que tal compañeros estoy queriendo compilar treedraw.c y la verdad ya le busque un buen rato pero no doy con la solucion que a mi parecer debe ser algo muy simple pero bueno, esto es lo que me arroja al compilar:

undefined symbol "OBJECT" in function HB_FUN_LBSETDATA


Aqui la funcion en cuestion:

HARBOUR HB_FUN_LBSETDATA() // ( hwnd, index, data )
{
_retni( SendMessage( (HWND) _parnl( 1 ), LB_SETITEMDATA, _parni( 2 ),
(LONG) hb_gcGripGet( _param( 3, OBJECT ) ) ) );
}



saludos.
Alex.

Alex,

OBJECT es una variable y no se encuentra definida, hay que definirla al inicio del archivo. Sólo habría que saber de que tipo y valor

William, ese es el problema no se como definirla, ni que tipo sea

gracias por tu respuesta

mi correo de messenger es:

wmormar@hotmail.com

para que charlemos y logremos algo

saludos

Alex,

#define HB_IT_OBJECT 0x08000

gracias Willian, ya te agrege...

Antonio, ya se soluciono el problema de la variable OBJECT pero ahora me dice que no existen las siguientes funciones y estas estan dentro de TREEVIEW.C

unresolved external _HB_FUN_TREEMEASURE
unresolved external _HB_FUN_LBXGETID
unresolved external _HB_FUN_TREEDRAWITEM
unresolved external _HB_FUN_SETMASKED


con excepcion de SETMASKED todas estan dentro de TREEWIEV (aunque les falta una letra pero aun poniendola no funciona)

ANEXO EL TREEVIEW.C
