random number guessing

[clubberlangMayo]

hi guys, writing a code in my first term at vb 2010, ive to create a guessing game, generate a number between 1 and 30 and let the user guess it. i must give hints along the way and record the amount of guesses made. i have the code written and working. my problem lays with changing the range. if i change the range to any other number, when i press enter it keeps givin a new random number each time.
Public Class frmMain

Public min As Integer
Public max As Integer
Public randomClass As New Random
Public num As Integer

Public X As Integer


'Dim X As Integer = Int(X * Rnd())

Dim msg As String
Dim title As String
Dim style As MsgBoxStyle
Dim response As MsgBoxResult


Private Sub frmMain_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    min = 1
    max = 30

    Randomize()
    X = randomClass.Next(min, max)
    'X = CInt(Int(30 * Rnd()))
    lblMin.Text = min.ToString
    lblMax.Text = max.ToString
    For i As Integer = min To max
        ComboBox1.Items.Add(i)
    Next

sorted myself

num = ComboBox1.Text
        Label2.Text = X

        If ComboBox1.SelectedIndex = X Then



    i should have had num = X.  i wanted to get the principals of the game working before i ironed out the small issues
