  • Creating a shared HSQLDB database

    - by Robert Munteanu
    In-process HSQLDB database are not expected to be opened by others, even for file-based storage. The documentation hints that this is possible: Server Modes, Advanced Topics, but I've not yet found a URL for how to activate this behaviour. Did anyone do this so they can share how to?

  • asp.net mvc viewdata best practices

    - by user319353
    Hi: Am trying to understand the ASP.NET MVC ViewData with respect to its size. Since this object is passed between Controller to View, how big this could be? Say for example, if DataTable is passed from Model, and Controller is going to pass it to View. Is there any best practices OR any one had any bad experience to share here? Thanks in advance.

  • C# How to download files from FTP Server

    - by user3696888
    I'm trying to download a file (all kinds of files, exe dll txt etc.). And when I try to run it an error comes up on: using (FileStream ws = new FileStream(destination, FileMode.Create)) This is the error message: Access to the path 'C:\Riot Games\League of Legends\RADS\solutions \lol_game_client_sln\releases\0.0.1.41\deploy'(which is my destination, where I want to save it) is denied. Here is my code void download(string url, string destination) { FtpWebRequest request = (FtpWebRequest)WebRequest.Create(url); request.Method = WebRequestMethods.Ftp.DownloadFile; request.Credentials = new NetworkCredential("user", "password"); request.UseBinary = true; using (FtpWebResponse response = (FtpWebResponse)request.GetResponse()) { using (Stream rs = response.GetResponseStream()) { using (FileStream ws = new FileStream(destination, FileMode.Create)) { byte[] buffer = new byte[2048]; int bytesRead = rs.Read(buffer, 0, buffer.Length); while (bytesRead > 0) { ws.Write(buffer, 0, bytesRead); bytesRead = rs.Read(buffer, 0, buffer.Length); } } } }

  • Automatic User Authentication Framework for Controllers in ASP.NET MVC?

    - by Austin
    In rails I could do something like this to make sure a user is authenticated before accessing an action in the controller: before_filter :checked_logged_in, :only => [:edit, :update] I was wondering if ASP.NET MVC had something similar or if there was a framework out there that could essentially do something like the following: For certain methods with actions that take a certain parameter, I want to point the action to a method, check to see if the user owns that object, and if so, proceed to the controller action. If not, I want to redirect him to another action where I can show him he has invalid credentials. So basically I am looking for a sort of "before_filter." Anyone know of anything out there that can do this? Thanks!

  • The remote server returned an error: (407) Proxy Authentication Required

    - by chris
    I'm getting this error when I call a web service: "The remote server returned an error: (407) Proxy Authentication Required". I get the general idea and I can get the code to work by adding myProxy.Credentials= NetworkCredential("user", "password", "domain"); or by using DefaultCredentials in code. My problem is that the call to the web service works in production without this. It seems like there is a non code solution involving Machine.config, but what is it? At the moment I can't get to the production boxes machine.config file to see what that looks like. I tried updating my machine.config as follows, but I still get the 407 error.

  • listing network shares with python

    - by Gearoid Murphy
    Hello, if I explicitly attempt to list the contents of a shared directory on a remote host using python on a windows machine, the operation succeeds, for example, the following snippet works fine: os.listdir("\\\\remotehost\\share") However, if I attempt to list the network drives/directories available on the remote host, python fails, an example of which is shown in the following code snippet: os.listdir("\\\\remotehost") Is anyone aware of why this doesn't work?, any help/workaround is appreciated.

  • Drupal rendering incomplete views

    - by Paul
    I got tapped to do some quick maintenance on a recently migrated Drupal site. I'm pretty new to Drupal, so hopefully the problem is something that more experienced guys will figure out quick. Behavior is as follows. The public content works fine as far as I can tell. When I go to login, the login form renders correctly, but when I post the form w/ my credentials, I get back a blank page (not a 404; looks like a 200 to the /user URL, but all the gets rendered is empty Head and body tags). If i refresh the page, I get the content of my profile view, but none of the site chrome or CSS. Note that this is not an issue on the site it was migrated from, so it seems like something wasn't copied over correctly. The site's not public, so I can't provide a URL, sorry!

