VS 2010 Repeated Pattern In String?
Jun 19, 2012
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 have a List in Do-Loop. That List is collecting some information with programmatically. So, How can I know and end the loop if List repeated in loop.
Code like this:
Dim X As New List(Of String)
Do
------
Loop While X IsNot Nothing
My code can't quit from loop and it repeats the list from first string. I want to know how can I determine the last value of list to change script like this:
Loop While X.Count = 10

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 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 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 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.

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.

a debate has been sparked here about the use of the strategy pattern in my classes.
Basically, I have a 'Shape' object that is an interface 'IShape'. We have 'Circle', 'Rectangle' and 'Elongated' that are the concrete classes that must implement the IShape interface.

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've run into a bit of a roadblock trying to figure out how to programmatically not allow the same data in multiple comboboxes. I'm usnig VS2008 and I have 3 comboboxes on a form, all with the same data, say "apple", "orange", and "red". The comboboxes are nothing more than a user definable sorting method on which gets calculated first. When I use the .SelectedItemChanged event on any of these, I'll obviously be duplicating. Any idea on how I can program to automatically switch the combobox that is duplicated to the value that is missing? I don't want to hard code it as further down the road I will have up to 7 comboboxes. Below is what I started with coding. Not sure if it is the best way to go about it, but it works on 4 of the 6 combinations.

Is there a way in LINQ to Entities (SQL) to identify all records where a specified word is repeated at least/less than a specified number of times?
I can do this in memory, looking for at least 3 instances of the word "word" using:
Where(Function(x) x.Description.Split("word").Count > 3)
However the Split() function cannot translate to a SQL equivalent, and so this can only be executed in-memory, which is excruciatingly slow by the time any number of records are involved.
The SQL to do this would be something like
WHERE Description LIKE '%word%word%word%'
And that's as far as I get - I can't work out how to get that SQL generated by LINQ to Entities. I tried the ugly hacky .Where(Function(x) x.Description.Contains("word%word%word") on the off chance, but I'm almost relieved that it doesn't work!

I'm trying to create a form with a lot of repeated components. I'm making a touch screen control system with a GUI in VB.net. I would like to make it so when a textbox is pressed a form pops up (form1.show()?). This form is basically a number pad. The user can press buttons (0-9) to get the desired integer to appear in a text box in the popup form. When the user presses an "Enter" button, the popup form returns the integer value that was entered to the initial textbox pressed.

So although we have plenty of keys from our subscription, to minimize tracking and confusion we just want to use2 or them over and over as we install, test, extended test, wipe and reload. Eventually we would have to recycle any way. Much of this will be scripted /automated and we were wondering what kind of problems we will run into for the activation cycle (human intervention required, phone call, etc.) Mostly working on Win7 (all versions) but still need to do some Vista and even XP.

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.
