Is it possible to fill an array with row numbers which match a certain criteria without looping?

Question

I would like to fill an array in VBA with the row numbers of only rows which meet a certain criteria. I would like the fastest method possible (for example, something like <

Answer 1

I still have a loop, but only through the necessary rows to populate the array:

Sub get_row_numbers()

Dim RowArray() As Long
Dim valRange As Range
Dim valMatch As String

Set valRange = ActiveSheet.Range("A1:A11")
valMatch = "aa"
ReDim RowArray(WorksheetFunction.CountIf(valRange, valMatch) - 1)

Dim c As Range
Dim x As Integer
Set c = valRange.Find(What:=valMatch, LookIn:=xlFormulas, SearchOrder:=xlByRows, SearchDirection:=xlNext)

Do
  RowArray(x) = c.Row
  Set c = valRange.FindNext(after:=c)
  x = x + 1
Loop Until x = UBound(RowArray) + 1


End Sub
