Basically I want to retrieve all possible substring matches with n characters from a string, Here's my initial code but it only returns 2 matches.[code]...
View 3 RepliesNot sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

View 1 RepliesI'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:
Widgets.xml
I would like to execute a single RegEx Replacement that would result in the string being:
ACE_Widgets.xml.
Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:
^ACE_{1}[dD]+
Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml
The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.
The following posting is close to what Im looking for, but with the inclusion of the *ix directory path prefix, and the use of preg_replace() in PHP, I'm having a bit of a struggle getting it to work with what I need to do:

I'm writing some code that takes a report from the mainframe and converts it to a spreadsheet. They can't edit the code on the MF to give me a delimited file, so I'm stuck dealing with it as fixed width. It's working okay now, but I need to get it more stable before I release it for testing. My problem is that in any given line of data, say it could have three columns of numbers, each five chars wide at positions 10, 16, and 22. If on this one particular row, there's no data for the last two cols, it won't be padded with spaces; rather, the length of the string will be only 14. So, I can't just blindly have

View 3 RepliesI'm trying to integrate a parental controls feature on my webbrowser. Now, the user creates a text file containing a list of the words they don't want their child searching. Here's an example of what would happen. The list looks like this (I wont use vulgar words):
dog
cat
baby
fish
tree
and the kid tries going to "treeandbabynectar.com". I want a messagebox to come up saying "Site blocked". I want it to be able to detect the tree and baby in treeandbabynectar and realize the text file contains the word tree and baby and block the site. Is this possible? How would I do this?
I need to create a console program that allows you to enter a string, of which is then outputted in reverse.

Apparently I need to find out about strings and will also need to use a loop.
I've been working on this RegEx for the past day or so and I think I have it worked out so that it returns the data I want. First a little background.I have a content editor that users will be able to edit web pages. They can format text, add links, etc.. standard content editor stuff. When they click save, the editor provides the ability to get the content (editor.Content) and put it into a string. What I want to do is get any links (<a> tags) and find out if they are internal or external links and if they are PDF files.
Here is the Expression I've come up with:
<a[^<>]*hrefs*=s*[""'](?<domain>https?://[^/s'""]*)*/?(?<path>/?[^s""]+?)?[[>""']
With this, I am able to separate the domain (if it has one) and the path out. Then, I loop through the matches...
dim matchColl as MatchCollection = Regex.Matches(editorContent, regExString)
For Each m as Match in matchColl
If m.Groups("domain").value <> myInternalDomain and m.Groups("domain").value <> "" then
'this is an external domain... do some stuff
[code]....
My question is this... the parts where I 'do some stuff' to the values, what would be the best way to get that back into my 'editorContent' string? I could probably put the editorContent into a StringBuilder and do a whole bunch of replaces on it, but is that very efficient?So, for example, with the PDF, I want to specify that it open in a new window (target="_blank") and for the external URL, add some javascript code into the onclick attribute.
i have to search a string for a few words eg, dog, cat, lion but i want regex to fail if lizard is found in the string even if it contains cat, dog or lion.ismatch(pass) "dog|cat|lion" "This is not your average cat!"ismatch (fail) ??? "This is not your average cat! It's a lizard."??? - here the regex statement is unknown word spaces and boundaries or lower/uppercase is not a concern. I run the string through Replace(" ", "").Trim(" ").ToLower before handover to Regex.

Expression
Required. String expression containing substring to replace.

Required. Substring being searched for.
Replacement
Required. Replacement substring.
Start
Optional. Position within Expression where substring search is to begin. If omitted, 1 is assumed.Count Optional. Number of substring substitutions to perform. If omitted, the default value is 1, which means "make all possible substitutions."

I wan't a method with which to find a string within another string. It should return the position of the first occurrence of the substring. (In VB 2008 !)
View 2 RepliesIs there something I am missing to pre-check a string for a certain number of instances of a substring? Example.
"I am a test string, I will be searching this string later. I will be checking for every instance of the letter "i" and return the number of instances of that letter."
If I wanted to return an int for how many times i occurs in that string.
I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'.
I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc....
I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way.
Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either.
I've settled on using a List(Of), and I've borrowed from Dan's code to iterate through the list.
How do I make a regular expression to find a substring within a string that looks like: |sdrt446-7fdfs23| ? The number of characters and types change. So I need whatever in within the | |.
