Comentários

When Buttons is Custom, Show always returns Cancel. Use CustomDialogResult to determine which button the user clicked.

When a null Nothing nullptr unit uma referência nula (Nothing no Visual Basic) value is supplied for Owner, the exception message box appears on the Windows Taskbar. We recommend that you pass the parent window object instead.
