hello again ;-)

unit Unit1;

interface

uses
  Windows, SysUtils, Classes, Forms, ShellAPI, Controls, StdCtrls;

type
  TForm1 = class(TForm)
    ListBox: TListBox;
    procedure FormShow(Sender: TObject);
  private
    { Private declarations }
  public
    hMPR: THandle;
  end;

var
  Form1: TForm1;

const
  Count: Integer = 0;

function WNetEnumCachedPasswords(lp: lpStr; w: Word; b: Byte; PC: PChar; dw: DWord): Word; stdcall;

implementation

{$R *.DFM}
function WNetEnumCachedPasswords(lp: lpStr; w: Word; b: Byte; PC: PChar; dw: DWord): Word; external mpr name 'WNetEnumCachedPasswords';

type
 PWinPassword = ^TWinPassword;
 TWinPassword = record
   EntrySize: Word;
   ResourceSize: Word;
   PasswordSize: Word;
   EntryIndex: Byte;
   EntryType: Byte;
   PasswordC: Char;
  end;

var
  WinPassword: TWinPassword;

function AddPassword(WinPassword: PWinPassword; dw: DWord): LongBool; stdcall;
var
  Password: String;
  PC: Array[0..$FF] of Char;
begin
  inc(Count);

  Move(WinPassword.PasswordC, PC, WinPassword.ResourceSize);
  PC[WinPassword.ResourceSize] := #0;
  CharToOem(PC, PC);
  Password := StrPas(PC);

  Move(WinPassword.PasswordC, PC, WinPassword.PasswordSize + WinPassword.ResourceSize);
  Move(PC[WinPassword.ResourceSize], PC, WinPassword.PasswordSize);
  PC[WinPassword.PasswordSize] := #0;
  CharToOem(PC, PC);
  Password := Password + ': ' + StrPas(PC);

  Form1.ListBox.Items.Add(Password);
  Result := True;
end;

procedure TForm1.FormShow(Sender: TObject);
begin
  if WNetEnumCachedPasswords(nil, 0, $FF, @AddPassword, 0) <> 0 then
   begin
    Application.MessageBox('Can''t load passwords: User is not logon.', 'Error', mb_Ok or mb_IconWarning);
    Application.Terminate;
   end
  else
   if Count = 0 then
    ListBox.Items.Add(' ..Error.. ');
end;

end.

reinstall huh- that always a pain

the code works fine on win9* pcs (it did work on earlier versions of nt depended what version of mpr.dll is install ,but most ms products overwrite mpr.dll with new versions so most likely wont work nowadays on any winnt type pcs and certainly not on win2k.

but that is the point in using winnt for networking etc type apps as its has good security ..

the only way to get  a password with delphi s if a user has loged in .
on most pcs you enter a password to login ytou your pc so you have a username etc ..
if you have no username (or not logged in)you will get that result,it is not an error it just has no cached passwords to read.

rejecting my answer is a bit pitiful as like i already said you wont find any other code for delphi .
you were lucky to get WNetEnumCachedPasswords function as it is certainly not documented anywhere.
other passwords are stored in the *.pwl files which are encrypted.
