Creating VB. NET threads to access databases

Database applications, especially network database access, because of the large amount of data that may need to be accessed, so it takes a long time to get results, and a good program should have good interactivity, when accessing the database should allow your application to respond to user activities as soon as possible to provide a rich user experience. Multithreading allows time-consuming operations to run in the background to respond quickly to user activity. The following code accesses the database and returns the data table:

Private sub GetDataFromDataBase() … m_table.Clear() m_sqlDataAdapter.Fill(m_table) … End Sub

To create a new instance of a Thread object, create a new thread agent.ThreadStart thread agents can specify the name of the method to execute when the thread is spawned, but thread agents do not actually run the thread. When you create a ThreadStart object, you specify a pointer to the method to run when the thread starts execution, which cannot accept any parameters. Let's assign the above code to a thread and start it:

Dim myThreadStart as ThreadStart =New ThreadStart(AddressOf GetDataFromDataBase) Dim myThread as Thread=New Thread(myThreadStart) myThread.Start()

This allows the user to continue processing while the VB. NET thread accesses the database.
