  • Use jQuery to get values of dropdownlists in an html table column for each row

    - by Arnold
    Hi All, I have a requirement to build a simple html table of memos. The table consists of n-rows each with 2 columns: (1) a dropdownlist of types of memos and (2) the text of a memo - a textbox. I have successfully implemented jQuery to allow the user to Add a new row. That entails the selecting of a type of memo and then typing something into the textbox. I've also implemented jQuery to allow the user to mark a memo row for deletion. This is a partial view and the Save is handled by a container page. Requirements stipulate that there can be only one type of memo in the table. What I would like to be able to do is this: When the user clicks the Add button to add a new row (after having selected the memo type and entered some text into the textbox) I want the code to first examine each row in the table getting the value for each memo type dropdownlist. If the newly entered dropdownlist value is the same as one previously entered, I want to abort the add row process. Requirements also stipulate that all dropdownlists remain enabled to allow the user to change the memo type at any time. Similarly, I would like to be able to scan the table checking to see if that same memo type has already been entered. What would the jQuery look like for this kind of validation? Thanks! Arnold

  • best practice for boolean REST results

    - by Andrew Patterson
    I have a resource /system/resource And I wish to ask the system a boolean question about the resource that can't be answered by processing on the client (i.e I can't just GET the resource and look through the actual resource data - it requires some processing on the backend using data not available to the client). eg /system/resource/related/otherresourcename I want this is either return true or false. Does anyone have any best practice examples for this type of interaction? Possibilities that come to my mind: use of HTTP status code, no returned body (smells wrong) return plain text string (True, False, 1, 0) - Not sure what string values are appropriate to use, and furthermore this seems to be ignoring the Accept media type and always returning plain text come up with a boolean object for each of my support media types and return the appropriate type (a JSON document with a single boolean result, an XML document with a single boolean field). However this seems unwieldy. I don't particularly want to get into a long discussion about the true meaning of a RESTful system etc - I have used the word REST in the title because it best expresses the general flavour of system I am designing (even if perhaps I am tending more towards RPC over the web rather than true REST). However, if someone has some thoughts on how a true RESTful system avoids this problem entirely I would be happy to hear them.

  • Custom listbox sorting

    - by Arcadian
    I need to sort the data contained within a number of listboxes. The user will be able to select between two different types of sorting using radio boxes, one of which is checked by default on form load. I have created the IF statements needed in order to test whether the checked condition is true for that radio button. but i need some help to create the custom sort algorithms. Each list with contain similar looking data, the only difference in the prefix with which each line starts. For example each line in the first listbox starts with the prefix "G30" and the second listbox will be "G31" and so on. There are 10 listboxes in total (G30-G39 in terms of prefixes). The first search algorithm has to sort the lines by the number order of the first 13 chars. Example: This is how the data looks before sorting G35:45:58:11 JG07 G35:45:20:41 JG01 G35:58:20:21 JG03 G35:66:22:20 JG05 G35:45:85:21 JG02 G35:64:56:11 JG03 G35:76:35:11 JG02 G35:77:97:12 JG03 G35:54:29:11 JG01 G35:55:51:20 JG01 G35:76:24:20 JG06 G35:76:55:11 JG01 and this is how it should look after sorting G35:45:20:41 JG01 G35:45:58:11 JG07 G35:45:85:21 JG02 G35:54:29:11 JG01 G35:55:51:20 JG01 G35:58:20:21 JG03 G35:64:56:11 JG03 G35:66:22:20 JG05 G35:76:24:20 JG06 G35:76:35:11 JG02 G35:76:55:11 JG01 G35:77:97:12 JG03 as you can see, the prefixes are the same. so it is sorted, lowest first, by the next pair integers, then the next pair and the next but not by the value after "JG". the second sort algorithm will ignore the first 13 chars and sort by order of the value after "JG", highest first. any help? theres some rep in it for you :) thanks in advance

  • How do I correctly use Unity to pass a ConnectionString to my repository classes?

