Subject Re: [FileUpload] how to disable default output to server file system?
Date Wed, 07 Jun 2006 19:06:06 GMT

That did solve my problem.

A question: If the threshold is small and the uploaded file is big, it will
be saved automatically. is there any method to get the file name on server?
I could not find it.

Regards,
Xiaobo
