Actualmente cambio los atributos mediante MS-DOS Run "ATTRIB &fName +R" pero al estar usando el entorno grafico no es estético ver aparecer una ventana negra. ¿hay otra forma de hacerlo?

I change the attribute file with MS-DOS Run "ATTRIB &fName +R" but it show a black window that i don't like. another method?

shellexecute(0,'open','Touch.exe','rest*.dbf /D '+V2S(DATE())+' /T '+TIME(),,0)

Pones 0 (cero) el ultimo parametro y no debe aparecer la ventana de DOS

Gracias, las 2 opciones me funcionaron

* src/rtl/Makefile
+ src/rtl/xfile.c
+ added PRG interface to Harbour FILE IO API
The following PRG functions are available for Harbour programmers:

HB_VFOPEN( <cFileName>, [ <nMode> ], [ <nAttr> ] ) -> <pHandle> | NIL
HB_VFCLOSE( <pHandle> ) -> <lOK>
HB_VFLOCK( <pHandle>, <nStart>, <nLen>, [ <nType> ] ) -> <lOK>
HB_VFUNLOCK( <pHandle>, <nStart>, <nLen> ) -> <lOK>
HB_VFLOCKTEST( <pHandle>, <nStart>, <nLen>, [ <nType> ] ) ;

HB_VFREAD( <pHandle>, @<cBuff>, [ <nToRead> ], [ <nTimeOut> ] ) ;

HB_VFWRITE( <pHandle>, <cBuff>, [ <nToWrite> ], [ <nTimeOut> ] ) ;

Especialmente estas:

HB_VFATTRGET( <cFileName>, @<nAttr> ) -> <lOK>
HB_VFATTRSET( <cFileName>, <nAttr> ) -> <lOK>

Aunque creo que han cambiado de nombre.

Salu2,
