  • Constructor overriding

    - by demas
    I have a library with a class: class One def initialize puts "one initialize" end end I can not change the declaration and difinition of this class. I need create new class with my own constructor. Like this: class Two < One def initialize(some) puts some super end end one = One.new one = Two.new("thing") But when I launch code I got error: [[email protected]][~/temp]% ruby test.rb one initialize thing test.rb:10:in `initialize': wrong number of arguments (1 for 0) (ArgumentError) from test.rb:15:in `new' from test.rb:15:in `<main>'

  • Change a UIButton View's background upon press

    - by Michael
    This should be easy but its got me stumped. I've got a button on each row of a table cell. The button is to delete the file associated with that row. I have an image that indicates if the file is present on the iPhone or not present. When the user presses the button, the target action method (showDeleteSheet) then calls a UIActionSheet with a variable to give it the indexPath of the row pressed. Then the user presses delete on the action sheet and the action sheet's clickedButtonAtIndex method deletes the file. Now, I need to update the button's background image property to change the image in the appropriate table cell to the not downloaded image. This can be done in either the button's target action method or the action sheet's clickedButtonAtIndex method. Here is some code: In the table's cellForRowAtIndexPath method I create the button: UIButton *deleteButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; [deleteButton addTarget:self action:@selector(showDeleteSheet:) forControlEvents:UIControlEventTouchDown]; deleteButton.frame = CGRectMake(246, 26, 30, 30); if (![AppData isDownloaded:[dets objectForKey:@"fileName"]]) { [deleteButton setBackgroundImage:notdownloadedImage forState:UIControlStateNormal]; } else { [deleteButton setBackgroundImage:notdownloadedImage forState:UIControlStateNormal]; } In the button's target method: -(void)showDeleteSheet:(id)sender { //get the cell row that the button is in NSIndexPath *indexPath = [table indexPathForCell:(UITableViewCell *)[[sender superview] superview]]; NSInteger currentSection = indexPath.section; NSInteger currentIndexRow = indexPath.row; NSLog(@"section = %i row = %i", currentSection, currentIndexRow); UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeCustom]; [table reloadData]; //if deleteButton is declared in .h then the other instances of deleteButton show 'local declaration hides instance variable' [deleteButton setBackgroundImage:[UIImage imageNamed:@"not-downloaded.png"] forState:UIControlStateNormal]; UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Delete this file?" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Delete" otherButtonTitles:nil]; actionSheet.tag = currentIndexRow; actionSheet.actionSheetStyle = UIActionSheetStyleDefault; [actionSheet showInView:self.view]; [actionSheet release]; } Perhaps the issue is that the call to [deleteButton setBackgroundImage...]; doesn't know which cell's button should be updated. If so I don't know how to tell it which. Because I test if the file is downloaded when the button is made and the background image is set, when I scroll down so the cell in question is de-queued then scroll back up it show's the correct image. I've tried to force the table to reload but [table reloadData]; is doing nothing. I've tried reloadRowsAtIndexPaths and still no good. Any one care to educate me on how this is done?

  • SQL Split function.

    - by Wardy
    Hi guys, I'm looking for a way to do this ... SELECT FirstName, LastName, Split(AddressBlock, ' ', 1), Split(AddressBlock, ' ', 2), PostCode FROM Contacts The arguments I want to pass are ... The address The separator (current situation requires 2 spaces but this might be a comma or a space followed by a comma) or something else (it varies). The address part I want to return (i don't always need all parts of the split result). I seem to be able to find a few examples of splitting functions about the internet but they return a table containing the entire set of split parts. My SQL skills aren't that great so I need the answer to be ultra simple. I'm always working with nvarchar data and the function needs to be reusable.

  • using the data-custom="" to bind to events

    - by Dean Peterson
    I'm pretty sure I'm gonna get slammed on this. I love using the data-whatever attribute to bind events to. It feels very clean to me and helps reserve my class attribute for just styling. I know this selector is among the slowest, so I don't use it when there are a lot of elements. Would love to hear compelling arguments against this. $("body").delegate("[data-action]", "click", function(){ var action = $(this).attr("data-action"); //route action to appropriate function });

  • Dealing with PHP server and MySQL server in different time zones

    - by Kyle Noland
    For those of us who use standard shared hosting packages, such as GoDaddy or Network Solutions, how do you handle datetime conversions when your hosting server (PHP) and MySQL server are in different time zones? Also, does anybody have some best practice advice for determining what time zone a visitor to your site is in and manipulating a datetime variable appropriately?

