Form Designer

• Forms is a useful place to assemble all controls.

Code Editor

• Every form has a Code Editor for code writing, such as double-clicking.

Properties Window

• You can set or read all Form properties using Properties Window.

VB.NET Data Types

• DATATYPE in any programming language shows the type of data a variable can hold or the data type a variable belongs to.
• Syntax: Dim VariableName as DataType.

Datatypes commonly used:

• Boolean
• Integer
• String

Types of Conversion

• Implicit Type Conversions means the computer will automatically convert for you.
• Explicit Type Conversions when the compiler does not automatically convert a type, needing a type conversion keyword.

VB.NET Access Specifiers

• Access Specifiers describes the scope of accessibility of an Object.

The five Access Specifiers are:

• Public: Can accessed by all.
• Private: Can be accessed only by class.
• Protected: Only from class and inherited classes.
• Friend: Is is like public but only accessed by the project.
• ProtectedFriend: Combination of Protected and Friend.

Conditional statements

• Examine the stated condition statement for any possible decision. If [your condition here] Then.

FOR NEXT Loop
