[NumLock]

честный код:

Код:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

const
  LOGON_WITH_PROFILE = $00000001;
  LOGON_NETCREDENTIALS_ONLY = $00000002;

function CreateProcessWithLogonW(
    lpUsername: LPCWSTR;

var

  else Result:=GetLastError;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage(SysErrorMessage(RunWithLogon('Test', '', '123', 'c:\WINDOWS\NOTEPAD.EXE')));
end;

end.
