Progress Indicator and transfer rates
Does FileUp's Progress Indicator have a built-in way to show transfer rates?

FileUp's Progress Indicator does not have any built-in way to show transfer rates for the current transfer. However, we have come up with a modification to the Progress Indicator sample that estimates the current rate of transfer and average rate of transfer (in bytes per second).

The code below is a replacement for the progress.asp file that comes with the Progress Indicator ASP QueryString sample. The Progress Indicator sample is installed with FileUp and can be found on your local machine here at: http://localhost/SAFileUpSamples/br> (This modified progress.asp file can also be downloaded from the Attachments section below.)

In addition to using the code above for the Progress Indicator page, you may need to increase the height of the window the Progress Indicator is loaded in. You can do this by modifying the JavaScript that opens this window from the page that initiates the file transfer. In our Progress Indicator Sample that comes with FileUp, this page is form.asp. An example of this code is:
