File Streaming Over HTTP
I'm having a trouble with HTTP file transfer. I use an ASP file to provide controlled access to some files and stream them back to the client by adding the "content-disposition: attachment" header.
This usually works perfectly, but I've noticed that if I try to stream a ..RAR file, the client browser does not show any "open/save" window (it simply ignores the file transfer), and .RAR appears to be the only file type which causes it to behave this way. Can anyone explain me what this means or what it may be due to?
I use MS IE 6 and IIS 6... and the transfers are all HTTP/1.1 of course.

I have an exe file on a server that reads an XML file ( as a parameter) and generates a new file for downloading. However, most servers won't allow an exe file to create the new binary file. Is there any way that I can execute the exe file and have it download straight to the client instead of saving to the server?

Do anyone has got any idea about how to deal in ASP page when any link in asp page contains other URL that does not exist or open.
Basically I want to trap this kind of error when user is redirected to other site in a new window and it can't display that page may be due to non existent of that URL or page removed.

I am encountering an error HTTP 404 - File not found. It seems that
when I upload a file with a symbol # in the filename, this error
occurs (e.g. case#2.pdf). I cannot access the file I uploaded. But
when I upload the same file with a different filename or just without
the symbol # (e.g. case2.pdf) , it works I can access the file. Why is
this the case?

I'm developing an Asp.NET system to take a CSV file uploaded via the web, parse it, and insert the values into an SQL database. My sticking point comes when I try to split() the string returned by readline() on the file.
The following code snippet works for me:
tokens = "one,two,three,four".Split(",")
for each token in tokens
response.write("<td>"+token+"</td>")
next
However, if I take the next line in the CSV, read using StreamReader.ReadLine on the PostedFile.InputStream, I receive "Object reference not set to an instance of an object." which I have narrowed down to be my string holding the line. Further investigation reveals that no other string member functions work on my line (.ToCharArray, .ToString, etc).
I suspect that StreamReader.ReadLine is not correctly returning a string, even though Response.Write(line) displays what I would expect .....

Here is a written descripton of my webpage.
One frame split down the middle. The left side is the menu and the right
displays what is selected from the menu.
the user selects from the menu and on the right, clicks on "download image"
link. the user is presented with a download dialog box. The user saves the
image and when it is completed goes and selects another item from the menu.
But this time nothing happens.
It is like i have to refresh the page before anything works again. It is
like it is stuck on the ASP binary stream file that forced the download.
on my link i have
<a href="donwload.asp" target="right">download image</a>
How can i fix this?

I have a page which allows the user to open one of several spreadsheets by
streaming the XLS to the client.
On my development site, everything appears to work fine. On the live site,
it works fine for the vast majority of users, but not for my colleague & I.
When this page is called with the correct inputs, the standard
Open/Save/Cancel/More Info dialog should appear. In the dialog, it gives the
following details:
Filename: Gothenburg Sweden.xls
File type: Microsoft Excel Spreadsheet
From: Servername
Clicking on open, means that the file will be opened in the local copy of
Excel; this works for most people, except one colleague and myself. In our
case, after clicking on Open, we get the following error msg:
"Internet Explorer cannot open travel.asp?journey=1 from <servername>
Internet Explorer was not able to open this internet site. The requested
site is either unavailable or cannot be found. Please try again later."
Anybody got any ideas about this? Code:

I've got a particular project to do and because of my very basic understanding I'd appreciate being pointed towards a relevant example. Basically I want to have my client side stream the contents of an XML using SOAP to a webserver.
I don't want to attach an XML file, rather just stream the contents. I have to write both parts. There must be good tutorial around somewhere.

I'm about to venture onto a new project of developing an ASP Page that captures images from a streaming web camera, and displays them (refreshs) the image every 15 seconds.
The question I have, is it possible to capture images (every 15 secs- from the webcam on the intranet) and store that snap shot as say a .jpg file in a folder, and then have the ability to continuously add images to this folder, so at a later date you could develop a system that would display photo after photo simultaneously, fast motion of the project in action.

We are using ASP pages and the response object in conjunction with the
binarywrite method and a custom com dll in order to stream files back to
users. All works fine, except mhtml web archives(*.mht or *.mhtml files) .
When we stream an mhtml web archive back to the user we see the actual file
inside the browser window and not the web archive document the way it should
be displayed.
We are setting the content type property to message/rfc822
for mhtml files. We also set the content-disposition header ( like this
content-disposition: filename="mytest.mht" ) This file opens up fine if we
place a direct link to the file, however exposing a directory of files is
not an option available to us.
We have also created a cgi in c that does
the same thing as the ASP however to no avail we still get the actual
contents of the file and not the mhtml document. This happens on both IIS 5
and 6. Any suggestions???

I am working on an app that needs to stream binary files(such as PDF or WORD docs) to the browser. I cannot just pass a URL pointing to the file directly. I've tried the following in an ASP file:
Code:
Response.ContentType = "application/doc"
Response.BinaryWrite strData
where strData contains the binary data content of the WORD file in a string variable (for PDF, I would set the content type to "application/pdf").
However, the browser displays the data itself, rather than hosting the doc in the appropriate browser applet.

I am working in an intranet/extranet application in which the user should be able to see some documents (specially doc and pdf). These documents will be stored in a safe place in the server preventing anybody from downloading them directly from the URL.
In order to achieve this, I have made an activeX component which takes the original file and stream it to the client. I have basically two questions/problems.
First, is there a way to manipulate the document generated dinamically in order to change the way it is displayed in the browser(zoom factor,etc)? By default it depends on the client configuration. Maybe I could use an application.word object in the ASP but the problem is that I don't have the document in a file, I only have a stream sent from the server.
Another question is, how can I avoid the download dialog(open/download file prompt) on the client? I always want the document to be displayed on the browser. I know this is for security reasons, but can this be configured in some way through the IIS options for the web site? Code:

I have created a Spreadsheet object that I need to stream directly to a file through the browser. I can not save this file, that I would then stream, to the web server, even though this would save me a lot of aggravation.
Since Microsoft seems to see no value in providing any documentation for their OWC 11 components, I am just one of many developers groping around trying to find how to use this.
