Help with VBA InStr() function
 

2003 & 2007


ActiveCell.Formula ='P:\DMB\[MyWorkBook.xls]Allocation '!$U$77*1000000-
_
'P:\DMB\[MyWorkBook.xls]Allocation '!$U$85

Current VBA code to isolate the first cell reference follows:

BeginStr = Left(ActiveCell.Formula, InStr(ActiveCell.Formula, "!") +
1))
CellRefStr = InStr(BeginStr, ActiveCell.Formula, "*")
? CellRefStr yields $U$77 but only if the Operator is "*"

1) How best can I code "*" in the above InStr() so as to substitute it
with ANY
Operator? i.e., Operators = Array("/", "+", "-", "[*]", "",
"<", "=")
2) How then to yield $U$85 ?

Ultimately my End Game is to isolate the each Cell Reference (could be
many!)
after each WorkBook Worksheet reference in the ActiveCell.Formula.

Because there could be many Cell References my initial approach above
may
well be inappropriate or the long way around the barn.

Any help appreciated greatly!

You may want to consider using the precedents and dependents property
of the cell. You can see how I did it in my Formula Map program
in this post... http://tinyurl.com/yedjlw

Jim,

Thanks for your time and thoughts.

I did look at yur code and I may have missed something obvious,
but the "Precedents" property does not yield what I
need when there is a link to another Workbook; Worksheet.

That is correct.
It starts getting complicated if you go off sheet.
That feature is on my to-do list. However, I may never get to it
as the response to the Formula Map code was almost non-existent.

Jim,

Your code was a life-saver to me in 2006. I may have not communicated
that to you at the time.
BTW, my comment was/is not a guilt-trip nor a pressure tactic.

Do you know any other reliable way to isolate even the first cell
reference in an ActiveCell.Formula
when there is a WorkBook and Worksheet link?

Jim,

I should have mentioned that the following code works:

BeginStr = Len(Left(ActiveCell.Formula, InStr(ActiveCell.Formula,
"'!") + 1))
EndStr = InStr(BeginStr, ActiveCell.Formula, "?????????????")

If I could figure how to "replace" "?????????????" (above) with any
Operator
like + - * / = the challenge is solved.

Is there a function which will give me the string position of any
(or minimally the first) operator in ActiveCell.Formula?

If this is any help, would you at least consider not bottom posting? <g

This revised version should do a better job of finding the last operator.

I can't quite follow, but are there any ideas here that can help?
I have set a vba library reference to the reference below.

Sub Demo()
'// = = = = = = = = = =
'// Microsoft VbScript Regular Expressions 5.5
'// = = = = = = = = = =

Dim Re
Dim MyEquation As String
Dim LookFor As String
Dim AllPositions
Dim Position

MyEquation = "=A1*B1/3.4+3-2"

'// Find all positions of + - * /
LookFor = "[\+ \- \* \/]"

Set Re = New RegExp
Re.Pattern = LookFor
Re.IgnoreCase = True
Re.Global = True

Set AllPositions = Re.Execute(MyEquation)

MsgBox "Found: " & AllPositions.Count

For Each Position In AllPositions ' 0-Indexed
Debug.Print Position.FirstIndex + 1
Next Position
End Sub


Returns:

Found: 4
4
7
11
13

Here's my attempt at finding the two cell addresses.
There's not a lot of logic here. It just looks at the characters following
the "!" Character.
There may be a better technique. I shortened the string a little.

Returns:

Found: 2
$U$77
$U$85

Sub Demo()
'// = = = = = = = = = =
'// Microsoft VbScript Regular Expressions 5.5
'// = = = = = = = = = =

Dim Re As RegExp
Dim MyEquation As String
Dim AllPositions As MatchCollection
Dim Position As Match

'// Looking for a cell Address:
Const LookFor As String = "![$ 0-9 A-Z]+"

MyEquation = "'P:\[Book.xls]Allo'!$U$77*10-'P:\DMB\[Book.xls]Allo'!$U$85"

Set Re = New RegExp
Re.Pattern = LookFor
Re.IgnoreCase = True
Re.Global = True

If Not Re.Test(MyEquation) Then Exit Sub
Set AllPositions = Re.Execute(MyEquation)
Debug.Print "Found: " & AllPositions.Count

For Each Position In AllPositions ' 0-Indexed
Debug.Print Mid$(Position.Value, 2)
Next Position
End Sub
