Distinct event properties from format, data and others (vba)

Hello,

I'm looping every form and each control in it.
Then I'm looping the properties collection of the control.

Through code, I would like to know if a property of a control in a form is
an event one, or format or data or others (I need event properties only).

MS Access separates them. For example: the tags in the properties window or
the documentation reports tool.

I think name prefix is not a valid method, because there are On, After,
Before... And OCX or ActiveX controls can have their own properties with
their specific names...

Thank you
