Programming in VB.NET — Lesson 1: VB.NET Language and Programming Foundations

Learning Objectives

• Create projects and use variables, data types, operators, expressions, and conversion
• Apply If, Select Case, loops, procedures, functions, arrays, and strings
• Debug syntax, logic, null, conversion, and boundary errors

Detailed Topics

• Create projects and use variables: Create projects and use variables, data types, operators, expressions, and conversion
• Apply If: Apply If, Select Case, loops, procedures, functions, arrays, and strings
• Debug syntax: Debug syntax, logic, null, conversion, and boundary errors

Guided Demonstration

1. Review the requirement, environment, dependencies, roles, risks, and expected outcome.
2. Demonstrate the relevant configuration, analysis, code, or administration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, or test evidence.
4. Compare the observed result with the stated acceptance criteria.

Hands-On Activity

Build a validated VB.NET program that processes business input.

• Document assumptions and the planned sequence before making changes.
• Complete the activity and preserve evidence of normal and exception behavior.
• Record issues, corrective actions, and reusable operational or development notes.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, permissions, data, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, support ownership, and user or business impact.

Validation Checklist

• The requirement and expected outcome are clear.
• The selected configuration, design, query, code, or process is documented.
• Normal, boundary, failure, security, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply VB.NET Language and Programming Foundations in a realistic scenario and validate the result with documented evidence.
