• How to make an Asp.net MVC 2 website have a Private Beta Mode.

  - by Mark Kitz

  I am creating an ASP.Net MVC website that I am launching soon in private beta. What I am using. ASP.NET MVC 2 ASP.NET Sql Membership Provider Authorization Attributes on ActionMethods. ex. [EditorsOnly] What I am trying to accomplish: During the private Beta period of my website, I want no anonymous users to access my site. Only Beta Testers of my site should be able to login and use my site as normal. After the private beta period people can access it using the security structure I already have set up. I am hoping I do not have to recompile but can have a setting in the webconfig to switch between Private Beta mode to Normal mode. Thanks for your suggestions.

• Long polling with NSURLConnection

  - by pix0r

  I'm working on an iPhone application which will use long-polling to send event notifications from the server to the client over HTTP. After opening a connection on the server I'm sending small bits of JSON that represent events, as they occur. I am finding that -[NSURLConnectionDelegate connection:didReceiveData] is not being called until after I close the connection, regardless of the cache settings I use when creating the NSURLRequest. I've verified that the server end is working as expected - the first JSON event will be sent immediately, and subsequent events will be sent over the wire as they occur. Is there a way to use NSURLConnection to receive these events as they occur, or will I need to instead drop down to the CFSocket API? I'm starting to work on integrating CocoaAsyncSocket, but would prefer to continue using NSURLConnection if possible as it fits much better with the rest of my REST/JSON-based web service structure.

• Can FileOutputStream() take a relative path as an argument

  - by Ankur

  I am creating a FileOutputStream object. It takes a file or String as an argument in its constructor. My question is, can I give it a relative URL as an argument for the location of a file, it doesn't seem to work, but I am trying to work out if this is possible at all (if not I will stop trying). If it is not possible, how can I (from a servlet) get the absolute path (on the filesystem, not the logical URL) to the current location in such a way that I can pass that to the constructor. Part of my problem is that my dev box is Windows but I will publish this to a Unix box, so the paths cannot be the same i.e. on Windows C:/.... and on unix /usr/...

• Preventing spam bots on site?

  - by Mike

  We're having an issue on one of our fairly large websites with spam bots. It appears the bots are creating user accounts and then posting journal entries which lead to various spam links. It appears they are bypassing our captcha somehow -- either it's been cracked or they're using another method to create accounts. We're looking to do email activation for the accounts, but we're about a week away from implementing such changes (due to busy schedules). However, I don't feel like this will be enough if they're using an SQL exploit somewhere on the site and doing the whole cross site scripting thing. So my question to you: If they are using some kind of XSS exploit, how can I find it? I'm securing statements where I can but, again, its a fairly large site and it'd take me awhile to actively clean up SQL statements to prevent XSS. Can you recommend anything to help our situation?

• Regarding Visual C# MenuItem: Where does the NullReference come from?

  - by Thomas

  Hi All. I have a problem creating MenuItems for a TreeView dynamically: here is the (simplified)code i'm using. public class CTM : TreeNode, IComparable, IComparable<CTM> { public CTM(CTMProvider provider) { this.provider = provider; this.manager = provider.manager; this.IEEEAddress = provider.IEEEAddress; this.endpoint = provider.state._conn.RemoteEndPoint; this.Text = String.Format("CTM: {0} {0}", IEEEAddress, ((System.Net.IPEndPoint)endpoint).ToString()); try { MenuItem meni = System.EventHandler(this.provider.Disconnect)); this.ContextMenu.MenuItems.Add(meni); } catch { Trace.TraceError("Could not create menu item!"); } } } This code always triggers the catch clause with a NullReferenceException. Any Ideas?

