I only have one issue at the moment, when I attempt to set the value of the BuiltInDocumentProperties Category it fails; however, I am able to set the other properties such as Comments, Keywords, Subject, etc. Is there a different name I am supposed to use other than Category?
doc.BuiltInDocumentProperties[“Category”].Value = strdotCategory;
Ok, I see this. For some properties, looks like if it was never set in a document, it will not be in the list of built in properties and Aspose.Word does not let to create built in properties.
The workaround is to edit the document in MS Word to set and then clear (if you want) the document property in question such as Category.
I will add this issue to be fixed so the missing builtin properties will be automatically created by Aspose.Word.
