• ActionScript 3 Context Menu Per Sprite?

  - by TheDarkIn1978

  is it not possible to have different context menus for different sprites on the stage? i've tried adding a custom context menu to a sprite but it's applied to the entire stage: mySprite.contextMenu = myMenu; then after reading the documentation where it states: You can attach a ContextMenu object to a specific button, movie clip, or text field object, or to an entire movie level. You use the menu property of the Button, MovieClip, or TextField class to do this. ok, so i though i had to write it like: mySprite.menu.contextMenu = myMenu; only to be greeted with a nice migration issue stating that menu is legacy code and to use contextMenu instead. ??? um, thanks for the headsup, documentation. this process would be entirely much more easier if i could extend the ContextMenu, but for some reason it's marked as "final" and can't be extended... i'm sure adobe's reasons for finalizing the context menu class are as good as their reasons for including misleading documentation. thoughts?

• MS SQL Server Job with precise timing

  - by TcKs

  Hi, I have a DB with game data (map, players, etc...) and I have a game core mechanics writen in T-SQL stored procedure. I need process game loop (via the stored procedure) every "X" seconds. I tried used the SQL Job, but when I set the interval to seconds, the SQL server stops responding. If I set the interval greater than one minute, all was ok. I need game loop precise in time, e.g. the game loop will run only once and will be executed every "X" precisely (tolerance should be less than one second). Can I do it with MS SQL Server capabilities? Or should I create a windows service which will repeatly execute game loop procedure? Or should I go another way? Thanks! EDIT: The game loop stored procedure takes less than the interval.

• App closes after facebook login in IOS 5

  - by Aromal Sasidharan

  I am using facebook sdk 3.1 framework for my application. The login process works successfully and returns to the app after facebook login both in simulator(iOS 6.0 and 5.0) and in iPad(iOS 6). But When the same is deployed in IPad with IOS 5, after login, it does not return back to my application and shows a blank white Screen or sometimes my application closes. I dont know what went wrong in iOS 5 and facebook sdk 3.1 framework, also i am not getting any logs to debug...

• How do I show the print with AJAX/jQuery?

  - by Doug

  So I'm trying to understand this whole AJAX/jQuery thing. Right now, when I run this PHP script alone, I would have to wait and watch the wheel spin until it's done with the loop and then it will load. while ( $row = mysql_fetch_array($res) ) { postcode_to_storm( $row['Test'] ); $dom = new DOMDocument(); @$dom->loadHTML($result); $xPath = new DOMXPath($dom); $failInvite = 'Rejected'; $findFalse = strpos($result, $failInvite); if ( $findFalse == true ) { $array[$i] = $row['Test']; $i++; echo $array[$i]}; } } Now, how do I use AJAX/jQuery to show echo $array[$i]}; everytime it is invoked instead of waiting for the whole process to complete?

• is it good practice to use iframe to implement header/navbar?

  - by Xah Lee

  is it good practice to use iframe to implement header/navbar? my website is basically 5 thousand pages but all static html (not using any content manager, php, etc.). am in the process to add a navbar at the top of each page. e.g. tabs, or crumbs, or any sort of header with js menu. (the exact design not decided yet) my question is, is it good practice to use a iframe for this? (so, instead have same text repeated in all 5 thousand pages, each will just have a short iframe pointing to a header file) am aware that one should reduce http request for speed, but this is ok with me. Any other problems i might have with this? SEO or any tech issue?

• better for-loop syntax for detecting empty sequences?

