• Where to place java applet policy file?

  - by makdere

  Hi all, I am working on an artificial intelligence project which is a logic game and aims two user connecting to the server on the network who acts as an Admin and then start to play one by one. In order to create connections, i have a server code which is just listening on localhost:8000 and assigning team values to the clients as they arrive. After connecting, clients make their move under Admin's control. The question is that when i try to put my code to work in the browser it fails with the following error: java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:8000 connect,resolve) Even though i have created my own policy, first granting only Socket access permission to the codebase of my project folder (file:///home/xxx/projects/-), after it didnt work i granted all permissions from all codebase. I tried placing my policy file both in the home directory and in the same directory where my applet code resides. Appreciate any tips, thanks.

• How sophisticated should be DAL?

  - by Andrew Florko

  Basically, DAL (Data Access Layer) should provide simple CRUD (Create/Read/Update/Delete) methods but I always have a temptation to create more sophisticated methods in order to minimize database access roundtrips from Business Logic Layer. What do you think about following extensions to CRUD (most of them are OK I suppose): Read: GetById, GetByName, GetPaged, GetByFilter... e.t.c. methods Create: GetOrCreate methods (model entity is returned from DB or created if not found and returned), Create(lots-of-relations) instead of Create and multiple AssignTo methods calls Update: Merge methods (entities list are updated, created and deleted in one call) Delete: Delete(bool children) - optional children delete, Cleanup methods Where do you usually implement Entity Cache capabilities? DAL or BLL? (My choice is BLL, but I have seen DAL implementations also) Where is the boundary when you decide: this operation is too specific so I should implement it in Business Logic Layer as DAL multiple calls? I often found insufficient BLL operations that were implemented in dozen database roundtrips because developer was afraid to create a bit more sophisticated DAL. Thank you in advance!

• How to determine whether a .NET exception is being handled?

  - by romkyns

  We're investigating a coding pattern in C# in which we'd like to use a "using" clause with a special class, whose Dispose() method does different things depending on whether the "using" body was exited normally or with an exception. To the best of my understanding, the CLR keeps track of the current exception being handled until it's been consumed by a "catch" handler. However it's not entirely clear whether this information is exposed in any way for the code to access. Do you know whether it is, and if so, how to access it? For example: using (var x = new MyObject()) { x.DoSomething(); x.DoMoreThings(); } class MyObject : IDisposable { public void Dispose() { if (ExceptionIsBeingHandled) Rollback(); else Commit(); } } This looks almost like System.Transactions.TransactionScope, except that success/failure is not determined by a call to x.Complete(), but rather based on whether the using body was exited normally.

• Need to copy remotely hosted file vis Shell Command

  - by pnm123

  Hello, There is a file that hosted remotely on a server that is not supporting Shell Access. I bought a new server that supports Shell Access so now I want to copy a file that is on the non-supporting server to new server via a Shell Command using Putty. File url is like this http://www.domain.com/file.gzip and it is username/password protected. If I be more specified, I want to copy a backup of a home directory from cPanel to my new server via Shell command. I have done this few months ago but I don't remember it now and also I failed to google it. Thank you, Prasad

• CodeIgniter's Scaffolding not working

  - by 01010011

  Hi, I keep getting a 404 Page Not Found whenever I try to access CodeIgniter's Scaffolding page in my browser, like so: localhost/codeignitor/index.php/blog/scaffolding/mysecretword I can access localhost/codeignitor/index.php/blog just fine. I followed CodeIgnitor's instructions in their "Create a blog in 20 minutes" by storing my database settings in the database.php file; and automatically connecting to the database by inserting "database" in the core array of the autoload.php; and I've added both parent::Controller(); and $this-load-scaffolding('myTableName') to blog's constructor. It still gives me this 404. Any suggestions?

• Java synchronized method lock on object, or method?

  - by wuntee

  If I have 2 synchronized methods in the same class, but each accessing different variables, can 2 threads access those 2 methods at the same time? Does the lock occur on the object, or does it get as specific as the variables inside the synchronized method? Example: class x{ private int a; private int b; public synchronized void addA(){ a++; } public synchronized void addB(){ b++; } } Can 2 threads access the same instance of class x performing x.addA() and x.addB() at the same time?

• BackgroundWorker and instance variables

  - by Alastair Pitts

  One thing that's always confused me is how a BackgroundWorker seems to have thread-safe access to the instance variables of the surrounding class. Given a basic class: public class BackgroundProcessor { public List<int> Items { get; private set; } public BackgroundProcessor(IEnumerable<int> items) { Items = new List<int>(items); } public void DoWork() { BackgroundWorker worker = new BackgroundWorker(); worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted); worker.DoWork += new DoWorkEventHandler(worker_DoWork); worker.RunWorkerAsync(); } void worker_DoWork(object sender, DoWorkEventArgs e) { var processor = new ProcessingClass(); processor.Process(this.Points); //Accessing the instance variable } void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { //Stuff goes here } } Am I erroneous in my assumption the the call to processor.Process(this.Points); is a thread-safe call? How don't I get a cross-thread access violation? I'm sure it's obvious, but it always has confused me.

