Create a richer web interface

AJAX represents the capability to leverage the ubiquitous support for JavaScript in web
browsers to create a more interactive user experience. Client applications built to leverage
AJAX still have a client-server paradigm. However, with AJAX the client can update
portions of a given page without appearing to have posted back to the server (of course, it
typically does). In addition, most AJAX-enabled applications put more processing on the
client for things like toggling sections of a page, working with tabs, auto-completing data
entry, popping up dialogs, and more. The result is a step forward in interactivity for a user.

Printing and Graphics

Drawing and Printing in C# By James Foxall , Wendy Haro-Chun Date: Feb 15, 2002 Sample Chapter is provided courtesy of Sams . Return to the article C# provides an amazingly powerful array of drawing capabilities. In this "one-hour" excerpt by James Foxall and Wendy Haro-Chun, you learn the basic skills for drawing shapes and text to a form or other graphical surface. C# provides an amazingly powerful array of drawing capabilities. However, this power comes at the price of a steep learning curve. Drawing isn't intuitive; you can't sit down for a few minutes with the online Help text and start drawing graphics. After you learn the basic principles involved, however, you'll find that drawing isn't that complicated. In this hour, you'll learn the basic skills for drawing shapes and text to a form or other graphical surface. You'll learn about pens, colors, and brushes. In addition, you'll learn how to persist graphics on a form—and even how

Solution Items

Solution Items In practice, the content you will add most often to a solution is project related. But items can be added directly to a solution as well. Collectively, the term solution items refers to any nonproject file that is attached to a solution. Because we know that solutions can't be compiled, it stands to reason that files added at the solution level serve no practical purpose from a compilation perspective. There are various reasons, however, that you may want to add solution items to your solution. For instance, this is a convenient way to store documentation that applies to the solution as a whole. Because you can add any type of file to a solution, this could take the form of documents, notes to other developers, design specifications, or even source code files from other solutions that may have some impact or bearing on the work at hand. By default, Visual Studio supports a few types of solution items that can be created directly from within the IDE. They

Printing in C#

Printing Using C# - Creating a Printing Application           Printing Using C# (Page 1 of 7 ) In this article Matthew shows us how to build a print engine in C# allowing us to print our application data easily. Editor's Note: This article's code has been updated to work with the final release of the .Net framework. Those of you who have done any programming with the Win32 API will be familiar with the concept of the Device Context, also known as the "DC". A Device Context allows a developer to draw things like text, lines, rectangles, curves, etc. on both the screen and the printer, or even in memory in preparation for later drawing to either of these devices. This was a pretty powerful arrangement that allowed a developer who knew how to draw application output on the screen to draw application output on a printer. With .NET, we're given a variety of graphics classes that eventually allow drawing of certain graphics primitives onto device contexts. T
