  • ASP.NET MVC authorization & permission to use model classes

    - by Tomek
    Hi, This is my first post here, so hello :) Okey, let's get to the point... I am writing my first app in ASP.NET MVC Framework and i have a problem with checking privileges to use instances of model classes (read, edit). Sample code looks like this: // Controller action [CustomAuthorize(Roles="Editor, Admin")] public ActionResult Stats(int id) { User user = userRepository.GetUser(id); if (user == null || !user.Activated || user.Removed) return View("NotFound"); else if (!user.IsCurrentSessionUserOwned) return View("NotAuthorized"); return View(user); } So far authorize attribute protects only controller actions, so my question is: how to make (custom) authorize attribute to check not only user role, usernames but also did i.e. resources instantiated in action methods (above: User class, but there are other ORM objects like News, Photos etc.) All of these object to check have their unique ID's, so user have own ID, News have their ID and UserID field referecned to Users table (i mean these objects are LINQ2SQL classes). How should i resolve that problem?

  • How do I move a Java JFrame partially off my Linux desktop?

    - by Erick Robertson
    I'm writing a Java application with movable frames, and I've come across a quirk in Linux. I'm running GNOME 2.16.0 under CentOS. When I use JFrame.setBounds to set the bounds to any location that's half off the screen, it actually sets the location of the frame to be as close as possible to the bounds specified while still staying completely on the screen. This is confusing because other non-Java windows can move half off the screen. How do I tell Java to tell GNOME to actually put the frame where I specify, even if that's half off the screen?

  • How do I wait for a service/process to start before continuing a batch script?

    - by Shane McD
    I am writing a windows batch script to uninstall some software. However I need to wait after the uninstaller has finished for a service to be restarted before continuing with the next uninstall. I can make the script wait for the uninstaller to finsh using:- for /f "usebackq" %%M in ('tasklist /nh /fi "imagename eq %process_1%"') do if not %%M==%ignore_result% goto 1 But I cannot for the life of me figure out how to get the script to then wait for a service to start before continuing the script and running more uninstalls. I am open to any suggestions.

  • UTF-8 BOM in php response to mootools xmlhttprequest

    - by Jimmy
    Hi, I'm writing my first little AJAX-enabled Joomla component. I'm using mootools. I got a xmlhttprequest to contact my Joomla component, and the component returns a response - just plain text echoed by php, like echo 'Hello World!'; It's all working fine, except wireshark tells me that the response is prepended with \357\273\277\357\273\277 when it gets read by the javascript on the client side. This shows up as a little square before the response in an alert box that the script shows. I don't explicitly set the encoding on the xmlhttprequest; mootools docs say that it defaults to UTF8. What's the right way to handle this? Should I be setting the encoding on the request? Mime type? Should the javascript get rid of it? I'm not planning to have any characters requiring UTF8 in the response, so using plain old ascii would be ok for me too. Thanks

  • Proper way to set object instance variables

    - by ensnare
    I'm writing a class to insert users into a database, and before I get too far in, I just want to make sure that my OO approach is clean: class User(object): def setName(self,name): #Do sanity checks on name self._name = name def setPassword(self,password): #Check password length > 6 characters #Encrypt to md5 self._password = password def commit(self): #Commit to database >>u = User() >>u.setName('Jason Martinez') >>u.setPassword('linebreak') >>u.commit() Is this the right approach? Should I declare class variables up top? Should I use a _ in front of all the class variables to make them private? Thanks for helping out.

  • CREATE mysql database with default InnoDB tables?

