  • Nested class with hidden constructor impossible in c#?

    - by luckyluke
    I' ve been doing some programming lately and faced an issue which i found weird in c#. (at least for me) public class Foo { //whatever public class FooSpecificCollection : List<Bar> { //implementation details } public FooSpecificCollection GetFoosStuff() { //return the collection } } I want the consumer of Foo to be able to obtain a reference to FooSpecificCollection, even perform some operations on it. Maybe even set it to some other property of Foo or smth like that, but not To be able to CREATE an instance of this class. (the only class that should be able to instatiate this collection should be Foo. Is my request really that far-fetched? I know that people way smarter defined c# but shouldn't there be such an option that a parent class can create a nested class instance but nobody else can't. So far I created a solution to make an abstract class, or interface available through the property and implement a concrete private class that is not available anywhere else. Is this a correct way to handle such a situation.?

  • What division operator symbol would you pick?

    - by Mackenzie
    I am currently designing and implementing a small programming language as an extra-credit project in a class I'm taking. My problem is that the language has three numeric types: Long, Double, and Fraction. Fractions can be written in the language as proper or improper fractions (e.g. "2 1/3" or "1/2"). This fact leads to problems such as "2/3.5" (Long/Double) and "2/3"(Long/Long) not being handled correctly by the lexer.The best solution that I see is to change the division operator. So far, I think "\" is the best solution since "//" starts comments. Would you pick "\", if you were designing the language? Would you pick something else? If so, what? Note: changing the way fractions are written is not possible. Thanks in advance for your help,

  • WPF DataGrid Vs Windows Forms DataGridView

    - by Mrk Mnl
    I have experience in WPF and Windows Forms, however have only used the Windows Forms DataGridView and not the WPF DataGrid (which was only included in .Net 4 or could be added to .Net 3.5 from Codeplex, I understand). I am about to devlop an app using one of these controls heavily for large amounts of data and have read performance is an issue with the WPF DataGrid so I may stick to the Windows Forms DataGridView.. Is this the case? I do not want to use a 3rd party control. Does the Windows Forms DataGridView offer significant performance over the WPF DataGrid for large amounts of data? If I were to use WPF I would prefer to use .Net 3.5S SP1, unless the DataGrid in the .Net 4 is significantly better? Also I want to use ADO with DataTable's which I feel is better suited to Windows Forms..

  • Thread problem with XNA C#

    - by Luis
    I'm development a network card game, and for now i've two players connected but there is a problem with one of them, this one can't do anything on the game. Looks that screen was blocked. I'm think that is because a code i used before. That code is: if (InvokeRequired) { this.Invoke(new MethodInvoker(delegate { ... })); return; } The code above is surrounding code to changing Button values, make connection with server and create game window. Without this code a warning is shown. InvalidOperationException was unhandled Cross-thread operation not valid: Control 'startGameButton' accessed from a thread other than the thread it was created on.

  • VPN connection sharing for Ubuntu guest

    - by pzico
    I have Ubuntu 10.04 guest on Windows XP host. I need to use a specific VPN software that works only on Windows. How should I configure virtualbox/guest so that the VPN connection would be visible on guest? I already tried NAT and bridged network settings. With both of these options I get only normal internet connection to work, but sites requiring VPN don't work on guest, only on host.

  • Solera Networks Threat Predictions for 2012, Solutions

    Legitimate sites are often trusted by their visitors, which makes them a perfect target for cybercriminals. Solera lists attacks on legitimate, yet compromised sites as a growing trend for 2012 due to the increased amount of such sites containing unpatched vulnerabilities.

According to Solera, malicious spam is another undesirable item that should increase in 2012. Various methods, such as email, instant messaging, attachments, malicious links, and social networks will cont...

  • C# how to create functions that are interpreted at runtime

    - by Lirik
    I'm making a Genetic Program, but I'm hitting a limitation with C# where I want to present new functions to the algorithm but I can't do it without recompiling the program. In essence I want the user of the program to provide the allowed functions and the GP will automatically use them. It would be great if the user is required to know as little about programming as possible. I want to plug in the new functions without compiling them into the program. In Python this is easy, since it's all interpreted, but I have no clue how to do it with C#. Does anybody know how to achieve this in C#? Are there any libraries, techniques, etc?

  • Does more heat generation mean more wear and tear?

    - by Suhail Gupta
    I read that hardware generally used on PC is not optimized for running Linux. That is the reason the machine emits large amount of heat and doesn't give the battery back up , that we will get while working on windows. ~REF Does it also mean more wear and tear of the hardware (when using linux as compared when using windows ) ? Note : I have personally experienced large heat emission while working with Fedora 16 and Ubuntu 11.xx on my laptop.

