The best way normally to start learning how to make such systems is to learn basic CRUD with database. We assume that you can create a ms access database.

Select the components you want to reference, and then click OK. But unfortunately when i debugging this code an error is coming ” System. Data Table’ is a ‘type’ but is used like a ‘variable’ ” can you please suggest that how can i improve that…….
