Maintaining Session

Guys, how to maintain a session ?

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

tcpClient.Connect("154.221.138.151", 6969)
End Sub

Public Sub send(ByVal data As String)
Dim networkStream As NetworkStream = tcpClient.GetStream()
'Dim networkStream As NetworkStream = tcpClient.GetStream()
If networkStream.CanWrite And networkStream.CanRead Then
' Do a simple write.
Dim sendBytes As [Byte]() = Encoding.ASCII.GetBytes(data)
networkStream.Write(sendBytes, 0, sendBytes.Length)
' Read the NetworkStream into a byte buffer.
Dim bytes(tcpClient.ReceiveBufferSize) As Byte
networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))
' Output the data received from the host to the console.
'Dim returndata As String = Encoding.ASCII.GetString(bytes)
'Console.WriteLine(("Host returned: " + returndata))
Dim f2 As New Form2
f2.ShowDialog()
Else
If Not networkStream.CanRead Then
Console.WriteLine("cannot not write data to this stream")
'tcpClient.Close()
Else
If Not networkStream.CanWrite Then
Console.WriteLine("cannot read data from this stream")
'tcpClient.Close()
End If
End If
End If
End Sub

All these at form1.

Form2 =

Public Class Form2
Inherits System.Windows.Forms.Form
Dim f1 As New Form1
#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.
Friend WithEvents TextBox1 As System.Windows.Forms.TextBox
Friend WithEvents Button1 As System.Windows.Forms.Button
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
Me.TextBox1 = New System.Windows.Forms.TextBox
Me.Button1 = New System.Windows.Forms.Button
Me.SuspendLayout()
'
'TextBox1
'
Me.TextBox1.Location = New System.Drawing.Point(40, 128)
Me.TextBox1.Name = "TextBox1"
Me.TextBox1.TabIndex = 0
Me.TextBox1.Text = "TextBox1"
'
'Button1
'
Me.Button1.Location = New System.Drawing.Point(176, 128)
Me.Button1.Name = "Button1"
Me.Button1.TabIndex = 1
Me.Button1.Text = "Button1"
'
'Form2
'
Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
Me.ClientSize = New System.Drawing.Size(292, 273)
Me.Controls.Add(Me.Button1)
Me.Controls.Add(Me.TextBox1)
Me.Name = "Form2"
Me.Text = "Form2"
Me.ResumeLayout(False)

End Sub

#End Region

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
f1.send(TextBox1.Text)
End Sub

Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
f1.tcpClient.Connect("152.226.138.151", 6969)
End Sub
End Class

How do I make it that, form1 connect then when I click a button to go to form2, form2 data can be captured too.
