I have a string like
string = "computer prog <5spaces> data mining <5spaces> oops concept"
As we can see clearly computer prog, data mining etc., are one continuous string and the delimiter is 5 spaces between the strings " ".
I need to split based on this in vb.net - so far I tried regex.split which works but results in giving 2 empty strings additionally and it's tedious to remove those additional strings.
I also tried using the string.split method but again it's taking even single white space also delimiters.
Below are the tried options:
regex.split
string.split
None give me the required result. I am not sure what I need to use. I even tried the option of stringsplitoption.removesapceentry (something like that) to get the desired result inside the split method, but none worked.
Dim array_keyskills As String() = res.Split(" ".ToCharArray,StringSplitOptions.RemoveEmptyEntries)
system.Windows.MessageBox.Show(array_keyskills(2) & array_keyskills.Length & " key skills") 'Display
The following short program:
Module Module1
Sub Main()
Dim s = "computer prog data mining oops concept"
Dim parts = s.Split({" "}, StringSplitOptions.None)
For Each p In parts
Console.WriteLine(p)
Next
Console.ReadLine()
End Sub
End Module
outputs:
computer prog
data mining
oops concept
If your data does not work that way then you should examine it to find which whitespace characters are in it which appear to be spaces but are not.
This did the trick:
array_keyskills = System.Text.RegularExpressions.Regex.Split(res," ").Where(
Function(s) Not String.IsNullOrWhitespace(s)
).ToArray()

I need to replace non-printable characters with " (Inch sign).
I tried to use excel clean function and other UDF functions, but it just remove and not replace.
Note: non-printable characters are highlighted in blue on the above photo and it's position is random on the cells.
this is a sample string file Link`
The expected correct output should be 12"x14" LPG . OUTLET OCT-SEP# process
In advance grateful for useful comments and answer.
As per my comment, you can try:
=SUBSTITUTE(A1,CHAR(25)&CHAR(25),CHAR(34))
Or the VBA pseudo-code:
[A1] = [A1].Replace(Chr(25) & Chr(25), Chr(34))
Where [A1] is the obvious placeholder for the range-object you would want to use with proper and absolute referencing.
With ms365 newest functions, we could also use:
=TEXTJOIN(CHAR(34),,TEXTSPLIT(A1,CHAR(25)))
You can use Regular Expressions within a UDF to create a flexible method to replace "bad" characters, when you don't know exactly what they are.
In the UDF below, I show two pattern options, but others are possible.
One is to replace all characters with a character code >127
the second is to replace all characters with a charcter code >255
Option Explicit
Function ReplaceBadChars(str As String, replWith As String) As String
Dim RE As Object
Set RE = CreateObject("Vbscript.Regexp")
With RE
.Pattern = "[\u0080-\uFFFF]" 'to replace all characters with code >127 or
'.Pattern = "[\u0100-\uFFFF]" 'to replace all characters with code >255
.Global = True
ReplaceBadChars = .Replace(str, replWith)
End With
End Function
On the worksheet you can use, for example:
=ReplaceBadChars(A1,"""")
Or you could use it in a macro if you wanted to process a column of data without adding an extra column.
Note: I am uncertain as to whether there might be an efficiency difference using a smaller negated character class (eg: [^\x00-\x79] instead of the character class I showed in the code. But if, as written, execution seems slow, I'd try this change)
You can try this :
Cells.Replace What:="[The caracter to replace]", Replacement:=""""
I am trying to bold specific words based on a string being read into vba code.
I have the string in read into vba and now want to pick out a word or words to bold them.
If the following was read into vba code: The boy ran down the street.
In the above sentence, what code would I use if I wanted to bold just the word boy? What would I use if I wanted to bold the words boy and the?
I have tried the following code but do not know how to modify it to my specific case.
https://code.adonline.id.au/vba-format-text-microsoft-word/
In short, I want code that will read in a string, search that string for x amount of words, and bold said words to be later exported.
Let me know if you need any more details and what I am trying to accomplish.
