How to convert a string literal into a string value - string-literals

hi i want to convert a string literal in to string value, can any one guide me in doing that
for eg i want o convert the following string literal in to stringvalue.
"hello \r\n world"
in to "hello world"

Which language are you trying to accomplish this in?
For example, in C++ you could do:
#include <string>
...
std::string s = "Hello \r\n World";
To create the object as an STL String (assuming by 'String Value' you mean you want to store the string in some form of class?
Your question could really benefit from a bit of clarification.

How to Convert Dictionary to String or StringBuffer in Robot Framework?

I'm trying to convert Dictionary to String for Regex pattern Match
but for this we need string or stringbuffer
any Idea how to do it?
In the BuiltIn library there is the standard keyword Convert To String that you can use for this:
*** Test Cases ***
TC
${dict} Create Dictionary a=1 b=2 c=3
${nested_dict} Create Dictionary first=${dict} second=${dict}
${string} Convert To String ${dict}
${nested} Convert To String ${nested_dict}

Accessing elements of a map when using a variable key in Groovy

I'm trying to replace some characters in a String From a map
Case 1
​map= ['O':'0', 'L':'1', 'Z':'2', 'E':'3']
"Hey".toUpperCase().toCharArray().each{
print map.get(it,it)
}
The result is
HEY
Case 2 : I dont use toCharArray()
"Hey".toUpperCase().each{
print map.get(it,it)
}
The result is like expected
H3Y
So I tried several alternatives when using toCharArray(), and the only way to access the value is to use map."$it"
Why i can only use map."$it" to access my map when using toCharArray() ?
Because you are trying to get a value from a map using a char whilst every key there are String, and they are not equals:
assert !'E'.equals('E' as char)
$it works because it is converted to String:
e = 'E' as char
assert "$e".toString().equals('E')
(Note the toString() is needed, otherwise the comparison will happen between String and GStringImpl which are not equals)

How to get a string from TextIO in sml/ml?

I'm trying to read text from a file in SML. Eventually, I want a list of individual words; however, I'm struggling at how to convert between a TextIO.elem to a string. For example, if I write the following code it returns a TextIO.elem but I don't know how to convert it to a string so that I can concat it with another string
TextIO.input1 inStream
TextIO.elem is just a synonym for char, so you can use the str function to convert it to a string. But as I replied to elsewhere, I suggest using TextIO.inputAll to get a string right away.
Here is a function that takes an instream and delivers all (remaining) words in it:
val words = String.tokens Char.isSpace o TextIO.inputAll
The type of this function is TextIO.instream -> string list.

VB - dll, string character output

I’m trying to obtain data from a dll, but I do not know how to do it.
My code is:
'Function
Public Declare Function SET_XML_PATH Lib "EbmPapstFan.dll" (ByRef ruta As String) As Long
Public Declare Function GET_PRODUCTS Lib "EbmPapstFan.dll" (ByRef ruta As String) As Long
Sub Selec()
Dim ruta As String
Dim Int_A As Long, Int_B
ruta = "C:\ebmpapst\data\AC\"
Int_A = SET_XML_PATH(ruta) 'If Int_A=0 then they aren't mistake
Int_B = GET_PRODUCTS("")
Worksheets("Selec").Range("E2").Value = Int_B 'Nº products
End sub
Results are:
Int_A= 0
Int_B= 18
This isn't a mistake with the path because Int_A is 0. In addition, GET_PRODUCTS gives me the number of products that software has. The manual say that this function also has string character output.
The primary problem is that I don’t know how obtain this other string character output.
vb dll strange output in C#
Both outputs of the declared functions are "Long" and not "String" so there's no way that they're outputting anything except that.
I'd recommend revisiting the manual you refer to, to see exactly how it is documented and what the string value's function call would be.
The 2 function declaratons show long as the return types, however, the string being passed in is going in byRef and not byVal. It is possible that the string value is being returned via that parameter being adjusted inside the call.
More details about the documentation would be helpful.

Replacing regular expression with keycode data

Public ReadOnly Property IsAlphaNumeric(ByVal entry As String) As Boolean
Get
Return New Regex("(?!^[0-9]*$)(?!^[a-zα-ωA-ZΑ-Ω]*$)^([a-zα-ωA-ZΑ-Ω0-9]{6,15})$", RegexOptions.IgnoreCase).IsMatch(entry)
End Get
End Property
This one is pretty good for Greek and English language.
What about all the other languages in the universe?
Should i replace the above code with another function, validating keycode data and text length or what?
I would recommend to use unicode character definitions instead, such as \p{L} for letters and \p{N} for numbers.
You can find documentation on which categories that are recognized at MSDN.
However, I am not sure whether it supports the Klingon alphabet.
This one is brilliant also! Found at a1vbcode.com
Public Function IntlIsAlphaCharacter(sChar As String) As Boolean
IntlIsAlphaCharacter = (Not (UCase(sChar) = LCase(sChar))) Or (sChar = " ")
End Function
The native language of klingons is regex's?
