Maurizio,

The linked functions from the LIB are forcing the DLL to get loaded when the application starts. This is automatically performed by Windows.

Hi All,

please, anyone can help me?

Regards,

Kok

[Antonio Linares]

Kok,

You can only use extern "C" when you are compiling a C++ file or in C++ mode.

Simply remove those lines:

LONG GetReaderInfo( LPSTR ,LPSTR ,LPSTR ,LPSTR ,LPSTR ) ;

HB_FUNC(GETREADERINFO)
{
hb_retnl(GetReaderInfo(hb_parc(1),hb_parc(2),hb_parc(3),hb_parc(4),hb_parc(5))) ;
}

Hi Antonio,

After remove as you suggest ,

this warning is appear :

Kok,

Change it this way:

hb_retnl( GetReaderInfo( ( char * ) hb_parc(1), ( char * ) hb_parc(2), ( char * ) hb_parc(3), ( char * ) hb_parc(4), ( char * ) hb_parc(5) ) );

Dear Antonio,

Thank you for your help, the warning is disappear, I will try it with my handheld rfid and let you know later.

Kok

Dear Antonio,

how I can get the return value from hb_parc(1) , hb_parc(2) , hb_parc(3) , hb_parc(4) , hb_parc(5) ?

Hi Antonio,

with below code , GetreaderInfo return 0 ( this is right) , but how i can get the ComAdr ,VersionInfo,ReaderType,TrType and
InventoryScanTime value ?

Kok,

Those are warnings that you can safely ignore

Is the function call working fine ? Do you get an array with the requested info ?
