If String Contains String Pattern Return Value
May 4, 2010
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]

I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

I have the following web method:
<WebMethod()> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json, UseHttpGet:=True, XmlSerializeString:=True)> _
[Code].....
I wanted to use HttpGet here so that the result can be cached.
I tried every variation of calling this, but no luck. Is this possible with GET?

I 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?

Im 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?

I need a regular expression that I can use in VBScript and .NET that will return only the numbers that are found in a string.
For Example any of the following "strings" should return only 1231231234
123 123 1234
(123) 123-1234
123-123-1234

I have a class in this class i call a function which should return some string the class connects to an ftp server and list the directory and returns the filenames of the dir.
Code:
Public Function GetFileList(ByVal host As String, ByVal username As String, ByVal password As String, ByVal currentdirectory As String) As List(Of String)
Dim oFTP As FtpWebRequest = CType(FtpWebRequest.Create(host & currentdirectory),
[CODE]..........
So this should return all filenames of that directory
like:
Data1.xml
Data2.xml
Data3.xml
Now i have a form with a listview where i want to call this function and get the files of the "olist"
Code:
Return oList

I have an third part dll that have a function that returns a string.When I call the function I got for example "123456" back. At least it seams like that, but when i do mystring.length it does not return any length. If I set the text property of a label it shows "123456".
When I have the string I got from the dll I send it to a webservice function:
rem call dll and get string
dim mystring as string=mydll.getstring()
rem Send it to the webservice
webservice.SaveString(mystring)
The webservice crashes with an webexeption ("protocoll error") when I send in the string I got from the dll. If I instead send it like this:
rem call dll and get string
dim mystring as string=mydll.getstring()
rem Send it to the webservice
dim FixedString as string = mid(mystring,1,6)
webservice.SaveString(mystring)
Then it works and everything is fine. That leads me to think that the string I got from the DLL is in someway not terminated correct.And I dont know how to fix it from vb.net (I cant change the DLL)and I dont know in beforehand how long the string will be.The dll does only work on site when specific hardware is connected so I can't sit at the office trying to fix this in dev-environment. So I would like to have some possibly solutions to this before I go to the customer again.
Edit 1:I tried to just do a loop that looped from 1 to 100 (because I dont know the real length) and tried to copy all characters that <>"" to a new variable but it didnt work. I didnt try other variants because the day was over and I had to leave the customer site.
Edit 2:The DLL Im talking to is made in VB6. That DLL is talking to other DLLs that is made in C++ (I think).
My program < - > vb6-DLL <-> c++-DLL <-> hardware

I have a string (bufferedstring) which contains:
blah blah blah Version V3.5/7(030114) blah blah blah blah
I'd like to parse out the Version V3.5/7(030114) part using a Regex or Substring, but not sure how. The surrounding text could be dynamic in length and the 6 numbers between the parenthesis could be a different length as well (maybe 4).
how would I get just that string out?

I'm sure but can't see the answer. Currently going through a string "DO While Not ts_IN.AtEndOfStream" looking for information. This includes then checking another string (while inside the first) for matching reference point for further data.
So within the first loop, I have a second loop "Do While Not ts_IN2.AtEndOfStream". And looping through that string searching for the reference point.
This works initially, but after awhile don't find anything because it is not going back to the start of ts_IN2 string each time loops on the first section.

Public Function Foo() as String() Dim bar As String = {"bar1","bar2","bar3"}
Return bar End Function
My situation is similar to the code sample above where I'm returning a string array from a function.
What I would like to do is just return the string array without having to declare a variable first and then return the variable.Something like this, although this obviously doesn't work:
Return {"bar1","bar2","bar3"}
Is it possible to do this, I can't seem to find a method that works?
