Re: Checking file size before upload.
I dont think it is possible with javascript. In order for this to be true,
either the script would need access to the local filesystem, which it does
not...or the browser would store the filesize of the selected file somewhere
accessible in the dom. That would be a very cool thing for the browser's to
do, but I have never heard of this, so I very much doubt that is true
either.
If all of your users are on IE and they trust you and are willing to click
yes on the security warning (or you can sign the script) , you can get
access to the fileSystemObject and do some scripting to get the filesize of
the file they selected.
Useing the fso like this is usually not acceptable, but here is the code if
you want to see what it will do first hand.
Stick this in your head.
SCRIPT LANGUAGE=JavaScript TYPE=text/javascript
!--
function fsoGetFile(fname) {
fso = new ActiveXObject(Scripting.FileSystemObject);
a = fso.GetFile(fname);
alert(a.name + ' is ' + a.size + ' bytes');
return;
}
//--
/SCRIPT
and in the body...
form name=upload
input type=file onChange=fsoGetFile(this.value);
/form
If you are willing to spend $200 I reccomend JUpload.
http://www.aspupload.com/jupload.html
On a side note, this is one thing that I have always thought would be very
cool for an applet like JUpload to be included with ColdFusion as uploading
files is always one of the biggest problems developers have.

Re: Checking file size before upload.
Wow, after staring at the code scratching my head for a few minutes I
finally think I get the concept of what you are doing.
Basically this is taking the filename and loading the image via a file://url
from the local filesystem into a frame and getting all of the relevant data
and passing it back to the original page with javascript. This is a really
cool idea.
Without testing the code out, is this not a huge security problem? I'm
thinking that as long as the browser is can handle the mime type that it
would be possible to grab almost any file from the users hd using the same
concept with a few modifications.

This is a really cool idea. Exactely, the idea is not mine, I've got it from a script somewhere, it was crude and simple but cool, so I expanded it much more and adapted the whole beast to make a DW extension out of it. Just a note, I am not using a frame, just creating a new image object passing an url to the new Image constructor. The funny thing is that the url using file:// as pseudoprotocol, so I am pointing to the local file system, that's the core idea, but, again, it's not mine. Without testing the code out, is this not a huge security problem? I'm thinking that as long as the browser is can handle the mime type that it would be possible to grab almost any file from the users hd using the same concept with a few modifications. Well, it may be, but there aren't too many info you can grab from a file this way. For images you can take dimensions and file size... I have no idea if you could grab dangerous info pointing to a text file. Anyway, you still can't upload an arbitrary file from the local file system, but maybe you can raed some info... Since we are posting already huge chuncks of code (I hope people don't mind too much). I developed quite a decent CFML file upload code in the past months. A few details were adapted to make it works better in Ultradev, but I think it may be handy. Using it together with the JavaScript code I posted before you have quite a sophisticated solution. I hope one of these days I will write an article out of it, or maybe a custom tag, in the meantime here it is: !--- If a form containing a field called photo was submitted --- cfif isDefined(form.photo) AND form.file NEQ !--- Check to see if the browser reported a well formed content_length HTTP header --- cfif cgi.content_length EQ cfscript WriteOutPut(Your browser reported a bad formed HTTP header, this could be caused by an error, a bug in your browser or the settings on your Proxy/Firewall); /cfscript !--- Abort processing --- cfabort /cfif !--- Set max size allowed in KB--- cfset tmtMaxSizeKB=10 !--- Convert the value in byte --- cfset tmtMaxSize=#Evaluate(tmtMaxSizeKB*1024)# !--- Check for file size as reported by the HTTP header--- cfif Val(cgi.content_length) GT tmtMaxSize !--- Use cfscript to write an error, to avoid UD display bad things if the code is written above the body tag --- cfscript WriteOutPut(The selected file's size is greater than the #tmtMaxSizeKB# KiloBytes maximum size allowed, please select another one and try again.); /cfscript !--- Abort processing --- cfabort /cfif !--- Upload the file, make unique names on clashes and allow only images --- cftry cffile action=upload filefield=photo destination=#ExpandPath(images)# nameconflict=makeunique accept=image/* !--- If the file upload failed --- cfcatch type=Any !--- Display errors --- cfscript WriteOutPut(An error occurred during the file upload process.brbr); WriteOutPut(This is likely due to one of the reasons below:brbr); WriteOutPut(1) The MIME type of the uploaded file was not accepted by the server.

Matt Robertson [EMAIL PROTECTED] wrote in message Well, is this thing just too cool or what? Works like a charm. Thanks, Massimo! Any compatibility issues with regard to browsers and the js used? No NN 4 and no Mac browsers, but it fails silentely on both cases. The reason why it fails on the Mac is that on the file field on Mac OS you will see just the name of the file, not the full path.
