Request.BinaryRead()!
 
Under what circumstances can Request.BinaryRead() be useful & when
should it be used?

Assume that the value of Request.Form("anyvalue") is "a" (without the
quotes). The output of

<%
Response.Write(Request.BinaryRead(10))
%>

is "??a" (again, without the quotes). How does ASP compute this value?

Thanks,

Arpan

Most commonly used for uploading files to the web server, as
submitted by the <input type='file'> HTML form field.

Without the use of a third-party component, you cannot mix using
BinaryRead with using "ordinary" form fields; the use of one
precludes the use of the other. Because of this, most components
supply a surrogate Form collection.

Unless, of course, you unpick the uploaded content and pull out in
the individual form fields as well as the binary stuff.
Fiddly, but possible.

HTH,

And there are some non-component ASP classes that use
Request.BinaryRead() for file uploading and still allow access to
regular form fields with a special syntax such as:
