COMMAND_UI

I have in mainfrm.cpp re: StatusCtrl
ON_MESSAGE(ON_MY_UPDATE_PANE1, OnMyUpdatePane1)
ON_UPDATE_COMMAND_UI(ID_DONE_RECS,OnUpdatePane1)
My
  SendMessage(hMain,ON_MY, 0,0)
gets to OnMyUpdatePane1
I now need to send a msg allowing
OnUpdatePane1( ) to update the pane
via it's    pCmdUI.
I would try
  SendMessage(WM_UPDATE_COMMAND_UI, ID_DONE_RECS
but there is none by that name.
How do I trigger this update event?

The message should be WM_IDLEUPDATECMDUI which is internally used by MFC. Instead, you can try calling ::AfxGetApp()->OnIdle(0) to trigger the update event.
