I want to add a function to remove all extra spaces from the text written in the text boxes in my php code. How to do it?
If you don't care about word separator spaces and want really serial string:
$string = 'forexample string with space and more';
$no_space = str_replace(" ","",$string);

How to prevent line feeds (vbLf) and carriage returns (vbCr) in a text box that should only be one line, in a text file? It can happen that these carriage return characters and these new line characters are present (for example during a copy and paste) in the body of the text and thus make the reading of the file impossible. This has happened to me before, and I think I need to set up a check for the presence of these characters and thus warn the user to check his line before any recording. Thank you in advance. Claude.
Replace the CR and LF with nothing?
textBoxWithCrLf.Text.Replace(vbCr, "").Replace(vbLf, "")
Note, this doesn't modify the contents of the textbox, it generates a new string with no CRLF, so you'd use it like:
somefilewriter.SomeWriteStringMethod( textBoxWithCrLf.Text.Replace(vbCr, "").Replace(vbLf, "") )
How can I remove all URL in the text via openrefine? Is there any transform code for that? My data have many URL links different from each other in the texts. And I want to remove these links.
For example my data have like that text in the cells
"put returns between paragraphs for linebreak add 2 spaces at end italic or bold indent code by 4 spaces backtick escapes like _so_ quote by placing > at start of line to http://foo.com/"
And I want to delete only URL links in the cells. After removing it should be;
"put returns between paragraphs for linebreak add 2 spaces at end italic or bold indent code by 4 spaces backtick escapes like _so_ quote by placing > at start of line to"
This transformation should do the trick :
value.replace(/(http:\/\/www\.|https:\/\/www\.|http:\/\/|https:\/\/)?[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:[0-9]{1,5})?(\/.*)?/, '')
I want to convert any special characters entered in infopath textbox into under score.Using the translate function, in the below example I am able to replace the space with under score
translate(fileName, " ","_")
Since translate function takes only three parameters then how can we check all the special characters? My target is if any special characters including space is entered into the text box it should automatically replace these special characters with under score ("_")
what if you reverse it. If it is not A-Z, then convert it
or try this:
translate(field1, "!##%^&", "_")
I have a text file which contains about 60 lines. I would like to parse out all the text from that file and display in a window. The text file contains words that are separated by an underscore. I would like to use regular expression to solve this problem.
Update:
This is my code as of now. I am trying to read "filename" in my code.
Dim filename = "D:\databases.txt"
Dim regexpression As String = "/^[^_]*_([^_]*)\w/"
I know I don't have much done here anyway but I am trying to learn VB on my own and have gotten stuck here.
Please feel free to suggest what I should be doing instead.
Something like this:
TextBox1.Lines = IO.File.ReadAllLines("fileName")
To remove underscores:
TextBox1.Lines = IO.File.ReadAllLines("fileName").Replace("_", String.Empty)
If you also need other special characters removed, you can use Regex.Replace:
Remove special characters from a string
Also on MSDN:
How to: Strip Invalid Characters from a String
Or the old school way - loop through all characters, and filter only those you need:

I need to check if a string from a word document contains a paragraph character. I want to only extract the text without the paragraph character. Is There a constant for the paragraph character? I tried checking for vbnewLine and vbCrLF, but these didn't work.
Have a look at the wikipedia article on newlines.
In total there are 3 characters indicating a new line (in some context), and sometimes they are used in combinations.
I think it does not matter which ones Word uses and which ones it doesn't; You want them all gone.
So, I'd say run through all characters and remove all LF, CR and RS instances, or replace them by spaces (whilst avoiding double spaces)
