_SetObjectProperty( ) API Library Routine

  • Articolo

Sets a property for an object.

int _SetObjectProperty(Value FAR *objct, char FAR *prop, Value FAR *val,
   int fAdd)

Remarks

The first parameter *objct is an object reference; the second parameter *prop is the name of the property to set; the third parameter *val is the new property value.

The last parameter fAdd is either 0 or a non-zero value that specifies if the property is added to the object if the property does not exist. If fAdd is a non-zero value and property you specify does not exist for the object, the property is added to the object as a user-defined property, and contains the property value you specify with *val. If fAdd is 0 and the property you specify does not exist for the object, the property isn't added to the object.

_SetObjectProperty( ) returns 0 if it is successful; otherwise, the negative value of the corresponding Visual FoxPro error code is returned.
