Matching A Specific File Name Structure With Regex?
Jun 21, 2011Regex in VB2008.I have a file system directory that my code is watching. When a file is placed in that directory my code kicks off a processing application. Based on the filename structure, the code will perform different processes. So I need to match the filename structure specficially to get the correct processes to run on that file.My file name structure is: IK2YYYYMMDD_VV.e;where YYYYMMDD is well, the year, month and day. And VV is a verison number from 00-99 If the new file saved in the directory match this structure then I want a TRUE returned. From a filewatcher I get the filename as an "e.Name" (FileSystemEventArgs) variable. My current code to see if it matches the baseline structure is;
Dim IKPred2Match as New Regex ("^IK2.*\.e$") Dim ValidIKPred2Match as MatchCollection = IKPred2Match.Matches(e.Name)I've tried many different regex match patterns, and just can't seem to find the magic one.
VS 2010 Simple Regex Pattern Matching?
Jul 1, 2011I 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?)
Correctly Matching Ending Tag With Its Starting Tag In HTML With A RegEx
May 29, 2009I'm using VB.Net in an ASP.Net 2.0 app to run some regular expressions that remove some unnecessary markup. One of the things that I'd like to do is remove span elements that don't have any attributes in them:[code]I'd like to remove the outer span elements. Unfortunately, my regex above gives me this as a result, since the closing span matches the first one it comes across:[code]
View 4 RepliesRegex - .NET Regular Expressions, Matching Escape Characters?
Dec 3, 2010I want to use Regex.Replace to replace a Match with a context sensitive value. I use the MatchEvaluator for this. But to make things simpler lets say I'm matching %v I want %v to be escapable, so if I use \%v it will not match. Anything else should match.
The pattern I came up with is this: (?:[^\]|^)%v It basically matches %v if it occurs at the beginning of the string, or if it follows any character except . It doesn't capture the first part of the expression.I know this isn't the "right" way to do it. But it worked just fine until I noticed that when I use this pattern in a replace, it includes the character before %v in the replacement(duh, right?)So, if I have ThisIsAValue:%v and I do Regex.Replace, replacing with the string Value, my result will be ThisIsAValueValue instead of ThisIsAValue:ValueI've tried googling this but the fact that "escape character" is so heavy in RegEx, all the results are geared towards the USAGE of escape characters instead of picking them out with a pattern.
VS 2008 Multiline Regex Matching Doesn't Work

Regex - Matching And Replacing The Contents Of Multiple Overlapping Sets Of Brackets In A String?
Jun 5, 2011I am using vb.net to parse my own basic scripting language, sample below. I am a bit stuck trying to deal with the 2 separate types of nested brackets.
Assuming name = Sam
Assuming timeFormat = hh:mm:ss
Assuming time() is a function that takes a format string but
has a default value and returns a string.
[code]....
I could in theory change the syntax of the script completely but I would rather not. It is designed like this to enable strings without quotes because it will be included in an XML file and quotes in that context were getting messy and very prone to errors and readability issues. If this fails I could redesign using something other than quotes to mark out strings but I would rather use this method.
Preferably, unless there is some other way I am not aware of, I would like to do this using regex. I am aware that the standard regex is not really capable of this but I believe this is possible using MatchEvaluators in vb.net and some form of recursion based replacing. However I have not been able to get my head around it for the last day or so, possibly because it is hugely difficult, possibly because I am ill, or possibly because I am plain thick. I do have the following regex for parts of it.
Detecting the parentheses: (w*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))
C# - Shall This Regex Do What Expect From It That Is Matching Against "A1:B10,C3,D4:E1000"
Mar 9, 2011I'm currently writing a library where I wish to allow the user to be able to specify spreadsheet cell(s) under four possible alternatives:
A single cell: "A1";
Multiple contiguous cells: "A1:B10"
Multiple separate cells: "A1,B6,I60,AA2"
A mix of 2 and 3: "B2:B12,C13:C18,D4,E11000"
Then, to validate whether the input respects these formats, I intended to use a regular expression to match against. I have consulted this article on Wikipedia:
Regular Expression (Wikipedia)
And I also found this related SO question:regex matching alpha character followed by 4 alphanumerics.Based on the information provided within the above-linked articles, I would try with this Regex:
Default Readonly Property Cells(ByVal cellsAddresses As String) As ReadOnlyDictionary(Of String, ICell)
Get
Dim validAddresses As Regex = New Regex("A-Za-z0-9:,A-Za-z0-9")
[code]....
1. Is my regular expression correct? If not, please help me understand what expression I could use.
2. What exception is more likely to be the more meaningful between a FormatException and an InvalidExpressionException? I hesitate here, since it is related to the format under which the property expect the cells to be input, aside, I'm using an (regular) expression to match against.
Datagridview - Remove Wrong Columns And Display The Wrong Data
Jan 12, 2010I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

Concatenating A Variable With A Regex Group Match In Regex.replace?
Apr 5, 2012I am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?

Regex Builder That Actually BUILDS RegEx From A Highlight

Open -209.037
18N694 P321 117461, 50374 100MIL;
from the line i must take P321 and match with my File2 if i find the mathing line like this
12N709 11.3611 4.9474 P321 L6 BOTTOM 100MIL 43-CHISEL X11.3611Y4.9474 1922 0
then i must take the value beside P321 which is L6 and write it in my original file like this
[2 11.63 39.7] X7.705 Y0.735 209.037
Open -209.037

Combo Box Matching Text?
Nov 29, 2011In VB6 datacombobox there was a property that you could set that filtered the item list as you typed in the combo box (extended matching I think it was called) so that as the user typed more characters in the box the filtering progressively narrowed down the number of items in the list.The .net control does not seem to have this facility, or does it?Do we have to programatically do it now?