    - by GenericTypeTea
    I've literally just started using the Unity Application Blocks Dependency Injection library from Microsoft, and I've come unstuck. This is my IoC class that'll handle the instantiation of my concrete classes to their interface types (so I don't have to keep called Resolve on the IoC container each time I want a repository in my controller): public class IoC { public static void Intialise(UnityConfigurationSection section, string connectionString) { _connectionString = connectionString; _container = new UnityContainer(); section.Configure(_container); } private static IUnityContainer _container; private static string _connectionString; public static IMovementRepository MovementRepository { get { return _container.Resolve<IMovementRepository>(); } } } So, the idea is that from my Controller, I can just do the following: _repository = IoC.MovementRepository; I am currently getting the error: Exception is: InvalidOperationException - The type String cannot be constructed. You must configure the container to supply this value. Now, I'm assuming this is because my mapped concrete implementation requires a single string parameter for its constructor. The concrete class is as follows: public sealed class MovementRepository : Repository, IMovementRepository { public MovementRepository(string connectionString) : base(connectionString) { } } Which inherits from: public abstract class Repository { public Repository(string connectionString) { _connectionString = connectionString; } public virtual string ConnectionString { get { return _connectionString; } } private readonly string _connectionString; } Now, am I doing this the correct way? Should I not have a constructor in my concrete implementation of a loosely coupled type? I.e. should I remove the constructor and just make the ConnectionString property a Get/Set so I can do the following: public static IMovementRepository MovementRepository { get { return _container.Resolve<IMovementRepository>( new ParameterOverrides { { "ConnectionString", _connectionString } }.OnType<IMovementRepository>() ); } } So, I basically wish to know how to get my connection string to my concrete type in the correct way that matches the IoC rules and keeps my Controller and concrete repositories loosely coupled so I can easily change the DataSource at a later date.

  • Accessing Static Methods on a Generic class in c#

    - by mrlane
    Hello, I have the following situation in code, which I suspect may be a bit dodgey: I have a class: abstract class DataAccessBase<T> : IDataAccess where T : AnotherAbstractClass This class DataAccessBase also has a static factory method which creates instances of derived classes of itself using an enum value in a which statement to decide which derived type to create: static IDataAccess CreateInstance(TypeToCreateEnum) Now, the types derived from DataAccessBase<T> are themselves NOT generic, they specify a type for T: class PoLcZoneData : DataAccessBase<PoLcZone> // PoLcZone is derived from AnotherAbstractClass So far I am not sure if this is pushing the limits of good use of generics, but what I am really concerned about is how to access the static CreateInstance() method in the first place: The way I am doing this at the moment is to simply pass any type T where T : AnotherAbstractClass. In particular I am passing AnotherAbstractClass itself. This allows compilation just fine, but it does seem to me that passing any type to a generic class just to get at the statics is a bit dodgey. I have actually simplified the situation somewhat as DataAccessBase<T> is the lower level in the inheritance chain, but the static factory methods exists in a middle tier with classes such as PoLcZoneData being the most derived on the only level that is not generic. What are peoples thoughts on this arrangement?

  • C# - parse content away from structure in a binary file

    - by Jeff Godfrey
    Using C#, I need to read a packed binary file created using FORTRAN. The file is stored in an "Unformatted Sequential" format as described here (about half-way down the page in the "Unformatted Sequential Files" section): http://www.tacc.utexas.edu/services/userguides/intel8/fc/f_ug1/pggfmsp.htm As you can see from the URL, the file is organized into "chunks" of 130 bytes or less and includes 2 length bytes (inserted by the FORTRAN compiler) surrounding each chunk. So, I need to find an efficient way to parse the actual file payload away from the compiler-inserted formatting. Once I've extracted the actual payload from the file, I'll then need to parse it up into its varying data types. That'll be the next exercise. My first thoughts are to slurp up the entire file into a byte array using File.ReadAllBytes. Then, just iterate through the bytes, skipping the formatting and transferring the actual data to a second byte array. In the end, that second byte array should contain the actual file contents minus all the formatting, which I'd then need to go back through to get what I need. As I'm fairly new to C#, I thought there might be a better, more accepted way of tackling this. Also, in case it's helpful, these files could be fairly large (say 30MB), though most will be much smaller...

