Anyway I have used the delete sql method to delete data from a database, I want to refresh the data in the form after the record has been deleted. Do I have to close the form and then open an new instance of it? or is there another way I can refresh the data?
today I successfully configured an interface to work with a test database I created in MS Access 2003. The database consists of only 8 records with 10 fields.
I used the basic built-ins with VB 2010 to build the interface in a simple form which shows only 6 of the 10 fields. It all seems to work well, that is the connection string built correctly, and I can run the program and view the individual records. My trouble is that when it goes to the 1st record it's actually the 3rd record in the database. And when I go to the last record it's actually the 2nd record in the database and the next to the last record is actually the first record in the database.
why the program seems to start at the 3 record and shifts the first two records to the end. All the records show up, it's just that they are somewhat out of order.

I have a Form1 that is the main application form, that display certain data from a database. Then I have Form2 that add/delete data from a specific table in the database.My problem is, When I add data to the database, and save it, it work fine, But, it does not reflect on the main form, after I close Form2.

Strategy on how to structure a VB.net GUI app. I have a application that is basically an interface to a database. It is comprised of a TabControl with 6 tabs, each tab has a few custom controls and performs a business operation on the database.
Tab Functions:
CODE:
Common Code Functions:
CODE:
Currently I've got most all of the operations built into event handler functions on the GUI thread. I'd like to move to a more object-oriented structure for code reusability and easier multi-threading.
I'm struggling with a few design things:
What objects / classes makes sense? Are there industry-standard best practices or design patterns around separating GUI and backend functionality? Any particularly good articles I should read? Is BackgroundWorker the best way to execute the backend functions?
