Is there a way to search for a string pattern in a string ?
i have 1000 of strings and example of one is - 'won 2 races in town, 1998, and then moved to'i wish to search for the ", ####," as all the strings are in the same format (note that the year is different every time hence why not using the instr)
I want to search for a String Pattern in a Binary File (Binary File is not 100% plain text). Here is the pattern:
"**_*_*_*"
or
"111_11_11_112"
It is for vb.net 2008 with access database.At the moment it matches based on paramValue, and needs an exact match.How can I change it to look for a pattern instead?? For example I want anything that contains the text "Fizz" and then "Bom".[code]...

As a continuation of my other thread, "Finding A Pattern without a string Array (http:[url]....)", I would like to continue asking questions about enhancing a scanner with a few things:
1. Here is my code for finding signatures in a file:
'First the Signature Class:
Interface Signature
End Interface[code]......
How would I remove an alpha-numeric sub string in a string that meets these rules:

L###LL
l = Leter
# = Number
I am struggling to extract a 'matched' string and wonder if I am missing something simple.Let's say my code finds a string 'abcdefgh -john. smith 1234567 a123-a-123-f the last search, abc, 123 ;'I am searching this string for the pattern '[a-z]###-[a-z]-###-*'I know this text appears in the string as 'a123-a-123-f'I would like to be able to return the matched string value 'a123-a-123-f' to a variable.If I place a wildcard * in front of the pattern, it will find the text, but obviously everything else in front of it, is there a way that somebody can think of to strip the variable without using the preceding wildcard?I am not worried about the wildcard on the end of the string as I can strip back to the last space.[code]
View 3 RepliesI have a networkstream (using C#/VB.NET). while on reading values coming like this:
&% 68 kg K A&% 23 kg K A&% 174 kg K A &% 68 kg
&% 34 kg K A&% 2334 kg K A&% 68 kg K A &% 68 kg K A
&% 2348 kg K A&% 78 kg K A&% 28 kg K A&% 68 kg
The numerical(weight) value will be continuously varying.
Every time i am reading the starting of the stream differs. But the pattern remains the same. How to split that into '&% 78 kg K A' which represents one set.
How to extract the weight value from this stream using Regex or any other methods?
Could someone please guide me on the correct format string to display a time in the following format? [code] Is there one format string I can use to accomplish this?
View 3 RepliesIm trying to make an on access file scanner, YES I know that C++ is better, but this is a concept of thought, trying to challenge myself to see if its possible in vb.
Anyways, I have a list of Hex definitions, my question is, how can I index this list so I can access the definitions faster. A definition looks like this:
Eicar.Test.File.a=58354f2150254041505b345c505a583534285
The part after the equals sign is the HEX signature, while the first part is the name of the definition.
Basically what I am trying to do is index them somehow where I can scan faster, as I have over 60,000 definitions and I have to split each individual one in order to get the signature name. It takes about 45 seconds or so to scan a 500KB file. I need it to be WAY faster.
I'm trying to find a pattern in a string, I guess is very easy but I'm terrible in regular expressions. I have a big text and I need to find all the next type of pattern:
{a|b|c}
That can be also something like this: {a|b|c|s|f|f|ft|r} or any number of items inside but at least 2 items so the pipe symbol is another key. Is this an easy regular expression? I'm using vb.net 2005.
I am trying to parse a string that contains known and unknown characters.here is an example:
[1]Tue Jun 19 17:14:15 2012, 48:17:4C:00:00:74, 4.8, 5449,816324, 26, 31397, 160855, 30775030, 29962782, 812248, 2394476, 71619, -44, -67, 46, -60, 51, 0, 86468, 2547055, 4687358, 44278, 4593, 65076, 65191, 65106, 65166, 65108, 64552, 64572, 64512, 5.1, 2548502, 4690906, 520, 0, 0, 0, 36, 2412
[code].....
The known part is the [0] or [1] or whatever number in the brankets.the unknown part is the rest of the message.So if i have this string i want to cut it to smaller substrings that start with [ and end before the next [ .To make it more tough, sometimes, before the next [ there is another message that comes like: Jun 19 17:13:40 2012 timestamp And after that it continues with the next [
I need to be able to serialize a class into a string, and I know of 2 patterns:
1) (normal) Serialization pattern
2) Proxy Serialization pattern
I've read [URL] (the only website in google that talks about the proxy-serialization pattern) and still cant find the advantage or benefit of using this pattern. Could someone explain what exactly is the proxy serialization pattern, or rather exactly what problem does the proxy-serialization pattern solves that the normal-serialization pattern doesn't solve?

View 3 RepliesI have written a program that uses an array of the english alphabet and Morse code. I also built a form with a input box for the alphabetic information and an output box with the Morse Code. What i am trying to do is basically type a word like "Hi" in the input box and produce the Morse Code equivalent in the Morse Code output box. [Code] This works but only one letter at a time. Do i need to Parse the string of characters one at a time, and then run it through a loop like i have created?
View 6 RepliesI have a non standard text file, ie its not delimted etc, its pretty much free flowing. What I want to do is to search for a specifc string eg. "xyz123" and then replace it with what a user types into a text box, lets call the text box and its contents "txtreplace".
I am trying to replicate a find and replace function essentially, but will need to tailor it later on down the line, but this will be a starting point.
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.

View 2 RepliesI am trying to perform an action if the index of a string contains a certain value, but it's just not working quite right and I could use a hint if anyone has done this before.The application pulls in a .txt file and manipulates it to create 3 other different type of files. It is currently set to pull the information from line 3, but the output program that supplies the file will probably change to line 2 or 3. I need to either search the whole string or the index of line 2 and 3 and then do the following manipulations. It will not return the value of line 2. This is what I have tried, but is not working. The code commented out at the bottom is what is currently there.
The .txt file shows the following values so far:
1 PAGE 1
PIPELINE REF RA10-FX-604-01-

Need to take a string in vb and split it. Also need to look through the two returned values and return the value which contains [URL]. Pipelines are the delimiter.

Recently I have started my computing course at college. I had little programming knowledge (as I'm more of a 'web developer') and it has come to the point of us learning some of the basics.I downloaded VB at home, and have been learning by myself when I have the chance... but I've hit a wall Basically, I have to create a program that searches for a character within a string.I managed to do this at college, but it has slipped my mind... So I could use some help The specification we have to meet is:An event (such as a button being clicked) must use a function to return something.The function must use the mid() function
From this, I've come up with:
Public Class Form1
Dim string1, searchterm As String
[code].....
The layout of my program is effectively 2 text boxes (named input1 & searchterm), a Label (named Output1) and a button (named search).ow, My problem (I think) is due to the mid().I'm not entirely sure I've used it correctly.

View 2 RepliesI 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"
