[tommygrayson]

Hi all!

I need help getting the value of a selected listbox and transfer it to a textbox.text. I tried everything but seems that I am only getting frustrated.

There's something definitely worng with my code:

Imports System.Web.Mail
 
Public Class WebForm1
    Inherits System.Web.UI.Page
 
#Region " Web Form Designer Generated Code "
 
    'This call is required by the Web Form Designer.
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
 
    End Sub
    Protected WithEvents Button2 As System.Web.UI.WebControls.Button
    Protected WithEvents ListBox1 As System.Web.UI.WebControls.ListBox
    Protected WithEvents ListBox2 As System.Web.UI.WebControls.ListBox
    Protected WithEvents ListBox3 As System.Web.UI.WebControls.ListBox
 
    'NOTE: The following placeholder declaration is required by the Web Form Designer.
    'Do not delete or move it.
    Private designerPlaceholderDeclaration As System.Object
 
    Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        'CODEGEN: This method call is required by the Web Form Designer
        'Do not modify it using the code editor.
        InitializeComponent()
    End Sub
 
#End Region
 
    Public Sub AutoGen(ByRef EmailMessage As String)
        Dim RanInteger As Integer
        Randomize()
        RanInteger = Int((3 - 1 + 1) * Rnd() + 1)
        Select Case RanInteger
            Case 1
                EmailMessage = "Dear Mr. Yehhui," & _
                               "<br>" & _
                               "<br> USCNC has cheap and efficient products! Please visit our site!" & _
