During windows development, or in fact any similar apps, use the FreeInstance method or DelphiVCL.Application.FreeInstance to deallocate memory allocated by a previous call to the NewInstance method.
All destructors call FreeInstance automatically to deallocate memory that was allocated by overriding NewInstance.
Do not call FreeInstance directly. FreeInstance should be overridden if NewInstance was overridden to change the way the object’s instance data was allocated.
Like NewInstance, FreeInstance uses the value returned from InstanceSize to deallocate the object’s memory.
Let’s browse all the properties and methods of the DelphiVCL.Application.FreeInstance using dir() command:
