本文介绍了一个使用Delphi编写的SAP登录示例程序。该程序通过TSAPLogonControl组件实现与SAP系统的连接与断开连接。当成功登录时，会启用进一步的操作按钮。

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.
