Is it possible to edit data in ITEMS in CE using VBA

I am trying to use VBA to edit data contained in ITEMS in Connect Edition, is that possible?

I have tried using the PropertyHandler and it allows me to read the data, but does not allow me to write back to it.

I am using the code oPH.Set.Value (sNewPropertyValue) and it throws the error, "illegal operation for this type"

This process is to replace my TAGS editing functions.

Is there any alternative ways to do this?

Regards,

John Davidson.