  • ASP.NET MVC PartialView generic ModelView

    - by Greg Ogle
    I have an ASP.NET MVC application which I want to dynamically pick the partial view and what data gets passed to it, while maintaining strong types. So, in the main form, I want a class that has a view model that contains a generically typed property which should contain the data for the partial view's view model. public class MainViewModel<T> { public T PartialViewsViewModel { get; set; } } In the User Control, I would like something like: Inherits="System.Web.Mvc.ViewUserControl<MainViewModel<ParticularViewModel>>" %> Though in my parent form, I must put Inherits="System.Web.Mvc.ViewPage<MainViewModel<ParticularViewModel>>" %> for it to work. Is there a way to work around this? The use case is to make the user control pluggable. I understand that I could inherit a base class, but that would put me back to having something like a dictionary instead of a typed view model.

  • How to change type of information for a Title column in SharePoint MOSS 2007 List?

    - by Ruba
    I created a calendar in SharePoint MOSS 2007 that is connected to my Outlook. I added a custom column “Person” to this list and the type of information in this column is: Person or Group. In SharePoint I can hide Title column and in Calendar View show this Person field as Month View Title. So I can see on the calendar who is working that day. Problem is in Outlook. It seems like Outlook doesn’t know a thing about custom fields. In Outlook I can see only Title and few other fields. I could rename Title field to Person, but I can’t change type of information that it contains. By default it is text field and no way to change it to Person or Group. If I could change those “default” column types, then I think my problem would be solved. I know it is possible. I created a custom list, but this list has also those “sticky” Title, Created By and Modified By columns that can’t be changed or removed. Maybe I have to create a custom list with some other program or code? Please help! Thanks in advance!

  • EF4 and multiple abstract levels

    - by Cedric
    I need to use inheritance with EF4 and the TPH model created from DB. I created a new projet to test simples classes. There is my class model: There is my table in SQL SERVER 2008 : VEHICLE ID : int PK Owner : varchar(50) Consumption : float FirstCirculationDate : date Type : varchar(50) Discriminator : varchar(10) I added a condition in my EDMX on the Discriminator field to differentiate the Scooter, Car, Motorbike and Bike entities. MotorizedVehicle and Vehicle are Abstract. But when I compile, this error appears : Error 3032: Problem in mapping fragments starting at lines 78, 85:EntityTypes EF4InheritanceModel.Scooter, EF4InheritanceModel.Motorbike, EF4InheritanceModel.Car, EF4InheritanceModel.Bike are being mapped to the same rows in table Vehicle. Mapping conditions can be used to distinguish the rows that these types are mapped to. Edit : To Ladislav : I try it and error change to become it for all of my entities : Error 3034: Problem in mapping fragments starting at lines 72, 86:An entity is mapped to different rows within the same table. Ensure these two mapping fragments do not map two groups of entities with overlapping keys to two distinct groups of rows. To Henk (with Ladislay suggestion) : There are all of mappings details : What's wrong ? Thanks

  • How to deal with multiple sub-type of one super-type in Django admin

    - by Henri
    What would be the best solution for adding/editing multiple sub-types. E.g a super-type class Contact with sub-type class Client and sub-type class Supplier. The way shown here works, but when you edit a Contact you get both inlines i.e. sub-type Client AND sub-type Supplier. So even if you only want to add a Client you also get the fields for Supplier of vice versa. If you add a third sub-type , you get three sub-type field groups, while you actually only want one sub-type group, in the mentioned example: Client. E.g.: class Contact(models.Model): contact_name = models.CharField(max_length=128) class Client(models.Model): contact = models.OneToOneField(Contact, primary_key=True) user_name = models.CharField(max_length=128) class Supplier(models.Model): contact.OneToOneField(Contact, primary_key=True) company_name = models.CharField(max_length=128) and in admin.py class ClientInline(admin.StackedInline): model = Client class SupplierInline(admin.StackedInline): model = Supplier class ContactAdmin(admin.ModelAdmin): inlines = (ClientInline, SupplierInline,) class ClientAdmin(admin.ModelAdmin): ... class SupplierAdmin(admin.ModelAdmin): ... Now when I want to add a Client, i.e. only a Client I edit Contact and I get the inlines for both Client and Supplier. And of course the same for Supplier. Is there a way to avoid this? When I want to add/edit a Client that I only see the Inline for Client and when I want to add/edit a Supplier that I only see the Inline for Supplier, when adding/editing a Contact? Or perhaps there is a different approach. Any help or suggestion will be greatly appreciated.

