Question

my current solution as you can see is by using shared variable within a class in order to pass a value.

on the form load of my application i called: workerSample.RunWorkerAsync

Dim finalList As List(Of String)
Private Sub workerSample_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles workerSample.DoWork
    Dim xList As New List(Of String)
    'long process of finding folder which contains executable files
    finalList = xList
End Sub

Private Sub workerSample_RunWorkerCompleted(ByVal sender As System.Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles workerSample.RunWorkerCompleted
    'do something with finalList
End Sub

is there another way to pass xList variable to RunWorkerCompleted by using an argument?

Answer 1

Dim finalList As List(Of String)

Private Sub workerSample_DoWork(sender As System.Object, e As System.ComponentModel.DoWorkEventArgs) Handles workerSample.DoWork
    Dim xList As New List(Of String)
    e.Result = xList
End Sub

Private Sub workerSample_RunWorkerCompleted(sender As System.Object, e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles workerSample.RunWorkerCompleted
    Me.finalList = e.Result
End Sub
