AutoFilter Confusion (no records found)

[Bigfoot17]

I am having soem problems figuring out how to tackle a problem. I have been
successful in [1] autofiltering a spreadsheet; [2] selecting the filtered
data and [3] copying it to a new sheet where I further manipulate it.

However, I have found that when my autofilter finds no appropriate data (no
record between two dates) instead of getting zero records I instead get all
of the data copied.

Can someone shed light on this and point me in the proper direction? Here
is part of my selection and copy process:
dLrow = Cells(Rows.Count, "P").End(xlUp).Row
'Field:=16 is Column P(card expiration date), D(last name, C(first name)
Selection.AutoFilter Field:=16, Criteria1:=">=" & startFilter,
Operator:=xlAnd _
, Criteria2:="<" & endFilter
Range("D3" & dLrow & ",E3:E" & dLrow & ",P3" & dLrow).Select
Selection.Copy
Workbooks.Add
Range("A2").Select
ActiveSheet.Paste

If those values in column P are really dates...

Search for "Range.AutoFilter" and you'll see this note:

Range.AutoFilter

The AutoFilter method of a Range object is a very curious beast. We are forced
to pass it strings for its filter criteria and hence must be aware of its string
handling behaviour. The criteria string consists of an operator (=, >, <, >=
etc.) followed by a value.

If no operator is specified, the "=" operator is assumed. The key issue is that
when using the "=" operator, AutoFilter performs a textual match, while using
any other operator results in a match by value. This gives us problems when
trying to locate exact matches for dates and numbers.

If we use "=", Excel matches on the text that is displayed in the cell, i.e. the
formatted number. As the text displayed in a cell will change with different
regional settings and Windows language version, it is impossible for us to
create a criteria string that will locate an exact match in all locales.

There is a workaround for this problem. When using any of the other filter
criteria, Excel plays by the rules and interprets the criteria string according
to US formats. Hence, a search criterion of ">=02/01/2001" will find all dates
on or after 1st Feb, 2001, in all locales.

We can use this to match an exact date by using two AutoFilter criteria. The
following code will give an exact match on 1st Feb, 2001 and will work in any
locale:

Range("A1200").AutoFilter 2, ">=02/01/2001", xlAnd, "<=02/01/2001"

So you may want (guessing because you didn't share what startfilter and
endfilter were):

Selection.AutoFilter Field:=16, _
Criteria1:=">=" & format(startFilter, "mm/dd/yyyy")
Operator:=xlAnd, _
Criteria2:="<" & format(endFilter, "mm/dd/yyyy")

Your right I should have probably included what startFilter and endFilter
were, and now I can't as I am at a different location. However, I have set
startFilter and endFilter as dates earlier (hmm... perhaps they are strings,
I better check). Anyway I am successful in getting the filtered records that
fall between my dates with "Range("D3" & dLrow & ",E3:E" & dLrow & ",P3"
& dLrow).Select" BUT my issue is that if there are not records between the
dates then "Range("D3" & dLrow & ",E3:E" & dLrow & ",P3" & dLrow).Select"
gives me all of the records.

Thank you for the time you took to research this.

I'm not sure what range you're filtering (Selection doesn't help if you don't
share what the selection is).

But if you can pick out the last used row by column P (or anything column) and
the last used column by using row 2 (some kind of titles in row 1??? and field
headers in row 2), then maybe this will help.

It filters and copy of the data rows (avoiding the field headers) to a new sheet
in a new workbook:

Option Explicit
Sub testme()

Dim wks As Worksheet
Dim myRng As Range
Dim VisRng As Range
Dim LastRow As Long
Dim LastCol As Long
Dim StartFilter As Date
Dim EndFilter As Date
Dim NewWks As Worksheet
Dim ColsToCopy As Variant
Dim iCol As Long
Dim DestCell As Range

Set wks = Worksheets("sheet1")
StartFilter = DateSerial(2009, 4, 25)
EndFilter = DateSerial(2009, 5, 1)
ColsToCopy = Array("D", "E", "P")

With wks
'remove the existing filter
.AutoFilterMode = False

LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
LastCol = .Cells(2, .Columns.Count).End(xlToLeft).Column

If LastCol < .Range("P1").Column Then
MsgBox "Not enough columns!"
Exit Sub
End If

'titles in Row 1. Field headers in row 2
Set myRng = .Range("a2", .Cells(LastRow, LastCol))

With myRng
.AutoFilter Field:=16, _
Criteria1:=">=" & Format(StartFilter, "mm/dd/yyyy"), _
Operator:=xlAnd, _
Criteria2:="<" & Format(EndFilter, "mm/dd/yyyy")

If .Columns(1).Cells.SpecialCells(xlCellTypeVisible).Count = 1 Then
'nothing visible
Set VisRng = Nothing
Else
Set NewWks = Workbooks.Add(1).Worksheets(1)
Set DestCell = NewWks.Range("a1")

'come down 1 row to avoid headers
'resize by -1 to avoid extra row at bottom
Set VisRng = .Resize(.Rows.Count - 1).Offset(1, 0) _
.Cells.SpecialCells(xlCellTypeVisible)

For iCol = LBound(ColsToCopy) To UBound(ColsToCopy)
Intersect(VisRng, _
.Parent.Cells(1, ColsToCopy(iCol)).EntireColumn).Copy _
Destination:=DestCell
Set DestCell = DestCell.Offset(0, 1)
Next iCol
End If
End With
'remove the filter
.AutoFilterMode = False
End With

With NewWks
.UsedRange.Columns.AutoFit
End With
End Sub

Your right I should have probably included what startFilter and endFilter
were, and now I can't as I am at a different location. However, I have set
startFilter and endFilter as dates earlier (hmm... perhaps they are strings,