  • Cocoa NSOutputStream send to a connection

    - by Chuck
    Hi, I am new to Cocoa, but managed to get a connection (to a FTP) up and running, and I've set up an eventhandler for the NSInputStream iStream to alert every response (which also works). What I manage to get is simply the hello message and a connection timeout 60 sec, closing control connection. After searching stackoverflow and finding a lot of NSOutputStream write problems (e.g. http://stackoverflow.com/questions/703729/how-to-use-nsoutputstreams-write-message) and a lot of confusion in my google hits, I figured I'd try to ask my own question: I've tried reading the developer.apple.com doc on OutputStream, but it seems almost impossible for me to send some data (in this case just a string) to the "connection" via the NSOutputStream oStream. - (IBAction) send_something: sender { const char *send_command_char = [@"USER foo" UTF8String]; send_command_buffer = [NSMutableData dataWithBytes:send_command_char length:strlen(send_command_char) + 1]; uint8_t *readBytes = (uint8_t *)[send_command_buffer mutableBytes]; NSInteger byteIndex = 0; readBytes += byteIndex; int data_len = [send_command_buffer length]; unsigned int len = ((data_len - byteIndex >= 1024) ? 1024 : (data_len-byteIndex)); uint8_t buf[len]; (void)memcpy(buf, readBytes, len); len = [oStream write:(const uint8_t *)buf maxLength:len]; byteIndex += len; } the above seems not to result in any useable events. typing it under NSStreamEventHasSpaceAvailable sometimes give a response if I spam the ftp by keep creating new connection instances and keep sending some command whenever oStream has free space. In other words, nothing "right" and so I'm still unclear how to properly send a command to the connection. Should I open - write - close every time i want to write to oStream (and thus to the ftp) and can I then expect a reply (hasBytesAvailable event on iStream)? For some reason I find it very difficult to find any clear tutorials on this matter. Seems like there are more than a few in the same position as me: unclear how to use oStream write? Any little bit that can help clear this up is greatly appreciated! If needed I can write the rest of the code. Chuck

    What is an easy way to remove the querystring from a Path in Javascript? I have seen a plugin for Jquery that uses window.location.search. I can not do that: The URL in my case is a variable that is set from AJAX. var testURL = '/Products/List?SortDirection=dsc&Sort=price&Page=3&Page2=3&SortOrder=dsc'

  • Why is RAISERROR misspelled? Or is it not?

    - by Jason
    Why isn't RAISERROR spelled RAISEERROR? Where is the second E? I could understand if it were some ancient keyword length constraint, but I wouldn't expect it to be a nine-character limit. Is RAIS or RROR a technical word such that "raise-error" is just a mis-reading? Are its (immediate) origins in a different language? I've searched Google but not finding much on the subject.

  • Error processing Spree sample images - file not recognized by identify command in paperclip geometry.rb:29

