Default Formulas containing hard coded values

Actually, the function I posted has a flaw in it... if you have a cell
address with 2 or more digits in its row number, the function will always
return True for that formula even if there is no numeric or text constants
in it. Here is a modified function which I believe works correctly in all
circumstances...

Function IsRefOnly(R As Range) As Boolean
Dim X As Long, Rw As Long
Dim Rng As Range, Cel As Range
Dim Fml As String, LCtext As String
Dim UCtext As String, OriginalFormula As String
If R.Count 1 Then
Err.Raise vbObjectError + 1001, "IsRefOnly Function", _
"Only one cell permitted in Range for this function!"
Exit Function
End If
OriginalFormula = R.Formula
R.Formula = LCase(R.Formula)
LCtext = R.Formula
R.Formula = UCase(R.Formula)
UCtext = R.Formula
R.Formula = OriginalFormula
If LCtext = UCtext Then
Fml = R.Formula
For Each Rng In R.Precedents.Areas
For Each Cel In Rng
Fml = Replace(Fml, Cel.Row, "")
Next
Next
If Not Fml Like "*#*" Then IsRefOnly = True
End If
End Function

My suggestion in my parallel post for you to use these immediately before
your loop through the range returned by the SpecialCells property ...

Application.EnableEvents = False
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual

and reset them after immediately after the loop and in any On Error trap
sections still holds.

Hi and thanks for the code.

To find the cells that contain formulas, it is simple to use
Selection.SpecialCells(xlCellTypeformulas, 3).Select
which will return formulas that contain text or numbers.

However it detects ALL formulas that equate to numbers - which is
logical.

I want to be able to interrogate the formula string e.g.

in cell C1 : =if(a1=b1,a1+100,a1-50)

and detect the 100 or the -50.

The reason I want to do this is the 100 or the -50 are hard coded
constants
that unless you know they are there, will always affect the result of
C1

I want to highlight C1 as a cell that contains a formula driven by
literals.

The correct way to approach this would be:

Cell d1 : 100 (input value)
Cell d2 : -50 (input value)
cell c1 : =if(a1=b1,a1+d1,a1+d2)

in which case C1 would remain unhighlighted.

Clearer? :)

Bony

Hi Rick,
I really can't thank you enough. I did spot the problem with the row
numbers but thank you for being thorough. You have saved me many hours.

Have a great day!

Default Formulas containing hard coded values

.... interesting change to the second version ... I like how you reference the
precedents.areas - master stroke.

I did notice though that if you use either version of your function with a
formula that contains a range modifyer - e.g. match, it detects the ,1 or ,0
as a literal. So it seems to work for simple formulas but not for formulas
with elements. sigh ...

So I tried this ...

Sub rc_cell_integrity()
Dim R As Range, sdoit As String
Set R = ActiveCell
Application.EnableEvents = False
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
sdoit = IsRefOnly(R)
Application.EnableEvents = True
Application.ScreenUpdating = True
Application.Calculation = xlCalculationSemiautomatic
If sdoit = False Then
MsgBox "Cell contains hard codes"
Else
MsgBox "Cell is good"
End If
End Sub

Function IsRefOnly(R As Range) As Boolean
' Returns True if the cell is "pure" or false if the cell has embedded
numbers or operators
' Grateful thanks to Rick Rothstein
Dim X As Long, Rw As Long
Dim Rng As Range, Cel As Range
Dim Fml As String, LCtext As String
Dim UCtext As String, OriginalFormula As String
If R.Count 1 Then
err.Raise vbObjectError + 1001, "IsRefOnly Function", _
"Only one cell permitted in Range for this function!"
Exit Function
End If
OriginalFormula = R.Formula
R.Formula = LCase(R.Formula)
LCtext = R.Formula
R.Formula = UCase(R.Formula)
UCtext = R.Formula
R.Formula = OriginalFormula
If LCtext = UCtext Then
Fml = R.Formula
For Each Rng In R.Precedents.Areas
On Error Resume Next
Fml = Replace(Fml, ",0", "") ' replace
Fml = Replace(Fml, ",1", "") ' replace
For Each Cel In Rng
Debug.Print Fml
Fml = Replace(Fml, Cel.Row, "")
Next
Next
If Not Fml Like "*#*" Then IsRefOnly = True
End If
End Function

I spent a short time trying to mask the ,0 or ,1 so I could do it in one
statement but eh ...

This seems to work. It does what I want it to so once again many thanks!!

Kins regards,
Robert

that unless you know they are there, will always affect the result of
C1

I want to highlight C1 as a cell that contains a formula driven by
literals.

The correct way to approach this would be:

Cell d1 : 100 (input value)
Cell d2 : -50 (input value)
cell c1 : =if(a1=b1,a1+d1,a1+d2)

in which case C1 would remain unhighlighted.

