• What alternatives are there for asp.net forms authentication?

  - by Eytan Levit

  Hi, We are developing a web app that will have a pretty complex user and permission system. The general idea is that we have 3 levels of security: a simple user - that can only access basic data that is in a data repository a manager - that can open up data repositories a superuser - that can open up repository factories. each repository contains various data types(text, images, etc etc). We are looking for authentication methods that will allow us: 1. Scalability. 2. Customization. 3. To create permissions that will effect the GUI + deny access to certain pages. 4. To create predefined roles - that will allow for easy setup of new users. 5. To create custom roles for specific users - allowing them permission sets that are different from the predefined roles. Thanks in advance

• Cannot customize Solution Explorer project context menu in VS 2010

  - by mikoro

  I'm trying to customize that context menu which comes up when you right click the project in the Solution Explorer. When I goto: Tools - Customize - Commands - Context Menu (radio button) - Project and Solution Context Menus | Project (drop down) I get nothing in the "controls:" list. I can modify other context menus starting with "Project and Solution Context Menus" but none of them is the right one. Any ideas? Currently I have ReSharper, PowerTools and StyleCop installed, but I have installed and uninstalled bunch of other addins (dotTrace, CodeIt.Right, VisualHG, DevExpress, random stuff from Extension Manager).

• MongoDB or CouchDB - fit for production?

  - by Alan

  I was wondering if anyone can tell me if MongoDB or CouchDB are ready for a production environment. I'm now looking at these storage solutions (I'm favouring MongoDB at the moment), however these projects are quite young and so I foresee that I'm going to have to work quite hard to convince my manager that we should adopt this new technology. What I'd like to know is: 1) Who is using MongoDB or CouchDB today in a production environment? 2) How are you using MongoDB/CouchDB? 3) What problems (if any) did you come across when you adopted this new storage mechanism (and how did you overcome them)? 4) How did you deal with any migration issues that you had to deal with? 5) Do you have any good/bad experiences with either of these solutions that you'd like to share? Thanks.

• Is it good to commit files often if using Mercurial or Git?

  - by Jian Lin

  It seems that it is suggested we can commit often to keep track of intermediate changes of code we wrote… such as on hginit.com, when using Mercurial or Git. However, let's say if we work on a project, and we commit files often. Now for one reason or another, the manager wants part of the feature to go out, so we need to do a push, but I heard that on Mercurial or Git, there is no way to push individual files or a folder… either everything committed gets pushed or nothing get pushed. So we either have to revert all those files we don't want to push, or we just never should commit until before we push -- right after commit, we push?

• How to install older Android SDK in Eclipse

  - by John Brunner

  I'm working at the moment at a simple app in eclipse for android. Just receiving and sending data, and using the camera API. I've set the minSDKversion to 8, because I think that has the widest user base. But at the beginning of the project eclipse was asking me which target SDK version I would use, and because I had just one installed (the latest 4.0.3) I've took this. Now I'm asking me if it wouldn't be wiser to install a lower SDK, like Android 2.2, because it would be not that big (compared to the 4.0.3) and my app would not have included all the fancy new features, which are not used in any way?! Or is this complete nonsense I'm talking here, and just should take my 4.0.3 SDK? When not, how can I install a lower version? Help -> SDK Manager is not showing old SDKs...

• Using LocationManager from another class than Main

  - by iphonePom

  Hi, i'm new here, i'm new in iphone development, i'm new in Objective-c and i'm new in engligh speaking, so don't hate me :P I'm creating an application that will use the location manager to display the distance between the own position and the positions of a list of shops, like AroundME. Now, i give the locationManager property to my main class and in the .m of that class, precisely in the viewDidLoad method, i make: [locationManager startUpdatingLocation]. It all works fine, but the problem is: i need to know my position in other classes than the main, but i don't think that is a good idea making [locationManager startUpdatingLocation] every time i need it, is not time overhead? The view of my main class is always below the others, so can i retrieve the updated location in my other classes? In what way? Creating another instance of my main class is not useful, i think, but the locationManager, once started, doesn't stop until my main class is released, isn't true? So i think that it is accessible in some way. Thanks for your attention and sorry for my awful english : )

• Branch for each developer in GIT repo

  - by Peter

  I'd like to move my project to GitHub from local svn repository. Multiple developers are curently working on this project. I was thinking that each developer should have their own branch in which they would commit changes. When manager review their work, he will merge it into master branch. I don't want separate repository for each developer as GitHub has limited number of private repositories. Is this a good idea? What are other alternatives?

• django - order query set by postgres function

  - by thebiglife

  My initial question was here and was related to the postgres backend. http://stackoverflow.com/questions/2408965/postgres-subquery-ordering-by-subquery Now my problem has moved onwards to the Django ORM layer. I essentially want to order a query by a postgres function ('idx', taken from the above stackoverflow work) I've gone through trying to use model.objects.extra(order_by ) or simply order_by but I believe both of these need the order_by parameter to be an attribute or a field known to Django. I'm trying to think how to solve this without having to revert to using an entirely raw SQL query through a model manager.

