Progress bar on upload with Inet control?

Hi!

I seem to have hit a brick wall here.

I have an activex control that uploads a large (5 Meg) file to a server via http (ftp is not available on the server). I'm using the Inet activex control to execute a post of the binary data.

It worked great when I was testing with small files. When I tried it with the actual data file I noticed that from the time that I clicked on the 'Upload' button to the time it finished - no user feedback was happening.

I want to add a progress bar to the control to let the user know what percentage of the post is complete. There's a ton of tutorials on how to add a progress bar, but I was unsuccessful at finding a tutorial on how to calculate the size of the data transfered. I don't even know if this is possible with the Inet control. (reading the reponse data is not a problem - I need to read the size of the data that has been sent and compare it with the size of the data initially to set the progress bar)

Any suggestions?

Thanks much!
