Finding Words Within A String?
Mar 31, 2011
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.

how can i track how many times a specific word appears in a text box then display the number of times found in a message box?
for example if i type this in a textbox: today is really hot, it is not very convinient to be outside, it is better if we go swimming
and i am looking for the word "is" troughout the sentence, it appears 3 times yet I am not sure how to make a code so it does count the times "is" is being found and then display it with a message:
"your word is found 3 times in this sentence"

when i copy code from vb.net code window, and paste it in my richtextbox, the color synthax is as it displays in my vb.net code window.. this i want to keep when finding and replacing words. i have the following code to find and replace,
RichTextBox1.Text = RichTextBox1.Text.Replace("Private Sub", "<font color=blue>Private Sub</font>")
but the color syntax of the richtextbox code is lost, looks like a textbox's text.. how do i replace the words and keep the synthax coloring?

I've got an issue with a program I am writing. The specific issue is replacing characters in a parent string by finding, and matching, specific characters within it that are parsed from an external xml file. It's for a chat-like client.Here's the 2 classes I am using to pull the emote strings, titles, and id from external XML:
Imports System.Text.RegularExpressions
Imports System.Xml.Serialization
Public Class emote

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 ?

I have a somewhat unique problem that I have looked for an answer to and continually hit brick walls. The problem is this. I'm using vb.net to read a byte array from memory which total 32768 in length, which is converted to a string. The memory is the active console chunk in the game Call of Duty 4.

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?

TextToPrint &= Row.Description.Substring(0, 24) & " $100"

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

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?

My problem seems simple but I can't find an answer for it.I need to be able to pull a phone number (string) from an entire string. example: "My phone number is (xxx) xxx-xxxx, call me as soon as possible."
Its obvious to me that the phone number should be able to change depending on who you are talking too. So the question becomes, how do i search for the phone number's format within the above string?
