1、新建一个Form，并在form上添加下列控件

Component Function SAPLogOnControl1 SAP ActiveX-Component to logon to the system Button1 Button to start the procedure

2、源代码如下
unit s_logon;

interface

uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
ExtCtrls, OleCtrls, SAPLogonCtrl_TLB, StdCtrls,Grids ;

type
  TForm1 = class(TForm)
  SAPLogonControl1: TSAPLogonControl;
  Panel1: TPanel;
  StaticText1: TStaticText;
  Button1: TButton;
  procedure SAPLogonControl1Click(Sender: TObject);
  procedure Button1Click(Sender: TObject);
private
{ Private-Deklarationen }
public
{ Public-Deklarationen }
end;

var
Form1: TForm1;
Connection :variant;

implementation

{$R *.DFM}

procedure TForm1.SAPLogonControl1Click(Sender: TObject);
begin

  (* define connection *)
  Connection:= SAPLogOnControl1.NewConnection;

  (* start LogOn *)
  if Connection.LogOn(0,false) = true then

  begin
    showmessage('Logon O.K.');
    Button1.Enabled:= true;
  end
  else
  begin
    ShowMessage('Error on Logon :-(((');
    SAPLogonControl1.Enabled:=true;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin

  (* cut connection *)
  Connection.LogOff;

  ShowMessage('System LogOff...');
  SAPLogonControl1.Enabled:=true;
  Button1.enabled :=false;
end;
end.
