• Not able to connect to TFS Server from TFS Proxy

  - by GV India

  In our office we have setup TFS for project development. The TFS Server is WIN 2003 server SP2 with VSTFS 2008 and is running fine. Now we need to setup a TFS Proxy server on client site for client to access. Before going for the client setup, I wanted to build and test proxy in our office on a dummy server (will call it Proxy server hereon) by keeping it on a different domain. OS configuration of the Proxy server is the same as TFS server. I have installed and configured TFS proxy on Proxy server to connect to TFS Server. Also we have built trust between the two different domains to enable communication. Now problem is that I am not able to at all connect to TFS server. I am trying to connect from Internet Explorer of proxy server using proxy service account. It gives me error: The page cannot be displayed. HTTP 500 - Internal server error. The page I was browsing was http://tfs:8080/VersionControl/v1.0/ProxyStatistics.asmx. I think I have done all the required steps correctly to configure proxy as described in MSDN and also TFS installation guide. Here Proxy service account is a member of ‘Team Foundation Valid Users’ group. I am able to connect to TFS Server (specifying port) using Telnet from command prompt on proxy server as suggested by few sites. The TFS server web sites have been configured to use Integration Windows Authentication. Event Logs on both the servers are also not giving any error. Overall I’m not able to get it done. Any ideas on what might be the problem???

• Need an Overview of Possibilities for multicolumn programming

  - by Sam

  Hi folks, From source1 and source2 i gather that IE9 will NOT support multi-column css3!! Since it is still the most popular browser (another thing i cannot understand), i am left but no other choice than to use Programming Power to make multi-columns work. Now, I use three divs that float to left, and which are manually filled with text. Please don't laugh i know its stupid! But I would wish to not to have to worry about the columns and just have a one piece of (un-interrupted) text which all goes into only 1 div, and then have a program smart enough to split it up into X equally wide columns. Question: before i start reinvent the wheel, what methods of programming power have you known that tackle this elegantly? Please suggest your best working multi-column layout sources so I can evaluate which option is the best (I will update the below table). Exploring all possibilities 2011 and further, to enable multi column text user experience: Language Author SourceCodeUsage WorksOnAllMajorBrowser? ================================================================================= html manual labour put text manually in separate left-floating divs "Y" // Upside: control!

• Zend_Auth and database SaveHandler

  - by takeshin

  I have created Zend_Auth adapter implementing Zend_Auth_Adapter_Interface (similar to Pádraic's adapter) and created simple ACL plugin. Everything works fine with default session handler. So far, so good. As a next step I have created custom Session SaveHandler to persist session data in the database. My implementation is very similar to this one from parables-demo. Seems that everything is working fine. Session data are properly saved to the database, session objects are serialized, but authentication does not work when I enable this custom SaveHandler. I have debugged the authentication and all works fine up till the next request, when the authentication data are lost. I suspected, that is has something to do with the fact, that I use $adapter->write($object) instead $adapter->write($string), but the same happens with strings. I'm bootstrapping Zend_Application_Resource_Session in the first Bootstrap method, as early as possible. Does Zend_Auth need any extra configuration to persist data in the database? Why the authentity is being lost?

• Reporting Services "cannot connect to the report server database"

  - by Dano

  We have Reporting Services running, and twice in the past 6 months it has been down for 1-3 days, and suddenly it will start working again. The errors range from not being able to view the tree root in a browser, down to being able to insert parameters on a report, but crashing before the report can generate. Looking at the logs, there is 1 error and 1 warning which seem to correspond somewhat. ERROR:Event Type: Error Event Source: Report Server (SQL2K5) Event Category: Management Event ID: 107 Date: 2/13/2009 Time: 11:17:19 AM User: N/A Computer: ******** Description: Report Server (SQL2K5) cannot connect to the report server database.

Anyone out there have any ideas on what could be causing these issues? Edit Tried both suggestions below several months ago to no avail. This issue hasn't arisen since, maybe something out of my control has changed....

