The problem that I'm facing is that I have an entire column that has text separated by _ that contains pixel size that I want to be able to extract but currently can't. For example:
A
Example_Number_320x50_fifty_five
Example_Number_One_300x250_hundred
Example_Number_two_fifty_728x49
I have tried using Substitute function to grab the numbers which works but only grabs the numbers when I need something like: 320x50 instead I'm getting 0, as I'm not sure how to exactly extract something like this. If it was consistent I could easily do LEFT or RIGHT formula's to grab it but as you can see the data varies.
The result that I'm looking for is something along the lines of:
A | B
Example_Number_320x50_fifty_five | 320x50
Example_Number_One_300x250_hundred | 300x200
Example_Number_two_fifty_728x49 | 728x49
Any help would be much appreciated! If any further clarification is needed please let me know and I'll try to explain as best as I can!

I would probably use a Regular Expressions UDF to accomplish this.
First, open up the VBE by pressing Alt + F11.
Right-Click on VBAProject > Insert > Module
Then you can paste the following code in your module:
Option Explicit
Public Function getPixelDim(RawTextValue As String) As String
With CreateObject("VBScript.RegExp")
.Pattern = "\d+x\d+"
If .Test(RawTextValue) Then
getPixelDim = .Execute(RawTextValue)(0)
End If
End With
End Function
Back to your worksheet, you would use the following formula:
=getPixelDim(A1)
Looking at the pattern \d+x\d+, an escaped d (\d) refers to any digit, a + means one or more of \d, and the x is just a literal letter x. This is the pattern you want to capture as your function's return value.
Gosh, K Davis was just so fast! Here's an alternate method with similar concept.
Create a module and create a user defined function like so.
Public Function GetPixels(mycell As Range) As String
Dim Splitter As Variant
Dim ReturnValue As String
Splitter = Split(mycell.Text, "_")
For i = 0 To UBound(Splitter)
If IsNumeric(Mid(Splitter(i), 1, 1)) Then
ReturnValue = Splitter(i)
Exit For
End If
Next
GetPixels = ReturnValue
End Function
In your excel sheet, type in B1 the formula =GetPixels(A1) and you will get 320x50.
How do you create a user defined function?

Use the user defined function
Note how the user defined function is called.
When I finally had figured out that I can use my own language with Range.FormulaLocal in stead of Range.Formula I was very excited!
The possibilities are endless. But, I am encountering a problem with textstrings in formulas.
This code works just fine:
Range("I5").FormulaLocal = "=ALS(A5=1;H5;0)"
But these codelines are not working:
Range("I5").FormulaLocal = "=ALS(A5="x";H5;0)"
Range("I6").FormulaLocal = "=ALS.FOUT(VERT.ZOEKEN(A2;'betaaltermijnen.xlsx'!tabel;3;ONWAAR);"")
Could somebody help me?
You're accidentally ending your strings early...
First line:
If you have a variable x which you want to include in the string, then use &
Range("I5").FormulaLocal = "=ALS(A5=" & x & ";H5;0)"
If instead you're trying to have the string "x" then you must use an additional quotation mark before each in-string quotation mark. This is called an escape character.
Range("I5").FormulaLocal = "=ALS(A5=""x"";H5;0)"
This way, when VBA sees "", it treats it as the start or end of a quote within a string
By the same reasoning, your second line becomes
Range("I6").FormulaLocal = _
"=ALS.FOUT(VERT.ZOEKEN(A2;'betaaltermijnen.xlsx'!tabel;3;ONWAAR);"" "") "
Where I've used the _ underscore to continue the line without it getting too long, because the last 6 characters are the important bit!
I'm trying to extract my parameters from my SQL query to build my xml for an SSRS report. I want to be able to copy/paste my SQL into Excel, look through the code and find all instances of '#' and the appropriate parameter attached to it. These paramaters will ultimately be copied and pasted to another sheet for further use. So for example:
where DateField between #FromDate and #ToDate
and (BalanceFiled between #BalanceFrom and #BalanceTo
OR BalancdField = #BalanceFrom)
I know I can use Instr to find the starting position of the first '#' in a line but how then do I go about extracting the rest of the parameter name (which varies) and also, in the first two lines of the example, finding the second parameter and extracting it's variable lenght? I've also tried using the .Find method which I've been able to copy the whole line over but not just the parameters.
