• Adobe Air: Read and Write MP3 or JPG from local directory and switch bytes

  - by Max

  I would like to make my local jpg and mp3 files kind of unreadable (without encoding) by just putting the first 100 bytes from the beginning of the file to the end and then saving the file with a .dat extension. I know I have to use the byte array but can't get it work. I would also need then a small function to read that file and put the 100bytes back to the front so that I can play/display the file. It would be great if you could post the whole function because I am quite new to Air so that I fully understand. Thank You!!!!

• Force php through the .net engine in iis7

  - by Rippo

  I have converted a php to asp.net mvc and have it hosted with the Rackspace cloud. All works great apart from some php links are still linked from other sites and within search engines. My question is what do I need to add to my web.config to force php sites to go through the .net engine? These links work as expected as I can catch the 404 and redirect where need be:- http://www.securahome.net/myjunk.info http://www.securahome.net/myjunk.phpp However this one doesn't:- http://www.securahome.net/myjunk.php I have spoken to Rackspace cloud and they say "its not possible as IIS doesn't recognize php files. You can setup mime types to handle them" This however makes no sense and I think they did not understand the problem. Does anyone have a solution?

• System_Daemon and shell_exec

  - by Jesse

  Hey Everyone, I've set up a daemon (daemon.php) using PEAR's System_Daemon which waits for something to appear in the database. Once something is there, the daemon gets enough information and sends it out to another script (execute.php) using the shell_exec command this way I'm not worried about waiting for a response and holding up the daemon. Both of the scripts work fine alone and I'm even able to call shell_exec before calling System_Daemon::start(); . However, if I trying calling it AFTER System_Daemon::start();, then I get an Access Denied only when outputting to a file. I'm still new to Daemons in general, so any ideas or thoughts would be great! Thanks Guys!

• Best way to construct this query?

  - by Andrew

  I have two tables set up similar to this (simplified for the quest): actions- id - user_id - action - time users - id - name I want to output the latest action for each user. I have no idea how to go about it. I'm not great with SQL, but from what I've looked up, it should look something like the following. not sure though. SELECT `users`.`name`, * FROM users, actions JOIN < not sure what to put here > ORDER BY `actions`.`time` DESC < only one per user_id > Any help would be appreciated.

• http://localhost/ not working on Windows 7. What's the problem?

  - by AXheladini

  I have a big problem opening http://localhost/ on Windows 7 (beta). I installed this os and everything went great; when I installed Wamp I saw that localhost is not working at all. I just see this error: Failed to Connect Firefox can't establish a connection to the server at localhost. in Mozilla and Explorer. I removed Wamp and after some weeks (that means two weeks from today) I installed NetBeans on Windows 7. I created a test PHP script and when I debug it, I get the same error again. I tried to access it with ip 127.... but still the same. What is the problem? When i installed NetBeans I installed it in port 8080.

• Can any JavaScript library perform as well as the Cut The Rope JavaScript implementation?

  - by joe

  Now that the canvas tag is starting to get hardware execration [acceleration - thanks guys!] by many browsers, developing casual games in HTML5 is becoming more feasible. ZeptoLabs did a great job porting Cut The Rope to HTML5 for use as a Windows 8 Metro App. You can find some of the details here but they do not get into specifics. I was wondering if anyone knew if they used a library (such as Impact or Crafty) or if you need to write all custom and optimized JavaScript code in order to get this type of performance. Thanks!

• Screen capture during testing

  - by Edwward

  This is an application for reviewing performance tests. Simple in concept, tricky to describe. Picture: 1) Recording interactions with a WPF program so the inputs can be played back. 2) Playing the inputs back while doing a continuous screen capture. 3) Capturing wall time as well as continuous CPU percentages during playback. 4) Repeating steps (2) and (3) lots of times. 5) Writing the relevant stuff out to files/db. 6) Reading it and putting it all in a fancy UI for easy review/analysis. The killer for me is (2). I could use some guidance on a good, possibly commercial, screen capture SDK. I would also welcome the news that my whole problem already has a solution. And of course any thoughts on the overall idea would also be great. Thanks. Ed

• When does innovative software development shows?

  - by den-javamaniac

  I've been working as a software developer for almost a year (not much though) in a corporate environment but all I've done so far is a raw software implementation of company needs. Senior coworkers don't seem to be doing some fairly different stuff. In fact their "benefit" for being experienced is simply an app design and getting their hands on new projects first. My elder software developer friend's jobs don't seem to differ from the overall picture. Currently I'm a student of a CS department and what I really want to bring in this world is some innovative(not new but innovative) stuff that haven't been there. Something as great as google wave or JARVIS (if that can be done at all) or even much better, but yet it looked like that's not possible. The question is: when do people in a corporate environment choose to create something innovative? (from your experience/thoughts)

• Scala Tuple Deconstruction

  - by dbyrne

  I am new to Scala, and ran across a small hiccup that has been annoying me. Initializing two vars in parallel works great: var (x,y) = (1,2) However I can't find a way to assign new values in parallel: (x,y) = (x+y,y-x) //invalid syntax I end up writing something like this: val xtmp = x+y; y = x-y; x = xtmp I realize writing functional code is one way of avoiding this, but there are certain situations where vars just make more sense. I have two questions: 1) Is there a better way of doing this? Am I missing something? 2) What is the reason for not allowing true parallel assignment?

