not strictly an asp.net or C# question but?.....

[Ollie]

The client I am currently working is using a thrid party framework to
generate web content, this framework utilizes asp.net web services I have
written for them, one of these web services streams the contents of file for
download by the end user.

My question is how do I write the following bit of code as pure HTML so that
the web service can return the complete HTML script required to download the
file so that the third party then can display the HTML a they require, hope
this makes sense...

The code lets the user download a txt file when the asp.net page is loaded
or a button is click, but what is the HTML output for this?

FileStream fileStream = new FileStream("C:\\XXXXX\\Test.txt", FileMode.Open,
FileAccess.Read);
long fileSize;
fileSize = fileStream.Length;
byte[] buffer = new byte[(int)fileSize];
fileStream.Read(buffer, 0, (int)fileSize);
fileStream.Close();
Response.ContentType = "application/txt";
Response.AddHeader( "content-disposition", "attachment;
filename=RJL00102.x01");
Response.BinaryWrite(buffer);

Cheers in advance

One note: I'm not sure fileStream.Read(buffer, 0, (int)fileSize);
is guaranteed to read exactly fileSize bytes.

Your should just output the contents of the file (along with an http-header),
it shouldn't add extra html (you did remove everything except directives
from the aspx file?).

If the file really exists on disk, you could also look at the
HttpResponse.WriteFile method.