    - by memilanuk
    Hello, I've been working on writing a SQL statement to create a MySQL database with several default options, including default character set and default collate. Is it possible to add syntax to make the default engine type for tables in this database to be innodb? I've been looking through the MySQL manual for v.5.1 and I've found the statement 'ENGINE=innodb' which would be appended to a CREATE TABLE statement... but I haven't found anything related to a CREATE DATABASE statement. Is there a normal way to do this as part of the database creation, or does it need to be specified on a table-by-table basis? Thanks, Monte

  • Matlab tutorial for programmers

    - by Jonas
    I'm getting some new students soon, who will be writing Matlab code. They're new to Matlab, but they have experience coding in Java and C++. I'm going to have them go through the 'Getting Started' section of the Matlab help. In addition, I want to give a small tutorial with the goal to prevent them from making some of the most common mistakes people make when switching to Matlab ("Matlab starts counting at 1"), and show them some features that they may not be aware of when coming from other languages ("you can subtract a scalar directly from an array, and for vectors, there's bsxfun"). What are the most important things I should tell them?

  • Test problem using JUnitPerf

    - by allenzzzxd
    Hi, guys, I'm writing a JUnit test using JUnitPerf. Here, I want to generate some entries and use them to update a database. To test the capacity of the database, I want several test to run simultaneously or randomly, so I use, for example: Test loadTest = new LoadTest(testCase, n); But, still, I have to insure that in each test, a different update source will be used so that a different entry in the database will be updated. So my question is how can I realize this? Thanks a lot Allen

  • Air XmlHttpRequest time out if remote server is offline?

    - by Seth
    I'm writing an AIR application that communicates with a server via XmlHttpRequest. The problem that I'm having is that if the server is unreachable, my asynchronous XmlHttpRequest never seems to fail. My onreadystatechange handler detects the OPENED state, but nothing else. Is there a way to make the XmlHttpRequest time out? Do I have to do something silly like using setTimeout() to wait a while then abort() if the connection isn't established? Edit: Found this, but in my testing, wrapping my xmlhttprequest.send() in a try/catch block or setting a value on xmlhttprequest.timeout (or TimeOut or timeOut) doesn't have any affect.

  • Reading Excel spreadsheets with Delphi

    - by Bruce McGee
    I need to read from and write to Excel spreadsheets using Delphi 2010. Nothing fancy. Just reading and writing values from specific cells and ranges on different sheets. Needs to work without having Excel installed and support Excel 2007. Some things I've looked at: I've tried using ADO, which works OK for selecting everything in an entire sheet, but I haven't had much luck reading specific cells or ranges. NativeExcel looked promising, but it doesn't seem to be in active development, and they don't respond to e-mails. Axolot has a couple of products. The main product seems to be very functional, but is pricey. They have a lite version, but it doesn't support Delphi 2010. Any recommendations? Free would be great, but I'm open to a commercial solution as long as it's reliable and well supported.

  • Data structure in c for fast look-up/insertion/removal of integers (from a known finite domain)

    - by MrDatabase
    I'm writing a mobile phone based game in c. I'm interested in a data structure that supports fast (amortized O(1) if possible) insertion, look-up, and removal. The data structure will store integers from the domain [0, n] where n is known ahead of time (it's a constant) and n is relatively small (on the order of 100000). So far I've considered an array of integers where the "ith" bit is set iff the "ith" integer is contained in the set (so a[0] is integers 0 through 31, a[1] is integers 32 through 63 etc). Is there an easier way to do this in c?

  • UI Controls layer on top of operating system.

    - by Mason Blier
    I'm kind of curious about what layer writing a UI platform to the level of Win32 or the X Windowing System would fall in the grand scheme of an operating system. What layers below do they primarily make use of, is it heavily based on direct communication with the graphics card driver (I can't imagine going though a rendering pipeline like OpenGL for this), or is there a graphical platform as part of the operating system which extracts this out a little more. I'm also interested in the creation of shells and the like, and I"m particularly curious as to how people go about creating alternative shells for windows, what do people look for when figuring out what methods to call or what to hook into, etc? I guess I'm fairly lost at these concepts and finding it difficult to find documentation on them. I was initially excited to have taken Operating Systems in college but it was all low level resource management stuff. Thanks all, Mason