  - by Dmitry Beransky

  Hi, Is there a better way to write the following: row_counter = 0 for item in iterable_sequence: # do stuff with the item counter += 1 if not row_counter: # handle the empty-sequence-case Please keep in mind that I can't use len(iterable_sequence) because 1) not all sequences have known lengths; 2) in some cases calling len() may trigger loading of the sequence's items into memory (as the case would be with sql query results). The reason I ask is that I'm simply curious if there is a way to make above more concise and idiomatic. What I'm looking for is along the lines of: for item in sequence: #process item *else*: #handle the empty sequence case (assuming "else" here worked only on empty sequences, which I know it doesn't)

• How not to lose focus on a login page

  - by Misha Moroshko

  I have a simple login form with 2 input fields: "username" and "password". "username" field is focused by default. The problem is that when user clicks outside "username" or "password" fields, the focus is gone (it is neither on "username" nor on "password" fields"). How can I force the focus to be on these 2 fields only ? In my case, this is a really annoying behavior, so I really want to do this :) Can I do something like: $("*").focus(function() { if (!$(this).hasClass("my_inputs_class")) { // How to stop the focusing process here ? } }); ?

• How can I set the Rails environment for my somewhat stand alone Ruby script?

  - by Nick

  I have a Ruby script in my Rails app that I use to load some data from Twitter. In the future I will make it an automatic background process, but for now I run it manually like: ruby /lib/twitter/twitterLoad.rb In order to use the Rails model classes and such, I have the following as the top line of the script: require "#{File.dirname(__FILE__)}/../../config/environment.rb" By default, the development environment is used. But, I'd like to be able to choose the production environment at some point. Update #1: The RAILS_ENV constant is getting set in the environment.rb file. So, I was able to put ENV['RAILS_ENV'] = 'production' at the very top (before the environment.rb) line and solve my problem somewhat. So, my new question is, can do pass in env vars through the command line?

• Visual C++ 9 Linker file size limitation.

  - by Raindog

  It appears that the visual C++ 9 linker has a file allocation algorithm that doubles the size of the file every allocation, so you get 512mb, 1024mb, 2048mb, 4096mb. The problem is that it is using a library that cannot handle files larger 2048MB, and as such crashes with an error such as "cannot read file at is the disk full or write protected". Is there a way to bypass this limitation or otherwise replace the linker with something else that works? A bit of background, I have a code generator that generates a large number of files, ~15k cpp files, I've managed to reduce the number of files to something about 6k to get something that at least completes the linking process, I would like to be able to include all 15k without having to create multiple libs.

• File synck tool with network support (FTP or SSH) and decent GUI

  - by Álvaro G. Vicario

  Is there a decent GUI tool for Windows that allows to publish files from/to a remote FTP (or SFTP) server with the same ease of use that WinMerge offers in local discs? I'll basically use it to upload changes to web sites. I've tried like a dozen tools and they're all terrible. They have difficult interfaces, you need to spend ten minutes configuring absurdly complicate project settings, there's no simple way to ignore specific files or they use custom databases that break when someone else uploads files—not to mention deployment frameworks that force you to script everything in their custom language. I don't need or even want to schedule or automate. I want a manual process I can review. I'm tired of picking files one by one in Filezilla while reading the Subversion logs. I'd love an open source tool but...

  - by roa3

  I am using PHP, AS3 and mysql. I have a website. A flash(as3) website. The flash website store the members' information in mysql database through php. In "members" table, i have "id" as the primary key and "username" as a unique field. Now my situation is: When flash want to display a member's profile. My questions: Should Flash pass the member "ID" or "username" to php to process the mysql query? Is there any different passing the "id" or "username"? Which one is more secure? Which one you recommend? I would like to optimize my website in terms of security and performance.

• Ignoring characters in a file while parsing

  - by sfactor

  i need to parse through a text file and process the data. the valid data is usually denoted by either a timestamp with TS followed by 10 numbers (TS1040501134) or values with a alpabet followed by nine numbers (A098098098)...so it will be like TS1040501134A111111111B222222222...........TS1020304050A000000000........ However, there are cases when there will be filler 0s when there is no data. So, such a case might be 00000000000000000000TS1040501134A111111111B2222222220000000000TS1020304050A000000000........` Now as we can see I need to ignore these zeros. how might i do this? I am using gnu C.

• how to use proxy with JSON

  - by Dele

  I have a php page called 'dataFetch.php' which sits on one webserver. On another webserver, I have a JS file which issues JSON calls to dataFetch. dataFetch connects to a database, retrieves data and puts it in a JSON format which is fed back to the calling program. In IE, this works fine. In other browsers it does not because of the cross domain restriction. To get across the cross-domain restriction, I make a call to a file, proxy.php, which then makes the call to dataFetch. My problem now is that proxy.php retrieves the file from dataFetch but the JS script file no longer sees the response from proxy.php as a JSON format and so I can't process it. Can anybody help me out?

• Prevent content with child nodes from being deleted in umbraco

  - by Soldarnal

  I would like to prevent content nodes from being trashed if they have any children. I setup an event handler like so: public class KeepSafeEvents : ApplicationBase { public KeepSafeEvents() { Document.BeforeMoveToTrash += new Document.MoveToTrashEventHandler(Document_BeforeMoveToTrash); } void Document_BeforeMoveToTrash(Document sender, umbraco.cms.businesslogic.MoveToTrashEventArgs e) { if (sender.HasChildren) { e.Cancel = true; } } } However, this doesn't seem to work. I assume it is because the delete process moves the child nodes to trash first before dealing with the parent node (which then has no children). Is there another possible solution? Or am I making a simple mistake above?

• Generics and reflection in Java

  - by Ragesh

  This is probably a very basic question, but I'm really new to generics in Java and I'm having a hard time altering my thought process from the way things are done in C#, so bear with me. I'm trying to build a generic repository in Java. I've created an IRepository interface that looks like this: public interface IRepository<T extends IEntity> And a Repository class that looks like this: public class Repository<T extends IEntity> implements IRepository<T> Now, from within the constructor of my Repository class, I'd like to be able to "divine" the exact type of T. For example, if I instantiated a repository like this: IRepository<MyClass> repo = new Repository<MyClass>(); I'd like to know that T is actually MyClass. This is trivial in C#, but obviously generics are a totally different beast in Java and I can't seem to find anything that would help me do this.

• Expiring an IE session using WatiN

  - by Steve Wilkes

  I'm trying to write an acceptance test using WatiN which checks that a user is redirected to the login page if they navigate to a page after their session times out. I'm using WatiN's IE class for the browser, and trying the following: // 1. Login // 2. Do this: Browser.ClearCookies(); Browser.ClearCache(); // 3. Navigate to a different page But the user is always still logged in. Other info: I'm running the test through the NUnit GUI running as an administrator It's an ASP.NET MVC 3 site, using forms authentication and in-process session state I'm using IE9. If I manually clear all cookies in Chrome, the user is logged out If I manually clear all cookies in IE the user stays logged in If I call Browser.Eval("alert(document.cookie)"); in IE it alerts an empty string Given the above, I'm assuming this is a quirk with IE; any ideas how I can work around it?

• Millisecond-Accurate Scheduling of Future Events in C++/CLI

  - by A Grad Student at a University

  I need to create a C++/CLI mixed assembly that can schedule future calls into a native DLL with millisecond accuracy. This will, of course, mean setting a timer (what kind?) for a millisecond or three beforehand, then spinning until the moment and calling the native DLL function. Based on what I've read, I would guess that the callback that the timer calls will need to be native to make sure there are no thunks or GC to delay handling the timer callback. Will the entire thread or process need to be native and CLR-free, though, or can this be done just as accurately with #pragma unmanaged or setting one file of the assembly to compile as native? If so, how? If there is indeed no way to do this in mixed-mode C++/CLI, what would be the easiest way to set up an app/thread (ie, DLL or exe?) to handle it and to get the data back and forth between the native and managed threads/apps?

• Good overview tool / board for visualizing Subversion branch acitivity?

  - by Sam

  Our team is sometimes finding it a bit confusing and time-consuming to figure out which subversion operations have been perrformed on our different branches in Subversion. Example, when has the Development branch last been merged into the Trunk? When was this particular Tag created, based on what branch etc etc. All of this information can of course be extracted from the Subversion Log, but thats always a manual, time-consuming and error-prone process. Simplest solution seems to be a simple whiteboard with a visualization of all the different branches/tags/trunk in Subversion and people drawing on it, whenever something significant happens. But we're not averse to finding some kind of a digital solution as well, stored centrally. Obviously both systems depend on people actually maintaining the model, but you'll always more or less have that. What do you use as best practice for keeping a clear view on all Subversion operations in the current Sprint (or beyond)?

