listbox doubleclick

how do i create a function that executes when an item in a listbox is double clicked on? it has to be a double click on an item and not anywhere in the listbox. the item index or name has to be passed as an argument of the function.

thanks.

Simply , like this :

VB Code:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.ListBox1.Items.AddRange(New String() {"marvinklein", "Edneeis", "Pirate"})
    End Sub
 
    Private Sub ListBox1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.DoubleClick
        Dim itm As String = Me.ListBox1.Text
        If itm <> "" Then
            'Do your stuff here 
            MsgBox("You doubleclicked " + Me.ListBox1.Text)
        Else
            Exit Sub
        End If
    End Sub
