How to use async methods to load Db Data and keep UI responsive

Question

I made a somewhat large application that works well, except for its UI (winforms) freezes when using webclient to retrieve data from web (link is um... not the fastest), or

Answer 1

never mind. I've got what I wanted with a BackgroundWorker instead:

Public Function GetDatatableUIfree() As DataTable
    Dim connection As New OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\lanserver\storage\DB.accdb;Persist Security Info=False;")
    Dim command = connection.CreateCommand()
    command.CommandText = "SELECT * FROM bdPROC;"
    connection.Open()
    Dim retTable As New DataTable, bgw As New BackgroundWorker, bgw_complete As Boolean
    AddHandler bgw.DoWork,
        Sub(sender As Object, e As DoWorkEventArgs) retTable.Load(command.ExecuteReader)
    AddHandler bgw.RunWorkerCompleted,
        Sub(sender As Object, e As RunWorkerCompletedEventArgs) bgw_complete = True
    bgw.RunWorkerAsync()
    Do
        Application.DoEvents()
    Loop Until bgw_complete
    connection.Close()
    Return retTable
End Function

Thank you very much anyway for the help.