• I need to debug my BrowserHelperObject (BHO) (in C++) after a internet explorer 8 crash in Release m

  - by BHOdevelopper

  Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

• Agile version control?

  - by Paul Dixon

  I'm trying to work out a good method to manage code changes on a large project with multiple teams. We use subversion at the moment, but I want more flexibility in building a new release than I seem to be able to get with subversion. Here's roughly I want: for each developer to create easily identifiable patches for the project. Each patch delivers a complete user story (a releasable feature or fix). It might encompass many changes to many files. developers are able to easily apply and remove their own and other patches to facilitate testing release manager selects the patches to be used in the next release into a new branch branch is tested, fixes merged in, and ultimately merged into live teams can then pull these changes back down into their sandboxes. I'm looking at stacked git as a way of achieving this, but what other tools or techniques can deliver this sort of workflow?

• Execute a dll function in ASP.Net Bin not working, II7.

  - by Wayne Lo

  I am developing a remote control application where a client (aspx page in a browser) can request a server to "launch a notepad" (for testing purpose, for real life, turning off a light bulb, etc). So I created a dll with a simple function for launching the notepad (on the server side) and dropped this dll in the root bin folder. It worked fine when the aspx page is running under ASP.NET development server (launched from Visual Studio). But when I tested the same aspx page under a FireFox browser, it did not work (launch the notepad) even though it did call for the same function (I stepped through in debugger). Is this a permission issue? How do I set this up in IIS manager, or even better in web.config? Please help.

• Trying to modify a constraint in PostgresSQL

  - by MISMajorDeveloperAnyways

  Postgres is getting quite annoying lately. I have checked the documentation provided by Oracle and found a way to do this without dropping the table. Problem is, it errors out at modify as it does not recognize the keyword. Using EMS SQL Manager for PostgreSQL. Alter table public.public_insurer_credit MODIFY CONSTRAINT public_insurer_credit_fk1 deferrable, initially deferred; I was able to work around it by dropping the constraint using : ALTER TABLE "public"."public_insurer_credit" DROP CONSTRAINT "public_insurer_credit_fk1" RESTRICT; ALTER TABLE "public"."public_insurer_credit" ADD CONSTRAINT "public_insurer_credit_fk1" FOREIGN KEY ("branch_id", "order_id", "public_insurer_id") REFERENCES "public"."order_public_insurer"("branch_id", "order_id", "public_insurer_id") ON UPDATE CASCADE ON DELETE NO ACTION DEFERRABLE INITIALLY DEFERRED;

• Problem with running a program from flashdrive

  - by rajivpradeep

  I have a USB drive with two partitions in it, one hidden and one normal. I have an application which swaps the memory and runs the flash application in hidden zone. The problem is that the application works fine on Windows 7 and when run on Win XP, it swaps the partitions but doesn't run the flash applications but just keeps running in the background. I can see it in task manager. But, when I copy the application to desktop and run, it runs with no glitch. I was facing the same problem on Win 7 too, but it was running as required when I ran it using "Run in XP mode" and then I applied a SHIM and is running since then as required. The application is built using VC++ 2008. does anyone know the solution?

• Application.Idle causes high CPU usage

  - by Neal

  Hello, I use the Application.Idle event to handle toolbar status (enable/disable) etc. quite extensively. As I'm beta testing Norton AntiVirus 2011, it brought to my attention that my app that I'm developing triggered a high CPU usage warning on at least one CPU. Sure enough, I opened the task manager and watched one of the four CPU's (quad core system) go to near 100%. I thought Application.Idle was the way to handle things when the application wasn't performing CPU tasks. Why is Application.Idle spiking the CPU? Here is how I attach to the event: AddHandler Application.Idle, AddressOf OnAppIdle Been using Application.Idle for a long time, never knew it would have this issue. Using VS 2010 .NET 4 Thank you.

• SQLBindParameter is working fine but SQLExecute gives error in Windows 2008 Server 64bit.

  - by rajugkgp

  Dear All, I am migrating my application from 32bit(Windows 2003 Server) to 64bit (Windows 2008 Server R2).I am getting the following while trying to execute a SQL command Encountered ODBC error -1: S1010, 0, [Microsoft][ODBC Driver Manager] Function sequence error . Basically internal function call is SQLExecute() function call. This works perfectly for Windows 2003 Server 32bit. I tried the command execute at the background from the command prompt and it is working. Any help or suggestion would be very much appreciated. I checked the squence of call.We have two consecutive SQLBindParameter function call and then we call SQLExecute. Is this sequence incorrect in case of 64bit? I also checked the return code given by SQLExecute which is 99. Any pointers or suggestions would be very helpful. The above sequence is working fine with 32bit Windows. Thanks in advance. -R

• SSIS web service task producing "object reference" error

  - by gfrizzle

  Our care management system uses a web service to import data. I've successfully executed one of its methods using soapUI, and now I want to replicate this with an SSIS 2008 web service task, but I'm running into a problem. I've created the "HTTP Connection Manager" successfully, and specified the location of the "WSDLFile", but when I go to the Input tab and select the Service from the dropdown (there is only one), I get an "Object reference not set to an instance of an object" error, and and the Method dropdown is empty. Any idea what this is trying to tell me?