  • Parsing a complicated HTML table with PHP

    - by user2944979
    I successfully parsed a dynamic table with the following PHP code: $docH = new DOMDocument(); $docH->loadHTMLFile($url); //get everything inside the body element: $bodyH = $docH->getElementsByTagName('body')->item(0); foreach ($bodyH->childNodes as $childNode) { echo $docH->saveHTML($childNode); } Parsed HTML Table: <table> <tr> <td>5CG </td> <td>aass </td> <td>sxs </td> <td>sx </td> <td>EK </td> <td> </td> <td>72 </td> </tr> <td> </td> <td>samplxs </td> <td>xs </td> <td> </td> <td>xss </td> <td>fkxsx aus</td> <td>s </td> </tr> <td> </td> <td>5AH. </td> <td>ds </td> <td>d </td> <td>sdf </td> <td>sdfsdf aus</td> <td> </td> </tr> <tr> <td>6CG </td> <td>3. </td> <td>sfd </td> <td> </td> <td>scs </td> <td>das aus</td> <td>a </td> </tr> <tr> <td>7DG </td> <td>6. </td> <td>s </td> <td>s </td> <td>sD </td> <td>sdsa.</td> <td> </td> </tr> <td> </td> <td>samplxs </td> <td>xs </td> <td> </td> <td>xss </td> <td>fkxsx aus</td> <td>s </td> </tr> <tr> <td>7DG, 7CG, 7CR </td> <td>6. </td> <td>NsdR </td> <td>s </td> <td>SP </td> <td>fasdlt aus</td> <td>s </td> </tr> <td> </td> <td>samplxs </td> <td>xs </td> <td> </td> <td>xss </td> <td>fkxsx aus</td> <td>s </td> </tr> <tr> <td> 9BR </td> <td>6. </td> <td>FEI </td> <td>sa </td> <td>DE </td> <td>fasdad aus</td> <td> </td> </tr> <tr> <td>9AR, 9BR, 9CR</td> <td>62. </td> <td>BEH </td> <td> </td> <td>sd </td> <td>fasda aus</td> <td> </td> </tr> <tr> <td> </td> <td>6. </td> <td>MLR </td> <td> </td> <td>FdR </td> <td>fsdfaus</td> <td> </td> </tr> <tr> <td>E10C </td> <td>6. </td> <td>sdf </td> <td>d </td> <td>d </td> <td>fsdfs aus</td> <td> </td> </tr> <tr> </table> But my goal is to just show the content of the table the user wants by asking for just the <tr> elements in which the first <td> of the first <tr> includes some text until there is another <tr> which first <td> has a different content. For example: If the user types "9BR" into an input field, I just want him to see: <td> 9BR </td> <td>6. </td> <td>FEI </td> <td>sa </td> <td>DE </td> <td>fasdad aus</td> <td> </td> </tr> <tr> <td>9AR, 9BR, 9CR</td> <td>62. </td> <td>BEH </td> <td> </td> <td>sd </td> <td>fasda aus</td> <td> </td> </tr> <tr> <td> </td> <td>6. </td> <td>MLR </td> <td> </td> <td>FdR </td> <td>fsdfaus</td> <td> </td> </tr> If he types in 5CG: <tr> <td>5CG </td> <td>aass </td> <td>sxs </td> <td>sx </td> <td>EK </td> <td> </td> <td>72 </td> </tr> <td> </td> <td>samplxs </td> <td>xs </td> <td> </td> <td>xss </td> <td>fkxsx aus</td> <td>s </td> </tr> Or if 6CG just: <tr> <td>6CG </td> <td>3. </td> <td>sfd </td> <td> </td> <td>scs </td> <td>das aus</td> <td>a </td> </tr>

  • Date formats in ActiveRecord / Rails 3

    - by cbmeeks
    In my model, I have a departure_date and a return_date. I am using a text_field instead of the date_select so that I can use the JQuery datepicker. My app is based in the US for now but I do hope to get international members. So basically this is what is happening. The user (US) types in a date such as 04/01/2010 (April 1st). Of course, MySQL stores it as a datetime such as 2010-04-01... Anyway, when the user goes to edit the date later on, it shows "01/04/2010" because I am using a strftime("%m/%d/%Y) which doesn't make sense....so it thinks it is January 4th instead of the original April 1st. It's like the only way to accurately store the data is for the user to type in: 2010-04-01 I hope all of this makes sense. What I am really after is a way for the user to type in (or use the datepicker) a date in their native format. So someone in Europe could type in 01/04/2010 for April 1st but someone in the US would type in 04/01/2010. Is there an easy, elegant solution to this? Thanks for any suggestions.

