Objective of the VB.NET Lab

The primary objectives of these lab exercises are to enable students to:

1. Understand the Visual Studio Integrated Development Environment (IDE).
2. Implement event-driven programming using Windows Forms controls.
3. Master control structures, arrays, procedures, and functions.
4. Apply object-oriented concepts like classes, inheritance, and polymorphism.

Program 5: Class and Object – Bank Account Management

Objective: Create a BankAccount class with data members (AccountNumber, CustomerName, Balance), methods (Deposit, Withdraw, DisplayBalance). Instantiate the class from a Windows Form.

Class Definition:

Public Class BankAccount
    Private _balance As Double
    Public Property AccountNumber As String
    Public Property CustomerName As String
    Public ReadOnly Property Balance As Double
        Get
            Return _balance
        End Get
    End Property
Public Sub Deposit(amount As Double)
    If amount > 0 Then _balance += amount
End Sub
Public Function Withdraw(amount As Double) As Boolean
    If amount > 0 AndAlso amount <= _balance Then
        _balance -= amount
        Return True
    Else
        Return False
    End If
End Function

End Class

Learning Outcome: Encapsulation, properties, methods, and object instantiation.

Part 7: The Ultimate Debugging Checklist for BCA Lab Exams

Before you raise your hand to show the output, run through this checklist: Objective of the VB

• [ ] Syntax Check: Are all End If, Next, Loop keywords matched?
• [ ] Variable Scope: Is the variable declared inside the correct event/subroutine?
• [ ] Option Strict: If Option Strict On is set, you cannot add an Integer to a String. Use CInt() or Convert.ToInt32().
• [ ] Infinite Loop: Does your While loop have an exit condition? (Press Ctrl + Break to stop execution if stuck).
• [ ] Design-time vs Run-time: Did you double-click the wrong button and put code in Form_Load instead of Button1_Click?
