I'm usually happy to answer questions directly, but I find most questions that are really pertinent for everyone.

But can you use the same APIs from, for example, a custom task pane within the Office application? E.g. when you have a new document, can you access it via the Packaging APIs or should you then use the COM and VBA APIs? <br> <br>Regards, <br> <br>Onnohttp://blogs.msdn.com/kevinboske/archive/2006/03/11/549736.aspx#560102Fri, 24 Mar 2006 20:13:50 GMT91d46819-8472-40ad-a661-2c78acb4018c:560102KevinBoskeGreat question! <br> <br>Well, the Packaging API's are for accessing files on disk. &nbsp;Yes, you could do this from a CTP, however, you'd be accessing another file (not the file that might be the Active document, for instance). &nbsp;Once the file is loaded into an Office client, you then need to use COM/VBA and the client object model.http://blogs.msdn.com/kevinboske/archive/2006/03/11/549736.aspx#562012Mon, 27 Mar 2006 18:26:44 GMT91d46819-8472-40ad-a661-2c78acb4018c:562012OpenXML DeveloperLinks to blog posts that contain useful technical information for developers. &nbsp;Open XML is a new standard, but there's some good information already available if you know where to look.
