Find anything but a number or "C" - vba

I have this formula (below) where I am trying to find a space in C1. Instead of this, I would like to update this formula to look for anything except for "C" or any number and not only find a space.
LEFT(C1, find("" "", C1, 1)-1)
For e.g.
if C1 has - "C1234 - XXX" or "C1234-XXX" or "C1234:XXX", I always want the above function to find anything except for "C" and "1234" (i.e. numbers).
P.S.: I would want to use the find function only with improvements to meet the above conditions.
Please suggest.

Perhaps this:
'To create a new string from a source string which will or will not contain the characters present within the source string
'Examples of string of characters: 0123456789 -OR- {}[]<>\/|+*=-_(),.:;?!##$%^&™®©~'" OR - combination of various characters
Public Function getNewStringFromString(ByVal strSource As Variant, ByVal strChars As Variant, Optional isInString As Boolean = True) As String
Dim strArr As Variant, iChar As Variant
getNewStringFromString = ""
If VarType(strSource) = vbString And VarType(strChars) = vbString Then
strSource = Trim(strSource): strChars = Trim(strChars)
If Len(strSource) > 0 And Len(strChars) > 0 Then
strArr = Split(StrConv(strSource, vbUnicode), vbNullChar)
For Each iChar In strArr
If (isInString Xor isInArray(iChar, strChars)) = False Then getNewStringFromString = getNewStringFromString + iChar
Next iChar
Erase strArr
End If
End If
End Function
Use as the following:
MsgBox getNewStringFromString(CStr(Range("C1")), "C0123456789")
Forgot to give you the code for the isInArray function. Here it is:
'To check if an element is within a specific Array, Object, Range, String, etc.
Public Function isInArray(ByVal itemSearched As Variant, ByVal aArray As Variant) As Boolean
Dim item As Variant
If VarType(aArray) >= vbArray Or VarType(aArray) = vbObject Or VarType(aArray) = vbDataObject Or TypeName(aArray) = "Range" Then
For Each item In aArray
If itemSearched = item Then
isInArray = True
Exit Function
End If
Next item
isInArray = False
ElseIf VarType(aArray) = vbString Then
isInArray = InStr(1, aArray, itemSearched, vbBinaryCompare) > 0 'Comparing character by character
Else
On Error Resume Next
isInArray = Not IsError(Application.Match(itemSearched, aArray, False))
Err.Clear: On Error GoTo 0
End If
End Function

Given your data format, where
C is always the first character
subsequent values are all digits
You want to return the C followed by the digits
Try:
="C" & LOOKUP(9E+307,VALUE(MID(A1,2,{1,2,3,4,5,6,7})))
If there might be more than 7 digits, you can either extend the array constant, or use a formula to create a larger array.
The formula looks for the largest integer in the string, starting with position 2. So it will stop at the last non-digit, since anything including a non-digit will return an error.
If the "non-digit" might be your decimal or thousands separator, you will need to replace it with something else, with a nested SUBSTITUTE
Replace . , and space with -
=LOOKUP(1E+307,--SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(MID(A1,2,{1,2,3,4,5,6,7}),",","-"),".","-"),".","-"))
For a VBA solution, I would use regular expressions.
Option Explicit
Function getCnum(str As String)
Dim RE As Object
Const sPat As String = "(^C\d+).*"
Set RE = CreateObject("vbscript.regexp")
With RE
.Global = False
.MultiLine = True
.ignorecase = True
.Pattern = sPat
getCnum = .Replace(str, "$1")
End With
End Function
Note that this also validates the string by checking that the first letter is, in fact, a C (or c). If you want it to be case-sensitive, make the obvious change.

