Syntax help

Variables

Variable is a name given to the storage area in order to identify them in our programs.

Simple syntax of Variable declaration is as follows

Dim variableName [ As [ New ] dataType ] [ = initializer ]

Variable initialization

variableName = value

Conditional Statements

1. If

If condition-expression Then 'code End If

2. If-else

If(conditional-expression)Then 'code if the conditional-expression is true Else 'code if the conditional-expression is false End If

3. If-else-if ladder

If(conditional-expression)Then 'code if the above conditional-expression is true Else If(conditional-expression) Then 'code if the above conditional-expression is true Else 'code if the above conditional-expression is false End If

4. Nested-If

If(conditional-expression)Then 'code if the above conditional-expression is true If(conditional-expression)Then 'code if the above conditional-expression is true End If End If

5. Select Case

Select [ Case ] expression [ Case expressionlist 'code ] [ Case Else 'code ] End Select

Loops

1. For..Next

For counter [ As datatype ] = begin To end [ Step step ] 'code [ Continue For ] 'code [ Exit For ] 'code Next [ counter ]

2. For..Each

For Each element [ As datatype ] In group 'code [ Continue For ] 'code [ Exit For ] 'code Next [ element ]

3. While

While conditional-expression 'Code [ Continue While ] 'Code [ Exit While ] 'Code End While

4. Do-while

Do { While | Until } conditional-expression 'Code [ Continue Do ] 'Code [ Exit Do ] 'Code Loop Do 'Code [ Continue Do ] 'Code [ Exit Do ] 'Code Loop { While | Until } conditional-expression

Procedures

Procedure is a sub-routine which contains set of statements. Usually Procedures are written when multiple calls are required to same set of statements which increases re-usuability and modularity.

Procedures are of two types.

1. Functions

Functions return a value when they are called.

[accessModifiers] Function functionName [(parameterList)] As returnType 'code End Function

2. Sub-Procedures

Sub-procedures are similar to functions but they don't return any value.

Sub ProcedureName (parameterList) 'Code End Sub
