Variable Declaration

In VBA, variables are declared using the Dim statement, specifying the variable name and type. In Haskell, types are declared using the :: syntax.

VBA Example:

Dim x As Integer

Haskell Example:

x :: Int

References:

Control Structures

VBA uses If...Then...Else for conditional execution, while Haskell uses a more concise if...then syntax.

VBA Example:

If x > 10 Then
    ' Do something
End If

Haskell Example:

if x > 10 then
    -- Do something

Function Definition

In VBA, functions are defined with the Function keyword and specify return types. Haskell uses type signatures to define functions.

VBA Example:

Function Add(a As Integer, b As Integer) As Integer
    Add = a + b
End Function

Haskell Example:

add :: Int -> Int -> Int
add a b = a + b

Error Handling

VBA uses On Error statements for error handling, while Haskell employs try and catch for exception handling.

VBA Example:

On Error GoTo ErrorHandler

Haskell Example:

import Control.Exception (try, SomeException)

handleError :: IO ()
handleError = do
    result <- try (someIOAction) :: IO (Either SomeException ())
    case result of
        Left ex  -> putStrLn "Caught an exception!"
        Right _  -> return ()

References:

Object-Oriented Features

VBA supports object-oriented programming with classes and objects, while Haskell uses data types and type classes.

VBA Example:

Set obj = New ClassName

Haskell Example:

data ClassName = ClassName { field1 :: Type1, field2 :: Type2 }

References:

Collections and Arrays

VBA uses fixed-size arrays, while Haskell uses lists which are more flexible.

VBA Example:

Dim arr(1 To 10) As Integer

Haskell Example:

arr :: [Int]

References:

Type Conversion

VBA provides functions like CStr for type conversion, while Haskell uses functions like show.

VBA Example:

CStr(x)

Haskell Example:

show x

References:

String Manipulation

VBA has built-in functions like Mid for string manipulation, while Haskell uses list functions.

VBA Example:

Mid(str, 1, 5)

Haskell Example:

take 5 str

References:

Event Handling

VBA uses event-driven programming with event handlers, while Haskell uses a more functional approach to handle events.

VBA Example:

Private Sub Worksheet_Change()
    ' Handle change event
End Sub

Haskell Example:

onChange :: Event -> ...

References:

Built-in Functions

VBA has built-in functions like MsgBox, while Haskell uses putStrLn for output.

VBA Example:

MsgBox("Hello")

Haskell Example:

putStrLn "Hello"
