We current use Office XP and have no immediate plans to migrate to a more
current version of Office.

We have Word and Excel documents that use a lot of VBA code.

Will VBA code be supported in Office 2007? Will VBA code be supported in
later versions of Office? Does Microsoft have a project lifecycle that
states how long VBA code will be supported?

Is VSTO the VBA replacement? Will VSTO work in Office XP? To go from VBA
to VSTO will we have to rewrite all of the VBA code (similar to the extensive
rewriting required for VB6 to DotNet)?

Thanks
