Hello all,
i have a problem with Free edition.
I made a program wich on schedule dows some FTP downloads.
When i start the program it runs fine, and i can do the transfers.
Then if i wait a minute and process the files again i get an exeption.
If i wait 5 mins it works fine but i think that weird because im using .close(true) and disposing the object.
If i quickly quit program and restart i can download within one minute.
Dim ftpconn As New FTPConnection
ftpconn.ServerAddress = Host
ftpconn.ServerPort = 21
ftpconn.UserName = username
FTPConnection.LogLevel = EnterpriseDT.Util.Debug.LogLevel.Debug
FTPConnection.LogFile = "C:\test123.txt"
ftpconn.Password = Password
ftpconn.Connect() <=============================== Sorry, the maximum number of connections (2) for your host are already connected. (code=530)
ftpconn.DownloadFile(dest, source)
ftpconn.Close(True)
ftpconn.Dispose()
The log shows that it has succesfull downloaded 2 instances and had closed the connections.
