  • Can ANYONE get _lockroot to work?

    - by webfac
    Hi Guys, I have the following code which ultimately loads a SWF into movieclip 'myloader' using a movie clip loader, code as follows: var myload:MovieClipLoader = new MovieClipLoader(); var listener:Object = new Object(); myload.addListener(listener); listener.onLoadStart = function(){ animcontainer.myloader._lockroot = true; trace("Started"); } listener.onLoadInit = function(){ animcontainer.myloader._lockroot = true; trace("finished and locked"); } listener.onLoadComplete = function(){ animcontainer.myloader._lockroot = true; } myload.loadClip(path, animcontainer.myloader); The swf I am loading has pause, rewind and play buttons that must be referencing _root as they work fine when played alone. Upon loading them into myloader they no longer work. Based on the above code surely the myloader clip should be locking as _root after the load is complete? I have Googled myself dry on this one, no luck. ANY help will be much appreciated, Thanks.

  • Error handling with Python + Pylons

    - by ensnare
    What is the proper way to handle errors with Python + Pylons? Say a user sets a password via a form that, when passed to a model class via the controller, throws an error because it's too short. How should that error be handled so that an error message gets displayed on the web page rather than the entire script terminating to an error page? Should there be any error handling in the controller itself? I hope I am explaining myself clearly. Thank you.

  • MySQL LEFT JOIN issue with three WHERE statements

    - by jhat
    I am building a note taking app for myself with tag filtering functions, but am having an issue when trying to grab notes with the tags. The tag filter needs to use AND not IN, because it will help better narrow down what I am looking for. My tables are configured like this: + notes note_id | note_title | note_uid + tags tag_id | tag_title + notes_tags nt_id | nt_note_id | nt_tag_id The notes_tags table keeps track of all notes' tags. I am not worried about returning any information about tags, so here is an example LEFT JOIN I am using currently to only get notes with only 1 tag. SELECT * FROM notes_tags LEFT JOIN notes ON note_id = nt_note_id WHERE note_uid IN ( 1 ) AND nt_tag_id = 10 This query runs perfect, it grabs all of the notes with that single tag. However, I am having issues "pinpointing" my notes using a query like this: SELECT * FROM notes_tags LEFT JOIN notes ON note_id = nt_note_id WHERE note_uid IN ( 1 ) AND nt_tag_id = 10 AND nt_tag_id = 11 What am I doing wrong with the syntax?

  • SVN access/security concern

    - by user167850
    I'm considering using a third party hosting company to house an SVN repository. (I'm looking at Dreamhost but this may apply to other hosts as well.) The hosting company sets up the repository at http://svn.yourdomain.com/path. The problem I have noticed is that anyone could come along and export the files using: svn export http://svn.yourdomain.com/path Obviously I will need to export the files myself, but is there a way to secure this on a shared host so others don't have the ability to export this over http? Or is the real solution to manage your own SVN server? Thanks for your thoughts.

  • How do I get the key of an item when doing a FOR loop through a dictionary or list in Python?

    - by Mike Hayes
    Hi I am new to Python. Say I have a list: list = ['A','B','C','D'] The key for each item respectively here is 0,1,2,3 - right? Now I am going to loop through it with a for loop... for item in list: print item That's great, I can print out my list. How do I get the key here? For example being able to do: print key print item on each loop? If this isn't possible with a list, where keys are not declared myself, is it possible with a Dictionary? Thanks

  • Passing a NSString to another ViewController using classes

    - by Jeff Kranenburg
    I know this insanely simple, but I am re-teaching myself the basics and trying to get my head around this:-) I have one ViewController called MainVC and I have one called ClassVC In ClassVC I have this code: @interface ClassVC : UIViewController { NSString *mainLine; } @property (nonatomic, retain) NSString *mainLine; @end and I have this in the implementation file: @synthesize mainLine = _mainLine; -(NSString *)_mainLine { _mainLine = @"This a string from a Class"; return _mainLine; } Now I was thinking that if I #import the ClassVC into MainVC I would be able to transfer that string along as well like so: This code is in the viewDidLoad _mainLabel.text = _secondClass.mainLine; NSLog(@"%@", _secondClass.mainLine); But that is not working - so cannot I not pass strings in through this way???