• ria entity remove bug

  - by Greg

  hello, I am trying out the ria services and I am experiencing this problem that seems very strange to me. I am creating a new entity of type "House" and add it to context without saving the context so the id of the new entity is 0, after i remove this entity and add another new entity of type "House" again and again without saving the context, here comes the weird part, now I have an entity of type "City" which holds entityset of all "Houses" in that city, so to put the newly created entity "House" into the city i do something like this - house.City = city, where house is type "House" and city is type "City", afte this step a check the context and suddenly there are 2 entities of type "House" with id 0, one of them is the one I have deleted at the beginning. Any idea what is causing this and how to fix it?? thank you Greg

• 2008 Datacenter Word Automation issue

  - by Brad

  We have an application that uses word automation. It works fine under Windows XP, but does not work on our Windows Server 2008 64-bit virtual machine running on VMware ESX unless it is running as the domain administrator. Under any other account (including a local admin), Word starts, uses a lot of CPU for 40 seconds when opening a document, and then just hangs. Our application does not access anything not on the local machine, and this machine is not being used for anything else (not a domain controller, etc). I know others have posted similar issues, with the solution of creating a Desktop folder somewhere under the windows directory. We did this, and it did not solve the problem (Word did not get as far as it did before we did this though). Please don't turn this into a thread about why I am trying to do this, whether I should do this, or whether I need to. For argument sake, I don't need to do this, but understanding what privilege a local admin does not have that is needed to do this is a legitimate concern.

• Get C# Templates For VS 2008 Shell

  - by Onorio Catenacci

  I've got VS 2008 Shell Integrated mode; I've got F# 2.0 on that installation. Till now this has worked fine for me because I've been hacking at F# code. Now though, I want to install Intellifactory's WebSharper. It looks like the Intellifactory templates assume that C# templates will be available because while it will create the F# portion of the solution it will not create the Web project in the solution with the complaint A problem was encountered creating the sub project 'Web Application'. The template specified cannot be found. Is there any place where I can get the C# stuff to add to this instance of VS 2008 Shell? Apologies in advance if this is a dup question but I've googled without much luck and I don't seem to find this here either. I've seen that about devenv /installvstemplates but that also fails with a message about needing to elevate privileges (which is odd since I try it under an admin user).

• IIS7 301 Redirect from a List of URLs

  - by corymathews

  Recent changes are forcing me to add a bunch of 301 redirects. Seems that IIS7 is my best bet as compared to redirects within the files. I have found how to add them 1 by 1 but this requires the page/folder to exist (which most don't anymore(and creating them seems to defeat the point of the redirect)) and does not work on dynamic urls. I also cannot go to every page and add the redirects at the page level because some older pages are in php which is no longer supported on the new server. There is also no obvious pattern to the changes so each one must be made on its own. samples of the redirects page.htm - /page/ /folder/folder/ - /folder/folder.cfm /folder/folder/ - /folder/ /page.php?id=1 - page.htm

• HTML5: Can't drag on-the-fly created <div> tag even though draggable='true' Do I need to "BLESS"

  - by Pete Alvin

  After creating a div on the fly with this markup: $('.circuit').prepend("<div class='component' draggable='true'>TRANSISTOR</div>"); It is NOT draggable itself :( Is jQuery prepend() the correct way to create "live" tags in the DOM? Do I need to somehow bless it a different way to make draggable=true really work? How to I wire it up so that on-the-fly divs can be draggable? AFTER NOTE: I added a static div and that is draggable. INTERESTING: I view both the static and dynamic using FireFox F12 Firebug and they are identical. But one is draggable and one is not!!!

• Custom capistrano task for working with scm repository

  - by Trevor

  Is there any way to create a custom capistrano task for performing other actions on a scm repository? For instance, I would like to create a task that will checkout a particular folder from my repository and then symlink it into the shared/ directory of the main project on my server. I know this can be done by creating a task and explicity defining the "svn co ..." command along with the scm username, password, and repository location. But this would display the password in plain text. Are there any built-in capistrano variables/methods that would help in this process?

• How do I get a reference to the current project in an Eclipse plugin?

  - by Martin Doms

  I'm creating an editor for Eclipse. Right now the editor fires up with the user creates a new file with the appropriate extension. My question is, how can I get a reference to the project in which the file resides? For example, say I have a workspace with 2 projects, P1 and P2. I right click P2 and create a new file, can I get a reference to P2 from this somehow? Ultimately I need to reference the AST or Java Model of the project but even a String identifying the project would work.

