open binary stream of PDF in browser and NOT popup the Download dialog box

Question

Hi, I have an aspx page that streams binary data to the browser using the Response object, in the form of PDF by setting Response.ContentType = "application/pdf"; Instead of opening acrobat reader in the browser itself, it pops up a dialog box prompting the user to open/save/cancel the .aspx file. I did some research o it and found that the Acrobat Reader's setting must be changed to allow it to display in the browser and not try to download the file. the setting is edit - preferences - options - Display PDF in browser. I have checked this option and it still doesn't display in the browser window. [If the response is a word doc, i.e., Response.ContentType = "application/msword"; everything works fine. The word document is nicely displayed inside the browser window.] I'm wondering if there is anything that should be programmatically set to make the PDF open in browser and NOT popup the download dialog box. I would really appreciate if anyone can point me in the right direction. fragment of my code that streams the binary data....... ------------------------------------------------------------------ MemoryStream PageData = new MemoryStream(); byte[] PageBytes = null; do { PageBytes = obPageStream.Read(32768) as byte[]; PageData.Write(PageBytes, 0, PageBytes.Length); } while (PageBytes.Length > 0); PageData.WriteTo(Response.OutputStream); Response.Flush(); Response.Close(); -------------------------------------------------------------------- Thanks, Srivalli.