• Client-Side Dynamic Removal of <script> Tags in <head>

  - by merv

  Is it possible to remove script tags in the <head> of an HTML document client-side and prior to execution of those tags? On the server-side I am able to insert a <script> above all other <script> tags in the <head>, except one, and I would like to be able to remove all subsequent scripts. I do not have the ability to remove <script> tags from the server side. What I've tried: (function (c,h) { var i, s = h.getElementsByTagName('script'); c.log("Num scripts: " + s.length); i = s.length - 1; while(i > 1) { h.removeChild(s[i]); i -= 1; } })(console, document.head); However, the logged number of scripts comes out to only 1, since (as @ryan pointed out) the code is being executed prior to the DOM being ready. Although wrapping the code above in a document.ready event callback does enable proper calculation of the number of <script> tags in the <head>, waiting until the DOM is ready fails to prevent the scripts from loading. Is there a reliable means of manipulating the HTML prior to the DOM being ready? Background If you want more context, this is part of an attempt to consolidate scripts where no option for server-side aggregation is available. Many of the JS libraries being loaded are from a CMS with limited configuration options. The content is mostly static, so there is very little concern about manually aggregating the JavaScript and serving it from a different location. Any suggestions for alternative applicable aggregation techniques would also be welcome.

• Monotouch or Titanium for rapid application development on IPhone?

  - by Ronnie

  As a .Net developer I always dreamed for the possibility to develop with my existing skills (c#) applications for the Iphone. Both programs require a Mac and the Iphone Sdk installed. Appcelerator Titanium was the first app I tried and it is based on exposing some Iphone native api to javascript so that they can be called using that language. Monotouch starts at $399 for beeing able to deploy on the Iphone and not on the Iphone simulator while Titanium is free. Monotouch (Monodevelop) has an Ide that is currently missing in Titanium (but you can use any editor like Textmate, Aptana...) I think both program generate at the end a native precompiled app (also if I am not sure about the size of the final app on the Iphone as I think the .Net framework calls are prelilnked at compilation time in Monotouch). I am also not sure about the full coverage of all the Iphone api and features. Titanium has also the advantage to enable Android app development but as a c# developer I still find Monotouch experience more like the Visual Studio one. Which one would you choose and what are your experiences on Monotouch and Titanium?

• Using JavaMail to send a mail containing Unicode characters

  - by NoozNooz42

  I'm successfully sending emails through GMail's SMTP servers using the following piece of code: Properties props = new Properties(); props.put("mail.smtp.host", "smtp.gmail.com"); props.put("mail.smtp.socketFactory.port", "465"); props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.port", "465"); props.put("mail.smtp.ssl", "true"); props.put("mail.smtp.starttls.enable","true"); props.put("mail.smtp.timeout", "5000"); props.put("mail.smtp.connectiontimeout", "5000"); // Do NOT use Session.getDefaultInstance but Session.getInstance // See: http://forums.sun.com/thread.jspa?threadID=5301696 final Session session = Session.getInstance( props, new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication( USER, PWD ); } }); try { final Message message = new MimeMessage(session); message.setFrom( new InternetAddress( USER ) ); message.setRecipients( Message.RecipientType.TO, InternetAddress.parse( TO ) ); message.setSubject( emailSubject ); message.setText( emailContent ); Transport.send(message); emailSent = true; } catch ( final MessagingException e ) { e.printStackTrace(); } where emailContent is a String that does contain Unicode characters (like the euro symbol). When the email arrives (in another GMail account), the euro symbol has been converted to the ASCII '?' question mark. I don't know much about emails: can email use any character encoding? What should I modify in the code above so that an encoding allowing Unicode characters is used?

• "Subforms" associated with tree view in VB

  - by knomdeguerre

  I am using VB Express 2008 to demonstrate my ideas for an improved UI for an existing product for my colleagues at work. The current UI has a certain page with ten tabs, allowing the user to define up to ten "things". The available choices for each of the ten "things" are all the same. On each of the ten tabs, there is a checkbox to enable that definition. Generally, a user will never use more than 5 or 6 unique definitions, the rest will remain disabled. So far, my prototype has a tree view control with one branch to contain this list of definitions, Add and Delete buttons. My idea is: there is one sub-branch to start with (corresponding to the first tab in the current UI); if the user wants addtional definitions, they click Add and other branches are added to the tree view, up to maximum of ten. I think I should be able to create a "class" that has a sub-UI (like a sub-form in Access) along with behavior code, that can be instantiated with each press of the Add button; each instantiation's settings can be set independently and is displayed in the main UI form )in a panel or frame) when selected in the tree view. For example, suppose the user Adds to make a total of three definitions: the tree view now has three sub-branches, each of which presents the same sub-UI with settings that can be set specific to the selected sub-branch. I'm sure it's possible but not sure how to do it. I know a comprehensive "answer" might be complicated and long, but I may just need some quick hints to get underway - don't be shy! Thanks in advance!