• Django: accessing session variables from within a template?

  - by AP257

  Hi all If I set a session variable in Django, like: request.session["name"] = "name" Is there a way I can access it from within a template, or do I have to retrieve it from within a view, and then pass it to a template? Asking because I have around 10 little session variables that I'd like to access within a template, and passing all 10 from the view to the template could get a bit messy. (I have to use session variables because it's a HttpResponseRedirect, but storing the variables in a database is overkill for my purposes.) So - any way to grab session variables directly within a template?

• Read OAuth2.0 Signed_Request Facebook Registration C# MVC

  - by Josh

  My question is very similar this but I guess I need to take it one step further. Facebook says "The data is passed to your application as a signed request. The signed_request parameter is a simple way to make sure that the data you're receiving is the actual data sent by Facebook." After a user has logged into my asp c# MVC site and clicked "Register", the redirect-url is http://site/account/register. At that point (the post to the account/register control), I would like to gather the user's information using the signed request so that I can register them with my site locally. I cannot figure out how to access the data facebook makes available. $data = json_decode(base64_url_decode($payload), true); What is the equivalent in C#? What type of variable/data is facebook passing in the post? And how do I access "$payload"?

• An Efficient data structure for Sorted List

  - by holydiver

  I want to save my objects according to a key in the attributes of my object in a sorted fashion. Later on I'll access these objects sequentially from max key to min key. I'll do some search tasks as well. I consider to use either AVL tree or RB Tree. As far as i know they are nearly equivalent in theory(Both have O(logn)). But in practice which one might be better in performance in my situation. And is there a better alternative than those, considering that I'll mostly do insert and sequentially access to the ds.

• Using file-path to images stored within the Application Settings

  - by Bill

  I am trying to develop an application that uses a number of images that are stored in a seperate remote file location. The file-paths to the UI elements are stored within the Application Settings. Although I understand how to access and use the file-path from Settings in C# (Properties.Settings.Default.pathToGridImages + "OK.png"), I am at a loss to figure out how to utilize the Settings paths in WPF, and can only seem to access the file if I include the file-path, such as: <Grid.Background> <ImageBrush ImageSource="C:\Skins\bottomfill.png" TileMode="Tile" /> </Grid.Background> I would have thought that concatenating "Properties.Settings.Default.pathToGridImages" with "bottomfill.png" in WPF could be done much like it can be done in C#. Can anyone please point me in the right direction?

• Must I loop to search results for a specific value?

  - by tag

  I have a table in the database: name Opinion Tim Tim has an opinion John other random text Dan Dan's random text Al Al says something else I call this data and get it back in getRecords.lastResult To access John's opinion, I could use: getRecords.lastResult[1].opinion But that's only because I know that John is the second record (record 1), but this may change. So the right way is to search through the results to first find the record index for John, then access his opinion. My guess is I need some sort of a loop? Is there an easier way to search for John directly without a loop?

• Sign in as different user when using Integrated Windows Authentication

  - by Sam

  I have restricted access to a site by using Integrated Windows Authentication and turning off anonymous access. This way I can then show them their real name (from looking up on Active Directory and using the server variable LOGON_USER) and do other related Active Directory tasks. How can I then prompt again for their user credentials, through a 'sign in as other user' link , showing the browser prompt (like you would get on a browser like Chrome or Firefox, or if the site was not in the 'Intranet' zone in IE) rather than a Web Form? Since SharePoint offers this functionality, I assume there is a way to do this through code, but I don't know what code can do this (using C#). I can send a 401 header which makes the prompt appear, but how do you then confirm if they are logged in?

• PDCurses TUI with C++ Win32 console application

  - by Bach

  I have downloaded pdcurses source and was able to successfully include curses.h in my project, linked the pre-compiled library and all good. After few hours of trying out the library, I saw the tuidemo.c in the demos folder, compiled it into an executable and brilliant! exactly what I needed for my project. Now the problem is that it's a C code, and I am working on a C++ project in VS c++ 2008. The files I need are tui.c and tui.h How can I include that C file in my C++ code? I saw few suggestions here but the compiler was not too happy with 100's of warnings and errors. How can I go on including/using that TUI pdcurses includes!? Thanks EDIT: I added extern "C" statement, so my test looks like this now, but I'm getting some other type of error #include <stdio.h> #include <stdlib.h> using namespace std; extern "C" { #include <tui.h> } void sub0(void) { //do nothing } void sub1(void) { //do nothing } int main (int argc, char * const argv[]) { menu MainMenu[] = { { "Asub", sub0, "Go inside first submenu" }, { "Bsub", sub1, "Go inside second submenu" }, { "", (FUNC)0, "" } /* always add this as the last item! */ }; startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); return 0; } Although it is compiling successfully, it is throwing an Error at runtime: 0xC0000005: Access violation reading location 0x021c52f9 at line startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); Not sure where to go from here. thanks again.

• Parameters with dots on the URI

  - by robertokl

  In my application, there is a resource, machine, and a nested resource from machine: ip. I want to be able to access the URI of an Ip typing the ip address. The URI should be something like this: /machines/m123/ips/192.168.0.1.xml Where "m123" is the name of the machine and "192.168.0.1" is one of the ips of that machine. The problem here is that rails miss understand the dots from the ip and the format. When I try to access this page, i get: No route matches "/machines/m123/ips/192.168.0.1.xml" And if I replace the dots for any other character it works, witch means that rails isn't handling the dots on the URI. Is there any way to enter a more complex regexp on the routes to make sure rails can treat it the way I want? I'm using rails 2.3.5 and ruby 1.8.7. Thank you.

• SSIS Handling Extenal Issues

  - by durilai

  I have an SSIS package that works fine. The package runs every night and takes about 4 hours to complete. I have am a newb to SSIS, so I want to see what my options are. I am not finding anything on the web about these two issues, so any advice is greatly appreciated. What to do when I have an external issue such as a power failure/accidental restart. Is there a way to alert someone or have the package begin again on restart. A couple weeks ago there was a process that got hung and locked table, making the process not execute. How is the best way to handle ensuring I have the proper access before starting and if not, get the access. I am ok with killing the processes etc. Looking for best practice info. Thanks

• NHibernate filters don't work with Session.Get

  - by Khash

  I'm trying to implement a Soft-deletable repository. Usually this can be easily done with a Delete Event listener. To filter out the deleted entities, I can add a Where attribute to my class mapping. However, I also need to implement two more methods in the repository for this entity: Restore and Purge. Restore will "undelete" entities and Purge will hard-delete them. This means I can't use Where attribute (since it block out soft-deleted entities to any access) I tried using filters instead. I can create a filter and enable or disable it within session to achieve the same result. But the problem is filters don't have any effect on Session.Get method (they only affect ICriteria based access). Any ideas as to how solve this problem? Thanks

• Is it possible to programmatically talk to MSN messenger / Live messenger?

  - by Ceilingfish

  Hi chaps, I've been researching how to interact with the MSN messenger / Live messenger service programmatically and I can't find any real documentation on this. The documentation for the Live services only seem to implement in Javascript (they're here: http://dev.live.com/Messenger/) It would be possible to reverse engineer this API to obtain the web services that it is actually using, but I am guessing that they didn't provide the sources for a reason (which means that those web services aren't meant for direct access). However I can't find any other official APIs that allow programmatic access (more specifically no APIs that mention sockets, web services, or a proper programming language like Java or .Net). Does anyone know if an API like that exists?

• Binary search of unaccesible data field in ldap from python

  - by EricR

  I'm interested in reproducing a particular python script. I have a friend who was accessing an ldap database, without authentication. There was a particular field of interest, we'll call it nin (an integer) for reference, and this field wasn't accessible without proper authentication. However, my friend managed to access this field through some sort of binary search (rather than just looping through integers) on the data; he would check the first digit, check if it was greater or less than the starting value, he would augment that until it returned a true value indicating existence, adding digits and continuing checking until he found the exact value of the integer nin. Any ideas on how he went about this? I've access to a similarly set up database.

• How to find modal dialog opener from javascript?

  I have a page that opens a modal dialog. After the operations done on dialog I want to refresh the opener page. But when I open the popup by using "openDialog" I cannot access to the opener by using window.opener on popup page. It appears "undefined" when I wanted to access. (I dont want to use "popup" method in this case. I want it to be a dialog by the way. using "popup" is my second plan.) What is the best practice to get rid off this issue?

• Checking for Magento login on external page

  - by LinuxGnut

  I'm hitting a wall here while trying to access items from Magento on an external page (same server, same domain, etc, etc). I want to see if the user is logged into Magento before showing them certain parts on the site. Keep in mind that this code exists outside of Magento. Mage::app("default"); Mage::getSingleton("core/session", array("name" = "frontend")); if (empty($session)) { $session = Mage::getSingleton("customer/session"); } if($session-isLoggedIn()) echo "hi"; $cart = Mage::helper('checkout/cart')-getCart()-getItemsCount(); echo $cart; $cart returns 0, where I definitely have products in my cart. isLoggedIn() also returns false. What am I doing wrong here? Is there an option in Magento that I need to turn on or off to be able to access this information outside of Magento?

• API for accessing PHP documentation?

  - by Chad Johnson

  I'm done some Googling, and I've found nothing. I'm scoping out writing a plugin for an editor I use, and I am wondering whether there is a way I can access the PHP documentation via an API? For instance, I'd like to get raw access to the information (besides the comments) located here: http://php.net/file_exists. php.net seemingly uses MediaWiki which provides an API. The tutorial provides the example URL, http://en.wikipedia.org/w/api.php?action=login&format=xml. This does not work for php.net, however (http://php.net/w/api.php?action=login&format=xml). I'm just looking for a little information on how to interface with the PHP documentation.
