ON_MESSAGE(999,OnEndlabeledList) ... END_MESSAGE_MAP() And in your OnButton1 function you have to SendMessage(999); ----- We are what we repeatedly do. Excellence, then, is not an act, but a habit.

Easy way: you can break out the relevant code from the OnEndlabeleditList handler into its own public function, and simply call that, e.g.;
void CMyDlg::OnButton1() { CallSomeFunction(); }
Or you can, as you were trying to do, use SendMessage. You will need the window handler of the listbox window, or a listbox class, and call SendMessage on it and send it the appropraite message. If you look at the list box (or is it a list control??) documentation in MSDN you can find the right message. It'll look like one of these:HWND hListWindow = ::GetDlgItem(ITEM_ID_FROM_RC_FILE); ::SendMessage(hListWindow, message_id, wparam, lparam); // Or if you have a CWnd: theListCtrl.SendMessage(message_id, wparam, lparam);

SendMessage(999):eek: X| At least try something like#define MAGIC_MESSAGE WM_APP+99
(or some other number)
ON_MESSAGE(MAGIC_MESSAGE,OnEndlabeledList)
...
SendMessage(MAGIC_MESSAGE);MSDN states:
Message numbers in the first range (0 through WM_USER – 1)
are defined by the system. Values in this range that are not explicitly
defined are reserved for future use by the system.WM_USER is defined to be 0x400, so that your value of 0x3E7 (deimal 999) would send some message you did never intend to send to your window.
