How do you do that? When using CGI, I don't really have much influence on what's put into the header. > After 0 seconds it will start the file download.

The file is ready some time after the header has been printed: When the uploaded file has 20000 rows, it currently takes about 45 minutes to process. Most files are below 300 rows, though, and take about a minute. The information on the web page that has been printed during creating the file must not go away. The file may be created or not, so I'd have to put it into the header after the page has been rendered by the web browser. That probably won't work. So I just need to be able to print, or do, something that makes the web browser open it's downloading dialog box right when the processing has finished and the file is ready for download. Maybe that isn't possible? Currently, the files are being sent by email. That leads to a workflow which really sucks. Displaying them in a table on the web page may help a lot, but that would be a lot of work because different columns need different alignments, colour is used for some fields, and it is unknown how many columns there are before the file is finished. The files are created as xlsx spreadsheets, and the user needs to look at them to check the result. Is there a function which can display xlsx as a table on the web page, with correct colours and alignments? That's something I really don't want to program. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
