Client rectangle not actualized after menu removal

[FloatingMarc]

Hi, In my application I can dynamically create a menu at the top of my window and also dynamically remove it. After I created it, calling "GetClientRect" returns the correct client area (previous area-area occupied by the menu bar). Now when I remove the menu bar, the client area is not updated. Only if I resize the window or move the window will the value returned by "GetClientRect" be updated correctly. How come? Is there a workaround? BTW I remove my menu bar with following code: [source] CMenu* it=GetMenu(); if (it!=NULL) { int nb=it->GetMenuItemCount(); for (int i=0;i<nb;i++)> it->RemoveMenu(0,MF_BYPOSITION); DestroyMenu(it->m_hMenu); } [/source] Or is there a windows function I can call to force a similar behaviour like when resizing the window? Thanks