Clearer? :)

Are you saying that for your IF Statement, you want something like
this

=IF(A1=B2,A3,A4)

rather than
=IF(A1=0,"True","False")

I think it could take some time to program all of the permutations
you
may
need. If you want to find the cells with formulas, try this
'Untested
Dim aWS as excel.Worksheet
Dim myRange as excel.range
dim r as excel.range

Set aWS = ActiveSheet
for each r in aWS.usedrange
if r.hasformula then
ig myrange is nothing then
set myrange = r
else
set myrange = union(myrange,r)
end if
end if
next r

if not myrange is nothing then
myrange.select
myrange.interior.colorindex = 36 'Changes the highlight if you
want
it.
end if

Alternatively, you can use the Formula Auditing functionality to see
all
of
the formulas as written out.

Default Formulas containing hard coded values

Give me some examples of the formulas the function doesn't work with and
I'll see if I can patch the code to account for them.

As for the last function I posted, it still has a flaw in it. Because I set
it up to remove the row number of cell addresses, there is a change I could
be replacing a numerical constant as well. As an example, 3*Row("A3")...
once I have identified A3, my code then replaced all 3's in the formula
text... that would mean the 3 multiplier would be removed as well, making it
impossible for the code to see the 3 multiplier. Here is some modified code
that eliminates this flaw (which you can use until you respond to my opening
sentence)...

Function IsRefOnly(R As Range) As Boolean
Dim X As Long, Rw As Long
Dim Rng As Range, Cel As Range
Dim Fml As String, LCtext As String
Dim UCtext As String, OriginalFormula As String
If R.Count 1 Then
Err.Raise vbObjectError + 1001, "IsRefOnly Function", _
"Only one cell permitted in Range for this function!"
Exit Function
End If
OriginalFormula = R.Formula
R.Formula = LCase(R.Formula)
LCtext = R.Formula
R.Formula = UCase(R.Formula)
UCtext = R.Formula
R.Formula = OriginalFormula
If LCtext = UCtext Then
Fml = Application.ConvertFormula(R.Formula, xlA1, xlA1, True)
For Each Rng In R.Precedents.Areas
For Each Cel In Rng
Fml = Replace(Fml, Cel.Address(True, True), "")
Next
Next
If Not Fml Like "*#*" Then IsRefOnly = True
End If
End Function

I did notice though that if you use either version of your function with a
formula that contains a range modifyer - e.g. match, it detects the ,1 or
,0
as a literal. So it seems to work for simple formulas but not for
formulas
with elements. sigh ...

So I tried this ...

Sub rc_cell_integrity()
Dim R As Range, sdoit As String
Set R = ActiveCell
Application.EnableEvents = False
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
sdoit = IsRefOnly(R)
Application.EnableEvents = True
Application.ScreenUpdating = True
Application.Calculation = xlCalculationSemiautomatic
If sdoit = False Then
MsgBox "Cell contains hard codes"
Else
MsgBox "Cell is good"
End If
End Sub

Function IsRefOnly(R As Range) As Boolean
' Returns True if the cell is "pure" or false if the cell has embedded
numbers or operators
' Grateful thanks to Rick Rothstein
Dim X As Long, Rw As Long
Dim Rng As Range, Cel As Range
Dim Fml As String, LCtext As String
Dim UCtext As String, OriginalFormula As String
If R.Count 1 Then
err.Raise vbObjectError + 1001, "IsRefOnly Function", _
"Only one cell permitted in Range for this function!"
Exit Function
End If
OriginalFormula = R.Formula
R.Formula = LCase(R.Formula)
LCtext = R.Formula
R.Formula = UCase(R.Formula)
UCtext = R.Formula
R.Formula = OriginalFormula
If LCtext = UCtext Then
Fml = R.Formula
For Each Rng In R.Precedents.Areas
On Error Resume Next
Fml = Replace(Fml, ",0", "") ' replace
Fml = Replace(Fml, ",1", "") ' replace
For Each Cel In Rng
Debug.Print Fml
Fml = Replace(Fml, Cel.Row, "")
Next
Next
If Not Fml Like "*#*" Then IsRefOnly = True
End If
End Function

I spent a short time trying to mask the ,0 or ,1 so I could do it in one
statement but eh ...

This seems to work. It does what I want it to so once again many thanks!!

Hi and thanks for the code.

To find the cells that contain formulas, it is simple to use
Selection.SpecialCells(xlCellTypeformulas, 3).Select
which will return formulas that contain text or numbers.

However it detects ALL formulas that equate to numbers - which is
logical.

I want to be able to interrogate the formula string e.g.

in cell C1 : =if(a1=b1,a1+100,a1-50)

and detect the 100 or the -50.

The reason I want to do this is the 100 or the -50 are hard coded
constants
that unless you know they are there, will always affect the result
of
C1

I want to highlight C1 as a cell that contains a formula driven by

The correct way to approach this would be:

Cell d1 : 100 (input value)
Cell d2 : -50 (input value)
cell c1 : =if(a1=b1,a1+d1,a1+d2)

in which case C1 would remain unhighlighted.

Clearer? :)

references and partial/full column references (such as 3:3, 5:12, A:A and
D:M)...

Function IsRefOnly(R As Range) As Boolean
Dim X As Long, Rw As Long

If R.Count 1 Then

For Each Rng In R.Precedents.Areas
For Each Cel In Rng

Default Formulas containing hard coded values

Hi Rick,
A typical formula that returns False would be the following:
match(a1,a5:a10,0) for absolute match or
match(a1,a5:a10,1) for closest match - both formulas are valid.

Hi and thanks for the code.

To find the cells that contain formulas, it is simple to use
Selection.SpecialCells(xlCellTypeformulas, 3).Select
which will return formulas that contain text or numbers.

However it detects ALL formulas that equate to numbers - which is
logical.

I want to be able to interrogate the formula string e.g.

in cell C1 : =if(a1=b1,a1+100,a1-50)

and detect the 100 or the -50.

The reason I want to do this is the 100 or the -50 are hard coded

No - I can see currentregion will not work. It doesn't allow the
For each cel in Rng to fully replace. Dang!

"There are 10 types of people in this world. Those who understand Binary

Also - an amendment to the above post - for vlookup and hlookup, the ,1 is a
range modifyer OR a column or row identifyer. In Match, the ,0 ,1 or ,-1 is
valid but does different things.

I guess it is unrealistic to expect this to work without some creative
judgement orinput ... what do you think?

Hi Rick,
A typical formula that returns False would be the following:

Default Formulas containing hard coded values

I figured when you said this...

"What I am trying to achieve is to highligt those
formulas that contain a numerical value or text
value that amends the result of the formula in a
non best practice way. Best practice dictates
that formulas should not contain hard coded
elements. All elements pertaining to a formula
should have a linked basis."

in your 2nd posting, that it was your practice to never have a numerical
constant in any of your formulas. From your statement, I would have expected
you to have the 0 and 1 in your examples stored in a cell and a cell
reference to them in your formula. If you are going to allow numerical
constants in certain situations, then I don't think you will be able to
achieve what you want 100% of the time... to do that, you would have to
duplicate the full Excel parser in code (which I think would be considerable
in size).

As for using CurrentRegion in place of the Precedents... no, I don't think
that would work at all for multiple, individual cells whose current regions
could extend well beyond their single occurrences. Did you use the three
Application property calls I mentioned in a previous message inside your own
code where I indicated they should go? Also, perhaps changing the inner loop
to this would help speed things up...

For Each Cel In Rng
If InStr(Fml, Cell.Address(True, True)) Then Fml = Replace( _
Fml, Cel.Address(True, True), "")
Next

If Not Fml Like "*#*" Then IsRefOnly = True
End If
End Function

My suggestion in my parallel post for you to use these immediately
before
your loop through the range returned by the SpecialCells property
...

Application.EnableEvents = False
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual

and reset them after immediately after the loop and in any On Error
trap
sections still holds.

Here is a function that I am pretty sure does what you want... it
tests
if a
*single* cell is "pure" in the sense you have described (no text
or
number
constants) returning True if it is and False if it is not. Use it
in
conjunction with the SpecialCells call you mentioned, looping
through
each
cell in the range it returns, testing each cell with the function
and
highlighting in anyway you chose those cells for which the
function
returns
False...

Function IsRefOnly(R As Range) As Boolean
Dim LCtext As String
Dim UCtext As String
Dim OriginalFormula As String
If R.Count 1 Then
Err.Raise vbObjectError + 1001, "IsRefOnly Function", _
"Only one cell permitted in Range for this
function!"
Exit Function
End If
OriginalFormula = R.Formula
R.Formula = LCase(R.Formula)
LCtext = R.Formula
R.Formula = UCase(R.Formula)
UCtext = R.Formula
R.Formula = OriginalFormula
If LCtext = UCtext Then
If Not R.Formula Like "*[!A-Z]#*" Then IsRefOnly = True
End If
End Function

Hi and thanks for the code.

To find the cells that contain formulas, it is simple to use
Selection.SpecialCells(xlCellTypeformulas, 3).Select
which will return formulas that contain text or numbers.

However it detects ALL formulas that equate to numbers - which
is
logical.

I want to be able to interrogate the formula string e.g.

in cell C1 : =if(a1=b1,a1+100,a1-50)

and detect the 100 or the -50.

The reason I want to do this is the 100 or the -50 are hard
coded
