Dynamic String Trimming Based On Character?
Jun 2, 2011I have an array filled with values from Excel cells. Each of the values is a concatenation of two things separated by a pipe, like "Machines|MachinesCode"
I need to, as I fill this array, strip out the pipe and everything in front of it so that the array being filled is only filled with the "MachinesCode" part of the cell value, but I haven't had much luck finding how I should do this. Each cell is dynamically filled and will never have a set length, so I can't set a trip by a particular number value of characters in the strings.
This subroutine is what I'm using. I am filling array FieldArray with another array (ExcelArray) currently holding the concatenated values.
Public Shared Sub PopulateFieldArray(ByRef FieldArray() As String, ByVal iFieldCount As Integer, ByVal ExcelArray(,) As Object)
Dim iIndex As Integer
For iIndex = 1 To iFieldCount
FieldArray(iIndex) = CStr(ExcelArray(2, iIndex))
Next
End Sub
But I don't know what to wrap around the CStr Excel array to cut off the pipe and all values before it while I fill FieldArray.

How To Split String Based On Set Length Of Characters
Nov 2, 2011MVC 3. Vb.net. Part of my app generates PDF files using Itextsharp. Some strings are too long to go onto the background image correctly. So I basically need to split this string when its over 26 characters long and when it splits it cant split in the middle of a word. from there I will use newline to add the string to the right to the next line... I did start bulding the function that I will pass the string into test for length and then pass back the string after it finishes.
Private Function stringLength(ByVal _string As String) As String
If _string.Length < 26 Then
_string.Split(

.net - Replace Content In A String Based On Regex.Matches MatchCollection?
Mar 5, 2009I'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.

VS 2010 : Fill A "gap" After Removing A KVP In A Sequential String Key Based Dictionary?
Jan 2, 2012I need to remove an instance in a class for which I also created a dictionary with a string key type. Like this...:
vb
'Declare dictionary
Public PersonsList As New Dictionary(Of String, Person)
'At the bottom of frmMain.vb
[code]....
As you see, I end having 120 instances of the class Person, each assigned with a string key consisting in "student1" to "student120".
At other parts of the program I repeatedly refer to PersonsList("student" & n) to set values at those class entries, mainly with a For n ... Next block.
Now... I need a routine to remove one of those instances for good, including its entry at the dictionary, so my first bet is this...:
vb
Public Sub ExpellStudent(ByVal student_index As Integer)
PersonsList.Remove("student" & selected_student_index)
students_count -= 1
End Sub
I assume this is good enough to remove the KVP at the dictionary AND the class instance proper... right?Well, even if that is ok, I foresee one problem... Let's say I removed "student46". Next time I run a For n = 1 to students_count I would bet that I'll receive an exception due to having a gap at "student46" KVP... and that without saying that students_count will be 119, so it will never reach "student120".In short, I need a way to reassign the KVP of the now 119 Person entries, so they're consecutive again (I don't care about them changing their string key values), so I still could use my For n = 1 to students_count ... Next blocks without problems... but I cannot figure out how.
Extract String From String When Only Beginning Of String?
Aug 12, 2011Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything
