eventhandling of dynamically created form components

Hello everybody,
after a few hours of googling i decided to ask for help.

Im writing a VBA macro/application (excel 2003) where i dynamically generate components on form. What i need is to handle events (change) of checkbox. I found an perfect example, but it is for ComboBox. Converting to checkbox is severe problem for me.. After trying to change combox to checkbox i get error:

Compile error:
Object does not source automation events

Perfectly working source is following - when replacing two lines by commented ones, i keep gettin error mention above.