Excel VBA Custom Function Remove Words Appearing in One String From Another String

I am trying to remove words appearing in one string from a different string using a custom function. For instance:
A1:
the was why blue hat
A2:
the stranger wanted to know why his blue hat was turning orange
The ideal outcome in this example would be:
A3:
stranger wanted to know his turning orange
I need to have the cells in reference open to change so that they can be used in different situations.
The function will be used in a cell as:
=WORDREMOVE("cell with words needing remove", "cell with list of words being removed")
I have a list of 20,000 rows and have managed to find a custom function that can remove duplicate words (below) and thought there may be a way to manipulate it to accomplish this task.
Function REMOVEDUPEWORDS(txt As String, Optional delim As String = " ") As String
Dim x
'Updateby20140924
With CreateObject("Scripting.Dictionary")
.CompareMode = vbTextCompare
For Each x In Split(txt, delim)
If Trim(x) <> "" And Not .exists(Trim(x)) Then .Add Trim(x), Nothing
Next
If .Count > 0 Then REMOVEDUPEWORDS = Join(.keys, delim)
End With
End Function
If you can guarantee that your words in both strings will be separated by spaces (no comma, ellipses, etc), you could just Split() both strings then Filter() out the words:
Function WORDREMOVE(ByVal strText As String, strRemove As String) As String
Dim a, w
a = Split(strText) ' Start with all words in an array
For Each w In Split(strRemove)
a = Filter(a, w, False, vbTextCompare) ' Remove every word found
Next
WORDREMOVE = Join(a, " ") ' Recreate the string
End Function
You can also do this using Regular Expressions in VBA. The version below is case insensitive and assumes all words are separated only by space. If there is other punctuation, more examples would aid in crafting an appropriate solution:
Option Explicit
Function WordRemove(Str As String, RemoveWords As String) As String
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")
With RE
.ignorecase = True
.Global = True
.Pattern = "(?:" & Join(Split(WorksheetFunction.Trim(RemoveWords)), "|") & ")\s*"
WordRemove = .Replace(Str, "")
End With
End Function
My example is certainly not the best code, but it should work
Function WORDREMOVE(FirstCell As String, SecondCell As String)
Dim FirstArgument As Variant, SecondArgument As Variant
Dim FirstArgumentCounter As Integer, SecondArgumentCounter As Integer
Dim Checker As Boolean
WORDREMOVE = ""
FirstArgument = Split(FirstCell, " ")
SecondArgument = Split(SecondCell, " ")
For SecondArgumentCounter = 0 To UBound(SecondArgument)
Checker = False
For FirstArgumentCounter = 0 To UBound(FirstArgument)
If SecondArgument(SecondArgumentCounter) = FirstArgument(FirstArgumentCounter) Then
Checker = True
End If
Next FirstArgumentCounter
If Checker = False Then WORDREMOVE = WORDREMOVE & SecondArgument(SecondArgumentCounter) & " "
Next SecondArgumentCounter
WORDREMOVE = Left(WORDREMOVE, Len(WORDREMOVE) - 1)
End Function

