A fairly generic question:
Hi,
Thanks for your query.
Well, I am not sure if you can use a .NET library (e.g Aspose.Cells.Dll) in VBA of Access. Anyways, see the following documents on how to register Aspose.Cells library and how to use Aspose.Cells for .NET via COM interop.:
http://www.aspose.com/docs/display/cellsnet/Using+the+COM+Interface
http://www.aspose.com/docs/display/cellsnet/Using+Aspose.Cells+for+.NET+via+COM+Interop
Hope, this helps a bit.
Thank you.
