Win32/64 COM-Port component for Delphi

comportdriver's Issues

64bit windows, Exception 'Range check error'

Range check error on FHandle assignment (, see below:

constructor TCommPortDriver.Create(AOwner: TComponent);
begin
  inherited Create(AOwner);
  // Not connected
  FHandle                    := INVALID_HANDLE_VALUE;  <<< BOOM

FHandle is defined as HFILE, which is defined as LongWord. Change to THandle.

  TCommPortDriver = class(TComponent)
  protected
    /// <summary>
    ///   Device Handle (File Handle)
    /// </summary>
    FHandle                    : THandle; <<< Here and elsewhere. 

Dispenser.pas

sorry, false project

Could it compile for Lazarus?

Hello Mhumm, how are you?
I would like to congratulate you for the component, I already used it in Delphi many years ago. I currently work with Lazarus. Would it be possible for you to compile this code, generating a component to be used in Lazarus? It would be very important to me. How much would this work cost?

I await your reply.

Does this work on FireMonkey?

I know it's Win32/64 only, but would it work on FireMonkey (FMX) for Win32/64?

Not able to compile the demo

The error is: [dcc32 Error] E2161 Error: RLINK32: Unsupported 16bit resource in file "...\ComPortDriver\Demo\MnForm.DFM". The Delphi version I'm using is 11.1.
