manipulating results of autofilter in vba

[bst]

i'm working on an inventory tracking sheet that has a snapshot of data
for the current week and the week before. it tracks changes in inventory
assignment. i have already built an array that has each unique id for
the inventory that is being tracked. i then want to loop the array
applying an autofilter on the sheet with the criteria based on the array
data. the result of the autofilter (not counting the header) either 1
row (the item has been removed from inventory) or two rows (the data is
still in inventory, need to check if it has been reassigned).

my problem is that i can't seem to test for how many rows resulted in
the autofilter.

what i have so far:
for xCtr = 1 to totalSerials
ActiveSheet.UsedRange.Select
Selection.AutoFilter field:=2, Criteria1:=uniqueSerials(xCtr)
Set filteredRange = selection.SpecialCells(xlCellTypeVisible)

if filteredRange.rows.count = 1 then
filteredRange.cells(2,colException).value = "x"
'row 2 because the first row is the header
end if
if filteredRange.rows.count = 2 then
if filteredRange.cells(2,colName).value <> _
filteredRange.cells(3, colName).value then
filteredRange.cells(2, colException).value = "x"
filteredRange.cells(3, colException).value = "x"
end if
end if
selection.autofilter
next xCtr

then i'll sort the sheet based on the exception column

the first time the macro is ran it works fine, afterwards
filteredRange.rows.count returns 1 everytime. i get the same results
with filteredRange.specialcells(xlCellTypeVisible).count
i have tried assigning filteredRange different ways as well with the
same results.

do i even need filteredRange? if not how should i proceed? if so, how
can i get it to work as desired? i've read about 10 pages of google
searching autofilter in the newsgroup and can't seem to find what i
need. copying the rows to another sheet would make the macro run too
long and is not desired since i want to sort the results of the
conditionals above.

TIA

Try this:

Option Explicit
Sub testme01()
Dim myRng As Range
Set myRng = ActiveSheet.Range("a1,a3").EntireRow
MsgBox myRng.Address & vbLf & myRng.Rows.Count

Set myRng = ActiveSheet.Range("a1:a5,a7").EntireRow
MsgBox myRng.Address & vbLf & myRng.Rows.Count
End Sub

You'll see that the .rows.count returns the number of rows in the first
area--not the number of rows in the entire range.

Instead, you can look at a single column in that autofiltered range and count
the number of visible cells.

If that number is 1, then only the headers are visible (no real data).

If you want the number of rows that are visible (not counting the header), just
subtract 1 from the quantity of visible cells in that column.

Dim vRng as range
dim vRows as long
with worksheets("Sheet999").autofilter.range
set vrng = .columns(1).cells.specialcells(xlcelltypevisible)
vrows = vrng.cells.count - 1
select case vrows
case is = 0 'shouldn't happen in your case!
case is = 1
'what should happen here
case is = 2
'what should happen here
case is > 2
msgbox "oh, oh!"
end select
end with

Hi Dave,
the second option does not seem to work.
the first with line fails, nor does it allow me to set the autofilter
criteria. i believe you are leading me in the right direction, but it seems
as if i need more detail. i will continue to follow this lead. if you or
anyone else seems to have any more insight it would be greatly appreciated.
i'm using excel 2003 if that matters.

i'm now trying:
..Range("B1").AutoFilter field:=2, Criteria1:=uniqueSerials(xCtr)
Set filteredRange = .Cells.SpecialCells(xlCellTypeVisible)

i will attempt you column method, but i wonder if it will set my range to
just the column filtered, when i infact want to examine manipulate other
column's data. from more results i've examined, it is the set filteredRange
line that is working incorectly.

thanks
bst

The code I suggested is after the range has had the autofilter arrows applied.

And most likely after you've filtered by your criteria.

It was in addition to your filtering code--not a replacement for that portion.

well i have made some progress. i can now get an accurate count of the
visible cells with the following
turn on filter, and filter
set filteredRange = ActiveSheet.AutoFilter.Range
filteredRange.columns(1).specialCells(xlcelltypeVisible).count 'now
returns an accurate number of visible rows.

now my problem is that i can't figure out a way to access the data in
the filtered range. i must not understand the range ojbect very well,
but i would i think that with the filteredRange assignment that
filteredRange.cells(2,2) or filteredRange.cells(3,2) would give me the
visible cells which could be really (22,2) and (790,2), except it gives
me the literal cell value as if the sheet was not filtered. i also tried
filteredRange.specialcells(xlcelltypevisible).cells(3,2), yet with the
same results.

any ideas on how to access the data only in the visible without copying
it.

thanks for you help so far

dim vRng as range
dim myCell as range

with activesheet.autofilter.range
'this returns the first cell in each row that's visible
'by using offset(1,0), we're ignoring the first/header row
'by using .resize(), we're making sure that we get the correct
'rows--(Header - 1 number of rows).
set vRng = .columns(1).resize(.rows.count - 1,1).offset(1,0) _
.cells.specialcells(xlcelltypevisible)
end with

for each mycell in vrng.cells
'I don't know what you want to do when you access these
mycell.offset(0,1).value = "This is visible!"
next mycell

Dave,
I got side tracked with some other projects. your method below
worked as expected, but not as i needed. i eventually found the solution
to my problem my using the areas property(collection?) of the range
object. below is my solution. there is probably a more elegant way to do
this, but it works . Thanks for your help and time.

‎ For xCtr = 1 To totalSerials
'set the filter, count how many visible rows there are. set range
to just visible rows
.Range("B1").AutoFilter field:=2, Criteria1:=uniqueSerials(xCtr)
Set filteredRange = ActiveSheet.AutoFilter.Range
filteredRowCtr = filteredRange.Columns(1).SpecialCells
(xlCellTypeVisible).Count - 1
Set filteredRange = ActiveSheet.AutoFilter.Range.Offset(1,
0).SpecialCells(xlCellTypeVisible)

With filteredRange
'.Copy Destination:=Worksheets("Sheet2").Range("A1")
'if only one row then the scanner was sent back to corp or is new
from corp
'need to confirm what happened with terminal
If filteredRowCtr = 1 Then
' MsgBox (xCtr)
.Areas(1).Cells(1, colException).Value = "x"
End If

'if there are two scanners need to check if the status changed or
the owner changed
'if so then to follow up with terminal to confirm
If filteredRowCtr = 2 Then
'check status
If UCase(.Areas(1).Cells(1, colStatus).Value) <> _
UCase(.Areas(2).Cells(1, colStatus).Value) Then
'MsgBox (xCtr)
.Areas(1).Cells(1, colException).Value = "x"
.Areas(2).Cells(1, colException).Value = "x"
End If
'check owner
If UCase(.Areas(1).Cells(1, colName).Value) <> _
UCase(.Areas(2).Cells(1, colName).Value) Then
' MsgBox (xCtr)
.Areas(1).Cells(1, colException).Value = "x"
.Areas(2).Cells(1, colException).Value = "x"
End If
End If

'if there are more than 2 rows exit the script, something is wrong
If filteredRowCtr > 2 Then
MsgBox ("filtered row count is " & filteredRowCtr & ". xCtr
is " & xCtr)
End If

End With

'turn off autofilter
Worksheets("Sheet1").AutoFilterMode = False
Next xCtr
