In a recent small project, I needed a way to display a series of images in a square area (150x150 pixels). The images in question are uploaded by our customers, and we have no real control over what size or color depth (or even type) they are. While it's easy to force a resize of an image to, say, 150 pixels wide x 150 pixels high, you run the risk of stretching the image incorrectly in one dimension. And if you simply decide to force the width of the image to 150 and leave the height proportion...

This is the second article in a three article series examining a custom ASP.NET server control I developed to make using the Google Maps API easier for .NET developers. This article assumes you have read Part 1 and are familiar with the Google Maps API. You may see references throughout the article to "my control, my GoogleMaps control, my GMap control, etc". I did not create the Google Maps API, I merely created a wrapper for ASP.NET using C#, XML, and XSL....

Object oriented applications usually have inheritance as an important part of their design, including in their domain objects.

Advanced Data Mapping in .NET

Read Reviews | Write Review |  Your Rating: 

Data mapping is an essential part of most applications. For some typical database applications, a good part of the code is devoted to it. We usually perform data mapping manually by taking a value from a form field, or a database column etc, and assign it to a class property, one at a time. There is certainly nothing wrong with this manual approach. But as the functionality of the application changes, it's rather annoying to keep removing, adding and changing the data mapping code. In classic VB...

Server.MapPath does not return the physical path of global.asa, but of the environment in which the first page of the application was loaded.
Actually, there is no one solution (that I can think of), because it is all going to depend on other factors of every specific environment. So I will just list a couple of solutions based on some scenarios that I can think of....

So, why should you use any O/R mapping tool? I am not talking about a specific tool but rather all O/R mapping tools in general. There are a number of reasons for using an O/R mapping tool but before I dive into that, let me give you a brief overview of what an O/R mapping tool really is.
An O/R mapping tool generates persistence objects for your .NET application. It is a modeling and code generation tool that connects to your database and reads its schema, then lets you map objects to databa...
