Thanks John

I'm in a Win32 environment with IIS.

Here's what I'm trying to do:

1. I'm uploading a large file and I need a way of letting the user know that something is happening.

2. I'm using the javascript onSubmit event handler within the form to launch a web-page in another window. I don't think you can call a Perl script with this javascript event handler.

3. I want the web-page opened in the second window to run a Perl script which will try and find out the progress of the file upload and let the user know.

4. The above, of course, doesn't solve the problem of IIS timing out during a long file upload but that's another days work.

Thanks

2. I'm using the javascript onSubmit event handler within the form to launch a web-page in another window. I don't think you can call a Perl script with this javascript event handler.

Not that I like js solutions but you can open anyfile in a new window using any handlers, just do:

<form method="post" action="youscript.cgi" onSubmit="open('your_check_
+script.cgi')">
[download]

You can pass some extra parameters to the open function to define how you want it to appear (size scrollbars etc.)

Hope that helps.

Correction to my previous post to John

You can launch a Perl script from javascript

example:

<SCRIPT LANGUAGE="JavaScript">

function showProgress() {
var newWindow = open("http://localhost/cgi-bin/test.pl", "secondWindow
+", "scrollbars,resizable,width=250,height=150,left=720");
}
</script>
[download]

The form element would contain the following javascript event handler:

onSubmit="showProgress()
[download]

This depends on a few things... but, you could have a Perl script that watches the file upload by how much of the file is uploaded so far. You can steal the size of the file from the Content-size: header, pass it to the second script as a query string, and have the script return a page with a meta refresh tag so the page will reload every second or so.

That's putting more strain on the server; how important is it to have a window display the current upload?

Thanks John

I actually went down the route you suggested using a little more javascript then you mentioned. Again I ran into the problem that the upload file wasn't actully written out on the server until the entire file had been upload

Obviously the process is storing the chunks of uploaded data in a temp file or cache until everything has been uploaded so my second Perl script has nothing to report on until the file is finally uploaded which, of course, is too late

Just about to give up on this approach and simply have my second Perl script just display a file uploading message and exit when the file has been uploaded

Unless you can access the data as its being uploaded then this approach won't work. Still, I learned a lot of stuff trying it out

Thanks