• asp.net C# windows authentication iss config

  - by user1566209

  I'm developing a webpage where a need to know the users windows authentication values, more precisely the name. Others developments have been done with this kind of authentication but sadly for me their creators are long gone and i have no contact or documentation. I'm using Visual Studio 2008 and i'm accessing a webservice that is in a remote server. The server is a windows server 2008 r2 standard and is using ISS version 7.5. Since i have the source code of the other developments what i did was copy paste and was working fine when i was calling the webservice that was in my machine (localhost). The code is the following: //1st way WindowsPrincipal wp = new WindowsPrincipal(WindowsIdentity.GetCurrent()); string strUser = wp.Identity.Name;//ALWAYS GET NT AUTHORITY\NETWORK SERVICE //2nd way WindowsIdentity winId = WindowsIdentity.GetCurrent(); WindowsPrincipal winPrincipal = new WindowsPrincipal(winId); string user = winPrincipal.Identity.Name;//ALWAYS GET NT AUTHORITY\NETWORK SERVICE //3rd way IIdentity WinId = HttpContext.Current.User.Identity; WindowsIdentity wi = (WindowsIdentity)WinId; string userstr = wi.Name; //ALWAYS GET string empty btn_select.Text = userstr; btn_cancelar.Text = strUser; btn_gravar.Text = user; As you can see i have here 3 ways to get the same and in a sad manner show my user's name. As for my web.config i have: <authentication mode="Windows"/> <identity impersonate="true" /> In the IIS manager i have tried lots of combination of enable and disable between Anonymous Authentication, ASP.NET Impersonation, Basic Authentication, Forms Authentication and Windows Authentication. Can please someone help me?? NOTE: The respective values i get from each try are in the code

• joomla and allow_url_fopen [closed]

  - by liz

  so i have been reading of the pros and cons of allowing: allow_url_fopen. but i am still confused. after a recent hacking incident (which i believe had nothing to do with allow_url_fopen) my host turned allow_url_fopen off. so the thing i dont get is, in joomla 2.5.x there is an updating feature.you can search for new versions and be notified if things are out of date. there is a big security hole if joomla or its extensions get out of date. But the catch it needs allow_url_fopen turned on. so why did joomla build a security risk into a feature to improve security??is it okay to turn allow_url_fopen on and have the updating feature? to clarify: my question is. i have Joomla installed. I have CURl installed. when i run the discover updates through NATIVE joomla i get a request for fopen. shouldn't i not need to enable a security risk? i am running version 2.5.8 of joomla.

• Zend Routes conflict

  - by meder

  I have defined 2 custom routes. One for threads/:id/:name and the other for threads/tags/:tagName however the second one conflicts with the first because if I enable both then the first breaks and treats :id literally as an action, not obeying the \d+ requirement ( I also tried using pure regex routes, see bottom ). Action "1" does not exist and was not trapped in __call() I tried re-arranging the order of the routes but if I do that then the threads/tags/:tagName doesnt correctly capture the tagName. I also tried disabling default routes but the routes still don't properly work after that. Here's my route init function: protected function _initRoutes() { $fc = Zend_Controller_Front::getInstance(); $router = $fc->getRouter(); $router->addRoute( 'threads', new Zend_Controller_Router_Route('threads/:id/:name', array( 'controller' => 'threads', 'action' => 'thread', ), array( 'id' => '\d+' ) ) ); $router->addRoute( 'threads', new Zend_Controller_Router_Route('threads/tags/:tagName', array( 'controller' => 'threads', 'action' => 'tags', ), array( 'tagName' => '[a-zA-Z]+' ) ) ); } I also tried using a pure regex route but was unsuccessful, most likely because I did it wrong: $router->addRoute( 'threads', new Zend_Controller_Router_Route_Regex( 'threads/(\d+)/([a-zA-Z]+)', array( 'controller' => 'threads', 'action' => 'thread', ), array( 1 => 'tagName', 2 => 'name' ) ) );

• When an NSWindow object has a delegate that is a NSWindow subclass, who is responsible to act on received events?

