Sorting/Splitting String In ArrayList?
Aug 20, 2010Basically, Im running an SQL query to the database, which obviously returns data in their fields. What I want to do is add each record into an ArrayList and split the string based on fields. I.E
CustomerID,Surname,GivenName etc
How do I go about this? so far I have:
alstData.AddRange(sLine.Split(","c))
sLine = the record from the database.
This doesnt seem to work, it just display's the data in one line with no split such as 20205SmithJohn?

How To Declare Specific String Range
Oct 6, 20091. In visual basic 6 when we want to declare a specific string range you use the following format: Dim SZ_ITEM_REF_NO As String * 16
When I checked, like vb6, the code it returned "end of statement expected"
2. When we wanted to have a specific format in the string in vb6 we use the example below:
SZ_ITEM_REF_NO = Format(Adodc2.Recordset!SZ_ITEM_REF_NO, "0000000000000000")
I have the following
myWriter.WriteLine(myReader(0).ToString
I tried to use it like this but it doesn't function:
Format(myWriter.WriteLine(myReader(0).ToString, "00000000000000000000"))

Find 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.

Copy The List Of Principal User To Arraylist To Use Arraylist.indexof?
Dec 1, 2011What I am doing is iterating through all the groups that belong to the top group (Generic reports). Then I take advantage of the GroupPrincipal.GetMembers(True) which will recurse through a given group name. I test to see if the user exits under that group and if true I put the group name in an arraylist.
I use the for each principal in GroupPrincipal.GetMembers to loop through each returned user to see if they exist.
Is there a way to put all the returned users Principal.Name from a given group in GroupPrincipal.GetMembers into an ArrayList? This would allow me to to use Arraylist1.IndexOf to search for user. Which would be much faster then iterating through a returned list using the for each construct.
Sub RetAllMbrs(strUser As String)
Dim oPC As PrincipalContext = GetPrincipalContext() '<- this is function somewhere else in the code

VS 2008 - Reading ArrayList In My.Settings And Add Another ArrayList To It
Sep 21, 2010What I need to do is read an ArrayList in My.Settings and add another ArrayList to it. The first think I'm trying to do is load My.Settings.Records into myArrayList. I'm not quite sure on the proper way to do this. I've tried things such as Dim myArrayList As ArrayList = My.Settings.Records, I'm not sure if I need New and I'm not sure if I need .Clone or .CopyTo.
Then I have another ArrayList myArrayList2. To get this into myArrayList I've done: [Code] Then to save it back to My.Settings I've done. My.Settings.Records = myArrayList. The problem is I keep on getting Object reference not set to an instance of an object error on the AddRange line. My.Settings.Records is definitely an ArrayList and it will sometimes = Nothing. The objects will only ever be strings.
