Have you ever worked with the Windows XP Embedded operating system? This is essentially a developer-customized, slimmed-down version of the Windows XP operating system intended for use on PC-like devices—game consoles, information kiosks, network appliances, and the like. With the rapid growth in the use of mobile and embedded devices, this platform is increasingly important.

I've discovered that there is a sort of knowledge gap between software test engineers and developers who work with the Windows XP Embedded-based software systems. To help bridge that gap, in this month's column I'm joined by Mike Hall, a Senior Product Manager in the Microsoft® Mobile and Embedded Devices group and an expert on Windows XP Embedded. Together we will explain how you can create lightweight but powerful UI test automation for software systems that run on Windows XP Embedded...

The .NET framework provides rich support for generating and manipulating bitmap images, but it lacks one significant feature that is imperative for image processing - the ability to modify and then save modified bitonal (i.e., black and white or one-bit per pixel) images. Bitonal images are commonly used in document management and document imaging applications for scanned documents. Bitonal images are most commonly stored in the TIFF (Tagged Image File Format) file format with a CCITT Group IV compression algorithm..

When crafting a query in SQL, there are often times when we may need to operate over a set of data that doesn't inherently exist within the system. For example, the database for an eCommerce web application would have the standard tables - Products, Customers, Orders, OrderDetails, and so on - but we may need to run reports on a particular subset of the data or against aggregate data across these tables. Or the reporting queries we need might need to group or filter by results returned by scalar subqueries. Typically, views are used to break down complex queries into digestible chunks or to provide scalar subquery results that can be grouped and filtered. Views, however, are sometimes overkill, as they are permanent objects at the system-level. If we only need to reference this complex query in a single stored procedure or UDF, another option is to use a derived table. Unfortunately, derived tables muddle the readability of the query and must be repeated for each use in a statement..

An outlook bar like control with generic contents and animation effects.

Discussing the MultipleFieldsValidator that validates a group of fields in which at least one is required, like phone number, mobile phone number, or email. It inherits the BaseValidator and uses some new cool ASP.NET 2.0 features.

ASP.NET DropDownList render custom control with OptionGroup feature.

The 4-in-1 ComboBox class is a control that you can add to your projects and tweak its properties for the desired look and feel. The most important feature of this power control is its ability to keep the DropDownBox active while the user checks items.

A simple ComboBox with formatted grouping.

A simple C# program that can extract/save article headers from Newsgroups.

Extended ListView with GUIs for your easy grouping. The control will automatically create a ToolStrip and a ToolStripButton for each column.