  • Go to file in Visual Studio

    - by Effata
    I've recently started a new job working with webdevelopment in .NET. Coming from a php and rails background i've been working mainly in Eclipse and NetBeans, along with some TextMate. I find myself missing a few great keyboard shortcuts and i can't seem to find a Visual Studio equivalent. NetBeans has the awesome "Go To File" and so does Eclipse with this plugin. Eclipse also has the option of quick searching in the open file list with Cmd/Ctrl-E. Is there something like this in Visual Studio? Either build in or via plugin. Or is there some other way of quickly navigating between files that's prefered?

  • Can JQuery/JavaScript be used to write a substantial client side application?

    - by Ian
    I have an unusual situation - I have an embedded video streaming device with a complicated UI, and I need to use an embedded web server to reproduce that UI through a web browser. I'm thinking of using JavaScript/JQuery on a C++ backend (I am NOT coding all this myself, I need to hire people for the grunt work). The embedded web server is much less powerful than a PC, so I want to write an application that runs the entire UI in the browser, and only communicates with the server to pass new program settings back and forth, get status updates from the device, and control video playback. In other words, the client gets one big page or a small number of big pages (effectively downloading the application), the application maintains significant local memory storage, and once the pages are first loaded the server never sends anything layout-related. The application has two rows of tabs to navigate ~40 menu pages, drag-and-select controls to pick cells in a grid, sorted lists, lots of standard data entry options, and it should be able to control up to 16 embedded video players at once (preferably VLC). Is this possible in JavaScript/JQuery with a C++ backend?

  • C++ STL: Array vs Vector: Raw element accessing performance

    - by oh boy
    I'm building an interpreter and as I'm aiming for raw speed this time, every clock cycle matters for me in this (raw) case. Do you have any experience or information what of the both is faster: Vector or Array? All what matters is the speed I can access an element (opcode receiving), I don't care about inserting, allocation, sorting, etc. I'm going to lean myself out of the window now and say: Arrays are at least a bit faster than vectors in terms of accessing an element i. It seems really logical for me. With vectors you have all those security and controlling overhead which doesn't exist for arrays. (Why) Am I wrong? No, I can't ignore the performance difference - even if it is so small - I have already optimized and minimized every other part of the VM which executes the opcodes :)

  • Rotating Viewbox contents smoothly

    - by user204562
    I'm looking to teach myself better methods of doing things in WPF that I would normally do manually. In this case, I have a ViewBox with an image in it. I also have a button that uses a DoubleAnimation to rotate the image 90 to the right. This animation works fine, but obviously because it's square as it turns, the image does a "best fit" to the ViewBox which makes the rotation look quite bad, as it gets larger and smaller as its longest edge shrinks or grows to fit to that particular rotation angle. I am looking for any advice on the best way to handle this using appropriate WPF methods. Obviously I could do all the calculations manually, but I would be more interested in finding a way to use the controls and methods built into the .NET architecture. Thanks for your help.

  • HTML to automatically hide text depending on scrolled size (like in Gmail)?

    - by Stephen Cagle
    Look at your Gmail inbox. You have 3 main columns contains the Sender contains "THE_EMAIL_SUBJECT - THE_EMAIL_BODY" the date the email was sent on I note that when you resize the window, the Gmail web client automatically resizes the displayed text in the second column. It basically just truncates the text so that it always can display the sent on date to the right, and the sender to the left. It is a pretty neat effect, and I would like to have that effect for myself. Does anyone know how to do this in HTML/CSS/JS?

  • How can I edit a js file sent by the server before it gets to my browser?

