Macro for hiding rows

Hi K,

1) I guess the task is to hide not to delete

Thank you - yes I mis-read!

so probably:
Columns(2).SpecialCells(xlCellTypeBlanks).EntireRo w.Hidden=True

With the qualification of my follow-up post that columns(2) should read
Columns(1), for obvious reasons.

2) This method has a limitation of max 8,192 non-contiguous cells

I am aware of the problem and have frequently referred to this in other
posts.

It should be noted, however, that the constraining factor is independent of
the number of blank cells. To demonstrate this try:

'=============
Public Sub Demo()
Dim i As Long
Dim rng As Range, rng1 As Range

Application.ScreenUpdating = False

Set rng = Range("A1").Resize(8192 * 3 - 2)

rng.Value = "XYZ"

For i = 1 To rng.Count Step 3
Cells(i, 1).Resize(2).Clear
Next i

Set rng1 = rng.SpecialCells(xlCellTypeBlanks)

rng1.Interior.ColorIndex = 6

Debug.Print "rng1.Cells.Count ", rng1.Cells.Count
Debug.Print "rng1.Areas.Count ", rng1.Areas.Count

Application.ScreenUpdating = True

End Sub
'=============

just to add two comments:

1) I guess the task is to hide not to delete, so probably:
Columns(2).SpecialCells(xlCellTypeBlanks).EntireRo w.Hidden=True

2) This method has a limitation of max 8,192 non-contiguous cells
(otherwise it includes the whole column/row/sheet):
http://support.microsoft.com/kb/832293/en-us For this to become an issue
in this specific example one needs to have at least 16385 rows where every
other row is blank (so the risk might be remote).

Hi Luke,

As an alternative, try:

Try:

'=============
Public Sub Tester()

On Error Resume Next
Columns(2).SpecialCells(xlCellTypeBlanks).EntireRo w.Delete
On Error GoTo 0

End Sub
'=============

I have a spreadsheet which contains a lot of rows with no data, I would
like
to create a macro to hide these rows.

Preferably I would like it to work off one column and hide any rows with
a
value of zero.

Any ideas?

Let's back up here.
If a cell has a 0 (zero) in it, it is not blank.

It looks like all or most of the suggestions offered here
has been if cells are Blank. But, I see that you "prefer"
if rows are 0 (zero value).

Before running this macro select (highlight) your intended range, say G2:G1000
Using Selection make the macro a bit more useful.

In a standard module put:

Sub HideRowsWithZero
For Each c In Selection
If c.Value = 0 Then
c.EntireRow.Hidden = True
End If
Next c
End Sub


Hope that Helps,

another way without macros:

1) select one of the columns where empty cells correspond to empty rows
2) menu EditGoto... 3) press the button 'Special...'
4) mark the 'Blanks' option and press 'OK'
5) menu FormatRowsHide...

or using short cut keys:

1) having the cursor in a cell of the relevant column press Ctrl+Space
2) Ctrl+g
3) Hold Alt+ s, k, 4) Enter
5) Hold Alt + o, r, h

Hi Jim,

Granted that there is potential ambiguity, my response was predicated on the
OP's statement:

I have a spreadsheet which contains a lot of rows with no data.

Which interpretation is correct can only be resolved by the OP, but at least
he now has solutions to deal with either eventuality.

Hi Norman,

It should be noted, however, that the constraining factor is independent of the number of blank cells. To demonstrate this try:

Oh yes it is, but not only of the number of blank cells but the way they are distributed. As I said in my previous message "for this
to become an issue in this specific example one needs to have at least 16385 rows where every other row is blank..." In other words
there need to be more than 8192 areas. Your code returns exactly 8192 areas, so try this one (and if you still believe that it is
independent of the # of blank cells, try reproducing the problem with =8192 blank cells):

Public Sub Demo()
Dim i As Long
Dim rng As Range, rng1 As Range

Application.ScreenUpdating = False
Set rng = Range("A1").Resize(8192 * 3 - 1)
rng.Value = "XYZ"
For i = 1 To rng.Count Step 3
Cells(i, 1).Resize(2).Clear
Next i
Set rng1 = rng.SpecialCells(xlCellTypeBlanks)
MsgBox rng1.Areas.Count
Application.ScreenUpdating = True
Exit Sub
End Sub

Hi K,

I suspect that you misunderstand both my statement and the purpose of my
post, which had no polemical intent,.

I am well aware of the distinction between areas and cells and the relevance
of these to the use of the SpecialCells method. As I indicated, I have
referred to this precise issue in numerous previous posts,

My response, which was primarily aimed at the OP, was intended to indicate
that the number of blank cells was not a limiting issue.

I was concerned that your use of the expression:

This method has a limitation of max 8,192 non-contiguous cells

without any reference to areas or ranges might be interpreted as indicating
a limit to the number of blank cells.

This concern was not alleviated by your subsequent statement:

For this to become an issue in this specific example one needs to have at
least 16385 rows where every other row is blank (so the risk might be
remote).

which, as it implicitly refers to 8192 blank cells, might, I felt, serve to
reinforce any misconception.

I therefore provided an example of a viable use of the SpecialCells method
in which the range of interest comprised over 16k blank cells. Obviously,
the example could readily be adapted to produce analogous results with much
higher numbers of blank cells. The question of the number of areas was not
an issue: indeed the only reference to areas and, implicitly, their
relevance, was in my post. It was, as I have indicated, this contextual
omission which prompted my response.

OK let's attribute this to my poor command of English, but just for clarity "This method has a limitation of max 8,192
non-contiguous cells" is not mine but rather Microsoft's :-) English isn't my native language, so I am sure you can explain to me
how can "8,192 non-contiguous cells" mean anything different to "8,192 areas" in Excel.

Hi KL,

My interest was not a matter of semantics but uniquely the question of
possible (mis)interpretation: the mere fact that cell and area may be
interpreted differently might have some bearing.

Before leaving this matter, I note that I have omitted to respond to your
challenge:

Your code returns exactly 8192 areas, so try this one (and if you still
believe that it is independent of the # of blank cells, try reproducing
the problem with =8192 blank cells):

Let me, therefore, rectify: try this version of the previously suggested
code:

'=============
Public Sub Demo2()
Dim i As Long
Dim rng As Range, rng1 As Range, rng2 As Range

Application.ScreenUpdating = False

Set rng = Range("A1:A16384")

rng.Value = "XYZ"

For i = 1 To rng.Rows.Count Step 2
rng.Rows(i).Clear
Next i

Set rng1 = rng.SpecialCells(xlCellTypeBlanks)
Set rng2 = rng.Columns(1).SpecialCells(xlCellTypeBlanks)

MsgBox "Rng1 Areas =" & rng1.Areas.Count _
& vbNewLine & _
"Rng2 Areas =" & rng2.Areas.Count

Application.ScreenUpdating = True

End Sub
'=============

Hi KL,

A significant typo:

Set rng = Range("A1:A16384")

should read:

Set rng = Range("A1:B16384")

Norman,

It is an interesting paradox, but strictly speaking the challenge was to make SpecialCells fail with =8192 blank cells. I think
there were 16384 blank cells in the range where SpecialCells failed. Anyway, do you know why this happens?

Thanks and regards,
KL

From the context of the thread and all preceding references, I took this to
mean non-contiguous cells! g

As for the paradox, I noted in the past that it is possible to provoke the
solid range syndrome at points below 8192 non-contiguous areas. See, for
example:
