This software allows for subclassing of window forms, allowing users to intercept and execute messages. Additionally, the software enables the supplementation or substitution of system administered messages.

The window function, which determines the behavior of a window and its reaction to user inputs, is completely replaced or supplemented by the Subclassing component depending on the value of the StopMessage parameter. If set to True, the original window function is stopped and replaced, while if set to False, the original function is complemented, which is also called Superclassing.
With the Subclassing component, developers can easily modify the behavior of window functions to create unique and custom user experiences. This utility is a valuable addition to any software development toolkit, especially for those looking to add new functionality to window-based applications.
