Cutting A String Without Half-words?
Aug 8, 2003
I need to display the first c.200 characters of a longer string, for the homepage of a news website. I am using VB.NET. Obviously, cutting exactly 200 chars quite often cuts a word in half, e.g.: "The last five years have seen a radical increase in the volume and complexity of company legislation. The Bahamas has established a Stock Exchange, passed legislation aimed at regu" I need a function that will produce: "The last five years have seen a radical increase in the volume and complexity of company legislation. The Bahamas has established a Stock Exchange, passed legislation aimed at" I can then add "... [More]" or whatever to the end of this string and voila! Is there any way of using regular expressions (regex), substr or something similar to produce this output?

I have a long string that I need to parse into an array of strings that do not exceed 40 characters in length. The tricky part of this for me is making sure that the regex finds the last whitespace before 40 characters to make a clean break between strings since I don't want words cut off.

Builting a calculator. I have a string of two numbers separated by an math sign. Knowing the length of the first number then adding one for the sign will produce the start length of the second number. Trim the original string to get what I need.
dim num(25) as double
dim length,length1 as integer
dim string, string1 as string
length = Len(num(n - 1))
length1 = length + 1

I must input a letter and a number in a text box.. say "A14", and them I want to cut the string into "A" and "14" and then use these, but I do not know how to code this as the next string could be "A1" or "C110" and these change... could I make an if for each one? like an if for when its 2 characters and just cut it in half and then an if when its 3 characters and cut between the 1st and second and so on?

I want to display the first and last characters of any given string entered into a textbox. The strings can be of any length as the user wants (as long as it is one word) I would like to be able to do something like this... "william = will and iam" or "Celtic = Cel and tic"I understand I would have to split or divide the string. How would I go about doing this?

What my program does is load a file (password list), then progressively reads each line of text in the file whilst writing each line to a new file. After X amount of lines have been written, it should start writing the lines of text to a new document until the initial password list has been split into X amount of password lists. The problem I have is that after hours of tweaking, all I can get it to do is write either blank ocuments, or write all of the lines to only one file. I really need it to be able to split into multiple files, preferably at runtime rather than loading a whole text document into the program in a textbox or array then writing it to new files.Below is the source:
Imports System
Imports System.Windows.Forms
Imports System.IO

Im trying to work out what the best way to match 2 strings together, but with a difference.
String1 = "dog cat bird chair book table"
String2 = "the dog chassed the cat around the chair"
No I know I can break string1 up by space character and check if each word appears in string 2, I would prefer to not have to do that.If there some sought of regex that would take a group of words and retrun how many of them matched ?

The following code checks a strings if it contains particular words and if yes it removes them. The problem is that it also removes characters that it shouldn't. For example: If user_input3 contains a word like lo(ok) it would remove the last characters ok. How can i modify the code to remove whole words only?

im working with a receipt layout and trying to divide up a products descriptiontext into 2 lines if its longer then 24 characters.my first solution was something like this:
If Row.Description.Length >= 24 Then
TextToPrint &= Row.Description.Substring(0, 24) & " $100"
TextToPrint &= Row.Description.Substring(24) & vbNewLine

Basically what I'm trying to achieve is to extract all the words within a piece of string and transfer that from one text box to another text box.
An example piece of the string would be
<laugh:894u8438:4434:words>
However the words within the string will never remain constant and the characters before and after will change. Is there anything that will read the string and take a word from the string without it being pre-programmed. The string it is reading from is uploaded from a text file.

I was wondering how would i make a search kind of thing, for example if string1 contains all the words in string2 words. like a search(not just if string1 contains string 2).
it should work something like this:
If string1 is "an apple" and if string2 is "djsjfsfg apple sdfsfssdfs" then string3 would be nothing
BUT
If string1 is "an apple" and if string2 is "djsjfsfg apple sdfsfssdfs an ashdfjdsgfsdgfj" then string3 would be "djsjfsfg apple sdfsfssdfs an ashdfjdsgfsdgfj"

i want to write a code to swap the words in a string.
Input - I like cake
Output - cake I like
To do this it would be great if there is a way to determine the index of each word.Like
1- I
2- like
3- cake
Then I can swap the words.But I have no idea how to do it.Currently I have written the code to count the number of words in a string and to get the average.
Dim str As String = Me.t1.Text
Dim strA() As String = str.Split(" ")
Dim TChrs As Int32
