Hi, I have a page that dynamically generates a PDF file using ActiveReports. The code that does it looks like this. m_stream.Position = 0; //this is memory stream Response.ContentType = "application/pdf"; Response.BinaryWrite(m_stream.ToArray()); Response.End(); Of course this is only a part of the code, but the point is, I am using the Response object to make this happen. This works beautifully with the desktop browser. The Acrobat reader launches, and I see the PDF file inside the browser. But not so with Win Mobile 6.0 IE. * The PDFViewer does not launch * It asks me if I want to save * So I say yes. It saves with the .ASPX extension! * And it does not let me change the extension. I am stuck with the ASPX extension, and there is no tool in WinMobile 6.0 that I know of that would allow me to do that. Thanks in advance.
