If the javascript code is not run on the client side then whatever you post will not work. Sorry, but I do not know of a way around this, I've tried similar things in the past and had no luck. For forms that do not include javascript WWW::Mechanize works nicely. If you have any other specific perl issues post them here. Or maybe someone knows a way around this javascript issue and we'll both learn something. You're tackling a lot of different things at one time: c++, perl, sql, CGI and xs - you may want to consider narrowing your focus a bit. As far as the c++ issues go, I would suggest that you first have the perl code write the data to disk, then have the c++ code read it off the disk, or just do whatever you intend to do with the data all in perl. Calling perl from c++ is a large can of worms. Unless you have a compelling reason for doing this, I would advise against it. It might be easier to put your c++ code in a library and then create a wrapper around that with xs. One approach that generally works for me is to identify stand alone tasks, get them working by themselves, then work on making them play together. Mike
