What i want to do is take particular values from a list of strings and store them into variables for that particular index. Com317,subject,1,20,M,year1the example is what is contained in each index of the list of strings. I want to select the 1 and the 20 from this list and store them into 2 variables. Been trying to do this with a for each loop but I'm not sure how i can single out these 2 values

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)?
View 11 RepliesI have a number of classes that all implement the same interface. e.g.
Public Class IncidentAsset
Implements IModelWithIdentity
Private _assetId As Int16
Private _otherAsset As String
Private _asset As Asset

Is there a better way of doing this in VB.NET using .NET 2.0?
I have a text box with a list of entries for example:
Reference 1
Reference 2
Reference 3
[Code]....
I plan to read the string back into a the textbox later using the split() method and assign each to string to an array.
I'm using String.Join to attempt to turn an array list into a string that is comma separated, such as "1,2,3,4". I can't seem to get the syntax working.
Here's what I'm trying:
Dim aryTest As New ArrayList()
aryTest.Add("1")
aryTest.Add("2")
aryTest.Add("3")
[CODE]...
How can I go about doing this properly?
How can I find words like and, or, to, a, no, with, for etc. in a sentence using VB.NET and remove them. Also where can I find all words list like above.
View 4 RepliesI'm having a little trouble with this... I have a Session variable which contains a string of comma separated ID's which needs to be passed to a stored procedure but if it is more than 8000 characters, it needs to be split into more comma separated strings. For example;
[Code]...
I have 4 string lists as follows
Dim input_list As New List(Of String) Dim input_POS As New List(Of String) Dim trigger_list As New List(Of String) Dim trigger_POS As New List(Of String)
I want to compare the contents of the input list (containing words (e.g., want, the) etc. to the ones of the trigger list (containign again words) and if a same entry (i.e. word) get the POS for both input word and trigger word from the relevant lists and put them into a property list. For example
input list (want, the, right)trigger list(want, there, wait)input list POS (verb, article, adjective)trigger list POS (verb, pronoun, verb)
Output property list (want:verb, want:verb) (only want is common between input and trigger list). Then I need to conduct a test between the two property items for similarites. If they are exactly the same, the code should output a confirmation "i.e., Yes" into a textbox. If not the code should output a "No" plus the contents of the property list into a textbox.
I am pretty good with perl regular expressions but evidently I am at a loss on why this doesn't work.The code below stores "Person Test" in output variable.
im output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)", RegexOptions.Singleline)
output = re.Replace(userName, "$2 $1")
So why doesn't the following code store "#Test##Person#" in output variable.
Dim output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)")
For Each Match As Match In re.Matches(userName)
output &= "#" & Match.ToString & "#"

I currently have a list of words in a text file sorted in to alphabetical order and put into lower case, but I would like to be able to also display the line numbers on which these words are associated with.. but only one instance of.
For example,
"This is a random text
file that I
have just made
up this second"
[Code].....
As you can see above, I would like to show that "this" for example appears on line 1 and 4. Hopefully tabbed so that it keeps a nice look to it.
I have a string like
human, roti, makan, ghar, house, language, english, india, US, master, teacher, html, code, asp, jsp
i need code for find the input string.
These is the content of my txt file which is saved in D drive in my pc abc,1,2,3..I tried the flowing but it didn't work:[code]I am getting error on this line.. data = line.Split(","c)...it says this line isn't in use anymore or something and that I rather use LineInput but thats asks for filenumber and i don't know what that is. I am sorry but I am a complete beginner. what else can I try? [code]ok that error is gone now but now if I want to add these values to a list box..how can i do that?
View 1 RepliesI need a regular expression that can validate that a string is an alphanumeric comma delimited string.
Examples:
123, 4A67, GGG, 767 would be valid.
12333, 78787&*, GH778 would be invalid
fghkjhfdg8797< would be invalid
This is what I have so far, but isn't quite right: ^(?=.*[a-zA-Z0-9][,]).*$
Hi I've run into a really annoying problem, I'm trying to set the value of a hidden input to a comma seperated list taken from a database but in pure CSV format it won't set the value.The input tag and ul tag looks like this (I am aware of asp:hiddenfield and it's value property but I'm not using it as I still have this issue):
[code]...
This will populate the li tags but will not populate the value for the input, I've tried using the replace function on the list for the value but it only works if I remove the commas or put other characters infront of them. I've also tried replacing it with the HTML code for a comma but just prints the HTML code out.
Is there a built-in function in VB.NET which would take an array of strings and output a string of comma separated items?
Example: function( { "Sam","Jane","Bobby"} ) --> "Sam, Jane, Bobby"
I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

Now it seems like a really simple question and I may just be being thick, but what I'm trying to achieve is basically print an array to screen in the following format: Item 1, Item 2, Item 3, Item 4 Although I say to screen, as that was the best way I could describe it, I'm actually writing it to the page inside some Javascript. The way I'm currently going about writing it out is as follows:

I'm using a program see here: Visual Basic Regular Expression Question. I enter letters and the program returns all possible combinations from list. I want change this line of code...
Dim result = fruits.Where(Function(fruit) Not fruit.Except(letters).Any())
If I have this list:
Dim fruit as List(Of string) from {"apple","orange","pear","banana"}
And I input "p a p l e r" then it would return "apple" and "pear", but if I enter "a p l e r" then it would return just "pear". The idea is to return all words, which can be made of entered letters without duplicating any single letter. How to optimize this Linq code?
i would like to split my data from string and put it into integer and invidual string as sample below:
this is the data i want:
Private total() As Integer = {10, 6, 2, 1} 'here consider length = 4
Private towns() As String = {"A", "B", "C", "D"} 'here consider length = 4
below is the data i get it now:
Dim total2 as string = "10,6,1" 'here consider length = 1
Dim towns2 as string = ""A,"B","C","D"" 'here consider length = 1
how to split the total2 and towns2 i get and split into total() and towns() i want.
it is i need to write a for loop to split the string by comma?
I have the following code which takes input from a text box and then writes everything to a file...
[code]...
now because it's not convenient for me to type one by one the words in the text box...what i thought i could do is to find a way to feed a list of the words and then choose with the arrow keys which word it should be written to the specific file.
Dim FILE_NAME As String = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) & " ext.txt"
Dim i As Integer

I am trying to get a random word in VB and was wondering if it was possible to do this through the internet some how? For example If there was a website that literally just contains random words (anything over 100 will do) and I could just select a random word from it? I can create random letters and numbers but I want a word that would be in a dictionary.
View 5 RepliesThe code below replaces if it finds a given string from the list of contractions with its equivelant from the list of word-contractions. E.g., if it finds 'll it will replace it with Will. The code words but whtn it comes to let's it will replace it with let is.

I want to pass a comma delemited list of values as a parameter to a query I'm building using the designer in Visual Studio 2008 based on some strongly typed DAL tutorials I was going through. The query is going against a DB2 database. Here's what I want to do:
select * from prices where customer in(?)
It works fine win I pass in 123456 as ?But fails when I pass in '123456' (it is a char field so I don't know why this doesn't work; it must be adding these behind the scenes) or 123456, 123457 or '123456', '123457' I'm adding this page to a portal where all the data access is being done based on the DAL designer model with a BLL that calls it so I wanted to do it this way for consistency.
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 used a built in function to create comma separated string using List easily.(It is not split and join but new function) I'm not able to recollect or find it. If some one knows about it and uses it please post a link to that. Framework - .net 2.0
(It is not Join or split - I know about this, .net has new built in function to create CSV format)
Check Jacob G Answer below for what i was looking for let me know your thoughts on it compared to join ;)
