listbox in VB - Overclock.net

guitar22891 · 08-25-06

Well I have 2 listboxes right? so how do I make it so when I select a thing from the listbox1 it displays the list pertaining to the item selected it in listbox2. And if I selected a different item

from listbox1 it displays a different list in listbox2?

I know nothing of VB, but in Java you generally use an array to specify the contents of a list box, or button labels or whatever. You also use events to catch certain commands and stuff.

I would make an event handler so that when an option in list1 is selected, it allows list2 to display the array of items that corresponds to the choice in list one. Not the greatest explanation, but I'm not exactly sure what VB can do.

Sort of:

list1 list2
option1 -> arrayOfOptions1
option2 -> arrayOfOptions2

I figured I have to use an array but I really don't know the code to do this...

Is this VB6 or VB.NET?

Here's a simple version of the code I've used in the past for VB.NET. It might also work in VB6

Hope it helps.

Code:

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.FillListBox1()
        Me.ListBox2.Items.Clear()
    End Sub

    Private Sub FillListBox1()

        With Me.ListBox1
            .Items.Clear()
            .Items.Add("List 1")
            .Items.Add("List 2")
        End With
    End Sub

    Private Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged

        Select Case Me.ListBox1.SelectedIndex
            Case 0
                With Me.ListBox2
                    .Items.Clear()
                    .Items.Add("List 1 - Item 1")
                    .Items.Add("List 1 - Item 2")
                End With
            Case 1
                With Me.ListBox2
                    .Items.Clear()
                    .Items.Add("List 2 - Item 1")
                    .Items.Add("List 2 - Item 2")
                End With
        End Select
    End Sub

End Class