    - by pstone
    During a normal browsing session I want to edit a specific javascript file before the browser receives since once it gets there it's impossible to edit. Is there are any tool for this? For what I need it I can't just save it and edit it on my disk. I'm ready to learn how to program it myself but if anyone can point out more or less what I have to do I'd be very grateful. I'd have to intercept the packets until I have the whole file while blocking the browser from receiving it any part of it, then edit it manually and forward it to the same port. I don't think I can do this by just using pcap, I've read a bit about scapy but I'm not sure if it can help me either. Thanks in advance.

  • In what package should a "Settings" class be placed?

    - by Tom
    I'm in the middle of building an application but found myself too easily creating new packages without keeping the project's structure in mind. Now, I'm trying to redo the whole project structure on paper first. I am using a Settings class with public properties, accessed as settings for several other classes around the project. Now, since this Settings class applies for the whole project, I am unsure if it should be packaged and if so, in what kind of package should it exist? Or should it be in the root (the default package) with the main application class? I've been thinking about putting it in my utils package, then again I don't think it really is an utlity. Any strategies on how to decide on such package structure for example for a Settings class?

  • How to complete a git clone for a big project on an unstable connection?

    - by LaPingvino
    I am trying to git clone the LibreOffice codebase, but at the moment I have an internet connection by mobile phone of about 300kbps and it's just anything but stable. I can get the connection back any moment, but then the git clone process already stopped working, and no way to get it running again. Is there some way to have a more failure-resistant git clone download? One option I considered myself is to download someone else's .git directory, but that is overly dependent of others and doesn't seem like the best possible solution to me.

  • What's the most performance effective way to have a webbrowser inside a class library ?

    - by Xaqron
    I'm developing a class library. Need some data from internet and this cannot be done with HttpWebRequest in my case so I wanna use WebBrowser component. WebBrowser is used for opening a single page and fetch some data from it, so WebBrowser life-time is very short. Running thread is MTA and no message pump or STA thread is available by default (class library is used by an ASP.NET application). How to create a WebBrowser object, run it with a STA thread, fetch data from a web page and finally dispose it with the least performance impact on the application ? I just need the idea/concept and will find details myself. Thanks guys

  • Anyway to surround code block with curly braces {} in VS2008?

    - by Jim McKeeth
    I always find myself needing to enclose a block of code in curly braces { }, but unfortunately that isn't included in the C# surround code snippets, which seems to be an oversight. I couldn't find anything on building your own surround snippets either (just other kinds of snippets). I am actually running Resharper too, but it doesn't seem to have this functionality either (or I haven't figured how to activate it). We have a coding standard of including even a single line of code after an if or else in curly braces, so if I could just make Resharper do that refactor automatically that would be even better!

  • What is the correct way to fix this Javascript closure

    - by sujoe
    I have been familiarizing myself with javascript closures and ran across this article http://blog.morrisjohns.com/javascript_closures_for_dummies.html Due to the closure, Example 5 does not work as expected. How would one modify result.push( function() {alert(item + ' ' + list[i])} ); to make the code work? function buildList(list) { var result = []; for (var i = 0; i < list.length; i++) { var item = 'item' + list[i]; result.push( function() {alert(item + ' ' + list[i])} ); } return result; } function testList() { var fnlist = buildList([1,2,3]); // using j only to help prevent confusion - could use i for (var j = 0; j < fnlist.length; j++) { fnlist[j](); } } testList(); Thanks!

  • Does this interface already exist in the standard .NET libraries?

    - by VoidStar
    I found myself needing a simple generic interface, and I wrote it, but it turned out to be pretty much the world's simplest interface. I was wondering if it already exists by some other name. I just want to make sure I'm not reinventing something that is already included with the .NET framework. interface IReceiver<T> { void Receive(T obj); } I can't really find a good list of "standard" interfaces that came with .NET. Does the structure of this interface look familiar to anyone? Have I reinvented something that is already standard? EDIT: I have a data object and a number of objects interested in receiving the data. Objects interested in receiving the data implement the interface, so that 'routing' lists and maps can send the data to them. The idea is full generalization in the routing, the routing will be data-driven.

