A piece of code I came up with whilst trying to solve a post at vbCity was what I term Combine. It basically does the opposite of Split and creates a string out of a single dimensional array.
Private Function Combine(ByVal oVvArray As Variant _
, ByVal strVvDelimiter As String _
) As String
Dim intLvIndex As Integer
For intLvIndex = LBound(oVvArray) To UBound(oVvArray)
Combine = Combine & CStr(oVvArray(intLvIndex)) & strVvDelimiter
Next
Combine = IIf(Right$(Combine, Len(strVvDelimiter)) = strVvDelimiter _
, Left$(Combine, Len(Combine) - Len(strVvDelimiter)) _
, Combine _
)
End Function
