Parsing File For This Pattern "Feb 06 2010 15:49:00.017 MCO"?
Mar 2, 2010
parse a file for lines of data that start with this pattern "Feb 06 2010 15:49:00.017 MCO", where MCO could be any 3 letter ID, and return the entire record for the line. I think I could get the first part, but the returning the rest of the line is where I get lost.Here is some sample data.
Feb 06 2010 15:49:00.017 MCO -I -I -I -I 0.34 527 0.26 0.24 184 Tentative 0.00 0 Radar Only -RDR- - - - - No 282356N 0811758W [code].....

I'm wanting to have the option in my app to save configuration settings and then be able to import them on another machine or when the application is launched later. So I've got my saving routine working fine, using the XmlWriter class to write various settings to the XML file. I'm not quite sure what I should be using to do the parsing of the XML file to read the settings back in though, as there seems to be a few different ways to do this.Should I be creating an XmlDocument instance from the XML file and then using the ReadNode method or one of the other similar methods? Or should I be using the XmlReader class and one of its methods?is the format of my XML file:
<?xml version="1.0" encoding="utf-8" ?>
<!-- MY_APP_NAME Saved Settings - Version 0.9.5.0 -->
<SearchSettings>

Just a little problem; seemingly easy but doesn't seem quite so straightforward as it should be. I am pulling an XML file from a server using the web browser control and the using the DOM innertext property to assign the contents of that XML page to a variable.
I would like to be able to efficiently parse through this variable as if it were an XML file. I have posted the output below.I can work out how to load an XML file using the LoadXML method from a disc or URL but I would prefer to parse it from within the variable. I know this should be simple but I was wondering what the best class to use would be as the most efficient / easy way of parsing data.
I am basically looking to extract each of the details for each <application> into an array.

I am reading in a line in this format: AL93895200 How do I get each of the items in the line that are separated by a space. I think it should go something like this:
Dim line As String = fileReader.ReadLine() Dim fields() As String = line.Split(How do I get it to split at the spaces?)
But as you can see, I don't know how to actually get that to work.

I am refining my VS2010 control renderers and I'm working on the TabControl at the moment. If you take a screenshot of the VS2010 IDE and zoom in on the background of the TabControl (where there are no tabs), then you might see that it consists of a pattern of dots with a slightly different color than the surrounding background. I am trying to draw these dots (yes, I'm going for perfection), but I cannot find a brush that allows me to do this.I am pretty sure I'd have to use a HatchBrush with the right HatchStyle, but I cannot find a matching style.Here is a screenshot showing:
1. The VS2010 background I'm trying to draw (higher contrast and brightness otherwise it's hardly visible),
2. The HatchStyle that is closest to this (DottedDiamond)
3. Why this HatchStyle is not correct (it's missing dots where the green dots are, which I photoshopped in).
Now of course I'm going to have to draw the pattern twice (there are two patterns, offset by 1 pixel, with a slightly different color), but the more pressing problem is the green dots seen in the third image. They aren't there with the DottedDiamond style, and no other style (I think I've tried them all, but hey I might have missed some..) produces a better output.

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 [

Has anyone ever used VB to analyze data to find patterns? I would like to analyze several hundred sequential data points to look for a fairly uniform "up-down" pattern, very similar to a square wave.

I need an extremely simple regex pattern that matches anything within square brackets [].
Example:
This is a [test] text with [some] [examples].Required results: [test], [some], [examples].I don't want to get rid of the brackets, they should be included in the result (that should make it easier, right?)
If possible I'd like to exlude results that have whitespace in them, so things like [this string] should not be matched. If that gets too hard (probably not, but hey I can't even manage this :S) then I don't really mind, I can always check if the result contains whitespace myself.
I tried a lot of examples I could find online and ones that I could think of myself but none work. Note: I've been testing with the Visual Studio Find dialog (checking to use regular expressions obviously), maybe that's where the problem lies, because I don't really understand why some of these don't work...
Anyway, first thing I tried was simple: match the two brackets and one or more characters in between (that should be a +, right?)

It seems up until now I've never used Regex, nor even heard of it. But once I did I realized how extremely useful this is. Having said, it's been 2 days since I've began looking into constructing my own patterns. My most recent being for decimals. Is the pattern I provided below "proper"? and are there also any improvements I could be making for a more efficient patter, which would minimize any possibility of a loophole? [code] So for my use, this is doing what it's supposed to being doing under every test I can through at it. But do mind the 0. and .0, I have a function to normalize these as they are proper, I just pad the left and right accordingly. I found most regex questions asked here..and yes I am doing this in vb.net so it fits. If not, then feel free to move this post somewhere else better suited for the topic of discussion.

