  • .submit() changes post data

    - by ajbeaven
    I'm posting a form with javascript and it seems to be changing a value that I've entered in. Html: <% using (Html.BeginForm("ChangeTime", "Cart", new { cartItemId = cartItem.CartItemID }, FormMethod.Post, null)) { %> <%= Html.TextBox("startTime")%> <input type="submit" value="Update" /> <% } %> JQuery: <script type="text/javascript"> $('#startTime').change(function() { $(this).parent('form').submit(); }); </script> When I put a time in the textbox (05/05/2010 06:08 am), the form is submitted, however the string as it comes through, is 05/05/2010 - with the time part removed. I see this in fiddler. If get rid of the javascript and click the button above, it goes through how it should. Why is JQuery changing my text?

  • Rendering maps from raw SVG data in Java

    - by Lunikon
    In an application of mine I have to display locations and great circle paths in a map which is rendered to PNG and then displayed on the web. For this I simply use a world map (NASA's Blue Marbel in fact) scaled to various "zoom levels" as base image and only display the a part of it matching the final image size and fitting all items to be displayed. Straight forward so far. Now I came across Wikipedia's awesome blank SVG maps which contain all the country codes for easy reference and I was wondering whether it was possible to use those to have more customized colors and to highliht countries etc. So I did a bit of googling and was looking for Java libraries which would enable me to load the blank SVG map to memory allows for easy reference/selection of certain paths do manipulations of coloring, stroke widths etc render to a buffered image as the background for the great-circle paths/nodes What I came across quite often was Batik, but it looks like a really heavy framework and I'm not quite sure whether it is what I'm looking for. I have recently played around with Raphaël a bit and I like the way it handles working with vector graphics in code. If the Java framework for my purpose would feature a similar interface, that would be a nice-to-have. Any recommendations what toolset would be approriate for my purposes?

  • Python method to remove iterability

    - by Debilski
    Suppose I have a function which can either take an iterable/iterator or a non-iterable as an argument. Iterability is checked with try: iter(arg). Depending whether the input is an iterable or not, the outcome of the method will be different. Not when I want to pass a non-iterable as iterable input, it is easy to do: I’ll just wrap it with a tuple. What do I do when I want to pass an iterable (a string for example) but want the function to take it as if it’s non-iterable? E.g. make that iter(str) fails.

  • Check for live Data Source Name Before proceeding

    - by n_kips
    Would it be ok to get a CF app to check for a valid database before proceeding to process that request? This is because there may be instances where the database server may be down or being upgraded, hence an error comes when a db dependant request is made. If there is no connection to the db server, the user can be safely redirected to a safe page. Or can cfcatch work? How can this check be done? Thank you.

  • Any big difference between using contains or loop through a list?

    - by Nazgulled
    Hi, Performance wise, is there really a big difference between using: ArrayList.contains(o) vs foreach|iterator LinkedList.contains(o) vs foreach|iterator HashMap.(containsKey|containsValue) vs foreach|iterator TreeMap.(containsKey|containsValue) vs foreach|iterator Of course, for the foreach|iterator loops, I'll have to explicitly compare the methods and return true or false accordingly. The object I'm comparing is an object where equals() and hashcode() are both properly overridden.

  • CoreData is saving model without the save: method being called

    - by chris
    I have a list of items with a plus button in the navigation bar that opens up a modal window containing a table of the models attributes, that displays a form when the table items are clicked (pretty standard form style). For some reason if I click the plus button to open the form to create a new model, then immediately click the done button, the person model is saved. The action linked to the done button does nothing but call on a delegate method notifying the personListViewController to close the window. The apple docs do state that the model is not saved after calling the insertNewObjectForEntityName: ... Simply creating a managed object does not cause it to be saved to a persistent store. The managed object context acts as a scratchpad. I am at a lost to why this is happening, but every time I click the done button I have a new blank item in the original tableView. I am using SDK v3.1.3 // PersonListViewController - open modal window - (void)addPerson { // Load the new form PersonNewViewController *newController = [[PersonNewViewController alloc] init]; newController.modalFormDelegate = self; [self presentModalViewController:newController animated:YES]; [newController release]; } // PersonFormViewController - (void)viewDidLoad { [super viewDidLoad]; if ( person == nil ) { MyAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; self.person = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:appDelegate.managedObjectContext]; } ... UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; } - (IBAction) done { [self.modalFormDelegate didCancel]; } // delegate method in the original listViewController - (void) didCancel { [self dismissModalViewControllerAnimated:YES]; }

  • How to extract the lat/lng of pins in google maps?

    - by BCS
    I want to extract the latitude and longitude of a set of about 50-100 pins in a Google maps web page. I don't control the page and I don't need to do it more than once so I'm looking for something quick and dirty. I've got FireFox with FireBug as well as Chrome and all I need is something that's easier than re typing all the numbers.

