REMOVEPROPERTY( ) Function
Removes a property from an object at run time.
REMOVEPROPERTY(oObjectName, cPropertyName)
Parameters
- oObjectName
Specifies the name of the object from which to remove the property. - cPropertyName
Specifies the name of the existing property to remove from the object. You can specify only a property name, not an event or method name.
Return Values
Logical data type. REMOVEPROPERTY( ) returns True (.T.) if it successfully removes the property; otherwise, it returns False (.F.).
Remarks
You can use REMOVEPROPERTY( ) to remove properties, but not methods or events. You can use REMOVEPROPERTY( ) with object instances created from Visual FoxPro classes, COM classes, SCATTER...NAME command, _VFP, and _SCREEN.
Properties must be visibly Public, not Hidden or Protected and have been added to an instance of an object, typically using the ADDPROPERTY( ) function, the AddProperty method, or SCATTER...NAME command, so that they can be removed using REMOVEPROPERTY( ).
You cannot remove a property if it is a member of the class definition used to create the instance of the object.
REMOVEPROPERTY( ) function does not remove properties that are specific array elements. To remove an array, provide only the array name.
