Extracting And Replacing Paths?
Aug 19, 2010I have file paths such as:
' Any number of folders before and after the Project name
C:acdProject1efgsomefile.someextension'
How would I:Extract only the path before the project name?
C:acd
Extract the path after the project name?
efgsomefile.someextension
Note: Of course given the filename.Would Split be better or some complicated regex?

.net - Replacing The Regex Date?
Nov 16, 2011I have dates like the following (note trailing 'T')
2011-11-07T15:24:28
2011-11-07T
With regex i need to extract just the date part so both will look like this
20111107
20111107
.net Have a webservice that is returning a date like 2011-11-07T15:24:28, but on some occasions it returns date with no time but still with the trailing T. This causes .net's cdate function to bail out.
Replacing For Each Stringbuilder With A Regex?
Jul 29, 2009I have a sub that takes a string, replaces all characters that are not alphanumberic and or a "/" and replaces it with a space. Then it goes through and replaces all multiple spaces with a single space.
Right now I am using a string builder to do this. My problem is that this action must be done several hundred to thousand times depending on the filesize I am comparing it to (1 richtextbox line = 1 string)
I believe I should see a significant increase in performance if I can figure out how to do this using a single regex.replace function.How would I go about constructing a regex.replace function that would keep all alphanumberic characters and "/" and replace everything else with a single space?

View 4 RepliesRegEx, Finding And Replacing A Certain Substring?
Jan 27, 2009I've got a string which could or could not contain the substring "/announce". I would like to replace this part of the string with "/scrape" if its found...so far nothing tricky. But heres the thing: I only want to replace it if the '/' in it is the last occurring in the string. Heres what I mean:
Heres a scenario where I want the replace to happen:
MyStringWithRandomText/announce?x=19
would become:
MyStringWithRandomText/scrape?x=19
And heres another scenario where the '/' in announce is not the last '/' occuring in the string, so I dont want to replace it:
MyStringWithRandomText/announce/foo?x=19
I hope that made sense. Not sure if there is a way to handle this by only using RegEx

RegEx Query - Replacing Spaces Within Parts Of A String?
Oct 24, 2011I have a program that goes through SQL statements, identifying component parts with a space. eg: -
SELECT * FROM tblSales WHERE CustomerID=10 AND Year=2011
Would produce the following as separate components: -
"SELECT","*","FROM","tblSales","WHERE","CustomerID=10","AND" and "Year=2011"
The problem I have however is the use of spaces within values eg.:-
SELECT * FROM tblSales WHERE CustomerNameID='Test Company' AND Year=2011
Using the same space-separating logic, this would produce components of:

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*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))
.net - Regex Replacing Non-words Chars In Strings, Ignoring Specific Chars?
Oct 8, 2011In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

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
Nov 17, 2011I've been working straight since yesterday trying to get this to work.

Jan 14, 2010My development machine runs Windows XP, but the target machine runs Windows 2000 with .NET 2.0.I've set my compile options to compile 2.0, which is fine.However, I have some references which are causing issues.For example, Microsoft.Office.Interop.Outlook.dll - in VS2008 the path is shows as the C:Windowsassembly folder which works fine. Until the app is built and run on the target machine and fails:Could not load file or assembly 'Microsoft.Office.Interop.Outlook, Version=12.0.0.0, Culture-neutrl, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.Presumably because on Windows 2000 the assembly folder is C:WINNT.I cannot work out how to target the WINNT folder for my references.
View 9 RepliesAdd File Paths To A CheckedListBox?
Feb 4, 2011The end result I am looking for is I want to add File Paths to a CheckedListBox. I only want certain file extensions and if a file by the same name but a specific extension exsists allready then I do not want to add those files to the CheckedListBox.
Example: I am only wanting these filetypes in my CheckedListBox (.gif, .tif, .bmp, and .jpg).However if the filetype (.PNG) allready exsists with the same filename (i.e. image. png and image.jpg) I then do NOT want to add that JPG. Only files that do not allready have a PNG with the same name. (I hope I was able to make this clear)
