check file size before post

[nicholas]

when I upload a file, I can set in my code not to save it if the file size
is too large.
But then the user has allready been waiting a few minutes to upload his
file, as this can only be controlled once it is uploaded.

I would like to say to the user the file is too large before it uploads it.

any ideas?
thx

You can't access the filesysytem on the client unless you want to use java
applets or ActiveX controls.

hi

you can get your page size
int fileSize = Page.Request.Files[0].ContentLength;
so if your page content is bigger that a value put a message not to upload
the file.

this will not work, as the file is already uploaded by this time.

as noted, the only option is an active/x control (java applet will not
work).

yes, your are right. only with activex can find on client machine the file
length.

this will not work, as the file is already uploaded by this time.

Nicholas,

The machine.config file defines the <httpRuntime> element that can be
used to control the max file size. For example,

<!-- set max size to 60 megs and max timeout to 60 minutes -->
<httpRuntime executionTimeout="3600" maxRequestLength="61440" />

You can override this in your own application's web.config file so
that it only affects your application and not all applications.

If a user attempts to upload a file greator than the max size, the
browser will immediately give the user an error message.
Unfortunately the error message is not user friendly. If you can live
with that, that is the easiest thing to do.
