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 ?

View 7 RepliesCreated for Bill Smith Bill Smith 100 Maple St. Nowhere, MI 49091 Program Information undecided about Your Career Path? I can find the position where "Created for" occurs in the string
VB
Private Function FindText(ByVal strText As String) As String
Return InStr(strText, "Created for")
End Function
I am trying to get the first and last name that occurs right after the "Created for" in that string but I have not found a good way to do so. Essentially there are multiple files in a directory that I am spinning though and changing the name of the files to match the name in the file.
I have a textbox which has about 120 lines of text but this can vary. I want to search for an array of words, like Boeing, Airbus, Saab etc there might be 3 options there might be 5 options in this array that i'm looking for. My question is how can I search the textbox and highlight all these words? Similar to (Control + F) in IE8. I've looked at InStr but am unsure if this is what I'm after as it does not seem to work for me.
View 4 Repliesi 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.

I'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.
View 3 RepliesI have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?

I think I have explained my problem properly..
I'm currently trying to match a word in a string - to a word in an 1 dimensional arrray.
So it does this.
1.Goes into array, gets first word.
2.Looks for that word in the string.
3.If can't find it, go to next word in array.
4.And so forth until it finds it or runs out of words in array.
Problem is the string can be upto 2000 characters long. And the Array with the possible matches can have upto 8000 entries.
So when it runs, if the word begins with 'A' it finds it dead quick as the 'A's are at the top of the array, ordered alphabetically. This is great.
But if the word starts with 'Z' then it takes 4-5 seconds before finding it.
I'm basically using InStr to find the word in the string.
how to check if the user input has a match in my given string
Dim a as string
a = "abc"
if the user input in the textbox "erty" the message box will be shown string not found. if the user input 123abc the message box will be string found
I am making a question and answer game, and I would like to be able to give the user some slack in the answers if they were to misspell a word by a letter or two, like if the answers was Jumps and they type Jump if you did a comparison of them like If string1 = sring2 then do whatever, but obliviously those to string dont match, so it would return false, even though it is the right answer, I came up with this routine to compare two words and if the percentage of the letters are higher then 82 % right it will give you credit for your answer.

View 3 RepliesI need a way to compare multiple strings to a test string and return the string that closely resembles it:
TEST STRING: THE BROWN FOX JUMPED OVER THE RED COW
CHOICE A : THE RED COW JUMPED OVER THE GREEN CHICKEN
CHOICE B : THE RED COW JUMPED OVER THE RED COW
CHOICE C : THE RED FOX JUMPED OVER THE BROWN COW
(If I did this correctly) The closest string to the "TEST STRING" should be "CHOICE C". What is the easiest way to do this?
I plan on implementing this into multiple languages including VB.net, Lua, and JavaScript. At this point, pseudo code is acceptable.

I'm trying to replace a string with another but the problem is that the string is matching some other string partially.
For e.g. -
Dim x as String = "I am Soham"
x = x.Replace("am","xx")
After this replace I would only like the word am to replaced with xx but because my name also contains am its also getting replaced.

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.

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"
Can anyone offer a VB.NET function to extract the first three words from a text string (where spaces are used as dividers between words)?
