direct export of a crystal report

[Fh]

Hello,
I'm using the following code to send the content of a report directly in a
aspx page.

this code is working fine,
but the pb is that it doesn't fill the page with the document.
it displays automatically the 'open or save' popup...
I wish to open it directly in the IE window without asking anything?
how can I do so?

Thanks for your help

Response.BinaryWrite(m_stream.ToArray());
Response.End();
