UPDATE: I am working on a FedEx, UPS and DHL version of this tool. The DHL version should be the next one I release. I will post them here on codeproject.com when I am finished but you can check www.johnnycantcode.com until then for updates and to contact me directly. I was in need of a library that would integrate the USPS Web Tools into my windows form application. (This library will work in ASP.NET web applications also.) The USPS Web tools are fairly easy to integrate but I wanted to create ...

I have been playing with LINQ to SQL for a bit, it is a great and easy to use along with the designer that ships with VS.NET 2008. so i wanted to create a FACADE layer that integrates with LINQ to SQL classes, the old school way is to create a public class (Manager) and this class calls your Database mappers to get/set the required info, now LINQ TO SQL replaces the mapper classes and the way to do your operations is to open the dataContext and start defining queries to perform such operations....

This article introduces a new C#-XML data binding technique based entirely on VTD-XML (http://vtd-xml.sourceforge.net) and XPath. The new approach differs from traditional C# XML data binding tools in that it doesn't mandate schema, takes advantage of XML's inherent loose encoding, and is also more flexible and efficient ....

There are some very nice additions to the new C# 3.0 language. For instance Automatic Properties, Object and Collection Initializers, Extension Methods, Lambda Expressions, Anonymous Types and of course LINQ. As a developer you probably often write code for accessing data with OLEDB, DAO, ODBC, ADO or ADO.NET. Or maybe you are using an object relational mapper like NHibernate or even ActiveRecord. You probably noticed that each time you needed more coding than you wanted. In this demo applicatio...

This article describes an approach to constructing a cool segmented LED displayer that is similar to the LEDs used in alarm clocks and industry monitors. This control can be used to display time, numerical values and even some English characters. I hope it will be helpful in programs such as hardware simulators. In this section, I would like to give a brief introduction to the ideas behind this control. In a 7-segment LED displayer, one character is composed of at most 7 segments, as in the pict...

Without proper preparation, converting a scanned image to text via OCR can produce substandard results. Without the proper tools, preparing a scanned image for OCR can be a complex, if not an impossible task. LEADTOOLS Document Imaging Suite solves both of these problems by providing functions that get the image from the scanner, removes nonessential elements that could cause problems for OCR and finally converts the image to a text or document format with the industry leader OCR engine....

Language integrated query (LINQ) in .NET 3.5 provides querying capabilities to Object Oriented programming languages like C# or VB.NET. This integration of querying capabilities allows compile time checking of query expressions as well as intellisence support from IDE's using the reflection. Linq allows the developer to write query expressions in his own choice of programming language with out having the necessity to learn different databases and query languages. Linq defines a set of standard q...