    - by Mahmoud Saleh
    I am using Windows Server 2008 R2 Enterprise x64. After installing the Hyper-V role and restarting the machine, I get a blue screen error and an immediate reboot.

The graphics card is an Nvidia GeForce 8400 GS. Does anyone know how I can resolve this issue?

  • Codec Pack with that can easily be deployed via group policy

    - by testguy
    We have a teacher that has a project for doing some basic film editing with windows movie maker. We loaded the avi file onto the computer and Windows is trying to install a codec but can't. I assume I need to install some type of codec pack. I'm looking for suggestions on a codec pack that I can easily deploy through a Win2003 server to WinXP clients. Ideally, this codec pack shouldn't break anything else and be easily removed if need be.

  • Microsoft Unveils New Logo

    Indeed, with those four familiar colored squares - set in a bigger square rather than standing on a point in a diamond - Microsoft's new corporate logo seems almost inevitable. As you'd expect, the company's name makes up part of the logo, but instead of the thick italic letters it has used for the past two and a half decades, it's in a more standard, lighter font. Jeff Hansen, Microsoft's general manager of brand strategy, notes that the point of the new logo is to signal the heritage but also signal the future - a newness and a freshness. It's very fitting when you consider just how many...

  • How to implement smart card authentication with a .NET Fat client?

    - by John Nevermore
    I know very little about smart card authentication in general so please point out or correct me if anything below doesn't make sense. Lets say i have: A Certificate Authority "X"-s smart card (non-exportable private key) Drivers for that smart card written in C A smart card reader CA-s authentication OCSP web service A requirement to implement user authentication in a .NET fat client application via a smart card, that was given out by the CA "X". I tried searching info on the web but no prevail. What would the steps be ? My first thought was: Set up a web service, that would allow saving of (for example) scores of a ping pong game for each user. Each time someone tries to submit a score via the client application, he can only do so by inserting the smart card into the reader. Then the public key is read from the smart card by native c calls through .NET and sent to my custom web service, which in return uses the CA-s authentication OCSP web service to prove the validity of the public key/public certificate (?). If the public key is okay and valid, encrypt a random sequence of bytes with the public key and send it to the client application. If the client application sends back the correctly decrypted random sequence of bytes along with the score of the ping pong game, then the score is saved in the database for the given user. My question is, is this the correct way to do it ? What else should i know about smart card authentication ?

  • Dell All-in-One 810 CD software will no longer install

    - by authentictech
    I have a Dell All-in-One 810 printer from years ago and only recently installed it (a few months ago). Later I had reason to uninstall and re-install the printer but whenever I connect the printer Windows installs the printer drivers from its cache without the CD. How can I remove all traces of the drivers from the cache so that it will install only from the CD and not from the Windows driver cache?

  • Cannot boot Win7 after updating to ubuntu 11.10

    - by angryInsomniac
    I had a dual boot setup on my system, with ubuntu 11.04 and Win7. Yesterday I updated ubuntu to 11.10. Now , I cannot seem to be able to load Win7 , I do see an entry for it on the boot menu. I select that entry and then the screen goes black , with everything coming to a standstill. I tried to wait for it to respond but nothing happened. I went through the forums and tried "grub-update" but when I do that , nothing really happens. I am not sure of this , but I get no output from grub for upto 10 minutes ( can grub-update be made verbose ) How can I fix this and get back to booting both OS'es properly ?

  • How to Use KeePass In Your Browser, Across Your Computers, and On Your Phone

    - by Chris Hoffman
    If you’re using a password manager and it’s not the cloud-based LastPass, it’s probably KeePass. KeePass is a completely open-source password manager that stores all your sensitive data locally. However, this means that it isn’t quite as well-integrated as other solutions. Want LastPass-style browser integration, the ability to synchronize your passwords and have them everywhere, and an app to access your passwords on your phone? You’ll have to string together your own system.

  • Parsing a website

    - by Phenom
    I want to make a program that takes as user input a website address. The program then goes to that website, downloads it, and then parses the information inside. It outputs a new html file using the information from the website. Specifically, what this program will do is take certain links from the website, and put the links in the output html file, and it will discard everything else. Right now I just want to make it for websites that don't require a login, but later on I want to make it work for sites where you have to login, so it will have to be able to deal with cookies. I'll also want to later on have the program be able to explore certain links and download information from those other sites. What are the best programming languages or tools to do this?
