4.3.1 Application User Interface generate, create none none for none projectsasp.net data matrix generating We made a demo for th none none is sample data-driven application in Section 4.1. This project is composed of ve forms: LogIn, Selection, Faculty, Student, and Course.

The project is designed to map a Computer Science and Engineering Department in a university and to allow users to scan and browse all information about the department, including faculty members, courses taught by selected faculty members, students, and courses taken by the students. Each form, except the Selection form, is associated with one or two data tables in the sample database CSE DEPT, which was developed in 2. The relationships between the forms and tables are shown in Table 4.

2. Controls on each form are bound to the associated elds in a certain data table located in the CSE DEPT database. As the project runs, a data query will be executed via a dynamic SQL statement that is built during the con guration of each TableAdapter in the Data Source wizard.

The retrieved data will be re ected in the associated controls that have been bound to those data elds. The database used in this sample project, which was developed in 2, is an SQL Server 2005 Express database since it is compatible with the SQL Server 2005 database and, most important, it is free and can be easily downloaded from the Microsoft Knowledge Base site. You can use any kind of database, such as Microsoft Access, SQL Server 2005, or Oracle, for this sample project.

The only thing you need to do is to select the desired data source when you add and connect that data source to your project. Let s begin to develop this sample project with ve forms..
