Using Regex To Search For 4 Letter Words?
Jan 4, 2010
I have a textbox with a large amount of data, but I am trying to extract only the following into an array: only 3 or 4 letter, uppercase words. The goal is to find all stock symbols within a document.
For example, in this post, if I were to type "MSFT", regex would extract MSFT because it is a 4 letter, uppercase word.

Dim TextLine As String

changing the way the site search is done from just search a phrase as one string to searching a phrase "as multiple words" search. For example, if I search "cute puppy" right now, it will search it for "cute puppy" as phrase and won't match just "cute" and "puppy". The way the search is implemented is by passing a search phrase to a Stored Procedure in SQL Server.So now, I need to change to site search so when "cute puppy" is searched, it will search two words.... "cute" and "puppy" instead of just "cute puppy". Below is how the store procedure is implemented
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

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 & "#"
Next

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'm attempting to setup a search function from a string a user types. (ex: "John Doe" or "Doe, John") I was thinking I would use Replace(SearchString, ",", "") to get rid of the commas the user might enter, and then use Split(SearchString, " ") to get all the words into an array. Once they're in the array I would execute a Stored Procedure on each of the terms and build a DataTable with the results.
Below is what I'm wanting to use for executing my stored procedure.
oCommand = DataAccess.GetSQLCommand("MyStoredProcedure", CommandType.StoredProcedure, SourceServer.ConnectionLocal)
oCommand.Parameters.AddWithValue("@MySearchString", SearchString)
[Code]....
Now I'm thinking the "SearchString" I will assign while looping through my array of words... but this doesn't seem like the right way to do this. Maybe it is but I don't know how to append my next result to the previous DataTable either.

I have an array of words that must be sorted alpabetically using selection sort, I must then be able to search the array with a binary search. I just can't get my head around how you would go about doing it. I know that the words must be first sorted into alphabetical order. Here is the code for selection sort with numbers:
Dim pass As Integer
Dim count As Integer
Dim minmax As Integer
Dim temp As Integer
[code]....
How would you apply that to an array of strings?

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.

I'm trying to make a program (in VB 2008 Express Edition) that will take text (from a textbox) and then switch the letters (say a->f and A->F) and will put the result into a second textbox when I click a button. How do I code the program so that it will search through the textbox and find all of a certain letter (say a) and replace it, then search for the next letters (say b-z) and replace them?

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

This is what comes out: "A first occurs in position -1". Everything comes out except the position is always displayed as -1.
