Rename a file using the upload tool Uploadify
Hi Experts,
I've found this wonderful code that does the job for me. It is the classic ASP version of Uploadify.
Now I'd like to add simple rename action for each file that gets uploaded. In my default page I've set a variable caseID and for testing purposes I've given it the value "10"
Now I'd like to change the uploaded file name so it starts with this number and a underscore. So if my file is called "test.jpg" it should be renamed to "10_test.jpg"
Could this be done somewhere in the code of this page (see code)?

Hi Big Monty,
Thank you for your quick response. Looking at your response I conclude that I had to ask where in the code should I put this rename action?
Could you please tell me where this action should be put within the ASP files?
Kind regards,

Thanks again for your quick response. And yes this works but how do I parse the caseID variable to this file?
you could change the Save function in the class to accept it as a parameter
