Answer 1

example:    static HWND   hwndEdit1; 
    static HWND   hwndEdit2; 
    static HWND   hwndCombo1; 
    static HWND   hwndCombo2;     POINT       pt; 
                // Get the edit window handle for each combo box. 
 
            pt.x = 1; 
            pt.y = 1; 
            hwndEdit1 = ChildWindowFromPoint(hwndCombo1, pt); 
            hwndEdit2 = ChildWindowFromPoint(hwndCombo2, pt);         ...........
        case WM_TAB: 
            if (GetFocus() == hwndEdit1) 
                SetFocus(hwndCombo2); 
            else 
                SetFocus(hwndCombo1); 
            break;