  • Java reflection

    - by heldopslippers
    Hi people. I have a question about reflection I am trying to have some kind of eval() method. So i can call for example: eval("test('woohoo')"); Now I understand the there is no eval method in java but there is reflection. I made the following code: String s = "test"; Class cl = Class.forName("Main"); Method method = cl.getMethod(s, String.class); method.invoke(null, "woohoo"); This works perfectly (of course there is a try, catch block around this code). It runs the test method. However I want to call multiple methods who all have different parameters. I don't know what parameters these are (so not only String.class). But how is this possible? how can I get the parameter types of a method ? I know of the following method: Class[] parameterTypes = method.getParameterTypes(); But that will return the parameterTypes of the method I just selected! with the following statement: Method method = cl.getMethod(s, String.class); Any help would be appreciated !

  • Magento - Show Custom Attributes in Grouped Product table.

    - by greencoconut
    I need to find a way to show the value of a custom attribute in place of the "Product Name" shown in the image below. I'm working with /app/design/frontend/default/defaultx/template/catalog/product/view/type/grouped.php The code below doesn't work(the custom attribute is yearmade): <?php if (count($_associatedProducts)): ?> <?php foreach ($_associatedProducts as $_item): ?> <tr> <td><?php echo $this->htmlEscape($_item->getYearmade()) ?></td> Any help would be appreciated. EDIT: So the answer turned out to be quite simple. You see what I failed to mention above was that there was indeed output... but that it was just a number (eg: 52). Turns out this was the ID for that custom attribute value (It was a Dropdown type of custom attribute). So in summary This works for custom attributes of type text: echo $this->htmlEscape($_item->getYearmade()) But for all other types of custom attribute (I think), the following should be used: echo $this->htmlEscape($_item->getAttributeText('yearmade')) I would not have discovered this without the most excellent answer provided by Alan Storm, below. Thank you sir.

  • Struggling with a data modeling problem

    - by rpat
    I am struggling with a data model (I use MySQL for the database). I am uneasy about what I have come up with. If someone could suggest a better approach, or point me to some reference matter I would appreciate it. The data would have organizations of many types. I am trying to do a 3 level classification (Class, Category, Type). Say if I have 'Italian Restaurant', it will have the following classification Food Services Restaurants Italian However, an organization may belong to multiple groups. A restaurant may also serve Chinese and Italian. So it will fit into 2 classifications Food Services Restaurants Italian Food Services Restaurants Chinese The classification reference tables would be like the following: ORG_CLASS (RowId, ClassCode, ClassName) 1, FOOD, Food Services ORG_CATEGORY(RowId, ClassCode, CategoryCode, CategoryName) 1, FOOD, REST, Restaurants ORG_TYPE (RowId, ClassCode, CategoryCode, TypeCode, TypeName) 100, FOOD, REST, ITAL, Italian 101, FOOD, REST, CHIN, Chinese 102, FOOD, REST, SPAN, Spanish 103, FOOD, REST, MEXI, Mexican 104, FOOD, REST, FREN, French 105, FOOD, REST, MIDL, Middle Eastern The actual data tables would be like the following: I will allow an organization a max of 3 classifications. I will have 3 GroupIds each pointing to a row in ORG_TYPE. So I have my ORGANIZATION_TABLE ORGANIZATION_TABLE (OrgGroupId1, OrgGroupId2, OrgGroupId3, OrgName, OrgAddres) 100,103,NULL,MyRestaurant1, MyAddr1 100,102,NULL,MyRestaurant2, MyAddr2 100,104,105, MyRestaurant3, MyAddr3 During data add, a dialog could let the user choose the clssa, category, type and the corresponding GroupId could be populated with the rowid from the ORG_TYPE table. During Search, If all three classification are chosen, It will be more specific. For example, if Food Services Restaurants Italian is the criteria, the where clause would be 'where OrgGroupId1 = 100' If only 2 levels are chosen Food Services Restaurants I have to do 'where OrgGroupId1 in (100,101,102,103,104,105, .....)' - There could be a hundred in that list I will disallow class level search. That is I will force selection of a class and category The Ids would be integers. I am trying to see performance issues and other issues. Overall, would this work? or I need to throw this out and start from scratch.

