I'm using the Access Database format .accdb?
1. Can I just create a database by creating the file: "<db name here>.accdb"?

With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.

Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file

View 6 RepliesI would like to generate an Excel file using a database query in VB.Net. How can I do it? To be more precise: I would like to "bind" a query (much like binding a query to a GridView) to an Excel file such that the rows in the table occupy corresponding cells in a new Excel file, and save the file to my computer.
