How To Remove A Listboxitem Based On Partial String Match
Apr 20, 2011
Heya so im close to be done with this project but unfortunately i still have a couple of questions ill start with the first, imagine this listbox contents:
[Code]...
Now imagine theres a string with : "2-12-2009 | 11:30"How can i delete a listbox item if the string matches the listbox item text after the arrow?It might sound a bit confusing but what im planning to do is to delete a listbox item based on the date of the event and not the date of the alarm.
I have a SQL 2005 table called Customers and i would like to query the table for exact match and partial match. The exact match query is working OK but when i use the partial match, it doesnt return any result. Strange thing is, it works inside the query designer, it returns rows. On the dataset, if i right click and say 'Preview Data' and supply the search criteria, it doesnt bring in any rows. Same happens in the vb.net form also. Instead of partial string, if i supply the full customerid, it returns a row.Whereas I can return rows on another table, Suppliers. I dont know where the problem lies. Here is the sql:[code]In fact, I am trying to use the wizard generated code and details on the form. No changes done to the code or form.The customer id is nchar(10) column and is the primary key also. I ran the same steps on the Northwind database too, and the same problem exists.
What i am trying to achieve is that there are 7 columns in my db table. one is primary key and rest 6 are integer columns. Now my application will allow user to input 6 values. I want to compare 6 values entered by user to those 6 integer columns and if in any row 3 or more columns match user's input Primary key of that table is returned..I have tried using queries, cursor, nested loops and i am still unable to achieve my results..
UPDATED :DB Table Structure.. I am inputting 2,3,7,11,45,65. Number of returned rows should be 5. eg..
Using vb.net 2003 asp.net 1.1. I have this C# function that I converted and I gettinga squiggley saying full and partial not part of string, this is converted from a .cs file.
Here is the function, maybe I'm not seeing something: Code: Public Function RefundTransactionCode(ByVal refundType As String, ByVal transactionId As String, ByVal amount As String, ByVal note As String) As String Dim caller As CallerServices = New CallerServices [Code] .....
i'm making an twitter app. but i'm having a problem..In my listbox there is a list of username's i have to sent a tweet.this is the code i'm using:
For i As Integer = 0 To ListBox1.Items.Count - 1 ListBox1.SelectedIndex = i Dim value1 As String = ListBox1.SelectedItem.ToString Dim value2 As String = value1.Replace("http://twitter.com/", "")
[code]....
but it doesn't work..it goes super fast and only fills in the last listboxitem.i want now that every 10 secs a new listbox item is filled in in the status box on twitter and posts the tweet.
I need to render a partialview to a string, and I am trying to convert a C# example to VB.Net, as I am stuck with that for this project.This is causing me a headache from these two problems:
ObjectViewData - I can't figure out what that is RenderPartial is a sub, but seems to be used as a function - I don' get it
I reference the MVCContrib.UI, so I don't need to convert that. But these two functions, I do need to convert:
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 have extended an Entity Framework 4 entity class with a calculated property in a partial class. This member is not available on the client to which the entities are exposed via WCF RIA Services.when using C# appears to be changing the extension of the partial class file from .cs to .shared.cs. I tried this with my VB.Net solution (.vb to .shared.vb) and got a long list of errors. I believe what happened is that the partial class lost its association with the entity on the client - it inherited from object rather than EntityObject.
My best guess is that this is related to the way that VB.Net handles namespaces.Each project has a 'Root Namespace' which is prepended to anything that is defined within a code file. C# has a 'Default Namespace'which is the namespace into which new types are placed by default - via a namespace statement within the file.The partial class is probably having the client namespace prepended to it which puts it into a different namespace than the entity with which it is associated on the server.Is there any means of extending an entity in such a way that those extensions are available on the client via WCF RIA Services and VB.Net?
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 find myself copying single files to multiple different machines, so would like to create something to help.I would like a numericupdown, which dynamically adds text boxes (which will be destination file paths). I will obviously need it to remove them too when I decrease the number.
I am making a question and answer game, and I would like to be able to give the user some slack in the answers if they were to misspell a word by a letter or two, like if the answers was Jumps and they type Jump if you did a comparison of them like If string1 = sring2 then do whatever, but obliviously those to string dont match, so it would return false, even though it is the right answer, I came up with this routine to compare two words and if the percentage of the letters are higher then 82 % right it will give you credit for your answer.
i have a string named Workers that had multiple lines of text. I need to search those lines for the term "BackGroundWorker1" if it is found then do something if not do something.
I need a way to compare multiple strings to a test string and return the string that closely resembles it:
TEST STRING: THE BROWN FOX JUMPED OVER THE RED COW CHOICE A : THE RED COW JUMPED OVER THE GREEN CHICKEN CHOICE B : THE RED COW JUMPED OVER THE RED COW CHOICE C : THE RED FOX JUMPED OVER THE BROWN COW
(If I did this correctly) The closest string to the "TEST STRING" should be "CHOICE C". What is the easiest way to do this?
I plan on implementing this into multiple languages including VB.net, Lua, and JavaScript. At this point, pseudo code is acceptable.
I am not a regex guy, so I need a little help, just cant get my head around this...
I am writing registration page and using asp.net validators. I need a regex validator to match a special character anywhere within a word, so it will satisfy requirement which says that "ID must have at least one special character." Allowed characters are[code]...
Once again, I am a junior, and having problems with wrapping my head around this stuff at this moment..
I want a regular expression for the following issue:I want to match a string that contains A,B,C,D,E and F. string length should be 0 to 6. and not character should be repeat in the string.Example: ABCDEF, ACDEFB, EFBCDA, etc. but not ABBCDES/W Engineer
I have a simple string : s:10:"char1";s:2:"13";i:1;a:8:, i'd like to match that 13 from inside " ", in PHP i would do something like : /s:dd?:"char1";s:dd?:"(.*?)";i:dd?;a:dd?:/i but i'm not good in vb's match methods,so please give me full example how i can match what i need ( it is possible to be multiple matches (2) ).
I'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.
Well my question is simple, I want to match a string with following attributesNo white spaceMust start with a letterMust not contain any other special characters other than nderscore
