Private Sub Command1_Click()
    Text3.Text = Val(Text1.Text) + Val(Text2.Text)
End Sub
    

1. What is Visual Basic 6.0 Calculator Code?

This is a simple addition calculator implemented in Visual Basic 6.0. The code demonstrates basic form handling and arithmetic operations in the VB6 environment.

2. How Does the Calculator Work?

The calculator uses the following VB6 code:

Private Sub Command1_Click()
    Text3.Text = Val(Text1.Text) + Val(Text2.Text)
End Sub
                    

Where:

• Text1.Text — First input number
• Text2.Text — Second input number
• Text3.Text — Result of the addition
• Val() — Function to convert text to numeric value

Explanation: When the command button is clicked, the values from Text1 and Text2 are converted to numbers and added together, with the result displayed in Text3.

3. Importance of Calculator Code

Details: This simple example demonstrates fundamental concepts in VB6 programming including event handling, type conversion, and basic arithmetic operations.

4. Using the Calculator

Tips: Enter two numbers in the input fields and click Calculate to see the sum. This simulates the behavior of the VB6 calculator code.

5. Frequently Asked Questions (FAQ)

Q1: What is Visual Basic 6.0?
A: VB6 is an event-driven programming language and integrated development environment (IDE) from Microsoft, released in 1998.

Q2: How does Val() function work?
A: Val() converts a string to a number by reading until it encounters a non-numeric character, then returns the numeric portion.

Q3: What are the limitations of this code?
A: It doesn't include error handling for non-numeric inputs or overflow conditions.

Q4: Can this be extended for other operations?
A: Yes, you could add buttons for subtraction, multiplication, and division with similar code patterns.

Q5: Is VB6 still used today?
A: While largely replaced by newer technologies, some legacy systems still use VB6 applications.
