Hi, everyone,
        I'v create a toolbar with several buttons contained in a rebar band in WM_CREATE message,well the toolbar display well when max-min the main-window,but while  I click any place in the client area,the toolbar buttons disappeared and only the rebar frame left:

  Do I lost something to repair the rebar?
      Thanks in avdvance!
        Bst regards!

Hi,Miaomiao
    Thanks.althought both are worth studying.    Well,the first tut is not related to rebar control.and the second is based on a dialog.
not suit to my win32 sdi app case.
    Anyway,thanks  a lot