• PHP Doctrine 1.2 table names

  - by Ofir

  I'm trying to upgrade my doctrine ORM from 1.1.6 to 1.2.1 but i've enountered a BC issue with table names. Some of my table names have several words (e.g. t_foo_bar for class FooBar) where the t_ prefix is generated automatically with: $manager->setAttribute(Doctrine_Core::ATTR_TBLNAME_FORMAT, 't_%s'); This worked well in previous versions. In 1.2.1 however, it looks like doctrine is looking for t_foobar (instead of t_foo_bar with an underscore). Do you know how to solve this without changing the table names?

• Where is the chink in Google Chrome's armor?

  - by kudlur

  While browsing with Chrome, I noticed that it responds extremely fast (in comparison with IE and Firefox on my laptop) in terms of rendering pages, including JavaScript heavy sites like gmail. This is what googlebook on Chrome has to say tabs are hosted in process rather than thread. compile javascript using V8 engine as opposed to interpreting. Introduce new virtual machine to support javascript heavy apps introduce "hidden class transitions" and apply dynamic optimization to speed up things. Replace inefficient "Conservative garbage colllection" scheme with more precise garbage collection scheme. Introduce their own task scheduler and memory manager to manage the browser environment. All this sounds so familiar, and Microsoft has been doing such things for long time.. Windows os, C++, C# etc compilers, CLR, and so on. So why isn't Microsoft or any other browser vendor taking Chrome's approach? Is there a flaw in Chrome's approach? If not, is the rest of browser vendor community caught unaware with Google's approach?

• Tomcat application: Frequent OutOfMemory PermGen exception while image uploads

  - by rabbit

  Hi, I have a tomcat 6 application which I have set parameters of -Xms512m -Xmx1024m. I thought 1 GB of memory in a 4 GB RAM would be enough, but that is not the case. On application stop/start multiple times (from tomcat manager) and also on image uploads (sometimes) I run into the OutOfMemory PermGen space error and the site stops responding. Should I increase the memory still some more? Is there anything else that I can do to from the tomcat side so that it does not run into the PermGen space issue? Thanks in advance for pointers/tips etc.

• Should a service layer return view models for an MVC application?

  - by erg39

  Say you have an ASP.NET MVC project and are using a service layer, such as in this contact manager tutorial on the asp.net site: http://www.asp.net/mvc/tutorials/iteration-4-make-the-application-loosely-coupled-cs If you have viewmodels for your views, is the service layer the appropriate place to provide each viewmodel? For instance, in the service layer code sample there is a method public IEnumerable<Contact> ListContacts() { return _repository.ListContacts(); } If instead you wanted a IEnumerable, should it go in the service layer, or is there somewhere else that is the "correct" place? Perhaps more appropriately, if you have a separate viewmodel for each view associated with ContactController, should ContactManagerService have a separate method to return each viewmodel?

• WSAT Security tab error for Custom Role provider

  - by shesb

  I have created custome Membership Role and Profile provider using INGRES db. Now I can see my IngresMembership and IngresRole provider in the Provider tab(Select a different provider for each feature (advanced) ) of WSAT but when I clik on security tab I get this error: "There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: Object reference not set to an instance of an object." What am I missing? Do I need to add code for all override methods for Role provider? I have just written code for the Initialize and GetRolesForUser functions. Thanks

• Set existing Web Service Extension to "Allow" using WiX

  - by Friend Of George

  In IIS Manager under Web Service Extensions, ASP.NET v2.0.50727 is set to "Prohibited" by default. I would like to set this to Allow during the install. I am currently using WiX Version 2. I have tried using: <Component Id="Allow_WebServiceExtension_ASP.NET_2.0" DiskId="1" Guid="02247363-E423-41E1-AC15-BEF589B65A4D"> <WebServiceExtension Id="WebServiceExtension_ASP.NET_2.0" Allow="yes" File="%SystemRoot%\Microsoft.NET\Framework\[DOTNETFRAMEWORKVER]\aspnet_isapi.dll" Description="ASP.NET v2.0.50727" UIDeletable="no" /> </Component> This adds a second ASP.NET 2.0.50727 entry and does not enable the first.

• How do I test switching compilers from MSVS 6 to MSVS 2008?

  - by Leif

  When switching from MSVS 6 to MSVS 2008, what major differences should I look for when testing the software? I'm coming from more of a QA perspective. We have two programs that work closely together that were originally compiled in Visual C++ 6. Now one of the programs has been compiled in Visual C++ 2008 in order to use a specific CD writing routine. The other program is still compiled under MSVS 6. My manager is very concerned with this change and wants me to run tests specific to this change. Since I deal more with QA and less with development, I really have no idea where to start. I've looked for differences between the two, but nothing has given me a clear direction as far as testing is concerned. Any suggestions would be helpful.
