Student Attendance Management System Using VB 6 Part – 3

by

In Student Attendance Management System Using VB 6 Part 3, we will learn to create an interface for the attendance system that will meet the user requirements.

Here is the list of interfaces that we need to create.

  • Login for Student (frmLogin)
  • Login for Teacher (frmTLogin)
  • Login for Admin (frmALogin)
  • Main Screen (frmSplash)
  • View Attendance (frmViewAttendance)
  • Today’s Attendance (frmTodayAttendance)
  • Student Record Management (frmStudent)
  • Teacher Record Management (frmTeacherRecord)
Figure1-Names of forms for Attendance Management Project

For each of the above interfaces which also the VB form we will list out the following things.

  • System Diagram
  • Form Design
  • Components and its properties
  • Visual basic code

The system design is a high-level overview of individual components which show how each component of interface is related.

Connect To MS Access Database

Before we do anything we must first establish connection with MS Access database that we created earlier. If you did not create a database go to attendance management part-2 and create a database first.

To connect to database we will create a VB 6 module. Modules in VB are files that contain source codes. You can use them throughout your project without repeating them on each form. We must create a single module to connect with ms access database automatically.

To create a module, go to project explorer, right-click Form, select Add, and click Module.

Figure2-Create a Module in VB 6 for Database Connectivity

Code For Module.bas

Now we must add code so that our VB project can programmatically connect to the MS Access database.

Public con As New ADODB.Connection
Public rs As New ADODB.Recordset
Dim rsgrid As New ADODB.Recordset
Public constr As String
Public Sub loadcon()
constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\VBProjects\Attendance\attendance.mdb;Persist Security Info=False"
con.Open constr
MsgBox ("connected")
End Sub

The function loadcon() is called whenever database connectivity is required. All connections must be closed as soon as form unloads

Main Screen

The main screen is the first screen that a user is going to see. This section discusses the design of the Student Attendance Management System Using VB 6 Part 3 main splash screen.

Form Design (frmSpalsh)

The splash screen is a special screen. You can add a splash screen from Standard Toolbar > Form > under Add Form, select Add a Splash and modify the form according to your project.

Components for Main Screen

The splash screen comes with pre-configured labels. You need to modify them and add some new controls in this project. Here are the list of components.

Form Details

Name : frmSplash
Caption : Attendance Management System
BackColor : Window Text
ForeColor : Highlight Text

Frame Control

Now you need to add a frame control and right click and click “send to back”. Existing controls are not visible;therefore, delete them and create identical labels on top of frame control. If you wish, skip frame control and continue creating rest of the controls.

Code For Main Screen

Option Explicit
Public userlogin As Integer
Private Sub cmdAdmin_Click()
frmALogin.Show
End Sub
Private Sub cmdStu_Click()
frmLogin.Show
End Sub
Private Sub cmdTeach_Click()
frmTULogin.Show
End Sub
Private Sub Form_KeyPress(KeyAscii As Integer)
    Unload Me
    
End Sub
Private Sub Form_Load()
    lblVersion.Caption = "Version " & App.Major & "." & App.Minor & "." & App.Revision
    lblProductName.Caption = App.Title
        
End Sub
Private Sub Frame1_Click()
    Unload Me
End Sub

Note that above code may give error because login forms are not created yet. Continue to create login forms.

Student Login

System Diagram For Student Login

The student login has two inputs – user id and password.

The easiest way to create a login form is to click Standard toolbar on VB project editor and click Form > select Log in Dialog from Add Form Window. The login in dialog comes with a preexisting code which you can modify later. In this example project, we have used the login dialog.

Public LoginSucceeded As Boolean
Private Sub cmdCancel_Click()
 'set the global var to false ' to denote a failed login
 LoginSucceeded = False
 Me.Hide
 End Sub
 Private Sub cmdOK_Click()
 
 'making connection
  
 Call loadcon
  
rs.Open "SELECT * FROM Student ", con, adOpenDynamic, adLockReadOnly
While Not rs.EOF
 If rs!SID = Val(txtSID) Then
 'check for correct password
 If rs!Password = txtPassword Then
 frmSplash.userlogin = rs!SID
  'place code to here to pass the 'success to the calling sub 'setting a global var is the easiest LoginSucceeded = True
 frmMenu.Show
 Unload Me
  'closing connection and recordset
  rs.Close
  con.Close
  
 Exit Sub
 Else
 MsgBox "Invalid Password, try again!", , "Login"
 txtPassword.SetFocus
 SendKeys "{Home}+{End}"
 End If
 End If
 rs.MoveNext
 Wend
End Sub
 Private Sub Form_Load()
 frmSplash.Hide
 End Sub


Teacher Login

Code for Teacher Login

The code for teacher login is created by modifying the preexisting code of “login dialog” form.

Option Explicit
Public LoginSucceeded As Boolean
Private Sub cmdCancel_Click()
 'set the global var to false ' to denote a failed login
 LoginSucceeded = False
 Me.Hide
 End Sub
 Private Sub cmdOK_Click()
 
 'making connection
 Call loadcon
rs.Open "SELECT * FROM Teacher ", con, adOpenDynamic, adLockReadOnly
While Not rs.EOF
 If rs!tid = Val(txtTID) Then
 'check for correct password
 If rs!Password = txtPassword Then
 frmSplash.userlogin = rs!tid
 'place code to here to pass the 'success to the calling sub 'setting a global var is the easiest LoginSucceeded = True
 frmMenu.Show
 Unload Me
  'closing connection and recordset
  rs.Close
  con.Close
  
 Exit Sub
 Else
 MsgBox "Invalid Password, try again!", , "Login"
 txtPassword.SetFocus
 SendKeys "{Home}+{End}"
 End If
 End If
 rs.MoveNext
 Wend
End Sub
 Private Sub Form_Load()
 frmSplash.Hide
 End Sub
