You can disable or delete the context menu item in MS Word or Excel by VBA programming.

Word:

OA1.CreateNew “Word.Document”
Set objWord = OA1.ActiveDocument
objWord.Application.CommandBars(”Text”).Controls(”Cu&t”).Enabled = False
objWord.Application.CommandBars(”Text”).Controls(”&Copy”).Enabled = False
objWord.Application.CommandBars(”Text”).Controls(”&Paste”).Enabled = False
‘delete item directly
‘objWord.Application.CommandBars(”Text”).Controls(1).Delete
‘objWord.Application.CommandBars(”Text”).Controls(2).Delete ….

Excel

OA1.Open “c:\text.xls”
Set objExcel = OA1.ActiveDocument
objExcel .Application.CommandBars(”Cell”).Controls(”Cu&t”).Enabled = False
objExcel .Application.CommandBars(”Cell”).Controls(”&Copy”).Enabled = False
objExcel .Application.CommandBars(”Cell”).Controls(”&Paste”).Enabled = False
‘delete item directly
‘objExcel .Application.CommandBars(”Cell”).Controls(1).Delete
‘objExcel .Application.CommandBars(”Cell”).Controls(2).Delete ….
