The FTP functions are only designed to
work on IDCs. In normal display/manager clients, servers, and web
clients, FtpOpen() will always return -1 to indicate
failure. One option is to use the WinInet FTP API installed by
Internet Explorer. However, this would require DLL calls from
CitectSCADA and it could hang CitectSCADA during the FTP upload.
Another option is to install a 3rd party ActiveX control on each
PC. Both options require components that may not exist on the
CitectSCADA PC. An alternative is to use the Windows FTP command to
upload the file using a script. This allows the FTP transfer to run
in a separate thread. And since the FTP command is built in to
Windows there is nothing to install.
The attached Cicode functions use FTP.EXE to upload or download
files. Just copy the code into a Cicode file in your project. It
also requires the ExecEx Cicode function to be copied from Q4572. Then, call FtpUpload or
FtpDownload and pass the FTP server's URL, username, password,
and the paths and filename. See the code for more details and
examples.
