Code:
Imports System.Net

Public Class Form1
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        lstboxoption.Items.Add("IP Address")
        lstboxoption.Items.Add("Source Code")
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        If lstboxoption.SelectedItem = 0 Then
            Form2.Show()
        End If
    End Sub
End Class
I want to make it so that when a user clicks on the first item which is "IP Address" to show Form2, I'm not sure if I'm using the SelectedItem correctly. I keep getting a "conversion from string to type double is not valid" error.
