after i get the message that the async operation has been finished, i call the disconnect command. after that i would like to connect to a new site and upload other files, but when i call the asyncupload i get "Asynchronous FTP operation already in progress".
how must i handle this? for how long is the async thread alive?
The async thread is alive until it finishes.
If you feel that Chilkat component/lib is not behaving properly, such as if an async operation begins but never finishes and it seems that it should've, then please let me know. Chilkat would need to reproduce the problem in order to help in these cases.
Wouldn't the purpose of the async be to execute all of your sessions, and then set up and wait for all of them to finish?
