VS 2010 String Matching?
Jul 22, 2011In javascript I know you can put for instance if date= "2010"* which would do the if for the string if it starts with 2010 but it doesn't matter what comes after that.

View 4 RepliesI want to check each of the strings in an array (currently in a hashtable, but that shouldn't necessarily matter right?) with the user's input, if the words in each of them match. This might have sounded a little tricky so let me elaborate.
Problem: Comparing an input string with a collection of strings, and know which string in the collection matches the input string the most - based on words. What I'm trying to do here is a chatbot that works with keywords. For example, in the bot script, you could find "HOW ARE YOU" and the response "I am fine." If the user then sends input to this bot, it could look like this: [Code] This may not sound like a tricky thing, but the tricky part comes when I want to know which of the strings (e.g. "HOW ARE YOU") match the input string the most, based on the words.

In this exmample textData is a string of text and alpha is a single letter a through z or A through Z. I don't need the criteria to be case sensitive, but I do need only the first letter of textData to match alpha. I have tested the LIKE comparator and it does not return all records that begin with alpha.
1 within each section of a SplitContainer. The left hand side will be for inputing text that is copied/pasted from a word, excell, or text file.The right hand side would be for my output. What I would like it to do is return just the rows from the left hand side that contain a match to any one of the predifined strings. This will be used to search large lists of company names and circuit IDs and return the rows with matching namesSo far I have the form created, the Splitcontainer in place along with the richtextbox on each side and a submit button at the bottom.
View 12 RepliesI have to scan through documents. Excell, Word, txt, ect looking for company names that match a pre-difined list of companies.I then email the companies some specifics in regards to that doc.The problem I have been having recently is that the list of companies keeps growing and I am starting to miss some more than I used to.What I would like to build is a tiny app that has 2 Text boxes.1 on the left for input (where I would copy/paste) the document text I receive.and one on the right for the output where it will highlight any line that contains the name of any of the pre-defined companies.
I started toying with the idea and so far I have form with a SplitContainer. Within that SplitContainer each side has a TextBox... Below the Textbox on the left hand side splitcontainer I have a submit button with no actions currently assigned to it.
I have a list of names of players and their names in some game. Now an administrator of that game might want to contact one of the players by sending him a message. He does that by writing a command that basically has the format "tell <player> <message>", where <player> is the name of the player.The problem is simple: player names might be quite complicated and long (it's their screen name not their real name), and it would take the admin quite some time to find out how to spell the name exactly and he will probably make a few mistakes. Basically, having the admin type out the exact name is not practical.So I am trying to implement a 'fuzzy logic' search (is that even the correct term?) but with a twist, I guess.The idea is that the admin can type just part of the name and is even allowed to make a couple mistakes. For example, suppose a player has a screen name of "Mr.Smith34", then the admin should be able to type, for example.[code]
The problem now is that there can be absolutely no ambiguity in which player is meant. Instead of sending a message (which is quite harmless) the admin should also be able to 'kick' or ban someone from a game server, banning them from ever playing there again. Obviously, the admin should then not accidently ban a player named "Mrs.Smith" when he meant "Mr.Smith"! My solution (unless someone else can come up with something better) is to just not allow the command if there are multiple matches. If the admin searches for 'smith' and there are multiple names that are similar to 'smith' (maybe even 'sith' or similar) then I disregard that search and tell the admin he needs to try again with a more specific name.(If all else fails he can always look up the ID of the player and use that, which should be foolproof as long as the admin doesn't make a mistake and picks the wrong ID..., but that is even more work it does not have preference).But this brings further problems. The example I just gave might be good: suppose there's a player "Mr.Smith" and a player "Sith". If the admin searches for 'Smith' then there should be no question who he meant (Mr.Smith), but I am sure any fuzzy logic implementation would count Sith as a very close match... Another thing is that my solution of only allowing the search if there is just a single match probably wouldn't work. I have never used fuzzy logic searching before, but I can imagine some names being marked as 'slightly similar' even when they are completely different ('smi' might match 'smith', but also 'ims' perhaps, in which case it would possibly match a whole new range of names), even though 'for humans' it is clear which result is meant.
I am assuming any fuzzy search would return the matches and rate them according to how similar they are to the search term. Perhaps I can choose some kind of cut-off value, where any matches that are less than 30% similar (I've no idea just guessing here) are assumed not equal whereas higher ranked matches are assumed a possible match. Perhaps this makes it easier (perhaps harder, I dunno), but I forgot to mention that the search term cannot contain any spaces. Player screen names can contain spaces though. I am thinking to just strip out the spaces of each name before starting the search, but perhaps there are better solutions in combination with fuzzy searching...
I'm running a program and reading the command line output, and, when I compare the output I get with the actual output of the program, I'm quite shocked to see that it doesn't actually match up and, sometimes, the text won't even display at all until after the entire process is done [despite using the Asynchronous methods].I'm not sure if I'm doing anything wrong here...I can post the code [it's a rough translation from VB.net to C#, which I can easily translate back], but is there anything I can actually do to fix this issue
View 5 RepliesI can't figure out the syntax for searching an array of stored words for a string matching an input string. I understand the pseudocode of it, but I'm tripping up over what variables I need to put where, and how they should be formatted. More than happy to provide more details should anyone request them.

