Upload Bytes to an FTP Server (BinData)

See more FTP Examples

Demonstrates the Chilkat Ftp2.PutFileBd method, which uploads the bytes in a BinData to a remote path. The first argument is the BinData and the second is the remote file path. No encoding conversion is performed.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
