Change Order Of Items In A List Sequentially?

Jul 26, 2010

I want to rearrange a list of items in different orders for few times; ie: the 2nd in the list becomes the 1st & the previous 3rd becomes the 2nd, ... then the Last one becomes the penultimate one.In the next round, the 3rd of the original list becomes the 1st & the 4th of the original becomes the 2nd and so on. (That is, each item moves one rank above & the Top one goes to the Bottom)Given below is an example.Here, I took only 6 items & rearranged for 5 times only. (I should be able to use several Items and to rearrange for many times).The Original List:

(1) Alpha, (2) Beta, (3) Gamma, (4) Delta, (5) Epsilon, (6) Zeta
2nd List:
(1) Beta, (2) Gamma, (3) Delta, (4) Epsilon, (5) Zeta, (6) Alpha

Adding Items From List Box

Jan 28, 2010

I'm learning how to add items from a list box to a combo box. I'm trying to follow what's going on in the function loop and comparing a boolean and selected index. I can see that it's comparing the item chosen to each item already in the combo box to make sure that it's not already there. If function finds that it's not in the list it sends back that it is true that the item is not in the list.

It then continues to the statement that adds item to the list. The code for the double click event is working fine and items are getting added to combo box. However, the code for the add button isn't functional. I'm not seeing why it doesn't work? I coded out the original code, and replaced with something I thought might work but it still isn't functional. [Code]

Adding Items To A List (of Object)?

Mar 28, 2010

I have some code that adds items to a List(of Object).

Here's my original code

Dim BeaconStoryList as New List(Of My.StoryType)
Dim BeaconStory as New My.StoryType
Dim NewStories() as New Foriegn.StoryType = GetStories

[Code]....

But as soon as the code assigned "Chicken" to BeaconStory.Title, then BeaconStoryList(0).Title would also change to "Chicken".

With my second version of the code this did not happen.

It's as though it was placing pointers into the elements of the array rather than values. If that is the case, however, then why does my second version of the code work - I'm still passing in the same thing - aren't I?

Adding Items To List Boxes?

Oct 19, 2010

I'm using the free version on Visual Basic 2008 (through school).The assignment is to populate a list box from user input text. The textbook only talks about populating a list of known items.ex animalListBox.Items.Add("dog") Which works just fine, however, we don't know what the user will input.

So, how should I be thinking about this?

Adding List Of Items To Array?

Apr 14, 2010

I'm still learning VB.net and there is a bit of code I have added which is an array and I want to add a list of items to the array. If that makes sense. I have 6 classes two have arrays.

Here is the code from one of the classes
Public Function getItems() As Array
Return _LevelItems
End Function

How would I add the item list to this? Where do I put it? Like underneath it or in the items class? That code is in the Level class.

Adding A List Of Items To A Listbox From A String?

Aug 18, 2011

I have a small program that talks to a server, grabs the content from a website using a php webscraping program and then places the results in a listbox as a string. My problem is taking this string and creating a list from it. Each item in the string is followed by a | (pipe). I have included the code that I've tried below:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str As String
Dim start As Integer = 1

Adding Items To List Results In Duplicates?

Jul 29, 2009

I have this code to return a list of fund sources for our organization.

Dim FundSourceList As New List(Of FundSource)
Dim fs As New FundSource
If results.Count > 0 Then[code].....

The problem is that when I loop through the resulting FundSourceList all it shows is the last value. For example, if I have three fund sources (state, federal, athletic), then when I use this code to loop through all I get listed is athletic, athletic, athletic.

For Each FundSource In FundSources
Debug.Print(FundSource.FundDescription)
Next

So I change the code to this. I moved the creation of the fs variable inside the loop.

Dim results = From result In dsResult.Tables(0) Select result
Dim FundSourceList As New List(Of FundSource)
If results.Count > 0 Then[code]....

This works fine but now I'm creating a new class over and over again. It seems a little inefficient to me. Can I not create the class outside the loop and use it over and over again?

I'm not sure where I'm going wrong with this. it's supposed to let the user add scores to the list, then calculate the total, average, and count. However, it doesn't let me add more values to the list. Any help whatsoever would be awesome! Keep in mind, I am new to VB and programming languages, and was just playing around with code hoping for any sort of positive result, and therefore some of the code may not be necessary, or make sense.

Adding A Umeric Value To Text In List View?

Mar 12, 2009

I started working on a product list with an array of products, these products are in a list view. You click the item and it is added to another list view and removed from the one it is curently in. I had it suggested to me and it sounded neater. I had no problems tinkering with codes and getting it opperating properly. But, What I am having trouble with is putting a cost to the product.

The idea is that the user would select products from the list and then they will be totalled together which is why it is important to be able to get the cost in there but not actually visable.Athiest advised me of a method used in combo boxes, because i was originally working with combo boxes. So I tried using that for my needs in a list view. Turns out to be a little more awkward than I thought. I get an error while trieing to add the item to my list box because I havent "declared" it.

Why Is List.add() Adding Items To Object AND Source Object As Well

Jun 15, 2011

I need to be able to add elements to a copy of mylist.testlist without modifying the global mylist object. (Which seems to be happening via the below code.)When I am working on x, which should be a totally separate object, mylist is getting modified as well. How can I fix this? I have worked with lists extensively and never seen this behavior before. I have tested and reproduced the problem in .NET 3.5 and .NET 4.0 on Win 7 Pro 32bit.

Source Code:

Public Class Form1
Public mylist As New test

Set The Text Of List Items In Windows Forms?

May 28, 2009

how to set the value of the text that is displayed for each item of a list control, such as a checkbox list, but really this applies to most list controls, not just the checklistbox control.

I have a checklistbox control,

Friend WithEvents clstTasks As System.Windows.Forms.CheckedListBox

that I usually want to populate with a list of task names. I call the add method to add a Task object to the list. I know that if I override the ToString method, whatever value is returned by that function will be displayed as the text for the list item.

However, in rare situations, I want to display something else other than just the name. For example, perhaps I want to display the name and the value of another property, such as the value of the Boolean property "Optional" shown in parenthesis following the name.

The best that I can think of is to define a property which is set in the GUI layer and then used by the ToString function to determine how it should behave when called. If the controlling property is set to one value, the ToString will return the Name, else it will return the Name followed by the value of the Optional flag. This seems a little disjoint a kludged to me.

The other alternative which seems a little overkill is to define a new class which inherits from Task, for example TaskOptional, which overrides the Tostring method on the base class. In this subclass, the ToString function would return the Name/Optional flag value. However, this, too, seems a little nuts to have to come up with a new class just to modify how the text is being displayed in the presentation layer. I feel that I should be able to control this in the presentation layer without changing the business object or creating a new derived object.

What is the best way to accomplish this?

For Each CurrentTask As Task In _MasterTaskList
clstTasks.Items.Add(CurrentTask, True)

DB/Reporting :: Taking Text Boxes And Adding To A List Box

Oct 15, 2008

I'm writing a database program that will take various information from the user via text boxes, then save them as a *.txt file. I've already figured out the majority of that business. However, I'm having trouble programming a ListBox.

The ListBox needs to accept three pieces of information from 3 Text Boxes, then concantenate them when a button labeled 'Add' is pressed and scoot them to the ListBox (lstshowresults) while clearing the three boxes at the same time.
