Something is wrong ... ...... private FWindowHandle: HWND; ........ function USBRegister: Boolean; procedure Register; protected procedure WMDeviceChange(var Msg: TMessage); ......... 2° I added in the implementation section (the last procedure): ....... if Assigned(r) then Result := True; end; procedure Register; begin RegisterComponents('Samples', [TComponentUSB]); end; end. 3° I tried to install the component but an error occurred near the line in implementation section where i added 'procedure register'. Unsatisfied forward or external declaration: 'TComponentUSB.Register' Help!! Related Articles and Replies
