Is there a way to read/update document custom properties?
Say I have a document that has fields inserted into the text (with DOCPROPERTY) that are pointing to a custom document property. I would like to open the document, update the custom document properties and then do an update of all fields (I found I can trigger the update thru UpdateFields method or when Exporting by setting the appropriate flag).
I have not found any mention in the documentation about how I would be able to update an existing document custom property. Could someone point me in the right direction?
