This article mainly introduces VB.NET and VB6.0 development how to use ASP.NET 2.0 to build Web applications, the article is very detailed, has a certain reference value, interested friends must read it!

Brief introduction

If you are like me, that means you are mainly developing desktop applications. But desktop developers sometimes need to do Web development, which is quite common. The purpose of this article is to give VB.NET and VB6.0 developers a quick grasp of how to build Web applications with ASP.NET 2.0. For this reason, this article tries to focus on the differences in developing Web applications from the perspective of desktop developers. This article also assumes that your main goal is to build data-based Web pages, and that your primary concern is to enable users to display information in the database. Is this the case with you? Then read on.

Getting started

To perform the steps described in this article, Visual Studio 2005 is required. You also need to download the Visual Studio 2005 Web application project add-in. In order to walk through the operation of displaying information in the database, you also need SQL Server 2005 Express Edition and the Northwind sample database.

Full-featured ASP.NET Web sites can be built with Visual Studio 2005. However, Visual Studio 2005 already comes with a non-project system for building Web sites. For people engaged in desktop development, this also makes the work and experience of building Web sites very different from building desktop applications. The Visual Studio 2005 Web application project add-on greatly improves the similarity between Web site construction and desktop application construction. In the walkthrough in this article, it is assumed that you have installed the add-in.

Walkthrough: creating a simple Web Application

1. If you do not have the Visual Studio 2005 Web application project add-in, download and install it.

two。 Start Visual Studio 2005.

3. On the File menu, click New, and then click Project.

4. In Project Type, select Visual Basic.

5. In templates, select ASP.NET Web applications.

Visual Studio creates a new Web application that contains a single Web page. The designer displays the markup code for the page. You can edit the page in Source view or using the WYSIWYG editor.

6. Click the Design button on the code editor to switch to WYSIWYG view.

At first glance, building Web applications seems to be no different from building desktop applications.

7. Click the design surface and enter "Enter your name:".

8. Drag the Textbox control from the toolbox to behind the text described in the design surface.

9. Click the mouse to place the cursor behind the Textbox control and press ENTER to create a new row.

10. Drag the Button control from the toolbox to the design surface.

11. Click the mouse to place the cursor behind the Button control and press ENTER to create another line break.

twelve。 Drag the Label control from the toolbox below the button on the design surface.

When you start building Web pages, you should soon find one thing: you can't put controls anywhere you want. Desktop applications allow you to place controls in any pixel you want. Web pages, on the other hand, are designed for "streams". In other words, the layout of the page should be formatted dynamically. If there is more free space, the browser will make the lines longer, and if there is less free space, the browser will automatically wrap the lines.

This also means that when laying out labels and text boxes, the Web control is required to be placed in tabular form to control alignment.