Excel is pretty good at formatting whole cells, but it's not very good at formatting parts of cells. One way that I've been able to do this is to turn the text into very basic HTML and then paste the text into a cell. Here's an example.
Public Sub BoldCertainWords()
Dim sSentence As String
Dim dobj As DataObject
Set dobj = New DataObject
sSentence = "The boy ran down the street"
sSentence = Replace$(sSentence, "boy", "<strong>boy</strong>")
sSentence = Replace$(sSentence, "the", "<strong>the</strong>")
dobj.SetText "<html>" & sSentence & "</html>"
dobj.PutInClipboard
Sheet1.Range("A1").Select
Sheet1.PasteSpecial "Unicode Text"
End Sub
You need to set a reference to the MS Forms 2.0 library to get the DataObject if you don't already have it.
Note also that case matters. This will bold the but not The. You could repeat for typical capitalization or get clever with how you find the words and build the HTML string.
Also note that this particular PastSpecial method is Worksheet method, not a Range method. You have to select the range first.
I have a cell that contains multiple questions and answers and is organised like a CSV. So to get all these questions and answers separated a simple split using the comma as the delimiter should separate this easily.
Unfortunately, there are some values that use the comma as the decimal separator. Is there a way to escape the split for those occurrences?
Fortunately, my data can be split using ", " as separator, but if this wouldn't be the case, would there still be a solution besides manually replacing the decimal delimiter from a comma to a dot?
Example:
"Price: 0,09,Quantity: 12,Sold: Yes"
Using Split("Price: 0,09,Quantity: 12,Sold: Yes",",") would yield:
Price: 0
09
Quantity: 12
Sold: Yes
One possibility, given this test data, is to loop through the array after splitting, and whenever there's no : in the string, add this entry to the previous one.
The function that does this might look like this:
Public Function CleanUpSeparator(celldata As String) As String()
Dim ret() As String
Dim tmp() As String
Dim i As Integer, j As Integer
tmp = Split(celldata, ",")
For i = 0 To UBound(tmp)
If InStr(1, tmp(i), ":") < 1 Then
' Put this value on the previous line, and restore the comma
tmp(i - 1) = tmp(i - 1) & "," & tmp(i)
tmp(i) = ""
End If
Next i
j = 0
ReDim ret(j)
For i = 0 To UBound(tmp)
If tmp(i) <> "" Then
ret(j) = tmp(i)
j = j + 1
ReDim Preserve ret(j)
End If
Next i
ReDim Preserve ret(j - 1)
CleanUpSeparator = ret
End Function
Note that there's room for improvement by making the separator caharacters : and , into parameters, for instance.
I spent the last 24 hours or so puzzling over what I THINK is a completely analogous problem, so I'll share my solution here. Forgive me if I'm wrong about the applicability of my solution to this question. :-)
My Problem: I have a SharePoint list in which teachers (I'm an elementary school technology specialist) enter end-of-year award certificates for me to print. Teachers can enter multiple students' names for a given award, separating each name using a comma. I have a VBA macro in Access that turns each name into a separate record for mail merging. Okay, I lied. That was more of a story. HERE'S the problem: How can teachers add a student name like Hank Williams, Jr. (note the comma) without having the comma cause "Jr." to be interpreted as a separate student in my macro?
The full contents of the (SharePoint exported to Excel) field "Students" are stored within the macro in a variable called strStudentsBeforeSplit, and this string is eventually split with this statement:
strStudents = Split(strStudentsBeforeSplit, ",", -1, vbTextCompare)
So there's the problem, really. The Split function is using a comma as a separator, but poor student Hank Williams, Jr. has a comma in his name. What to do?
I spent a long time trying to figure out how to escape the comma. If this is possible, I never figured it out.
Lots of forum posts suggested using a different character as the separator. That's okay, I guess, but here's the solution I came up with:
Replace only the special commas preceding "Jr" with a different, uncommon character BEFORE the Split function runs.
