How to Protect State and Data in a Multithreaded Environment
Interlocked.Increment and Interlocked.Decrement Design applications to try to minimize synchronization needs For many Windows Forms applications, little state protection code may be necessary, because most access of object state happens on the main thread. However, this will not be the case for every application. The System.Threading namespace provides classes and interfaces for synchronizing access to data to provide thread safety. You can use the SynchronizationAttribute on any class that is...
ADONET Objects
ADO.NET evolved from the ADO data access model. By using ADO.NET, you can develop applications that are robust and scalable and that can use XML. ADO.NET has some of the same objects as ADO like the Connection and Command objects , and introduces new objects, such as Dataset, DataReader, and DataAdapter. To move data between a data store and your application, you must first have a connection to the data store. In ADO.NET you can create and manage a connection by using a Connection object....
