Question

I’m transferring a file using ftp in Delphi.

I am able to connect to the ftp account ok but when I try and upload a file the
FtpOpenFile function returns nil instead of a handle the file to be uploaded.

hintfile := FtpOpenFile(hintconnect,PChar(tgtfn),GENERIC_WRITE,FTP_TRANSFER_TYPE_BINARY,0);

If I log into the ftp site using an ftp client application and exactly the same credentials I can upload the file without a problem.

Any suggestions appreciated.

Try to get the last error, documentation says it all:

“Returns a handle if successful, or
NULL otherwise. To retrieve a specific
error message, call GetLastError.”