  • C# naming convention for enum and matching property

    - by Serge - appTranslator
    Hi All, I often find myself implementing a class maintaining some kind of own status property as an enum: I have a Status enum and ONE Status property of Status type. How should I solve this name conflict? public class Car { public enum Status { Off, Starting, Moving }; Status status = Status.Off; public Status Status // <===== Won't compile ===== { get { return status; } set { status = value; DoSomething(); } } } If the Status enum were common to different types, I'd put it outside the class and the problem would be solved. But Status applies to Car only hence it doesn't make sense to declare the enum outside the class. What naming convention do you use in this case? NB: This question was partially debated in comments of an answer of this question. Since it wasn't the main question, it didn't get much visibility. EDIT: Filip Ekberg suggests an IMO excellent workaround for the specific case of 'Status'. Yet I'd be interesting to read about solutions where the name of the enum/property is different, as in Michael Prewecki's answer. EDIT2 (May 2010): My favorite solution is to pluralize the enum type name, as suggested by Chris S. According to MS guidelines, this should be used for flag enums only. But I've come to like it more and more. I now use it for regular enums as well.

    - by galford13x
    I have a database that contains a history of product sales. For example the following table CREATE TABLE SalesHistoryTable ( OrderID, // Order Number Unique to all orders ProductID, // Product ID can be used as a Key to look up product info in another table Price, // Price of the product per unit at the time of the order Quantity, // quantity of the product for the order Total, // total cost of the order for the product. (Price * Quantity) Date, // Date of the order StoreID, // The store that created the Order PRIMARY KEY(OrderID)); The table will eventually have millions of transactions. From this, profiles can be created for products in different geographical regions (based on the StoreID). Creating these profiles can be very time consuming as a database query. For example. SELECT ProductID, StoreID, SUM(Total) AS Total, SUM(Quantity) QTY, SUM(Total)/SUM(Quantity) AS AvgPrice FROM SalesHistoryTable GROUP BY ProductID, StoreID; The above query could be used to get the Information based on products for any particular store. You could then determine which store has sold the most, has made the most money, and on average sells for the most/least. This would be very costly to use as a normal query run anytime. What are some design descisions in order to allow these types of queries to run faster assuming storage size isn’t an issue. For example, I could create another Table with duplicate information. Store ID (Key), Product ID, TotalCost, QTY, AvgPrice And provide a trigger so that when a new order is received, the entry for that store is updated in a new table. The cost for the update is almost nothing. What should be considered when given the above scenario?

  • @font-face fonts only work on their own domain

    - by Ben
    I am trying to create a type of font repository for use on my websites, so that I can call to any font in the repository in my css without any other set-up. To do this I created a subdomain on which I placed folders for each font in the repository that contained the various file types for each font. I also placed a css file called font-face.css on the root of the subdomain and filled it with @font-face declarations for each of the fonts, the fonts a linked with an absolute link so that they can be used from anywhere. My issue is that it seems that I can only use the fonts on that subdomain where they are located, on my other sites the font does not show. Using firebug I determined that the font-face.css file was successfully being linked to and loaded. So why does the font not correctly load? Is there protection on the font files or something? I am using all fonts that I should be allowed to do this with, so I don't see why this is occurring. Maybe it is an apache issue, but I can download the font just fine when I link to it. Oh, and just to clarify, I am not violating any copyrights by setting this up, all the fonts I am using are licensed to allow this sort of thing. I would however like to set up a way that only I can have access to this repository of fonts but that's another project.

  • TFS and Forms Authentication

    - by George
    I don't know squat about TFS, other than as a user who has performed simple check in/outs. I just installed it locally and would like to do joint development with a friend. I was having trouble making my TFS web site on port 8080 visible (the whole scoop is here if your interested) and I wonder if it could be related to the fact that TFS is probably using Windows Authentication to identify the user. Can TFS be set up to use forms authentication? We probably need to set up a VPN, though that's a learning curve too. To use TFS, do our machines have to belong to a domain? We're not admin types, though he is better than me, though I would be interested in any feedback or advice on which path is likely to pan out the best. I already got AxoSoft OneTime working in this type of an environment and it suits us well, but I am tempted at all the bells & whistles with TFS and the ability to tie tracked bug items to code changes. As far as finding a good way to share code, do sites like SourceForge allow one to keep code secure among members only?

