Some problems about word operation
I am trying to use c# doing some operatin with *.doc files. But here are the problems i encountered:
1.There is already an item"Microsoft Word9.0 Object Library " in the COM reference tab.
After i installed the XPpia ,there should be a new item "Microsoft Word 10.0 Object Library ",but there was not.
I use Office 2000.So what 's the problem? What 's the difference if i install pia or not?
Does PIA only fit office xp?
2. I downloaded a program from this website,and run it ,the same error came up as before.
the error line is:aDoc.Application.Documents.Open(ref fn, ref miss, ref miss, ref miss....
and error infor:System.InvalidCastException,QueryInterface failure
I think maybe the environment setting of my computer.So can anybody tell me how to deal with these problems.Thanks
