1.Are exceptions used to indicate error rather than returning status or error codes?
2.Are all classes and public methods commented with .NET style comments? Note that <summary> comments should discuss the "what" of public methods. Discussion of "how" should be in <remarks> blocks or in-line with the code in question?
3.Are method arguments validated and rejected with an exception if they are invalid?
4.Are Debug.Asserts used to verify assumptions about the functioning of the code? Comments like, "j will be positive" should be rewritten as Asserts.
5.Do classes that should not be instantiated have a private constructor?
6.Are classes declared as value types only infrequently used as method parameters, returned from methods or stored in Collections?
7.Are classes, methods and events that are specific to an assembly marked as internal?
8.Are singletons that may be accessed by multiple threads instantiated correctly?
9.Are methods that must be overriden by derived classes marked as abstract?
10.Are classes that should not be overriden marked as sealed?
11.Is "as" used for possibly incorrect downcasts?
12.Do classes override ToString instead of defining a Dump method for outputting the object's state?

I'm new to VB and using a datagridview for the first time. I've spent the last 2-3 days trying to get row deletion to work and can't do it. I've tried every piece of code I can find on the internets, and none of them are doing it.I have the selection mode set for full row, with a delete button on the form. Clicking it will delete the row from the DGV, but the changes are not going back to the database. Here is the code I'm using right now in my delete button event handler:

The row disappears from the DGV, but not from the database. I've gone back and started from scratch a few times now
how to go about the code for a button to delete the row in a datagridview. i have rows of data in there with a button at the end of the row. the difficulty im having is assigning the values in the row to delete it from the data grid and then update the database to remove the entry.i've tried this but it doesnt work? i'm sure there will be some short statement to do it but dont know what it is.

I have a VB 2008 program over the Northwind DB customer table.It uses LINQ to add, delete and edit records.
So I load everything into a datatable/dataset first.The Add and Delete occurs when the buttons are clicked on a binding navigator. The edit occurs when a cell is changed, and that row is clicked off. I've set the Customer ID field as the primary key in the DT. I then bind everything together with a binding mavigator.
So far so good, Adding & Editing works nicely the DGV & customer table . [code]...
