PDF Open new window?

I finally got my application to work where on a blank page a pdf will open (the pdf is being brought out of a database as a ole object).  The only problem I have having now is the fact that it opens in a acrobat window and leaves the ie window blank, so you have two windows open.  How can I make it open within IE??

Here is my code.

If rd.Read() Then

                    Dim filename As String
                    Dim filesize As Integer
                    Dim contenttype As String

                    filename = rd.GetString(0)
                    filesize = rd.GetInt32(1)
                    contenttype = rd.GetString(2)

                    Dim filedata(filesize) As Byte

                    rd.GetBytes(3, 0, filedata, 0, filesize)

                    Response.Clear()
                    If (forceDownload) Then
                        Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename)
                    Else
                        Response.AppendHeader("Content-Disposition", "inline; filename=" + filename)
                    End If
                    Response.ContentType = contenttype
                    Response.OutputStream.Write(filedata, 0, filedata.Length)
                End If

                rd.Close()
                con.Close()
