• How to automatically email customers registration keys?

  - by Danny

  I've written a bit of software that I'd like to share with others (a Mac Dashboard widget, specifically), but I'd also like to be compensated a bit for the time I spent on it. I've devised my own simple registration key algorithm, which takes a customer's email address and creates a 12-character alphanumeric key. The software itself is finished, demo limitations, key validation & all. I just need to get the keys to customers. How do I simply alert a key generation script to automatically email a customer a key, upon notification that they paid my account? Can I use PayPal IPN & JavaScript? The simplest solution will do - this is a five dollar widget. :)

• How do I rewrite binary data in Java

  - by hayato

  I'm trying to figure out how to replace binary data using Java. below is a PHP example of replacing "foo" to "bar" from a swf file. <?php $fp = fopen("binary.swf","rb"); $size = filesize("binary.swf"); $search = bin2hex("foo"); $replace = bin2hex("bar"); $data = fread($fp, $size); $data16 = bin2hex($data); $data16 = str_replace($search, $replace, $data16); $data = pack('H*',$data16); header("Content-Type:application/x-shockwave-flash"); echo $data; ?> How do I do this in Java.

• Google Maps API v3... non-mobile?

  - by andrhamm

  I'm trying to make a Google Maps widget for my website but all of the examples are for full-screen mobile devices. The tutorials work when I copy paste them exactly as shown but they don't seem to work when I want them to only occupy a portion of the page. From what I've read, the v3 is the best API yet (for what I need) because of its speed and compatibility with mobile devices. I plan to make a widget very similar to the MarkerClusterer example from the demo gallery but I can't get it working. Is this a common issue? I know I'm being vague but I would appreciate some help. Thanks

• Weak reference and Strong reference

  - by theband

  package uk.co.bigroom.utils { import flash.utils.Dictionary; /** * Class to create a weak reference to an object. A weak reference * is a reference that does not prevent the object from being * garbage collected.

• Best way to auto-restore a database every hour

  - by aron

  I have a demo site where anyone can login and test a management interface. Every hour I would like to flush all the data in the SQL 2008 Database and restore it from the original. Red Gate Software has some awesome tools for this, however they are beyond my budget right now. Could I simply make a backup copy of the database's data file, then have a c# console app that deletes it and copies over the original. Then I can have a windows schedule task to run the .exe every hour. It's simple and free... would this work? I'm using SQL Server 2008 R2 Web edition I understand that Red Gate Software is technically better because I can set it to analyze the db and only update the records that were altered, and the approach I have above is like a "sledge hammer".

• Linux application that bundles multiple incoming audio and video streams into one container file?

  - by StackedCrooked

  I've been assigned to implement a video on-demand service for a local university. Different aspects of the lectures (video, audio, screen cast, white board) will be recorded. During a lecture all these data streams arrive at one Linux server. This server should transcode and bundle all these streams into one container (Matroska) file. My options seem to be: Write a GStreamer application do something with FFMPEG do something with VLC ...? Has anyone done something similar in the past? Can you recommend something? Edit For those interested, here are a few of my findings: Matroska is not a good format for streaming (it's possible, but it's not its primary intent) For Flash streaming you can use MPEG4 If you want to combine different videos into one video where each subvideo occupies a rectangular portion of the total screen, then this GStreamer script is useful (I found it on this blog post). Desktop capture works fine with VLC

• errors with gae-sessions and nose

  - by Kekito

  I'm running into a few problems with adding gae-sessions to a relatively mature GAE app. I followed the readme carefully and also looked at the demo. First, just adding the gaesesions directory to my app causes the following error when running tests with nose and nose-gae: Exception ImportError: 'No module named threading' in <bound method local.__del__ of <_threading_local.local object at 0x103e10628>> ignored All the tests run fine so not a big problem but suggests that something isn't right. Next, if I add the following two lines of code: from gaesessions import get_current_session session = get_current_session() I get the following error: Traceback (most recent call last): File "/Users/.../unit_tests.py", line 1421, in testParseFBRequest data = tasks.parse_fb_request(sr) File "/Users/.../tasks.py", line 220, in parse_fb_request session = get_current_session() File "/Users/.../gaesessions/__init__.py", line 36, in get_current_session return _tls.current_session File "/Library/.../python2.7/_threading_local.py", line 193, in __getattribute__ return object.__getattribute__(self, name) AttributeError: 'local' object has no attribute 'current_session' Any suggestions on fixing the above would be greatly appreciated.

• Flex: client / server messaging question (RPC or socket ?)

