I have used this code for the past 3-4 years and never had any problem with any version of .NET or Adobe Reader.  It is supposed to open a PDF in a new browser window.

I copied this code to a new page in the same web application and it does not work.  To describe how it does not work; the resulting ASPX is just blank.  No PDF.  No Adobe toolbar.  Nothing.

I've tried all sorts of variations on the code but no luck.  I tried adding a Response.End to the end of the code, but this threw an error. ???

It still works fine in the original page though.  Very wierd.

Can anyone provide some insight here? 

ASPX code:  Just the @Page directive, nothing else

VB Code: (Page_Load event)

If IO.File.Exists(strReport) = False Then
Response.Write("Cannot find file " & strReport)
MyFileStream = New FileStream(strReport, FileMode.Open, FileAccess.Read)
   FileSize = MyFileStream.Length
   Dim  Buffer() As Byte
   ReDim Preserve Buffer(CInt(FileSize - 1))
   MyFileStream.Read(Buffer, 0, CInt(FileSize - 1))
   Response.BufferOutput =
   Response.AddHeader("Content-Length", Buffer.Length.ToString)
   Response.AddHeader("content-disposition", "inline;filename=YourReport.pdf")
   Response.ContentType = "application/pdf"

End If
