ActiveX event delay

[Dimitris Vasiliadis]

I am creating an activex treeview control (ATL, VC++ 6, Win2000) to use it from an MSAccess form. I bind the control value to a field (RegionID, integer) in the form, and also bind a combo box in the same field. When I click some node on my activex control I fire an xxx_Updated event, and expect to see the combo box value change, but nothing happens, until my activex control loses the focus. Is this the normal behaviour or am I doing something wrong, because I was expecting the other controls on the form that are bound on the same field like my activex control to be updated immediately when I fire the _Updated event, and not wait until my control loses the focus. Thanks in advance for any help. The code I use to fire the event is shown below. LRESULT CTreeView::onclick(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled) {     if (FireOnRequestEdit(DISPID_VALUE) == S_FALSE)     {         bHandled = FALSE;         return 0;     }     UNUSED_ALWAYS(wParam);     UNUSED_ALWAYS(uMsg);      POINT pt;     TVHITTESTINFO hti;      POINTSTOPOINT(pt, lParam);     hti.pt = pt;     HTREEITEM hItem = TreeView_HitTest(m_ctlSysCtrl.m_hWnd, &hti);     if (hti.flags & (TVHT_ONITEMICON | TVHT_ONITEMLABEL))     {         TV_ITEM tvi = {0};         tvi.hItem = hItem;         tvi.mask |= TVIF_PARAM;         TreeView_GetItem(m_ctlSysCtrl.m_hWnd, &tvi);         put_Value(tvi.lParam);         FireOnChanged(DISPID_VALUE);         FireViewChange();         SendOnDataChange(NULL);         bHandled = TRUE;     }     else         bHandled = FALSE;     return 0; }