  • Where can I find the transaction protocol used by Automated Teller Machines?

    - by Dave
    I'm doing a grad-school software engineering project and I'm looking for the protocol that governs communications between ATMs and bank networks. I've been googling for quite a while now, and though I'm finding all sorts of interesting information about ATMs, I'm surprised to find that there seems to be no industry standard for high-level communications. I'm not talking about 3DES or low-level transmission protocols, but something along the lines of an Interface Control Document; something that governs the sequence of events for various transactions: verify credentials, withdrawal, check balance, etc. Any ideas? Does anything like this even exist? I can't believe that after all this time the banks and ATM manufacturers are still just making this up as they go. A shorter question: if I wanted to go into the ATM software manufacturing business, where would I start looking for standards?

  • Any way to add tabbed forms in django administration site ?

    - by tomjerry
    When using Django "out-of-the-box" administration forms, the "change form" pages can be rather long for complex models (with a lot of fields). I would like to use tabs in the "change form", so things can be more readable (group fields by tabs...) Instead of doing it all by myself, by modifiying the 'change_form.html' admin template, I was wondering whether somebody has already done that and would like to share the code, or whether an existing Django-plugin already exist. Thanks in advance for you answer

  • does it make sense to send password information during email communication from websites

    - by Samuel
    Most of the online sites on registration do send a link to activate the site and on any further correspondence with the end user they provide information about the site and also provide the login credentials with password in clear text (as given below) Username - [email protected] Password - mysecretpassword What would you do in such a case? From a usability perspective does it make sense to send the password information in clear text or should you just avoid sending this information. I was under the impression that most of the passwords are MD5 hashed before storing in the database and hence the service provider will not have any access to clear text passwords, is this a security violation?

  • Has anyone tried the "objectify" library for Google App Engine?

    - by Spines
    I was using JDO for my google app engine project but got fed up with the additional 5 seconds it adds to my cold start time. I was planning on just writing stuff directly to the database with the low level datastore api, but then I came accross the objectify project ( http://code.google.com/p/objectify-appengine/ ). Apparently its a super light wrapper above the low level api. Does anyone have experiences with this library that they could share?

  • Google apps API problem with read-only feed?

    - by brandonprry
    Hi all, I am beginning to use the google data api (specifically for the finance app). I can read my portfolio's just fine, so I am authenticating correctly (or so I think). However, when i try and create a portfolio, I get a 'feed is read-only' error. The constructor for the service: public class FinanceService : Service, IService { public FinanceService(string applicationName) : base ("finance", applicationName) { this.RequestFactory = new GDataGAuthRequestFactory("finance", applicationName) { ProtocolMajor = 3 }; } } and saving it is private const string _schema = "http://schemas.google.com/finance/2007"; private const string _feed = "http://finance.google.com/finance/feeds/default/portfolios"; AtomFeed atomFeed = new AtomFeed(new Uri(_feed), this.FinanceService); return this.FinanceService.Insert(atomFeed, this as AtomEntry) as PortfolioEntry; Any idea why the atomFeed would come back ReadOnly? The credentials are legit, and I can get my current portfolios without a problem.

  • Amazon S3 as secure backup without multiple invoices

    - by Tom Viner
    I'm storing copies of database backups on Amazon S3 using the Python Boto library. But I worry that if my web server was hacked, those backups could be deleted using the credentials I need to do the upload. Ok, so I know you can grant permissions to another Amazon email address, so I can imagine doing that after an upload then removing the original user's write access BUT in this scenario I now end up with 2 accounts and 2 sets of invoices to give to accounts every month. Is there a solution to this that doesn't require a new Amazon account for each web server I run?
