Determines if an object has a specified property
(vlax-property-available-p obj prop [check-modify])
Arguments
A VLA-object.
A symbol or string naming the property to be checked.
If T is specified for this argument, vlax-property-available-p also checks that the property can be modified.
Return Values
T, if the object has the specified property; otherwise nil. If T is specified for the check-modify argument, vlax-property-available-p returns nil if either the property is not available or the property cannot be modified.
Examples
The following examples apply to a LightweightPolyline object:
_$ (vlax-property-available-p WhatsMyLine 'Color)
T
_$ (vlax-property-available-p WhatsMyLine 'center)
nil
The following examples apply to a Circle object:
_$ (vlax-property-available-p myCircle 'area)
T
Note how supplying the optional third argument changes the result:
_$ (vlax-property-available-p myCircle 'area T)
nil
The function returns nil because, although the circle has an “area” property, that property cannot be modified.
The vlax-method-applicable-p and vlax-put-property functions.
