Saving Data to a custom file

Hello all,

I have an application that collects data from the user and reads data from the serial port. After the user has entered the data and the data from the serial port received, I would like to be able save those data into a file, preferably in some database format (e.g. Access mdb file) Can anyone help me with this, I am very confused with vb.net. I have created an Access database and connected it to my "solution", I also have created a datagridview on the form that connects to a table in the database. Now I basically want add two buttons (or menu items) on the form, one that does a "Save As" and allows all of that data to be saved into a separate mdb file, and one "New" button that opens a blank copy of the mdb file for more data to be entered.

Can anyone give me some pointers on where to even begin?

Thanks
