Can you expand on where, or what the uni-code problem is?
Data is stored in ms-access in uni-code. However, depending on how code uses
the data, it can certainly be an issue (and, can be difficult to work with).
There is no such thing as VBA.net. However, there is most certainly vb.net.
If you going to use vb.net, then you in the wrong place, and wrong
newsgroup. You can certainly consider using vb.net, but that has no relation
to ms-access at all.
