That way, I would have a generic dialog for the UI somewhere and the logic (transfer) here in this file, where it belongs. Unfortunately, this doesn't work. I have to block this function until the transfer is done, but have the transfer itself and the progress UI working. darin says, I will get threading issues then. He suggested to initiate the transfer from the dialog (because that dialog uses another event quene) and let the dialog close itself when the transfer is done. Here in this function, I can block until the dialog is dismissed. (At least, that's what I understood from darin.) That's what I do, and it seems to work. It's still a poor design. Actually, it's really crap. It destroys my whole design with the pluggable "method"s (like stream, copy etc.).
