  • Parameter to swf loaded with loader class

    - by alejandrobog
    Hi im loading a child swf into my parent swf and I want to pass some parameters to the child swf. Any idea on how to do this. Here is my code: var req:URLRequest = new URLRequest( "test.swf" ); var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener( Event.COMPLETE, loadComplete ); loader.load(req); function loadComplete(e:Event){ var childSwf:DisplayObject = e.target.content as DisplayObject; //Im guessing here I need to set the parameter VideoContainer.addChild(childSwf); }

  • Using delegate Types vs methods

    - by Grant Sutcliffe
    I see increasing use of the delegate types offered in the System namespace (Action; Predicate etc). As these are delegates, my understanding is that they should be used where we have traditionally used delegates in the past (asynchronous calls; starting threads, event handling etc). Is it just preference or is it considered practice to use these delegate types in scenarios such as the below; rather than using calls to methods we have declared (or anonymous methods): public void MyMethod { Action<string> action = delegate(string userName { try { XmlDocument profile = DataHelper.GetProfile(userName); UpdateMember(profile); } catch (Exception exception) { if (_log.IsErrorEnabled) _log.ErrorFormat(exception.Message); throw (exception); } }; GetUsers().ForEach(action); } At first, I found the code less intuitive to follow than using declared or anonymous methods. I am starting to code this way, and wonder what the view are in this regard. The example above is all within a method. Is this delegate overuse.

  • Evaluating creation of GUI via file vs coding

    - by nevets1219
    I'm working on a utility that will be used to test the project I'm currently working on. What the utility will do is allow user to provide various inputs and it will sends out requests and provide the response as output. However, at this point the exact format (which input is required and what is optional) has yet to be fleshed out. In addition, coding in Swing is somewhat repetitive since the overall work is simple though this should be the safest route to go as I have more or less full control and every component can be tweaked as I want. I'm considering using a configuration file that's in XML to describe the GUI (at least one part of it) and then coding the event handling part (in addition to validation, etc). The GUI itself shouldn't be too complicated. For each type of request to make there's a tab for the request and within each tab are various inputs. There seems to be quite a few questions about this already but I'm not asking for a 3rd party library to do this. I'm looking to do this myself, since I don't think it'll be too overly complicated (hopefully). My main consideration for using this is re-usability (later on, for other projects) and for simplifying the GUI work. My question is: are there other pros/cons that I'm overlooking? Is it worth the (unknown) time to do this? I've built GUI in VB.NET and with Flex3 before.

  • what is the purpose of getEventType() method in XMLStreamReader Class

    - by KItis
    I have sample code written for parsing xml file using javax.xml package. it uses the method called getEventType() , but I can not understand the purpose of this method. i wrote simple application to understand its usefulness, but it output only some random numbers for which I can not make any sense, could some one help me to get this point right. Here is the sample code I have written. public List parseXML(File f) throws XMLStreamException{ xmlInputFactory = new WstxInputFactory(); xmlInputFactory.setProperty(XMLInputFactory2.IS_REPLACING_ENTITY_REFERENCES, Boolean.FALSE); xmlInputFactory.setProperty(XMLInputFactory2.IS_SUPPORTING_EXTERNAL_ENTITIES, Boolean.FALSE); xmlInputFactory.setProperty(XMLInputFactory2.IS_COALESCING,Boolean.FALSE); xmlInputFactory.setProperty(XMLInputFactory2.IS_VALIDATING,Boolean.FALSE); xmlInputFactory.configureForSpeed(); List<Task> tasks = new LinkedList<Task>(); //xmlStreamReader = xmlInputFactory.createXMLStreamReader(new StringReader(dmml)); xmlStreamReader = xmlInputFactory.createXMLStreamReader(f); int eventType = xmlStreamReader.getEventType(); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); /*String currentElement = ""; String currentElementText = ""; }

  • Comparison question string vs int

    - by Mike
    Can someone explain to me why these comparisons work they way the do. I had a bug in one of my scripts that took me a little bit to work through. I was using read-host and typing a number. It was storing it as a string. Write-Host "(`'2`' -gt 9 ) = " ('2' -gt 9 ) Write-Host "(2 -gt 9 ) = " (2 -gt 9 ) Write-Host "(`'2`' -gt 10 ) = " ('2' -gt 10 ) If you are comparing a string to an Int does it use the Ascii value? If so why does the first one show $false, it should be $true. Then how is it when you chage it to an int of 10 it because $true.

  • Flash browser game - HTTP + PHP vs Socket + Something else

    - by Maurycy Zarzycki
    I am developing a non-real time browser RPG game (think Kingdom of Loathing) which would be played from within a Flash app. At first I just wanted to make the communication with server using simply URLLoader to tell PHP what I am doing, and using $_SESSION to store data needed in-between request. I wonder if it wouldn't be better to base it on a socket connection, an app residing on a server written in Java or Python. The problem is I have never ever written such an app so I have no idea how much I'd have to "shift" my thoughts from simple responding do request (like PHP) to continuously working application. I won't hide I am also concerned about the memory and CPU usage of such Server app, when for example there would be hundreds of users connected. I've done some research. I have tried to do some research, but thanks to my nil knowledge on the sockets subject I haven't found anything helpful. So, considering the fact I don't need real time data exchange, will it be wise to develop the server side part as socket server, not in plain ol' PHP?

