View 7 RepliesIm 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 ?
my textbox will shows a random number some time it match, some time it don't. for example: my textbox is displaying "56" and my listview was added "11" instead of "56".here is my code...
TextBox1.Invoke(New Action(Of Integer)(AddressOf UpdateTextBox), CurrentNumber)

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.
I'm trying to loop through all rows, and see if any match what is in the textbox. Would this work?
Code:
Dim dr As Data.DataRow
For Each dr In myQuery.GetMembers()
If UsernameTextBox.Text = dr.Item("mail") Then

I need a way to tell me if a certain word already exists in a multi-lined textbox. Right now I have a multi-lined textbox with some names inside it. After each name I add a newline so all the names are on their own line inside the textbox.I use this code to add names to the textbox, Text Box1. AppendText(ComboBox1.Text + vbCrLf)Then I have been checking if the name exists by doing it this way,[code]The problem is that Ted and Teddy return the same when searching for Ted even if Ted isnt in the textbox at all, I have googled for the last few days and even tried RegularExpressions and still the same results. I think this might be a simple true or false check but I may be wrong... or even a loop or something line by line.
View 5 RepliesI 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 am not a regex guy, so I need a little help, just cant get my head around this...

View 3 RepliesI have a simple string : s:10:"char1";s:2:"13";i:1;a:8:, i'd like to match that 13 from inside " ", in PHP i would do something like :
/s:dd?:"char1";s:dd?:"(.*?)";i:dd?;a:dd?:/i but i'm not good in vb's match methods,so please give me full example how i can match what i need ( it is possible to be multiple matches (2) ).
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.
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 2 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?

View 1 RepliesHeya so im close to be done with this project but unfortunately i still have a couple of questions ill start with the first, imagine this listbox contents:
[Code]...
Now imagine theres a string with : "2-12-2009 | 11:30"How can i delete a listbox item if the string matches the listbox item text after the arrow?It might sound a bit confusing but what im planning to do is to delete a listbox item based on the date of the event and not the date of the alarm.
I have been trying to solve this with no luck. If i have an array Private _msg() As String = {"You have been successfully logged in.", "This message has been sent successfully.", "This message has been posted successfully."} And a string (page source) can LINQ try to find any of the Three elements in the array with out having to use a loop?
