  • IIS5 to IIS6 upgrade, and the bin folder

    - by NickLarsen
    We had a website running under IIS5 which used the bin directory as a housing for some asp pages as well as files for download and after upgrading to IIS6, we only get a 404 error when trying to access anything in that folder. We do not store any sensitive information in there, or code, and it would require a major overhaul of not only our system, but our clients' systems as well. Is there some configuration setting we are overlooking or is it just that IIS6 will no longer let you use the bin folder as just another directory?

  • How much abstraction is too much?

    - by Daniel Bingham
    In an Object Oriented Program: How much abstraction is too much? How much is just right? I have always been a nuts and bolts kind of guy. I understood the concept behind high levels of encapsulation and abstraction, but always felt instinctively that adding too much would just confuse the program. I always tried to shoot for an amount of abstraction that left no empty classes or layers. And where in doubt, instead of adding a new layer to the hierarchy, I would try and fit something into the existing layers. However, recently I've been encountering more highly abstracted systems. Systems where everything that could require a representation later in the hierarchy gets one up front. This leads to a lot of empty layers, which at first seems like bad design. However, on second thought I've come to realize that leaving those empty layers gives you more places to hook into in the future with out much refactoring. It leaves you greater ability to add new functionality on top of the old with out doing nearly as much work to adjust the old. The two risks of this seem to be that you could get the layers you need wrong. In this case one would wind up still needing to do substantial refactoring to extend the code and would still have a ton of never used layers. But depending on how much time you spend coming up with the initial abstractions, the chance of screwing it up, and the time that could be saved later if you get it right - it may still be worth it to try. The other risk I can think of is the risk of over doing it and never needing all the extra layers. But is that really so bad? Are extra class layers really so expensive that it is much of a loss if they are never used? The biggest expense and loss here would be time that is lost up front coming up with the layers. But much of that time still might be saved later when one can work with the abstracted code rather than more low level code. So when is it too much? At what point do the empty layers and extra "might need" abstractions become overkill? How little is too little? Where's the sweet spot? Are there any dependable rules of thumb you've found in the course of your career that help you judge the amount of abstraction needed?

  • Free SCM for Matlab 64 bit version on Windows

    - by Asaf R
    When Matlab is installed in its 64 bit version, it can use only 64 bit source control systems. Is there a source control system that's free, works with 64 bit Matlab and runs on Windows? It can be a system that supports only one developer. It can be 32 bit itself, if it'll work. It will be installed on the same machine as the Matlab in use, which is a Win7 Ultimate x64 machine.

  • Still getting duplicate token error after calling DuplicateTokenEx for impersonated token

    - by atconway
    I'm trying to return a Sytem.IntPtr from a service call so that the client can use impersonation to call some code. My imersonation code works properly if not passing the token back from a WCF service. I'm not sure why this is not working. I get the following error: "Invalid token for impersonation - it cannot be duplicated." Here is my code that does work except when I try to pass the token back from a service to a WinForm C# client to then impersonate. [DllImport("advapi32.dll", EntryPoint = "DuplicateTokenEx")] public extern static bool DuplicateTokenEx(IntPtr ExistingTokenHandle, uint dwDesiredAccess, ref SECURITY_ATTRIBUTES lpThreadAttributes, int TokenType, int ImpersonationLevel, ref IntPtr DuplicateTokenHandle); private IntPtr tokenHandle = new IntPtr(0); private IntPtr dupeTokenHandle = new IntPtr(0); [StructLayout(LayoutKind.Sequential)] public struct SECURITY_ATTRIBUTES { public int Length; public IntPtr lpSecurityDescriptor; public bool bInheritHandle; } public enum SecurityImpersonationLevel { SecurityAnonymous = 0, SecurityIdentification = 1, SecurityImpersonation = 2, SecurityDelegation = 3 } public enum TokenType { TokenPrimary = 1, TokenImpersonation = 2 } private const int MAXIMUM_ALLOWED = 0x2000000; [PermissionSetAttribute(SecurityAction.Demand, Name = "FullTrust")] public System.IntPtr GetWindowsUserToken(string UserName, string Password, string DomainName) { IntPtr tokenHandle = new IntPtr(0); IntPtr dupTokenHandle = new IntPtr(0); const int LOGON32_PROVIDER_DEFAULT = 0; //This parameter causes LogonUser to create a primary token. const int LOGON32_LOGON_INTERACTIVE = 2; //Initialize the token handle tokenHandle = IntPtr.Zero; //Call LogonUser to obtain a handle to an access token for credentials supplied. bool returnValue = LogonUser(UserName, DomainName, Password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref tokenHandle); //Make sure a token was returned; if no populate the ResultCode and throw an exception: int ResultCode = 0; if (false == returnValue) { ResultCode = Marshal.GetLastWin32Error(); throw new System.ComponentModel.Win32Exception(ResultCode, "API call to LogonUser failed with error code : " + ResultCode); } SECURITY_ATTRIBUTES sa = new SECURITY_ATTRIBUTES(); sa.bInheritHandle = true; sa.Length = Marshal.SizeOf(sa); sa.lpSecurityDescriptor = (IntPtr)0; bool dupReturnValue = DuplicateTokenEx(tokenHandle, MAXIMUM_ALLOWED, ref sa, (int)SecurityImpersonationLevel.SecurityDelegation, (int)TokenType.TokenImpersonation, ref dupTokenHandle); int ResultCodeDup = 0; if (false == dupReturnValue) { ResultCodeDup = Marshal.GetLastWin32Error(); throw new System.ComponentModel.Win32Exception(ResultCode, "API call to DuplicateToken failed with error code : " + ResultCode); } //Return the user token return dupTokenHandle; } Any idea if I'm not using the call to DuplicateTokenEx correctly? According to the MSDN documentation I read here I should be able to create a token valid for delegation and use across the context on remote systems. When 'SecurityDelegation' is used, the server process can impersonate the client's security context on remote systems. Thanks!

