Question

I have an array like this:

Dim aFirstArray() As Variant

How do I clear the entire array?
What about a collection?

Answer 1

You can either use the Erase or ReDim statements to clear the array. Examples of each are shown in the MSDN documentation. For example:

Dim threeDimArray(9, 9, 9), twoDimArray(9, 9) As Integer
Erase threeDimArray, twoDimArray
ReDim threeDimArray(4, 4, 9)

To remove a collection, you iterate over its items and use the Remove method:

For i = 1 to MyCollection.Count
  MyCollection.Remove 1 ' Remove first item
Next i
