Examples

Simple Usage

Dim myArray = Array(1, 2, 3, 4, 5)
For Each item In myArray
  WScript.Echo item
Next

Complex Usage

Set myCollection = CreateObject("Scripting.Dictionary")
myCollection.Add "Key1", "Value1"
myCollection.Add "Key2", "Value2"

For Each key In myCollection.Keys
  WScript.Echo key & ": " & myCollection(key)

Common Issues

• Ensure the iterable collection is valid and contains elements.
• Avoid modifying the collection within the loop as it can lead to unpredictable results.

Integration

For Each… is often used in conjunction with other VB Script commands, such as:

• WScript.Echo: To print loop results to the console.
• CreateObject: To create collection objects.
• If…Then…Else: To perform conditional actions based on loop elements.
