posted November 10, 2016 4:57 AM I'm using Dart.ftp for .NET v4.7.1.0 and I'm having the following problem; I use the control in a dll that is run by a service. I use it to setup a secure connection (Explicit) and setup the .Security.ValidationCallback to point to the correct function to handle the validation callback. Now when the function is run to connect to an ftps-server, retrieve a filelist and disconnect everything seems to work fine. However, when I now stop the service which is initiating the dll that performs the FTPS-function, the service crashes and I get error entries in the eventlog (see bottom). Also if the service runs the plugin a couple of times to get the filelist from the FTPS-server the program will crash after a few times the command is run. If I run the plugin without set .Security.ValidationCallback the program never crashes, but ofcourse then the connection can't be validated. This is now a big problem for me. What could be the problem? If I use the sample FtpListView winforms program I get the exact same problem; when I quit the program I get the same errors in the eventlog. I hope anyone can help!

posted November 10, 2016 7:51 AM I have the same problem with the test program "ParallelTransfers" and I have tested it on different computers (windows 10 & Server 2012R2). The eventlog errors appear when the program is closed. |

posted November 11, 2016 4:06 AM Hi Jamie, thanks for looking into this. I have emailed the extra info to support@dart.com Some more info: I get the same result with two different external ftps-servers. I haven't been able to test with other servers. It's not that my program (or the sample programs) show a crash-report when you stop the program. Everything seems fine when stopping the program, so nothing strange there. But when you then look in the application eventlog the errors are there. And for my service application this causes the service to crash. |

posted November 14, 2016 5:38 AM Hi Jamie, Do you have any idea when you can look into this? This is turning into a big problem because my clients can't use FTPS at the moment. Thanks! |
