Student Records Management System in VB 6.0 with Access Database

In this post, we will create an application for Student Record Management System in Visual Basic 6 with Microsoft Access Database.

The list of Modules and Forms used in the program as follows.

(A) frmStudentManagement System
Caption: STUDENT RECORD MANAGEMENT SYSTEM

(B) frmLogin
Caption: LOGIN

(C) frmCourse
Caption: COURSE DETAILS

(D) frmStudentDetails
Caption: STUDENT DETAILS

(E) Module1.Bas

System Design

First, we will design the System Model and simple high-level diagram of each module will be enough. There are many kind of the diagram to model a system especially when you are using Object-Oriented design. These models are specified in Unified Modelling Language (UML) which not scope of this post.

Student must Log In to access the System — A student must Log In to access the System

The Administrator has to log in to the system with username and password provided during registration process. No one is allowed to log in without a proper User ID and Password.

Administrators must provide valid Username and Password

Once the Administrators logged in they can see form for Student Details where they can Insert, Delete, Update and Clear the Student Records. They also have the option to go to First Record, Last Record, Next Record and Previous Record.

Maintain Student Record using Student Details Form

Next, there is an option to maintain the Course Details, when you click a Specific button. We will discuss that later.

Data Model

ER Model

Tables

First steps after creating the data model are to make sure that you create an MS Access Database called StudentDB.mdb. If you have MS Access 2007 or higher version, save your database with the file extension (.mdb).

Create the following table with correct data types as shown in the following figures.

Code for Module1.Bas

The Module1.Bas is the code for connection to Microsoft Access Database. Since you may not want to define this connection on each form that is used in the application.

Public Sub loadcon()
constr = "Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=C:UsersGirishDocumentsStudentDB.mdb;
Persist Security Info=False"
con.Open constr
End Sub

Note : The C:\Users\Peter\Documents\StudentDB.mdb; is path to the Access database , you need to change is according to path of your Student Database.
