Chilkat non-ActiveX DLL for Delphi

Chilkat ActiveX DLL for Delphi

* The examples here use the non-ActiveX DLL.

uses
    Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
    Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, SFtp;

...

procedure TForm1.Button1Click(Sender: TObject);
var
sftp: HCkSFtp;
success: Boolean;

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

sftp := CkSFtp_Create();

// To connect through an HTTP proxy, set the HttpProxyHostname
// and HttpProxyPort properties to the hostname (or IP address)
// and port of the HTTP proxy.  Typical port numbers used by
// HTTP proxy servers are 3128 and 8080.
CkSFtp_putHttpProxyHostname(sftp,'www.my-http-proxy.com');
CkSFtp_putHttpProxyPort(sftp,3128);

// Important:  Your HTTP proxy server must allow non-HTTP
// traffic to pass.  Otherwise this does not work.

// Connect to the SSH server through the HTTP proxy.  
success := CkSFtp_Connect(sftp,'sftp.example.com',22);
if (success <> True) then
  begin

// through an HTTP proxy.
