  _printEx.h

  
    HACK!


    We need to add support for NT5 PrintDlgEx function but turns out
    that the corresponding headers are included for WinVER = 0x0500 ..
    but since WAB is being built with 0x0400, we can't include the
    headers directly - so we have included a copy of the PrintDlgEx

    At some point of time we should remove this copy and just use
    commdlg.h

//  IPrintDialogCallback Interface
//
//  IPrintDialogCallback::InitDone()
//    This function is called by PrintDlgEx when the system has finished
//    initializing the main page of the print dialog.  This function
//    should return S_OK if it has processed the action or S_FALSE to let
//    PrintDlgEx perform the default action.
//
//  IPrintDialogCallback::SelectionChange()
//    This function is called by PrintDlgEx when a selection change occurs
//    in the list view that displays the currently installed printers.
//    This function should return S_OK if it has processed the action or
//    S_FALSE to let PrintDlgEx perform the default action.
//
//  IPrintDialogCallback::HandleMessage(hDlg, uMsg, wParam, lParam, pResult)
//    This function is called by PrintDlgEx when a message is sent to the
//    child window of the main page of the print dialog.  This function
//    should return S_OK if it has processed the action or S_FALSE to let
//    PrintDlgEx perform the default action.
//
//  IObjectWithSite::SetSite(punkSite)
//    IPrintDialogCallback usually paired with IObjectWithSite.
//    Provides the IUnknown pointer of the site to QI for the
//    IPrintDialogServices interface.