  - by Patrick

  hi, I'm building a Flex application, which is going to perform many server requests (let's say, that almost all interactions require an update from server). At the moment I'm using remote procedure calls for it. But I was wondering if using a socket would be better. In other terms, is maybe better to keep the connection alive rather then performing many calls in sequence ? For my demo app I only have 1 client. Is the number of clients connecting to the server a factor for this choice ? thanks

• iOS - playing a youtube video from a webview thumbnail

  - by soleil

  Was about to finally submit an app when I realized that the youtube videos I'm playing play from the iPhone, but not the iPad. Here's the code I'm using: NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: transparent;\ color: white;\ }\ </style>\ </head><body style=\"margin:0\">\ <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"></embed>\ </body></html>"; NSString *html = [NSString stringWithFormat:embedHTML, [videoItem objectForKey:@"URL"], thumb.frame.size.width, thumb.frame.size.height]; UIWebView *videoView = [[UIWebView alloc] initWithFrame:thumb.frame]; [videoView loadHTMLString:html baseURL:nil]; [videoContainer addSubview:videoView]; Is there any reason this would work on the iPhone and not the iPad? I'm testing on a 1st generation iPad. The videos play on both iPhone models I've tested (3GS and 4S). Nothing happens at all when I tap on the webviews on the iPad.

• Using finch first time. How to play mp3,ogg or other formats (wav files to big) ?

  - by Allisone

  My *.wav's work as expected. But wav files are to big, so I want to play *.mp3 or *.ogg but it doesn't work. I use this lines of code found in the finch Demo project engine = [[Finch alloc] init]; sitar = [[Sound alloc] initWithFile:RSRC(@"sitar.wav")]; [sitar play]; So I only change sitar.wav into my .mp3 filename. Note 1: It mustn't be mp3 or ogg, any file format not as huge as wav should be ok, but which ? Note 2: I didn't know how to use sound, so I searched and found finch here at stackoverflow. It looks easy, so I would like to use that, but if you know some other easy way to play that sound files (ambient + effects sound with compressed codec) I would also switch to that other technique.

• Load external swf from a button in external swf and unload self?

  - by ChristinaR

  Hello, I am an uber n00b to flash AS3. And it is not my intention to sound like a complete moron, but honestly, I have had a hard enough time figuring out just how to load an external .swf into my main file! And now my friend is asking me if I could please add a button within the external .swf which will unload itself and load a new on in its place... I have looked around in the forums for an answer for a while now and I believe it is time for me to break down, admit defeat, and ask for help. Can someone please tell me it's not that difficult..? Surely it is possible... Thank you in advance for any advice at all! I am looking forward to the time when I can post a response here!

• jquery hover menu question

  - by vondip

  Hi all, I am developing a small web app that uses jquery quite a lot. In my app a user can hover an image, which becomes bigger after a few seconds, giving him more details. The problem is that when the image enlarges the image, it takes over the area of the nearby images as well. Now, if the user goes over the second red square (numbered as 2) I would like the currently enlarged image to disappear and instead enlarge the image pictured below as square two. I am not much of a painter, but I have attached a small image to help illustrate the problem. In short, How can I tell jquery to detect when the mouse is over red square number two, yet not raising the event if the mouse is over green square. [in my demo picture, hovering on point]

• Accessing a Clip Inside Another Clip in a Loaded SWF-File

  - by Anders

  I'm writing a card game in AS3. The artist I'm working with has produced (in Flash CS4) a single swf-file containing all the card graphics and animations. The structure of the fla working file looks something like this: - Scene - CardGraphics (Movie Clip) - CardFront - CardBack - CardValueImage (Movie Clip) ... In the program I create 52 instances of my Card class, each having a MovieClip instance created from the loaded swf. The idea is to set the frame of the CardValueImage MovieClip to correspond to the Card instance's suit and rank member variables. However, I can't figure out how I access CardValueImage and call gotoAndStop (or whatever method I will need to call). This is basically what I want to do: // Card Class [Embed(source = 'CardGraphics.swf')] private static var CardsClip:Class; private var clip:MovieClip = new CardsClip; // Card Constructor this.valueImageFrame = suit * 13 + rank; // Calculate which frame contains the // graphical representation of this card this.clip.CardValueImage.gotoAndStop(valueImageFrame);

• Creating a standalone ASP.NET MVC application for Windows XP

  - by Robert Harvey

  Is there a way to create an installable (ideally XCopy installable) version of an ASP.NET MVC application that will run in a standalone fashion on a Windows XP machine? I don't mind installing SQL Server Express for this purpose, so I guess the question boils down to this: Can the Cassini web server that comes with Visual Studio 2008 be bundled with the application? Or are there other options? NOTE: The installation is for demo purposes only, so there are no licensing problems. Also, I am suggesting Cassini because I don't know of a way to install IIS7 on Windows XP. I can't do major hackage on the registry to get this to work.