VBA string interpolation syntax

What is the VBA string interpolation syntax? Does it exist?
I would to to use Excel VBA to format a string.
I have a variable foo that I want to put in a string for a range.
Dim row as Long
row = 1
myString = "$row:$row"
I would like the $row in the string to be interpolated as "1"
You could also build a custom Format function.
Public Function Format(ParamArray arr() As Variant) As String
Dim i As Long
Dim temp As String
temp = CStr(arr(0))
For i = 1 To UBound(arr)
temp = Replace(temp, "{" & i - 1 & "}", CStr(arr(i)))
Next
Format = temp
End Function
The usage is similar to C# except that you can't directly reference variables in the string. E.g. Format("This will {not} work") but Format("This {0} work", "will").
Public Sub Test()
Dim s As String
s = "Hello"
Debug.Print Format("{0}, {1}!", s, "World")
End Sub
Prints out Hello, World! to the Immediate Window.
This works well enough, I believe.
Dim row as Long
Dim s as String
row = 1
s = "$" & row & ":$" & row
Unless you want something similar to Python's or C#'s {} notation, this is the standard way of doing it.
Using Key\Value Pairs
Another alternative to mimic String interpolation is to pass in key\value pairs as a ParamArray and replace the keys accordingly.
One note is that an error should be raised if there are not an even number of elements.
' Returns a string that replaced special keys with its associated pair value.
Public Function Inject(ByVal source As String, ParamArray keyValuePairs() As Variant) As String
If (UBound(keyValuePairs) - LBound(keyValuePairs) + 1) Mod 2 <> 0 Then
Err.Raise 5, "Inject", "Invalid parameters: expecting key/value pairs, but received an odd number of arguments."
End If
Inject = source
' Replace {key} with the pairing value.
Dim index As Long
For index = LBound(keyValuePairs) To UBound(keyValuePairs) Step 2
Inject = Replace(Inject, "{" & keyValuePairs(index) & "}", keyValuePairs(index + 1), , , vbTextCompare)
Next index
End Function
Simple Example
Here is a simple example that shows how to implement it.
Private Sub testingInject()
Const name As String = "Robert"
Const age As String = 31
Debug.Print Inject("Hello, {name}! You are {age} years old!", "name", name, "age", age)
'~> Hello, Robert! You are 31 years old!
End Sub
Although this may add a few extra strings, in my opinion, this makes it much easier to read long strings.
See the same simple example using concatenation:
Debug.Print "Hello, " & name & "! You are " & age & " years old!"
Using Scripting.Dicitionary
Really, a Scripting.Dictionary would be perfect for this since they are nothing but key/value pairs. It would be a simple adjustment to my code above, just take in a Dictionary as the parameter and make sure the keys match.
Public Function Inject(ByVal source As String, ByVal data As Scripting.Dictionary) As String
Inject = source
Dim key As Variant
For Each key In data.Keys
Inject = Replace(Inject, "{" & key & "}", data(key))
Next key
End Function
Dictionary example
And the example of using it for dictionaries:
Private Sub testingInject()
Dim person As New Scripting.Dictionary
person("name") = "Robert"
person("age") = 31
Debug.Print Inject("Hello, {name}! You are {age} years old!", person)
'~> Hello, Robert! You are 31 years old!
End Sub
Additional Considerations
Collections sound like they would be nice as well, but there is no way of accessing the keys. It would probably get messier that way.
If using the Dictionary method you might create a simple factory function for easily creating Dictionaries. You can find an example of that on my Github Library Page.
To mimic function overloading to give you all the different ways you could create a main Inject function and run a select statement within that.
Here is all the code needed to do that if need be:
Public Function Inject(ByVal source As String, ParamArray data() As Variant) As String
Dim firstElement As Variant
assign firstElement, data(LBound(data))
Inject = InjectCharacters(source)
Select Case True
Case TypeName(firstElement) = "Dictionary"
Inject = InjectDictionary(Inject, firstElement)
Case InStr(source, "{0}") > 0
Inject = injectIndexes(Inject, CVar(data))