I might approach this problem like so:
Remove characters that are not surrounded by spaces, but do not
belong. In your example, the parentheses need to be removed.
Split the text using the space as a delimiter.
For each element in the split array, check the first character.
If it is "#", then the parameter is found, and it is the entire value in that part of the array.
My user-defined function looks something like this:
Public Function GetParameters(ByRef rsSQL As String) As String
Dim sWords() As String
Dim s As Variant
Dim sResult As String
'remove parentheses and split at space
sWords = Split(Replace(Replace(rsSQL, ")", ""), "(", ""), " ")
'find parameters
For Each s In sWords
If Left$(s, 1) = "#" Then
sResult = sResult & s & ", "
End If
Next s
'remove extra comma from list
If sResult <> "" Then
sResult = Left$(sResult, Len(sResult) - 2)
End If
GetParameters = sResult
End Function

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.
Is there a way to have multiline strings in VB.NET like Python
a = """
multi
line
string
"""
or PHP?
$a = <<<END
multi
line
string
END;
Of course something that is not
"multi" & _
"line
You can use XML Literals to achieve a similar effect:
Imports System.XML
Imports System.XML.Linq
Imports System.Core
Dim s As String = <a>Hello
World</a>.Value
Remember that if you have special characters, you should use a CDATA block:
Dim s As String = <![CDATA[Hello
World & Space]]>.Value
2015 UPDATE:
Multi-line string literals were introduced in Visual Basic 14 (in Visual Studio 2015). The above example can be now written as:
Dim s As String = "Hello
World & Space"
MSDN article isn't updated yet (as of 2015-08-01), so check some answers below for details.
Details are added to the Roslyn New-Language-Features-in-VB-14 Github repository.
VB.Net has no such feature and it will not be coming in Visual Studio 2010. The feature that jirwin is refering is called implicit line continuation. It has to do with removing the _ from a multi-line statement or expression. This does remove the need to terminate a multiline string with _ but there is still no mult-line string literal in VB.
Example for multiline string
Visual Studio 2008
Dim x = "line1" & vbCrlf & _
"line2"
Visual Studio 2010
Dim x = "line1" & vbCrlf &
"line2"
I used this variant:
Dim query As String = <![CDATA[
SELECT
a.QuestionID
FROM
CR_Answers a
INNER JOIN
CR_Class c ON c.ClassID = a.ClassID
INNER JOIN
CR_Questions q ON q.QuestionID = a.QuestionID
WHERE
a.CourseID = 1
AND
c.ActionPlan = 1
AND q.Q_Year = '11/12'
AND q.Q_Term <= (SELECT CurrentTerm FROM CR_Current_Term)
]]>.Value()
it allows < > in the string
Multi-line strings are available since the Visual Studio 2015.
Dim sql As String = "
SELECT ID, Description
FROM inventory
ORDER BY DateAdded
"
You can combine them with string interpolation to maximize usefullness:
Dim primaryKey As String = "ID"
Dim inventoryTable As String = "inventory"
Dim sql As String = $"
SELECT {primaryKey}, Description
FROM {inventoryTable}
ORDER BY DateAdded
"
Note that interpolated strings begin with $ and you need to take care of ", { and } contained inside – convert them into "", {{ or }} respectively.
Here you can see actual syntax highlighting of interpolated parts of the above code example:
If you wonder if their recognition by the Visual Studio editor also works with refactoring (e.g. mass-renaming the variables), then you are right, code refactoring works with these. Not mentioning that they also support IntelliSense, reference counting or code analysis.
Multiline string literals are introduced in Visual Basic 14.0 - https://roslyn.codeplex.com/discussions/571884
You can use then in the VS2015 Preview, out now - http://www.visualstudio.com/en-us/downloads/visual-studio-2015-downloads-vs (note that you can still use VS2015 even when targeting an older version of the .NET framework)
Dim multiline = "multi
line
string"
VB strings are basically now the same as C# verbatim strings - they don't support backslash escape sequences like \n, and they do allow newlines within the string, and you escape the quote symbol with double-quotes ""
this was a really helpful article for me, but nobody mentioned how to concatenate in case you want to send some variables, which is what you need to do 99% of the time.
... <%= variable %> ...