  - by spade78

  So I'm building a program that features the use of the IKImageBrowserView component as a subview in an NSWindow. As a side note, I have a controller object called ImageBrowserController which subclasses NSWindow and is set as the delegate of the NSWindow object of my app. I have sent IKImageBrowserView the message setCanControlQuickLookPanel:YES to enable it to automatically use the QuickLook functionality to preview image files when the IKImageBrowserView is a first responder to receive key events. Then it took me a while to figure out how to make the IKImageBrowserView a first responder which I finally got working by overriding acceptsFirstResponder inside my ImageBrowserController. Now I understand that as the delegate to the NSWindow, ImageBrowserController has a place in the responder chain after the event gets triggered on NSWindow. And I understand that as a subview of NSWindow, IKImageBrowserView is in line to be passed events for event handling. What I don't get is where the connection is between the ImageBrowserController being a first responder and the event somehow making it to the IKImageBrowserView. I didn't set NSWindow or IKImageBrowserView as first responders explicitly. So why isn't it necessary for me to implement event handling inside my ImageBrowserController? EDIT: So after reading the accepted answer and going back to my code I tried removing the acceptsFirstResponder override in my ImageBrowserController and the QuickLook functionality still triggered just like the accepted answer said it would. Commenting out the setCanControlQuickLookPanel:YES made the app beep at me when I tried to invoke QuickLook functionality via the spacebar. I'm getting the feeling that my troubles were caused by user error of XCode in hitting the RUN button instead of the BUILD button after making changes to my code (sigh).

• How to get at specific HTML elements of a document using C# and Hide them/Show them etc.

  - by LaserBeak

  Basically I want to load a HTML document and using controls such as multiple check boxes which will be programmed to hide, delete or show HTML elements with certain ID's. So I am thinking I would have to set an inline CSS property for visibility to: false on the ones I want to hide or delete them altogether when necessary. I need this so I don't have to edit my Ebay HTML templates in dreamweaver all the time, where I usually have to scroll around messy code and manually delete or add tags and their respective content. Whereas I just want to create one master template in dreamweaver which has all the variations that my products have, since they are all of the same genre with slight changes here and there and I just need to enable and disable the visibility of these variants as required and copy + paste the final html. I haven's used Windows Forms before, but tried doing this in WebForms which I do know a bit. I am able to get the result that I want by wrapping any HTML elements in a <asp:PlaceHolder></asp:PlaceHolder> and just setting that place holders visibility to false after the associated checkbox is checked and a postback occurs, finally I add a checkbox/button control that removes all the checkboxes, including itself etc for final html. But this method seems just like too much pain in the ass as I have to add the placeholder tags around everything that I need control over as ordinary html elements do not run at server, also webforms injects a bunch of Javascript and ViewState data so I don't have clean HTML which I can just copy after viewing the page source. Any tips/code that you can suggest to achieve the desired effect with the least changes required to existing HTML documents? Ideally I would want to load the HTML document in, have a live design preview of it and underneath have a bunch of well labelled checkboxes programmed to hide, delete or show elements with certain ID's. Thanks...

