.net - Apache POI Update Custom Fields -

i have used ikvm.net create .net dll apache poi, used update properties of microsoft word 2003 document - author , company , custom fields.

the document references of these fields in content.

for example

ref: account number [account number held in custom field]

when open document have right-click on field , "update field" show new information written poi.

for documents not big deal there going 20+ custom fields need updating. hand not preferable option.

any way in poi update fields they're correct when document opens? or need resort macro of sort fires when document opens?

thanks
