As far as I know you cannot add a progress bar because the upload is being done in a single statement and there is no way to determine how much of the file has been uploaded at any given time. However, if you broke the upload into chunks and wrote the chunks in a loop you could update a progress bar. In one-byte chunks it would be

for each b as byte in file
    write the next byte
    update the progress bar
next

close the stream