• Assembly Version Conflicts with What is Already Bound

  - by davemackey

  I'm running Microsoft LightSwitch Beta 1 and have been creating an application which has been going great, but then I tried debugging after making a few minor changes and received the following error: "Could not load file or assembly 'SW_Resources.Commom, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The requested assembly version conflicts with what is already bound in the app domain or specified in the manifest. (Exception from HRESULT: 0x80131053)" I've tried emptying my cache in Firefox and IE but that doesn't seem to make any difference. I did discover if I right-clicked on the Solution and changed the version from 0.1 to 1.0 then it works fine. I had changed it to 0.1 b/c I wanted to reflect that it wasn't a release version...any thoughts on how to get around this issue the right way?

• what is the exact difference between PHP static class and singleton class

  - by Saif Bechan

  I have always used a Singleton class for a registry object in PHP. As all Singleton classes I think the main method looks like this: class registry { public static function singleton() { if( !isset( self::$instance ) ) { self::$instance = new registry(); } return self::$instance; } public function doSomething() { echo 'something'; } } So whenever I need something of the registry class I use a function like this: registry::singleton()->doSomethine(); Now I do not understand what the difference is between creating just a normal static function. Will it create a new object if I just use a normal static class. class registry { public static function doSomething() { echo 'something'; } } Now I can just use: registry::doSomethine(); Can someone explain to me what the function is of the singleton class. I really do not understand this.

• Running ASP.NET MVC application behind a proxy with different root relative path

  - by Wiebe

  Hi All, I'm having trouble with paths in a ASP.NET MVC application that's running behind a proxy. Our IIS Application root path is for example http://server/MyApp/ meaning that all urls using the application root ("~/",Url.Action("MyAction","MyController")) are resolved to "/MyApp" Now we're running behind a proxy server that forwards all requests, but changes the application root to something like this: "/Secury/Proxy/RubbishUrl/MyApp" Because the original url is only available on the client, I thought of creating a cookie with the path prefix, and insert this before each generated URL on the server. Now the question is, what's the best location in code to modify each URL that's resolved/sent to the client (to resources, controller actions, images etc)? Every path in the application is resolved with the MVC methods (Url.Content, Url.Action etc).

• Passing Reference types by value in C#

  - by Ajit

  I want to pass a reference type by value to a method in C#. Is there a way to do it. In C++, I could always rely on the copy constructor to come into play if I wanted to pass by Value. Is there any way in C# except: 1. Explicitly creating a new object 2. Implementing IClonable and then calling Clone method. Here's a small example: Let's take a class A in C++ which implements a copy constructor. A method func1(Class a), I can call it by saying func1(objA) (Automatically creates a copy) Does anything similar exist in C#. By the way, I'm using Visual Studio 2005.

• Inject same DataContext instance across several types with Unity

  - by Sergejus

  Suppose I have IRepository interface and its implementation SqlRepository that takes as an argument LINQ to SQL DataContext. Suppose as well that I have IService interface and its implementation Services that takes three IRepository, IRepository and IRepository. Demo code is below: public interface IRepository<T> { } public class SqlRepository<T> : IRepository<T> { public SqlRepository(DataContext dc) { ... } } public interface IService<T> { } public class Service<T,T1,T2,T3> : IService<T> { public Service(IRepository<T1> r1, IRepository<T2>, IRepository<T3>) { ... } } Is it any way while creating Service class to inject all three repositories with the same DataContext?

