View 1 RepliesI 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?

how to convert an ArrayList to an Object.
If I have the following:
Dim errorArray() As Object
Dim errorList As ArrayList
How do I convert errorList to errorArray() in VB.Net?
I previously asked a question about my meeting planner app, and how to delete a specific entry in the array. Someone had the interesting suggestion of using a ArrayList, instead of a normal array. I am attempting to learn ArrayList, but to no good result. I can't even get the ToString method to work correctly to write what I want it to into a text file.[code]...
My plan is to have each of those three fields to have their own entry in the ArrayList, but when it is saved to text file, those three fields are comma delimited to a line for each appointment. Of course when the text is loaded, it will have to be converted back. Can anyone point me in the right direction or have any other method of going about this with the ArrayList?
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?
View 1 RepliesDim 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.
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?
If I want to store a list of names ie. "David", "Frank", "Chris", would it be better to do:

Also, what is the difference if you put the () with the variable name or with the type? I see sometimes

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?

View 1 RepliesI 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.
View 7 RepliesI 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.

I have an ArrayList named Invoices populated with objects of the class Invoice.
I'd like to data bind this to a ListBox so that as the contents of the ArrayList are updated and changed the ListBox updates. I've implemented a .ToString function on the Invoice class, I just don't know how I'd go about binding the ArrayList to the ListBox.
I am developing a VB.NET ASPX file which is currently working. But now it errors cause I added this one new input parameter which is a dropdownlist. The dropdownlist works properly now. Its source comes from a SQL DataReader. But hte problem is that the fields that the user should see are different from underlying values. So I want to create a 2 dimensional array list or somehow create a mapping as follows[code]...
View 1 RepliesWhat 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 am using Visual Studio 2005 and am writing a SSIS package. In the package I have a VB.Script that looks at a directory on a server and creates a list of the files. I then have a store Proc that looks at a table and gets a list of files that matches the files in the first array. The result is a fullresultset. The next step I need to create a 3rd array that only contains the rows from the first that are not in the second. However, I am getting the following error. Error: The script threw an exception: Unable to cast object of type 'System.Object' to type 'System.Collections.ArrayList'.

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.

View 8 RepliesThe following image or RTF file illustrates how I'm trying to transform an input Byte array into an output array of Booleans. This is basically what I have listed below. figure out how to get from one array to the next while shifting values of bytes within 8 byte groupings to shift low order to high order or vica versa. What I mean by that is best seen by looking at the illustration of actual input an required output. The reason for this is that the hardware devices have registers and the display which can be seen in the links above needs to convey the disabled sensor cable cell locations.