Case (UBound(data) - LBound(data) + 1) Mod 2 = 0
Inject = InjectKeyValuePairs(Inject, CVar(data))
Case Else
Err.Raise 5, "Inject", "Invalid parameters: expecting key/value pairs or Dictionary or an {0} element."
End Select
End Function
Private Function injectIndexes(ByVal source As String, ByVal data As Variant)
injectIndexes = source
Dim index As Long
For index = LBound(data) To UBound(data)
injectIndexes = Replace(injectIndexes, "{" & index & "}", data(index))
Next index
End Function
Private Function InjectKeyValuePairs(ByVal source As String, ByVal keyValuePairs As Variant)
InjectKeyValuePairs = source
Dim index As Long
For index = LBound(keyValuePairs) To UBound(keyValuePairs) Step 2
InjectKeyValuePairs = Replace(InjectKeyValuePairs, "{" & keyValuePairs(index) & "}", keyValuePairs(index + 1))
Next index
End Function
Private Function InjectDictionary(ByVal source As String, ByVal data As Scripting.Dictionary) As String
InjectDictionary = source
Dim key As Variant
For Each key In data.Keys
InjectDictionary = Replace(InjectDictionary, "{" & key & "}", data(key))
Next key
End Function
' QUICK TOOL TO EITHER SET OR LET DEPENDING ON IF ELEMENT IS AN OBJECT
Private Function assign(ByRef variable As Variant, ByVal value As Variant)
If IsObject(value) Then
Set variable = value
Else
Let variable = value
End If
End Function
End Function
Private Function InjectCharacters(ByVal source As String) As String
InjectCharacters = source
Dim keyValuePairs As Variant
keyValuePairs = Array("n", vbNewLine, "t", vbTab, "r", vbCr, "f", vbLf)
If (UBound(keyValuePairs) - LBound(keyValuePairs) + 1) Mod 2 <> 0 Then
Err.Raise 5, "Inject", "Invalid variable: expecting key/value pairs, but received an odd number of arguments."
End If
Dim RegEx As Object
Set RegEx = CreateObject("VBScript.RegExp")
RegEx.Global = True
' Replace is ran twice since it is possible for back to back patterns.
Dim index As Long
For index = LBound(keyValuePairs) To UBound(keyValuePairs) Step 2
RegEx.Pattern = "((?:^|[^\\])(?:\\{2})*)(?:\\" & keyValuePairs(index) & ")+"
InjectCharacters = RegEx.Replace(InjectCharacters, "$1" & keyValuePairs(index + 1))
InjectCharacters = RegEx.Replace(InjectCharacters, "$1" & keyValuePairs(index + 1))
Next index
End Function
I have a library function SPrintF() which should do what you need.
It replaces occurrences of %s in the supplied string with an extensible number of parameters, using VBA's ParamArray() feature.
Usage:
SPrintF("%s:%s", 1, 1) => "1:1"
SPrintF("Property %s added at %s on %s", "88 High St, Clapham", Time, Date) => ""Property 88 High St, Clapham added at 11:30:27 on 25/07/2019"
Function SprintF(strInput As String, ParamArray varSubstitutions() As Variant) As String
'Formatted string print: replaces all occurrences of %s in input with substitutions
Dim i As Long
Dim s As String
s = strInput
For i = 0 To UBound(varSubstitutions)
s = Replace(s, "%s", varSubstitutions(i), , 1)
Next
SprintF = s
End Function
Just to add as a footnote, the idea for this was inspired by the C language printf function.
I use a similar code to that of #natancodes except that I use regex to replace the occurances and allow the user to specifiy description for the placeholders. This is useful when you have a big table (like in Access) with many strings or translations so that you still know what each number means.
Function Format(ByVal Source As String, ParamArray Replacements() As Variant) As String
Dim Replacement As Variant
Dim i As Long
For i = 0 To UBound(Replacements)
Dim rx As New RegExp
With rx
.Pattern = "{" & i & "(?::(.+?))?}"
.IgnoreCase = True
.Global = True
End With
Select Case VarType(Replacements(i))
Case vbObject
If Replacements(i) Is Nothing Then
Dim Matches As MatchCollection
Set Matches = rx.Execute(Source)
If Matches.Count = 1 Then
Dim Items As SubMatches: Set Items = Matches(0).SubMatches
Dim Default As String: Default = Items(0)
Source = rx.Replace(Source, Default)
End If
End If
Case vbString
Source = rx.Replace(Source, CStr(Replacements(i)))
End Select
Next
Format = Source
End Function
Sub TestFormat()
Debug.Print Format("{0:Hi}, {1:space}!", Nothing, "World")
End Sub

