Hi GG, Thanks for your reply. In your mailing list, you suggest me demonstrating what I want to do, so now I am describing it in detail, please see below. I want to receive data from FTP servers over a network with CFFTP API, and can safely stop transferring data at any time. Firstly, create the stream using CFReadStreamCreateWithFTPURL(). Secondly, set up my callbacks with CFReadStreamSetClient(). Thirdly, add it to the run-loop with CFReadStreamScheduleWithRunLoop(). Finally, open the stream with CFReadStreamOpen(). I'll get call-backs when information is available to be read. I can accomplish receiving data from FTP servers successfully. When transferring data, I stop it using CFReadStreamUnscheduleFromRunLoop() and CFReadStreamClose(). When I am resuming to connect the same file in FTP servers, I always get the same problem which show error code 530 that meams user not logged in. However, I can connect other files in FTP servers successfully. I guess the reason why I can not connect the same file again is that I did not interupt the read stream safely. So my question is...How can I resume to connect and receive data from the same file in FTP servers or how can I interupt the read stream safely. Here is my msn identifier chrisgard...@live.com if you could add me. Waiting for your reply.
