    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    ftp.put_Username(L"login");

    //  In this example, assume that a previous FTP upload failed,
    //  and the incomplete file (bigFile.zip) exists on the FTP server.
    //  You only need to set the RestartNext property to resume
    //  the upload.  When RestartNext is set, the next call
    //  to PutFile (or PutFileFromBinaryData, PutFileFromTextData)
    //  will automatically resume the upload from the point of failure.
    //  (The way it works is that the FTP component sends a "SIZE";
    //  command to the FTP server to find out how many bytes of
    //  the file already exist on the server.  It then begins
    //  uploading from that point.

    //  Note: After PutFile is called, the RestartNext property
    //  is automatically set to false.
    ftp.put_RestartNext(true);

    //  Upload a file with restart.
