Hey I have run into a rather weird little problem. In the following code I can not understand how e can be null; try { //Some Code here } catch (Exception e) { //Here e is null } As far as I know, throw null will be converted to throw new NullReferenceException(). The problem seems to be related to multithreading, as removi...
I need to store a hash of a single password in a .Net WinForms application. What's the most secure way to do this? In particular: Salt, HMAC, or both? How much salt? How many iterations? What encoding? (The password is plain ASCII) I assume that the algorithm should be either SHA512 or HMACSHA512. ...
Given the code block below (source: http://www.asp.net/learn/mvc/tutorial-31-cs.aspx)... I receive this error: Using the generic type 'System.Collections.Generic.List' requires '1' type arguments I can pacify this by simply modifying my declaration to read as: var groups = new List<string>(); Is this just a case of invalid syntax in the...
The following application is not rendering the information that I am getting back from a web service into the datagrid. I know I am being able to connect to the webservice because I am getting the count for the class array.

I have a method which turns any Latin text (e.g. English, French, German, Polish) into its slug form, e.g. "Alpha Bravo Charlie" => "alpha-bravo-charlie" But it can't work for Cyrillic text (e.g. Russian), so what I'm wanting to do is transliterate the Cyrillic text to Latin characters, then slugify that. Does anyone have a way to do ...

I have a function that wraps a call to one of my socket types. If there is an error, I want to be able to print a warning and retry. In the warning, I want to have the method name. However, it was declared as a lambda. Is this even possible? How I call the function (assume in function called myMain): SafeSocketCommand(() => this.mySock...
I am using CC.Net with MSBuild tasks to build an application that is composed of a number of solutions and projects. We are using the AssemblyInfo MSBuild Community task to update version info in AssemblyInfo.cs.

Hello all, I'm looking for an idea for a final project in .net. I thought about building an IM AJAX app with .net but am kind of getting the feeling that the only way to do the video/audio chat is with flash and action script...

Hi, I have sort of a philosophical question, which also need to consider the performance impact. We are designing a new system with many sub-services that are not related to each other, yet, some may use each other (We are using unity to avoid any decoupling). My main question is: Should we break them into separate DLL's, where each ...

For those not familiar with NetRun, NetRun.exe is basically an application "runner" that is installed on user computers (e.g. to c:\Program Files\NetRun\NetRun.exe). The user simply starts...
Why cannot C# generics derive from one of the generic type parameters like they can in C++ templates? I mean I know it impossible because CLR does not support this, but why? I am aware of the profound differences between C++ templates and C# generics - the former are compile time entities and must be resolved during the compilation, whi...
The System.Collections.ObjectModel.KeyedCollection class is a very useful alternative to System.Collections.Generic.Dictionary, especially when the key data is part of the object being stored or you want to be able to enumerate the items in order. Unfortunately, the class is abstract, and I am unable to find a general concrete implementa...
