Hello All, I am using c# (.net 2.0) and VS 2005 Office 2007 (Word,excel and ppt) I wanted to trap click event of existing buttoin in Word,Excle and ppt toolbar. 1)user open word 2)user writes some data in new document or existing doc 3)user clicks on "Publish" button 4)user clicks on "Document Managment Server" ( during this document is not saved locally but direclty to specified server) I want to trap this event and want to change some document custome properties and then execute normal flow. If it is not possible - on DocumentBeforeSave event handler - can i check if this method is called by which button - like 'Save' or 'Save as' or 'Publish-Document Managment Server' ? Thanks in advance. regards UHS
