[VB] backgroundworker

Mene pa zanima, kako narediti backgroundworker da bo unikaten in uporaben za multithreading. recimo da za vsako novo povezavo narediš nov backgroundworker na tak način, da ti pri ustvarjanju novega ne napiše da je busy.

jaz sem naredil recimo takole...

    Sub MTconnectp(ByRef processval As BackgroundWorker)
        processval = New BackgroundWorker With {.WorkerReportsProgress = False, .WorkerSupportsCancellation = True}
        AddHandler processval.DoWork, AddressOf MTconnect_DoWork
        AddHandler processval.RunWorkerCompleted, AddressOf MTconnect_done
    End Sub

MTconnectp(user(d_mtserver.ColumnName)(1))
IF ukaz kjer preverim če je worker busy.
user(d_mtserver.ColumnName)(1).RunWorkerAsync({user(d_mtserver.ColumnName)(0), user(c_server.DataPropertyName), user(c_port.DataPropertyName), user(c_hash.DataPropertyName), user(d_mtserver.ColumnName)(1)})


zadeva je v loopu in mi pri if ukazu pravi da je worker busy. v čem je fora?
pa tisti parametri ki jih podam v arrayju bg workerju so različni.
