# Listen for messages sent by this would involve working with the
# SetWindowLong function. This can be accessed via the win32gui or through
# ctypes. You can find examples on how to do this by searching for
# `Accessing WGL_WNDPROC` on the internet. Here are some examples of how
# this might work:
#
# # using win32gui
# import win32con
# import win32gui
# old_function = win32gui.SetWindowLong(window_handle, win32con.GWL_WNDPROC, new_function)
#
# # using ctypes
# import ctypes
# import win32con
# from ctypes import c_long, c_int
# user32 = ctypes.WinDLL('user32', use_last_error=True)
# WndProcType = ctypes.WINFUNCTYPE(c_int, c_long, c_int, c_int)
# new_function = WndProcType
# old_function = user32.SetWindowLongW(window_handle, win32con.GWL_WNDPROC, new_function)
broadcast_message = ctypes.create_unicode_buffer(message)
user32 = ctypes.WinDLL('user32', use_last_error=True)
