Hi, everybody.

I'm using database to store attachment for Load Balance considering, and I download my attachment using the following statment

                Dim Buffer As Byte() = CType(dr("Content"), Byte())
                Response.ContentType = CStr(dr("FileType"))
                Response.AddHeader("Content-Disposition", "attachment;filename=" & dr("FileName"))
                Response.BinaryWrite(Buffer)
                Response.Flush()
                Response.End()

It provide client user a dialog to Open or Save, I notice that when I click "Save" it works fine, but I click "Open" it cannot work(the application like notepad opens and cannot find the file)

But when I logout the DotNetNuke, the Open works well. It only don't work on Log in mode.

What's the problem, can anyon help? thanks a lot.

I use the code below in numerous apps and it works fine. Of course it's in C#, so you'l have to "re-write" it. "file_" is a class that I use to populate document info from DB. DocumentData is a byte[] - so it's the same as your Buffer assignment. Perhaps, the only notable difference is the Content-Length header assignment. And absense of Flush() call.

Response.Clear();
Response.ClearHeaders();

Response.AddHeader("Content-Disposition", "attachment; filename=\"" + file_.DocumentName + "\"");
Response.AddHeader("Content-Length", file_.DocumentData.Length.ToString());

Response.ContentType = file_.MIMEType;
Response.BinaryWrite(file_.DocumentData);
Response.End();