• Safari's never-ending loading message when an iframe does not have a src

  - by Matthew Pennell

  I'm using @rem's jQuery :visited plugin to do something with visited links on a page. The plugin works by creating an invisible iframe, injecting the HTML source, and comparing the colour of links to see which have been visited. It works perfectly. The problem I have is that on Safari, the status bar message always hangs on "Loading (X-1) of X items" - i.e. it thinks there is still some resource still needing to be loaded. I've narrowed it down to this plugin, and the fact that it attaches the IFRAME element to the BODY before the src is set (or injected in this case). I've tried rearranging the code to set the src before the append happens, but that breaks the plugin's functionality. Anyone have any ideas how to fix this issue? It's not a major issue as the site still functions perfectly well, but it's an annoying glitch that could be confusing to users.

• Design issue with ATG CommercePipelineManager

  - by user1339772

  The definition of runProcess() method in PipelineManager is public PipelineResult runProcess(String pChainId, Object pParam) throws RunProcessException This gives me an impression that ANY object can be passed as the second param. However, ATG OOTB has PipelineManager component referring to CommercePipelineManager class which overrides the runProcess() method and downcast pParam to map and adds siteId to it. Basically, this enforces the client code to send only Map. Thus, if one needs to create a new pipeline chain, has to use map as data structure to pass on the data. Offcourse, one can always get around this by creating a new PipelineManager component, but I was just wondering the thought behind explicitly using map in CommercePipelineManager

• Working with OAuth on Google with Python

  - by Dan Loewenherz

  I'm having a very frustrating time creating a valid signature for Google's OAuth implementation. I have narrowed it all down to the fact that my signature-generation code has an error of some sort; what it is I have no idea. This is the signature base string in its entirety: GET&https%3A%2F%2Fwww.google.com%2Faccounts%2FOAuthGetAccessToken&oauth_consumer_key%3Ddlosplayground.appspot.com%26oauth_nonce%3D72815d55697cb24301fab03e1f7f1d66%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1274327867%26oauth_token%3D4%252FX2cZ54JuseQbgRwzTBzZ7lqIwqof%26oauth_verifier%3Dihf0F2Fx%252FpnCmwbVQnk2xMre%26oauth_version%3D1.0 The OAuth Playground returns an oauth_signature of gF8qAfWjpdKjKb4KR%2FvA2Gy0vhU%3D. My code gives me ikMpIKJQJ58jseg%2BKPBTecjmYPE%3D, so obviously I'm doing something wrong. Here's my signature generation code (equivalent to that of the standard oauth.py library): binascii.b2a_base64(hmac.new(CONSUMER_SECRET, BASE_STRING, hashlib.sha1).digest())[:-1] Any thoughts?

• iSightAudio.plugin error when playing video using MediaPlayer

  - by Elisabeth

  I am working on creating a simple iPhone app that plays a movie via URL. When I Build&Run to test in the simulator, it works fine; as soon as I start playing the movie, I get the following message in the console: [1757:4b03] Cannot find executable for CFBundle/CFPlugIn 0x820ffe0 </Library/Audio/Plug-Ins/HAL/iSightAudio.plugin> (not loaded) [1757:4b03] Cannot find function pointer iSightAudioNewPlugIn for factory 9BE7661E-8AEF-11D7-8692-000A959F49B0 in CFBundle/CFPlugIn 0x820ffe0 </Library/Audio/Plug-Ins/HAL/iSightAudio.plugin> (not loaded) I don't get this error on other programs, so I assume it has something to do with this specific program, which uses the MediaPlayer.framework. Does anyone know what is causing this problem and how to fix it? Thank you

• Upgrading website from VS2005(2.0 Framework) to VS2008(2.0 Framework)

  - by Sravan

  We have a website that is created in VS2005 Recently we upgraded the website to VS2008 with 2.0 framework. While compiling the website Compilation errors are occuring i.e Licenses.licx file is not compiling, if it compile than it will reproduces an AppLicenses.dll. In the licensing.licx file containing one class and a namespace(i.e. OSADirectLicensing.OSADirectLicensedClass, OSADirectLicensing). The compilation error is as follows: Error 1 C:\Program Files\Sharp\Sharp Developer Tools\OSA SDK\Samples\DirectOSA\ExternalAuthority\licenses.licx: Could not transform licenses file into a binary resource.
