File upload

[mioriticus]

Hi all,

I'm looking for a way of finding the size of a file before actually
uploading it.
I know I can check the size of the file on the server after the upload and
if it's too large acording to my criteria abort the rest of the operation,
but it would be nice to be able to make the check before wasting time and
bandwidth.

Thank you in advance,
Bogdan Ionita [NEKO]

There is no cross browser way to do it, unless you write a Java Applet that
circumvents the "sandbox" (which may raise some eyebrows). Remember that
Java, and in fact ActiveX, was designed so that it cannot do bad things to
the users computer. Thus, some of the functions traditional programmers
take for granted, such as getting file sizes, are now much more difficult,
if not impossible.

Within IE though, assuming you are designing for a very specific audience,
you can use VBScript to do it by creating a FileSystemObject.

Look online for Referneces for how to use the FileSystemObject. This object
will allow you to run rampant on the user's hard drive, such as delete files,
copy, read file names and sizes.