I need to parse a string that consists of fields in quotes, separated by commas. Using Split would work fine, but sometimes one of the fields has a comma in it. ie. "My Company, Inc","USA","12.50","125000"I'm just looking to get the fields into elements in an array. Can someone suggest a way to handle the embedded commas that are sometimes present?

I am using the xmldocument (loadxml) and xmlPathNavigator to parse xml files I am compiling through a incoming stream. The first point of processing the files is to split the file into the different entries and add those to a list. I do this using either xmlPathNavigator or string.split if either one fails.At times both will fail because of some issue in the xml and would still like to salvage the file contents without having to fix the xml. I tried to use regex parsing but its not producing the content as I would like. I use the following code but in the end I do not get all the contents of the entry, only those between some of the tags.

I am writing a tool that logs stats for a first person shooter game. The game writes its information (including who killed who with which weapon) to a log file, which I read every so many seconds and parse so that I can write that information to a database.I am now having trouble parsing the weapon out of that string of information.
Some additional information is required: a weapon in this game can contain attachments (such as a scope, a grenade launcher, etc). Weapons can have either 1 or 2 attachments. Some weapons however cannot have any attachments at all.
Each log file entry that describes a kill contains a code that describes the weapon that was used. This code is a concatenation of either 3 or 4 parts:
<weapon>_<attachment>_mp
<weapon>_<attachment1>_<attachment2>_mp
where <weapon> is a code that describes a weapon and <attachment> is another code describing the attachment.This should be easy to parse by just splitting along the underscore characters, but there's a few catches:
1. Some attachments are able to kill players as well. Specifically: grenade launchers, flame throwers and underbarrel shotguns. In this case, the attachment is listed before the weapon:
<attachment>_<weapon>_mp Note also that in this case there is always only 1 attachment.
2. The biggest catch: some weapon names have an underscore in them (some even have 3 underscores)! So simply splitting along the underscore won't work in all cases; if the weapon name contains an underscore I'm splitting the name of the weapon..This makes the list of possible combinations a lot longer. The ones I can think of (I think these are all):

It has multiple tags like this:

<td style="text-align: center;">001</td> <td style="text-align: center;"><a href="http://www.pkmdb.com/DL/PKM/bulbasaur.pkm">Bulbasaur</a></td> <td style="text-align: center;"><img src="http://www.pkmdb.com/res/types/grass.png" alt="Type" /></td>Different Number, different name. I need a way to get the number and name out of these tags. I'm rather terrible at this, and I've seen examples on the site, I just don't know where to start really on this.

I have written a function which logs into an FTP server and recursively lists all of the directories within a given folder into an XML string (example below). I basically want to parse this into a listview item in the format as follows "Level1/level2/level3/level4" (standard file path). I have given an example of the xml below. How would I go about achieving this?
I have set up an xmltextreader, and then using a do while xmltextreader.read() I can check the current level of the node and add it that way, but it tends to only work half the time - is this the best approach?

I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

I am trying to create a program in VB.net to help me fix broken computer systems by parsing log files. I have some ideas but I have only built simple programs previously. I have ideas how to do this but so far my attempts haven't gone so well.Specifically I can either import a txt type file or copy and paste the contents of a txt file into the program and then have it compare what has been posted to a good/bad list then it reprints out what is bad in color coding. Also if their is a way to update the file it uses for comparison by entering in a txt file that would be stellar.

Let me preface this by saying I'm VERY limited in my programming knowledge/experience using any language. I mean I have extremely basic capabilities and don't quite understand this stuff inside and out like most of you do.Anyway, I'm trying to code a fantasy football draft program in VB 2010 that utilizes the MS Internet Transfer Control 6.0. It will retrieve the HTML from a website, say ESPN, and parse the data into player names, rankings, and other stats. Should all be simple strings/sub-strings. It will then populate a DataGridView control so that each row in the DGV has the player's name, ranking, projections for the season, etc. After this has been populated, the program will be designed to allow me to draft players and assign them to the various teams automatically. I am the commissioner and we do an off-line draft, so I will just make picks for everyone and submit them online later.
