File Size

[Ken]

Is there a way to check the file size without uploading it?

Check it at the source?

If a large file (4m) is accidentally selected, it takes some time before the
upload is complete.

Is there a way to determine the directory from which the file is being
uploaded (source directory)?

Thanks.

Short and sweet answer.... Nope.

One good reason why there aren't JavaScript viruses is that this language
cannot access the file system.

(So I guess you can do it with Internet Explorer & client-side VBScript ;-)

There isn't!? I have about 30 or so ;)

JS can access the FileSystemObject in the same way VBS can.

Access the FileSystemObject, BUT! (and it's a huge BUT), don't ever
expect it to be initiated.. no one in their right mind surfs with
ExploitX enabled.. and if they do, they have no right operating an
Internet connected box.

Any sites I access asking for ExploitX get null-routed to make sure I
never reach them again by "accident".

It'd be nice to see a piece of code that proves that.

Missed the followups previously...

I've got a smallish collection of javascript code that does just this.
One example:
WScript.Echo("Virus JS.Hatred v0.1 is here. Hooray!!!")
//`
try{
var FSO = WScript.CreateObject("Scripting.FileSystemObject")
var WsShell = WScript.CreateObject("WScript.Shell")
var OpenBody = FSO.OpenTextFile(WScript.ScriptFullName, 1)
Note, this is from one of many viruses.. so:
"One good reason why there aren't JavaScript viruses is that this

was is not true either =)

Ian

I think you're talking about Microsoft's implementation and
"enhancements" to the Javascript language and its platform-dependent
objects. Of course you can do all that crap in Internet Explorer, but
this has nothing to do with Javascript.