• Automate downloads from password protected website

  - by Andrew

  I need some help with a work project I have been assigned. At the moment we manually go to the site, logon and then download 2 excel files from a supplier's website every month. The files are then loaded into SQL. We want to automate this process. Now the loading of the files into SQL I can do, but I am not sure how I can automate logging onto the website entering my user details and collecting the files. I mostly deal with SQL and have very little .NET experience, so any code samples would be most appreciated.

• Reverse engineering a custom data file

  - by kerchingo

  At my place of work we have a legacy document management system that for various reasons is now unsupported by the developers. I have been asked to look into extracting the documents contained in this system to eventually be imported into a new 3rd party system. From tracing and process monitoring I have determined that the document images (mainly tiff files) are stored in a number of 1.5GB files. These files seem to be read from a specific offset and then written to a tmp file that is then served via a web app to the client, and then deleted. I guess I am looking for suggestions as to how I can inspect these large files that contain the tiff images, and eventually extract and write them to individual files.

• Java Thread - Synchronization issue

  - by Yatendra Goel

  From Sun's tutorial: Synchronized methods enable a simple strategy for preventing thread interference and memory consistency errors: if an object is visible to more than one thread, all reads or writes to that object's variables are done through synchronized methods. (An important exception: final fields, which cannot be modified after the object is constructed, can be safely read through non-synchronized methods, once the object is constructed) This strategy is effective, but can present problems with liveness, as we'll see later in this lesson. Q1. Is the above statements mean that if an object of a class is going to be shared among multiple threads, then all instance methods of that class (except getters of final fields) should be made synchronized, since instance methods process instance variables?

• checkbox selected value is lost after coming back to the pagei.e., viewstate value is lost with use

  - by M.Vijay bhasker

  In the left navigation i have a series of check boxes and a grid view in the page body.Grid view results changes based on the check box selection,whenever i click on the links in grid view it goes to the second page and there is a link on the page which takes me back to the first page,but the check box selected value is maintained for the first time only and if we repeat the same process for the second time and i see that the first time selection of the check box is maintained.Here the grid view is placed in update panel and the check box in the left is called using .... AsyncPostBackTrigger ControlID="cphLeftNavigation". I've tried removing the above code referring the cphLeftNavigation and i see the results are coming up correctly and the last selected check box value is being maintained correctly and i want the same functionality to be implemented with/without update panel. Can anyone let me know,what exactly should i change to implement the above mentioned functionality.

• Referencing surrogate key

  - by Arman

  I have a table that has an autoincrement surrogate key. I want to use it as a foreign key of my other table. The thing is, I cant figure out how I can reference it to that table, because it is nearly impossible to determine what I have to reference(the actual value of the surrogate key). Please be noted that what I am trying to do is adding a tuple/record through my program(outside the dbms). The process is: Add a new record in Table1 and generate an autoincrement key. Update Add a new record in Table2 and reference its foreign key to the primary key of Table1. Update My question is : HOW do I store the foreign key if I didnt know what is it?

• C++ coverage tool that WORKS?!

  - by Poni

  Been searching for a good coverage tool for a while now. I'm with VC++ 2008. Tried already: NCover, PureCoverage, PartCover and a few others I can't remember their names. None works! Not even with a very basic console application that does almost nothing. Tried to get an evaluation copy from BullsEye and few more others - not only that they require you to ask for it (no automatic process), they don't even answer after you request AND after you ask what's going on, through the support mail. So the question is: Is there any tool, which I can immediately download an evaluation for it, that actually works on VC 2008 projects? Something that will get me going within 10 minutes? It's funny but it seems to be a very non-trivial request in the area of this kind of software.
