4-Tier Architecture in ASP.NET with C#

Well, the architecture I am going to demonstrate here is just enhancement of 3-Tier archicture. In this architecture; you no need of writing long function parameters throughout the layers (as in traditionally 3-Tier archicture has to) and the actual objects of the application will be in a separate tier so that in future you can separately use these objects for enhancements. Change in the object definition can be done without touching the entire Business Access Layers ............
Let me explain you step-wise process of creatioin of 4-Tier architecture application.
In this application, I am going to take example of a Person that will have 3 properties: FirstName, LastName, Age. We will create a separate pages to insert these records (default.aspx) into database and list,update,delete records (list.aspx) from database.

Adding Markers to a Map Using the Google Maps API and jQuery

The Google Maps API provides a sophisticated way for developers and webmasters to add custom interactive maps to their websites. Version 3 of the API, released in May of 2009, represents a complete overhaul of the API in response to several years worth of user feedback on the previous version.

In this tutorial we’ll cover a few of the API’s simpler features by showing you how to add a map with a set of location markers to a website. Each marker will have an associated info bubble with the name and address of the location. What’s more, we’ll be loading the location data via Ajax, so this can be used as the first step towards developing a more sophisticated map-based application.

Deleting Rows Duplicate when the table doesn’t have a primary key

Were you ever in need of something like, deleting duplicate rows when the table doesn’t have a primary key. If yes, read on!

This article gives a quick way of deleting duplicate records from a given table, that doesn’t have a primary key. Also, we will NOT use cursors, loops, temporary tables (global or local) but still accomplish the mission. Interesting! isn't it. Please read on!

First lets create a simple table with two columns and name the table as ‘DeleteDupsTable’.

Accessing Webservice by using Sys.Net.WebRequest

Introduction

Let us understand what is Sys.Net.WebRequest. WebRequest is the abstract base class for the .NET Framework's request/response model for accessing data from the Internet. An application that uses the request/response model can request data from the Internet in a protocol-agnostic manner, in which the application works with instances of the WebRequest class while protocol-specific descendant classes carry out the details of the request.

Requests are sent from an application to a particular URI, such as a Web page on a server. The URI determines the proper descendant class to create from a list of WebRequest descendants registered for the application. WebRequest descendants are typically registered to handle a specific protocol, such as HTTP or FTP, but can be registered to handle a request to a specific server or path on a server.

WebRequest Class throws an exception when error occurs. The Status is the property of WebExceptionStatus.

Introduction

As developers, I imagine, most of us strive toward these two goals:

1. Write better code.
2. Write less code.