  • DLL Load Failed: %1 is not a valid win32 application

    - by glittershark
    So I have a situation where I need to make binary patches and then be able to apply them from within python. I found bsdiff which looks like a great algorithm and has a python extension module, but that extension module doesn't have a windows installer past Python 2.5 Alright, so having never even written C seriously, let alone attempted a python extension module, I set out to compile it myself. After a few hours of bashing my head against a DLL load error with MinGW32, I managed to get it compiled and built using the setup.py provided in the source of the project. However, upon importing the resulting bsdiff module, I get: ImportError: DLL load failed: %1 is not a valid Win32 application. Any advice?

  • Object initialization sequence in Objective-C

    - by Alex
    Hello everyone. The Cocoa framework has a convention to always call self = [super init] in the init method of an inherited class, because [super init] may return a new instance. What will happen if I do this? @interface MyClass : NSObject /* or any other class */ { int ivar_; } @end @implementation MyClass - (id)init { ivar_ = 12345; if ((self = [super init])) { NSLog(@"ivar_'s value is %d", ivar_); } return self; } @end In the case when [super init] returns a new instance, what will I see in the console? ivar_'s value is 0? I can't think of a way to check this myself, because I don't know which class may return a new instance from its init method. Also, can't seem to find explicit clarification for this scenario in the docs. Could anyone help me out? Thanks!

  • Fastest method for SQL Server inserts, updates, selects

    - by Ian
    I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

  • Zoom controls not showing when using a MapView with fill_parent

    - by Joe
    Hey everyone I am working on an applications and I am using the built in zoom controls. When using a specific size I can see the zoom controls. When using fill_parent the zoom controls are not visible. How it is setup is a mapview inside of a frame layout(also using fill parent for the height and width but with an offset down the screen. The only thing I can think of is the fill parent issue is with the framelayout and the zoom controls are off the screen. Sorry if this is confusing, I confused myself writing it. Thanks in advance

  • Best practices for storing & selecting time/date with php & mysql?

    - by Adam
    I often find myself storing data in a mysql database, and then wanting to display all sorts of stats about my data, specifically stuff like 'how many rows do I have for this date, or that date'. Does anyone know of (or could write) a good tutorial on this subject? Ideally a good tutorial would overview: Best practices when storing the data (i.e. what formats to use, how to use them servertime vs. generated time, etc.) Best practices when selecting data from the database with php (i.e. how to sort rows by date, how to retrieve only rows from a certain date, or a certain hour, etc).. Timezones and other issues that might come up. Thanks in advance.

  • While programming, what to do when facing with a seemingly unsolvable situation with a time limit?

    - by Ersan Tasan
    This is not a technical question, but rather a social and methodical one. I am a computer sciences student and I usually have really tough programming assignments. I don`t know if it is only happening to me but sometimes, particularly when deadline is approaching, i find myself in a harsh situation. I cannot find my mistake in the code or come up with a another great idea. Then boredom comes in and the problem begins to seem unsolvable. I know there are more-than-great professional coders here. I would like to learn their ideas to cope with this situation. Is it better to focus on something else for a while and try again or try harder and harder and look for the solution on the net etc...

  • What do you name your files when using MVC?

    - by sprugman
    When using the MVC pattern, which I'm not terribly experienced with, I find myself naming things like this: /app/views/widget.php /app/models/widget.php /app/controllers/widget.php That appeals to me because it's easy to find associated classes, and I lean towards shorter names when practical. However, when I'm looking in my IDE, I see three different files called widget.php, which is confusing. I'm tempted to add "_v", "_c", "_m" or something to each name. How do you handle this? FWIW, I'm using CodeIgniter at the moment, and I don't know if there are any special benefits to using a particular convention, or any standard practices. Regardless, I'm intersted in the best-practices from various platforms.