Find and replace all names of variables in VBA module

Let's assume that we have one module with only one Sub in it, and there are no comments. How to identify all variable names ? Is it possible to identify names of variables which are not defined using Dim ? I would like to identify them and replace each with some random name to obfuscate my code (O0011011010100101 for example), replace part is much easier.
List of characters which could be use in names of macros, functions and variables :
ABCDEFGHIJKLMNOPQRSTUVWXYZdefghijklmnopqrstuvwxyzg€‚„…†‡‰Š‹ŚŤŽŹ‘’“”•–—™š›śťžź ˇ˘Ł¤Ą¦§¨©Ş«¬­®Ż°±˛ł´µ¶·¸ąş»Ľ˝ľżŔÁÂĂÄĹĆÇČÉĘËĚÍÎĎĐŃŇÓÔŐÖ×ŘŮÚŰÜÝŢßŕáâăäĺćçčéęëěíîďđńňóôőö÷řůúűüýţ˙ÉĘËĚÍÎĎĐŃŇÓÔŐÖ×ŘŮÚŰÜÝŢßŕáâăäĺćçčéęëěíîďđńňóôőö÷řůúűüýţ˙
Below are my function I've wrote recenlty :
Function randomName(n as integer) as string
y="O"
For i = 2 To n:
If Rnd() > 0.5 Then
y = y & "0"
Else
y = y & "1"
End If
Next i
randomName=y
End Function
In goal to replace given strings in another string which represent the code of module I use below sub :
Sub substituteNames()
'count lines in "Module1" which is part of current workbook
linesCount = ActiveWorkbook.VBProject.VBComponents("Module1").CodeModule.CountOfLines
'read code from module
code = ActiveWorkbook.VBProject.VBComponents("Module1").CodeModule.Lines(StartLine:=1, Count:=linesCount)
inputStr = Array("name1", "name2", "name2") 'some hardwritten array with string to replace
namesLength = 20 'length of new variables names
For i = LBound(inputStr) To UBound(inputStr)
outputString = randomName(namesLength-1)
code = Replace(code, inputStr(i), outputString)
Next i
Debug.Print code 'view code
End Sub
then we simply substitute old code with new one, but how to identify strings with names of variables ?
Edition
Using **Option Explicit ** decrease safety of my simple method of obfuscation, because to reverse changes you only have to follow Dim statements and replace ugly names with something normal. Except that to make such substitution harder, I think it's good idea to break the line in the middle of variable name :
O0O000O0OO0O0000 _
0O00000O0OO0
the simple method is also replacing some strings with chains based on chr functions chr(104)&chr(101)&chr(108)&chr(108)&chr(111) :
Sub stringIntoChrChain()
strInput = "hello"
strOutput = ""
For i = 1 To Len(strInput)
strOutput = strOutput & "chr(" & Asc(Mid(strInput, i, 1)) & ")&"
Next i
Debug.Print Mid(strOutput, 1, Len(strOutput) - 1)
End Sub
comments like below could make impression on user and make him think that he does not poses right tool to deal with macro etc.:

You can use a regular expression to find variable assignments by looking for the equals sign. You'll need to add a reference to the Microsoft VBScript Regular Expressions 5.5 and Microsoft Visual Basic for Applications Extensibility 5.3 libraries as I've used early binding.
Please be sure to back up your work and test this before using it. I could have gotten the regex wrong.
UPDATE:
I've refined the regular expressions so that it no longer catches datatypes of strongly typed constants (Const ImAConstant As String = "Oh Noes!" previously returned String). I've also added another regex to return those constants as well. The last version of the regex also mistakenly caught things like .Global = true. That was corrected. The code below should return all variable and constant names for a given code module. The regular expressions still aren't perfect, as you'll note that I was unable to stop false positives on double quotes. Also, my array handling could be done better.

optimal code for detecting formatting differences?