  • Asp.net MVC and MOSS 2010 integration

    - by Robert Koritnik
    Just a sidenote: I'm not sure whether I should post this to serverfault as well, because some MOSS admin may have some info for me as well? A bit of explanation first (without Asp.net MVC) Is it possible to integrate the two? Is it possible to write an application that would share at least credential information with MOSS? I have to write a MOSS application that has to do with these technologies: MOSS 2010 Personal client certificates authentication (most probably on USB keys) Active Directory Federation Services Separate SQL DB that would serve application specific data (separate as not being part of MOSS DB) How should it work? Users should authenticate using personal certificates into MOSS 2010 There would be a certain part of MOSS that would be related to my custom application This application should only authorize certain users via AD FS - I guess these users should have a certain security claim attached to them This application should manage users (that have access to this app) with additional (app specific) security claims related to this application (as additional application level authorization rights for individual application parts) This application should use custom SQL 2008 DB heavily with its own data This application should have the possibility to integrate with external systems as well (Exchange for instance to inject calendar entries, ERP systems etc) This application should be able to export its data (from its DB) to files. I don't know if it's possible, but it would be nice if the app could add these files to MOSS and attach authorization info to them so only users with sufficient rights would be able to view/open these files. Why Asp.net MVC then? I'm very well versed in Asp.net MVC (also with the latest version) and I haven't done anything on Sharepoint since version 2003 (which doesn't do me no good or prepare me for the latest version in any way shape or form). This project will most probably be a death march project so I would rather write my application as a UI rich Asp.net MVC application and somehow integrate it into MOSS. But not only via a link, because I would like to at least share credentials, so users wouldn't need to re-login when accessing my app. Using Asp.net MVC I would at least have the possibility to finish on time or be less death marching. Is this at all possible? Questions Is it possible to integrate Asp.net MVC into MOSS as described above? If integration is not possible, would it be possible to create a completely MOSS based application that would work as described? Which parts of MOSS 2010 should I use to accomplish what I need?

  • Camel-like integration component for Ruby

    - by Matthias Hryniszak
    Hi, I'm in need to get some integration work done in my ruby application. My main focus is web services and ActiveMQ integration (the systems I'm going to connect to are mainly written in Java). I was wondering if there's something that resembles the capabilities of Camel in Ruby? All I need is something that'll let me define routing between incoming data from those sources I mentioned above, do some pre-processing and post them back somewhere else. Thanks, Matthias

  • What development technologies or technology stack is typically used in the security industry?

    - by vfilby
    In this case security means building security (access control, alarm systems, etc). And I am not talking about working directly with the hardware, more focused on web based applications/api's that clients or companies can use? Are there technologies that are commonly used? Are there technologies that shouldn't be used? Are there any real benefits to a linux based stack as opposed to a windows based stack for exposing web based applications?

  • What are some viable alternatives to BizTalk Server?

    - by Kilhoffer
    In evaluating different systems integration strategies, I've come across some words of encouragement, but also some words of frustration over BizTalk Server. What are some pros and cons to using BizTalk Server (both from a developer standpoint and a business user), and should companies also consider open source alternatives? What viable alternatives are out there? EDIT: Jitterbit seems like an interesting choice. Open Source and seems to be nicely engineered. Anyone on here have any experience working with it?

  • Good tools for using Git on windows

    - by Ali Shafai
    I've been using SVN for my projects and had visualSVN for VS integration. however the Git work flow is different from traditional source control systems (Checkout/edit/stage/commit as oppose to Checkout/edit/commit). I was wondering if there is a good VS addon to support that. Also any good advice on using git on a windows dev machine is appreciated.

  • Lightweight PHP5 based template class/system

    - by Wizzard
    Hi there. Looking at using a template system for a new project, it's only a small site and don't want to use the overhead and 'complexity' of smarty. I don't really like template systems that force you to make use of another language just to make it easier for designers (apparently). Something like this http://www.namepros.com/code/517342-php5-template-class.html is what Im looking at but something which is a bit more robust and proven.
