    Is the manufacture scan interface should hold or can return immediately according to TWAIN specification ?

    I found when invoke some manufacture Scan user interface, some return immediately, some hold until the use done with scan
    rcResult = Twain.Win32.DSuserif(p_oApp, p_oDataSource, Twain.TwDG.Control, Twain.TwDAT.UserInterface, Twain.TwMSG.EnableDS, p_oGUI)

    Also the way to send parent application message is different, some of the message could not be trapped by the parent window.

    Like Twain.TwainCommand.TransferReady

    Not be able to trap the message in parent window application message loop.