I am using vb.net to parse my own basic scripting language, sample below. I am a bit stuck trying to deal with the 2 separate types of nested brackets.
Assuming name = Sam
Assuming timeFormat = hh:mm:ss
Assuming time() is a function that takes a format string but
has a default value and returns a string.
[code]....
I could in theory change the syntax of the script completely but I would rather not. It is designed like this to enable strings without quotes because it will be included in an XML file and quotes in that context were getting messy and very prone to errors and readability issues. If this fails I could redesign using something other than quotes to mark out strings but I would rather use this method.
Preferably, unless there is some other way I am not aware of, I would like to do this using regex. I am aware that the standard regex is not really capable of this but I believe this is possible using MatchEvaluators in vb.net and some form of recursion based replacing. However I have not been able to get my head around it for the last day or so, possibly because it is hugely difficult, possibly because I am ill, or possibly because I am plain thick. I do have the following regex for parts of it.
Detecting the parentheses: (w*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))
Please help solve the problem.First, let me describe what I want to feature me of the problem.I Function SPLITyahoomessage () to intercept the statement, the statement should not be captured through the interception.Here I use x () array to the breakpoint.But I say there are two windows in the pm 10:10 swept the first window of the sentence recorded in x (0) in Then x (1) record from the second window of the sentence.Here is a very strange x (0) memory from the sentence.Here are the features I want to achieve
It will break out in the interception of sentence in accordance with the procedure. But the second window x (1) I gradually during the scan, I found that x (1) had memorized the sentence re-enter
SPLITyahoomessage () in the time x (1) into nothing.

I need an extremely simple regex pattern that matches anything within square brackets [].
Example:
This is a [test] text with [some] [examples].Required results: [test], [some], [examples].I don't want to get rid of the brackets, they should be included in the result (that should make it easier, right?)
If possible I'd like to exlude results that have whitespace in them, so things like [this string] should not be matched. If that gets too hard (probably not, but hey I can't even manage this :S) then I don't really mind, I can always check if the result contains whitespace myself.
I tried a lot of examples I could find online and ones that I could think of myself but none work. Note: I've been testing with the Visual Studio Find dialog (checking to use regular expressions obviously), maybe that's where the problem lies, because I don't really understand why some of these don't work...
Anyway, first thing I tried was simple: match the two brackets and one or more characters in between (that should be a +, right?)

View 13 RepliesI am trying to search for a particular string on a *.txt file, while i can do this i want to be able to do it without having to type the exact string.
For example:
if i search "string" i find "string" but not "String" the big letter wrecks the search... anyone knows how to do a search like this?
And i want also to give me an incremental search while i am typing on a list box.
For example:
if i type "s" it appears, sangoku,slb, siemens,sentence,...., string,...
on the listbox. These are words that exist on the *.txt file i am reading.
if i type "st" it appears only string and any other word that starts with "st"
it would be an automatic search without having to press enter, or any search button. Just by pressing the keyboard on the letter we wanted the search would be made.

In VB6 datacombobox there was a property that you could set that filtered the item list as you typed in the combo box (extended matching I think it was called) so that as the user typed more characters in the box the filtering progressively narrowed down the number of items in the list.The .net control does not seem to have this facility, or does it?Do we have to programatically do it now?
