Excel Deletes Top to bottom
 

Hi Guys, I am trying to delete all the rows preceeding the FIRST ro
that has 'o1CR' in the first 4 bytes of col 'A'. The very first ro
contains a hdr with the literal "AccountNumber" in cell A1.

I have managed to locate the 01CR rec and realize the correct ro
number to start my deletes moving from bottom (the 01CR rec ) to th
top (which I am told is the best way to delete in Excel).

However I have not been successful in assigning the row that proced
the 01CR row as the LastRow. Does anyone know how I do that?

Here is my code. I know there are better techniques but Excel is not m
first language.

Sub CleanUp_File_2()
Dim i As Integer
Dim MaxElements As Integer
Dim cnt As Integer
Dim LeftValue As String
Dim HDR As Range
Dim row1 As Variant

LeftValue = ""
cnt = 0
MaxElements = 7000
ActiveCell.Range("A2").Select

For i = 1 To MaxElements
LeftValue = Left(Cells(i, 1), 11)
If Left(Cells(i, 1), 4) = "01CR" Then
Exit For
Else
cnt = cnt + 1
End If

If cnt = 4379 Then
Stop
End If

Next i

Range("A2").Select
ActiveCell.FormulaR1C1 = "HDR"

Dim LastRow As Range
cnt = cnt - 1
row1 = ("A" & cnt)

LastRow = Worksheets("sheet1").Cells(cnt, 0)
For i = LastRow To HDR Step 1 - 1
If Cells(i, 0) = "AccountNumber" Then
Else
Rows(i).Delete
End If
Next i

End Sub

The error msg appication defines or object defined error becaus
.Cells(cnt, 0)
is invalid. How can I fix this

Excel Deletes Top to bottom
 

So you want to keep row 1 and delete rows 2 to the first cell that contains 01CR
as the first 4 characters, but keep that 01CR row?

Option Explicit
Sub testme()
Dim FoundCell As Range
Dim WhatToFind As String

WhatToFind = "01CR*"

With Worksheets("sheet1")
With .Range("a:a")
Set FoundCell = .Cells.Find(what:=WhatToFind, _
after:=.Cells(.Cells.Count), _
LookIn:=xlValues, _
lookat:=xlWhole, _
searchorder:=xlByRows, _
searchdirection:=xlNext, _
MatchCase:=False)

If FoundCell Is Nothing Then
MsgBox WhatToFind & " wasn't found"
Else
If FoundCell.Row < 3 Then
'do nothing, it's already cleaned up
Else
.Range("a2:A" & FoundCell.Row - 1).EntireRow.Delete
End If
End If
End With
End With

End Sub


It's essentially going to the bottom of column A and doing Edit|find and looking
for the topmost cell with 01CR in it.

Then deleting all the rows from 2 to the one above it.

The error msg appication defines or object defined error because

Excel Deletes Top to bottom
 

Just wanted to offer one or two pointers on your code (for future reference -
my solution is similar to Dave's so I won't repeat what's already done)

LastRow = Worksheets("sheet1").Cells(cnt, 0)

won't work because there is no column 0. Also, you declared Lastrow as a
range, so you must use a Set statement.

Set LastRow = Worksheets("sheet1").Cells(cnt, 1)

Once you know the first and last rows you can delete the entire range
without looping backwards (which I personally hate because it is much slower
to delete one row at a time).

One last thing - I wasn't clear on if you wanted to delete the entire row or
not. If you don't you should be able to change this line in Dave's macro
from:

..Range("a2:A" & FoundCell.Row - 1).EntireRow.Delete

To

..Range("a2:A" & FoundCell.Row - 1).Rows.Delete (xlup)