  • Excel Merge() vs MergeCells

    - by sleepp
    Hi, I'm using VSTO, C#, and Excel but VBA probably applies here as well. What's the difference between calling the Merge(missing) method on a range and setting the MergeCells property to true? Does Merge() fail more often? Thanks!

  • MPICH2 vs KERRYGHED

    - by user311906
    Hi All right now I am moving first steps in clustering. I installed MPICH2 on my Ubuntu at home and I have a silly question about it. For what I am reading right now it seems that it provides the capability of sending processes to other pcs. I went for this lib just because I set it up very quickly and easily. Compared to MPICH2 , do you know what is the advantage of having a different clustering system like KERRYGHED? It seems that these ones also provide this capability, but the Kernel must be rebuild, so I suppose that it is going to be faster. What other advantages are remarkable for a clustering system like this? Thanks

  • Using Variables for Class Names in Python?

    - by Sam McAfee
    I want to know how to use variables for objects and function names in Python. In PHP, you can do this: $className = "MyClass"; $newObject = new $className(); How do you do this sort of thing in Python? Or, am I totally not appreciating some fundamental difference with Python, and if so, what is it?

  • Monitor vs Watch on SourceForge Tracker

    - by Vulcan Eager
    What exactly is the difference Watching and Monitoring a project on the SourceForge Tracker UI? PS: The tool tips are really helpful. Hold your mouse over the "Monitor" button and it says "Monitor this project"... hold it over "Watch" and it says nothing. That's really awesome coming from SF.

  • Simple C++ container class that is thread-safe for writing

    - by conradlee
    I am writing a multi-threaded program using OpenMP in C++. At one point my program forks into many threads, each of which need to add "jobs" to some container that keeps track of all added jobs. Each job can just be a pointer to some object. Basically, I just need the add pointers to some container from several threads at the same time. Is there a simple solution that performs well? After some googling, I found that STL containers are not thread-safe. Some stackoverflow threads address this question, but none that forms a consensus on a simple solution.

  • PHP image resize on the fly vs storing resized images

    - by Pablo
    I'm building a image sharing site and would like to know the pros and cons of resizing images on the fly with php and having the resized images stored. Which is faster? Which is more reliable? how big is the gap between the two methods in speed and performance? Please note that either way the images go through a PHP script for statistics like views or if hotlinking is allow etc... so is not like it will be a direct link for images if i opt to store the resize images. I'll appreciated your comments or any helpful links on the subject, Thanks.

  • Debugging ASP.NET in VS

    - by negligible
    A lot of what I'm doing at the moment is figuring out other peoples code and adding or adapting functions, so currently I am debugging more than I am writing code of my own. I'm still new to this, Junior Developer, and I am always finding new ways to improve what I am doing. For example I recently found This Guide which had some excellent tips, such as overriding the ToString() method in your classes so children are readable from their parents. So I am looking for any other tips or tricks to make my debugging more efficient, as I recognise it as a big part of programming, that you more experienced programmers may have picked up or found. Anything appreciated, I can read websites just fine so no need to explain it yourself if you have a good link!

  • CodeIgniter static class question

    - by Josh K
    If I would like to have several static methods in my models so I can say User::get_registered_users() and have it do something like public static function get_registered_users() { $sql = "SELECT * FROM `users` WHERE `is_registered` = 0"; $this->db->query($sql); // etc... } Is it possible to access the $this->db object or create a new one for a static method?

  • .NET: bool vs enum as a method parameter

    - by Julien Lebosquain
    Each time I'm writing a method that takes a boolean parameter representing an option, I find myself thinking: "should I replace this by an enum which would make reading the method calls much easier?". Consider the following with an object that takes a parameter telling whether the implementation should use its thread-safe version or not (I'm not asking here if this way of doing this is good design or not, only the use of the boolean): public void CreateSomeObject(bool makeThreadSafe); CreateSomeObject(true); When the call is next to the declaration the purpose of the parameter seems of course obvious. When it's in some third party library you barely know, it's harder to immediately see what the code does, compared to: public enum CreationOptions { None, MakeThreadSafe } public void CreateSomeObject(CreationOptions options); CreateSomeObject(CreationOptions.MakeThreadSafe); which describes the intent far better. Things get worse when there's two boolean parameters representing options. See what happened to ObjectContext.SaveChanges(bool) between Framework 3.5 and 4.0. It has been obsoleted because a second option has been introduced and the whole thing has been converted to an enum. While it seems obvious to use an enumeration when there's three elements or more, what's your opinion and experiences about using an enum instead a boolean in these specific cases?

  • domain name vs ip address, same server, but different speed

    - by bn
    I have two similar sites: - two of them have almost exactly the same codes, and running on the same server - both sites are the same, they just use different language. - database of the slower site is populated (maybe only the user table) the other tables for site content is the same - the faster uses root to access database one of the sites is not released yet, so it uses IP Address to access the site instead of domain name the site that is using IP address is faster (lot faster) the site that is using domain name is slower do you know why is this happening what could be the reason?