• Advice on simple efficient way to store web form data when no db/auth required

  - by ted776

  Hi, I have a situation where I need to provide an efficient way to process and store comments submitted via a web form. I would normally use PHP and either MySQL or XML to store the data, but this is slightly different in that this web form will only be temporarily available in a closed LAN environment, and all i need to do is process the form data and store it a format which can be accessed by another application on the LAN (Adobe Director). Each request made by the Director app should pop the stack of data. I'm wondering how best to store the data for this type of situation as it's not something I would normally do. I'm thinking possibly storing the data in an XML file, but any advice would be great!

• How to transform html anchor <a> to WordML

  - by Monomachus

  Hi, I need to transform an anchor tag to WordML without using relationships. Is it possible? I found the w: anchor property but seems it refers only to internal document anchors and not to links or URLs. <w:hyperlink w:anchor="chapter3"> <w:r> <w:t>Go to Chapter Three</w:t> </w:r> </w:hyperlink> So it would be great if something similar would be possible to do without making an Id in relationship document and than referring this id from w:hyperlink. Anyone knows something like that?

• How to Test Individual Front End Web Server

  - by ChiliYago

  My farm consists of two front end (FE) web servers that are managed by a load balancer. One FE went down so we configured the load balancer to only send traffic to the other FE. We rebuilt the failed FE and rejoined the farm which appears to have worked successfully (looking at IIS). I want to test the new FE before configuring the Load Balancer to use the new server. The approach I took was to add the IP/URL to my host file that pointed to the new server but nothing comes up. Any advice would be great. Thanks

• Xcode 5 new bug

  - by user2874675

  Since the recent IOS update last month I have been having issues with this new bug that has hampered my program. The bug is as follows: using a UIButton and I want to insert a value into it, only after my execution ends does a letter actually appear. But if I create a method during execution to tell me, using NSLog, what my properties contain then that letter I added never shows up. I'm thinking I need to find a way to refresh a property during execution instead in the end. For example: Let's say you want to insert the letter F into a UIButton. Immediately after writing F into that UIButton, look to see that F hasn't isn't in there. But it will only show up after that particular execution sequence finishes. Any help would be great. Thanks in advance.

• Using NSThread to solve waiting for image from URL on the iPhone

  - by james.ingham

  So I have the following code in a method which I want to set a UIImageView image to that of one from an online source: [NSThread detachNewThreadSelector:@selector(loadImage) toTarget:self withObject:nil]; Then in the method called by the thread I have this: - (void) loadImage { NSURL *url = [NSURL URLWithString:logoPath]; // logoPath is an NSString with path details NSData *data = [NSData dataWithContentsOfURL:url]; logoImage.image = [UIImage imageWithData:data]; } This works great however I get many warnings within the Debugger Console along the lines of: 2010-05-10 14:30:14.052 ProjectTitle[2930:633f] * _NSAutoreleaseNoPool(): Object 0x169d30 of class NSHTTPURLResponse autoreleased with no pool in place - just leaking This occurs many times each time I call the new thread and then eventually, under no pattern, after calling a few of these threads I get the classic 'EXC_BAD_ACCESS' run-time error. I understand that this is happening because I'm not retaining the object but how can I solve this with the code in 'loadImage' shown above? Thanks

• How to convert an Info.plist file from mac os project to iphone project?

  - by Tom Pace

  I am developing an app for the iPhone OS devices, and am using a third-party engine which is not well documented but I've made great progress with it anyway. The problem: The engine's developer strongly urges extending from the existing template projects bundled with the engine, but the engine's Info.plist files are Mac OSX project Info.plist files. This is an iPhone engine, and so I cannot understand why the Info.plist file is structured to take keys for Mac OS apps, but that's how it is. I did a FileMerge comparison to ensure there was nothing within the file itself that defined its use for one OS or the other, so I guess it's defined somewhere in the project settings. Edit - Opening the plist file in Xcode or Property List Editor and then trying to add a key such as "Icon already includes gloss and bevel effects" will not work in this iPhone project because it is not in the list. However, "Cocoa Java Application" and others are available!

