I have two arraylists that contains links in one and the root url in the other. Sometimes the lists dont equal in number and I would like to iterate through the links list and if it contains a matching root url add it to a third list but also avoid any duplicates. I tried this but am not getting consistent results.

For Each link As String In urls

Perhaps there is another way; basically the part in post is a link to a page and contains the root url( which is link in urls). After extracting all these I need to ensure the 2 lists match.

Hi, I'm trying to develop a VB GUI that allows the user to download assemler code (Hex file) into microcontroller via a LAWICEL CANUSB.

I have two arraylists, and I would like to have a new arraylist with only the uncommon items. Is this the "best" or at least decent way to do it?
[Code]...
OK, so I am creating a bit of code that will allow me to randomly pick one "card" from a "deck", delete that "card" from the deck, and repeat. I found in all of my research that vb.net has the arraylist that is supposed to be very simple in these situations. However, when I try to populate them with a For Each statement, I only get odd numbers in the array list. What am I missing?
Dim a As New ArrayList

I was trying to use ArrayLists with My.Settings but I can't seem to figure out how to get them to work.If I make a setting called "Words" and make it an ArrayList without a value, the program has an error every time I try to run it. If I try to give it a value in the project properties window it always gives me an incorrect data type error. Besides, I don't want it to have a value, I want it to be blank such as when declaring a New ArrayList. The only way I can get an ArrayList My.Setting to work is by clicking in the Value box, clicking the "..." button in the corner and adding some kind of Object with the add button. This automatically puts some kind of wierd object in the first index of the array list. If I don't convert Item(0) of the arraylist to a string then it also gives me an error when I try to read it. As a string it comes up as System.Object. Even though I can use the my.settings.Words ArrayList with an object in the first index, how can I get the setting to start off blank without having to constantly avoid the first index?
View 10 RepliesI have been tempted to use List(Of T) in VB.NET instead of ArrayLists by someone-who-must-not-be-named-Robinson.Essentially, what I need to store are three things: One string, two integers, and maybe two booleans. I liked using ArrayList, because it treated all its elements as "Objects" so I didn't really have problems storing that variety of elements.But now I have been thinking on using List(Of T). But how do I do to store that variety of elements of mine? I have been thinking on making a Structure holding the five elements.Sounds like a good idea? I heard somewhere that Structures are expected to have a short life. But I fear I will be having my structures for... forever, as long as my app lives. That makes any difference? Finally, what if I needed to create... dunno...... 125000000 Lists, each containing a structure? Is that possible (and good)?

I have three arraylists (datasets and subsets) that I need to combine into one arrraylist so I can databind it to a repeater control and then present data to the user. As far as I know, you can only bind the repeater with one datasource (please correct me if this is wrong) that's why I'm combining these arraylists.Each arraylist has an ID from the database which I can use as a datakey to keep the data aligned. How do I combine these lists?
View 4 RepliesI have searched high and low for a solution yet still no luck, I have two arraylists populate with FileInfo and I want to compare the two and write the duplicate (matching files) to a listbox.Here is how I have populated the arraylists but in terms of the comparison I have not found anything that works:

I am trying to convert an algorithm to use them in order to save memory. However, I am struggling to achieve error-free code while using "Strict On".

It works when I do not use the Strict option. How do I improve the code to compile error-free?
Background: I'm writing a application that will allow users to enters items on a form using textboxes, radio buttons and checkboxes. I then take each input item and write it to it's own arraylist. After the user is all done entering data the information in the arraylists will write out to a single .txt file.

I have an XML file, with a rather large structure. I'm pulling several entities out of it throughout several systems, and its dynamically updated once a day. I'm using a Linq Query that is exhibiting odd behavior, its only returning if the first entry in the site tag matches the search-pattern. If its number 2 or 3, it fails to return anything. Why would this behave that way?
The following function written in VB handles pulling the data
Public Function xmlSchoolListBySite() As IEnumerable
Dim doc As XDocument = loadXML()
Dim loadedPrograms As IEnumerable(Of XElement) = From c In doc.Descendants("Organization") _
Where c.Descendants("site").Value = MySite.Site.s_Url _ 'contains Result.RawURL.tostring() formatted

I have several label boxes on my design form that all share the naming convention lbl_#.text where # ranges from 1 to 60. I want to make a loop that iterates through each lbl_#.text adding some incremental value, let's say multiples of 2 for this question's theoretical purpose.Something such that the end result would amount to the following:
lbl_1.text = "2"
lbl_2.text = "4"
lbl_3.text = "6"
lbl_60.text = "120"
I'm not sure how to access each of these labels through the coding side, I only know how to explicitly mention each label and assign a value :/
I am writing a simple XML web service and want to return raw XML. I am doing this by creating a string literal that represents the XML.

If I have a complex structure which contains properties which are both simple and complex types, how can I iterate over all the properties of this structure and any child properties which are not simple types?
I have a complex type called file, which contains lots of string properties and some which are other complex types which contain similar structures, eventually the whole structure breaks down into strings.
At the moment my code looks like this:
Dim file As New File
Dim props() As PropertyInfo = file.GetType.GetProperties()
_propList = New CheckBoxList
[Code].....
This works, but it is ugly and I am not at all happy with certain chunks, specifically the type comparisons to establish if this is a date, string, decimal or boolean which are the potential low level types which I want to get out.
In C# it would seem these type comparisons are easier, but i seem to have to create an instance of a given type to be able to use GetType to return its type.
