  • Python: override __init__ args in __new__

    - by EoghanM
    I have a __new__ method as follows: class MyClass(object): def __new__(cls, *args): new_args = [] args.sort() prev = args.pop(0) while args: next = args.pop(0) if prev.compare(next): prev = prev.combine(next) else: new_args.append(prev) prev = next if some_check(prev): return SomeOtherClass() new_args.append(prev) return super(MyClass, cls).__new__(cls, new_args) def __init__(self, *args): ... However, this fails with a deprecation warning: DeprecationWarning: object.__new__() takes no parameters SomeOtherClass can optionally get created as the args are processed, that's why they are being processed in __new__ and not in __init__ What is the best way to pass new_args to __init__? Otherwise, I'll have to duplicate the processing of args in __init__ (without some_check)

  • Have a reloadData for a UITableView animate when changing

    - by Chris Butler
    Hi everyone. I have a UITableView that has two modes. When we switch between the modes I have a different number of sections and cells per section. Ideally, it would do some cool animation when the table grows or shrinks. Here is the code I tried, but it doesn't do anything: CGContextRef context = UIGraphicsGetCurrentContext(); [UIView beginAnimations:nil context:context]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration:0.5]; [self.tableView reloadData]; [UIView commitAnimations]; Any thoughts on how I could do this? Thanks in advance.

  • Modify installed SharePoint feature

    - by Laura L
    I have written a sequential workflow in SharePoint on our development environment. After testing, we decided to deploy this workflow as a feature on the staging environment. We did the following: copied the strongly named assembly to the GAC using gacutil copied feature.xml and workflow.xml to WebServerExtensions/12/templates/features/someFolder installed feature (stsadm command) activated feature (stsadm command) All worked exactly as planned and the workflow behaved correctly. The problem was, we decided to change something in the code (a message was not very self explanatory), so on the development machine we updated the message as requested and rebuilt the project. The problem is, we cannot seem to find a way to correctly get rid of the previous version of this workflow/feature. To deploy the upgrade, we: deactivated and uninstalled the feature (stsadm commands), removed also from GAC. increased the version of the assembly performed steps 1 to 4 from above. When using the workflow we are still getting the first message, we cannot find a way to get the new message to be displayed. What are we missing?

  • Active C++ project to contribute to

    - by Joseph Pond
    I am a self-taught c++/java programmer (I will be starting uni in August though!). I have worked on one project in which I was part of an active team. I really felt I learnt the most and gained a lot of experience while working with the team. Unfortunately it was a small closed source project which has recently taken a slumber. I'm looking for some active open source c++ projects which I could contribute to (preferably that are mainly developed on the linux platform). The other project I worked on was a video game, however, I would like to contribute to a project which has a functional purpose (other than to amuse). Any suggestions on possible projects?

  • How to load object after saving with encodeWithCoder?

    - by fuzzygoat
    EDIT_002: Further rewrite: if I save using the method below how would the method to load it back in look? (moons is an NSMutableArray of NSNumbers) // ------------------------------------------------------------------- ** // METHOD_002 // ------------------------------------------------------------------- ** -(void)saveMoons:(NSString *)savePath { NSMutableData *data = [[NSMutableData alloc] init]; NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [moons encodeWithCoder:archiver]; [archiver finishEncoding]; [data writeToFile:savePath atomically:YES]; [archiver release]; [data release]; } EDIT_003: Found it, my problem was that I was using ... [moons encodeWithCoder:archiver]; where I should have been using ... [archiver encodeObject:moons]; Hence the loader would look like: -(void)loadMoons_V3:(NSString *)loadPath { NSData *data = [[NSData alloc] initWithContentsOfFile:loadPath]; NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data]; [self setMoons:[unarchiver decodeObject]]; [unarchiver finishDecoding]; [unarchiver release]; [data release]; } gary

    - by Rob Paul
    I followed the steps on this tutorial video by at subsonic website. Everything seems to be self explanatory but when I copy the .tt files into my Visual Studio nothing happens. I have read other question relating to this problem on this website but they don't seem to fix this problem. I also went into the regedit to find out the generator key for .tt files and it is properly set. This is not a visual studio express or anything but a professional edition also I am trying to build a ASP.net web application and not a MVC application like the demo. Any help will be greatly appreciated. Thank You

  • Unable to view ChildWindows in Silverlight

    - by Doug Nelson
    So here is the deal. I have created a silverlight dll that contains two ChildWindow dialogs. These dialogs are self contained with a WCF service reference. I want to reuse these dialogs across multiple projects. I have added a reference to the dll in another project. I am able to new up the childWindow, however, I am not able to set the public properties on it and when I call the Show method, nothing is displayed. Not really sure where to start to figure out why this is not working.

  • How do I fix this NameError?

    - by Kyle Kaitan
    I want to use the value v inside of an instance method on the metaclass of a particular object: v = ParserMap[kind][:validation] # We want to use this value later. s = ParserMap[kind][:specs] const_set(name, lambda { p = Parser.new(&s) # This line starts a new scope... class << p define_method :validate do |opts| v.call(self, opts) # => NameError! The `class` keyword above # has started a new scope and we lost # old `v`. end end p }) Unfortunately, the class keyword starts a new scope, so I lose the old scope and I get a NameError. How do I fix this?