• XML jQuery Problem

  - by Llamabomber

  This code for parsing my xml and appending via jquery seems to work great in every browser but Chrome (Mac only, the windows version of chrome works fine) and explorer. I'm not aware of any glaring issues in the code so I thought some fresh eyes might help. Anyone know what could be causing IE and Chrome on the mac to not append? <script type="text/javascript" charset="utf-8"> $(document).ready(function() { $.ajax({ type: "GET", url: "sitenav.xml", dataType: "xml", success: parseXml }); function parseXml(xml) { $(xml).find("GoogleAnalytics").each(function() { $("li#google_analytics").append('<ul><li>' + $(this).find("NavHeader").text() + '</li></ul>'); }); } }); </script>

• wordpress image showing up multiple times

  - by JCHASE11

  I am writing a wordpress theme, and have run into a fairly basic problem. By default, when you inset an image into the post, it displays that image at the size you specify, on both the homepage and the single post. I would like to have different sized images, displaying a thumbnail on the homepage, and a full sized image when you click through to the post. I am using wordpress 2.9's new thumbnail feature, which has created great thumbnails for the homepage. But now, I am stuck with a nice thumbnail next to a large photo (on the index/home page). On the single page, it is displaying correctly with just the large picture. Basically, I need to know how to tell wordpress to only display the large post image on the single page, not on the index. Also: I have used the timthumb script, but I think the answer is far more basic then needing plugins or scripts Thanks!

• Best option for Google App Engine Datastore and external database?

  - by Alex

  I need to get an App Engine app talking to and sharing data with an external database, The best option i can come up with is outputting the external database data to an xml file and then processing this in my app engine app and storing it inside the datastore, although the data being shared is sensitive data such as login details so outputting this to an xml file is not exactly a great idea, is it possible for the app engine app to directly query the database? or is there a secure option for using xml files? oh and im using python/django and the external database will be hosted on another domain

• PHP can't connect to localhost XMPP server on port 5222

  - by Ben Werdmuller

  I've set up an ejabberd install locally on my Windows box, where I also have Apache, PHP and MySQL. I've also confirmed that it works great using Digsby, and have kicked the tires a bit by creating some users, sending some messages, etc. All good. However, PHP can't open a stream using stream_socket_client to port 5222. Even at its simplest level: stream_socket_client("tcp://localhost:5222", $errno, $errstr, 30, STREAM_CLIENT_CONNECT); Returns a timeout error. However, again, connecting with an IM client to localhost on port 5222 works fine. Any ideas? I'm stuck!

• Loading table sections when using headers

  - by Luis Tovar

  I cant seem to wrap my head around this. I have googled, and overstacked for hours now looking for examples that i can relate to. What I have is two arrays. The name of my first NSMutableArray is "showDates". I have 3 objects in here. Object 0: "Today, May 20th" Object 1: "Tomorrow, May 21st" Object 2: "Saturday, May 22nd" Then I have my second NSMutableArray named "showTimes" I have about 15 objects in there with strings in each object. ( i hope that makes sense? ) Each object is structured like this: Object 0: showID @"98022" eventID @"833" showTime @"1:30pm" showDate @"Today, May 20th" auditorium @"9" venue @"2991" Object 1: showID @"98222" eventID @"813" showTime @"2:30pm" showDate @"Tomorrow, May 21st" auditorium @"9" venue @"2991" Etc, etc, .... I have the headers working great in my tableView, but I cant seem to figure out how to add the objects in my "showTimes" array under the correct header. Any help would be greatly appreciated.

• How to make a cell of TAdvStringGrid editable?

  - by ammu

  I am trying to implement a filter using the component TAdvStringGrid. My requirement is that I want the first row of this component to be editable when double clicked, so that the user can filter data. Borland C++ Builder is used to help achieve this task. I found this event OnCanEditCell. TCanEditCellEvent = procedure (Sender:TObject;Arow,Acol:longint;var canedit:boolean) of object; Within this function I've set canedit = true. This doesn't seem to work. Probably I need to do something more. I am new to Windows and GUI development. So any help would be great. Do I need to call this function from the OnDblClickCell event? How can I get it working? Thanks in advance

• Rails 3 beta 1 - Nested layouts - LocalJumpError

  - by Art Shayderov

  Hi Nested layouts do not work in Rails 3. After I hit this I tried Rails Guides Example on a blank project (both ruby 1.9.1 and 1.8.7). LocalJumpError no block given on line <%= yield :stylesheets %. If you remove this line you will get the same error on the next yield statement. Could someone fix(patch) this? It's probably just a matter of calling block_given? in the right place. That would be great. Thanks Added on 4/3: Rails 3 beta 2 released. Problem fixed.

• How do you handle passwords or credentials for standalone applications?

  - by Abel Morelos

  Let's say that you have a standalone application (a Java application in my case) and that this application has a configuration file (a XML file in my case) where you store the credentials (user and password) for a bunch of databases you need to connect. Everything works great, but now you discover (or your are given a new requirement like me) that you have to put this application in a different server and that you can't have these credentials in the configuration files because of security and/or compliance considerations. I'm considering to use data sources hosted in the application server (a WAS server), but I think this could have poor performance and maybe it's not the best approach since I'm connecting from a standalone application. I was also considering to use some sort of encryption, but I would like to keep things as simple as possible. How would you handle this case? Where would you put these credentials or protect them from being compromised? Or how would you connect to your databases in this scenario?
