I want to get items into the ListBox from Database on FormLoad.
My code is:

Dim qry As String

I am already having three models in database that has to be loaded in ListBox on formload.
My program is working and doing everything it is supposed to do outside of two things. My program is supposed to take the items that are under 5 items and show up in a listbox saying they are low stock by clicking file and then display low stock items. The other problem I have is that I am supposed to show everything in the inventory that has a retail price given to it in the other list box that is blank on my mainform. The attempt I have made on the low stock inventory makes the program go into debugging mode.[code]

I am displaying four fields from a access database. This code displays the records in listbox4.
Me.ListBox4.DataSource = DB
Me.ListBox4.DisplayMember = "fldRecNo"
Using the doubleclick event, I would like to display on a label the record number that I doubleclick.

I just starting coding in VB.net about two weeks ago so I'm still a begging and I learn best by seeing working code and then adapting it to my situation. That being said, I need help displaying table entries in a listbox. I've successfully created a database in my test application, added it to my Data Sources and used a drag / drop method to add Datagrid View & Details (labels & textboxes) to my application for testing purposes. Now I want to try and display table entries in a listbox.
Example Database:Table: Contact
- ContactID (autonumber) [primary key]
- FirstName (text 50 limit[code]....
Also is there any benefit or down side to creating a database in MS Access, create the relationships & tables, then attaching that database to my application or is it better to create the database in the application like I did in the example above by using the Add New - Service-Based Database option?
Private Sub DisplayList(ByVal CusRef As Integer)
Dim ConnectionString As String
Dim SQLString As String
Dim TitleString As String
Dim conn As System.Data.OleDb.OleDbConnection

So that works, but how do I display multiple things, CustomerID & CustomerName on the same line?
I can't get it going, it only puts my CustomerName under the ID
I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

I was writing a program that would save the contents of a listbox to a database and wanted to reload the users' choices when the opened up that particular row again. My first thought was to do it with two for loops, just as I used to do in VB6, but I thought there must be a better way to do it. And there was. Sort of. It basically involves using the SelectedObjectCollection class.For this demo, you'll need a listbox called Listbox1. Set selection mode to something other than "One" or else it won't work as expected
Dim items(0 To 3) As String
items(0) = "One"
items(1) = "Two"

I've been working on a little project recently which is a music player (unoriginal I know, but I'm just learning ). Basically, I want the items that have been added into the listbox to be remembered for the next time the application is opened so that you don't have to re-add the items. The items show up like this (because they are added from my documents): C:UsersEthanDocumentsMusicCage The Elephant - Aint No Rest For the Wicked.mp3?

View 2 RepliesI am using a listbox that is filled with a list of items from Database. When I am deleting an item from the listbox it is has to be deleted from Database, and that is all working fine.The problem is, even after deleting the item from the listbox, it is showing in the listbox, I have to close and restart the app to get the deleted item off from the listbox.
Is there any way to remove an item from listbox at the same time? I don't want to use timer to refresh is there any other way to refresh the listbox items???
I am making a program, and I have a listbox which will contain A big list of file Paths. I have two buttons Add and remove. Adding items is easy and I have done this.

I am wondering how i would go about taking multiple items (randomly) from a listbox and displaying them in a label!Now this listbox wouldn't have to be visible, maybe i can do it without it even being a listbox?I want to have 25 labels and each one recalls a random value from the list (doesnt matter about being unique and the list will contain about 20-30 items)Im just a bit stumped on how to do it as ive done some looking into it but most people are asking for randomized numbers or unique items where as i need randomized items from a list which aren't unique!

I googled to find how I can change the items forecolor or backcolor. I want the items containing "Unmatched" to be one color and "Matched" another.
basically i had this problem before which i fixed with this code!
'REMOVE TIME
If ListBox1.SelectedIndex <> -1 Then
Dim Box As MsgBoxResult = MsgBox("Are you sure you want to remove this time?", MsgBoxStyle.YesNo)

It worked perfectly, all ive done to my code since is change the way the listboc is loaded / saved, it now comes from a .txt in My Documents rather than the C drive.
It now only deleted the top value of the group selected int he listbox and not all of them as it did before.

So I'm using the following code to add items into my list box, and I'm trying to get it to check the contents of the list box as well.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
ListBox2.Items.Add(New LBnfo With {.v4 = RadioButton6.Checked,
[Code] .....
But when I try to compare the two:
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
It doesn't show the message box even when the character actually does exist. I believe the problem is that I never do add the item really. I just use, "Return Me.character," which is assigned the value of Textbox3. So I just need to figure out how to check Me.character before returning it.

How would one go about checking a listbox's items for duplicates? Basically I need to write a program that displays the teams from a text file provided by my instructor, in alphabetical order. I can do that, but what I can't figure out is how to prevent the For loop from adding a duplicate team. What I'm envisioning is:
If teams(i).name is not in lstTeams.Items Then
lstTeams.Items.Add(teams(i).name)
End If
I have a program that compiles and works so far, except for the above problem and my alphabetical order (which I can probably figure out on my own:
Public Class danbrockteams
Structure team
Dim name As String
[Code]....
This works except that my listbox is filled with the team every player is in rather than just listing all possible teams. Not exactly looking for someone to just give me the answer, as I understand things best when figuring them out on my own, so I suppose a hint is what I'm really after.
