Single to Multi-user conversion(Access)

Hi

I want to make my single-user application to multi-user application,With least amount of change in my code.I have used ms Access 97 as my back end (and i donot to change the back end) and use DAO (jet) to fetch the data on my vb forms.

If any body could guide me with some suggestion's it would be great help to me.


Thanks ahead..
