Copying latest date from weekly workbook

[Meltad]

Hi everyone,
I'm trying to write a macro to copy data from one workbook to another. I
have opened the first workbook which has a weeks worth of dates and data, and
need to identify and copy the latest date on that workbook and paste into the
new workbook. The data is sorted by date so the latest date is always at the
bottom. Is there a way of selecting the rows for the most recent date only??
I hope someone can help me!
Thanks, Mel

Assuming the dates are in col A you could try some thing like:

Sub MoveData()
Dim wbk1 as Workbook
Dim wbk2 as Workbook
Dim Source as Range
Dim Dest as Range

Set wbk1 = ActiveWorkbook
Set Source = wbk1.Sheets(1).Range("A65536").End(xlUp).EntireRow

Set wbk2 = Workbooks("MyOtherBook")
Set Dest = wbk2.Sheets(1).Range("A65536").End(xlUp)

Source.Copy Dest


End Sub

Thanks,
My dates are in column C, so Inplayed around with your macro ( replaced 1
with 3) but wasn't sure how this was working. This is what I've got so far

Sub LFmacro()

Dim nRows As Long

ChDir "G:\Lou French macro"
Workbooks.Open Filename:="G:\Lou French macro\podnondel.CSV"

'copy latest date from podnondel workbook
'colour rows red

Windows("LFmacro.XLS").Activate
Range("A2").Select
ActiveSheet.Paste

End Sub

So I need to know how to slot your latest date part into the middle!! Would
this work or do I abandon my part and use all of yours??
Thanks

Sub LFmacro()

Dim nRows As Long

ChDir "G:\Lou French macro"
Workbooks.Open Filename:="G:\Lou French macro\podnondel.CSV"

'copy latest date from podnondel workbook
'colour rows red

nrows = Application.CountA(columns(3))
rows(nrows).copy
Windows("LFmacro.XLS").Activate
cells(rows.count,3).End(xlup).offset(1,-2).Select
ActiveSheet.Paste

End Sub

or

Sub LFmacro()

Dim wbk1 as Workbook
Dim wbk2 as Workbook
Dim Source as Range
Dim Dest as Range

Set wbk2 = Workbooks("LFmacro.XLS")
Set Dest = wbk1.Worksheets(1).Cells(rows.count,3).End(xlUp)(2).EntireRow

ChDir "G:\Lou French macro"
Set wbk1=Workbooks.Open( Filename:="G:\Lou French macro\podnondel.CSV")
Set Source = wbk1.Worksheets(1).Cells(rows.count,3).End(xlup).EntireRow
'copy latest date from podnondel workbook
'colour rows red

Source.Copy Dest
End Sub


Change Worksheets(1) to reference the proper sheet in LFmacro.xls

This is great thanks Tom but I need to copy over all rows with that date not
just the one. How can I amend the code to pick up all instances of the most
recent date?

Sub LFmacro()

Dim wbk1 as Workbook
Dim wbk2 as Workbook
Dim Source as Range
Dim Dest as Range
Dim i as Long

Set wbk2 = Workbooks("LFmacro.XLS")
Set Dest = wbk1.Worksheets(1).Cells(rows.count,3).End(xlUp)(2).EntireRow

ChDir "G:\Lou French macro"
Set wbk1=Workbooks.Open( Filename:="G:\Lou French macro\podnondel.CSV")
Set Source = wbk1.Worksheets(1).Cells(rows.count,3).End(xlup).EntireRow
i = -1
do while source.offset(i,0).Value = source
i = i + 1
Loop
set source = source.offset(i + 1,0).Resize(-i).EntireRow
Source.Copy Dest
End Sub

Hi Tom,
Thanks for that, I tried to run it but got an error on this line:

"Run time error 92, object variable or With block variable not set"

Set Dest = wbk1.Worksheets(1).Cells(Rows.Count, 3).End(xlUp)(2).EntireRow

Not sure what I've missed...

 

[cush]

I think Tom meant wbk2:

Set Dest = wbk2.Worksheets(1).Cells(Rows.Count, 3).End(xlUp)(2).EntireRow

 

[Tom Ogilvy]

That line hasn't changed and you said it worked in the previous version of
the macro.

demo't from the immediate window:

set dest = wbk1.Worksheets(1).Cells(rows.count,3).End(xlup).EntireRow
? dest.Address
$90:$90

Sorry about this Tom,
On your earlier post you gave 2 examples of codes to use to copy the latest
date, I used the top one (this worked for one line only) - the second one you
posted containing this line where I get the error but doesn't work for me. I
changed to wbk1 to wbk2 as cush suggested but still get an error on another
line a bit further down:
Do While Source.Offset(i, 0).Value = Source
(application defined or object defined error??)
??

Sub LFmacro()

Dim nRows As Long
Dim i as Long
Dim Source as Range

ChDir "G:\Lou French macro"
Workbooks.Open Filename:="G:\Lou French macro\podnondel.CSV"

'copy latest date from podnondel workbook
'colour rows red

nrows = Application.CountA(Columns(3))
i = 1
Do While Cells(nrows, 3).Offset(-i, 0).Value = Cells(nrows, 3).Value
i = i + 1
Loop
Set Source = Cells(nrows, 3).Offset(-1 * (i - 1), 0).Resize(i).EntireRow
Source.Copy
Windows("LFmacro.XLS").Activate
cells(rows.count,3).End(xlup).offset(1,-2).Select
ActiveSheet.Paste

End Sub

Hi Tom,
Thanks again! This code works through with no errors but the loop part
doesn't seem to do what I expected... I still only get 1 row pasted across to
the new workbook - it doesn't pick up all instances of that date. Also please
can you explain how this is supposed to work? I can't understand how it will
select that latest date only?? Thank you, sorry to be a pain!

It finds the last date by counting the number of entries.

nrows = Application.CountA(Columns(3))

assumes the latest date is the last date.
