This is bugging (my head is now switched off).I have two array's, one populated with dynamic elements and the other with static values. I am trying to filter out the values that i dont want from one of the arrays:
Dim arrFormItems As New ArrayList
arrFormItems.AddRange(arrSplitValues)
Dim arrItemsRemove As New ArrayList
[code]....
No matter what i do, i cant filter out the values. Tried the compare method as well..

I develop an application in vb.net and mysql server for data storage. I have a problem in my database I have something like 5000 codes stored like code, description, quantity, price, firm. I have a function to extract all the codes from database , it takes about 4,4269 ms to extract all 5000 codes with description and everything... in an arraylist. When I want to put all codes from arraylist in a textbox autocomplete, it took about 2305,400 ms and I think this is a big problem the function to put in textbox autocomplete all the items from arraylist:
Code Snippet:
Public Sub PopuleazaTextBoxDinListaCoduri(ByVal txtbox As TextBox, ByVal list As ArrayList)
txtbox.AutoCompleteMode = AutoCompleteMode.SuggestAppend
txtbox.AutoCompleteSource = AutoCompleteSource.CustomSource
Dim valoare
For Each valoare In list
txtbox.AutoCompleteCustomSource.Add(valoare)
Next
end Sub
This is one item from arraylist extracted from database in this format :
code4993 ->description of code4993(3 buc X 234 lei)
I don't want check if an item with a value exists in the arraylist,I want to know the best code for performance to get how many occurrences of the same item with the same value exists in an arraylist.

I am trying to count how many items are in an ArrayList and then save that into a Label variable that is updated each time an item's barcode is scanned.Information about the code below:rejectedList is the ArrayList that contains rejected parts.RejectedPartsNumberLabel is the label I am trying to update with the count from the ArrayList

Return (code.Length = 7 And IsNumeric(Mid(code, 1, 1))) Or (code.Length = 4 And Mid(code, 1, 2) = "NC")

I have an ASP.net web page with VB code behind linking to an MS SQL DB. On the web page I have 4 DropDownLists and 1 GridView. Each DDL is populated with a SELECT DISTINCT query on 4 corresponding columns from 1 table in the DB. What I would like to be able to do is: when any of the DDLs have their selected item changed the other DDLs are updated. Crude example:

Could not find this through Google or in SO questions.I have a checkbox listbox on my form. I want to filter my List by the list of selected Ids from that listbox that are checked, in SQL I would have done this like "Where TypeId In (1, 4, 5, 7)"... how do I do that in LINQ?
I feel like I am missing a really obvious answer, but cannot get it.
For argument sake... here is the what I have for sample data:
In Colors (List<of currentColors>)
ID, Name, TypeId
1, Red, 1
2, Blue, 1
3, Green, 2
4, Pink, 3
Selected Types 2 and 3 in CheckboxList: filteredColors

In my datagridview there are two dependent columns, one is category and the other is items. So I want to filter my item column list as per selected category. But the problem is that when I change the category wise data to datasource of items combobox, previous selected items names disappear because previous items is not in current datasource.
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 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.

I am trying to filter the results of a datagridviw using the bindingsource.filter method.

The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.
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?

View 5 Repliess 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.

The exception I get is very vague and comes from the API. All i get is, "ARException Occured".

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, ???))
