    1. ShowWindow can be used for any window.
    2. Yes, you should create the control member variables for all the controls you are going to manipulate.

    All visible components are derived from CWnd... so you can use ShowWindow () on your dialog AND on all your child components that are on your dialog.

    May be you have to use GetDlgItem(Control_ID)->ShowWindow(SW_HIDE or SW_SHOW)

    Hope this helps,

    Thanks.

    No, neither OP nor you should use GetDlgItem, except for some rare cases (and this one does NOT belong to this exception).
    Use control member variables!
