I'm hoping someone can help with this problem; I've seen only a handful of
postings related to it, but with no clear resolution.
I have an ASP.NET 1.1 page that downloads requested files via the
"Response.Binar yWrite(...)" method. The problem is that the page is
dynamically built, and after the download completes all javascript functions
suddenly break or exhibit unpredictable behavior.
I've traced the issue down the use of the "attachment " attribute when
setting the Content-Disposition header. For example:
Reponse.AppendH eader("content-disposition", "attachment ;
filename=testfi le.txt");
.... will download the file intact, but the page will lose all of its
javascript references.
I'm also adding the obligatory "Response.End() " statement after the last
"Response.Flush ()".
One odd note is that omitting the "attachment " attribute altogether will
allow for some files to download and NOT break the page afterwards. However,
this is not reliable for types that could be rendered to the browser (.txt,
etc.).
Has anyone else come across this problem, and is there any consensus on what
might be causing it? Any feedback, resources, etc., here would be greatly
appreciated.

Hmmm, are you saying you want to have some Javascript in the browser, in
the same page/frame that is writing the file out? That can't happen,
you can't mix MIME types; either you are writing HTML to the browser, or
sending the attachment in 1 response...Are you using frames, or what is
the page layout here?

Ok im trying to figure out how internet explorers file download box always
seem to at least come close to knowing the exact file size/time to download.
From what I can tell its getting its not getting its info from the
content-length. I know this because I can test query against a apache box
that does not return the content length however IE still knows the size of
the files.
What am i missing?

Hi
I used the code below to automatically open a pdf file when the user clicks
on a menu option.
It works great on local machine, but when I
uploaded it to hosting site and then tried it,
I get a 'File download-security warning' window popping up that ask if I
want to download or open the file.
It wants to download the aspx page itself , instead of the pdf file.
I'd would like it to offer to open the pdf file, or avoid this security

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
