My scenario is i have a multiline textbox with multiple values e.g. below:
firstvalue = secondvalue
anothervalue = thisvalue
i am looking for a quick and easy scenario to flip the value e.g. below:
secondvalue = firstvalue
thisvalue = anothervalue
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

In my windows form I have an empty datagridview that contains strings loaded from a csvfile. The datagridview has no initial column collection. There are four columns in the csv file. In the csv file, columns 1 and 2 have values of true orfalse. So far I am able to load the text perfectly.
What I want to do is change the strings "true" or "false" into an image in my resources (a pretty green checkmark and a red x).
I would like to leave the csv file text as it is, and then change the columns dynamically.
Then, when I save the information back to the csv file, the images must be converted to text strings to accomodate the csv.

View 2 RepliesLet's say I have a textfile which contains paragraphs. Some of the paragraphs start with * or a > character. How do I index the words that start with these characters?
Example:
[code...]
[Code]...
For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.
I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.

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 was unable to implement a multiline label or a transparent multiline textbox. So ive come up with the long way.I have paragraph of words (approx 100) that changes on a click. i want to split the paragraph into blocks of 20 and create 5 strings.

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:

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.
Len gives # of chars in a string in VBScript but I'm trying to find out how to get a # of words, instead.sub fred john_val=window.document.alice.john.value john_len=len(john_val) msgbox "john=" +cstr(john_len) end sub

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"
