I'm trying to create my own type of spider/search engine thing for fun. I start with a URL, then grab the HTML ...from that I have a REGEX that is supposed to pull out all the links. I figured I would randomly pick one of those and keep going as I save the HTML to my database.[URL]...You can see that I get some real URLS and sometimes I get back some that are not. NOW I return these to a RichTextBox and on the REAL URLs, these get formatted in blue and make a HAND icon when you float over them. This makes me believe that something SOMEWHERE knows that these are good url's. That would be a good thing to tap into so that I could get rid of everything in that box that is not a real URL.
View 1 RepliesI have a textbox for searching a database. When the text changes it runs a functioncFilter() and loads the records. It is set up to search different columns of a database, and it unfortunately only the first record matching is pulled from the database. Example: when the database contains two people (Bob Smith & Bob Smitt) the user can type the name in the search field. However When the user types Bob Smit it only returns Bob Smith and not both names in the database. I want this to act as a filter, dynamically changing the last with each additional letter typed in the search box. Below is my source code,
Public Sub cFilter()
Dim myConnectionstring As String = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & My.Settings.dbLocation & ";Persist Security Info=True;Jet OLEDB:Database Password=BCFAdmin")

I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")

I am to make a program that lets the user save certain data values with a delimiter(":") to a text file(done) Example of data entries [code]Then i am to load those values to a listbox , i was able to do that as well and i include the delimiter when i load the values.Now i am supposed to let the user enter any month/year value for date(mm/yyyy) such as 06/2010 and if any of the entries match the search string then either the program selects those values in the listbox or a popup msgbox is used to show the entries. How the result is displayed is a little irrelevant, but how do i search and atleast select the matching entries in the listbox ? and not just the first instance but all instances of the search string.
View 3 RepliesI 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...

View 9 RepliesRegex in VB2008.I have a file system directory that my code is watching. When a file is placed in that directory my code kicks off a processing application. Based on the filename structure, the code will perform different processes. So I need to match the filename structure specficially to get the correct processes to run on that file.My file name structure is: IK2YYYYMMDD_VV.e;where YYYYMMDD is well, the year, month and day. And VV is a verison number from 00-99 If the new file saved in the directory match this structure then I want a TRUE returned. From a filewatcher I get the filename as an "e.Name" (FileSystemEventArgs) variable. My current code to see if it matches the baseline structure is;
Dim IKPred2Match as New Regex ("^IK2.*\.e$") Dim ValidIKPred2Match as MatchCollection = IKPred2Match.Matches(e.Name)I've tried many different regex match patterns, and just can't seem to find the magic one.

i created a form with a combobox that lists out Assignments ( assignment 1, assignment 2, etc...)......what i need to do is let the user choose an assignment, then the program should look for the matching text file in a folder, ex: user picks assignment 1, and the program will read from assignment1.txt and display the result in a listbox. I have everything except the coding to match what the user chooses and the text file to streamread.

Is there a way that you can export a file from one project directly into another project?
For example, in one project i have a file called authInvalid.vb and i need to export it into another project?
I 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.

I've recently converted some VB 6 code over that used the old non-structured exception handling. I also have some .NET classes that raise custom exception classes. When the code was VB6 I used to expose my .NET classes using COM interop and errors raised from .NET classes were being caught correctly in VB6. Now that everything is .NET the old non-structured exception handling is still there in the converted classes. But now the Err.Number is not reflecting the HResult of the error raised. I wrote a simple little Windows Application form with 2 buttons to simulate the problem. Here is the code snippet:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
On Error GoTo ErrHandler
Err.Description = "Test Error"

If you click Button1 you get the following message:

If you click Button2 you get the following message:

Such as with using Visual Basic 2010. what is an easy simple program to make? Like making your own calculator or whatever.If I even tried fiddling around with Visual Basic 2010, I would change Form1 to the name of the thing that I am creating, along with changing the color of the foreground/background and the color of the text too.But its the command text where I have to add text to make it work too that I would have trouble with. I ain't smart when it comes to stuff like Visual Basic.
