1 PROGRAMMING IN VISUAL BASIC.NET CREATING YOUR FIRST WEB APPLICATION Bilal Munir Mughal 1 Chapter-3

2 Topics  Getting Started with Web Applications  Creating the Sample Web Application  Enhancing Your Web Application 2

3 Getting Started with Web Applications  Windows application  most of the code resides on your local PC  Web application  most of the code resides on a Web server  There are two major advantages to this centralized architecture:  Your code only exists in one place, so it can be updated easily.  Installation of your application by end users is not required. This is because the Web application can send standard Web syntax, such as the Hypertext Markup Language (HTML), which the user's browser already understands. 3

4 Understanding Web Application Projects There are a lot of different ways you can use Visual Basic in a Web site.  ASP.NET – You can create Active Server Pages, which contain Visual Basic code that executes on the server.  Visual Basic Classes – Classes that have been compiled into a DLL file can be installed on your Web server. These classes, which contain business logic and database functions, can be called from ASP.NET pages or exposed as Web services.  Client-Side Scripting – VBScript, a subset of the Visual Basic language, can be used to execute code inside of the user's browser after the Web page has been delivered. This allows you to create a richer UI experience than can be achieved with standard HTML. 4

5 Connecting to Your Web Server  http://servername … for remote web server  http://localhost … for current PC as server  http://ipaddress? 5
