You need to import System.ComponentModel for using background worker
Then Declare a private variable
Private bgWorker As New BackgroundWorker
You need to create two methods for background worker's DoWork and RunWorkerCompleted events and assign them.
Private Sub MyWorker_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) 'Add your codes here for the worker to execute End Sub
The below sub will be executed when the worker finishes the job
Private Sub MyWorker_RunWorkerCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) 'Add your codes for the worker to execute after finishing the work. End Sub
Then within your code add the below lines to start the background worker
bgWorker = New BackgroundWorker AddHandler bgWorker.DoWork, AddressOf MyWorker_DoWork AddHandler bgWorker.RunWorkerCompleted, AddressOf MyWorker_RunWorkerCompleted bgWorker.RunWorkerAsync()
When you call RunWorkerAsync() function, MyWorker_DoWork will be executed.
