the variables. All I can come up with is passing a reference number (different for each parameter) and using a switch statement in the RunWorkerCompleted handler to direct the result. There has to be a better way.

  • jqGrid - how to change title based on colModel sortable property

    - by Greg
    When the mouse hovers over each column I'd like the tooltip to indicate whether that column is sortable. I am able to change the title attribute with something like this: $("#List .ui-th-column").each(function(i) { var isSortable = i % 2; $(this).attr('title', isSortable ? "Not Sortable" : "Click header to sort."); }); I'd like to replace the demo expression 'i % 2' with a check of the colMode's sortable property, but I can't figure out how to get the value of the colModel's sortable property. colModel: [ { name: 'Name', index: 'Name', width: 100, sortable: true }, { name: 'Note', index: 'Note', width: 200, sortable: false } ] I've tried .getGridParam and .getColProp but I don't think the syntax I'm using is correct.

  • SQL database problems with addressbook table design

    - by Sebastian Hoitz
    Hello! I am writing a addressbook module for my software right now. I have the database set up so far that it supports a very flexible address-book configuration. I can create n-entries for every type I want. Type means here data like 'email', 'address', 'telephone' etc. I have a table named 'contact_profiles'. This only has two columns: id Primary key date_created DATETIME And then there is a table called contact_attributes. This one is a little more complex: id PK #profile (Foreign key to contact_profiles.id) type VARCHAR describing the type of the entry (name, email, phone, fax, website, ...) I should probably change this to a SET later. value Text (containing the value for the attribute). I can now link to these profiles, for example from my user's table. But from here I run into problems. At the moment I would have to create a JOIN for each value that I want to retrieve. Is there a possibility to somehow create a View, that gives me a result with the type's as columns? So right now I would get something like #profile type value 1 email [email protected] 1 name Sebastian Hoitz 1 website domain.tld But it would be nice to get a result like this: #profile email name website 1 [email protected] Sebastian Hoitz domain.tld The reason I do not want to create the table layout like this initially is, that there might always be things to add and I want to be able to have multiple attributes of the same type. So do you know if there is any possibility to convert this dynamically? If you need a better description please let me know. Thank you!

  • Lightweight PHP5 based template class/system

    - by Wizzard
    Hi there. Looking at using a template system for a new project, it's only a small site and don't want to use the overhead and 'complexity' of smarty. I don't really like template systems that force you to make use of another language just to make it easier for designers (apparently). Something like this http://www.namepros.com/code/517342-php5-template-class.html is what Im looking at but something which is a bit more robust and proven.

  • Best strategy for HTML partial rendering based on multiple dropdown values

    - by pv2008
    I have a View that renders something like this: "Item 1" and "Item 2" are <tr> elements from a table. After the user change "Value 1" or "Value 2" I would like to call a Controller and put the result (some HTML snippet) in the div marked as "Result of...". I have some vague notions of JQuery. I know how to bind to the onchange event of the Select element, and call the $.ajax() function, for example. But I wonder if this can be achieved in a more efficient way in ASP.NET MVC2.

  • How to get child container reference in View Model

    - by niels-verkaart
    Hello, I´m trying to share a Data Service (Entity Manager) wrapped in a Repository from a ViewModel (called 'AVM') in Module A to a ViewModel (called 'BVM') in Module B, and I can't get this working. We use PRISM/Unity 2.0 This is my scenario: A user may open multiple Customer screens (composite view as mini shell) each with another customer (unit of work). We realize this using child containers. Each child container resolves it's own repository with its own Entity manager (the repository is a singleton within the child container). This is done in module A. The main shell has a main region manager, and each Customer screen with its childcontainer creates a scoped region. In each customer screen there is a View 'AV' (connected to ViewModel 'AVM') with a SubRegion (tab control) registered as 'SubRegion'. We create this with a 'Screen Factory' In Module B we have a Customer Orders in View 'BV' and ViewModel 'BVM'. In the constructor of Module B we get the main container by injection. In the initialize method we resolve the (main) region manager and register View 'BV' with it. In the constructor of View 'BV' a ViewModel 'BVM' is injected/created. Now this works, but the ViewModel 'BVM' cannot get the child container. It only get the main container. Is this doable, or do I have to do this another way? Thanks, Niels

  • Multi Action with Form design streatgy

    - by Ravi
    Hello All, I want to have a controller that can handle multiple requests. Like a UserController handling all the addUser, deleteUser, updateUser and viewUser functionality. I know that MultiActionController can be used to bundle multiple similar request into one controller. But the functionalities like addUser and updateUser involves user to enter data, which the controller need to process. Can a MultiActionController handle doSubmit kind of methods (similar to SimpleFormController). Is there any better way to handle this kind of scenario? Thanks. Ravi
