TObject, DLL, DLL Freigabe

Im Grunde sehr einfach:

Delphi-Quellcode:

  IMasterDeviceVersion = interface
  ['{DF6962EE-B638-4B59-9BE6-82B8BB369477}']
    function GetAppVersion: WideString;
    function GetModel: WideString;
    function GetSysVersion: WideString;
    procedure SetAppVersion(const Value: WideString);
    procedure SetModel(const Value: WideString);
    procedure SetSysVersion(const Value: WideString);

    property Model: WideString read GetModel write SetModel;
    property AppVersion: WideString read GetAppVersion write SetAppVersion;
    property SysVersion: WideString read GetSysVersion write SetSysVersion;
  end;

  TMasterDeviceVersion = class(TInterfacedObject, IMasterDeviceVersion)
  strict private
    var
      FModel: WideString;
      FAppVersion: WideString;
      FSysVersion: WideString;
    function GetAppVersion: WideString;
    function GetModel: WideString;
    function GetSysVersion: WideString;
    procedure SetAppVersion(const Value: WideString);
    procedure SetModel(const Value: WideString);
    procedure SetSysVersion(const Value: WideString);
  public
    property Model: WideString read GetModel write SetModel;
    property AppVersion: WideString read GetAppVersion write SetAppVersion;
    property SysVersion: WideString read GetSysVersion write SetSysVersion;
  end;

Und dann:

Delphi-Quellcode:

procedure ParseVersion(const aText: PChar; MasterVersion: IMasterDeviceVersion); stdcall;
//

Du darfst dann natürlich auch in der Anwendung nur noch mit IMasterDeviceVersion usw. arbeiten.
