Enumerate Collections With For Each...Next


It's faster to enumerate a collection with the For each...Next statetment:
 
Dim c As Class1
    For Each c In Col
        'Code...
    Next

Dim fldField As ADODB.Field
    For Each fldField In rsTemp
        'Code...
    Next

Dim LI As ListItem
    For Each LI In ListView1.ListItems
        'Code...
    Next

To find out the index while enumerating, use a variable:
 
Dim c As Class1
Dim Index as long
    For Each c In Col
        Index= Index + 1
        'Code...
    Next

Or, for zero based collections:
 
Dim c As Class1
Dim Index as long
    For Each c In Col
        'Code...
        Index= Index + 1
    Next