  • expected class,delegate,enum,interface or struct

    - by Luke
    Hello, I am writing a class. I have encountered the problem in the title. Here is the code: class delivery { private string strDeliveryName; private string strDeliveryAddress; private string strDeliveryDay; private string strDeliveryTime; private string strDeliveryMeal; private string strDeliveryInstructions; private string strDeliveryStatus; } public delivery(string deliveryName, string deliveryAddress, string deliveryDay, string deliveryTime, string deliveryMeal, string deliveryInstructions, string deliveryStatus) { strDeliveryName = deliveryName; strDeliveryAddress = deliveryAddress; strDeliveryDay = deliveryDay; strDeliveryTime = deliveryTime; strDeliveryMeal = deliveryMeal; strDeliveryInstructions = deliveryInstructions; strDeliveryStatus = deliveryStatus; } I get the error on the public delivery, any idea why?

  • questions about multi threading for sockets/tcp-connections.

    - by Fantastic Fourier
    I have a server that connects to multiple clients using TCP/IP connections, using C in Unix. Since it won't have more than 20 connections at a time, I figured I would use a thread per connection/socket. But the problem is writing to the sockets as I'll be sending user prompted msgs to clients. Once each socket is handled by a thread, how do I interact with the created thread to write to the sockets? Should each thread just read from the sockets and I'll write to sockets in the main program? Not sure if that's a good way to go about it.

  • Choosing http status code for unknown command reply

    - by w0rldart
    So, I'm writing a small test that I have been required to complete and I just want to give it some final touches by adding some header status code responses and some other stuff. Right now, my dilemma is what HTTP status code to choose for my "Unknown command" response after the $_GET['cmd'] has been compared to the existing commands list. case 404: $text = 'Not Found'; break; case 405: $text = 'Method Not Allowed'; break; case 406: $text = 'Not Acceptable'; break; For which one of the above should I go? And if none, which other?

  • How do I randomly fill an array in Java?

    - by Kat
    I'm writing a program that creates a 2D array from a integer n. I then have to fill the array with values from 1 to the n*n array size and check to see if it is a magic square. The way I am doing it now fills the array in order from 1 to n*n array size. How can I make that random? My code: System.out.print("Enter an whole number: "); int n = scan.nextInt(); int [][] magic = new int [n][n]; for (int row = 0; row < magic.length; row++) { for(int col = 0; col < magic[row].length; col++) magic[row][col] = ((row * n) + 1) + col; }

  • C# Reset a property

    - by Jeff
    I'm writing a Clone function for a non serializeable object.For most objects I don't care if they are shallow copied as I won't be making any changes to them. I start with a MemberwiseClone and this copies all the values and few objects like configuration dictionary over just fine but they are pointers. EAVEntity newClone = (EAVEntity) this.MemberwiseClone(); newClone.EntityStorageID = Guid.NewGuid(); newClone.Controls.Clear(); So how do I reset a pointer so I can make them not point at the same location?

  • How do i redirect to a GET request from a POST request on GAE

    - by user259349
    Hello everyone, i am writing an FBML app on facebook hosted in GAE. Facebook will talk to your hosted app only vai POST (im sure this is the cause, but please do correct me if i'm wrong). So im faced with the issue that inside of my POST method, i need to redirect to facebook OAuth authroize URL. But i can only send a GET request. How can i do that? At the moment i'm doing class OauthHandler(webapp.RequestHandler): def post(self): # blablablab request.redirect(oauth_uri) Which is wrong since the oauth_uri is only responding to GET. Further more, OAuth will redirect back to my redirect handler through GET, but i cant! i can only do post. So i'm confused. ideas? Thanks in advance

  • Does performance even matter anymore? [closed]

    - by Jeff Dahmer
    The performance differences between C/C++ and C# are astounding. An ASP.NET page loads in 1/8 the time that a PHP script does haha.... WPF, aka " The Future ", (you know it will be, all the companies are gonna want cool looking desktop apps, don't kid yourself.) And it has huge performance hits just to start up. We've let Microsoft make us as developers lazy! Why do I hate this, it's such a good thing? Are we at a point in time where the majority of computers can handle this kinda crap? I remember when performance used to matter. Anyways, I'm writing a .NET library and ever since I found out LINQ is slower than traditional delegates which is slower than the normal procedural code... well it's a guilty evil I feel for every LINQ query I write, because they are so beautiful. Am I just too much of a performance stickler? Or just too big of a nerd?

