[dba-VB] Launch and monitor external programs from .NET (was: Open PDF file)

There are no stupid questions - just stupid answers :-)

Yes the user (who was me) does have adobe reader installed.

Part of my program uses the following code to show pdf's that are 
created from DataDynamic's Active Reports (this was code provided by 
DataDynamics):

         Dim m_stream As New System.IO.MemoryStream()
         Dim rptCombined As New DataDynamics.ActiveReports.ActiveReport3

         ' Other code which creates the rptCombined report

             If Me.PdfExport1 Is Nothing Then
                 Me.PdfExport1 = New 
DataDynamics.ActiveReports.Export.Pdf.PdfExport
             End If
             Me.PdfExport1.Export(rptCombined.Document, m_stream)
             m_stream.Position = 0
             Response.ContentType = "application/pdf"
             Response.AddHeader("content-disposition", "attachment; 
filename=PVPReports.pdf")
             Response.BinaryWrite(m_stream.ToArray())
             Response.End()

It looks like some of this might be able to be used to show the pdf 
files.  What happens is that the user has the option to save or open 
the file.  This is what I want for the pdf's as well.