  • Facebook IOS SDK: Error in Publish Story Dialog

    - by lividsquirrel
    I've successfully set up the "DemoApp" project from the Facebook IOS SDK to use my "OKC ThunderCast" Facebook application. I have also configured another "Tester" application from scratch to successfully use the Facebook SDK and publish stories to my news feed. However, in my production application, I always get this result when calling the "dialog" method. The full description of the error message is "Error on line 52 at column 17: Opening and ending tag mismatch: div line 0 and body" Here's a detailed walkthrough of all of my code to make sure nothing is missed. 1) A UIViewController calls the "authorize" method NSArray *fbPerms = [NSArray arrayWithObjects:@"read_stream", @"offline_access", nil]; [[FacebookSingleton sharedInstance].facebook authorize:fbPerms delegate:self]; Note: The FacebookSingleton is a class I wrote that always returns a single instance of the "Facebook" class. I am using it successfully in other applications. 2) Safari is opened and the user is successfully authenticated and authorized 3) The application is called back and the "handleOpenUrl" method is called, which calls the "fbDidLogin" method of the UIViewController - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { Facebook *fb = [FacebookSingleton sharedInstance].facebook; return [fb handleOpenURL:url]; } 4) The same UIViewController handles the "fbDidLogin" event, and calls the "dialog" method - (void)fbDidLogin { [[FacebookSingleton sharedInstance].facebook dialog:@"feed" andDelegate:self]; } I also have the necessary "URL Schemes" and "URL Types" entries in the .plist file. To my eyes, I am using exactly the same code in the "DemoApp", "Tester", and production applications. But while the DemoApp and Tester work, I always see this HTML error in the feed dialog in my production application. Has anyone seen a similar issue? Could it be related to the Facebook "Bundle ID" setting in the Facebook application settings? Is there some build or .plist setting that is different? I have invested a great deal of time into troubleshooting with no success in several weeks. Thanks in advance...

  • What is the rationale to non allow overloading of C++ conversions operator with non-member functio

    - by Vicente Botet Escriba
    C++0x has added explicit conversion operators, but they must always be defined as members of the Source class. The same applies to the assignment operator, it must be defined on the Target class. When the Source and Target classes of the needed conversion are independent of each other, neither the Source can define a conversion operator, neither the Target can define a constructor from a Source. Usually we get it by defining a specific function such as Target ConvertToTarget(Source& v); If C++0x allowed to overload conversion operator by non member functions we could for example define the conversion implicitly or explicitly between unrelated types. template < typename To, typename From operator To(const From& val); For example we could specialize the conversion from chrono::time_point to posix_time::ptime as follows template < class Clock, class Duration operator boost::posix_time::ptime( const boost::chrono::time_point& from) { using namespace boost; typedef chrono::time_point time_point_t; typedef chrono::nanoseconds duration_t; typedef duration_t::rep rep_t; rep_t d = chrono::duration_cast( from.time_since_epoch()).count(); rep_t sec = d/1000000000; rep_t nsec = d%1000000000; return posix_time::from_time_t(0)+ posix_time::seconds(static_cast(sec))+ posix_time::nanoseconds(nsec); } And use the conversion as any other conversion. So the question is: What is the rationale to non allow overloading of C++ conversions operator with non-member functions?

  • What data structure to use / data persistence

    - by Dave
    I have an app where I need one table of information with the following fields: field 1 - int or char field 2 - string (max 10 char) field 3 - string (max 20 char) field 4 - float I need the program to filter on field 1 based upon a segmented control and select a field 2 from a picker. From this data I need to look up field 4 to use in a calculation. Total records will be about 200. I never see it go above 400 - 500. I am going to use a singleton which I am able to do, I just need help with the structure for this with data persistence. What type of data structure should I use for this and should I use NSNumber, NSString, etc. or old data types like float, Char, etc. I thought about a struct put into an array but there is probably a better way. This is new to me so any help or reference to examples would be great. I also thought about a plist or dictionary but it looks like it is just a lookup and a field which obviously won't work. Core data looked like overkill to me. Also, with any recommendation how should I get initial data into it? I want the user to be able to edit and add to the database. Sorry for the old terms, you can see what generation I am from... Thanks in advance!!!!
