Saving info from server file to local file

Hi

I wonder if someone could please give me some suggestions about the following problem i have:

I have a web application that uses VB6 COM-compoents for handling the business logic. I want from the web page give the user the possibility to save some page variables to a text file located on his local machine. I also want to give him the possibility to choose where on the local computer the file will be created (with some sort of file save dialog).

Can someone help me with this I would be very greatful

regards
Helmut