  • Remove another user's lock obtained with sp_getapplock on SQL Server

    - by joshperry
    We have a system that uses sp_getapplock to create an exclusive mutex any time someone opens an order in the GUI. This is used to prevent multiple people from making changes to an order simultaneously. Sometimes people will open an order and go home, leaving it open. This effectively blocks anyone from being able to make changes to the order. I then get emails, calls and end up doing a kill <spid> in enterprise manager. Obviously I've gotten sick of this and want to make a quick self-service webform. The main problem I've run into is that kill requires sysadmin privileges, which I do not want to give to the user that the our website runs as. I have tried sp_releaseapplock but this doesn't let you release another user's lock (even when calling it as a sysadmin). So, finally my question; does anyone know of an alternative method to release a lock that was obtained by another user using sp_getapplock?

  • iPhone: custom UITableViewCell with Interface Builder -> how to release cell objects?

    - by Stefan Klumpp
    The official documentation tells me I've to do these 3 things in order to manage the my memory for "nib objects" correctly. @property (nonatomic, retain) IBOutlet UIUserInterfaceElementClass *anOutlet; "You should then either synthesize the corresponding accessor methods, or implement them according to the declaration, and (in iPhone OS) release the corresponding variable in dealloc." - (void)viewDidUnload { self.anOutlet = nil; [super viewDidUnload]; } That makes sense for a normal view. However, how am I gonna do that for a UITableView with custom UITableViewCells loaded through a .nib-file? There the IBOutlets are in MyCustomCell.h (inherited from UITableViewCell), but that is not the place where I load the nib and apply it to the cell instances, because that happens in MyTableView.m So do I still release the IBOutlets in the dealloc of MyCustomCell.m or do I have to do something in MyTableView.m? Also MyCustomCell.m doesn't have a - (void)viewDidUnload {} where I can set my IBOutlets to nil, while my MyTableView.m does.

  • How can I detect when a file download has completed in ASP.NET?

    - by Alexis
    I have a popup window that displays "Please wait while your file is being downloaded". This popup also executes the code below to start the file download. How can I close the popup window once the file download has completed? I need some way to detect that the file download has completed so I can call self.close() to close this popup. System.Web.HttpContext.Current.Response.ClearContent(); System.Web.HttpContext.Current.Response.Clear(); System.Web.HttpContext.Current.Response.ClearHeaders(); System.Web.HttpContext.Current.Response.ContentType = fileObject.ContentType; System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", string.Concat("attachment; filename=", fileObject.FileName)); System.Web.HttpContext.Current.Response.WriteFile(fileObject.FilePath); Response.Flush(); Response.End();

  • Invoking play on a QTMovie causes screensaver to deactivate on Snow Leopard

    - by ressaw
    I'm trying to port a working Leopard screensaver to Snow Leopard but it's deactivating after about half a second. The screensaver seems to deactivate upon invoking play on a QTMovie. And it deactivates both upon -play on the QTMovie object itself, and -play:self on the QTMovieView. If I don't actually call -play on the object, the screensaver does not deactivate and sits still on the first frame of the movie. Setting up the same code in a regular Cocoa Application works fine, and the screensaver also works fine in preview mode in the System Preferences. Any help is greatly appreciated.

  • Serving files over HTTPS dynamically based on request.ssl? with Attachment_fu

    - by Marston A.
    I see there is a :user_ssl option in attachment_fu which checks the amazon_s3.yml file in order to serve files via https:// In the s3_backend.rb you have this method: def self.protocol @protocol ||= s3_config[:use_ssl] ? 'https://' : 'http://' end But this then makes it serve ALL s3 attachments with SSL. I'd like to make it dynamic depending if the current request was made with https:// i.e: if request.ssl? @protocol = "https://" else @protocol = "http://" end How can I make it work in this way? I've tried modifying the method and then get the NameError: undefined local variable or method `request' for Technoweenie::AttachmentFu::Backends::S3Backend:Module error

  • Programmatically adding a trusted cert in Java

    - by directedition
    I use SSL to communicate between two components written in Java. I can't use a CA, so I have to self-sign everything. Unfortunately, this means that when I try to handshake, I get a SunCertPathBuilderException. I can create my own X509TrustManager that just trusts everything, but that sort of defeats the purpose of having a signed cert. I would like, when first making the connection, to prompt the user with "SSL handshake with invalid cert. Add cert to store?" or something so they could have it added for them to their certificate store, like web browsers do at sites with invalid certs. I can find plenty of examples online of adding a cert to the store through the commandline, but I can't figure out how to do it programmatically. Is there a way to do this?

  • How Do You Profile & Optimize CUDA Kernels?

    - by John Dibling
    I am somewhat familiar with the CUDA visual profiler and the occupancy spreadsheet, although I am probably not leveraging them as well as I could. Profiling & optimizing CUDA code is not like profiling & optimizing code that runs on a CPU. So I am hoping to learn from your experiences about how to get the most out of my code. There was a post recently looking for the fastest possible code to identify self numbers, and I provided a CUDA implementation. I'm not satisfied that this code is as fast as it can be, but I'm at a loss as to figure out both what the right questions are and what tool I can get the answers from. How do you identify ways to make your CUDA kernels perform faster?

  • How to transfer url parameters to repoze custom predicate checkers

    - by user281521
    I would like to create a repoze custom predicate checker that is capable to access url parameters and validate something. But I would like to use allow_only to set this permission checker in all the controller's scope. Something like: class MyController(BaseController): allow_only = All(not_anonymous(msg=l_(u'You must be logged on')), my_custom_predicate(msg=l_(u'something wrong'))) def index(self, **kw): return dict() then, my_custom_predicate should check the url paramters for every request in every MyController method, and do whatever it do. The problem is just that: how to allow my_custom_predicate to check the url parameters, using it in that way I wrote above.
