View 2 RepliesC# - Prepend A Substring If The Source String Does Not Begin With The Same Substring?
Oct 10, 2011I'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:

How To Extract "+ From A Group Of Substring
Aug 13, 2009may i know how to extract "+ from a group of Substring? i tried the indexof method like i1 = s1.IndexOf(" "" ") but its giving me error probably because the compiler thought its unclosed clause.
I am trying to grab the "+ from the string : +CMGL: 1,"REC READ","+6596231118",,"09/08/13,00:17:11+32"Fire alert So this will actually grab the string starting from the "+ and including the handphone number until the next" , like this +6596231118 I have tried the substring method but it wont work because of the memory location over at the +cmgl.
VS 2010 Using Substring To Extract Paragraphs?
Aug 4, 2011I have the following code which seems to work as intended.
From what i can tell is that Size is not the same as the amount of characters in a particular string, Is Size a size as in Bytes,Kilobytes etc?
Edit: Ive attached a PDF showing the output from this code. Which as you can see shows the wrong output and the sentence's go off of the side of the pdf.
So from what i can see is that tempPage.width (Which is 612) is some how wrong, because 612 characters goes off the side of the PDF Doc.
Public Sub writeParagraph(ByVal text As String, ByVal fontSize As Integer, ByVal align As Char)

This was working as intended but then i realised "What if it was possible to generate 1 paragraph at a time and then check the yAxis of the page and if it has been met or exceeded then continue to write the paragraphs on a new page".
Im having a blank brain day lol , I cant seem to work out the correct calculation to extract each paragraph 1 at a time and add it to the arrayList.

Getting String.substring(N) Not To Choke When N > String.length
Mar 10, 2010I'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 2 RepliesFind A Substring In An ArrayList, StringCollection Or List(Of String)
Jun 7, 2010I'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.