  • stumped by WSGI module import errors

    - by rguha
    Hi, I'm writing a bare bones Python wsgi application and am getting stumped by module import errors. I have a .py file in the current directory which initially failed to import. By adding sys.path.insert(0, '/Users/guhar/Sites/acom') the import of the module worked. But I now try and import a module that I had installed via easy_install and it fails to import. I tried setting sys.path.insert(0, '/Library/Python/2.5/site-packages/') which contains the egg file, but to no avail. I would've thought that all packages under "/Library/Python/2.5/site-packages/" would be available to a WSGI application. Does anybody have any pointers?

  • How can I temporarily redirect printf output to a c-string?

    - by Ben S
    I'm writing an assignment which involves adding some functionality to PostgreSQL on a Solaris box. As part of the assignment, we need to print some information on the client side (i.e.: using elog.) PostgreSQL already has lots of helper methods which print out the required information, however, the helper methods are packed with hundreds of printf calls, and the elog method only works with c-style strings. Is there I way that I could temporarily redirect printf calls to a buffer so I could easily send it over elog to the client? If that's not possible, what would be the simplest way to modify the helper methods to end up with a buffer as output?

  • WPF Skin Skinning Security Concerns

    - by Erik Philips
    I'm really new to the WPF in the .Net Framework (get that out of the way). I'm writing an application where the interface is very customizable by simply loading .xaml (at the moment a Page element) files into a frame and then mapping the controls via names as needed. The idea is to have a community of people who are interested in making skins, skin my application however they want (much like Winamp). Now the question arises, due to my lack of Xaml knowledge, is it possible to create malicious Xaml pages that when downloaded and used could have other embedded Iframes or other elements that could have embed html or call remote webpages with malicious content? I believe this could be the case. If this is the case then I two options; either I have an automated process that can remove these types of Xaml files by checking it’s elements prior to allowing download (which I would assume would be most difficult) or have a human review them prior to download. Are there alternatives I’m unaware of that could make this whole process a lot easier?

  • Implementing a Suspension or Penalty System for Users in ASP.NET MVC

    - by Maxim Z.
    I'm writing a site in ASP.NET MVC that will have user accounts. As the site will be oriented towards discussion, I think I need a system for admins to be able to moderate users, just like we have here, on Stack Overflow. I'd like to be able to put a user into a "suspension", so that they are able to log in to the site (at which point they are greeted with a message, such as, "Your account has been suspended until [DATE]"), but are unable to do the functions that users they would normally be able to do. What's the best way of implementing this? I was thinking of creating a "Suspended" role, but the thing is, I have a few different roles for normal users themselves, with different privileges. Have you ever designed a feature like this before? How should I do it? Thanks in advance.

  • PHP - Cannot use Heredoc within a class method?

    - by Dan
    I'm writing the code for a controller method and I need to use it to send an email. I'm trying to use heredoc syntax to fill in the email body, however, the closing tag doesn't seem to be recognized. $this->email = new Email(); $this->email->from = 'Automated Email'; $this->email->to = '[email protected]'; $this->email->subject = 'A new user has registered'; $this->email->body = <<<EOF Hello, a new user has registered. EOF; $this->email->send(); Everything from the opening <<< EOF down (till the end of the file) is displayed as if it was in quotes. Can anyone see why this is not working? Any advice appreciated. Thanks.
