PROPERTYAVAILABLE
Lets form and application developers know when an invalid reference to a property has taken place or is about to take place. This allows developers to develop in such a way that they can choose either:
- To bypass the property referenced by this function (by checking before the property is actually referenced), when an invalid return is indicated; or
- To check whether an invalid value was returned from the referenced property (by checking after the value is returned).
Return Value
Boolean
A value of TRUE indicates that the property and/or its return value is available. A value of FALSE indicates that the property and/or its return value is not available.
Syntax
