Hi Alessandro,
Thank you for your help. But I am a newbie in aspnet and C#. Pardon me, if I sound silly.
First of all, my development environment is asp.net for web. The codes you provide me with seems to be meant for window base (I really don't know how to apply it). Therefore, I didn't manage to get it working. I am using "file field" with the default "browse" button.
Regards,
Je