    - by purpletonic
    I'm getting an error when I run the Spree sample data. It occurs when Spree tries to load in the product data, specifically the product images. Here's the error I'm getting: * Execute db:load_file loading ruby <GEM DIR>/sample/lib/tasks/../../db/sample/spree/products.rb -- Processing image: ror_tote.jpeg rake aborted! /var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-21549-2rktq1 is not recognized by the 'identify' command. <GEM DIR>/paperclip-2.7.1/lib/paperclip/geometry.rb:31:in `from_file' <GEM DIR>/spree/core/app/models/spree/image.rb:35:in `find_dimensions' I've made sure ImageMagick is installed correctly, as previously I was having problems with it. Here's the output I'm getting when running the identify command directly. $ identify Version: ImageMagick 6.7.7-6 2012-10-06 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC Features: OpenCL ... other usage info omitted ... I also used pry with the pry-debugger and put a breakpoint in geometry.rb inside of Paperclip. Here's what that section of geometry.rb looks like: # Uses ImageMagick to determing the dimensions of a file, passed in as either a # File or path. # NOTE: (race cond) Do not reassign the 'file' variable inside this method as it is likely to be # a Tempfile object, which would be eligible for file deletion when no longer referenced. def self.from_file file file_path = file.respond_to?(:path) ? file.path : file raise(Errors::NotIdentifiedByImageMagickError.new("Cannot find the geometry of a file with a blank name")) if file_path.blank? geometry = begin silence_stream(STDERR) do binding.pry Paperclip.run("identify", "-format %wx%h :file", :file => "#{file_path}[0]") end rescue Cocaine::ExitStatusError "" rescue Cocaine::CommandNotFoundError => e raise Errors::CommandNotFoundError.new("Could not run the `identify` command. Please install ImageMagick.") end parse(geometry) || raise(Errors::NotIdentifiedByImageMagickError.new("#{file_path} is not recognized by the 'identify' command.")) end At the point of my binding.pry statement, the file_path variable is set to the following: file_path => "/var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-22732-1ctl1g1" I've also double checked that this exists, by opening my finder in this directory, and opened it with preview app; and also that the program can run identify by running %x{identify} in pry, and I receive the same version Version: ImageMagick 6.7.7-6 2012-10-06 Q16 as before. Removing the additional digits (is this a timestamp?) after the file extension and running the Paperclip.run command manually in Pry gives me a different error: Cocaine::ExitStatusError: Command 'identify -format %wx%h :file' returned 1. Expected 0 I've also tried manually updating the Paperclip gem in Spree to 3.0.2 and still get the same error. So, I'm not really sure what else to try. Is there still something incorrect with my ImageMagick setup?

  • Bind multiple request parameters to one object in Spring 3

    - by Max
    Hi, I can't figure out a way to bind several arguments and headers to one request parameter using annotations in Spring 3. For example, let's say I'm getting this request: Headers: Content-type: text/plain; POST Body: Name: Max Now I want it all to mysteriously bind to this object: class NameInfo { String name; } Using some code like this: String getName() { if ("text/plain".equals(headers.get("content-type"))) { return body.get("name"); } else if ("xml".equals(headers.get("content-type")) { return parseXml(body).get("name"); } else ... } So that in the end I would be able to use: @RequestMapping(method = RequestMethod.POST) void processName(@RequestAttribute NameInfo name) { ... } Is there a way to achieve something similar to what I need? Thanks in advance.

  • Flex - Issues with linkbar dataprovider

    - by BS_C3
    Hello Community! I'm having some issues displaying a linkbar. The data I need to display is in a XML file. However, I couldn't get the linkbar to display a xmllist (I did indeed read that you cannot set a xmlllist as a linkbar dataprovider... ). So, I'm transforming the xmllist in a array of objects. Here is some code. XML file: <data> <languages> <language id="en"> <label>ENGLISH</label> <source></source> </language> <language id="fr"> <label>FRANCAIS</label> <source></source> </language> <language id="es"> <label>ESPAÑOL</label> <source></source> </language> <language id="jp"> <label>JAPANESE</label> <source></source> </language> </languages> </data> AS Code that transforms the xmllist in an array of objects: private function init():void { var list:XMLList = generalData.languages.language; var arr:ArrayCollection = new ArrayCollection; var obj:Object; for(var i:int = 0; i<list.length(); i++) { obj = new Object; obj.id = list[i].@id; obj.label = list[i].label; obj.source = list[i].source; arr.addItemAt(obj, arr.length); } GlobalData.instance.languages = arr.toArray(); } Linkbar code: <mx:HBox horizontalAlign="right" width="100%"> <mx:LinkBar id="language" dataProvider="{GlobalData.instance.languages}" separatorWidth="3" labelField="{label}"/> </mx:HBox> The separator is not displaying, and neither do the label. But the array is populated (I tested it). Thanks for any help you can provide =) Regards, BS_C3

  • Destructuring assignment in generator expressions and array comprehensions

    - by Eli Grey
    Why does for ([] in object); work fine but [void 0 for ([] in object)] or (void 0 for ([] in object)) throw a syntax error for invalid left-hand assignment? For example, I would expect the following code to work, but it doesn't (the assertion isn't even done due to the syntax error): let ( i = 0, arr = [1, 2, 3, 4], gen = (i for (i in arr) if (arr.hasOwnProperty(i)) ) { for ([] in gen) i++; console.assertEquals([void 0 for ([] in gen)].length, i); }
