Re: Can't use TComponent in thread object?

It might have to do with the sharing flags you specified when opening the file.

But as I said before, you shouldn't need to poll the size of the file. As you download the file, simply keep track of how many bytes you've downloaded. That will also be the size of the file, but you'll have that number without needing another thread and without doing any additional I/O.