Here's how you do it:
<SQL>
SELECT * FROM MyTable WHERE FirstName='<%= EnteredName %>'
</SQL>.Value
Well, since you seem to be up on your python, may I suggest that you copy your text into python, like:
s="""this is gonna
last quite a
few lines"""
then do a:
for i in s.split('\n'):
print 'mySB.AppendLine("%s")' % i
# mySB.AppendLine("this is gonna")
# mySB.AppendLine("last quite a")
# mySB.AppendLine("few lines")
or
print ' & _ \n'.join(map(lambda s: '"%s"' % s, s.split('\n')))
# "this is gonna" & _
# "last quite a" & _
# "few lines"
then at least you can copy that out and put it in your VB code. Bonus points if you bind a hotkey
(fastest to get with:Autohotkey) to do this for for whatever is in your paste buffer. The same idea works well for a SQL formatter.
Multi-line string literals in vb.net using the XElement class.
Imports System.Xml.Linq
Public Sub Test()
dim sOderBy as string = ""
dim xe as XElement = <SQL>
SELECT * FROM <%= sTableName %>
<ORDER_BY> ORDER BY <%= sOrderBy %></ORDER_BY>
</SQL>
'** conditionally remove a section
if sOrderBy.Length = 0 then xe.<ORDER BY>.Remove
'** convert XElement value to a string
dim sSQL as String = xe.Value
End Sub
To me that is the most annoying thing about VB as a language.
Seriously, i once wrote the string in a file and wrote code something along the lines of:
Dim s as String = file_get_contents("filename.txt")
just so i could test the query directly on SQL server if i need to.
My current method is to use a stored procedure on the SQL Server and just call that so i can pass in parameters to the query, etc
I figured out how to use both <![CDATA[ along with <%= for variables, which allows you to code without worry.
You basically have to terminate the CDATA tags before the VB variable and then re-add it after so the CDATA does not capture the VB code. You need to wrap the entire code block in a tag because you will you have multiple CDATA blocks.
Dim script As String = <code><![CDATA[
<script type="text/javascript">
var URL = ']]><%= domain %><![CDATA[/mypage.html';
</script>]]>
</code>.value
You could (should?) put the string in a resource-file (e.g. "My Project"/Resources) and then get it with
Dim a = My.Resources.Whatever_you_chose
Disclaimer: I love python. It's multi-line strings are only one reason.
But I also do VB.Net, so here's my short-cut for more readable long strings.
Dim lines As String() = {
"Line 1",
"Line 2",
"Line 3"
}
Dim s As String = Join(lines, vbCrLf)
you can use XML for this like
dim vrstr as string = <s>
some words
some words
some
words
</s>
in Visual studio 2010 (VB NET)i try the following and works fine
Dim HtmlSample As String = <anything>what ever you want to type here with multiline strings</anything>
dim Test1 as string =<a>onother multiline example</a>
Available in Visual Basic 14 as part of Visual Studio 2015
https://msdn.microsoft.com/en-us/magazine/dn890368.aspx
But not yet supported by R#. The good news is they will be supported soon! Please vote on Youtrack to notify JetBrains you need them also.
If you need an XML literal in VB.Net with an line code variable, this is how you would do it:
<Tag><%= New XCData(T.Property) %></Tag>
Since this is a readability issue, I have used the following code:
MySql = ""
MySql = MySql & "SELECT myTable.id"
MySql = MySql & " FROM myTable"
MySql = MySql & " WHERE myTable.id_equipment = " & lblId.Text
You can also use System.Text.StringBuilder class in this way:
Dim sValue As New System.Text.StringBuilder
sValue.AppendLine("1st Line")
sValue.AppendLine("2nd Line")
sValue.AppendLine("3rd Line")
Then you get the multiline string using:
sValue.ToString()
Use vbCrLf or vbNewLine. It works with MessageBoxes and many other controls I tested.
Dim str As String
str = "First line" & vbCrLf & "Second line"
MsgBox(str)
str = "First line" & vbNewLine & "Second line"
MsgBox(str)
It will show two identical MessageBoxes with 2 lines.
No, VB.NET does not yet have such a feature. It will be available in the next iteration of VB (visual basic 10) however (link)
if it's like C# (I don't have VB.Net installed) you can prefix a string with #
foo = #"Multiline
String"
this is also useful for things like #"C:\Windows\System32\" - it essentially turns off escaping and turns on multiline.