I need to compare two formatted strings. The text in the two of them is the same, only the formatting differs, meaning that some words are bold. The code should tell me if the location of the bold substrings are different e.g. the strings are formatted differently.
So far I tried a char-to-char approach, but it is far too slow.
It's a plain legal current text in MS Word, with cca 10-500 chars per string. Two people independently formatted the strings.
my code so far:
Function collectBold(r As Range) As String
Dim chpos As Integer
Dim ch As Variant
Dim str, strTemp As String
chpos = 1
Do
If r.Characters(chpos).Font.Bold Then
Do
Dim boold As Boolean
strTemp = strTemp + r.Characters(chpos)
chpos = chpos + 1
If (chpos < r.Characters.Count) Then boold = r.Characters(chpos).Font.Bold
Loop While (boold And chpos < r.Characters.Count)
str = str + Trim(strTemp) + "/"
strTemp = ""
Else: chpos = chpos + 1
End If
Loop While (chpos < r.Characters.Count)
collectBold = str
End Function
This code collect all bold substrings (strTemp) and merges them into one string (str), separating them with "/". The function runs for both strings to compare, and then checks if the outputs are the same.
If you only need to see if they are different, this function will do it:
Function areStringsDifferent(range1 As Range, range2 As Range) As Boolean
Dim i As Integer, j As Integer
For i = 1 To range1.Words.Count
'check if words are different formatted
If Not range1.Words(i).Bold = range2.Words(i).Bold Then
areStringsDifferent = True
Exit Function
'words same formatted, but characters may not be
ElseIf range1.Words(i).Bold = wdUndefined Then
For j = 1 To range1.Words(i).Characters.Count
If Not range1.Words(i).Characters(j).Bold = range2.Words(i).Characters(j).Bold Then
areStringsDifferent = True
Exit Function
End If
Next
End If
Next
areStringsDifferent = False
End Function
It first looks if the words are different formatted... If they have the same format but the format is undefinied, it looks into the characters of the word.

Get the value between the brackets

I have a column with some stuff that looks like the following string: V2397(+60)
How do I get the value between the brackets? In this case the +60.
The number (and character) before the brackets is not something standardized and neither the number between the brackets (it can be 100, 10 -10 or even 0...).
VBA code:
cellValue = "V2397(+60)"
openingParen = instr(cellValue, "(")
closingParen = instr(cellValue, ")")
enclosedValue = mid(cellValue, openingParen+1, closingParen-openingParen-1)
Obviously cellValue should be read from the cell.
Alternatively, if cell A1 has one of these values, then the following formula can be used to extrcat the enclosed value to a different cell:
=Mid(A1, Find("(", A1)+1, Find(")",A1)-Find("(",A1)-1)
I would use a regular expression for this as it easily handles
a no match case
multiple matches in one string if required
more complex matches if your parsing needs evolve
The Test sub runs three sample string tests
The code below uses a UDF which you could call directly in Excel as well, ie = GetParen(A10)
Function GetParen(strIn As String) As String
Dim objRegex As Object
Dim objRegMC As Object
Set objRegex = CreateObject("vbscript.regexp")
With objRegex
.Pattern = "\((.+?)\)"
If .Test(strIn) Then
Set objRegMC = .Execute(strIn)
GetParen = objRegMC(0).submatches(0)
Else
GetParen = "No match"
End If
End With
Set objRegex = Nothing
End Function
Sub Test()
MsgBox GetParen("V2397(+60)")
MsgBox GetParen("Not me")
MsgBox GetParen(ActiveSheet.Range("A1"))
End Sub
Use InStr to get the index of the open bracket character and of the close bracket character; then use Mid to retrieve the desired substring.
Using InStr$ and Mid$ will perform better, if the parameters are not variants.
Thanks to Andrew Cooper for his answer.
For anyone interested I refactored into a function...
Private Function GetEnclosedValue(query As String, openingParen As String, closingParen As String) As String
Dim pos1 As Long
Dim pos2 As Long
pos1 = InStr(query, openingParen)
pos2 = InStr(query, closingParen)
GetEnclosedValue = Mid(query, (pos1 + 1), (pos2 - pos1) - 1)
End Function
To use
value = GetEnclosedValue("V2397(+60)", "(", ")" )
