The perfect crypt algorithm, possibly unbreakable cipher candidate. Cipher based purely on hash, bit rotation, negation and xoring. Extremly fast, extremly small, with crc32. No more S-boxes, produces no patterns. This version does not implement any CBC. If you want to, you are on your own (or wait until ultimate perfect crypt is released). Would there be any weakness in hash algorithm, please feel free to write a feedback. Swapping hash for other one is just a matter of minutes. This is a priva... |

With the release of Windows Vista® and the upcoming release of Windows Server® 2008, Microsoft has enriched the Windows® platform with so much new technology for developers of managed applications that it's easy to overlook advancements that the native Windows developer can benefit from. The thread pool component that has been part of the platform since the release of Windows 2000, for example, has undergone a complete rearchitecture. The new implementation brings with it a new thread pool API t... |

Knowing that I love to play with such things, a friend recently asked me to help write a simple tool that could export to Microsoft® Excel® a sortable list of all the members of a new assembly that she was required to document. The tool needed to provide information about the properties, methods, events, and interfaces, and list all the parameters for each of the members. Having played with reflection before, it seemed like fun. As I began, though, I kept finding member names that were formatted... |

A good text editor is an essential tool for every programmer. A programmer's choice of text editor is also one of the more frequent debates you will hear in the halls of conferences and workplaces. TextMate, a Mac OS X text editor, has quickly risen to popularity on that platform based on its ease of use and powerful extensibility capabilities. E Text Editor is a new text editor that tries to bring that same simplicity and powerful extensibility to the Windows® platform. E Text Editor lays a sol... |

This article is about changing the color of a GridView row on mouse click without having a postback on the page. In order to achieve this we will be using some javascript and off course the GridView Control itself. GridView is a server side control that contains Rows and Columns. In some cases we want to do something more than the straight forward functionality of the GridView control depending on the functional/UI requirements of the application.... |

This is a very basic example of how to use the System.ComponentModel.BindingList. This is the first in a series of articles that will walk the newbie developer from simple data binding to creating a Parent/Child base business object. The reason I'm writing these articles is to hopefully help other developers to understand how to create business objects. If you have ever looked at some of the free frameworks out there that you can download and use, such as CSLA (http://www.lhotka.net/cslanet/), I... |

when using the error text and icon feature you want an immediate feedback to the user that something that they typed into a cell is incorrect. By default when setting the ErrorText property the error icon will not appear if the cell is in edit mode such as a text box or combo box cell. The below sample demonstrates how you can set a cell’s padding in the CellValidating event to provide spacing for the error icon. Since padding by default affects the location of the error icon the sample uses the... |

I am writing some code that writes strings from Registry keys, value names, and value data strings into an XML document that I operate on programmatically and sometimes display in an HTML report. I also sometimes need to regenerate the original data string from the XML document. My problem is that there are valid ANSI characters such as 0x07 (BEL) that appear in these Registry strings which are not valid XML characters and, according to the specification, are not valid to escape.... |

The vast majority of managed applications run with full trust, but based on my experience teaching .NET security to developers with a broad range of experience, most really don't understand the implications of fully trusted code. So I've pulled together a number of examples where fully trusted code can skirt around common language runtime (CLR) security features, starting each with a question that seems to have an obvious answer.... |

In the world of connected Web services, security is a central issue. However, transaction handling, reliable messaging, and performance are other issues that present significant challenges. All of these issues are helped by addressing the need for fine-grained, dynamic authorization. In this article, I show you how to engineer an approach for the declarative specification of authorization requirements for individual service endpoints. I deliberately use the verb "engineer" as opposed to craft or... |

Security is important. Most developers don't like security. It requires a lot of thought. It requires study. Most developers would rather just "write code", and leave security to "somebody else". Unfortunately, if you are a developer and your job is to produce an application, then guess who that "somebody else" usually is? It's YOU. Even behemoth Microsoft got the message loud and clear. They've made security the single most important thing, above everything else. Wanna know why .NET Server, whi... |

Microsoft now disapproves of the use of ConfigurationSettings (in the System.Configuration namespace) for the retrieval of application and machine configuration settings (from the application.exe.config and machine.config files respectively). The .Net Framework 2.0 now exposes a ConfigurationManager class that "replaces" ConfigurationSettings.... |

IEnumerable: This is a base System.Collection namespace interface. It enables foreach iterations over an underlying collection of objects. To be able to use foreach against a collection in a class or struct, that class or struct must implement the IEnumerable interface. The IEnumerable interface requires that you implement just one method: GetEnumerator(). GetEnumerator() returns an object that implements the IEnumerator interface (discussed below).... |

I've had some interesting discussions recently about the move from the "error code" style of error handling to the use of exceptions in the .NET world, and that's the main reason I've decided to devote a couple of columns to the subject (the secondary reason being that my column is due tomorrow, and I haven't thought of any other topics).This month, we'll talk about the how's and why's of using exceptions, and next month we'll talk about the ins and outs of writing exception classes.... |
