One. Purpose and requirements
1. Learn the basic method of the development management system through the verification of the example program "Student Selection System".
2. Reading, understanding and performing practical operations in accordance with the contents introduced in the textbook P336-363 and this experiment.
3. Learn and master the steps and methods of using the tools provided by the PowerBuilder development environment.
4. Learning and preliminaryly mastered the debugging of the application PowerBuilder for application.
two. Experimental steps
1. Create a workspace and target student in the D disk student directory.
2. Establish Application Objects Student.
3. Built four data windows (D_S, D_C, D_SELECT_STUDENT, D_SELECT_SELECT_STUDENT, D_SELECT_COURSE, showing student tables, curriculum, with parameter student details, selection.
4. In the Student application, the WINDOWS: W_SELECT_COURSE is added to the main window to add the corresponding control.
5. Built another two windows (Windows) w_creat_student, w_creat_course, in the Student application, write scripts in the application object.
6. Add a menu in the Student application.
Debug and run the application, check the correctness of the system.
three. Experimental report requirements

2. Experience.
Run interface:
Main interface:
Student watch management interface:
Course Table Management Interface:
In the machine:
This experiment is mainly based on book examples. Overall, it is still relatively simple, plus the last experiment to understand the PB8.0, how to complete this experiment, from this experiment, is mainly familiar with how PB is established, and skirting procedures And can gain a lot through the problem encountered by the online book inquiry.
