checking for local files

[kbrown2974]

Writing a script that looks for a PDF file on the local system. If the file is found, then it is brought up in a new window. The user enters a file name in field and we look it up that way. Is there a command that will search for a file?

No sorry, no webbased programming language at all has permissions to search someones local directory.

I'm confused then. We can pull up a pdf exists on the network. We can't check to see if it does not exist?

I feel quite certain that ActiveX could do so. ActiveX, however, only runs in IE (which means I don't have to worry about it. :p) and by default is set to disable for everything except signed scripts, which is set to prompt.

Here is the little bit of code. pdf is document.form.reference.value. No ifexist or anything like that??

if (pdf != "")
{
pdfname = "i:/apps/grid/" + pdf + ".pdf";
winname = pdf + "win";
pdfwin = window.open(pdfname,winname);
pdfwin.focus();
}

Sorry, my bad, i thought you meant local, as in the visitors actual computer not the website server.


JS wont do it.

PHP will.

AH u did, ummmm

Well as far as I thought, JavaScript couldn't get within a visitors computer at all.

Ummmm...

Let me do some research.

You can get around some of the restrictions by changing the file type to HTA (hypertext application) instead of HTML.
