Description
The REMOVEPROPERTY() function is used to remove a property from an existing object. It returns .T. (True) if the property was successfully removed and .F. (False) otherwise.
| Parameter | Description |
|---|---|
| <object-name> | The name of the object. |
| <expC> | The name of the property to be removed. |
All classes also have an inbuilt removeproperty method. This can be used as an alternative to the REMOVEPROPERTY() function to remove properties from an object at runtime.
<object-name>.removeproperty(<expC>)
Properties can be added using the ADDPROPERTY() function or inbuilt addproperty method.
Example
define class myclass as custom myprop = "Hello World" enddefine myobject = createobject("myclass") Messagebox(myobject.myprop) addproperty(myobject, "myprop2", "goodbye") // Or: myobject.addproperty("myprop2", "goodbye") Messagebox(myobject.myprop2) removeproperty(myobject, "myprop2") // Or: myobject.removeproperty("myprop2")
Products
Recital, Recital Server
