Dim work As New EventHandler(AddressOf WorkHandler)bgwExecute.RunWorkerAsync(work)

B.
Dim tsBackground As New ThreadStart(AddressOf WorkHandler)bgwExecute.ReportProgress(0, tsBackground)

C.
Dim tsBackground As New ThreadStart(AddressOf
WorkHandler)bgwExecute.RunWorkerAsync(tsBackground)

D.
AddHandler bgwExecute.DoWork, AddressOf WorkHandlerbgwExecute.RunWorkerAsync()
