Hi,

I am executing the following method which save a copy of a page to the web server that can then be emailed to a user:
Code: 
  ' This method saves a copy of this page to a particular location on the web server.  This copy 
    ' is then accessed by when the email is generated and sent to the administrator of the system.
    Private Sub saveReceipt()

        Dim csReg As New clsReg
        Dim outputFileName As String = dstDataset.Tables("Organization").Rows(0).Item(0).ToString() + ".Html"
        Dim outputFileLocation As String = csReg.readReg("Software", "SureTxt", "ReceiptPath")
        Dim renderedOutput As StringBuilder
        Dim writer As StringWriter
        Dim htmlWriter As HtmlTextWriter
        Dim outputStream As FileStream
        Dim writerStream As StreamWriter
        Dim filename As String
        Dim nextPage As String

        Try
            ' create a HtmlTextWriter to use for rendering the page
            renderedOutput = New StringBuilder
            writer = New StringWriter(renderedOutput)
            htmlWriter = New HtmlTextWriter(writer)
            ' render the page output
            Page.RenderControl(htmlWriter)
            ' save the rendered output to a file
            filename = outputFileLocation & outputFileName
            outputStream = New FileStream(filename, FileMode.Create)
            writerStream = New StreamWriter(outputStream)
            writerStream.Write(renderedOutput.ToString())
            writerStream.Flush()
        Catch ex As Exception
            Throw ex
        Finally
            'clean up
            If (Not IsNothing(outputStream)) Then
                outputStream.Close()
            End If
            If (Not IsNothing(htmlWriter)) Then
                htmlWriter.Close()
            End If
            If (Not IsNothing(writer)) Then
                writer.Close()
            End If
        End Try
        ' Redirect the user to the welcome page.
        Response.Redirect("Welcome.aspx")
    End Sub

A problem occures when I exit the method and return the to the method that called it. The exception that I am gettings is a ThreadAbortException. Any suggestions on what can cause this or how to prevent it occuring.