• jQuery: bind generated elements

  - by superUntitled

  Hello, thank you for taking time to look at this. I am trying to code my very first jQuery plugin and have run into my first problem. The plugin is called like this <div id="kneel"></div> <script type="text/javascript"> $("#kneel").zod(1, { }); </script> It takes the first option (integer), and returns html content that is dynamically generated by php. The content that is generated needs to be bound by a variety of functions (such as disabling form buttons and click events that return ajax data. The plugin looks like this (I have included the whole plugin in case that matters)... (function( $ ){ $.fn.zod = function(id, options ) { var settings = { 'next_button_text': 'Next', 'submit_button_text': 'Submit' }; return this.each(function() { if ( options ) { $.extend( settings, options ); } // variables var obj = $(this); /* these functions contain html elements that are generated by the get() function below */ // disable some buttons $('div.bario').children('.button').attr('disabled', true); // once an option is selected, enable the button $('input[type="radio"]').live('click', function(e) { $('div.bario').children('.button').attr('disabled', false); }) // when a button is clicked, return some data $('.button').bind('click', function(e) { e.preventDefault(); $.getJSON('/returnSomeData.php, function(data) { $('.text').html('<p>Hello: ' + data + '</p>'); }); // generate content, this is the content that needs binding... $.get('http://example.com/script.php?id='+id, function(data) { $(obj).html(data); }); }); }; })( jQuery ); The problem I am having is that the functions created to run on generated content are not binding to the generated content. How do I bind the content created by the get() function?

• How is external memory, internal memory, and cache organized?

  - by goldenmean

  Consider a system as follows:= A hardware board having say ARM Cortex-A8 and Neon Vector coprocessor, and Embedded Linux OS running on Cortex-A8. On this environment, if there is some application - say, a video decoder is executing - then: How is it decided that which buffers would be in external memory, which ones would be allocated in internal SRAM, etc. When one says calloc/malloc on such system/code, the pointer returned is from which memory: internal or external? Can a user make buffers to be allocated to the memories of his choice (internal/external)? In ARM architectures, there is another memory called as Tightly coupled memory (TCM). What is that and how can user enable and use it? Can I declare buffers in this memory? Do I need to see the memory map (if any) of the hardware board to understand about all these different physical memories present in a typical hardware board? How much of a role does the OS play in distinguishing these different memories? Sorry for multiple questions, but i think they all are interlinked.

• Multiple Facebook scripts?

  - by J Set

  This may be kind of a dumb question, but the script for the facebook button on the like button page is different from the script on the javascript sdk page, but similar. Did facebook just forget to update the documentation or do I need both scripts? The like button page gives: <div id="fb-root"></div> <script> (function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> But on the javascript sdk page: <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : 'YOUR_APP_ID', // App ID channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File status : true, // check login status cookie : true, // enable cookies to allow the server to access the session xfbml : true // parse XFBML }); // Additional initialization code here }; // Load the SDK Asynchronously (function(d){ var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); }(document)); </script>

• AppFabric caching's local cache isnt working for us... What are we doing wrong?

  - by Olly

  We are using appfabric as the 2ndlevel cache for an NHibernate asp.net application comprising a customer facing website and an admin website. They are both connected to the same cache so when admin updates something, the customer facing site is updated. It seems to be working OK - we have a CacheCLuster on a seperate server and all is well but we want to enable localcache to get better performance, however, it dosnt seem to be working. We have enabled it like this... bool UseLocalCache = int LocalCacheObjectCount = int.MaxValue; TimeSpan LocalCacheDefaultTimeout = TimeSpan.FromMinutes(3); DataCacheLocalCacheInvalidationPolicy LocalCacheInvalidationPolicy = DataCacheLocalCacheInvalidationPolicy.TimeoutBased; if (UseLocalCache) { configuration.LocalCacheProperties = new DataCacheLocalCacheProperties( LocalCacheObjectCount, LocalCacheDefaultTimeout, LocalCacheInvalidationPolicy ); // configuration.NotificationProperties = new DataCacheNotificationProperties(500, TimeSpan.FromSeconds(300)); } Initially we tried using a timeout invalidation policy (3mins) and our app felt like it was running faster. HOWEVER, we noticed that if we changed something in the admin site, it was immediatley updated in the live site. As we are using timeouts not notifications, this demonstrates that the local cache isnt being queried (or is, but is always missing). The cache.GetType().Name returns "LocalCache" - so the factory has made a local cache. Running "Get-Cache-Statistics MyCache" in PS on my dev environment (asp.net app running local from vs2008, cache cluster running on a seperate w2k8 machine) show a handful of Request Counts. However, on the Production environment, the Request Count increases dramaticaly. We tried following the method here to se the cache cliebt-server traffic... http://blogs.msdn.com/b/appfabriccat/archive/2010/09/20/appfabric-cache-peeking-into-client-amp-server-wcf-communication.aspx but the log file had nothing but the initial header in it - i.e no loggin either. I cant find anything in SO or Google. Have we done something wrong? Have we got a screwy install of AppFabric - we installed it via WebPlatform Installer - I think? (note: the IIS box running ASp.net isnt in yhe cluster - it is just the client). Any insights greatfully received!

