So I am trying to code something in vb.net 2010 which will have a list box. For example:
1) Apple
2) Pizza
3) Juice
How would I display Line number 2 or any other to the user - I tried doing it with a label box like this Label1.Text = ListBox1.Text(2) - does not work.
I'm trying to learn how to work with Collections list. In the past, if I wanted to create a list I would use an array and then save it to a text file after I was done manipulating the data via CSV.how to save things of different types to a list such as:
Name, Birthdate(as date), Salary
I know how to do this in an array but all the synapses aren't firing with the "new to me" collections list as collections lists are hard typed....
I have a ListBox containing a list of PDF files. The ListBox Click event displays the selected PDF file in a PDF control that serves as a type of preview for the user.
Private Sub lstPDFDocuments_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstPDFDocuments.Click
If IO.File.Exists(TempCurrentDocumentsBasePath & "" & lstPDFDocuments.Text) Then Me.pdfDocuments.LoadFile(TempCurrentDocumentsBasePath & "" & lstPDFDocuments.Text)
Me.pdfDocuments.setShowToolbar(False)
[CODE]...
I want the user to select a PDF file with a click and be able to preview the document and when the user needs a larger view of a PDF file the user simply double click on the list box. When clicking on any of the ListBox items the selected PDF file is displayed in the "preview" pane. When selecting the mnuDocumentsView option from the context menu strip the new, larger, form reflecting the selected PDF file is displayed perfectly. But, when double clicking on an item in the ListBox the Click event is executed instead of the DoubleClick event. For some or another reason I cannot use both the Click and DoubleClick events on a ListBox. I've tried seperating the DoubleClick event from the mnuDocumentsView click event, MouseClick, MouseDoubleClick, but no luck.
So I have a program that is supposed to support a small business. I have the work completed and the professor said it was correct but I wanted to go do a little extra.Basically, on the Order screen, you begin to type the name of a customer/supplier/employee into a text box and a list of names that fit the criteria pops up in a list box (lbMatchingAccounts). When you select it, you can hit enter new order and be transported to the Order Details screen to enter the new order.
What I wanted to do was to create a new list box (lbOrderId). What I want is to be able to select a person from lbMatchingAccounts and have all their Orders populate in lbOrderId.

I'm studying VB 2010 at uni and struggling with this assignment, I'm stressing now with one week to go before its time to hand it in and still not knowing how to do it (even though i've read the whole textbook!)
I have copied the instructions and the files I have been given.
1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above). Include suitable headings. Note that you cannot assume that the file contains only results for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.

View 2 RepliesI'm trying to figure out a way to sort the entries of a listbox... but in a different way instead of the obvious one (sorted property). First of all, I need to explain how the items are populated at first:

i am trying to create a list of list in that i would like to work on multiple accounts at the same time. lets say i have 5 accounts. every account has a seperate name. each account has a few fields. so i though of having a list of bookkeeping (with 5 accounts) and a list of accounts (with expense, income, tax, status, etc as fields). [code] and if the idea of using list of list works how do i loop through both lists.
View 6 RepliesI am using Visual Basic 2008 Express Edition and I am trying to set a listbox so it starts to scroll when it hits the middle point of what is viewable on my list. I also want to set it so the list is always visible so you when you reach the bottom of the list you can scroll down to the bottom but if you scroll back up once it reaches that middle point it will start to scroll up again.
View 2 RepliesI am trying to understand classes in VB 2010. I am a bit confused with displaying information from a list into a listbox.When I run the following code, the word collection appears in my list box. How do I drill down into 'hostnames' to display the info I want.

I am using Visual studio 2008, and I cannot get the listbox to generate the lists, nor can I get the calculate button to do work. I click it, nothing happens. BTW this is coded the way the instructor directed in the audio cast that was published for the class.
For some reason when I try binding the listbox to a datasource I put in (it contains a table of words to be used in the listbox), it shows me a + sign like it will allow my to drop text in but then it doesn't insert anything. Does this code not work for databound related things?

code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ListBox1.Sorted = True
End Sub
i am trying to put the contents of a listbox into an array using listcount so i can sort and manipulate the data in the listbox using linq. Everytime I try to use list**** it errors and tells me that listcount is not a member of systems.windows.forms.listbox It also gives this error or list. Here is the for loop i am trying to use to put the data into the array.
[code]
For i = 0 To displayListBox1.Listcount - 1
sorting(i) = displayListBox1.list(i)
Next
[code]
i dim'd i as an integer and sorting() as a string early in the program as class level variables. displayListBox1 is the name of the listbx containing the data I need to use in my LINQ inquiry.
Basically on form2 i have a listbox. And on form3 i have 6 listboxes. I want listbox 2 to equal listbox (a listbox on form3) my current code does not work Private Sub formAustralia_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

i can currently designing a account book program. I have five listboxs..with list1,list2,list3,list4 and list5.
FOr cost: List1 is the item code and list2 will be the price..
For sold out item : List3 is the item code and list4 will be the price..
For profit : List 5 = list 2's item price - list 4's price
What i wana do is, the item tat sold out will be listed in list3, so then list3 item will be compared to list1. if list1 item contains list3 item, therefore in the same index, list3 item price (list4) will be deducted by list 1 item price(list2) and shown in list 5. here is my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim totalitem As Integer = list3.Items.Count - 1

That was probably bad title, but I'll illustrate what I'm trying to do. I have a method in a class that I need to call several times. The method returns a List(Of String). I'm just grabbing some information from a database.
VB.NET
Public Function GetTestList() As List(Of String)
Dim int As Integer = 0
[code]....
Dim sDirs() As String
Dim i As Integer
sDirs = System.IO.Directory.GetDirectories(txtPath.Text)
For i = 0 To 5
ListBox1.Items.Add(sDirs(i))
Next
Lists the first 6 dirs it finds.
But how can i get the last listed dir into a varible so i can use its location?
I'm making a program to keep track of my gaming accounts and the characters that the accounts hold. So I made a class called "Accounts", made it a Datasource to a listbox.
[code]...
So this is what I have. What I want to do, is have 2 Listboxes on my form. one Listbox contains the list of accounts, and the other contains the list of character that the selected account holds. I'm wondering how do I do this through Bindingsource? I got the Account class bound to a Listbox's Datasource, now I need to figure out how to put the List(Of Character) to the other Listbox
I have a large list of keyword and I want include this list in a listbox .How can I do it?
I tried by paste the list in the collection control but by this way the listbox allow only a small amount of keywords.
I'm trying to get a listbox to populate a list of processes that are neither running nor in the "blocked" list. This code is in a timer, so it also checks if the process is already in the list.
For Each proc In Process.GetProcesses
Dim allowed As Boolean = True
For Each item In Blked.Items
[Code]....
It is strange because this is populating the list, but adding the same process over and over again, even though I seem to have the checks in there.
How to get list of installed programs into my listbox?
