Upload Bytes to an SFTP Server (BinData)

See more SFTP Examples

Demonstrates the Chilkat SFtp.UploadBd method, which uploads all bytes in a BinData to a remote file. The first argument is the BinData and the second is the remote file path.

Note: This example uses relative local paths, which are resolved against the application's current working directory. Absolute local paths may also be used. Supply the paths appropriate to your own environment.
