  • How to safely store encryption key in a .NET assembly

    - by Alex
    In order to prevent somebody from grabbing my data easily, I cache data from my service as encrypted files (copy protection, basically). However, in order to do this, I must store the encryption key within the .NET assembly so it is able to encrypt and decrypt these files. Being aware of tools like Red Gate's .NET Reflector which can pull my key right out, I get a feeling that this is not a very safe way of doing it... are there any best practices to doing this?

  • How to edit and display Date in ASP.Net MVC 2

    - by Picflight
    I am storing a date in my database and want the user to be able to edit this date in the Edit View. In the past with ASP.Net web forms I have used 3 dropdownlists for the Month, Day and Year to get the date from the user and to bind it on display. I want to do the same in ASP.Net MVC and not sure how to do it? I am not using any jQuery or Javascript, the design calls for simple postback.

  • Default .NET exception handler

    - by ajs410
    So the other day my C# application crashed. Usually, with a .NET application, if you have an unhandled exception you get a nice error message with a stack trace. However, this time, I got a different dialog that just told me there was an error and offered to attach a Debugger, but there was no stack trace in the dialog and the machine it was running on had no debugger installed. What gives? Why don't I see the default .NET exception handler?

  • Convert between python array and .NET Array

    - by dungema
    I have a python method that returns a Python byte array.array('c'). Now, I want to copy this array using System.Runtime.InteropServices.Marshal.Copy. This method however expects a .NET array. import array from System.Runtime.InteropServices import Marshal bytes = array.array('c') bytes.append('a') bytes.append('b') bytes.append('c') Marshal.Copy(bytes, dest, 0, 3) Is there a way to make this work without copying the data? If not, how do I convert the data in the Python array to the .NET array?

  • .NET Regex Instance Caching

    - by jvenema
    I've read this article, which describes how instance vs static methods get called with a .NET regex. However, what about if the instance itself is static? Does anyone know if .NET does any sort of caching that could potentially cause a memory leak?

  • .NET Automated Build Server Software

    - by KevinDeus
    What good .NET Continous Integration and Automated Build and Deployment Software is out there? We have been using CruiseControl.NET but it is really starting to get on our nerves with the amount of maintenance it needs. We're looking for something that virtually anybody can manage, and it would also really be good to not have to write a NAnt build script. We use Subversion for Source Controll

  • Executing Password Change over Ruby Net-SSH

    - by tesmar
    Hi all, I am looking to execute a password change over Net-ssh and this code seems to hang: Net::SSH.start(server_ip, "user", :verbose => :debug ) do |session| session.process.popen3("ls") do |input, output, error| ["old_pass","test", "test"].each do |x| input.puts x end end end I know the connection works because using a simple exec I can get the output from ls on the remote server, but this hangs. Any ideas? The last message from debug is that the public key succeeded.

  • How to add additional data column in EF using ASP.Net MVC 2

    - by Picflight
    My Table: [LocationId] [Address] [ZipCode] When I show a list of Location's, I also want to show the distance from a given zip code. In Asp.Net Web Forms I had a stored procedure that would return the distance and I would call this SP on ItemDataBound on my GridView. Or, I also would have my SP that is returning the Location list add another column ([Distance]) which I could display in my GridView. How would you do this using Entity Framework and Asp.Net Mvc 2?

  • CruiseControl.NET : Sending email using SVN username to ActiveDirectory mapping

    - by matthewpe
    Is it possible to configure CruiseControl.NET to send an email to the user(s) that did modifications to a broken build by mapping their SVN username to the corresponding Active-Directory alias (hence retrieving the correct, updated email address). Our SVN server is set-up to allow users of a certain Active-Directory group to read and commit changes: I don't want to have to maintain the CruiseControl.NET config every time a user gets added to our Programmers group in Active-Directory. Thanks a lot!