Swap back to the commas after Split runs.
That's really the end of my post, but here are the lines from my macro that accomplish step 1. This may or may not be of interest because it really just deals with the minutiae of making the swap. Note that the code handles several different (mostly wrong) ways my teachers might type the "Jr" part of the name.
'Dealing with the comma before Jr. This will handle ", Jr." and ", Jr" and " Jr." and " Jr".
'Replaces the comma with ~ because commas are used to separate fields in Split function below.
'Will swap ~ back to comma later in UpdateQ_Comma_for_Jr query.
strStudentsBeforeSplit = Replace(strStudentsBeforeSplit, "Jr", "~ Jr.") 'Every Jr gets this treatment regardless of what else is around it.
'Note that because of previous Replace functions a few lines prior, the space between the comma and Jr will have been removed. This adds it back.
strStudentsBeforeSplit = Replace(strStudentsBeforeSplit, ",~ Jr", "~ Jr") 'If teacher had added a comma, strip it.
strStudentsBeforeSplit = Replace(strStudentsBeforeSplit, " ~ Jr", "~ Jr") 'In cases when teacher added Jr but no comma, remove the (now extra)...
'...space that was before Jr.
I have a frustrating problem. I have a string containg other characters that are not in this list (check link). My string represents a SQL Query.
This is an example of what my string can contain: INSERT INTO test (description) VALUES ('≤ ≥ >= <=')
When I check the database, the row is inserted successfully, but the characters "≤" and "≥" are replaced with "=" character.
In the database the string in description column looks like "= = >= <=".
For the most characters I can get a character code. I googled a character code for those two symbols, but I didn't find one. My goal is to check if my string contains this two characters , and afterwards replace them with ">=" and "<="
===Later Edit===
I have tried to check every character in a for loop;
tmp = Mid$(str, i, 1)
tmp will have the value "=" when my for loop reaches the "≤" character, so Excel cannot read this "≤" character in a VB string, then when I'm checking for character code I get the code for "=" (Chr(61))
Are you able to figure out what the character codes for both "≤" and "≥" in your database character set are? if so then maybe try replacing both characters in your query string with chrw(character_code).
I have just tested something along the lines of what you are trying to do using Excel as my database - and it looks to work fine.
Edit: assuming you are still stuck and looking for assistance here - could you confirm what database you are working with, and any type information setting for the "description" field you are looking to insert your string into?
Edit2: I am not familiar with SQL server, but isn't your "description" field set up to be of a certain data type? if so what is it and does it support unicode characters? ncharvar, nchar seem to be examples of sql server data types that support Unicode.
It sounds like you may also want to try and add an "N" prefix to the value in your query string - see
Do I have use the prefix N in the "insert into" statement for unicode? &
how to insert unicode text to SQL Server from query window
Edit3: varchar won't qualify for proper rendering of Unicode - see here What is the difference between varchar and nvarchar?. Can you switch to nvarchar? as mentionned above, you may also want to prefix the values in your query string with 'N' for full effect
Edit4: I can't speak much more about sqlserver, but what you are looking at here is how VBA displays the character, not at how it actually stores it in memory - which is the bottom line. VBA won't display "≤" properly since it doesn't support the Unicode character set. However, it may - and it does - store the binary representation correctly.
For any evidence of this, just try and paste back the character to another cell in Excel from VBA, and you will retrieve the original character - or look at the binary representation in VBA:
Sub test()
Dim s As String
Dim B() As Byte
'8804 is "≤" character in Excel character set
s = ChrW(8804)
'Assign memory representation of s to byte array B
B = s
'This loop prints "100" and "34", respectively the low and high bytes of s coding in memory
'representing binary value 0010 0010 0110 0100 ie 8804
For i = LBound(B) To UBound(B)
Debug.Print B(i)
Next i
'This prints "=" because VBA can not render character code 8804 properly
Debug.Print s
End Sub
If I copy your text INSERT INTO test (description) VALUES ('≤ ≥ >= <=') and paste it into the VBA editor, it becomes INSERT INTO test (description) VALUES ('= = >= <=').
If I paste that text into a Excel cell or an Access table's text field, it pastes "correctly".
This seems to be a matter of character code supported, and I suggest you have a look at this SO question.
But where in you program does that string come from, since it cannot be typed in VBA ??
Edit: I jus gave it a try with the below code, and it works like a charm for transferring your exotic characters from the worksheet to a table !
Sub test1()
Dim db As Object, rs As Object, cn As Object
Set cn = CreateObject("DAO.DBEngine.120")
Set db = cn.OpenDatabase("P:\Database1.accdb")
Set rs = db.OpenRecordset("table1")
With rs
.addnew
.Fields(0) = Range("d5").Value
.Update
End With
End Sub

Please refer the below code.
rv = “Are you 56' taller ?”
If I pass 20 fields ie, until [rv = “ Are you 56' taller ? "].
It’s not working because ‘ – apostrophe is used to comment in QTP
How to handle ' ( apostrophe ) in Xpath using QTP ?
Code Snippet:
rv = Replace (rv,"'", "\'")
rv = LEFT(rv,50)
If SVAL = "Yes" Then
Set oobj = Browser("xyz").Page("abc").WebElement("xpath:=//div[contains(text(),'"& rv &"')]/../..//label[starts-with(text(),'Yes')]")
oobj.Click
oobj.Click
i = i+1
End If
I really appreciate your reply.
Try with the character code chr(39) for apostrophe as shown below:
"Are you 56" & chr(39) & " taller ?"
As others mentioned this is not because ' is a comment in vbscript (not just QTP) but because you're ending the string too early.
You use single quotes for the string to compare to in the XPath and then the apostrophe closes the string too early. You should instead use regular quotes there too so that the apostrophe doesn't end the string too early.
In order to get a double quote in a string in VBScript write it twice "Like ""this"" for example".
So your XPath should look like this:
"//div[contains(text(),""Are you 56' taller ?"")]"
Rather than this:
"//div[contains(text(),'Are you 56' taller ?')]"
Or using your example:
Browser("xyz").Page("abc").WebElement("xpath:=//div[contains(text(),"""& rv &""")]/../..//label[starts-with(text(),'Yes')]")
(Note this has been tested and works)
Use ' rather than (') so that the string can be properly processed.

This has nothing to do with the ' being the comment character. This is normal working code:
Msgbox "'I love deadlines. I like the whooshing sound they make as they fly by.' Douglas Adams"
Your code results into an error because some characters needs to be escaped like <, >, & and your infamous '. To enter the line above correctly into an XML tag you need to do this:
htmlEscaped = "'I love deadlines. I like the whooshing sound they make as they fly by.&apos Douglas Adams"
Here you can find an overview to a set of the most common characters that needs escaping (while this is not totally true: if you are using Unicode/UTF-8 encoding, some characters will parse just fine).
Unfortunately VBScript does not have a native function that escapes HTML like the Escape function for urls. Only if you are on ASP Server, you can use Server.HtmlEncode but that is not the case with you
To generalize html escaping (treath everything as special except for the most commons) you can use a script like this:
Function HTMLEncode(ByVal sVal)
sReturn = ""
If ((TypeName(sVal)="String") And (Not IsNull(sVal)) And (sVal<>"")) Then
For i = 1 To Len(sVal)
ch = Mid(sVal, i, 1)
Set oRE = New RegExp : oRE.Pattern = "[ a-zA-Z0-9]"
If (Not oRE.Test(ch)) Then
ch = "&#" & Asc(ch) & ";"
End If
sReturn = sReturn & ch
Set oRE = Nothing
Next
End If
HTMLEncode = sReturn
End Function
It could be improved a bit (you'll notice passing objects into this function will result into an error) and made more specific: the regular expression could be matching more characters. I do also not know the performance of it, regular expressions can be slow if used incorrectly, but it proves as an example.
