MFC OnUpdateUI called before WM_CREATE

Question

hi in my mfc app i creates a clistctrl object in OnCreate message of main frame and in some OnUpdateUI fnctions i used that list ctrl.GetItemCount() for example to enable or disable a menu item. but today i runned app in debug mode the OnUpdateUI function asserted by debuger and the list ctrl wnd handle was NULL! i think onupdateui called before OnCreate so this is normal or it is mfc bug? how this possible?! thanks

If I remember correctly the update handlers are called from OnIdle, so I'd assume it is possible and you should check the handle before trying to use it.