• how to allow unamed user in svn authz file?

  - by dtrosset

  I have a subversion server running with apache. It authenticates users using LDAP in apache configuration and uses SVN authorizations to limit user access to certain repositories. This works perfectly. Apache DAV svn SVNParentPath /srv/svn SVNListParentPath Off SVNPathAuthz Off AuthType Basic AuthName "Subversion Repository" AuthBasicProvider ldap AuthLDAPBindDN # private stuff AuthLDAPBindPassword # private stuff AuthLDAPURL # private stuff Require valid-user AuthzSVNAccessFile /etc/apache2/dav_svn.authz Subversion [groups] soft = me, and, all, other, developpers Adding anonymous access from one machine Now, I have a service I want to setup (rietveld, for code reviews) that needs to have an anonymous access to the repository. As this is a web service, accesses are always done from the same server. Thus I added apache configuration to allow all accesses from this machine. This did not work until I add an additional line in the authorization file to allow read access to user -. Apache <Limit GET PROPFIND OPTIONS REPORT> Order allow,deny Allow from # private IP address Satisfy Any </Limit> Subversion [Software:/] @soft = rw - = r # <-- This is the added line For instance, before I add this, all users were authenticated, and thus had a name. Now, some accesses are done without a user name! I found this - user name in the apache log files. But does this line equals to * = r that I absolutely do not want to enable, or does it only allows the anonymous unnamed user (that is allowed access only from the rietveld server)?

• Can a WebServiceHost be changed to avoid the use of HttpListener?

  - by sbyse

  I am looking for a way to use a WCF WebServiceHost without having to rely on the HttpListener class and it's associated permission problems (see this question for details). I'm working on a application which communicates locally with another (third-party) application via their REST API. At the moment we are using WCF as an embedded HTTP server. We create a WebServiceHost as follows: String hostPath = "http://localhost:" + portNo; WebServiceHost host = new WebServiceHost(typeof(IntegrationService), new Uri(hostPath)); // create a webhttpbinding for rest/pox and enable cookie support for session management WebHttpBinding webHttpBinding = new WebHttpBinding(); webHttpBinding.AllowCookies = true; ServiceEndpoint ep = host.AddServiceEndpoint(typeof(IIntegrationService), webHttpBinding, ""); host.Open() ChannelFactory<IIntegrationService> cf = new ChannelFactory<IIntegrationService>(webHttpBinding, hostPath); IIntegrationService channel = cf.CreateChannel(); Everything works nicely as long as our application is run as administrator. If we run our application on a machine without administrative privileges the host.Open() will throw an HttpListenerException with ErrorCode == 5 (ERROR_ACCESS_DENIED). We can get around the problem by running httpcfg.exe from the command line but this is a one-click desktop application and that's not really as long term solution for us. We could ditch WCF and write our own HTTP server but I'd like to avoid that if possible. What's the easiest way to replace HttpListener with a standard TCP socket while still using all of the remaining HTTP scaffolding that WCF provides?

• Rewarding iOS app beta testers with in app purchase?

  - by Partridge

  My iOS app is going to be free, but with additional functionality enabled via in app purchase. Currently beta testers are doing a great job finding bugs and I want to reward them for their hard work. I think the least I can do is give them a full version of the app so that they don't have to buy the functionality themselves. However, I'm not sure what the best way to do this is. There do not appear to be promo codes for in app purchase so I can't just email out promo codes. I have all the tester device UDIDs so when the app launches I could grab the device UDID and compare it to an internal list of 'approved' UDIDs. Is this what other developers do? My concerns: The in app purchase content would not be tied to their iTunes account, so if beta testers move to a new device they would not be able to enable the content unless I released a new build in the app store with their new UDID. So they may have to buy it eventually anyway. Having an internal list leaves a hole for hackers to modify the list and add themselves to it. What would you do?
