Hello, I would like to know how to implement a file upload progress status on a PHP and an ASP.NET web site to indicate that the page is communicating with the server. This will give user an indication that the file upload is in progress and not to click away from the page because they may think the loading is too slow. I have found some JavaScript progress bar examples, but it is independent to the time the page will render and may produce false indication. If anyone knows of an excellent example I can easily implement onto my web site, please share. Many thanks, RCorr |

you don't indicate if you need it for an asp.net or for a php page. PHP will give better results than javascript but will still be a bit off as it can't really touch the post data streaming in. The RAW_POST_DATA variable is only populated if it doesn't recognize the mime type but you need a valid mime type for file transfers to work. PHP will loose more accuracy on large files than on smaller ones. Here's an article on an .NET control that will do what you need: http://mattberseth.com/blog/2008/07/aspnet_file_upload_with_realti.html" rel="nofollow - http://mattberseth.com/blog/2008/07/aspnet_file_upload_with_realti.html Perl would be another option which can touch the data stream. -------------
