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 a programming student and a newbie in forums. How can I search for a data in listview from fist form using my second form?For example, I entered 7 entries to my listview, and when I press "Search in listview" button, the second form will open.(My first form contains the listview table and a button named "Search in listview", while the second form contains a textbox which I'll type what I want to search,for example the ID Number, and a button named "Search".)To shorten my code, I like to use from the System.IO Namespace.Is it possible to use System.IO? How? It is frustrating that I can't even find it in Google.

View 3 Replies1. I have a multiline texbox and want to know if there is a way to search for a text in the textbox... The user should be able to input a search string and click a button to search all the entries of the string in it, just like ctrl+f
2. Is there anyway to make the textbox 'read only'? The textbox is populated by application itself, with some logs.. The only reason I chose textbox was because, I can't select an item and copy it from label..
Also, can a textbox include formatting, such as making some text bold, underlined etc?..
I'm working on an application that will look through an XML file and match strings. However, some of the text in the XML that I'm searching is Cut with an *. I'm trying to search through model numbers, and say I'm searching "RGI6400GB", and the entry in the XML is "RGI6*". Is there any way to search if there's an * in the text and have it able to search like that? Some also have the ending of the model, like so; "*GB".
View 18 RepliesI tried different methods like FindItemWithText, but it will not work. My challenge is that I have a textbox (txtSok) for the search word, and a new ListView (frmTelefon) that I will populate with the result from my search. The search routine are using data from another ListViewItem on another form (frmOPS).
I would like to have the search done by using the TextChanged on txtSok. My frmOPS have 5 columns, but the search is going to look for items similar to txtSok.Text in column 2. From the result of the search, I will populate frmTelefon with the Add method in three columns (name, address and phonenumber).
I have been searching all morning for a sample showing a simple "find" example for an ASP.NET Webform, where a "find" button is used to find a string in a Textbox, and then Highlight it, like Word does. The following VB6 code worked perfectly, but I couldn't find .Selstart or .SelLength properties in the Text property of the ASP.NET textbox.
'find the first instance
Private Sub Command14_Click()
Command36.Visible = True
[Code]...
Is there a way to Select the Length and Start of the string in ASP.NET. The Winforms code is very similar to the VB6 code, so maybe I'm just missing something simple.

View 1 RepliesI have a form where a number of textboxes are programmatically created within a flowLayoutPanel and named by adding together 2 strings.
With the click of another button i hope to have all the values entered into these text boxes stored in a text file. However, i cant seem to find a way to add strings together to allow me to retrieve the values entered within the text boxes created.

View 1 RepliesI have a dataGridView and a textbox on a form. I want to be able to search through the dataGridView and sort it compared to the string in the text box. Ex: I type "acv" in the text box and all strings containing "acv" are sorted to the top. I'm accomplishing this with a bunch of gymnastics involving datatable.select and some clearing and filling but it's ugly and slow.

I have 2 forms. The first form has a label on it. The second form has a combo box, a text box, and a button on it. In the second form, when I select the label name that I want to edit, I type in what I want to change the label name to in the textbox and I click the button. Now this goes through flawlessly except I want the combobox item to change to the NEW label name. I've been able to do that but when I close the form in run-time and open it up again, the previous label name appears once again. Is it possible to make the combobox add the new label name and KEEP it in its collection?
View 9 RepliesI have 10 forms and say 5 text box's on each one so a total of 50 of these text box's. But the program is only using one of these forms only (user selects the 1 Form out of the 10) so I was wondering can these forms Share the input text box's? I am thinking NO, if so then the only thing I can do is just use 5 shared variables that all the forms can utilize.
View 2 RepliesI'm writing a .NET CF (VBNET 2008 3.5 SP1) application, which has one master form, and it dynamically loads specific UserControls based on menu click, in a sort of framework idea.

I have cooked up my first iteration of a code generator which creates the basic Entity models from a SQL Database Schema. Currently, It will scan a SQL Db Schema, and create .vb code files complete with private members and Public property declarations for every User table in the Database. My next step is having it add the basic CRUD procedures as well. Are we mere mortals able to access whatever technology allows the Partial class files created by vs to be hidden/Linked to their "parent" files, such as the Partial Class files for Windows forms or any other designer-generated control? My thinking is that it would be handy to be able to re-generate code files from the database if necessary to reflect changes in the schema, without overwriting any other properties or methods added to a class in addition to those derived from the database. SO I am hoing I can have the Auto-generated output go to a Partial Class file, and then use a regular class file of the same name for the rest of the code. My Concern is the multiplicity of files that might result, so I was hoping it is possible to "tuck them in" to the parent code file in the Class View.