  • rails large amount of data in single insert activerecord gave out

    - by Nik
    So I have I think around 36,000 just to be safe, a number I wouldn't think was too large for a modern sql database like mysql. Each record has just two attributes. So I do: so I collected them into one single insert statement sql = "INSERT INTO tasks (attrib_a, attrib_b) VALUES (c1,d1),(c2,d2),(c3,d3)...(c36000,d36000);" ActiveRecord::Base.connection.execute sql from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/abstract_adapter.rb:219:in `log' from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/mysql_adapter.rb:323:in `execute_without_analyzer from c:/r/projects/vendor/plugins/rails-footnotes/lib/rails-footnotes/notes/queries_note.rb:130:in `execute' from C:/Ruby/lib/ruby/1.8/benchmark.rb:308:in `realtime' from c:/r/projects/vendor/plugins/rails-footnotes/lib/rails-footnotes/notes/queries_note.rb:130:in `execute' from (irb):53 from C:/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/vendor/tzinfo-0.3.12/tzinfo/time_or_datetime.rb:242 I don't know if the above info is enough, please do ask for anything that I didn't provide here. So any idea what this is about? THANK YOU!!!!

  • Iterative printing over two data types in Python

    - by old Ixfoxleigh
    I often browse freely-available art on the web. Actually, I can't think of a better use for the internet than to turn it into a gigantic art gallery. When I encounter a set of pieces I quite like, I download them all to my hard drive. wget makes that easy, especially in combination with Python's print function, and I use this all the time to make a list of URLs that I then wget. Say I need to download a list of jpegs that run from art0 to art100 in the directory 'art,' I just tell python for i in range(0,101): print "http://somegallery/somedirectory/art", i So, this is probably a fairly simple operation in Python, and after a find-and-replace to remove whitespace, it's just a matter of using wget -i, but in days before I knew any Python I'd slavishly right-click and save. Now I've got a bunch of files from Fredericks & Freiser gallery in New York that all go a(1-14), b(1-14), c(1-14), etc., up to the letter g. I could do that in 7 goes, and it would take me less time than it took to write this SO question. That said, I want to deepen my knowledge of Python. So, given the letters a-g, how do I print a mapping of each letter to the integers 1-14?

  • Building a NSPredicate for a filter

    - by John
    Hi, Just wondering what the best way to build a NSPredicate is if some filters are optional? This is basically for a filter, so if some options aren't selected I don't to filter by them eg. If I have option1 and option2 set for the filter. NSPredicate* predicate = [NSPredicate predicateWithFormat:@"option1 = %@ AND option2 = %@] .... otherwise if just option1 NSPredicate* predicate = [NSPredicate predicateWithFormat:@"option1 = %@] .... The key being there are 10 different options to filter, so I don't want to have to code for the 10x10 possible combinations. Thanks

  • NSData in CoreData is not saving properly

    - by abisson
    I am currently trying to store images I download from the web into an NSManagedObject class so that I don't have to redownload it every single time the application is opened. I currently have these two classes. Plant.h @property (nonatomic, retain) NSString * name; @property (nonatomic, retain) PlantPicture *picture; PlantPicture.h @property (nonatomic, retain) NSString * bucketName; @property (nonatomic, retain) NSString * creationDate; @property (nonatomic, retain) NSData * pictureData; @property (nonatomic, retain) NSString * slug; @property (nonatomic, retain) NSString * urlWithBucket; Now I do the following: - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath { PlantCollectionCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:CellIdentifier forIndexPath:indexPath]; Plant *plant = [self.fetchedResultsController objectAtIndexPath:indexPath]; cell.plantLabel.text = plant.name; if(plant.picture.pictureData == nil) { NSLog(@"Downloading"); NSMutableString *pictureUrl = [[NSMutableString alloc]initWithString:amazonS3BaseURL]; [pictureUrl appendString:plant.picture.urlWithBucket]; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:pictureUrl]]; AFImageRequestOperation *imageOperation = [AFImageRequestOperation imageRequestOperationWithRequest:request success:^(UIImage *image) { cell.plantImageView.image = image; plant.picture.pictureData = [[NSData alloc]initWithData:UIImageJPEGRepresentation(image, 1.0)]; NSError *error = nil; if (![_managedObjectContext save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); } }]; [imageOperation start]; } else { NSLog(@"Already"); cell.plantImageView.image = [UIImage imageWithData:plant.picture.pictureData]; } NSLog(@"%@", plant.name); return cell; } The plant information is present, as well as the picture object. However, the NSData itself is NEVER saved throughout the application opening and closing. I always have to REDOWNLOAD the image! Any ideas!? [Very new to CoreData... sorry if it is easy!] thanks!

