have to make some code modifications/adjustments also i ditched the module since i don't know how to make it work in .NET (highlighted the change):

Public Class Form1
Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

Public Sub New()
MyBase.New()

'This call is required by the Windows Form Designer.
InitializeComponent()

'Add any initialization after the InitializeComponent() call

End Sub

'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub

'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer

'NOTE: The following procedure is required by the Windows Form Designer
'It can be modified using the Windows Form Designer.
'Do not modify it using the code editor.
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
'
'Form1
'
Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
Me.ClientSize = New System.Drawing.Size(292, 273)
Me.Name = "Form1"
Me.Text = "Form1"

End Sub

#End Region

Declare Function GetTickCount Lib "kernel32.dll" () As Long
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Program to test relative speed of VB6 vs VB.NET
'Tests mathematical operations
'Coded 10.8.02

Dim x As Long
Dim z As Double
Dim start As Long

MessageBox.Show("Press OK to begin mathematical operations. Tests should take <1 minute.")

start = GetTickCount

'Basic operations, integer & floating point
For x = 0 To 10000000
z = 17 + 56 / (9 * 263) - 78 / (2.2 * 9)
Next

'Rnd
For x = 0 To 1000000

z = Rnd()

Next

'Trig functions
For x = 0 To 10000000

z = System.Math.Sin(23.5687)
z = System.Math.Cos(23.5687)
z = System.Math.Tan(23.5687)
z = System.Math.Atan(23.5687)

Next

'Sqr
For x = 0 To 10000000

z = System.Math.Sqrt(2315.126)

Next

'Exp & log
For x = 0 To 10000000

z = System.Math.Exp(22.561)
z = System.Math.Log(22.561)

Next x

MessageBox.Show((GetTickCount() - start) / 1000 & " seconds elapsed.")

End Sub
End Class
