For the last twenty years, it’s been clear that improving poorly written queries plays a bigger role in best practice designs than any other single issue. The impact of a 100,000 row query on an ADO.NET application is no less

Antonio M. Mora,Giovanni Squilleroresultset data to some other tier. I expect that most of you work with applications where you need to change the data from time to time. This chapter focuses on the mechanics of persisting your changes to a data source or transporting your in-memory DataTable or DataRow data. Remember that ADO.NET i

Lecture Notes in Computer Scienceloper can still use the On Error GoTo syntax, it might not make much sense in light of how .NET exposes exceptions. Frankly, as long as On Error management evolves in Visual Basic .NET it remains moving target. Many fundamental On Error features were not implemented in the beta versions, which creat

The concepts and code discussed and illustrated here apply (in most cases) to.NET Windows Forms and ASP Web Services and other ADO.NET platforms.