  • Grabbing Data From Controls In Code Behind

    - by MKell43
    Hopefully this is a pretty simple question for someone to answer. I have a drop down list control that I need to pull the value from in the code behind of the page, modify it and redisplay it. The modifying and redisplaying I've got no problem with, it's grabing the value from the drop down control. Examples in C# would be appreciated as this web app I've been handed is already coded that way. I'm pretty new to .Net so be gentle and I already did some searching via Google and a little bit on the site here, but couldn't find anything that stood out as being the direction to go in to do this.

  • converting date data type into varchar

    - by Sheetal Inani
    I have some dates fields in table. These columns contain dates in the following format: mmddyy For example: 31/12/2010 00:00:00:0000 I need to import these values into a table which is set to varchar and numeric and formats dates like this: monthName varchar Year numeric(4,0) currently I'm using INSERT INTO [School].[dbo].[TeacherAttendenceDet] ([TeacherCode], [MonthName], [Year]) (SELECT MAX(employeecode), Datename(MONTH, dateofjoining) AS MONTH, Datepart(YEAR, dateofjoining) AS DATE FROM employeedet GROUP BY dateofjoining) but datename() gives result in date format.. I have to save it in varchar format How can I do this? this is employeemast table: EmployeeCode numeric(5, 0) PayScaleCode numeric(7, 0) DesignationCode varchar(50) CityCode numeric(5, 0) EmployeeName varchar(50) FatherName varchar(50) BirthDate varchar(50) DateOfJoining varchar(50) Address varchar(150) this is TeacherAttendenceDet table TeacherCode numeric(5, 0) Unchecked Year numeric(4, 0) Unchecked MonthName varchar(12) Unchecked i have to insert in teacherattendencedet table the monthname and year from employeemast

  • Import part with specific meta data using MEF Preview 5

    - by Riri
    I have a export defined as as follows in MEF preview 5 [ExportMetadata("Application", "CheckFolderApplication")] [Export(typeof(ExtendedArtifactBase))] public class CheckFolderArtifact2 : ExtendedArtifactBase { ... Then I only want those imports with the "Application" "CheckFolderApplication" metadata. To currenly do that I read all the imports and then filter the result. [Import(typeof(ExtendedApplicationBase))] private ExportCollection<IApplication> _applications { get; set; } public IApplication GetApplication(string applicationName) { return _applications.Single(a => a.GetExportedObject().Name == applicationName).GetExportedObject(); } This feels really inefficient. What if I have thousands of plug-ins - do I have to read them all via MEF to just get one with the right metadata? If so how do you cache the result?

  • Customising log4j logging for sensitive data

    - by Xetius
    I have a class which contains sensitive information (Credit card info, phone numbers etc). I want to be able to pass this class to log4j, but have it obscure certain information. If I have a class UserInformation which has getPhoneNumber, getCreditCardNumber methods, how would I customise log4j or this class so that it will obscure the numbers correctly. I want the credit card number to be output as xxxx-xxxx-xxxx-1234 and the phone number to be output as xxxx-xxx-xxx given that these would be 1234-1234-1234-1234 and 1234-567-890 Thanks

  • flex data provider not working if XML has single node value or less

    - by Rees
    hello, i get this error when i retrieve an XML that only has 1 node (no repeating nodes) and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error. My test show that XMLListCollection does NOT work either. TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection. this error occurs as the line of code: myList= e.result.list.name; Why can't ArrayCollection work with a single node? I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider? Thanks in advance! code: [Bindable] private var myList:ArrayCollection= new ArrayCollection(); private function getList(e:Event):void{ var getStudyLoungesService:HTTPService = new HTTPService(); getStuffService.url = "website.com/asdf.php"; getStuffService.addEventListener(ResultEvent.RESULT, onGetList); getStuffService.send(); } private function onGetList(e:ResultEvent):void{ myList= e.result.list.name; }

  • Tree-like queues

    - by Rehno Lindeque
    I'm implementing a interpreter-like project for which I need a strange little scheduling queue. Since I'd like to try and avoid wheel-reinvention I was hoping someone could give me references to a similar structure or existing work. I know I can simply instantiate multiple queues as I go along, I'm just looking for some perspective by other people who might have better ideas than me ;) I envision that it might work something like this: The structure is a tree with a single root. You get a kind of "insert_iterator" to the root and then push elements onto it (e.g. a and b in the example below). However, at any point you can also split the iterator into multiple iterators, effectively creating branches. The branches cannot merge into a single queue again, but you can start popping elements from the front of the queue (again, using a kind of "visitor_iterator") until empty branches can be discarded (at your discretion). x -> y -> z a -> b -> { g -> h -> i -> j } f -> b Any ideas? Seems like a relatively simple structure to implement myself using a pool of circular buffers but I'm following the "think first, code later" strategy :) Thanks
