VS 2012 - Class Needs To Access Application Space In Parent

I've got a class that create a report in a PDF - looks like this

Code:
Option Explicit On
Imports PdfSharp
Imports PdfSharp.Drawing
Imports PdfSharp.Pdf
Imports System.Data.SqlClient
Public Class acsReportWriter

[Code] ...

And I access this class from within a web service call like this

Code:
Using acsRpt As New ACSReport.acsReportWriter
acsRpt.StartDocument(strViewName, strTitle, username)
Using dcn As New SqlConnection(connStr)
Using cmd As New SqlCommand
cmd.CommandType = CommandType.StoredProcedure

[Code] ....

So - in that web service I can access APPLICATION like this

Code:
With Application
.Lock()
' need to do work here
.UnLock()
End With

I need to be able to access APPLICATION from the acsReportWriter class to put status message every so often so another AJAX POST can fid out how many pages are done.

I'm having a hard time even adding IMPORTS to SYSTEM.WEB in the acsReportWriter class
