  • Pass parameters to Flash Main (Document) class

    - by loto
    In Flash CSn/AS3 you associate a Main class with a flash file which when loaded in the flash player "automatically creates an instance of the program's main class." I'd like to know how to pass arguments to the main class, since you don't write it yourself (you put its name in the Document textfield in the IDE).

    - by Ankit
    Hi All, I have to include a dynamic page content into my template, Say I have a left panel which gets the data dynamically through a view. Now, I have to include this left panel into all my pages but I do not want to duplicate the code for all the pages. Is there any way, I can write a single script and include it in all my templates to display the left panel in all my pages? Thanks in advance.

  • Not sure what happens to my apps objects when using NSURLSession in background - what state is my app in?

    - by Avner Barr
    More of a general question - I don't understand the workings of NSURLSession when using it in "background session mode". I will supply some simple contrived example code. I have a database which holds objects - such that portions of this data can be uploaded to a remote server. It is important to know which data/objects were uploaded in order to accurately display information to the user. It is also important to be able to upload to the server in a background task because the app can be killed at any point. for instance a simple profile picture object: @interface ProfilePicture : NSObject @property int userId; @property UIImage *profilePicture; @property BOOL successfullyUploaded; // we want to know if the image was uploaded to out server - this could also be a property that is queryable but lets assume this is attached to this object @end Now Lets say I want to upload the profile picture to a remote server - I could do something like: @implementation ProfilePictureUploader -(void)uploadProfilePicture:(ProfilePicture *)profilePicture completion:(void(^)(BOOL successInUploading))completion { NSUrlSession *uploadImageSession = ..... // code to setup uploading the image - and calling the completion handler; [uploadImageSession resume]; } @end Now somewhere else in my code I want to upload the profile picture - and if it was successful update the UI and the database that this action happened: ProfilePicture *aNewProfilePicture = ...; aNewProfilePicture.profilePicture = aImage; aNewProfilePicture.userId = 123; aNewProfilePicture.successfullyUploaded = NO; // write the change to disk [MyDatabase write:aNewProfilePicture]; // upload the image to the server ProfilePictureUploader *uploader = [ProfilePictureUploader ....]; [uploader uploadProfilePicture:aNewProfilePicture completion:^(BOOL successInUploading) { if (successInUploading) { // persist the change to my db. aNewProfilePicture.successfullyUploaded = YES; [Mydase update:aNewProfilePicture]; // persist the change } }]; Now obviously if my app is running then this "ProfilePicture" object is successfully uploaded and all is well - the database object has its own internal workings with data structures/caches and what not. All callbacks that may exist are maintained and the app state is straightforward. But I'm not clear what happens if the app "dies" at some point during the upload. It seems that any callbacks/notifications are dead. According to the API documentation- the uploading is handled by a separate process. Therefor the upload will continue and my app will be awakened at some point in the future to handle completion. But the object "aNewProfilePicture" is non existant at that point and all callbacks/objects are gone. I don't understand what context exists at this point. How am I supposed to ensure consistency in my DB and UI (For instance update the "successfullyUploaded" property for that user)? Do I need to re-work everything touching the DB or UI to correspond with the new API and work in a context free environment?

  • Sorting a 2 dimensional array on multiple columns

    - by Anon
    I need to sort a 2 dimensional array of doubles on multiple columns using either C or C++. Could someone point me to the algorithm that I should use or an existing library (perhaps boost?) that has this functionality? I have a feeling that writing a recursive function may be the way to go but I am too lazy to write out the algorithm or implement it myself if it has been done elsewhere. :-) Thanks

  • Why doesn't every, and I mean it, language have this feature?

    - by dada
    Some time ago I had a look into Ruby and one of the things which stood out most for me was the way of using symbols. While you to use defines or strings like in C++ or Python as an alternative, in Ruby you just write :mySymbol and the interpreter takes over the enumeration for you. I can't see any disadvantage this feature has, so why is it missing in say, PHP and Python?

  • Creating new folders if they don't exist for fopen

    - by Gbps
    I have a C++ program that takes user input for fopen in order to initiate a file write. Could someone help me find a function which will return a FILE* and use the Windows specific version of mkdir in order to create the folder structure for fopen to never fail to open a new file in the specified location because one of the folders does not exist. Thanks a bunch!

  • @property setter for BOOL.

    - by George
    Hi, I'm having problems setting a BOOL using @property and @synthesize. I'm using @property BOOL isPaused; And I can get it by using [myObject isPaused]; but I cannot manage to set it. I'd like to use [myObject setPaused: NO];. I also tried @property (setter=setPaused) BOOL isPaused; but if I'm not mistaking, then I need to write that setter myself.

  • Why isnt int pow(int base, int exponent) in the standard C++ libraries?

    - by Dan O
    I feel like I must just be unable to find it. Is there any reason that the c++ pow function does not implement the "power" function for anything except floats and doubles? I know the implementation is trivial, I just feel like I'm doing work that should be in a standard library. A robust power function (ie handles overflow in some consistent, explicit way) is not fun to write.

  • How do I create a deb package with basic dependencies?

    - by Sam
    Hi so I am trying to create a deb package for a web application written in Java (it uses Apache Tomcat). My eventual goal is to start a repository that people can add to apt-get the software, but How do I make it so that the package knows to look for dependencies like tomcat, sun-java6-bin, and ant? How do I write an installer script to place the files and folders in the right place?

  • Is there way to determine if a file has been executed or not in C#?

    - by Shane
    I'm looking for a way to determine if a file has been executed or not. I've looked a bit into FileInfo's LastAccessTime but this doesn't seem to change when a file is executed. I've also looked into FileSystemWatcher but this also doesn't seem to offer a solution. Is there such a thing as a file execution listener or is there another way? If it helps, i'm looking to write a folder listener that renames an .avi file within it after it has been watched/executed.

  • Oracle - Return shortest string value in a set of rows

    - by Sridhar
    Hi, I'm trying to write a query that returns the shortest string value in the column. For ex: if ColumnA has values ABCDE, ZXDR, ERC, the query should return "ERC". I've written the following query, but I'm wondering if there is any better way to do this? BTW, the query should return a single value. select distinct ColumnA from ( select ColumnA, rank() over (order by length(ColumnA), ColumnA) len_rank from TableA where ColumnB = 'XXX' ) where len_rank <= 1 Thank you.
