Remarks

Notes to Callers

You should call IOleInPlaceFrame::SetStatusText when you need to ask the container to display object text in its frame's status line, if it has one. Because the container's frame window owns the status line, calling IOleInPlaceFrame::SetStatusText is the only way an object can display status information in the container's frame window. If the container refuses the object's request, the object application can, however, negotiate for border space to display its own status window.

When switching between menus owned by the container and the in-place active object, the status bar text is not reflected properly if the object does not call the container's IOleInPlaceFrame::SetStatusText method. For example, if, during an in-place session, the user were to select the File menu, the status bar would reflect the action that would occur if the user selected this menu. If the user then selects the Edit menu (which is owned by the in-place object), the status bar text would not change unless the IOleInPlaceFrame::SetStatusText happened to be called. This is because there is no way for the container to recognize that one of the object's menus has been made active because all the messages that the container would trap are now going to the object.

Notes to Implementers

To avoid potential problems, all objects being activated in place should process the WM_MENUSELECT message and call IOleInPlaceFrame::SetStatusText, even if the object does not usually provide status information (in which case the object can just pass a NULL string for the requested status text).

Note While executing IOleInPlaceFrame::SetStatusText, do not make calls to the PeekMessage or GetMessage functions, or a dialog box. Doing so may cause the system to deadlock. There are further restrictions on which OLE interface methods and functions can be called from within IOleInPlaceUIWindow::GetBorder.
