ต้องการสร้าง class มารับค่าจาก form1 ไป show form 2 ครับ

Dim sb As String
        sb = "SELECT file_no from tb_use where user_dept = '" & departmentIDA & "' ;"
        Dim sql As String = sb.ToString()
        Dim com As New OleDbCommand()
        Dim dr As OleDbDataReader

        With com
            .CommandType = CommandType.Text
            .CommandText = sql
            .Connection = Conn
            dr = .ExecuteReader()
        End With
        If dr.HasRows Then
            dt = New DataTable()
            dt.Load(dr)
        Else
            dt = New DataTable()
        End If

        'departmentIDA = showdata.department
        Conn.Close()
        If txtuser.Text = UserIDA And txtpassword.Text = PassIDA Then
            Form2.Show()
            txtuser.Text = ""
            txtpassword.Text = ""
            Me.Hide()
        Else
            MessageBox.Show("กรุณาใส่ข้อมูลให้ถูกต้อง", Me.Text, MessageBoxButtons.OK, MessageBoxIcon.Warning)
        End If

Public Class Form2

    Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
        Login.dt = DataGridView1.DataSource
    End Sub
End Class
