Well it is on TODO list, but actually WinSCP is too far from having stable API to allow development of DLL.
Hi,
WinSCP is a very nice tool, but in the fact you will automate a FTP/SFTP upload using your own application.
Of course you can use the command line features of WinSCP but the problem is you want to run each command step by step and check the return code of command!
I am searching for a DLL or ActiveX component for SFTP but there are very expensive! So maybe you can change your WinSCP a little bit and create a DLL or ActiveX component for FTP/SFTP?
Thanks
