  • Is it possible to use pure Encrypting and Decrypting keys in asymmetric cryptography instead of priv

    - by macropas
    Is it possible to use pure Encrypting and Decrypting keys instead of private and public keys? As I know in .Net asymmetric RSA implementation private key RSAParameters parameters = (new RSACryptoServiceProvider()).ExportParameters(true) is a superset of public key. And using private key we can both encrypt and decrypt our data. But I need key only for decrypting data. How to do it? I experimented on nulling RSAParameters fields, but RSACryptoServiceProvider object can't import such parameters.

  • How to create layout for tower made of blocks

    - by sasquatch90
    I have a tower built from blocks like this : Whole Tower is an array of Towers. Each Tower contains Box[] array containing single Box'es.What layout should I use for this and can you give me any tips on how to create it ? Would it be easier if I would create Grid[][] containing Box'es? But I guess I can't store Box object inside Grid array. I'm just totally confused :/

  • Log to Firefox Error Console from JavaScript

    - by Torsten Marek
    Is it possible to add messages to the built-in error console of Firefox from JavaScript code running in web pages? I know that I there's Firebug, which provides a console object and its own error console, but I was looking for a quick fix earlier on and couldn't find anything. I guess it might not be possible at all, to prevent malicious web pages from spamming the log?

  • What common routines do you put in your Program.cs for C#

    - by Rick
    I'm interested in any common routine/procedures/methods that you might use in you Program.cs when creating a .NET project. For instance I commonly use the following code in my desktop applications to allow easy upgrades, single instance execution and friendly and simple reporting of uncaught system application errors. using System; using System.Diagnostics; using System.Threading; using System.Windows.Forms; namespace NameoftheAssembly { internal static class Program { /// <summary> /// The main entry point for the application. Modified to check for another running instance on the same computer and to catch and report any errors not explicitly checked for. /// </summary> [STAThread] private static void Main() { //for upgrading and installing newer versions string[] arguments = Environment.GetCommandLineArgs(); if (arguments.GetUpperBound(0) > 0) { foreach (string argument in arguments) { if (argument.Split('=')[0].ToLower().Equals("/u")) { string guid = argument.Split('=')[1]; string path = Environment.GetFolderPath(Environment.SpecialFolder.System); var si = new ProcessStartInfo(path + "\\msiexec.exe", "/x" + guid); Process.Start(si); Application.Exit(); } } //end of upgrade } else { bool onlyInstance = false; var mutex = new Mutex(true, Application.ProductName, out onlyInstance); if (!onlyInstance) { MessageBox.Show("Another copy of this running"); return; } AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException; Application.ThreadException += ApplicationThreadException; Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } } private static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { try { var ex = (Exception) e.ExceptionObject; MessageBox.Show("Whoops! Please contact the developers with the following" + " information:\n\n" + ex.Message + ex.StackTrace, " Fatal Error", MessageBoxButtons.OK, MessageBoxIcon.Stop); } catch (Exception) { //do nothing - Another Exception! Wow not a good thing. } finally { Application.Exit(); } } public static void ApplicationThreadException(object sender, ThreadExceptionEventArgs e) { try { MessageBox.Show("Whoops! Please contact the developers with the following" + " information:\n\n" + e.Exception.Message + e.Exception.StackTrace, " Error", MessageBoxButtons.OK, MessageBoxIcon.Stop); } catch (Exception) { //do nothing - Another Exception! Wow not a good thing. } } } } I find these routines to be very helpful. What methods have you found helpful in Program.cs?

  • What is a 'better' approach to query/save from server: DTO or Wcf Data Services?

    - by bonefisher
    From my perspective, the Data Services and their query approach is useful when querying simple object graphs from your server-side domain model. But when you want to query complex dependencies I couldn't create anything good out of it. The classic DTO approach is fine-grained and can handle everything, but the downside is that you have to create Dto classes for every type of server-request which is time consuming and you have to synchronize the Dto type with your domain entity/business logic.

  • Applying styles to a GridView matching certain criteria

    - by NickK
    Hi everyone. I'm fairly new to ASP.Net so it's probably just me being a bit stupid, but I just can't figure out why this isn't working. Basically, I have a GridView control (GridView1) on a page which is reading from a database. I already have a CSS style applied to the GridView and all I want to do is change the background image applied in the style depending on if a certain cell has data in it or not. The way I'm trying to handle this change is updating the CSS class applied to each row through C#. I have the code below doing this: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { GridViewRow row = e.Row; string s = row.Cells[7].Text; if (s.Length > 0) { row.CssClass = "newRowBackground"; } else { row.CssClass = "oldRowBackground"; } } In theory, the data from Cell[7] will either be null or be a string (in this case, likely a person's name). The problem is that when the page loads, every row in the GridView has the new style applied to it, whether it's empty or not. However, when I change it to use hard coded examples, it works fine. So for example, the below would work exactly how I want it to: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { GridViewRow row = e.Row; string s = row.Cells[7].Text; if (s == "Smith") //Matching a name in one of the rows { row.CssClass = "newRowBackground"; } else { row.CssClass = "oldRowBackground"; } } It seems as if the top piece of code is always returning the string with a value greater than 0, but when I check the database the fields are all null (except for my test record of "Smith"). I'm probably doing something very simple that's wrong here, but I can't see what. Like I said, I'm still very new to this. One thing I have tried is changing the argument in the if statement to things like: if (s != null), if (s != "") and if (s == string.empty) all with no luck. Any help is greatly appreciated and don't hesitate to tell me if I'm just being stupid here. :)

  • FTP a text file to a server using VBA in Excel

    - by Anindya
    I have an Excel worksheet where the user enters certain data, which I want to store in a text file and upload to a server using FTP. One site suggested adding a reference to "Microsoft Internet Transfer Control" and then define an "Inet" object to do the FTP. However, I am unable to find a reference with this name in "Tools - References" in the VB Editor. Does anyone know of a solution for this problem? Thanks in advance.