  I have a current web build with a right sidebar that is a fixed position. I have tried to positioning from the right but don't want it overlapping other divs content. What I am looking for is to have the content scrollable horizontally to the right when it is out of the viewport window. Any help would be greatly appreciated. similarly to this: http://demo.rickyh.co.uk/css-position-x-and-position-y/ however I can not get this working. This has been solved by alternative method. Thanks for those who actually considered helping.

• Incompatible classes when loading SWF

  - by Bart van Heukelom

  I have two ActionScript 3 projects, game(.swf) and minigame(.swf). At runtime the main game loads the minigame via Loader. I also have a shared library (SWC) of event classes, included by both, which minigame will need to dispatch and game will need to listen to. First: Is this possible this way? Second: What will happen if I compile the minigame, then change the event classes so they're incompatible, then compile the main game. Will Flash crash when trying to load the minigame SWF? (I hope so) Third: And what will happen if I change the event classes, but in a way that preserves interface-level compatibility?

• AS3: creating a class with multiple and optional parameters?

  - by redconservatory

  I'm creating a slideshow where each slide can have: - a video or a still - 1 audio track or many (up to 3) - 1 button or many (up to 3) I was thinking that each slide can be it's own object, and then I would pass the video, audio, buttons, etc., into it as parameters: package { import flash.media.Video; public class Section { public function Section (video:Video, still:myPhotoClass, audiotrack:Sound, button:myButtonClass) { // can have video OR a still // can have 1 audio track or several // can have 1 button or more } } I'm not sure how to go about approaching this since there can be multiples of certain items (audio, buttons) and also two items are sort-of-optional in the sense that there can be ONE or the OTHER (video/still). For example, is this something that I should just avoid passing as parameters altogether, using a different approach (getters/setters, maybe)?

• Debug Linux kernel pre-decompression stage

  - by Shawn J. Goff

  I am trying to use GDB to debug a Linux kernel zImage before it is decompressed. The kernel is running on an ARM target and I have a JTAG debugger connected to it with a GDB server stub. The target has to load a boot loader. The boot loader reads the kernel image from flash and puts it in RAM at 0x20008000, then branches to that location. I have started GDB and connected to the remote target, then I use GDB's add-symbol-file command like so: add-symbol-file arch/arm/boot/compressed/vmlinux 0x20008000 -readnow When I set a breakpoint for that address, it does trap at the correct place - right when it branches to the kernel. However, GDB shows the wrong line from the source of arch/arm/boot/compressed/head.S. It's 4 lines behind. How can I fix this? I also have tried adding the -s section addr option to add-symbol-file with -s .start 0x20008000; this results in exactly the same problem.

• Can you explain this odd behavior with dragging items into nested sortables?

  - by RDL

  I have the following setup: A sortable list where one of the <li> has a table with lists in each cell. All of the lists are sortable with each other. Draggable items that can be added to any of the sortables Issue: When adding a draggable item ('drag 1', 'drag 2', 'drag 3') to one of the lists in the horizontal lists (table of lists) it duplicates the draggable when dropped. Sometimes it will create both copies in the same list or one in the item list and one in the column list. Here is a demo: http://jsfiddle.net/MQTgA/ Question: How do I prevent the second item being created when dropping the draggable?

• keypress event not being triggered only at start and end of text field in Firefox (JQuery)

  - by rlivsey

  I'm listening for keypress events on an input field with delegation. For some reason, Firefox doesn't trigger the delegated event for cursor UP when at the start of the field, or cursor DOWN when at the end. LEFT and RIGHT work as expected all the time. Directly binding an event listener to the field works fine, so it has to be something to do with delegation. Does anyone know if this is a know issue, I couldn't find anything on Google/forums etc..? $("div").delegate(":input", "keypress", function(e){ // doesn't get triggered }); $("div :input").bind("keypress", function(e){ // gets triggered fine }); Here's a demo which shows the issue - http://livsey.org/jquery.delegation.html

• VB.net WebBrowser and AJAX List Options

  - by Vinsick

  I'm writing a VB.net program for a website that uses the AJAX Lits options http://www.ajaxdaddy.com/demo-dhtml-autocomplete.html Whats more is that the website has used additional arguments in the function that i'm not exactly sure what they are calling, and there a trigger that executes an action that must be click, tabbing and returning fail. Any idea on how to automate this? This website has been a holy terror since it was unleashed on my company. I've tried this: Dim ObjArr(4) As Object ObjArr(0) = CObj("prac_select") ObjArr(1) = CObj("'getCountriesByLetters'") ObjArr(2) = CObj("1") ObjArr(3) = CObj("'prac_name'") ObjArr(4) = CObj("'practice'") WebBrowser1.Document.InvokeScript("ajax_showOptions", ObjArr)
