[toms]

Hallo,

Hier mal ein Beispiel:

Unit1:

Delphi-Quellcode:

unit Unit1;

interface

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

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

var
  Form1: TForm1;

implementation

{$R *.dfm}

uses
  Unit2;

procedure TForm1.FormCreate(Sender: TObject);
begin
  ShowMessage(GetWinDir);
end;

end.

Unit2:

Delphi-Quellcode:

unit Unit2;

interface

function GetWinDir: string;


implementation

function GetWinDir: string;
var
  Len: Integer;
begin
  Result := '';
  Len := Windows.GetWindowsDirectory(nil, 0);
  if Len > 0 then
  begin
    SetLength(Result, Len);
    Len := Windows.GetWindowsDirectory(PChar(Result), Len);
    SetLength(Result, Len);
  end;
end;

end.
