Response.OutputStream

Hi there

I want to stream my word document on the http response outputstream, but I get an exception:

NotSupportedException: Specified method is not supported.]
System.Web.HttpResponseStream.set_Position(Int64 value) +28
?.?.?(Stream ?) +300
?.?.?(Document ?, Stream ?, String ?) +50
Aspose.Words.Document.Save(Stream stream, SaveFormat fileFormat) +61

Some of the code I am using:

Response.Buffer = true;
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentEncoding = Encoding.GetEncoding("ISO-8859-1");
Response.ContentType = "application/msword";

Response.AddHeader("Content-Disposition", "attachment;filename=xxx.doc");

Document doc = new Document("adoc.doc");

// add stuff to document...

doc.Save(Response.OutputStream, SaveFormat.FormatDocument);

What could I be doing wrong?

Thanks,

Peter

I have found out that there is another method

doc.save(string filename, SaveFormat fileformat, SaveType savetype, HttpResponse response)

and this might be fine, except I have a general "service" which wants to stream on any supplied output stream - it is independent of Http, and doesn't even know it runs in a web context, just that it shoud generate a document and stream it.

How can I achieve this? For example, with Aspose.Pdf I can stream on HttpResponse output stream like this:

Pdf pdf = new Pdf();
pdf.BindFO(xmlDoc, xsltPath);
pdf.Save(outStream);

Where outStream could be Response.OutputStream.

Thanks,

Peter

To workaround you can save to MemoryStream first using Document.Save method and then copy the contents of the MemoryStream to HTTP response.
