Put Into An Array Or Arraylist?
Jun 18, 2012
Here's my code
Dim allelementds As HtmlElementCollection = MbFacebookBrowser.Document.GetElementsByTagName("span")
For Each DD As HtmlElement In allelementds
If DD.OuterHtml.Contains("resource") Then
TlsResourceComboBox.Items.Add(DD.GetAttribute("InnerText"))
[code]....
As you can see im currently using a combobox as a type of a list which uses index to give certain labels their text I know that there are only 4 indexes when getting the inner text so how can put those 4 indexes into a sort of list without me using a Combobox?

I want to create an array of an array (or arraylist of an arraylist) to hold strings.I want to fill an array1 with string values Then add this array to array2. - but only taking up 1 row in array2 e.g something like array2(index)=array1 Then clear array1 then loop through this again with different data, and add it to the array2.so will end up with something like
array2(0)... contains a collection of array1 data
array2(1)... contains a collection of different array1 data
.. and so on
i think i need to make new instances of array1 each loop, but not sure.I dont mind if it uses arrays, or arraylists, or lists, or structure of arrayslists?

After gathering the Machine names on the (sealed) LAn i am then getting the ip addresses, MAc address and Macine User name of each machine on the LAn..These details will need to be accessed seperately for use in the security testing and i am unsure how best to store the active data (though eventually in a database) Am i best to create a Multidimensinal arrayList or array(bearing in mind that all the data is convereted to "String" (arrays can only store one data type??) The data found on the live network is allways changing making an array a difficult choice? I have read some tutorials mentioning making a structure with the data and storing this in an arraylist but i dont know whether this will make accessing the individual data items (ip,MAc,HostName etc) a difficult procedure?

Dim iArr As Array For Each iArr In m_alTabell 'ReDim myArr(16, 11) If i dim iArr(0,0) as string I could do this.ii = ii + 1 iArr(i, constanter.colNames.colValue) =m_objList.GroupItems.Item(ii).ListItems(i).Value'm_alTabell.RemoveAt(ii - 1)'m_alTabell.Add(iArr)
[Code]...
I have a problem with this code. m_alTabell constists of 10 twodimensional arrays. I have some data in them from the beginning. Now I want to add data in each iArr in a_alTabell. This works fine on the first one. But then the trouble starts. It just keeps overwriting the first iArr in m_alTabell. So if i could redim iArr it would solve the problem but i cant do that course it needs to be declared as Array and not "Dim iArr(0,0) as string" since that couses other problems.

Is an ArrayList the same thing as a Structure (i.e. 'array of records')? If they're not the same think, what't the difference?

I am trying to split an array into a jagged array for easy manipulation, but I am having a bit of trouble with the Copy method of Array.This is what I have:
Dim masterData()() As String = New String(splitCounter.Count - 1)() {}
For i As Integer = splitCounter(0) To splitCounter.LastIndexOf(splitCounter)
Array.Copy(ServerResponse, splitCounter(i), masterData(i) = New String(), i, splitCounter(i

there are any nifty in-built .net methods that can essentially return either the number of occurrences of each element in an array, or simply return the modal value.

I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.

What 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

I have an arraylist (arrFirstArry) which I use to populate another arraylist (arrNoDuplicates) preventing any duplicates from being added. This works fine. What I would also like my code to do is prevent adding any partial values which may exist from being added. i.e. my array is like this

What 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.

s there a difference between the arraylist in visual basic and arraylist in C#? I had to convert some C# code to VB and there is a call I make in a third party api that requires me to pass in an arraylist. When I do this in C# it works just fine, but when I do this in VB, I just get back a vaque exception from the api.
[Code]...
The exception I get is very vague and comes from the API. All i get is, "ARException Occured".

I am trying to create the following program Store in a 1d array a set of 5 place names and in a 2d array the distances between the places. Ensure that the order of the places is the same in both arrays. When the names are places are input the distance between them is displayed. If they are not both in the table a suitable message is displayed
Dim town(1 To 5) As String
Dim Dist(1 To 5, 1 To 5) As Integer
Dim First As Integer
[CODE]......................
I think the best way forward is pass a parameter to the function findnumber.

I am trying to make a little program for fun and I don't know OOP that well. Since this part of the program is going to be large in comparison to everything else, I want to make sure I don't half ass it.
I need,
50 states
each state having multiple schools
each school having multiple players
and each school having 1-4 coaches who may or may not have awards
I only posted a couple classes since I should be able to figure the rest out off of these two. The award class properties will be changed later. How do I make a new coach that has x awards? I am confused with this part. If I did not explain something clearly please let me know, I want to make sure I get this program started off the right way.
Public Class Coach
Public Sub Main()
Dim coach As ArrayList = New ArrayList
' coach.Add(New Coach(1, "Billy", "Bob", 0, 50, ???))
End Sub

I'm having some trouble adding an object to an arraylist.
Basically the object has two properties (file id/name), but I can't figure out how to assign those properties. During runtime it errors out with public member on the object not found.
Private QueueList As New ArrayList
Public Sub Queue(ByVal FileName As String, ByVal FileID As Integer)
Dim QueueObj As New Object
[Code]....
I'd also like to know how I can do a loop on the arraylist and access the two properites on each record.

I am trying to create an arrayList of people. The variables, or arrays are; first name, last name, age, DOB. I am wanting to load all that into one arrayList and dataBind it so it would look like [code] Loading it into an ASP DataList. SO Fname + Lname + age + DOB are loaded on the same line/index. Not sure how to go about this. I'm sure it's an index issue..but not sure the thought process to even begin to load these elements into the "0" element, then the "1" and so on. Not puling the information from a database, just preset arrays/arrayList. ANY suggestions? ( I have it so it is dataBound to one arrayList entry as in [code] This works fine. But if I wanted to add the last name to the first name on the same line...that's were I am not seeing the connection.

Not quite sure how to attack this one. If I have an array list how would I go about elminating duplicates but adding the values of those items together. In other words if I have one item that has a id of 9000 and a quantity of 5 and another item that has the same id of 9000 and a quantity of 10. How would I eliminate the duplicate but add the quantities

I've been trying to solve it for more than a week, but I need help on putting an arraylist inside a listbox.
That's what the GUI should look like in the end, all the information has to be saved in an arraylist; I should be able to add a new customer; click on a customer entry to edit it.
